Dear all, I use squid on my personal computer to provide HTTP proxy service to myfriends at college. I'm not a sysadmin --- just using squid occasionallywhen necessary. I use a basic authenticator module written in Perl byThomas Börnert "squidauth.pl" <http://www.tbits.org/html/squidauth.html>. The problem was like this. I recently upgraded my squid version from 2.6to 3.0 after an OS upgrade. Back in the 2.6 days the module worked fine.After I ported the authentication part of my squid.conf to the 3.0version, it stopped working. After the squid service was started, theauthenticator processes got terminated unexpectedly. I looked at my logsand found the suspicious lines (from /var/log/squid/cache.log): [ omitted: squid initializing ]2008/05/18 03:21:49| helperOpenServers: Starting 5 'squidauth.pl' processes2008/05/18 03:21:49| ipcCreate: /usr/lib/squid/squidauth.pl: (13)Permission denied2008/05/18 03:21:49| ipcCreate: /usr/lib/squid/squidauth.pl: (13)Permission denied2008/05/18 03:21:49| ipcCreate: /usr/lib/squid/squidauth.pl: (13)Permission denied2008/05/18 03:21:49| ipcCreate: /usr/lib/squid/squidauth.pl: (13)Permission denied2008/05/18 03:21:49| ipcCreate: /usr/lib/squid/squidauth.pl: (13)Permission denied[ ... stuff omitted ...]2008/05/18 03:21:49| Accepting HTTP connections at 0.0.0.0, port 3128,FD 19.2008/05/18 03:21:49| Accepting ICP messages at 0.0.0.0, port 3130, FD 20.2008/05/18 03:21:49| HTCP Disabled.2008/05/18 03:21:49| Ready to serve requests.2008/05/18 03:21:49| WARNING: basicauthenticator #1 (FD 8) exited2008/05/18 03:21:49| WARNING: basicauthenticator #2 (FD 9) exited2008/05/18 03:21:49| WARNING: basicauthenticator #3 (FD 10) exited2008/05/18 03:21:49| WARNING: basicauthenticator #4 (FD 11) exited2008/05/18 03:21:49| Too few basicauthenticator processes are runningFATAL: The basicauthenticator helpers are crashing too rapidly, need help!
