-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Dunno if this is relevant--but I had similar symptoms SSH-ing to an OpenBSD SSH server through IPTables on RH running through an OpenVPN tunnel (RH/IPTables was the OVPN server)... I didn't really spend the proper time troubleshooting what was actually causing it--so this may not apply to your situation at all... (enough disclaimers yet?) What fixed it for me was setting the following in sshd_config of the SSH server: ClientAliveInterval 10 ClientAliveCountMax 6 Again--no idea if this is of any value to anyone... - -j -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.3 (GNU/Linux) iD8DBQFA9HBFqca8HlBdgZoRArZeAJ9rkciHNTmhDythmAkF9efUf2GC/ACeKys6 z3b6eXHHIcuFfkVQ50XI7ng= =+8ya -----END PGP SIGNATURE----- -----Original Message----- From: Real Cucumber [mailto:monkcucumber@xxxxxxxxx] Sent: Tuesday, July 13, 2004 12:51 PM To: netfilter@xxxxxxxxxxxxxxxxxxx Subject: SSH Connections Lost After 1 minute idle I have a fedora firewall/router using iptables to forward incoming SSH packets to an internal server and it works great....however, only if the user does not remain idle for 1 minute. If they idle for 1 minute, the connection "freezes" in the sense that it drops the connection but its not a proper "connectoin closed" from the server as if it is a timelimit, but rather just a connectoin loss like you've unplugged your cable in the middle of a connection. If the user is connecting from within the network, they can remain idle for an unlimited amount of time without being disconnected. It is only ones connecting from outside hte network going through the iptables firewall that have this idle problem. I am only allowing TCP and UDP for SSH to be forwarded. Do I need any ICMP or any other special connection timeout rules on the iptables side to fix this problem? Any help appreciated! __________________________________ Do you Yahoo!?
