Emulab FAQ: Testbed Operations: How do I control verbose syslogging in tmcd?
There is a signal handler to change the verbosity of a running tmcd. To turn on verbosity:
kill -USR1 `cat /var/run/tmcd.pid`
To turn off verbosity:
kill -USR2 `cat /var/run/tmcd.pid`
You can send the signal to individual children, but that would be silly and pointless.
