Hi
Thanks to everyone who responded to my question regarding the
/etc/netmasks file.
Most responses focussed on the fact that I had specified the base
address of the physical subnet rather than the VLAN my machine is
sitting on. So to this end, I'm going to test this change (the week
after next unfortunately), and report back to the list on success/failure.
i.e. Change /etc/netmasks from
131.104.91.0 255.255.255.224
-to-
131.104.91.96 225.255.255.224
Thanks to everyone
Scotty

Subject: Problems with /etc/netmasks on Solaris 8 system
Howdy
I'm having a problem with setting the correct values in /etc/netmasks on
a Solaris 8 system. We are moving it from a non-segmented subnet
(131.104.96.0) to an IP address (131.104.91.102) in a VLAN on the
131.104.91.0 subnet with a subnet mask of 255.255.255.224.
Old netmasks file
131.104.96.0 255.255.255.0
New netmasks file
131.104.91.0 255.255.255.224
The subnet mask is correct for the VLAN.
When I reboot the system after moving the ethernet cable to the new
subnet, I find the following settings for the interface using ifconfig:
IP address: 131.104.91.102 (correct)
Netmask: 255.255.0.0 (not correct, should be 255.255.255.224)
Broadcast: 131.104.255.255 (not correct, should be 131.104.91.127)
I manually corrected the problem by issuing the following command for
the interface eri0 after the system was rebooted
ifconfig eri0 netmask + broadcast +
This works, but I need these values set correctly when the system boots
up.
Any ideas? Is my syntax incorrect in the new /etc/netmasks file?
Thanks - will summarise to the list.
Scotty
