I asked about a problem getting the netmask to set correctly on reboot
in Solaris 10. Thanks to all that replied. I believe that I made a false
assumption of what the netmask *should* be, based on another server that
turns out not to be on the same network. Thus, it appears to be my

However, I rec'd a number of good suggestions. Most people said this
hadn't changed from Solaris 9 to Solaris 10. It was also noted that I
should have included examples - apologies, had trouble sanitizing info
and hoped this was an easy and obvious change in Solaris 10. Comments

* "I had the same problem and I fixed it by adding the netmask on the
/etc/hostname.hme0 file. Here is an example: netmask + broadcast + up"
* Check the links from /etc/netmasks to /etc/inet/netmasks, and
/etc/hosts to /etc/inet/hosts, and double-check syntax in files
* Check the network number in /etc/netmasks 
* Make sure you have the same entries as /etc/hosts (sym link to
/etc/inet/hosts)  in /etc/inet/ipnodes. "Used to be for IPV6 only.
Compulsory on Solaris 10 for IPV4, too, nowadays."
* "I notice that Solaris 10 is very strict about network definition,
e.g., we had an old definition like
...which had worked before, but Sol10 rejected it because 10.241.132
isn't (strictly speaking) a network."
