[Sunhelp] Configuring Networking

[Wayne Schmieder]

Try the following command netstat -nr.  This should show you if you have a 
default router configured.  You'll see something like this in the table.

default              148.80.130.9          UG       0 114293

Basically what this line says is the IP address of the default gateway and 
that it is a gateway  (UG) that is up.

If you don't see this use the following as root.  route add default x.x.x.x 
1

x.x.x.x being the IP address of your default gateway or router. The one is 
the metric.

Any host specific routes you add, i.e. route to machine x via netxhop route 
y, are also added using the route add command.  Be sure to configure 
/etc/rc2.d/S72inetsvc so that it contains a line such as /usr/sbin/route 
add destination x gateway y 1  . Otherwise any host or net specific routes 
will be lost after a re - boot.

If this is correct use traceroute to an address you are trying to reach. 
 You should see it go to you default router as part of the path.  If your 
getting to your default router, and not further, the router could be set up 
to filter what machines are allowed outside access.  If this is the case 
you may have to add a permit statement in the router filters.  Procedures 
for this depend on the router.  This may sound too obvious, but make sure 
that the machine you are attempting to ping can be pinged from other hosts 
on the same sub-net.  For security reasons, some administrators do not 
allow you to ping from an outside machine.

Hope this helps.

A long time ago, in a galaxy far, far way, someone said...

Did you try rebooting?  (Yes, I know this isn't Windows, but unless you've
had training in Solaris, it might be the best way to get something to
work)

A good place to start would the the output of the command 'netstat -r' -
that command prints out the kernel routing table.

Sorry, can't help there.
