\_ That's hardly a "good" bumper sticker. It's completely lame. Or

\_ I saw plates once that said 3BPD826.
\_ What does that one mean?
\_ Not a God damned thing. It's a license plate.
\_ Lamer in my complex with GO7 R3WT
\_ I saw some dolt with "port 80" Who would do this?
Tim Berners Lee perhaps? _/
But I believe he lives in
Geneva so its probably not
him. I've also seen "httpd"
as a license plate. Thought
that it was pretty lame.
I saw RFC1771 and figured
it was Tony Li's car.
I think that a plate that
said RFC1149 would be really
cool, provided you contributed
to it.
Made me want to go get "port 70" now THAT would be L33T

3/9 I just changed my shell to bash (from tcsh) but it won't read
my .bashrc or .login file when i login. What file in my home
directory will it source upon login?
\_ RTFM lazy ass
\_ Why would you do something like switch your shell to bash? Sure,
go ahead and write scripts in it, but use it as your everyday
shell? Damn.... Than again, if you can't figure out how to read
a man page, then maybe you weren't getting any real use out of tcsh
anyway, so it doesn't matter what shell you use. Get a GUI file
manager.

How do you fucking exit out of emacs?

\_ uhm, no. C-x C-c

\_ Same difference. You never hit shift with control since
there are no shifted control codes in ASCII.

\_ so if i just want a vi ":q!" function i can just get rid of the save
cmd?
\- no, then just run kill-emacs. --psb
\_ oh yeah. so do you know why I get ".#foo" links for each
modified buffer when I kill-emacs?
\_ They are auto-save files, emacs thinks that you exited
by mistake and keeps those around in case you want to
recover them.
\_ yes but I disabled auto-save and I still get these
links, that point to my email address and shit.
there's nothing useful about them and I can't get
rid of them. Emacs reminds me of Windows.
\_ auto-save is a per-buffer thing, I don't think
it can be globally deactivated.
\_ I've been using Unix for about 9 years. I have one question:
How do you fucking exit out of vi without saving?
\_ :q! ; find / -depth -type f -name "*vi" -print | xargs rm -f

3/5 According to the solaris sysadmin guide I need to be in single user
mode to do a dump/restore. I've tried dumping when I'm not in single
user mode and it works fine. Should I be afraid that anything bad
might happen? Anybody had any bad experiences with ufsdump in user
mode? Thanks.
\_ It'll complain sometimes if a file changes while it's backing it
up, but it basically works fine. -tom
\_ referential integrity cannot be assured if dump is performed
in multiuser mode.
\_ Do you care about data integrity? If you do, then you should be
in single user mode, since you can better control the accesses
to the filesystem.
That said, if you are doing this at home on your personal box,
with one user and maybe the web/ftp server running, its not a
big deal.
\_ just curious, can you force remount the filesystem into read-only
mode, then dump it, then remount it rw? Might solve the integrity
issues, and only lose you last-access-time information. -ERic |

2/22 Is there any advantage of tcsh over bash? I've always used tcsh for
my shell and sh for programming. I'm wondering if tcsh has anything
(other than automatically setting $REMOTEHOST) that bash doesn't.
\_ one thing I like about tcsh that bash doesn't have is you can hit
^D on an attempted file complete, and it will list possible
completions. Pretty useful if you dont remember the exact file name
and dont want to have to abort and retype a commandline just to
do a 'ls'. (well this isn't a default bash option, it may exist,
I just find it easier to 'exec tcsh' than 'man bash') -ERic
\_ in bash, you hit tab twice. $ ls foo^I^I[expansion list returned]
but you can get this particular interface in tcsh as well. I
imagine it's a holdover from csh filec. --jon
\_ If you put "set show-all-if-ambiguous on" in .inputrc you will
need to hit tab only once in most cases.
\_ tcsh has a convenient %~ option for the prompt. Does bash have
a similarly simple counterpart?
\_ what does the '%~' option do?
\_ it prints your current working directory with respect to
your home directory (e.g.: ~user/somedir). man tcsh
\_ Of course bash can do silly things like that. You can
put about anything in your prompt. man bash
\_ I did man bash and didn't see anything about this. Is
there way to do it that is as simple as in tcsh? And
as far as "silly things" goes, realistically, I think
that as far as important (ie, "non-silly") features go,
bash/tcsh/ksh are about the same, so it's the little
things that make the difference.
\_ PS1="\u@\h:\w\\$ "
\_ this only works for directories off of your own
home dir, not off of other users'.
\_ okay. I use ksh, I'd use bourne shell if I could hack
in filec and arrow keys for history. This sort of
stuff is frivolous.
\_ Use zsh. The best of both worlds. (In fact, all most all of both
worlds)
\_ /sbin/sh is the STANDARD shell! Real men know how to type and
don't need fancy line editing. Use Bourne Shell as God and Steve
Steve intended. Though Korn Shell is the spawn of the Devil and
David Korn, its use can be tolerated on systems with clueless
admins who think that /bin/csh (Bill must have been intoxicated
or stoned when he wrote this) is the best thing since DECNET
and LAT came out.

