8/29 How do you connect to the internet when you are travelling?
(work or vacation)
\_ i find the nearest university, go into their main library, and
can usually use the computers there.
\_ Vacation? That's what vacation is for. *Not* connecting to the
net. Bring a book. Not a technical manual. A real book. Enjoy.
\_ The internet has this useful stuff called 'information'. It's
often useful to have this 'information' about the place that
\_ I don't. In fact, I avoid being connected at all when on vacation
\_ McDonald's parking lot.
\_ they have wi-fi??
\_ duh. would you like fries with that?
\_ For work, I usually make sure that I stay at a place with
broadband. Barring that I use one of my isp's nationwide
callin numbers. Usually in foreign countries I just buy a
short term card that allows for dialup access.
When I go on vacation I leave my computer behind.
\_ If I'm on vaction in the states and feel a need for an email
fix I just drop by a library. Baring that it is pretty common
to run into an internet cafe where you can check your email
for a couple of bucks.
you're travelling to, especially if you're not a native of the
area. |

8/26 I get my DSL from SBC (which uses PPPoE), and when I connect the
DSL modem directly to my freebsd machine it connects fine (using
/usr/sbin/ppp). But when I go through a Linksys router, to
share our DSL line with my other roommates, I can't connect
anymore. Is there something special I have to configure on my
machine to be able to connect? Thanks.
\_ I imagine the Linksys router "hides" the PPPoE end of the DSL
line, i.e., all your computer should care about is turning
on the DHCP client (any PPPoE thing should be off).
\_ How do I do that? (I'm a newbie still)
\_ I'm a FreeBSD newbie, but I imagine it's "turn off
/usr/sbin/ppp" and "turn on the DHCP client". There
should be a FreeBSD FAQ on that.
\_ 1. Make sure your router is actually doing PPPoE (ie, verify that
your roommate can connect to the internet.)
2. dmesg|more and look for your ethernet device, possibly xl0
or something similar. Edit /etc/rc.conf and replace any
ifconfig_xl0 lines with ifconfig_xl0="auto", which will handle
the dhcp client for you.
3. If anything goes wrong, mail your friend who helped you set up
your machine.
\_ I actually just turned off ppp and then ran dhclient, and
everything worked out fine. (except that now I lost my
ability to host a webserver since I don't have a real IP
anymore).
\_ All routers like this I've seen allow you to route ports
or port ranges to a specific client behind it. I run a
webserver behind one of these routers just fine.
\_ My God, they let people like you on the net? That's shockingly
dangerous. Do you make sure to respond to all spam and open all
attachments from Tiffani?
\_ My God, the did let me on the net! Are you shocked? |

8/25 Do people actually verify md5 sums? I recently ftped a linux
distribution iso and installed it. It seems to run fine. Then
by chance I run md5sum on the image and the first disk failed.
Is this just some transmission error or something more sinister?
\_ freebsd ports do this automatically. You should probably try
pulling the image again and rechecking. it could be truly sinister,
it could just make your system unstable down the line. look at it
as a strong litmus test.
\_ I already did and the new download passed the check. I am
going to reinstall the whole thing. But if it is the installer
itself that got corrupted maliciously, should I worry about
all the partitions of my disks and all the disks that was
mounted when I did the installation? That would be really
too much pain.
\- based on the strength [sic] of the tcp checksum
and the error base rate you can figure out how often
you can expect an undetected tranmission error.
we made some calculations a few years ago and when you
started shoveling gigabytes around you needed to start
worrying about these and doing some kind of stronger
application level checksumming. lately i havent done any
measurements to see if the base error rate has gone down
[or up say in wireless or whatever] and what the new
expectations might me. however i certainly am not sur-
prised to hear large iso or tarballs coming over long
paths arrived frayed at the edges. if you are interested
in techical details and have a general familarity with
tcp, you can mail me. any discussion of this on say
NANOG? --psb
\_ Google, as a result of their work, keeps track of
these numbers. Look up their research.
\- oh yeah i remember asking the google folks
if they do higher level checks, what chksums
they ue etc as the copy around parts of the
they use etc as the copy around parts of the
cache. do they "publish" these things anywhere?

