6/26    Upgrade to OpenSSH 3.4 ASAP:
        \_ so is 3.3 fixed too (i thought) or just better because of
           \_ 3.3 doesn't have a fix but if you enable priv sep on 3.3,
              the exploit won't result in a remote root explot
                \_ I don't know how you run your systems but i'd wager that
                   for most people (certainly for me) any remote exploit is
                   a remote root exploit.  There are simply too many local
                   exploits to always have them all fixed.
                   \_ Agreed. However one advantage of priv sep is that even
                      if sshd falls victim to a exploit, the intruder only
                      has user level access and them must find out which
                      of your local binaries have local exploits. This
                      leaves a trail which you can use to track the intruder
                      \_ Not really.  By the time they find a local exploit,
                         which will be about 18 seconds on a bad day, you
                         won't be tracking anything.  Once they get a local
                         shell with any account it's all over.
        \_ Thanks for the link.  I was happy to see a quick kludge in there.
           I don't have time to deal with a full upgrade for real right now.
           \_ Just so you know turning off ChallengeResponse is a hack to fix
              the one known exploit, but it isn't a fix for the whole class
              of exploits that were found and fixed by the OpenSSH team in
              3.4. Try to upgrade as soon as you can.
                \_ On my list for tonight.  I didn't want to do it remotely
                   and fuck it up and cut myself off from my server.  Thanks
                   for pointing that out.

6/24    OpenSSH 3.3 with Privilege Separation now available.
        \_ and why should we care?
           \_ BIG security exploit in openssh if priv. sep. is not
              enabled and priv. sep. is available only in v 3.3
              \_ The problem has NOT been fixed in the priv. sep. openssh.
                 However, privelege separated openssh supposedly diminishes
                 the possibility of root compromisse. Keep in mind that

6/24    I'd like to use Cygwin to manage my Redhat 7.2 box.  I can ssh in no
        prob, but when I try to open an xterm, it fails, with:
        xterm Xt error: Can't open display: server:10.0
        I can get X11 over ssh just fine from soda.  This is a stock 7.2
        install--nothing special.  Any ideas?
        \_ first did you try ssh -X
           and then have you tried ssh -v
           for verbose mode.
           \_ Yes, -X works fine, -v lists the following X11 related stuff:
           debug1: Requesting X11 forwarding with authentication spoofing.
           debug1: channel request 0: x11-req

              I don't remember what rpm contains it.
              \_ yes, xhost is installed.
                 \_ "xhost +" and try again.
                    \_ tried it with no effect (BTW, thanks for this help-- I
                       really appreciate it).
        \_ Found the solution.  My ssh connection set the DISPLAY on the remote
           site to "machine:10.0" instead of "localhost:10.0".  When I fix the
           display variable to use "localhost" it works just fine.
           \_ Just had the same problem a few days ago. Another way to deal
              with this is add your machine name ("machine" above) to
              /etc/hosts with your correct IP (if it's static). Then it'll
              work as-is, without requiring a manual reset of $DISPLAY every
              time. -alexf

6/21    Big bad apache hole in the wild.  Patch/upgrade now.  See
        or your favorite security site for details.
        \_ So they finally learned from Microshit?  "In order to gain free
           press we need to introduce security holes."
        \_ Does anyone think this vulnerability could lead to a fast spreading
           worm like  Code Red, for example?
        \_ What's the point? Apache + modules (esp. php) are full of holes.
           \_ So, don't use the modules you don't trust.
           Patch one, and there are still a hundred others that the '1337
           H4X0R5 will use to break in. Even if you patch all the modules,
           you still have all your executable content (perl cgi, ssi, php,
           servlet, jsp, etc) which is undoubtedly riddled with holes.
              \_ 1) try formatting.  2) just because there are other holes is
                 no reason not to patch this one.  3) glad you're not the admin
                 at my company.
           \_ It is possible but cracking a site by exploiting the holes
              in locally written code is much harder than exploiting a widely
              publicized and well understood vulnerability that possibly
              affects nearly every apache site out there.
           If you care about security, run publicfile.
           \_ publicfile does not support CGI scripts or any kind of server
              side programming which makes it fairly useless for lots of

