Henrik,

My start script reads as below

#!/bin/sh
exec 2>&1
exec squid -f /etc/squid/squid.conf -N

I set the following line in /etc/squid/squid.conf

cache_access_log /dev/stdout

I set the write bit for other in the /dev/ directory. The permissions
on /dev read

drwxr-xrwx 9 root root 4620 Sep 20 14:57 dev

I also set the write bit for other for /dev/stdout. On CentOS 4.1,
/dev/stdout is a symlink for /proc/self/fd/1 which is in turn a symlink
for /dev/pts/0. The permissions on /dev/pts/0 are as follows

crw--w-w- 1 marlowe tty 136, 0 Sep 20 16:51 /dev/pts/0

It is my understand that with these other write permissions in place,
the user squid should be able to write to /dev/stdout. However when I
attempt to start squid, I still receive the same error message. I tried
to run my start script from the CLI and received the same error
messages. What else should I be looking at?

Thanks,
Patrick
