Hallo, Amos, Du meintest am 25.01.12: >> If I changed the entry in /etc/resolv.conf then, Is there need to >> reload/reconfigure the squid? > Yes. Squid does not monitor the configuration files for changes. It's > on the feature wishlist, but nobody has had enough interest to code > up a small background ticker event to do the checks. I use "incron" from Lukas Aiken, http://inotify.aiken.cz with the file "/etc/incron.d/squid" with the contents /etc/resolv.conf IN_MODIFY squid -k reconfigure That means: if "/etc/resolv.conf" is modified then run "squid -k reconfigure". There are some other programs which also work with "inotify" - maybe it's hard for a "squid" developper to look for the special routine(s) on a special target machine. "incron" hasn't changed the last two years - don't know if Lukas still works on it. But the program doesn't seem to need changes ... Viele Gruesse! Helmut