identify yourself if not the hostname if you want to have at least
a chance of the rest of the motd monkeys treating you as anything

by default suspiciousa, and anonymity only solidifies certain

\_ I can point my machine at a different DNS server by
editing /etc/resolv.conf or whatever, thus a rejecting
route or a blackhole is the only soln.
\_ no. You can't. Why not? Because you're a non-techie
at a large company with a no-surf policy and you don't
know jack shit about that. If it were a unix box you
wouldn't have root at this person's company.
\_ Thanks, but I do want to let them access most web sites
except ones I exclude. Is there a plug-and-play solution?
\_ Yes. Like I said, you add things like http://cnn.com to your
local DNS as something else. Everything else works.
\_ The easiest solution is to get a switch and a proxy server
that can do transparent redirection of http requests to force
them all through the proxy which does filtering. (Set up one
with enough space to do caching and you'll also lower bandwidth
usage and increase access speed.) Look at products from companies
such as Alteon, Foundry, and Cisco on the switch side, and
NetApp's NetCache or something similar on the proxy side.
\_ Why? Do you like pissing your employees off? Are you trying
to convince them all to quit?

12/7 POSIX question. Is it true that errno is only valid if a function
fails? E.g. I have something liek this:
foo = strtoul(...);
assert(errno == EOK);
I'm getting an assertion failure even though everything is ok.
Somebody told me that POSIX standard specifies that errno is only
set if a failure occurred. Is this true?
\_ Errno is ass. It is not thread safe. Don't use it;
if a function needs you to use it, don't use that function.
-blojo
\_ Errno is thread-safe in POSIX; the name "errno" gets #defined
to a macro that returns the current thread's errno. See errno(2)
or /usr/include/sys/errno.h.
\_ could be that somewhere in strtoul EINTR or EINVAL is being
set. AFAIK, strtoul does not set errno. Rather it returns
ULONG_MAX on failure. It can also return 0 and set endptr
(2nd arg) to non-null on a failure (provided you use that
feature). ----ranga
\_ whoa...
\_ I'm asking about a more general question. strtoul is just
an example. In general, is errno set to EOK if everything
is ok? Or is it's value undefined if there were no errors
in the function. Somebody is telling me that according to
POSIX, errno is valid only if a function fails in some way.
\_ errno is only set on an error. checking EOK is not a
valid method of know if a function returned successfully.
from the man page:
"Successful calls never set errno; once set, it
remains until another error occurs. It should only
be examined after an error."

\_ Why do you use so many dashes?
\_ no particular reason. I've always signed
my name that way in email/news/etc.

11/28 NIS question. My nsswitch.conf has the line
passwd: files nis nisplus
To me this says that the user should be looked for in the passwd file
first, then checked for in NIS, then NIS+... Yet when the NIS server
isn't available, I have to wait for a huge timeout before I'm finally
logged in (yes, there is an entry in the passwd file). Why does this
happen and how do I get the expected behavior? -mogul
\_ It's probably doing something other than a passwd lookup.
You'll have to truss the process to find out what. -tom
\_ Or you can check for other nis lines in the nsswitch.conf
automount, group, hosts may all be blocking on nis lookup.
It may be something in your .login/.profile/.[t]cshrc file
causing an nis lookup as well (like having someone else's
homedir referenced in your path). --scotsman
\_ If it's stalling in .cshrc, I think there is some option
you can set in .cshrc to show you where. Put a line with
'set verbose' or something at the top of .cshrc
And if you have root, then login as root and see if
the problem still exists. Since root has simpler dotfiles
and should have no remotely mounted home dir, you can
use it to narrow down the possible problem.
You might also modify nsswitch.conf
\_ Yes, but only if I log into another client served by NIS.
My home directory gets mounted from my main machine. On
my machine, the passwd home directory entry is set to the
local directory so it doesn't go through autofs... -mogul
to remove nis and nisplus and see what happens.
Make sure you have another xterm open however
just in case modifying nsswitch.conf locks you out.
Also try getent passwd YOURUSERNAME and see if it says
what you think it should be (i.e. is your home dir
really on your local desktop disk?)
Also check /var/*/messages file for errors
\_ what's in the groups line? is your default group in a file
or in nis? initgroups usually takes forever
\_ groups line was fine, but my group was missing from local
/etc/group. Still didn't solve the problem though. I will try
tom's suggestion when I return to work. -mogul
\_ These things are often due to DNS problems.
\_ is your home directory auto-mounted? could be the auto
mounter maps are stored on the nis server.

