Hi, Thanks for your help so far. ATM: pstree: |-squid---squid---unlinkd ps aus | grep squid: root 20538 0.0 1.3 3344 416 ? S Oct31 0:00 squid #23 20539 0.0 7.9 6004 2440 ? S Oct31 0:02 (squid) yet ./squid -k check gives: squid: ERROR: No running copy The dnsserver doesn't appear (it should be) and unlinkd doesn't appear under a grep. I'm baffled. -André
