127.0.1.1 ubuntu
# The following lines are desirable for IPv6 capable hosts
::1 localhost ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
i check my hostname file , i see this text:
server1.yourdomain.com

after change i run again this command:
sudo service squid restart
and this command
sudo service squid stop

sudo service squid reload
sudo: unable to resolve host server1.yourdomain.com: Resource temporarily unavailable
squid.service is not active, cannot reload.
i check ping ip , get good ping
how to fix this problem?