8/26 I've ended up with two dsl lines at my house till the
end of the year or so. I would like to run some sort
of routing protocol so that I can maximize my bandwidth
by using both lines. I'm not sure how to go about setting
this up, any pointers/ideas? I'm running *bsd if that
makes a difference. tia.
\_ there are several ways to do this, but I doubt any of these
features exist on a desktop OS. You need a router in between
your PC and the two DSL lines. Things such as multilink PPP,
LACP (link aggregation), and other load balancing schemes can
make use of two physical links. PBR can work, but it's really
overkill. A link layer protocol can do this in a much
simpler and stable fashion. -cisco guy
\_ for the most part, not possible unless you do some very
fancy policy based routing... not worth the trouble.
\_ Okay, would it be possible to say just route vpn
traffic on one dsl line and http/ftp traffic on
the other?
\_ and make life, support and debugging a living hell?
What if one DSL line goes down? Nevermind the fact
that you are probably going to get fired by your
company for compromising their vpn/intranet
And you're going to go thru the effort to set that
up and use it for 3 whole months?
Besides, why did you let SBC/PacBell screw you like that?
\_ why would my having two dsl lines compromise
my company's security? (I own both the lines
an neither is directly connected to my company
except when I have a vpn up)
\_ Because you are trying to set up a split tunnel VPN
I am assuming you are doing that because you are
bright. If you are doing it for some other reason
they you really have a chance to get into trouble.
\_ I guess I should clarify. I have one machine
with multiple outbound connections. It acts
as a firewall/router for the other systems
at my house. It doesn't (and can't) run the
vpn software. What I want to do is to have
this machine route all the ipsec traffic
from my other machines out one interface
and route all the other traffic out the other
interface. When the other machines are using
a vpn they run in full tunnel mode so I don't
have to worry about debugging problems from
using a split tunnel.
I know the quick and dirty way to do this is
to use a bunch of static routes but I wanted
to see if there was some way that I could get
around using static routes and just route
pkts based on whether or not they were ipsec
encapsulated or not.
\_ Sure, no problem. Ignore the nay sayers. They have different
IPs so assign a different domain or hostname, etc to each one.
Changing DNS later is trivial. You won't get fired anymore
than you would have doing what you're doing on one line.
Apache, sshd, and many other common servers can be told to
only listen on a particular ip/port. Unless you've got huge
traffic on some service you won't notice the difference but
it's a good learning experience.
\_ okay.. explain this some more then. what you're describing
still requires policy based routing to work. the machine
may set the outbound ip to one on the second dsl line
but it will still at least try to go out the first line
since that is the default route. on top of that, the
isp of the first line may drop the outbound packet since
it's not one of their own. -shac
\_ Static route to vpn server. It's the only place he
wants that line to go. You can call that 'policy
based' routing if you like. I'm not going to quibble
over terminology. |

8/11 Interesting news blip - McDonald's offers free WiFi in select
restaurants in the Bay Area, New York, and Chicago through the
month of August. For locations:
http://www.mcdwireless.com/locations/MCDw_loc_SF.html
\_ Why would anyone want to compute or spend any additional time
in such a noisy and unclean place as McDonald's is beyond me.
Specially, considering lots of coffee shops are considering getting
WiFi too.
\_ TMobile offers WiFi now in select locations... I think they
are partnering with Starbucks and Borders. |

8/10 Does anyone know how to force Win2k to use shared WEP authentication
instead of open auth? WinXP has a control panel to enable this, but
I can't seem to find the Win2k equiv.
\_ Check the card settings (control panel->network connections->
whatever card->properties->card configuration near the top.) If
that doesn't do it, I've seen manufacturer card tools take care
of dealing with encryption options (Cisco, Linksys, Netgear and
Lucent all have their own software that comes with the drivers.)
Check the manufacturer page for downloads. -John
\_ WEP is only to protect the privacy of your connection, right? Is
there a way to allow only certain users to connect to your wireless
access point? If someone gets a hold of the WEP password, they can
share that with anyone, and anyone can get access, right? How can
a wireless access point be configured to allow access to only
people you want?
\_ PPPoE or something like that. You can also use the
network name in 'closed' mode (i.e. non-broadcasting),
although if you want serious security, you will run ipsec
over your wireless links. -John
\_ Some wireless APs will do MAC address or other filtering
but that's still not real security. |

