Ok... I can't figure this one out... I've just upgraded my Squid to 2.5/STABLE11 with yum (previously was using 2.5/STABLE6). And this problem started. I receive this message on the clients browsers: The requested URL could not be retrieved ----------------------------------------- While trying to retrieve the URL: http://www.google.com.br/ The following error was encountered: Unable to determine IP address from host name for www.google.com.br The dnsserver returned: Timeout This means that: The cache was not able to resolve the hostname presented in the URL. Check if the address is correct. Your cache administrator is xxx@xxxxxxxx ----------------------------------------- Generated Wed, 07 Jun 2006 05:01:08 GMT by netradio.com.br (squid/2.5.STABLE11) The weirdest thing is that I can browse with the server. And worst... Everything returns to normal when I restart squid service (ex: /etc/rc.d/init.d/squid restart) So this means it has to be a small glitch. I can't be related to network problems. If it were network problems, by restarting squid, things would continue to go wrong right? Has anyone gone through this?
