Hi All, I have 2 servers: hostA: RedHat Linux 2.4.21-40.EL hostB: HP-UX 10.20 >From hostA, I can't lookup hostB even though I put its entry in /etc/hosts file. root@hostA:/> host hostB Host hostB not found: 3(NXDOMAIN) Nsswitch.conf is configured to search file first: root@hostA:/> grep ^hosts /etc/nsswitch.conf hosts: files dns But ping works: root@hostA:/> ping hostB PING hostB.domain (<hostB's IP>) 56(84) bytes of data. 64 bytes from hostB.domain (<hostB's IP>): icmp_seq=0 ttl=254 time=0.208 ms 64 bytes from hostB.domain (<hostB's IP>): icmp_seq=1 ttl=254 time=0.231 ms --- hostB.domain ping statistics --- 2 packets transmitted, 2 received, 0% packet loss, time 1011ms rtt min/avg/max/mdev = 0.208/0.219/0.231/0.018 ms, pipe 2 Can anybody tell me why is that so, and how to solve it such that host lookup can work just like nslookup in HP Unix?