\_ Ask a fucking lawyer.
\_ Yes. RMS wants it all. Stupid you for picking COMMIE GPL
tainted code.
\_ IF you include GPLed code in your program, your whole program
falls under the GPL. This is a deliberate "feature": that it is
viral in nature. The key difference between the GPL and LGPL
is that the LGPL, since inteded for libraries, is that only the
origional portion is under the LGPL, the rest of your program
is not. One of the initial bugs in Bison is that the output
was covered under the GPL and not the LGPL (a situation since
rectified).

\_ The GPL doesn't affect one bit how much you charge for your product,
for free to anyone that asks, less medium copy costs.
it just gives your customers the right to give it away to anyone
they want at any price they want, including for charge or for free.
Sooner or later it will probably end up in the hands of someone

I want to distribute a .c file that I sell with my

\_ Only if the .c file is part of your product. Look at
all the major Unix vendors - they include GPL'ed software
with their OS'es, but their OS'es aren't GPL'ed.
\_ I was talking with a friend about this and the
opinion was that if we distribute the GPL'd .c file
with the intention that the user can link it in
with our source, then it becomes iffy enough
that someone can sue us if we don't GPL the
entire proprietary product.
for free to anyone that asks, less medium copy costs. I can
still sell my proprietary product for however much I want,
but I have to give it away free to anyone that asks.
\_ No you don't - you have to include source or provide it
at a reasonable cost for media for anyone who has a
binary copy, but you don't have to give it away for free.
\_ "less medium copy costs"
\_ Okay, so I've done some research on the GNU GPL, and the basic
idea is that if you link GPL'd source with your product, then
your product becomes GPL'd, and anyone can take your product's
source and make an improved version of your product. In other
words the GNU GPL "encourages" free software, which leaves the main
revenue stream for GPL'd software to grants and support contracts,
and co.'s like Red Hat that would pay programmers to write GPL'd
software. Is that right?
\_ there's also the GNU Library license. take GNU libc. one can
link to it and still keep his or her code proprietary. -dpetrou
\_ Yes. This is correct. The GPL is an evil virus license.
\_ Well, free software isn't a bad thing. The GPL definition
and intent should just be more clear to the lay programmers.
\_ I'm not opposed to free. I'm opposed to virus licenses.
\_ BSD is a free license. GPL (and variations) are not.

