Re: [Wlug] Looking for dial-up provider (Westboro area)

by Gary J. Hanley

Until late last year I would have recommended my ISP, www.theworld.com. However they have faltered as of late, especially with their mail system and other small issues that add up to one big one. But, you can get a cheap and limited account there so if he doesn't mind dealing with intermittent email issues maybe it's what he's looking for...? -- Gary On Wed, 3 Apr 2002, Stephen C.

Looking for dial-up provider (Westboro area)

by Stephen C. Daukas

A friend of mine has a small business in Westborough and I helped put together a web site for him. He now wants to dump AOL and get a less expensive "dial-up account". Anyone have a recommendation? He is paying ~$25/month for AOL... He doesn't want/need Charter, just wants to check mail a few times during the day. Also, anyone know if you can set-up email forwarding in AOL? Thanks! Steve

Re: [Wlug] Problems dropping telnet sessions

by Jason Calvert

Sounds like a firewall problem. Just for fun you might try lowering your keepalive time to say 29 min, or even lower just for testing, and see if that helps. The default is 2 hours (7200 sec) or 14400 half sec on bsd) cat /proc/sys/net/ipv4/tcp_keepalive_time 7200 you can use sysctl or just echo the new value in echo 1740 > /proc/sys/net/ipv4/tcp_keepalive_time or sudo /sbin/sysctl -w net.ipv4.tcp_keepalive_time=1740 Anyone know if this works for clients as well as daemons?

Try ipchains -L too, since you might have an ipchains based firewall.

Maybe the TCP timers are different on Linux? They are in /proc/sys/net/ipv4/tcp*. Some docs for these variables are available here: http://www.linuxhq.com/kernel/v2.4/doc/networking/ip-sysctl.txt.html You might also want to look at the tcp(7) manual page where they also document the sysctls: man 7 tcp -- Charles R.

RE: [Wlug] Problems dropping telnet sessions

I executed the iptables -L command and got the following output: Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination I'm not really that familiar with firewalls in linux, but I would assume that iptables is running without rules? I also noticed that it's not one particular host that bumps me out of telnet, but all connections and all hosts. The network folks don't know (or maybe they do) that I'm running linux on the network, but is there a way for them to periodically reset the port I'm using in the data closet? This is really quite interesting to me, so any input is very helpful.

My first two thoughts are: iptables times out your connection for some reason, or the remote side has an autologout value set. Is there a firewall setup on your box? You can do "iptables -L" to find out. As for autologout, I would think this would have affected you before, but it's something to rule out anyway. What shell are you using on the remote machines? If it's a csh variant, run "echo $autologout" and see what it comes back with. If it comes back with a defined non-0 value, that is a likely cause of your problem. Run "set autologout=0" and see if that fixes your problem. -- Randomly Generated Tagline: "Note that if I can get you to \"su and say\" something just by asking, you have a very serious security problem on your system and you should look into it."
