Daemon not running when started over ssh

Daemon not running when started over ssh

I am trying to start the rngd daemon by remotely starting it via ssh.
Unfortunaltely it does not seem to run until I log onto the machine. The
command I am using is:
ssh -n -o StrictHostKeyChecking=no -i ... user@host "sudo rngd -r
/dev/urandom -o /dev/random -t 10"
When I call cat /proc/sys/kernel/random/entropy_avail I get low (150ish)
values which makes me think that rngd is not running. However if I log
onto the box, wait a few seconds and check, the pool is full (3000s).