10/23 on a Sun (solaris). if i use BASH and type grep i get gnu grep,
if i use [not BASH] i get the Uber-LAME grep that comes with
solaris. "which" indicates that they are the SAME grep. What
the hell is going on?
\_ Your fu is really weak, this is a $PATH problem.
\_ If your fu is so great why don't you explain WHY "which"
is leading me astray.
\_ Your problem is most likely related to "which"
screwing up when looking at $PATH (it screws up
because its a POS csh script). $PATH is set in
a shell's init scripts. Depending on your shell,
its value will be different. "which" is too stupid
to figure all this out and just gives you the lame
csh setting.
When using a Bourne shell (/bin/sh, /sbin/sh on
Solaris) or a Bourne-compatible shell (bash) use
"type" instead of "which" as God and Steve intended.
When using Korn shell, you should exec /bin/sh
and rm -f all instances of David Korn's greatest
mistake. If you insist on using a csh compatible
shell, please shoot yourself in the head or jump
in front of a car, or something to get yourself
removed from the gene pool.
\_ boy, can't everyone just get along, agree on
a friggin' standard so i don't have to be
annoyed by petty differences in execution
every time i use a new box. fer fuck's sake.
\_ There is a standard its called POSIX, barely
anyone uses it. The only shell standard
worth adhering to is Bourne Shell, as
concieved and created by the master in
tribute to one of the finest of languages
ALGOL.
Now about your GNU addition, perhaps you
should check yourself into the Betty Ford
clinic for recovering 31337 GNU/L1NUX
H@0XR5.
\_ I use tcsh because that is what the csua
gave me way back in 1992 and i'm too old
to change now.
\_ Put the following in your .cshrc (or
whatever you pagans use):
exec /bin/sh
One is never too old to renounce the
dark side.
\_ why doesn't bourne shell provide built-in
arithmetic? it really sucks when you're trying
to fix a system without /bin/expr..
\_ bc is usually available if expr isn't.
\_ but POSIX-sh does have it. And POSIX-sh is
basically ksh. So use ksh.
\_ What kind of a man recommends that David
Korn's most hateful rubbish ought to be
used?
\_ What's wrong with solaris grep (either /usr/bin or /usr/xpg4/bin)?
Are you addicted to all that non-standard GNU crap or something?
Damn kids and with thier 311T3 GNU/L1NUX B0X35.
\_ You misspelled 31337.
\_ S00RY.
\_ For starters solaris grep will not descend directory trees.
It is also lacking the -A and -B flags and others. -crebbs
\_ What's wrong with: find /dir -type f -name ... -exec grep {}
....
\_ where's the terminating semi?
\_ creates one grep per file, which is too much overhead.
Use xargs as God intended.
\_ Descending directory trees should not be a function
of grep, that would be stupid and inane and completely
opposed to the UNIX tools philosophy. Take some time
and read "Software Tools" and you will be enlightened.
Old jungle saying if you want to descend trees, use
find & xargs as the gods did in ages past:
find . -type f -print | xargs grep [options] [expr]
\_ With slight updating for correctness (it's what the
original authors would have wanted, had they wanted
their programs to actually work in the general case):
find . -type f -print0 | xargs -0 grep [options] [expr]
\_ older versions of Solaris did not have -print0,
since the original poster didn't specify which
version of Solaris he was using, I had to leave
this out.
\_ is this considered poor style:
grep [options] [expr] `find . -type f -print`
\_ Yes, little grasshopper. If your redirect
results in more than MAXARGS matches, the
command will fail.
\_ follow up from -crebbs unintentionally deleted.
\_ Actually, I intentionally deleted it -crebbs
(it basically said: i'm lazy and i don't really
care about the "UNIX tools philosophy" i care
that grep -r [expr] is easier to type. Though
i certainly don't need to read some book to
get the point being made, regardless of if i
agree)
\_ Software Tools is a book by Kernigan & Plaugher
that explains what the purpose of a "tool"
should be. The purpose of grep is global
regular expression print, it prints out
matching lines from a *FILE* or list of
*FILES* It has nothing to do with *DIRECTORIES*.
\_ The purpose of a tool is whatever i happen
to want to use it for. The primary purpose
of grep is to find something i'm looking for
but don't know where it is. Sometimes that
means i don't know where in a file. sometimes
that means in a directory and sometimes that
means in a directory tree. If i'm just
matching lines in the way you are thinking
i'm probably not using grep i'm usin PERL.
If all i ever used grep for was in shell
scripting i might agree with you.
\_ The primary purpose of grep is not
as you suggest to "find" things
that you are looking for but don't
know where they are. The primary
purpose of grep is "global regular
expression print", it is supposed
to print matching lines from a FILE.
Its job is not to guess what the
linguistically lazy mean. Perhaps
we can enhance the next version of
grep to include a Dieana Troi mode
where it senses what you want to
match and does a big song and dance
to help your find it.
\_ bash and it's default grep sucks.
How comes it's not a mail client too?
Plus, not only should it recursively
grep directories, it should grep
my inbox and mail-folders and also
check my .tar .gz and .zip files
automatically. In fact, you should
use EMACS instead.
\_ if you need this crap, use awk.
\_ awk is for piping $2 to xargs kill -9
\_ grep is grep. If you need more use Perl.
\_ oh please, why use perl, if you need more use JAVA. A
reasonable person uses the quickest/easiest tool available
to get the job done.
\_ And that's Java? Dude, you're sick. |

Make sure to get two separate 17" LCD screens since your eyes
are a non-replaceable asset. Boot up one computer, then another.
Bring up the text file in Notepad and scroll down to the bottom.
On the other computer, start another Notepad. Now you can look
at the left LCD, and key in each line, checking for typos
on the right LCD (are you using an ergo keyboard?). Make sure
to get a comfortable swivel task chair, also, with arm rests.

