Hello, Sometimes my dom0 network is stalled. When it happens, the arp cache on the other machine has FE:FF:FF:FF:FF:FF. me@mymachine:~# arp Address HWtype HWaddress Flags Mask Iface <snip> xen1test.my.domain ether FE:FF:FF:FF:FF:FF C eth0 <snip> This means xen1test replies to arp with wrong mac address? It recovers automatically when arp cache expires or doing something like ping from the problematic dom0 and the other machine happens to pick up the right mac address. me@mymachine:~# arp Address HWtype HWaddress Flags Mask Iface <snip> xen1test.my.domain ether 00:19:DB:6A:1E:29 C eth0 <snip> Xen and kernel are from Ubuntu Gutsy (3.1.0). Is this Ubuntu specific problem? Does anybody know how to fix/workaround this? TIA, Takeshi _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