           many architectures.
           \_ nnnn!  go read the security alert, not msnbc.
              \_ Actually I read all three.  Plus the apache one.  Plus the
                 debian security-announce summary.  It's a DoS explot.
                 \_ Well you didn't read the one that said it's a full root
                    exploit.  Whatever, go use telnet.  Not my problem.
                 \_ At least one exploit (for openbsd) has already been posted
                    on bugtraq with intent to prove people like you wrong.
                    \_ If your OS doesn't execute data off the stack, it's
                       not exploitable (but it's still DOS).  And it's not
                       a root hole, just the user Apache runs as.  Still,
                       it's potentially bad.  -tom
                       \_ Lots of people run apache as root.  Lots of sites
                          that run apache as 'www' or whatever will also have
                          local holes if they haven't fixed this one.  Thus it
                          is highly likely that getting in through apache is
                          just one step from root.  Layers....

6/21    Since keyinit has been disabled and ssh doesn't work for me (behind

        csua?  Already tried ssh with http-tunnel and socks2http.  -allenchu

           and ssh in from there. -Someone who ran out of keys too.
           \_ People like you are simply irresponsible bastards. You know
              the difference between telnet and ssh but you're still insisting
              on using telnet, potentially compromissing not only the security
              of your personal account on both machines but also compromissing
              the host security of both machines in general. Lots of root
              breakins start with sniffed passwords. But you, of course, don't
              give a flying f**k to this because you're probably not the one
              who will end up fixing the problems later.
              \_ If the company's firewall didn't block port 22,
                 he would of use SSH.  Just because you are an irresponsible
                 idoit doesn't mean everyone else is.
                 \_ that's not an excuse for using telnet and
                    jeopardazing the security of the entire machine. I am
                    also surprised that a company that filters outgoing
                    ssh still allows outgoing telnet.
                    \_ I doubt there is one.  It's too stupid to comprehend.
        \_ How did you post your question without logging in?
           \_ Because I have ssh at home. Also have a few keys left.
        \_ can you ssh to port 80 on scotch.csua
           \_ Thank you.  This might be it.  Of couse this assumes the
              lovely M$ proxy that prevented http-tunnel to work will
              not do the same to this solution.  -op

6/20  I'm so confused.  Isn't a non-routing network?   ...
        \_ should not be routing these packets. Neither should
           XO really, but they might have an agreement with CNC that
           makes it hard for them to filter traffic.
        \_ Welcome to the world of routing.  Sadly, certain Network Operators
           are, shall we say, less than clued.
        \_ A lot of providers use RFC1918 addresses for 'private' interfaces;
           frame relay clouds are a good example of this.  They're not
           supposed to be routed, but rather just used within a given
           cloud or circuit for routers to be able to contact each other.
           Sometimes routing information about these slips out, when someone
           exports a default route, or doesn't filter correctly (correct
           me if I'm wrong, but aren't some protocols, like OSPF, a pain
           to filter individual routes/networks with?) so people with
           different providers will see these addresses as "existing"
           in various places.  Shouldn't do any harm, it's just not very
           clean.  -John
           \_ still, one shouldn't be using RFC1918 addresses even for
               transit links, as it will get important ICMP messages generated
               by the routes filtered out.  Things like unreachables and
               fragmentation-needed stuff. Its sloppy/bad practice. -ERic

                  lot of filters like this, but for some reason, various
                  transit domains like esnet are refusing to do so ... they
                  are saying there are some performance issues ... we didnt
                  argue much or demand to see the evidence but it is possible
                  there is sort of a reason, i.e. even if the overhead is
                  small, the fraction of these packets is vanishingly small

