How to piss away your brand-name

With v5 of its great WRT54G wireless router, Linksys went from a Linux-based OS to a VxWorks-based OS. Why? Hardware. Even a free Linux has its costs: it required them to use twice as much RAM. The Linux based product is one they've been debugging for many years; there are probably millions out there. The VxWorks one is brand new, and going through all the obvious quality pains you would expect. One classic issue that has returned is the timeout of inactive connections. Tech support was ever oh-so-useful. Check out how it's supposedly confidential, too. Bleah.

If I leave a telnet or ssh session open for ten minutes with my WRT54G, the connection is forcibly closed. This wasn\'t a problem with my previous WRT54G. I am running "Firmware Version: \tv1.00.4, Dec. 8, 2005" How can I change or eliminate this value?

Egads.

Did you ever get that fixed? I just bought one of these and I'm going to return it tomorrow. Just ridiculous that these routers cut off idle connections.

Nope, I didn't. I set up my Linux boxes to send a keepalive of 90 seconds by setting the value in /proc/sys/net/ipv4/tcp_keepalive_time and that keeps most of what I'm concerned about working well enough.
