Hi frank

Tried it and got this: -

Code:
/home/brad > cat runAgent.err
sudo: no tty present and no askpass program specified

make the sudo rule less complex.


put "/usr/bin/nohup /home/brad/spideroak/jsystem/runner/runAgent > /home/brad/runAgent.out 2> /home/brad/runAgent.err < /dev/null &"

into a script
and make the sudo rule look like this
Code:
brad ALL = (root) NOPASSWD: /usr/local/bin/foo.ksh



also for security reasons I suggest putting the binaries into a root owned location and also would not write root output to your home directory.

It will prompt for the password and then execute the command asynchronously (i.e. in the background if you think that way) and, in the wee bit of testing I did here, it seems to ignore hangup signals, so you can exit without taking the process down.
Hi

Well I tried -b and -n but both still killed the job when I exited: -

Code:
/home/brad/spideroak/jsystem/runner > sudo -n /usr/bin/nohup /home/brad/spideroak/jsystem/runner/runAgent </dev/null >~/runAgent.out 2>~/runAgent.err &
[1]     2425
/home/brad/spideroak/jsystem/runner > (PRESSED ENTER KEY HERE)
[1] +  Done(1)                 sudo -n /usr/bin/nohup /home/brad/spideroak/jsystem/runner/runAgent </dev/null >~/runAgent.out 2>~/runAgent.err &
/home/brad/spideroak/jsystem/runner > (CONTROL D HERE)
/home/brad/spideroak/jsystem/runner > You have stopped jobs
/home/brad/spideroak/jsystem/runner > exit

I set the sudo entry as: -

Code:
brad ALL = (root) NOPASSWD: /usr/bin/nohup /home/brad/spideroak/jsystem/runner/runAgent </dev/null >~/runAgent.out 2>~/runAgent.err &

Thanks Frank

That did the job.

Will tidy it up tomorrow and implement your security suggestions.
