Hi,

I'm sorry if somehow you took away that I didn't do anything for
the 2 minutes. Every time I'm testing I am either scurring to get something
typed in before it disconnects, or I am running "ls" over and over and having
it quit mid my typing or mid the response.

Absolutely not a timeout issue. When I was asked to do the last
test, it took me 7 logins just to get screen running, start tcpdump
writing to a file listening on 2022, and in another window start ssh on
2022. So there was never a second I wasn't typing or there wasn't screen
interaction, and it still dumped me 6 times.

The only reason I was able to get that long seemed to be using
the ProxyCommand. Without it, normal sessions lasted anywhere from 0
(Yes, it would disconnect before I could type the 8 character password
I've been using for 29 year and could type in my sleep) to 15 or 20
seconds.

I also get knocked off of SSH from the ROUTER ITSELF.

So this can't be it.

I set up where past the "router" and laptop, I wireless connected
to a home router, and then out to the net. With this, if I ssh to a
machine outside the site, I can stay connected for DAYS.

laptop->router+ddwrt|====air===|router+ddwrt->laptop+NAT===air===router->cablemodem
.....................SSH PROBLEMS HERE.SSH PROBLEMS H...............................

I'm guessing if RSTs are generated, they aren't able to get to/past
the cable modem.


Thanks, Tuc
