Solaris 10 netmask

[reinstalled]

Hi,

Have an issue with a Solaris 10 SPARC box that
whenever it reboots it sets an 8 bit mask instead of
a 16 bit as specified in /etc/netmasks

Is there a config file I'm missing somewhere that's over riding /etc/netmasks?

Do I need to use sys-unconfig?

Thanks

what does your netmask in /etc/netmasks look like?

also,

take a look at the following file, I have had these give me problems every once in a while.

/etc/inet/netmasks (in theory, it is suppose to get what ever is assigned to /etc/netmasks, BUT every once in a while it has a hiccup and does not do like it is suppose to.)

I have had this happen for /etc/inet/hosts too after making a change to /etc/hosts

Thanks for the response.

I did think to look at /etc/inet/netmasks and it looks good, meaning identical as it should. I've the same issue before with hosts as well.

entry is:

10.2.234.0 255.255.0.0

I was thinking with the range that maybe I need to specify the host as well in netmasks?

nsswitch.conf showing files first for "netmask" ?

you should not need to specify the host in the netmasks file.

is your defaultrouter set correctly? /etc/defaultrouter

I know this probably is not the issue, but..just throwing idears out ...

you may look at you /etc/hostname.###

make sure it is setup correctly, if it is not, It can affect how it brings up the interface after reboot

Looks ok to me:

netmasks: files

defaultrouter looks good but a different net than the host

host 10.2.234.0
defaultrouter 10.2.240.x

hmm, shouldn't it be on the same network as the host. I've never seen that before...interesting

 

[reinstalled]

Trying to remember way back to class....

I think since it's masked as /16 bit it is on the same net.

Still looking. I know the "correct" way to make changes to Networking items such as netmask, should be done with the sys-unconfig command. Still don't know what possible other files that command would touch but I may try it. Problem is that it's at a remote client site and not sure if it's hooked to a console....

The entry in /etc/netmasks should read:

10.2.0.0      255.255.0.0
