Basic Solaris static routing

UNIX Solaris
1

Hi All, :(:confused:

I have scoured the web and can't find this anywhere.

What I am trying to do is set up a static route through an available gateway on a server, and then test connectivity through TELNET.

I have done this on AIX (I already had this procedure).
On AIX I would use SMIT. In this example I had the following info.

Destination IP: 167.210.153.38
Default Gateway: 130.103.18.1
Net Mask: 255.255.254.0
Network Interface: 130.103.19.158

So using SMIT I created this command, which could be run via cmd line:

chdev -l inet0 -a route=net, -hopcount, 0, -netmask, 255.255.254.0, -if, en0,,,,167.210.153.38, 130.103,18.1

then after the static route is set up:

# telnet 167.210.153.38

would give a response to prove it worked.

        • *

Now, I just have to do the same thing on a number of Solaris boxes.

I assume the best approach would be to add a line to /etc/gateways, something like:

net 167.210.153.38/255.255.254.0 gateway 130.103.19.158 metric 0 passive

Since I have no SMIT or interface tool I can use, I am pretty much limited to having to figure out exactly where everything is supposed to be first shot.

Does anyone know how to this?

Thanks much

I am not sure how exactly to get the available gateway information on Solaris.
For example if I do this on Solaris:

# netstat -in

I get:

Name Mtu Net/Dest Address Ipkts Ierrs Opkts Oerrs Collis Queue
lo0 8232 127.0.0.0 127.0.0.1 57935224 0 57935224 0 0 0
fjgi0 1500 159.202.145.128 159.202.145.244 28530586 0 3954426 0 0 0
fjgi4 1500 192.168.40.0 192.168.40.55 15371263 0 9248059 0 1657923 0
hme0 1500 130.103.18.0 130.103.19.190 5747738 0 8868158 0 0 0

Whereas on AIX, if I do netstat -in, I would get:

Name Mtu Network Address Ipkts Ierrs Opkts Oerrs Coll
en0 1500 link#2 6e.c.50.1.f0.4 5273447 0 3880490 0 0
en0 1500 130.103.18 130.103.19.234 5273447 0 3880490 0 0
en1 1500 link#3 6e.c.50.1.f0.5 8294404 0 6688212 0 0
en1 1500 192.168.145 192.168.145.129 8294404 0 6688212 0 0
en1 1500 159.202.145 159.202.145.237 8294404 0 6688212 0 0
en1 1500 159.202.145 159.202.145.252 8294404 0 6688212 0 0
lo0 16896 link#1 5431023 0 5437550 0 0
lo0 16896 127 127.0.0.1 5431023 0 5437550 0 0
lo0 16896 ::1 5431023 0 5437550 0 0

Where I imagine I can see en0 having 130.103.18.1 as an available gateway. (I don't have this problem on AIX, because I can just get it out of SMIT)

Is there anywhere where anyone has ever written this down?
Surely if Solaris proves to be a real pain, there will be less of them in our future.

Thanks for any help.

for routes use the file /etc/inet/routes... view routes with:

"netstat -rn"

hth,

DukeNuke,

This file is blank on my Solaris box.
I am unclear as to what you mean.
Do you mean use /etc/inet/routes in place of /etc/gateways?

Is there a writeup on this procedure anywhere in cyberspace as to how to do it?

Surely people learned this from somewhere.

enter the routes in the file /etc/inet/routes like this:

net "network" "router"

example:
net 192.168.0.0/24 192.168.0.254

I hate to enervate the point, but I still can't tell from that how one translates the output of the 'netstat -in' command to an entry for this line.

For example: (# netstat -in)

Name Mtu Net/Dest Address Ipkts Ierrs Opkts Oerrs Collis Queue
lo0 8232 127.0.0.0 127.0.0.1 57935224 0 57935224 0 0 0
fjgi0 1500 159.202.145.128 159.202.145.244 28530586 0 3954426 0 0 0
fjgi4 1500 192.168.40.0 192.168.40.55 15371263 0 9248059 0 1657923 0
hme0 1500 130.103.18.0 130.103.19.190 5747738 0 8868158 0 0 0

I am guessing wildly here. If my destination address to static route TO is 167.210.153.38, then it looks to me like the available gateway I want is 130.103.18.0.
I don't see any en0 interface like there was on the AIX box, but I do recognize the 130.103.18 prefix, which I saw dozens of on the AIX side using SMIT (if I saw 130.103.20.0 for instance, that would be the available gateway I would use).

So the line I would enter would be:

net 130.103.18.1/255.255.255.0 167.210.153.38

or

net 130.103.18.1/255.255.254.0 167.210.153.38

Depending on what the network mask is.
I know that 255.255.255.0 can be expressed simply as '24':

http://www.ingate.com/files/422/fwmanual-en/xa11944.html

At that point I would assume a

# telnet 167.210.153.38 60000

Would respond if it worked.
But I am not sure how one gets the correct network mask needed to place in this file from the output above.

? ? ?

Okay, the command is netstat -rn, not nestat -in.

I will learn how to do a static route, if it's the last thing I do in this job.
Beware, networking gurus! Your ivory tower is under siege, and the idiots are coming.
