[SunHELP] Collision Errors

[Howard Hurst]

I get the following output from netstat -ia. I don't really know much about
the netstat command (the man pages don't really explain what the output
means).

I've tidied up the output of the command so hopefully it is easier to read.

# netstat -ia

This server is a DNS/NIS Master and hosts over half of the companies email
accounts. There are hundreds of PC's running Win95 and NT connecting to this
server and about 40 or so NIS clients.

The NIS clients don't show any collisions when I run this command. Could it
be a network card issue? I'm of the opinion that they either work or not!

I strongly suspect that it is a badly configured router. The default router
used by this server is not used by any other server on the network. But
before I go moaning to the network administrator I'd like some proof to show
him! The only "ammo" I have may or may not be related to this issue -
sometimes the older servers bind to the NIS Slave, rather than the Master.
(If I had a spare server I'd configure it to run with the suspect default
router - unfortunately I can't do that right now.)

Does anyone know of some easy to install software (for Sol 2.6) that may
highlight the problem I am having? Or, alternatively, a site which has a
good explanation of the output of the netstat command?

Cheers,

Howard
