netns-exec
|
||
|
|
==========
|
||
|
|
|
||
|
|
Runs command in Linux network namespace as a normal user. Does
|
||
|
|
essentially the same as `sudo ip netns exec <netns> sudo -u "$USER"
|
||
|
|
<command>`, but doesn't require sudo privileges or password.
|
||
|
|
|
||
|
|
This is a simple suid root program built around the code of `ip netns
|
||
|
|
exec` command of [iproute2] utility suite. The iproute2 source is
|
||
|
|
embedded in this git repository as a submodule.

Security note
|
||
|
|
-------------
|
||
|
|
|
||
|
|
This program is installed as suid root. Normally, only root can
|
||
|
|
execute anything in a different network namespace. This program
|
||
|
|
intentionally bypasses this restriction and should not be installed in
|
||
|
|
a machine where this is a problem.
