Hi,
We are running Xen 3 on Debian and have 4 guests running. www, sql, ns1
and mail.
I am wanting to shut down mail and let the host take over the task.
I have setup postfix, imap etc on the host ready to take over.
I halted mail and added an interface alias to the host with the ip and
netmask of mail.
But I am unable to ping/ssh to the interface alias out side of the host
or other other guests.
This is the /etc/network/interfaces of the host
auto eth0
iface eth0 inet static
address 192.168.1.180
netmask 255.255.255.240
gateway 192.168.1.179
auto eth0:1
iface eth0:1 inet static
address 192.168.1.181
netmask 255.255.255.0
We can use from 180 to 190 in the address range. If I setup the alias
with 188 I can ping and ssh without issue.
So even though the mail guess is shutdown in traffic still routed to it
some how?
Any help would be appreciated.

Nothing Xen specific, really. Try to force-update neighbour/router''s arp cache, using command (from your host): arping -b -I eth0 -s 192.168.1.181 192.168.1.1 where the last ip address is the ip address of your router. -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
