I have this problem on several Sun on our LAN.
When our LAN manager replaces the firewall box that divides
2 parts of the same LAN or the dns box
(same ip-address but different mac-address)
my SUNs can not reach the other part of the network, while other
linux box could reach one to each other on the same 2 branches of the
It seems that those computer do not recognize that
the couple ip-address mac-address has change.
When I reboot, than everything work fine again.
Unfortunately I missed the chance to delete the ARP entry
from the table and see what happen.
Do you have any suggestion for fixing the problem?
Thanks in advance
