Correct way of bringing network interface down in linux
- by Karolis T.
For example:
$ ifconfig dummy0 up
$ ifconfig dummy0 "192.168.1.190 netmask 255.255.255.0"
Calling ifconfig with no parameters shows the interface
dummy0 Link encap:Ethernet HWaddr b6:1f:f3:92:6d:20
inet addr:192.168.1.190 Bcast:192.168.1.255 Mask:255.255.255.0
inet6 addr: fe80::b41f:f3ff:fe92:6d20/64 Scope:Link
UP BROADCAST RUNNING NOARP MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:15 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:0 (0.0 B) TX bytes:1050 (1.0 KiB)
How can I bring the interface down so that it doesn't show up in
ifconfig
ifconfig -a
ifconfig dummy0
without
rmmod dummy
because dummy is used just for example purposes.
If there is no way to do that, what "throw-away" IP could I set to it and be safe from any trouble?
like
$ ifconfig dummy0 down
$ ifconfig dummy0 0.0.0.0
