hi,
Remove the /etc/sysconfig/network-scripts/ifcfg-dummy0 file and restart the network service and check.
Reagrds,
Sark.

Hi,
When working with LVS I need to add dummy0 interfaces to the real
servers like this:
#ifconfig dummy0 192.168.10.7 netmask 255.255.255.0
This then shows up and works nicely:
[root@gbcdff1274m ~]# ifconfig -a
dummy0 Link encap:Ethernet HWaddr DA:37:9F:77:D0:99
inet addr:192.168.10.7 Bcast:192.168.10.255
Mask:255.255.255.0
inet6 addr: fe80::d837:9fff:fe77:d099/64 Scope:Link
UP BROADCAST RUNNING NOARP MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:3 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:0 (0.0 b) TX bytes:210 (210.0 b)
The problem is, the servers are shared and after testing I need to hand
them back, the only way I know to remove the dummy0 interface is to
reboot the machine, is there a nice way I can remove it from the command
line without a reboot?
I've tried:
ifconfig dummy0 down, this disables it but it remains in the list.
/etc/init.d/network restart and it still remains
Any help much appreciated.
