so, consider that Squid is made completely accessible to anyone by this action. Therefore,
define ACLs that control access to the proxy. More information about this is available
in Section 41.4.2, "Options for Access Controls" (page 794).
After modifying the configuration file /etc/squid/squid.conf, Squid must
reload the configuration file. Do this with rcsquid reload. Alternatively, completely
restart Squid with rcsquid restart.
The command rcsquid status can be used to check if the proxy is running. The
command rcsquid stop causes Squid to shut down. This can take a while, because
Squid waits up to half a minute (shutdown_lifetime option in /etc/squid/
squid.conf) before dropping the connections to the clients and writing its data to
the disk.
WARNING: Terminating Squid
Terminating Squid with kill or killall can damage the cache. To be able
to restart Squid, the damaged cache must be deleted.
If Squid dies after a short period of time even though it was started successfully, check
whether there is a faulty name server entry or whether the /etc/resolv.conf file
is missing. Squid logs the cause of a start-up failure in the file /var/log/squid/
cache.log. If Squid should be loaded automatically when the system boots, use the
YaST runlevel editor to activate Squid for the desired runlevels. See Section 8.5.12,
"System Services (Runlevel)" (page 162).
An uninstall of Squid does not remove the cache hierarchy or the log files. To remove
these, delete the /var/cache/squid directory manually.
41.3.2 Local DNS Server
Setting up a local DNS server makes sense even if it does not manage its own domain.
It then simply acts as a caching-only name server and is also able to resolve DNS re-
quests via the root name servers without requiring any special configuration (see Sec-
tion 33.3, "Starting the Name Server BIND" (page 626)). How this can be done depends
on whether you chose dynamic DNS during the configuration of the Internet connection.