8/4 I am a cheap bastard who knows RF, but doesn't know jack about DSL.
What exactly is a dsl filter? what rolloff frequency is needed?
can i just make a rc filter or pi filter with a pair of modular jacks,
or is it an active filter of some kind? i already stfw'd and all anyone
wants to tell me is where to buy one.
\_ What are you trying to do?
\_ I think he's trying to steal DSL off his phone line or something
like that and his time has zero value but I'm just guessing.
Think of Qusay's children!
\_ no, i'm paying for dsl, and already have one filter for
my phone. i just want another filter for my other phone
so it doesn't interfere with the dsl or cause odd noises
on the line. given that i spend alot of time making rf
filters anyway, this filter might well take me ten minutes
to build if i know what frequency i'm trying to filter.
since a new filter is about 15 dollars, i would have to
value my time at 90 dollars an hour for it to not be worth
my time to make the filter. since i'm a grad student, my
time is worth considerably less than that.
\_ but you've already spent more than that time Sing the FW
and typing stuff on motd. and since you already "know RF"
you aren't even learning anything.
\_ Doesn't SBC give you like 3-4 of the filters anyway?
I seem to recall having many extras, send me an email
if you're local to Berkeley and I'll bring one in - mds |

8/4 To follow up my post a few days back, 3com says the 3CRPAG17 is the
only 802.11g card on the market with a retractable antenna. (patents)
Unfortunately, this card uses a new 3com propriatary chipset, the
name of which isn't available until the card starts shipping at the
end of August. No Linux drivers will ship with it. She said linux, BSD
and OSX drivers will all probably come out later. I'll wait.
\_ Of course *nix drivers won't ship on day 1 on a brand new product.
\_ Someday that will change.
\_ You mean they won't ship at all?
\_ Yeah, clearly Linux and BSD are going nowhere.
Windows is the best OS. Just ask the virus writers.
\_ Just living out here in the real world. 'Best' in
what way? Viruses or no, it's what sells. It's what
they make drivers for first and always. Any other OS
and you're waiting, maybe forever or rolling the dice.
When your mom is running *nix at home and your work-
place converts the recptionist, HR, and finance to it,
lemme know.

8/1 Any recommendations for an excellent 802.11 cardbus card for linux?
\_ Netgear MA-401. Works perfectly on FreeBSD w/ my dell laptop.
\_ Thanks.
\_ Oh yeah, if you order before early September (I think)
from http://NewEgg.com there's a $10 rebate.
\_ Cool, thanks again.
\_ That card is 802.11b. Any recommendations for 802.11g,
or is "g" overkill or not standardized yet or something?
\_ Linksys 54G is ok--the one I have came out before the
standard was finalized, and FreeBSD <5.0 doesn't support
the card. -John
\_ Does the antenna detach from the card w/o taking the card
out of the PCMCIA slot?
\_ go g if you can afford it. it's backwards compatible and
will be much faster when it becomes standard. of course,
if you just have dsl and use the wireless in your home or
in internet cafe's, any speed above 100KB/s is not needed.
\_ Who has only 100kb/sec on their broadband?
\_ He said 100KB/s, not kb. But a large portion of the
dsl lines get ~150KB/s.
\_ Does any companies other than 3com make a 802.11g CardBus
card with a retractable antenna? I can't find any info on
Linux drivers for the 3CRPAG175
\_ I get cruddy reception with both of my MA-401. The built-in
on my laptop gets better receptions. |

