Once again I am seeing a tcp oddity. This might be unfixable, but I
thought I would bring it up in case it's exposing a linux tcp bug.
The situation:
My friend gets on the net through a ppp connection to an ISP. He sets
his mtu to 552 to get better interactive proformance.
His ISP stupidly deny's all icmp to their modem pool. :(
If he logs into my machine running 2.1.94, he can login fine, but the
first thing he does that sends out more than a line or two of output
locks up his session. Total freeze.
I tried enabling ip_no_pmtu_disc in an attempt to work around their
broken setting, but the same thing happens. ;(
I know the provider is broken. I know my friend should switch or get
them to change things, but it would be nice to have a work around for
such broken situations. ;)
Shouldn't pmtu_discovery fix this situation? What else are icmp's
needed for in a normal tcp session?
Here is a tcpdump of both login attempts...