box at home, but I'm not sure how to go about doing it. I've
got a tunnel to freenet6 from my NAT box, but I don't know
how to config the other systems. Url or other pointers
appreciated.
\_ http://www.kame.net I've set up IPv6, alternately IPSEC over IPv4,
on FreeBSD with it. Assuming they have raccoon (key mgt. daemon)
finished by now, it works great. Otherwise there are plenty of
other IPSEC tools in the FreeBSD ports collection. Kame is real
good for tunneling v4 via v6, and ipf/ipnat work just fine with
it. -John
\_ Thanks for the info. I got the freenet6 tunnel working from my
nat box (OpenBSD) to the 6bone (at least ping6 seems to work),
but now I want to setup my other machines with IPv6 addresses
so that they can be on the 6bone as well. My reading of <DEAD>kame.net<DEAD>
pages is that I need to get a subnet rather than a tunnel. Is this
true? Who should I talk to in order to get a subnet?
\_ No, the subnet is behind either of your kame boxes. The
idea was to let you have ipv6 internal routing, and have
a network-to-network tunnel/VPN as opposed to a host-host
or host-network tunnel or VPN. The idea here is that the
machine (firewall, routing PC) running kame 's internal
interface is your default gateway--to access a machine
on the subnet on the other side of the tunnel will then
be transparent for you, since the kame tunnel takes care
of the ipv6 transport via ipsec ESP. As I gather, kame
also lets you connect to the 6bone, which is a bunch of
people also tunneling ipv6 via v4 (sort of an ipv6
internet on top of the internet.) Mail me for more info.

8/28 How good is FreeBSD's NFS server support? I'm thinking about
switching my Linux machine to run FreeBSD and I want to know
is the wierd NFS problems that I see *all the time* with Linux
will be present in FreeBSD. The machine will only be exporting
a few home directories. Also what is a good (decent performance,
ie not a 3COM nic) NIC for a FreeBSD NFS server? My network is
switched full duplex 100.
\_ FreeBSD's NFS is much better than Linux, especially if you're
serving to other OSen. Also, it's tape system actually works
so if you're making a file server, your headaches will be fewer.
\_ Thanks.
\_ "Weird NFS problems" is not very descriptive. I have used
linux as a nfs/samba server for a medium sized company
of 200 people before and had no problems. -ausman
\_ Okay, here is a list of my common problems:
1. Under high CPU load 1-2 for 15+ min the NFS server
process stops answering. strace says that it is
hung on a lock or a read.
2. Sometimes files become directories and visa versa.
When this happens, only a reboot of the client ws
solves the problem (can't unmount)
3. When secure is specified, clients lose connectivity
to the server intermittently.
4. On big directory copies ~ 1% .nfs* files created.
I never had such problems when my NFS server was a
Solaris machine. I could go back to that machine (SS10)
but I can't afford to good sized disk for it.
\_ Silly rabbit, solaris is for intel.
Can't you afford $70+shipping?
\_ I have Solaris 8 for x86, but I have been told
that PII 400 or greater for decent performance.
Also, Solaris for x86 is mostly geared towards
high-end SMP boxes.
\_ All bullshit. Never trust your source again.
If the CPU is good enough for free*nix, its good
enough for solaris, if you run the same stuff
on it. It's all about RAM. Solaris needs
16-32megs more RAM to be happy than your average
stripped-down linux install. If your box has
128 megs RAM, solaris x86 will perform very well
on it. Even 96megs, if you dont run emacs+netscape.
True, you 'll be most impressed if you have a
multi-cpubox. But otherwise, performance should be
remarkably similar.
\_ I've got a PII 350 and I'll be running it with
128 MB ram. It will be a server only. No X BS.
I like Solaris, but I'm a little concerned about
security. FreeBSD comes with tcp wrappers et al,
while securing a Solaris box is harder (isn't it?)
Anyone know of a good URL where I can get hardening
tips for Solaris (or FreeBSD)?
\_ So.. install tcp wrappers, why doncha?
Or download "sunscreen lite", suns free
actual FIREWALL PRODUCT.
And yeah, there is a web page somewhere
about "hardening solaris", but it sucks.
The proceedure is identical to any other *NIX:
shut down services, remove setuid progs,
check perms on dirs, etc. |

