I tried a vnamespace -e service ip addr add 172.29.50.163/24 brd 172.29.50.255 dev eth1 to add an interface to the guest called service But this is probably the wrong command :-( I get an additional ip that is shown on the root-vserver 3: eth1: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000 link/ether 00:0e:0c:71:0f:8e brd ff:ff:ff:ff:ff:ff inet 172.29.50.100/24 brd 172.29.50.255 scope global eth1 inet 172.29.50.199/24 brd 172.29.50.255 scope global secondary eth1 ... inet 172.29.50.163/24 brd 172.29.50.255 scope global secondary eth1 But no new interface is shown inside the guest: [EMAIL PROTECTED]:/etc/snappy# vserver service enter service:/# ip addr show 3: eth1: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000 link/ether 00:0e:0c:71:0f:8e brd ff:ff:ff:ff:ff:ff inet 172.29.50.199/24 brd 172.29.50.255 scope global secondary eth1 I'm running: Kernel: 2.6.16.25-vs2.0.2-rc20-grsec2.1.9 VS-API: 0x00020001 util-vserver: 0.30.210; Mar 3 2006, 14:06:42 TIA, Oliver _______________________________________________ Vserver mailing list Vserver@list.linux-vserver.org http://list.linux-vserver.org/mailman/listinfo/vserver
