RE: [PHP] Test if a daemon is running...

I would like to monitor 3 different daemon : postfix, amavisd (a virus scanner acting as a content filter for postfix) and spamd (SpamAssassin, a spam filtering daemon invoked by procmail acting as an SMTP server). Can we be sure that a daemon is running if the .pid file exist?

What type of daemon? eg: To see if my pop3 daemon is running I use sockstat... "sockstat | grep 110" and process the output. eg: To see if my mail redirect daemon is running I check /var/run/red_mail.pid All depends on what you want to do as to how you do it. You could even do it in a multitude of ways and use the resulting matrix to determine. -- Dan Hardiker [dhardiker@staff.firstcreative.net] ADAM Software & Systems Engineer First Creative Ltd > Hello everybody, > > I would like to know an easy way to check is a daemon is running. > > What do you think is the best?
