The Feb 26th InstallFest held at Dartmouth College (NNHLUG)
Here are the Pictures from this event: http://www.nnh.net/nnhlug/feb26meeting.html We had about 35 people at this event. Dartmouth bought pizza and sodas for the event, and provided a very plush room for us. There was a 100Mb LAN installed for us. It was very informal, and the whole event basically ran itself. People basically all pitched in and helped eachother. It was really very cool to be a part of. Just wanted folks to know that NNHLUG is still plugging away ;-) Tim R. Havens NNHLUG - www.nnh.net
Meeting
Ok... IIRC there's a meeting tomorrow night in Manchester, no? Would someone be kind enough to repost the location and directions? I had the original message in my inbox at my former employer, which now no longer exists... :-) Unless... Paul, did you rip a CD of my home directory?? -- PGP/GPG Public key at http://cerberus.ne.mediaone.net/~derek/pubkey.txt -- Derek D.

Re: Feb 29th Meeting
The Feb 29th meeting is at Stark Mill Brewery, 500 Commercial Street, Manchester. 7 PM, 3rd floor - Riverview Room. Taos, Inc will have pitchers of beer and appetizers upstairs in the meeting room at approximately 6:45. A grooup of us are having dinner at approximately 6-6:15 pm. Directions: North on 93 past the 101 offramp. Continue to Exit 5 ( I think it is Granite Street). After you get off of the offramp, get in the left hand lane and turn left on Commercial Street (it is either 1st or second stoplight). Go about 3/10 of a mile and you should see the Stark Mill Brewery sign on a three story buildign on left side of street. Anyone who is planning on dinner before, let me know so I can make sure we have enough tables. Jerry Ok... IIRC there's a meeting tomorrow night in Manchester, no?

talkd[12550]: recv: Socket operation on non-socket
Hi everybody,
I set up rules for a masq firewall, but the talk stopped working afterwards
with the ${SUBJECT} nice little message.
I figured out that the problem was that I started out this way:
ipchains -P input DENY
ipchains -P forward DENY
ipchains -P output DENY
If I have both input and output denied, talk doesn't work on localhost anymore.
Alright, I tried to accept everything from the localhost:
ipchains -A input -s 127.0.0.0/8 -d 0/0 -i lo -j ACCEPT
ipchains -A output -s 127.0.0.0/8 -d 0/0 -i lo -j ACCEPT
(And a few more tryings similar to this, with no luck)
But this is not enough. What else is needed so that everything gets denied from
eth0 and eth1, and nothing from lo? I hate talkd:-(.
Thanks, Ferenc

Samba Question
Hi All, Questions: 1. Is it possible to mount DAT tape from windows PC connect to linux server running samba? 2. How LAN speed suffers if Linux BOX is used as a file and database server for 5 users. (Linux Box running Oracle 8.0.4 and Samba, Windows PC running Developer 2000 forms and report). I want to keep the program in a shared directory (/home/prg). 3. How can I use this box as a Fax server? Thanks in Advance for your valuable time. Best Regards, Nadeem Kafi. Random Quote: "Business is war, and the Internet is tank warfare.

Re: talkd[12550]: recv: Socket operation on non-socket
Ferenc Tamas Gyurcsan did expound, once apon a Today:
Hi everybody,
I set up rules for a masq firewall, but the talk stopped working afterwards
with the ${SUBJECT} nice little message.
I don't know what "with the ${SUBJECT} nice little message" means, but I
think I can help you.
I figured out that the problem was that I started out this way:
ipchains -P input DENY
ipchains -P forward DENY
ipchains -P output DENY
Ain't IPCHAINS fun? :)
If I have both input and output denied, talk doesn't work on localhost
anymore. Alright, I tried to accept everything from the localhost:
ipchains -A input -s 127.0.0.0/8 -d 0/0 -i lo -j ACCEPT
ipchains -A output -s 127.0.0.0/8 -d 0/0 -i lo -j ACCEPT
From whay you've said it seems to me that you want talk to work for anyone
on the local machine, but not from another machine on your local network,
and not from your external network.
There are a few things you need to realize:
1) Talk is a UDP service.
1) your machine has 3 IP addresses. On the local machine, a packet could
concievably originate from any of them, and still have originated on
the local machine. I don't understand how the kernel decides what IP a
packet originates from, but my experience tells me it ISN'T what you
would think it would logically be. But then again, I may be on crack.
2) You need to allow talk both FROM the local machine, and TO the local
machine.
3) The source port for a talk connection will be a randomly assigned,
non-priveledged port.
That last one is the part that makes this very tricky. You almost have to
allow everything in to let stuff like this work. Explaining this would be
much easier if I knew what IP addresses you had assigned. I'm just going
to assume your IP addresses are 192.168.1.1 for your internal card, and
24.1.1.1 for your external connection. I'll also assume that your eth0 is
for internal network and eth1 is for external connection (this is
preferable IMO). You will need to do something like this:
# accept talk traffic FROM local machine
ipchains -A input -s 127.0.0.0/8 -d 0/0 517 -p UDP -j ACCEPT
# accept talk TO local machine, if it originates from a local IP
ipchains -A input -s 192.168.1.1 -d 127.0.0.1 517 -p UDP -j ACCEPT
ipchains -A input -s 24.1.1.1 -d 127.0.0.1 517 -p UDP -j ACCEPT
Note that if you do it this way, you MAY need to do something like this
for EVERY chain (input, forward, and output), and you *WILL* need to do it
for EVERY service you want to allow, if all of your default policies are
DENY.
Also note that in and of itself, this does not prevent IP spoofing, but
the kernel has an option that makes sure that IP packets originate from
the interface that match their IP address. I don't remember which one it
is off the top of my head (OTTOMH) but I think it's one of the ones that
makes firewalling work, so you probably already have it turned on.
Make sure you are not running version 2.2.11 -- it has a memory leak that
will eventually crash your system. It might have been 2.2.12 -- I can't
remember. Just make sure you're up to date and you don't need to worry
about it.
I highly recommend that you read and re-read the IPCHAINS Howto.
