firewall. sshd forks a new process to recieve the connection but this then waits
forever for more data.
If I "service iptables stop" within the guest then all works OK.
I believe this is fixed by

This only fails if ssh'ing from another (any) domU to the 2.6.9-67.EL xenU/domU
on the same local machine.
ssh-ing from dom0 works; ssh-ing from another remote machine works also.
I think you mentioned that this ended up being just a bug in the RHEL-4 PV
kernel, and not in the RHEL-5 PV kernel. Assuming that is the case, can you
close this bug out?
Correct, it's only in rhel4-xenU.
thought I closed this bz.... will do so now...
