Is it possible to use sudo with !requiretty for a specific command

sudo

I am trying to allow a specific command to be run under sudo without a tty. I found that I can disable requiretty for a group :

Defaults:%support !requiretty

But I dont know how to do it for a single command. Is it possible at all ?

You should be able to do:

Cmnd_Alias                NOTTYCMDS = /path/to/cmd1, /path/to/cmd2
Defaults!NOTTYCMDS        !requiretty

you can specify "" to indicate that the command may only be run without command line arguments.

So in your case, you'd probably do something like:

ALL ALL=(root) /sbin/mii-tool ""

(Probably throwing in a NOPASSWD: for convenience)

You need to have key deployed for root, not for your user. When you do sudo the command executed under root user and not your.

Also you perhaps should reconsider how you do it. IMO this is not correct way to pull as sudo.