7/28 I currently have a standard SBC DSL for 49.95/month. Their site lists
this has 384K-1.5M download. I'm thinking of upgrading to their 59.95
package that claims 576 - 1.5M download. Anybody done this switch?
I'm thinking if this is a gimmick or they can really guarantee that
speed. DSL speed depends on distance from CO. If they can suddenly
crank up my speed, that means that they're currently putting caps
on my bandwidth? I'm trying to avoid switching and then not seeing
a difference and have to spend a lot of time trying to switch back.
Thanks.
\_ dump SBC and go with http://speakeasy.net.
\_ heck, at work we get 4 Mbps easy. It's upload that's the problem.
of course we pay work prices, ~ $150/month.
\_ Sucka. SBC DSL is $29.95/month
\_ ???
\_ their 1.5M/256k "deluxe" service is $39.95 with 12-month
contract. i think the offer ends 9/30 or something. basically
$20 off any service plan w/ 12-month commitment. speed is
a tiny bit slower than my old comcast cable service, but
i am happy to be shed of the comcast "thou shalt also
subscribe to our cable tv or be fuxxored" policy.
\_ What about current customers? --dim
\_ The switch doesn't work in all cases. If they can't find
an open circuit in your co that meets the distance req.
they will tell you that you can't be upgraded.
\_ This whole broadband thing is still a really immature technology.
One day you'll get data service the same as phone service and
none of this BS about how far you are from the CO or open
circuits or different speed charges, etc. It'll just work.
Until then this whole thing is a big hack.
\_ This whole politics thing is a really immature society.
One day, you'll get world peace and equitable allocation
of scarce resources, with none of this nonsense about
nationalism or different ethnicity. People will all just
get along. Until then, this whole thing is a big hack.
\_ Network bandwidth will continue growing until it becomes
truly ubiquitous. Clean water, food, and land will not
until we can easily leave this planet or a few billion
people get wiped out quick and clean.
\_ Electricity will be too cheap to meter! This was the
slogan of the nuclear power industry 40 years ago.
\_ Maybe you missed the part where we haven't built a
new reactor in decades?
\_ Maybe you missed the point.
\_ This whole dating thing is still a really immature sociology.
One day you'll get date service the same as sexual service and
none of this BS about how far you are from third base or open
relationships or different STDs, etc. People will just screw.
Until then this whole thing is a big hack. |

6/17 Is switching to Dvorak worth it? And, how is it for programming?
\_ I've read one article (in 160 I believe) that said that
it really doesn't improve typing speed that much. Some friends
switched to it and liked it, but also noted that their
typing speed on QWERTY slowed dramatically.
\_ I did it for about a year, and the benefits/drawbacks were so
minimal that I reverted simply because it was a pain to switch
the layouts when someone else wanted to use the computer.
This was mainly an essay-writing time though, not coding.
\_ don't forget about keyboard shortcuts.

typing all over again. However, it's really worth it. I use

6/1 Some idiot where I work brought in a netgear router and plugged it in
and broke DHCP for a whole bunch of buildings. Is there a way to
prevent idiots from breaking DHCP? I know that win2k has some domain

\_ The idiot is the Dean of Students. I work at a high school.
If we had all managed switches, I could have found him easily,
but we have a lot of old infrastructure, so I could only nail
it down to the bulding.
\_ Let me also add that this idiot also starts blaming others,
saying that he had that router for over a year and that we must
have changed our configs or something... so if anyone were to
get fired, it would probably be me before him... so social

something stupid, else you would have to fire damn near everyone.
(The same help-desk people were constantly bringing the network to
a crawl by Ghosting images over it, even though the computers they
were ghosting to were in the same room as the ghost server).
\_ Sure you can. Let's start with rule #1: do not plug any
device into the network. or you're fired. simple, see?
Rule #2: always ghost over a private network or use a
cross over cable between the two hosts. or you're fired. works

5/22 When I was learning the basics of the network, I have always thought
that one IP address per NIC card. For machine that has multiple
NIC, it is essentially a router... But the other day, my company's
system admin just done something i don't quite understand: he
assigned multiple IP to a computer (running windozes) which only
have one NIC. Can someone explain to me how does that work?
Thanks
\_ They're just aliases. The NIC can listen for and respond to
multiple IPs. Most modern OS's can do this. No magic.
\_ or it can be multiple virtual sub-ints..
\_ this is where i don't understand... where can I find out
more?
\_ 'man ifconfig' is a place to start. -John
\_ STFW
\_ Given that you have multiple web sites which resolve to
different IPs in your subnet, you could host them all on one
Windows computer, assigning one NIC the different IPs of your
web sites. (this is just one way to do it ...) |