6/12    What's the ANSI escape sequence for setting colors 8-15?
        \_ colors 8-15 are just high-intensity versions of colors 0-7.
           to set the high-intensity attribute, use {ESC}[1m
           see also:
           \_ Hm... interesting.  The reason behind this question is that
              colors 0-7 in SSH Secure Shell are very dark.  I'd like to
              use termcap/terminfo to trick programs to using colors
              8-15 (which look normal).  I've tried using Esc[1m, but I
              get the brighter color along with a bold typeface.  I'd like
              to get just the brighter color but not the bold typeface.
              \_ don't use colorls?
              \_ Unless you can change something in your terminal program's
                 options itself, you're fucked. Try another ssh client.
                 PuTTY is good. Teraterm is usable but doesn't do
                 ansi colors iirc.
                 \_ Teraterm actually does.
                 \_ Putty is nice when you need something fast for a one shot
                    but for daily use I prefer terateam which doesn't feel like
                    someone's HS project.
                    \_ I'm curious -- name one thing that teraterm does better
                       than the current stable version of putty. I've used all
                       3 ( client, tterm pro, putty) for quite a while
                       and now just use putty because it's acted up much less
                       often than the others.
                       \_ For starters, putty is the only ssh client that will
                          spontaneously drop my connection all day every day.
                          It's not an idle time issue, it'll do it in the
                          middle of typing.  There were a few other personal
                          preference differences but I consider disconnects a
                          serious issue.
                          \_ Strange; I've never had that happen over several
                             months of using putty (unless the network went
                             out with it). Are you sure it's not a problem
                             with your server's sshd (which the other clients
                             may be more tolerant toward)?

5/8     I'm thinking about using a block cipher to encrypt pkts
        in my application, but I'm running into a problems wtr
        transmitting/receiving the encrypted pkts. Here is
        what I want to do (given values are secret key K, plain
        text PT):
        1. Derive K1 (encryption key) from K and a random nonce
           N1 and derive K2 (HMAC key) from K and a random nonce N2
        2. Encrypt PT and H(PT) using K1: e = E(H(PT)|PT,K1)
        3. Calc. HMAC of the e: h = HMAC(e,K2)
        4. Transmit N1|N2|e|h (this would be a fixed size pkt)
        5. Recv. N1,N2,e,h
        6. Derive K1 and K2 from K using recv'd N1 and N2
        7. If HMAC(e) = h, then decrypt e: D(e,K2) = H(PT)|PT
        8. If the decrypted H(PT) matches a computes H(PT)
           return PT.
        What I don't know how to do is recover from the following
        * HMAC(e) of the recv'ed e != h
        * Decrypted H(PT) != computed H(PT)
        Since it it unlikely that the pkt was corrupted by trans.
        errors (I'm using TCP), the only way that this could happen
        is because of an active attacker. Is there any point in
        asking for a retransmit on the recv side if an active
        attacker is present?

2/21    My moronic boss asked me to write a batch file to auomate a telnet

              machine's at a client site; none of these machines have ssh.
              How do I tell him off?  I told him it can't be done and he
              insisted that it can be done.
              \_ Why are you still even working there? I can't imagine
                 working in a place with a boss that stupid and an OS

        \_ He's a moron, true, but you've done your duty by telling him so, now
           it is your job to make it work.  I suggest a telnetd that auto-auths
           anyone with no password.  Yes, this is frightfully stupid, etc, etc,

           documented that this is insecure and you told them so but were told
           to do it anyway.  You're then free from serious fallout.  C.Y.A.
        \_ I agree with the SSH suggestion. However, if you still need to
           use telnet, you can embed a known password into the batch script.
           You need to telnet to the same account, though. Or maybe have
           the user save the password somewhere, but not ask on every
        \_ Create a server on a random port that does what he wants and have
                your script telnet to that port.
        \_ write a telnet program that automates the password and ship
           it with your batch file.  And document it that it's insecure.
        \_ Upgrade windows. Realize that even windows has better tools
           than telnet for running remote batch jobs.
        \_ Whatever you do ignore the idiots here who give the 1990's dotcom