Get your story correct or don't try to sound leet.
\_ As opposed to current solid-state memory

distinguishes between core and solid-state memory nor accurately
explains why it was called core in the first place. Twink.
\_ modern memory technology has not died out slowly or quickly
it's still used all over the place. No one has used core
memory in decades. It doesn't explain why it was called
core, but does distinguish a short-lived, long-dead
technology from a long-lived, still-used technology
\_ Why are you talking about the technology and not
the storage itself?
[a place for twinks on the web: http://www.twinkparadise.com ]_/
core dump, out of core, core map, etc...) core dumps are usually
a result of an illegal operation and can be enabled and disabled.
bus error = i think means misaligned address (obviously illegal).
segmentation fault = there are only certain segments a user
program can read and write from. these access bits are usually
written to the TLB and automatically cause an exception when you
access a segment in a way you're not supposed to.
\_ Get this book, it kicks ass:
Peter van der Linden, Expert C Programming. ISBN 0131774298
\_ you mean you want something more to know about getting a bus
error because you are accessing memory which is "not valid"
(note the quotes).
\_ I was looking for an answer like "This happens when you dont
allocate enough space to an array, or you look past the end of
and array" etc.
\_ accessing null pointers, accessing memory out of
bounds (reading past allocated memory), etc.
Its good idea to check a pointer's validity before
accessing it (like a->foo()).
\_ no, you can get core dumps from lots of uncatched
exceptoins. i don't have to deref NULL or an address
outside my addressspace to get a SIGABRT for example
(which coredumps).
\_ true but the original poster probably wanted to know
common reasons.
\_ Yes, Thank You. Now what is a Bus Error?
\_ As explained above, a bus error is caused
by attempting to read an address/size your
memory bus considers illegal, such as a
32-bit word at an odd address. Usually
caused by utter garbage in your pointers,
due either to not initializing it or
overwriting it with other data. |

\_ thanks, but anything that can work post-facto?
\_ No. This is known as process migration. Some research
OSes (Amoeba, I believe, maybe Plan 9? (don't think so))
can do this, but not Vanilla Unix-Like-OS.
\_ what the fuck? this is NOT called process migration.
process migration is hard because it involves moving
process ACROSS MACHINES. he just wants to talk to the
pty the process was running on. this is an easy problem
and screen solves it. you have to be REALLY stupid to
come up with a reply like yours.
\_ So screen will talk to a process that's already been
left without a tty? What's the screen command for
that?
\_ No, it won't, but if you ran it in a screen window,
your terminal session could die and you could
reattach it later. --dbushong
\_ VMS (a non-research OS) did this 20 years ago. It's no
big deal, just something Unix never picked up.
\_ i think it would be a pretty simple hack to linux to
do this. you need to reattach to the pty side of the
tty, and you need to change the pgroup of the process.
anything else involved? i'm guessing reattaching to
ptys needs a kernel hack. or maybe the mechanism is
already there. in either case, it's a simple hack.

4/26 I have one IP address on my DSL line. I have three computers
on my LAN. I want to be able to telnet into any of these from
an outside IP address. How do I do this? [Question re-phrased]
[Does anyone know of a product that can route more than one domain
on one ip? I know this is possible with virtual hosting. Im trying
to set up three computers I can telnet to on my DSL line, which only
comes with one static ip.]
\_ This question makes no sense. What you've seen is web virtual
hosting but given that your DSL provider only provided you one
IP address you cannot create 3 new IP addresses visible to the
outside world. The best you can do is create a subnet
(192.168.*.*) and have a computer (Linux IPmasq, NAT, WinGate,
whatever) perfrom some sort of network translation. The reason
why web server virtual hosting works is because it's really
using the same IP address but the URL that the web browser sends
to the server hints to which directory to look at. For example,
suggest NAT software in which the telnet remaps are
if I have a web page at http://www.dnai.com/~jondoe I can request that
dnai set up virtual hosting so that when a browser asks for
http://www.jondoe.com it will actually return to the browser
http://www.dnai.com/~jondoe instead (although the person surfing the
web can tell this). How that's done is simply adding a DNS entry
and reconfiguring the web serer. But most services don't do
that. You cannot map a host name to an internal firewall's IP's
port. For example, you cannot create a DNS entry called
<DEAD>ssh-to-scotch.berkeley.edu<DEAD> to map to <DEAD>scotch.berkeley.edu<DEAD>:22.
If you want to be able to telnet to your three internal
computers protected by the firewall, you can setup portforwarding
which is supported by many OS's. So you can have a port listenig
on port 1234 of your firewall so that when you do a
> telnet <DEAD>mydslline.com<DEAD> 1234
it will send all the packets to your internal computer.
\_ I know Win2K server can do this, because I have it working now
with your situation. Incidentally, I asked the same question
on the motd half a year ago and the responses I got were
the equivalent of "huh, fux0r?" and "fux0r me".
\_ Win2K isn't magic - any NAT software can do this, but
you'll have to map different ports to different hosts
(i.e. telnet NAT 23 goes to host a, telnet NAT 123 to
host b, telnet NAT 223 to host c)
\_ Yeah, but Win2K has it nicely dumbed down. Please
suggest software in which the telnet remaps are
easy with the matching OS name. Thanks! =)
\_ uh, the "product" that can "route" more than one domain to
one IP is called "DNS", and that doesn't stand for "Digital
Nervous System" you stooge. -tom
\_ tom, as you've pointed out, the question has some problems.
Nevertheless, you can set up Win2K server to route
telnets to your single DSL IP to an IP in your internal LAN.
\_ the question is stupid and will be deleted in about 20 minutes.
\_ Don't be a doofus. The guy just wants to know how to do
NAT. Just because he doesn't know the exact right question
to ask doesn't make it a stupid question. If he knew
what NAT was he probably wouldn't have had to ask how to
do it.
\_ No he doesn't you doofus. You cannot solve this with
NAT, because he stated he has ONE IP ADDRESS globally.
You need a reverse-proxy, or plug-gw, on a
real operating system.
\_ A real OS, NAT, and DNS and he's fine. WTF's your
problem? _I_ wasn't the one talking about win2k.