5/22 To people with TCP/IP clue: A friend of mine has a wireless router
at home (D-Link's DI-614+, but there doesn't seem to be much in
the way of useful model-specific docs around of any but the "here's
how you click a button" kind). The thing comes with a built-in
capability for firewalling, "virtual server" (i.e. port forwarding to
a specific LAN machine, set up by port number on the external
interface), etc. At the moment, we can't get traceroute (from local
machines to the outside world) to work whatsoever; it shows the first
hop to the router, and doesn't give anything past that. I've tried
allowing all ICMP&UDP traffic in both directions, but to no avail.
Presumably I don't understand the traceroute mechanism
well enough, and am missing something. Any suggestions?
\_ I had this problem with an SMC router. I have reported this to the
manufacturer. Later, they have come up with a firmware that fixed
this problem. Lots of those home broadband routers have very lousy
TCP/IP implementations, so the problems like this are expected to
pop up all the time.
\_ That's, err, good to know I suppose. I'll try that route,
thanks. -op (other advice still solicited though)
\_ Not an expert, but I believe traceroute is simply a series of pings
with a timeout short but increasing timeout-- so you ping http://yahoo.com,
and router1 responds but router2 does not because the timeout has
elapsed. For the second ping, you increase the timeout so router2
replies but not router3. And so on. Short answer is that your fw
is most likely preventing the ICMP echo from getting back to your
PC.
\_ you're right...you're not an expert.
\_ hello cranky asshole router guy!
\_ CARG does have a point, he indicated that ICMPs are
\_ CARG does have a point, op indicated that ICMPs are

\_ it's also inaccurate; traceroute is not a series
of pings. -CARG

\_ timeout or ttl (time to live) based on number of hops
\_ That's just the micro$oft "tracert" implementation (or rather,
a distorted account thereof); most others use UDP. But in any
case, see below; this is probably not the problem. -op
\_ The default setting on the router is probably to filter ICMP
echos.
\_ Yes, but I'm fairly certain I put in a firewall rule to allow
all ICMP traffic in both directions. -op
\_ In the Advanced->Filters menu, try setting ICMP type 11 to always
oops, 8 _/
In the Advanced->Firewall menu, set to allow all ICMP types

dialog's "protocols" dropdown, I found out I'm several firmware
updates behind. However, the latest firmware update, even though
labelled "fixes traceroute issue" on D-Link's site, still
has no ICMP option there and traceroute is still not working. -op
\- hello has anyone seen the following "traceroute problem":
on a couple of solaris boxes, all of a sudden something
weird happens to the tcpstack and it never sends ICMP Port
UnRchables back to you? So any udp traffic is silently

4-port hubs, which is another possiblity... one with a coax port
on it... You could also find some old 386's with 10-base T and

4/16 hi motd. I have a home network of Windows computers each getting
DHCP addresses from the ISP, and the IPs change often and are on
different subnets (go figure). What's the best way to share files /
a printer between the home PCs? Putting two NICs in each computer
is a hassle, a NAT gateway would leave each PC with private IPs, and
adding a static route over a larger ISP subnet would prevent access
to some remote hosts. Thanks.
\_ use Rendezvous / link-layer zero-configuration IP addressess.
\_ Why not use a NAT gateway? Assign unique private IPs to each host,
and NAT them to the internet.
\_ Because this house is full of Internet gamers
\_ Don't be a wimp. Put in a second NIC and stop being a baby about
it. You just named all the ways possible and then said you don't
want to do any of them. If it's too hard to add a $10 NIC and a
$20 hub to make an internal net then you have no business having
more than 1 computer. I have no sympathy for the lazy.
\_ Wouldn't it have been nice if DHCP clients could also have
a static IP on a single NIC? -op

foo is lacking. I've tried man dhcp|ifconfig.

4/14 Is there any point to ARP in a pure switched environment?
\_ If by purely switched you mean you have the ability to send/
receive raw ethernet frames and not use the IP stack, then yes,
there is no need for ARP.
\_ I mean when you are in a switched rather than shared
ethernet and everything is going down the wire to the
switch anyway because you have a defaultroute.
Doesn't the switch and its arp table handle getting
things to the right place, rather than the host making
any decisions?
\_ ARP is the name map between the MAC layer and IP
\_ initially the host's arp table is empty. You have a
default route but that's just an IP address. You still need
the default router's MAC address. The sequence of events is
roughly:
1. host tries to ping XYZ
2. host tries to send the packet to default router but
doesn't have the default router's MAC address.
3. host sends ARP packet out onto the wire.
4. default router picks up the ARP packet and responds.
5. host now knows the MAC address of the default router.
6. host sends the ping packet again to XYZ with the
destination MAC address that of the default router.
This is the reason why the first ping packet after bootup
always fails. You can get around it by statically adding
the default router's mac address to the host's ARP table.
But that's not recommended. -cisco guy
\_ like I said, ARP is the name map between the MAC layer and IP |

