Summary:
My squid-2.5.STABLE9-8 running on FC4 (kernel 2.6.12-1.1447) and have
no problem until I introduce ncsa authentication, following the
instruction found at
http://www.linuxhomenetworking.com/linux-adv/squid.htm
Error message "WARNING: Cannot run '/usr/lib/squid/ncsa_auth' process"
found in cache.log when squid starts with /etc/rc.d/init.d/squid
script. Client browsers still see authentication screen, but squid
crashes and restarts after the client provides userid / password and
hit Enter key. In addition, many pids are assigned to squid. After
crashing and restart, some more pids are added to this list.
Squid starts and authenticates normally if we start squid from command
line instead, i.e. type #squid. No error message found in cache.log,
and client can access internet if proper id and password provided.
Details:
- Start squid using /etc/rc.d/init.d/squid script and see this warning
in the cache.log
-|- /var/log/squid/cache.log
