Re: Ultra 5 SSH/Ethernet Lockup
It looks to me like you are ssh'ing from behind a firewall (using ipv4)
that has a very short timeout for tcp connections. does this happen
between local machines as well???
If this is the case than it is not related to which ethernet card you use
or which protocol... but just to the firewall setup.
