My colleague over at PBSPlaza wrote a nice article about enabling squid on eSafe Gateway 7.1 Forwarding Proxy. Today I had to configure an extra step to enable squid. I followed the instructions from my colleague, but when I tried to start squid I received the following error message.
FATAL: Could not determine fully qualified hostname. Please set ‘visible_hostname’
Squid Cache (Version 2.6.STABLE18): Terminated abnormally.
CPU Usage: 0.030 seconds = 0.000 user + 0.030 sys
Maximum Resident Size: 0 KB
Page faults with physical i/o: 244
Aborted
I added the following line to /opt/eproxy/etc/squid.conf:
visible_hostname mail.booches.nl
Now squid starts perfectly