you submit your e-mail or name. Now the site has
associated this information with your cookie. Frankly,
I don't care.

in Linux) to boot up in single user mode and change the root
\_ You probably mean "RedHat Linux". Sane distributions like
Debian will not just give you a free root shell when you
boot to single user mode.
\_ if you can pass the kernel the "single" parameter,
you ought to be able to pass it "init=/bin/sh"
instead.
\_ are you talking about a buffer overrun exploit here?
password? If not, how in the world do you install a new OS?
There's no floppy drive and no CDROM drive. The only thing that
exists is a NIC but I thought you at least need a boot floppy for
an FTP/NFS install. The machine has IRIX 6.4 btw.
\_ No... if i remember correctly.. you don't need a boot floppy
the hardware has a built in booter for doing nfs/ftp installs
or you can get a cdrom for it :) or i could be wrong..but i
remember doing clean installs on boxes with no cdrom/floppy
\_ Are you talking about changing the prom password? It is
possible to boot a miniroot and change the OS password. You
will need a cdrom or a network connection with a SGI (the
cdroms, I believe, are in EFS format) |

\_ what escape key combination have any of you found to conflict
the least with existing programs? C-a seems to be used quite
often. Also, is there a way to make the new shell start with the
same terminal type as the shell that invoked screen (it always
thinks the terminal type is screen, but I'd like it to be vt100
or xterm, whichever one I started screen with).
\_ I use CNTRL-D: alias screen="screen -e^Dd". For the term
type I think that it is -T <type>. Just use a function:
screen () {
if [ -z "$TERM" ] ; then TERM=vt100 ; fi
/usr/bin/screen -e^Dd -T "$TERM" "$@"
}
\_ Wow.. this person has scary ways of doing things that
will tend to break. Please don't listen to them. Use ^O.
Set it in your .screenrc. Set your term to vt100 in your
.screenrc. You'll be happy.
\_ What's wrong with Control-D? It prevents you from
accidentally logging out as a side effect. I prefer
xterm to vt100 since meta works correctly for
emacs -nw when term is set to vt100. Yes I mostly
use xterms.

4/5 Let's say I have a big NT server running and I want my UNIX box

(kinda like reverse NFS)
\_ samba (both client and server exists)
\_ get your terminology straight. You want the UNIX box to
ACCESS the files, not "share" them.
\_ Well, first: you really _want_ to do it the other direction.
If you can't then: installing samba will get you ftp-like
access to those files. If you want it to appear as a transparent,
mountable filesystem, either run linux (which as an fs module
for this), or use Sharity (Light or otherwise), which let's you
fake samba mounts as NFS mounts: http://www.obdev.at/Products

4/3 Will NFS and NIS/NIS+ clients work fine from behind a router running
NAT software? Did anyone try this before? -akopps
\_ If the machines involved are all behind the NAT router, sure.
If the NFS server is outside the firewall, not normally. They'll
all look like the gateway machine to the outside server; if you
want all your NAT-protected machines to have identical access,
you could grant it to the gateway and that might work. NIS
is probably no problem, NIS+ probably won't work (it wants to
match a hostname to a DES key, which it won't be able to do for
your NAT hosts). -tom
\_ nfs, nis with clients and servers on opposite sides of the nat box,
yes. As tom says, you need to grant nfs access to the nat box to
grant any access to the nat clients. NIS works again, so long at
the one nat box is able to access NIS. nis+ hasnt worked yet.
having a nis+ replica server with/without nis compatibility mode
on or behind the nat box may give you want you want. Lemme guess,
this is for the ocf? --jon
\_ Yes this is for OCF, we are considering various options for
the new lab. I think if we run our NIS+ servers multihomed
with one interface connected to internal network and another
to internet this could work. I still think this fancy setup is
not worth the hassle. Lets hope we get enough money for campus

