As nobody is accessing Internet I just simply executed squid -k reconfigure and I got: root@fenix:~# squid -k reconfigure squid: ERROR: Could not send signal 1 to process 1033: (1) Operation not permitted Hello Jaime, Check your cache_effective_user directive in squid.conf and check which user id your Squid process is running under. If you start Squid as root, it will change its effective/real UID/GID to the user specified below. The default is to change to UID to nobody. If you define cache_effective_user, but not cache_effective_group, Squid sets the GID to the effective user's default group ID (taken from the password file) and supplementary group list from the from groups membership of cache_effective_user.
