Hi guys... I have something that keeps diving me nuts and I still can not find an answer... I have a FreeBSD R30.0 inside a network protected by a firewall. Such firewall is configured to expire TCP sessions after 15 min. of inactivity. When I login to the FreeBSD box, I frequently forget the session and -obviously- the firewall expires (terminate) my session. Neither my Win95 telnet program or the telnetd realize this really soon enough so I have to manually kill the telnetd session. I need to know how to tweak this parameters. As I understand it, I have three options: 1.- Tweak the firewall's TCP timeout. 2.- Tweak FreeBSD's tcp.keepalives. 3.- Tweak telnetd's keepalives. I do not want to go for options 1 & 2 since it would affect not only my session but all my traffic. So I figured that the right thing to do is to tweak telnetd's keepalive. Now, does anybody know what the "1" means in this line?, taken from /usr/src/libexec/telnetd/telnetd.c int keepalive = 1; I also figured this would be the line to mess with, right? Could anyone, please please please shed some light here? Could you please answer (if any) to denp@acnet.net Best Regards... Ivan Villalobos Ashton Communications Corp. NOC McAllen, TX.
