The clearest way to fix the problem is to use dns_nameservers option in the squid.conf file and to put there servers that are in the resolv.conf file. This is not a bug of squid because the squid can't affect resolv.conf creation and the one provides resources to fix the problem. These findings could be read from /var/log/squid/cache.log file.

I forgot say in my case it is standard wired lan connection, not WiFi. And I agree, what static interface configuration may solve problem but, in any case, it is only workaround, which does not solve problem itself. > The problem with NetworkManager is that it is user driven and very dynamic, > which in many cases means Squid won't be able to run until a user logs on to > the console, and even if NetworkManager is set to enable some network by > default users can easily distupt this by just logging in.. Futhermore, may say what it is default installation of Fedora 10. And NetworkManager DO NOT used to setup connection, it is just start bu default. I think we even don't try in squid handle any user network settings on the fly, but start and work after system restart it MUST. I also may note what network function properly just after login - no any steeps needed. May be we need file bug on NetworkManager to its behavior concerned /etc/resolv.conf recretion when it is not needed? I even can't imaginate for what may be needed empty it (it is not altered, it is empty according to squid log).

When the system boots it brings up the Ethernet interfaces (/etc/init.d/network), which then get reconfigured again when NetworkManager starts, including clearing /etc/resolv.conf.

There is a clear indication: NetworkManager (man NetworkManager) will execute scripts in /etc/NetworkManager/dispatcher.d on network events. The apps/services need to stop being stupid. Network isn't always up. They need to either handle network state themselves internally, or be restarted when the network goes up or down. So putting a dispatcher script in /etc/NetworkManager/dispatcher.d for squid that simply restarts squid when an interface goes up or down should be sufficient for you here. That script should ship with the squid package. Again, 'man NetworkManager' will tell you absolutely everything you need to know for a dispatcher script, and you can find examples there already installed by initscripts. initscripts even installs a 00-netreport dispatcher that will notify programs that have requested information on network changes that something has occurred. Maybe squid should use that instead. > For Ethernet interfaces the fix is as simple as starting system-config-network > and unchecking the "Controlled by NetworkManager" checkbox on the interface(s) > in question.

The solution is to fix the services to be responsive to *all* situations including situations where networking is sometimes transient. That implies restarting the services when the network is up. Or, you could try NETWORKWAIT=yes in /etc/sysconfig/network which will force bootup to block until a network interface is up, or a timeout has occurred. > But I agree it's partially a NetworkManager misfeature.

If you've turned it on yourself, then of course NM and the network service will both try to do the same thing. So we need to figure out why its clearing resolv.conf. Have you put DNS1/DNS2/DNS3 into your /etc/sysconfig/network-scripts/ifcfg-eth0 file like the blank resolv.conf may have told you about? resolv.conf is *transient* and changes depending on what connections are brought up (even if NetworkManager is not turned on!!); just using 'ifup eth0' if eth0 uses DHCP will clear your resolv.conf. Thus, for your static IP connections, there needs to be some canonical location for the DNS servers and search domains, and that canonical location is the ifcfg file for that interface.

Both NetworkManager and network is on by default from what I can tell. Did not make any network configuration at all, left all at the default. Only manual configuration done after the install was: yum install squid chkconfig squid on reboot. Squid starts very very late in the bootup, long after both network and NetworkManager. network sets up eth0 properly using DHCP, which populates /etc/resolv.conf. NetworkManager service starts a little later, but bootup by default does not wait for it to finish configuring the interfaces. When Squid starts shortly after NetworkManager /etc/resolv.conf is empty. Running system-config-network and configuring eth0 to not be controlled by NetworkManager "cures" the problem. But I see your point about adding NetworkManager integration to the Squid package. I'll try to allocate some time for that in next package maintenance cycle in a few days.
