Re: Telnet Operation Timed Out
Yes it was a good question, and my connections timeout faster than before. I don't think you can do something like that with ipfw. But I might be wrong, Perhaps, you can find a telnet client that suits your needs. BTW I think an overall TCP connection timeout set to 10 seconds is a good idea. But then again you might have problems with overloaded sites. That would be very rare, though. Cheers, NikV On Wednesday 14 April 2004 20:55, Holtor wrote: > Nikos, > > Thank you so much!

Re: Telnet Operation Timed Out
Nikos, Thank you so much! The value is not in seconds but in milliseconds (wierd?). I set it to 1 ms which gave me a 10 second timeout however this is system-wide and I dont want to break things. Does anyone know how to do it for just this specific telnet session? Perhaps there's a keepinit rule in ipfw. Any ideas?

Re: Telnet Operation Timed Out
The timeout seems to be 75 sec, how can we make this 15 or 30 seconds? I have been searching google to no avail but did get hints that this might be a TCP default of somekind. IMHO it's TCP, nothing to do with "telnet" itself, Perhaps you can use a sysctl command to extend the tcp timeout value. (I just looked but i could not find one that should do the job.) but that might also tell one that tcp values are default, a timeout always occurs in x seconds (where x is staticly defined). HTH, If anyone has any idea please do e-mail back but include my in the reply as I'm not yet subscribed to the list.

Re: Telnet Operation Timed Out
You can change the non-established-connection-timeout using sysctl net.inet.tcp.keepinit=value. The default is 75000, at least on FreeBSD-4.9, which is probably a lot.
