Maybe someone has an idea? Recently started having a problem where "host $SHORTNAME" works, "nslookup $SHORTNAME" works, but ping/ssh/ftp/rsync don't?
It works for some short hostnames consistently, but for other hosts does not work. Stopping nscd seems to fix the problem completely? Restarted nscd and it still worked. Why nscd has crappy problem? Return "unknown host" or "Name or service not known" Had a RedHat 7.2 box working just fine. Had been up and running for 120 days. Installed ALL eratta and put in faster CPU and added some memory. Rebooted. Running standard RED HAT Rpm stuff for everything. Nothing special. All other servers (130 of them) working just fine. static IP address 172.17.3.100 eth0 Link encap:Ethernet HWaddr 00:10:6F:00:4C:67 inet addr:172.17.3.100 Bcast:172.17.3.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:145852 errors:0 dropped:0 overruns:0 frame:0 TX packets:134415 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:100 RX bytes:17704022 (16.8 Mb) TX bytes:69097464 (65.8 Mb) Interrupt:9 Base address:0xf000 [root@mis-unix log]# netstat -nr Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface 172.17.3.0 0.0.0.0 255.255.255.0 U 40 0 0 eth0 127.0.0.0 0.0.0.0 255.0.0.0 U 40 0 0 lo 0.0.0.0 172.17.3.1 0.0.0.0 UG 40 0 0 eth0 [root@mis-unix log]# cat /etc/resolv.conf nameserver 172.17.3.47 nameserver 172.17.3.253 search reston.tnsi.com. tnsi.com. red.tnsi.com. blue.tnsi.com. chantilly.tnsi.com. corp.tnsi.com. options ndots:3 timeout:6 attempts:2 [root@mis-unix log]# cat /etc/nsswitch.conf | grep -v "^#" passwd: files shadow: files group: files hosts: dns files bootparams: files ethers: files netmasks: files networks: files protocols: files rpc: files services: files netgroup: files publickey: automount: files aliases: files [root@mis-unix log]# cat /etc/host.conf order hosts,bind [root@mis-unix log]# host kurt kurt.blue.tnsi.com has address 172.17.7.100 [root@mis-unix log]# nslookup kurt Note: nslookup is deprecated and may be removed from future releases.
