Hi all, A client just phoned me and said he could not SSH into his VPS, yet he can ping it. So, I login to the host node, and check it out, can''t SSH into. I shutdown iptables on the VPS (via xm console serverza.vm) but still can''t SSH into it. I restart the VPS, still can''t SSH into it. So, I check the host, and found this in /var/log/messages: Jul 22 19:19:07 zaxen01 kernel: xenbr0: port 6(vifserv0) entering disabled state Jul 22 19:19:07 zaxen01 kernel: device vifserv0 left promiscuous mode Jul 22 19:19:07 zaxen01 kernel: xenbr0: port 6(vifserv0) entering disabled state Jul 22 19:19:46 zaxen01 kernel: device vifserv0 entered promiscuous mode Jul 22 19:19:46 zaxen01 kernel: ADDRCONF(NETDEV_UP): vifserv0: link is not ready Jul 22 19:19:46 zaxen01 logger: /etc/xen/scripts/vif-bridge: iptables -A FORWARD -m physdev --physdev-in vifserv0 -s 196.34.x.x 196.34.x.x -j ACCEPT failed.

The other 3 VPS''s on the same node works fine though -- Kind Regards Rudi Ahlers CEO, SoftDux Hosting Web: http://www.SoftDux.com Office: 087 805 9573 Cell: 082 554 7532 _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I restart the VPS, still can''t SSH into it.Maybe someone with the same MAC has started it''s VPS and this VPS is not running an SSHd? Start tcpdump on your VPS and check if packets arrive.