cable modem access if I don't have cable from them. How can they
get away with charging $20/month more than DSL?!? Has anyone called
to yell at them and gotten good results?
\_ Vote with your feet.
\_ damn right I will! Just gathering info first, so that I can
make the most informed decision... -OP
\_ Say you want basic cable for $9.65/month, but you don't want
to rent the converter or remote. See if that works.
\_ Do you mean that the hassle of giving me cable without the
rentals will make them give me the original price back, or
just that if I'm going to pay the extra I might as well get
the cable? -OP
\_ I mean they'll give you your original rate (last I heard
it was $46/month) if you get Basic Cable. I understand
it's $60/month without cable TV.
\_ They can't. They jacked up cable tv prices so I've got satellite
now. It's cheaper and better. If they jack my cable modem rates
I'll switch that too. It's a semi-open marketplace.
\_ less open than it was last year. Thank you FCC.
\_ I received that notice as well. They said that if I sign-up for
cable my internet montly fee will remain the same (~40$) and my
cable will cost $6/month for the first 6 months (with no setup or
cancellation fees). So, ~$50/month for cable and internet still
seems better than DSL since my cable connection is faster than
T-1 for download.
\_ I did that calculation too. Are there any surcharges (fees,
taxes, equipment rental, etc.) on the $6/month cable?
\_ I just called them, and when they say "basic cable" they're
not kidding. You only get the local channels (that you
would normally get for free via broadcast) plus C-Span,
a few other government access channels and sometimes they
include the Discovery Channel. The next plan up (which
all of us would consider basic cable, i.e. CNN, etc.) is
$32/month to $42/month depending on digital vs. analog,
location, and probably how much they think they can extort
\_ In oakland, with taxes and fees, analog is $42/month.
digital is more. cable selection around here sucks.
find something else.
from you, etc, etc. So, if you want to keep your cable it's
still cheaper to get the $6/month for a total of $48.95, or
splurge for real cable for a total of $74.95. I'm thinking
of choice 3: spend the extra $6/month for basic, and when
the cable guy comes just give him $20 to hook up the
additional channels. Last time a cable guy was at my place

3/10 My AP times out after 5 minutes. What gives? [ rehash, motd was wiped ]
\_ I have this same problem with my linksys cable modem hooked to
my netgear AP (no wireless in use). The problem seems to come from
my cable modem (I didn't have this problem when I rented a motorola
cable modem).
\_ I think it's the AP, not the cable modem. The only place I've
had this problem once, with the open access point on a dsl
modem (netgear 814something) but never on anything else
(airbears, airport, linksys, d-link, wired linksys, etc.)
If I had to guess it'd be the inactivity of the nat connection
expiring and being delisted. -dwc |

that once the listen port (i.e. port 80) recieved a connection request
I remember I used to spawn a different thread at a randomn port to

firewall that blocks all the connections from port 1024 and up,
would this proxy thingy still work? or Firewall's block is
directional? any pointer on how this thingy works? thanks

2/14 I finally got around to setting up SPAN (makes your Cisco switch sort
of act like a hub) so that I can monitor my traffic. Ethereal kind of
shows which protocols are using most of my bandwidth, but doesn't
print pretty graphs. Also, I'm mostly interested in finding out which
hosts are using most of my traffic. Are there any Ethereal-like apps
that do this well? Pretty graphs are a major plus.
So far I've used TTT, which is kinda crappy.
\_ leaving span enabled all the time isnt a great idea, esp if you
are spanning the whole switch to one port, not just mirroring
a port or a given vlan.
\_ why isn't it a good idea? intrusion detection systems depend
on traffic monitor 100% of the time. SPAN is a wirespeed
feature on the catalyst family. Packet replication is done
by HW so there's no performance degradation. You can also do
fancier stuff like use VLAN ACLs to replicate all traffic
in/out of a VLAN and analyze that traffic. There's more
commericial software that analyzes netflow tables though. You
can also setup the router/switch to export those netflow
entries. -cisco guy
\_ not all switches behave the same when spanning.. relying on
spanning a whole switch to a single port is a ridiculous
idea w/ large switches that can easily handle more traffic
than any 1 port.. for example, a 6500.. the smart thing to
do with an IDS is to only span against the inbound/outbound
port rather than the whole switch. if you rather watch
the whole vlan then you splice down and mirror 1 vlan / port.
the easiest way to defeat an IDS is to overload its span
port or overload the IDS. there have also been many bugs
that are triggerred by sustained spanning on shitty (low
end) catalyst switches. for a "cisco guy" i dont think youve
worked with spanning very much on the ios based switches.

