Hallo, Tom, Du meintest am 09.06.11: > I need to verify, if I get a mail when squid dies (I put a correct > mailaddress in cache_mgr-directive). Is there a way/hack to force > squid to die? Yes - this daemon is started from a script p.e. with the command /etc/init.d/squid start (the command depends on your distribution). And stopping squid is nearly the same command. Brute force (under a linux distribution): killall squid (if you are curious: repeat the command) Viele Gruesse! Helmut