2/19    Tom posts an intelligent comment on usenet:
        \_ Charging is one possibility except then you get into the problem
           of exactly who to charge.  Do you charge the student assigned to a
           workstation?  Ok, another user logs in from another local machine
           and uses the other student's machine for external access.  Do you
           charge the whole department or sub-unit and "let God sort it out"?
           That just means rich departments stay on the net and poorer ones
           take the net away from most of their users.  You can't charge by
           IP address because IP != unique user and packets don't have user
           names on them.  There's still no answer short of simply cutting off
           a lot of people from external net access and I don't think anyone
           wants that.
           \_ "tragedy of the commons" problems usually have no easy solution.
              The issue of access to national parks is a good example; you
              can't restrict access to Yosemite Valley in a way that's
              pleasing and fair, but you have to restrict access if you want
              Yosemite Valley to retain its value.  At some point you have
              to make some decisions about tradeoffs.  A campus phone isn't
              equivalent to a unique user, either, but we manage to bill
              people for phone service.  -tom
              \_ I don't have a problem with the basic concept of billing for
                 usage but it isn't the same as phones.  Most people aren't on
                 the phone all day.  Most aren't making LD calls.  And it is a
                 bit difficult to login to your phone from my desk without your
                 knowledge and rack up a huge bill to 976-hotsex.  $300 in
                 calls on my phone to my office mate's mother in Tokyo is easy
                 to track down and bill properly.  With the technology at hand
                 I only see raising bandwidth or cutting a lot of people off
                 from the public net.  I don't see the latter as a good choice
                 for a research/educational institution.  It also wouldn't fly
                        \- i think this is naive.
                 \_ How are you planning to pay for this increased bandwidth?
                 \_ I don't think anyone wants to cut people off the net,
                    but providing a certain amount of "free" service, and
                    charging if you go over a certain amount of traffic, is
                    probably a tenable model.  Buying bandwidth indefinitely
                    so kids can fill it up with more kazaa is untenable. -tom
                    \_Just raise tuiton. Make net access a line item that
                    people can elect not to pay for if they don't need it.

                               using gnutella for collaboration or maybe some-
                               body in cs doing something researchy] solve the
                               problem as long as someone in the dorms can

                               is possible]. are students on the dormnet
                               allowed to run WEEB servers? yes, a lot of the
                               http is garbage but you have to attack what is
                               viable and cost-effective. the comment about
                               running the p2p server on port 80 to "hide" is
                               not a real issue. at least with napster,
                               gnutella, kazza, we can detect it on any port
                               [although not in real time, although that doesnt
                               seem important]. Also, the TotC comparison isnt
                               quite right since the Commons is a natural
                               endowment while bandwidth is sort of a "weakly-
                               rival" good paid for by somebody. Say I build a
                               lighthouse for my shipping company along my
                               shipping lane. I dont care if some people use
                               my lighthouses, however if this makes for "my
                               shipping lanes" too crowded for me to use,
                               well, i'd be better off switching technologies.
                               it seems like if you throttled the dormnet
                               traffic onto the routed internet but allowed
                               significant bandwidth to campus, people could
                               do their school work. [i assume most of the
                               p2p sharing isnt local]. --psb
                               [the lighthouse example is a little off because
                               it is not a divisible but a binary good but that
                               wasnt the point i was getting at. someone does
                               own the bandwidth].
                                \_ dorm traffic is already handled under
                                   a separate cap.  You can do things to
                                   discourage P2P sharing, but that only
                                   solves 25% of your problem, and the
                                   more you discourage it, the more incentive
                                   there is to find ways around it.  -tom

           limited to ~20Mbit.  That's 4,000+ hosts.  UCB dorm net is pretty
           much useless these days.  Residents keep trying to get DSL
           installed because it's faster.

              access to the staff/professor modem bank and off the busy and

                      becomes useable again.

                           isn't worth anyone's time to fix the dorm net
                           situation.  Who cares?  Let them eat cake!  Is
                           there a minimum bandwidth promised or an SLA in
                           the current dorm contract?  Do people *really*

                        \_ Clearly, that's the way campus wants to go, but

1/10    So I've decided that since my system is vulnerable to one kind of
        attack to not bother with any sort of defenses.  I'm reinstalling
        telnetd, disabling ssh2, running an old version of ssh1, putting IIS
        4.0 unpatched back into production, get 8.01 bind going and then
        setting the root password to "root".  Does this make sense to anyone?

        way to get in that isn't covered by the current patches?

