From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.2) Gecko/20021120 Netscape/7.01 Description of problem: This isn't a redhat-config-network bug (at least I don't think it is), but I couldn't find anything more appropriate to class it as. After the box is up for a while, hostname resolution fails completely. The only way I've found to restore it is to restart networking (/etc/rc.d/init.d/network restart). I wasn't running nscd, so I've enabled that to see if it will resolve the problem. I haven't been able to determine if this happens after a certain time frame or after running a specific application, but it fails consistently, at least on a daily basis. Typically evolution will begin to complain of being unable to ping an imap host. This will go on for while, and then evolution will completely lose its connection to the mail server. I also can't use any network utilities (ping, traceroute, dig, nmap, etc.) If an strace will help, I can provide one. Version-Release number of selected component (if applicable): How reproducible: Didn't try Additional info:
dhcp?
please provide /etc/sysconfig/network-scripts/ifcfg-eth0 some /var/log/messages of interest?
To answer your questions: I using dhcp, but my IP address is fixed. IOW, I always get the same IP when the lease is renewed. cat /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0 BOOTPROTO=dhcp ONBOOT=yes egrep '(error|warn|fatal)' /var/log/messages Jan 22 16:26:13 utd49554 sysctl: error: permission denied on key 'net.ipv4.ip_forward' Jan 22 16:26:13 utd49554 sysctl: error: permission denied on key 'net.ipv4.conf.default.rp_filter' Jan 22 16:26:13 utd49554 sysctl: error: permission denied on key 'kernel.sysrq' Jan 22 16:26:13 utd49554 sysctl: error: permission denied on key 'kernel.core_uses_pid'
