Hi Brent, Thanks for your reply. We use NIS. Here is the config followed by a ping example. (Same config as on the node that works as far as I can tell). This is Red Hat 7.3. unfiwcl3:/# cat /etc/hosts # Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1 unfiwcl3 localhost.localdomain localhost Here's how nsswitch.conf is configured: unfiwcl3:/# cat /etc/nsswitch.conf | grep hosts hosts: files nis dns Here is what is in the NIS hosts database: unfiwcl3:/# ypcat hosts | grep unfiwcl 172.24.150.91 unfiwcl1 172.24.150.92 unfiwcl2 172.24.150.93 unfiwcl3 172.24.150.94 unfiwcl4 ... and nothing in DNS ... unfiwcl3:/# host unfiwcl1 Host unfiwcl1 not found: 3(NXDOMAIN) unfiwcl3:/# host unfiwcl2 Host unfiwcl2 not found: 3(NXDOMAIN) unfiwcl3:/# host unfiwcl3 Host unfiwcl3 not found: 3(NXDOMAIN) unfiwcl3:/# host unfiwcl4 Host unfiwcl4 not found: 3(NXDOMAIN) Ping works: unfiwcl3:/# ping -c 1 unfiwcl1 PING unfiwcl1 (172.24.150.91) from 172.24.150.93 : 56(84) bytes of data. 64 bytes from unfiwcl1 (172.24.150.91): icmp_seq=1 ttl=64 time=0.152 ms --- unfiwcl1 ping statistics --- 1 packets transmitted, 1 received, 0% loss, time 0ms rtt min/avg/max/mdev = 0.152/0.152/0.152/0.000 ms unfiwcl3:/# ping -c 1 unfiwcl2 PING unfiwcl2 (172.24.150.92) from 172.24.150.93 : 56(84) bytes of data. 64 bytes from unfiwcl2 (172.24.150.92): icmp_seq=1 ttl=255 time=0.221 ms --- unfiwcl2 ping statistics --- 1 packets transmitted, 1 received, 0% loss, time 0ms rtt min/avg/max/mdev = 0.221/0.221/0.221/0.000 ms unfiwcl3:/# ping -c 1 unfiwcl3 PING unfiwcl3 (127.0.0.1) from 127.0.0.1 : 56(84) bytes of data. 64 bytes from unfiwcl3 (127.0.0.1): icmp_seq=1 ttl=255 time=0.094 ms --- unfiwcl3 ping statistics --- 1 packets transmitted, 1 received, 0% loss, time 0ms rtt min/avg/max/mdev = 0.094/0.094/0.094/0.000 ms unfiwcl3:/# ping -c 1 unfiwcl4 PING unfiwcl4 (172.24.150.94) from 172.24.150.93 : 56(84) bytes of data. 64 bytes from unfiwcl4 (172.24.150.94): icmp_seq=1 ttl=255 time=0.327 ms --- unfiwcl4 ping statistics --- 1 packets transmitted, 1 received, 0% loss, time 0ms rtt min/avg/max/mdev = 0.327/0.327/0.327/0.000 ms unfiwcl3:/# gexec -n 0 hostname 1 unfiwcl2 0 unfiwcl1 3 unfiwcl4 2 unfiwcl1 unfiwcl3:/# echo $GEXEC_SVRS unfiwcl1 unfiwcl2 unfiwcl3 unfiwcl4 unfiwcl3:/# Very strange... --Karl