12/15   I have cable srevice by at&t, but I don't think this is a problem
        with my cable service.  Basically, I have a linux 2.2 natd box for
        connections from my internal network.  I have win98/ win2k/linux
        behind the natd box.  WHen I ssh out (OpenSSH_2.3.0p1 or ttssh),
        if I am idle for say, 5 mins, the connection is cut..reset
        by peer.  Why does this happen, and how do I fix it?
        \_ I don't have this problem with a similar setup.  Could the other
           side be idling you out?  I _have_ had that problem.
        \_ This is a problem with ipchains. It doesn't have any state, so
           it has no idea about connections and things like that, so to keep
           from having NAT sessions open forever, it has timeouts for inactive
           NAT sessions. I forget where you change this (it's been years since
           I used ipchains, since iptables (linux 2.4 filtering) is so much
           better.) however, I'll bet money that that is your problem. Look
           it up in the ipchains HOWTO, I believe it is in there, and increase
           the timeout for TCP, since the default is something low, like 5
           minutes. There may be a way to get ssh to send connection keep
           alive packets, which would solve the problem without having a large
           timout value, so I'd look into that as well. Or, just switch to
           2.4, and use iptables. Stateful packet filtering is your friend.
               -- ajani
           \_ thanks!  when i was using ipf on openbsd I kind of took this for
           \_ NAT is stateful by definition. You can't do NAT without keeping
              session state information. NAT session timeouts exist in all
              implementations, not just ipchains because if you don't expire
              the idle sessions, there is a higher chance that the NAT session
              state table will eventually fill up. What Linux iptables adds is
              a session state tracking for non-NAT sessions as well.
           \_ Uh, the ipchains NAT session timeout default is way bigger than
              a few minutes. Check the HOWTO, it is more like several hours.

12/7    What is the best way to transfer funds between accounts in U.S. and
        another country (in Europe) without fee or getting riped off
        by special conversion rate?  The amount is small and just to cover
        my expenses when I travel or order internationally, i.e. < $2000.
        \_ My dad has a US checking account at B of A.  Every month I make
           a deposit to his account at a branch here, and he withdraws the
           money at a branch in Hong Kong.  No transaction fee, but I don't
           know if the conversion rate is the same as the standard rate.
           \_ I asked at the Bank of America in Hong Kong whether
              one can access his US account in HK, the answwer I get
              is plain no, as Bank of America Asia supposedly cannot
              access account of its parent bank in US.  If you are
              converting from USD to a foreign currency, you are bound
              to pay a conversion fee (3% I think in most banks). You
              can open an USD account in a more established financial
              houses (like SG), so you can withdraw funds outside of US
              much more easily.  But for $2000, it's easier to get
              travel's checks.
              \_Tnx for the reply.  However often the need to transfer
                money arises and the amount becomes known while I am outside
                U.S., not to mention carrying traveler's check is like
                carrying cash other than being much safer.
                \_ I've heard from a lot of people that ATMs are good,
                   you get better (minimal but still significant)
                   fees. Better than changing cash out.
                   \_ but you cannot deposit foreign currency to your account
                        from abroad.
                        \_ Go back and read the stated objective, duud.
                \_ Use your credit card. You'll get the best exchange rate
                   and if you pay it off, the fee will be minimal. No cash
                   that you need to carry which should eliminate the cost of
                   \_ Depends. While I was in Europe this past summer, it was
                      cheapest for me to just withdraw cash from ATMs: BofA
                      was tacking a "foreign currency conversion fee" to each
                      of my CC transactions, while for the ATM withdrawals, I
                      was getting the interbank exchange rate without any
                      additional fees.  When I lived in Germany, I had my
                      paychecks direct-deposited to my credit union account
                      in the US and paid for everything in cash: if my needs
                      exceeded the daily transaction limit, I planned ahead
                      and visited the ATM multiple days in a row.  If you
                      want an account at a bank that has a presence on both
                      sides of the Atlantic, I've heard that Citibank and
                      HSBC are good choices for US->Europe expatriates,
                      although I have no experience with either.  -- kahogan

                   Their rate is horrible.  (something like 8%)

                 himself a check and then cash it at a B of A branch there?
                 I've never asked him.

10/7    I'm starting to dig rsync and ssh.  There's some
        caveats that aren't clear to me yet such as how to
        create a passphraseless key but still be able to limit permissions
        on the key.  Anyone know how to do that?
        \_ keychain might be the best you can get-- it keeps your ssh-agent
           running as long as the machine is not rebooted.  That way, you
           can log in to foo, start ssh-agent running in the background,
           add your identities, and use 'em till foo reboots.
        \_ What do you mean?  Without a passphrase on your key,
           anyone with root on the machine your "identity" is on
           can read your key and use it.  With a passphrase, someone
           with root can STILL get your key, but they have to work harder.
           If your key is on a machine that you're certain won't be
           compromised, with absolutely trustworthy root, then you don't
           need a passphrase. If your key is in an NFS-exported directory,
           you need a passphrase.
           [ reformatted ]
           \_ I think what he's trying to say, is that is there a way
              to set group permissions on a passphraseless key so the key
              can only be read by a certain gid (i.e. group foo).
              I don't think this is possible.

           all IMAP clients to see the same view. In addition, clients can
           resync their folder cache and manage folders and email offline.