3/24 How do I add new users to a LDAP server (I'm using openldap)?
Right now I have the rootdn, but I would like to have a couple

\_ man ldap
\_ people like you are the reason "unix" should be spelled with
a ch and an e. E-U-N-I-C-H-S.
\_ "Unix is ready for the desktop" == "Unix weenies aren't
ready for the human population"
\_ You stupid fuck, it's in my man pages. Just because you
lack man page fu doesn't mean all of us have shitty man
pages. Like I said, man ldap. Get better pages if it isn't
there but don't insult your betters. It only shows how

close. You are not only a stupid fuck and an asshole,
but your smearing "alot of unix people" in one nice big
easily smearable group is ridiculous. If providing the
only real answer makes me an annoying asshole, then so
fucking be it. --annoying asshole who gave right answer
\_ man ldap on Sol2.7 didn't have anything about adding users.
Anyone have a better idea. I already looked on http://www.openldap.org
and they explain how to do ACLs, but not how to add users that
the ACLs apply to. It seems like I'm missing something obvious.
\_It's my _guess_ that OpenLDAP doesn't have a cool like app or
GUI to create users (unlike Netscape or other directory servers).
But since LDAP users are just entries in the directory, the
common way to do it is to use your favorite text editor to create
a LDIF file and use some utility to read the LDIF and place the
entries into the directory. (LDIF is also much better for adding a
lot of entries (users), you'll be sick of the GUI really fast.)
See http://www.openldap.org/faq/data/cache/182.html for some more
info. You may need to dig into the schema and the documentaton
for the LDIF format (on web somewhere) if you want something
fancier. -lcddave
\_ Yeah, openldap doesn't have a nice gui to add data, but
I don't care about that. I'm accessing it all via JNDI
from a set of servlets. The part that I was missing is
that any valid dn can be used as a user. I just need
to add the userPassword field for that record.

\_ Short answer: having a bunch of machines with same config and some
'clustering software' that makes it so these machines are all
redundant backups for each other and also share horsepower for
things like cpu, io, etc. There's more than one type of clustering
and quality, price, features, etc vary widely between vendors,
versions, etc, but this is the gist of it for laymen.
\_ Mainstream products that do "clustering" are almost
always failover systems. Parallel processing is much
rarer. Sun and Veritas both have clustering products.
-brianm
\_ clustering >> failover.
a cluster normally handles "failover", but a failover
solution does not neccessarily do clustering.
A [group of] system[s] that is purely a "failover system"
is NOT a "cluster"
\_ Guys, I was trying to just get the main idea across and
not start a lengthy shitfest over the details. Thanks.
\_ For me clustering involves non-trivial degree of communication
between the nodes, ie tightly-coupled cluster vs. a simple
server farm. Most people use the two terms interchangeably, though.

2/24 Security Questions. I was reading about some strategies for defeating
DDOS on http://www.sans.org/ddos_roadmap.htm One of thier points
was:
* Unless an organization is aware of a legitimate need to
support broadcast or multicast traffic within its
environment, the forwarding of directed broadcasts should be
turned off.
I'm using my linux box as a router, and I want to know if this
means that I should do something like the following:
ifconfig eth0 -broadcast -multicast
Another point was that RPC services should be disabled on
border systems. My understanding was that a border system
shouldn't server files via NFS, but mounting was okay. If I
need to mount directories, should I be firewalling the RPC
port?
\_ -broadcast means something other than 'forwarding directed
broadcasts'. In fact if you actually turn that off you may
break important broadcast based protocols like ARP. If you're
on a linux box you really want to do something more like:
echo 1 > /proc/sys/net/ipv4/icmp_echo_ignore_broadcasts
-ERic
\_ Thanks. Do you know if this works with 2.0 kernels or is
it just 2.2 kernels? Also, I'm assuming that -multicast
is okay.
\_ Doesn't look like 2.0 kernels have the option. I'm assuming
you dont need multicast for things like MBONE so yeah
just turn it off too. -ERic
\_ I'm not using MBONE at home. I only have 384/128 ADSL,
so its just not fast enough. I guess I will have to look
at the 2.0 kernel compile options to get something similar
to ignore broadcasts feature.
\_ you'd probably do a lot better to just set up a
lot of ipfw rules to block out any traffic you dont
really need. -ERic |
