Hi list, on a customers' site I have a problem connecting from within their LAN (OpenBSD machine) crossing their router (Linksys BEFSX41, doing NAT) to a machine on the internet via SSH: Sessions die after some time due to 'timeouts'.
If the connection is not used heavily (e.g. showing top(1)) it dies (the router clearing it's session cache); it's a well-known issue with this kind of customer-class devices (lots of entries on your favorite search engine). A solution (for GNU/Linux) would be to increase /proc/sys/net/ipv4/tcp_keepalive_time as I got from a newsgroup; however, on OpenBSD I just see net.inet.tcp.keepinittime net.inet.tcp.keepidle net.inet.tcp.keepintvl I tried to increase (and decrease, just to determine if there's any difference) net.inet.tcp.keepidle, but it didn't make a difference. Think I'm using the wrong knob -- is there something similar on OpenBSD (like tcp_keepalive_time) to cheat on the NAT thing? (And, yes, using a WRAP board running OpenBSD as router works perfectly well in the same environment; however, the Linksys has to stay there...) TIA, Timo