8/17    On 18 July, just as Code Red was starting to scan for vulnerable
        web servers, a CSX train carrying hazardous materials was
        derailed in the Howard Street tunnel in Baltimore, US.
        The derailment and subsequent fire severed cables running through
        the tunnel used by seven of the biggest net service providers to
        swap data.
        These companies started reporting disruption to the usual running
        of the net just as Code Red was hitting its stride, leading many
        people to assume that the worm was doing the damage.

        posed no threat to the running of the net.

6/18    I have a question about diffie-hellman. After going through the initial
        key exchange and generating the session key k', how do you use this key
        with 3des or blowfish? Do you just trucate the key to the appropriate
        length (doesn't seem right) or is there some other method?  tia.
        \_ Probably feed the key into a one way hash function (i.e. MD5) that
           outputs the appropriate number of bits.
           \_ This is correct.  You would use a hash function.  However, you
              should not use Diffie-Hellman straight, much the same as you
              should not use plain RSA.  Get a cryptography book and read
              about it.
              \_ Okay, I understand the bit about the hash function, but
                 I don't understand why the session key k' can't be used
                 directly? I've been referring to Applied Cryptography,
                 but I can't seem to find a place where he explains why
                 the session keys should not be used directly.
                 \_ Here's a hand-wavy argument:
                        Your DH key must be larger than your 3DES key since
                        otherwise it's easy to break DH.  This means that
                        you'll have to shrink your DH key to make your 3DES
                        key.  You want to make your 3DES key by using all of
                        the randomness that you've got in your DH key, but
                        you don't know if truncating the DH key will do this.
                        However, you DO know that using a good hash function
                        to make your 3DES key will conserve all of the
                        randomness of your DH key.
                        \_ I guess I wasn't clear. I understand that I
                           need to hash the session key in a way that
                           preserves the randomness of the key and that
                           I need to use the hash value as the key for
                           my crypto algorithm.
                           The bit I don't understand is related to the
                           following: I keep reading that one should use
                           the hashed value of the session key *only* for
                           encrypting a different secret key and then that
                           encrypted secret key should be transmitted so
                           that all other transmissions are encrypted with
                           the secret key rather than the hash of the
                           session key.
                           Why can't I just keep using the hash of the
                           session key? It seems much simpler to do this
                           than to maintain a separate secret key.

6/12    Here's the bottom line: The RIAA wants to control all channels
        of distribution. For a user to access his own "private"
        collection may infringe upon the notion of "ownership." Meaning
        that by leaving those mp3s on an "open" (yes it is open because
        you have access to it outside of the LAN) network exposes the
        user to "potential" distribution infringement.
        attempted something like this but the RIAA nuked that idea
        right out the water. The way it would have to work is if the
        RIAA forces the user to license each component of music that
        he/she has access to, regardless if they had, indeed, purchased
        it. Why? Because the RIAA can track that information still.
        How? Through the networking software. Tapes and CDs prove to be
        untrackable in terms of distribution but software is trackable
        especially over networks. As long as the RIAA can track their
        distribution, no user truly can have that sense of privacy. In
        terms of tapes and CDs, the RIAA would have to invade each
        suspected user's home and then provide a warrant to search
        their premise. That's ridiculous in terms of overhead.
        Networking software makes usage tracking simple. The idea won't fly.
        I might've been talking about mp3 cell phones that are
        distributed by sony a while back. The reason why those are
        novel (albeit not necessarily popular) is because 1) it's Sony
        and DoCoMo doing the distribution; 2) the method of transmission
        is done through the memory chip. The memory chip is portable
        and removable so it's effectively like copying onto a tape.
        Supposedly the new G4 technology being pushed by DoCoMo will
        have a Java client that gets streaming audio/video to your
        phone. If it does, you can guarantee those lines won't be
        private and if they are it'll be challenged in court. - keithyw

