Add route to solaris10
Hi need to add 2 routes, one on each server.
I know the route add comand but I have always been given the parameters to put in.

I need a route in each of the 2 following servers to be able to ping and ssh between them. But how do i know which netmask to put in the route add command ?
In server4 i would like to use interface ce0
in server3 i would like to use interface ce1

I would apreciate very much if some one could explain how to do it
beacuse it`s a mystery to me.
Also the actual route add comand would be apreciated since im running out of time.

Below is actual config that does not permit ping between servers.
server4
Code:
netstat -nrv

Thanks to every one that takes time to respond.

you need to ask your network person for the correct netmask and gateway.

You need the correct gateway to connect to the different vlan.
Most times this is a router or a system with router functions.

From the routing table of server 3, I can see that it already has a route to the server4 ce0 interface.

10.21.125.32 255.255.255.224 10.6.129.1 1500* 0 1 UG 1 0

10.21.125.32 => 10. 21.125.0010 0000
255.255.255.224 => 255.255.255.1110 0000
-----------------------------------------------------------------
From the last 5 host bits, we should know that the network 10.21.125.32/27 implies that the host IPs are from 10.21.125.32 to 10.21.125.63.

So You only need to add a route server4.

server 4
route add host 10.6.129.33 <appropriate gateway>

from the output you have provided its not clear what the gateway should be. If you can provide a small network diagram(if not full picture, atleast the one that shows cabling between the 2 servers) I might be able to help.

Your ping is failing now because the packets from server3 will reach server4 but server4 will not know how to respond as it does not have a route to server3.

good luck

Thanks for your input.

The route 10.21.125.32 255.255.255.224 10.6.129.1 in server 3 I put it there but Im not sure its correct I just took the min host as the gateway
and for netmask i guessed that i should use the same as for the ce0 interface of server3.

In server 4 I also have 2 networks for the gateway shouldnt i have to shoose any of the
min host for one of theese interfaces, or is it possible to have the gateway to be some other address.? I did try with
Code:
route add -net 10.21.125.32 -netmask 255.255.255.0 -gateway 10.6.129.1

but that did not work.

Thanks

1) If you added this entry

code:
10.21.125.32 255.255.255.224 10.6.129.1 1500* 0 1 UG 1 0

You can use a 255.255.255.255 mask as, It wont hurt and you can get connectivity to the other server.

2) I am not sure what you mean by 'min host'.
3) On server4, you should use a gateway based on how your network is setup. I am not sure how your network looks. So I really cant tell you anything about that.

Hi. by min host I meant the first host in each net.
I belive that as a rule of thumb the first host in each net is a gateway ?
