Here's the basic problem:

> hosts: files dns

Items to note are that the PTR record for 10.108.20.97 returns
adminbox.MIS.mycompany.com (note caps). The hosts file "should"
shortcut the lookup and simply return "adminbox" on the ping.
To make it even more fun, solaris appears to be selective on when it
does this:
> : sol10; grep 10.108.22.78 /etc/inet/hosts
> 10.108.22.78 laptop laptop.mis.mycompany.com
> : sol10; host 10.108.22.78
> 78.22.108.10.in-addr.arpa domain name pointer 0A6C164E.mis.mycompany.com.
> : sol10; ping -s 10.108.22.78
> PING 10.108.22.78: 56 data bytes
> 64 bytes from laptop (10.108.22.78): icmp_seq=0. time=0.716 ms
> ^C
> ----10.108.22.78 PING Statistics----
> 1 packets transmitted, 1 packets received, 0% packet loss
> round-trip (ms) min/avg/max/stddev = 0.716/0.716/0.716/NaN
I've tried restarting nscd, I've even rebooted the sol10 box.
This is rather odd.