\_ Dynamic IPs don't work with cable modem.
\_ if the router does port forwarding (and most do), yes, you can
run a server easily enough. or you can go for the dynamic IP
addresses and use something like dynamic DNS.

most don't cost.
\_ I'd do the static IP. A zillion small businesses run just fine with
a single static IP. You can too. Dynamic dns gives a lame and
highly unprofessional look to your domain.
\_ While I suggest going with static IP, you can side-step
the unprofessional look by making your FQDN a CNAME
to your dynamic name (e.g., http://www.domain.com CNAME <DEAD>host.dyndns.org<DEAD>)
\_ For the clueless (like me), how would I do this?
\_ 1) Set up a http://dyndns.org host (e.g., <DEAD>host.dyndns.org<DEAD>)
2) Register domain (e.g., http://domain.com)
3) Make http://www.domain.com an alias for <DEAD>host.dyndns.org<DEAD>.
You can use http://UltraDNS.com.

1/29 I want an IPv4 address block (/24 is good enough). ARIN charges
$2,500 in addition to regular membership. Any other cheaper places?

a good reason, esp if you are a hicap customer. recently i had an
isp route a /24 for an additional $100 on top of their normal
monthly charges for a T1.. which was about $1500... of course the
cost for that T1 varies HEAVILY by the provider (big guys like
Internap charge much more than cut-rate ones) -shac
\_ ask your upstream ISP
\_ How much does this go for?
\_ Varies dramatically by ISP based on the total service
package. My company has 64 addresses and a 32 rack cage for
about $25k/month. YMWV.
\_ Also, your ISP might charge you to manage that /24, no?
\_ i get 14 IPs on 1.1 SDSL for $179. supposedly they'll give me
more IPs but i haven't quite needed them.
\_ Do you want to own the block? This is necessary if you want to
be portable (i.e. change upstream ISP without renumbering) or
multihomed (multiple upstream ISPs). Most ISPs will offer at
least a /24 along with real connectivity (T1 or greater) at little
or no cost, shac's figure of $100 on top of transit sounds
reasonable. In order to obtain a block from ARIN, you have to
jump through a number of hoops which can be a pain. I strongly
suggest you get someone who has successfully obtained IP space from
ARIN in the past to assist you with this. Their is also a gray
market for IP address space. You'll still have to obtain an AS,
and the transfer will have to go through ARIN, RIPE or one of
the other regional equivalents, but this is often cheaper and
more expedient than going directly through ARIN. -dans

\_ Clueless n00b. You can run asp, etc through the linux firewall.
\_ Dipshit, I know you can port forward, but he said
he wants a single fw/server. If that is the case

\_ Do a little research on reverse web proxies (specifically
URL based proxying)
\_ good thing all the politics threads got deleted,
so we can have intelligent technical dialog like

\_ I'd do linux if you already have it. It doesn't really need any
resources (P100 is fine) and if you don't play with it, will be
up for 3-6 months at a time (it's a cheap PC, so you'll probably
have some hardware failure or trip over the cord every so often.)
\_ or if you were lazy and had about $75, you could buy NAT-in-a-box
like a Linksys cable router/firewall, but then accessing your
linux box would be a bit trickier, if you needed to get at it
from the "outside".

They can do diagnistics on new modems that they can't do on

Oh, if you use @attbi.com for email, get ready to change

linksys for $50 (ROI <4months), and it works, except I lose
my csua connection whenever I leave for >10 minutes.
\_ They changed mine a long time ago. As far as buying vs. renting,
I rent because if you own your own and there's a problem the first
thing they do is tell you your equipment is the problem and hang
up on you. Also if it breaks or there's upgrades or whatever, they
replace it. I just want my net to work and I'm willing to pay a
few extra bucks a year for it.
\_ I bought mine because it was $10/mo. Then they actually reduce
it to $5/mo rental. Bastards.

my applications know which network to use? How does my browser
know how to go to Intranet sites via the wired (corporate) network?
The wireless network is a DSL connection only.
\_ I'm running both XP and RH8 on it. ipconfig in XP lists
the wireless connection first, then the local area connection,
but I don't think that's necessarily the order for the routing.
Is there a way to specify, say Opera to use the wireless
interface, and IE to use the wired ntework? (I haven't figured
out how to use the wireless in RH8 yet; 'ifconfig eth1 up' gets
it up, but I don't know how to get an IP ... it's a D-Link AP).

