Hi, ps -Z => squid_t and getenforce => enforcing squid is started with selinux Redhat/centos platform: If squid is installed with yum, squid will be started with a squid_t selinux context. If you compile your squid and installed it, you will have to change squid files contexts manually. As i see you have squid_kerb_plugin, you should have compile you squid to support kerberos, no? --- For your problem: try to check selinux log: audit2allow -al or cat /var/log/audit/audit.log | audit2allow You can also try to restore selinux context for all squid files: restorecon -R /etc/squid restorecon -R /var/log/squid etc... or touch /.autorelabel and reboot Tiery On Tue, May 18, 2010 at 9:47 AM, GIGO . <gigoz@xxxxxxx> wrote: > > Dear All, > > Your guidance is required.