5/25    If IPv6 encrypts everything (IPSec) as part of the standard, does this
        mean protocols like ssh would no longer be required?  Will IPv6 allow
        telnet and ftp and other cleartext password protocols to live on?
        What use would there be for ssh if IPv6 was everywhere?
             \- i realize i am "begging the hypothetical" but the "if ipv6
             was everywhere [and interoperating nicely, with reasonable key
             management, and transparancy]" is a pretty big if. "if ksh does
             everything sh does and more, why do we still have sh?" etc. --psb
                \_ It's a good question.  I think the answer is mostly just
                   inertia and history.
        \_ there will always be a need for application-level security
           \_ What does ssh do for me that ipsec doesn't?  IPv6 encrypts, it
              compresses, QoS, and lots of other funs things.  What does ssh
              get me in a pure IPv6 world? (Yes, I know this will take a while
              to happen, that's not my query).  Don't get me wrong.  I love
              ssh and use it for all sorts of stuff.  I'm just not seeing a
              big role for it in IPv6.
              \_ Authentication?
                 \_ I think a telnet prompt with memorised password is better
                    auth than the keys-on-disk ssh standard auth.  I can steal
                    your private key.  I can't read your mind.
                \_ you can require a key on disk, and protect the
                   key with a passphrase
                    \_ Is stealing someone's private key easier than reading
                       their password out of the password file?
                        \_ Yes.  And can be more useful.
                    \_ Of course -my- private key is encrypted. Go ahead and
                       steal it. As for memorized password, it can be easily
                       stolen as well with a use of a trojaned client or
                       server, and I have seen this happen many times.
                        \_ So you unencrypt your key before each use?  Uh huh.
                           If the server or client is trojaned all is lost
                           anyway so it hardly matters what you use at that
                           point, does it?
                           \_ This is not true in general.  It's easy to
                              authenticate yourself without revealing
                              your private key.
                           \_ Yes, man ssh-agent. And if your are not using
                              ssh-agent, then yes, you need to decrypt the
                              key every time you use it. Ssh client does this
                              for you. And yes, this is more secure because
                              you don't have to send neither your password
                              nor your private key to the remote ssh server.
                                \_ I think you don't understand how ssh-agent
                                   or ssh itself works.  ssh-agent is a local
                                   key manager that makes it so you don't have
                                   to retype your passphrase over and over for
                                   each new connection.  Nothing more.  I'd
                                   like to hear your explanation of how it
                                   auths to the server without sending any
                                   \_ do you even know what PKI means?
                                      \_ Same question: how are you doing auth
                                         without sending someone something?
              \_ i was speaking more broadly, e.g. SSL too.  the main use
                 of app-level security is authentication and integrity
                 of data between app-level (not system-level) principals.
                 \_ Is something like app-level ssl necessary when the
                    underlying protocol (IPv6 in this case) deal with it?
                    \_ yes, particularly for distributed systems. not
                       only are there app-level principals that are not
                       known at the system level to auth/authz, but
                       you also want to reduce the extent of damage when
                       one part fails.
        \_ Agent system, agent forwarding, x11 forwarding...
        \_ BTW, IPSec has nothing to do with IPv6.  Implementations of both
           for *BSD systems happen to be codevelped by the same people
           (, but IPv6 !=, is not a superset of, does not imply,
           whathaveyou, IPSec.
           \_ Well, true, but what I read implied that IPv6 is assumed to use
              IPSec by default.

        (How to get 128-bit encryption from your Airport base station)
        \_ too bad you cant get 128bit from the builtin airport interface
           on their laptops. --jon
        \_ Rumor has it that 802.11b (including AirPort) are going
           to 54mbps w/128bit encryption in the coming months.
           Also, above url states AirPort has 64bit encryption,
           which is wrong, it's 40bit, which everyone knows
           you can pretty much break on the fly with your laptop
           and a little reciever.
           \_ 802.11b will never be 54 MBit. 802.11a will be. Its
              scheduled to be released in the fall/winter of this
              Most people say that you will probably need a new
              Airport card, but that you can probably upgrade
              your base station.
       \_ Uh, wtf is the point?  The Gold and Silver levels of 802.11b
          encryption have both been cracked.  Run IPsec with however many
          bits you want...
          \_ Its not "encryption" is Wireless Equivalent Privacy. The

           \_ That can easily be remedied by having sshd listen to a port
              that the firewall allows instead of 22.
                \_ Ok, I dug further into it (I'm remote so this is all through