\_ I'm almost certain that there's no easy way to have
browser-based connection choosing, unless you write a
wrapper script around your browsers that
a) records existing network options
b) changes them for that browser
c) removes the changes on browser quit.
\_ You could probably do this with a local proxy. I haven't
played with anything under XP, but I believe squid can be
told what interface to listen on. If you gave it one of
your specific interfaces, I suppose it ought to work with
that one. Then just point your browser at it. As for the
IP, is the AP running in gateway or bridging mode? I
assume you also have to run dhclient or something similar
on the interface (assuming you're using DHCP.) Look at

any of their equipment--they're just doing research on usage
patterns. The first wave of access points were
Lucent (Orinoco), but we're starting to deploy Intel dual-band
(802.11a/b). The authentication box is by a company called
Vernier. -tom |

of e-commerce. http://www.youmaybenext.com

I want it today. 3C3FE574BT
\_ why a 574BT? thats a slower 16bit.. get the 575. i have bought
them from the dotcom depot at lawrence and arques near frys
in sunnyvale. -shac
\_ I think the CardBus drivers are expermiental/unstable in linux.
What OS do you use this card with?
\_ Fry's in Freemont?
\_ Thanks, I was wrong, Looks like the 3C3FE575CT is supported
Thanks, I hope it works. -op
\_ is this the place you're talking about?
http://www.diskdepot.com
\_ yes.. thats actually a separate store, next door,
owned by the same guy... both stores are GREAT. -shac
\_ Do you have a phone # or url for dotcom depot.
\_ try the same phone #.. too much junk
to list on a web page.
\_ Fry's in Fremont?
\_ nope, called em. |

11/6 What's the easiest way to resolve a name to an IP on a machine
that doesn't have bind. Is there a shell function?
\_ ping
\_ nslookup?
\_ many os's have "host", but ping is probably most universal.
\_ The machine doesn't have BIND installed? Or doesn't use a
nameserver? Check /etc/hosts (hostname.hme0 or whatever interface
on solaris.) Some Windows boxes have a file called lmhosts or
lmhosts.sam. There are web-based nslookups available for boxes
on the internet. If your machine doesn't use a DNS server, ping
won't return a remote machine's hostname, will it? Otherwise just
port scan it and see if it has any services running that might
return a host name (http, smtp) when you telnet to that port. -John
\_ Doesn't have BIND installed. It's a linux laptop. ping
does just what I originally needed, but I'm going to try
to install nslookup and dig (both of which are part of
the BIND distribution) without installing named.
-- I just copied the two files "dig" and "nslookup" from
the /usr/bin of a linux box I trust, and copied them
into the /usr/bin/ of my laptop. That was easy.
\_ vi /etc/hosts
\_ on solaris/BSD, you can just "arp hostname" to get IP.
Faster than ping.
Don't have linux near me to see if behaves the same way.
There are also web-sites that do nslookup for you as mentioned
above, but only if it's an Internet IP. |

11/5 hola, is there a "definite" book on photoshop [not superadvanced?]
kind of like stevens for tcp/ip ... something that stands head and
shoulders above the rest. ok tnx --psb
\_ If you're somewhat of a beginner, I've found that the
(many) books from Peachpit Press are very helpful and
easy to read. Check them out.

11/5 How do I find out who "owns" a specific IP address when it doesn't
resolve with nslookup? ie. There's a host down, and I want to
report the outage to the appropriate company.
\_ whois -a address (substitute -e or -p for non-US addresses) |

11/4 I'm about 9000 feet from the CO. In an apartment complex.
What kind of DSL speed can I expect? thanks.
The Covad phone answerer claims they already checked my apartment
and it can get 200/64.
What if I move to SF duplex at 7000 ft from CO?
\_ if thats what they claim at 7000' then the results of the MLT
must have been pretty bad... ask them what the results look like.
at 7000' you should be able to get their highest service unless
there is something wrong with your copper pair. if thats the case
then even DSL w/ pacbell will be limited.
\_ Why don't you ask Covad about your potential new address?
\_ http://www.dslreports.com/faq/4676
How about Telco ADSL?
\_ Covad routinely lies to get you to upgrade to more expensive DSL |
