IP Networking

WE are running Unix - Solaris 2.6, we create a subnet. In the windows enviroment we are able to add a static route by using
route add -p 172.16.10.0 mask 255.255.255.0 172.16.17.224, but when we add the route in Solaris as
route add -net 172.16.10.0 255.255.255.0 172.16.17.224, we receive an error message that says
add net 172.16.10.0: gateway 255.255.255.0: network is unreachable.

The 172.16.17.224 is a router used as the gateway to the subnets, however we are to ping 172.16.17.224 from Solaris.

Any idea why we cannot add a route to that subnet in Solaris 2.6?

I solved my problem by using
route add -net 172.16.16.0 172.16.17.224
leaving the subnet mask out and it work fine.

man route should have shown you the correct possition of your gateway and subnetmask

Normaly you define your broacast as 0xffffff00 in solaris.

It's ok, always confusing

In my organisation, I have a private LAN (10.x.x.x) and a public LAN (172.x.x.x).
Machine in private LAN need to grep CAD license from public LAN.
I use the same method as what Cassy did on my Sun Machine and the settings is gone once the system reboots.

Any suggestion, how can I set the settings perm.

do we use the same methd on HPUX as well?

You can add a new startup script to /etc/rc2.d/ or /etc/rc3.d/ - see creating and using init.d/rc*.d startup scripts

I used to use some thing like
route add 10.99.101.0/24 10.99.101.1

On solaris you can add it in /etc/rc2.d/S72inetsvc or you can create a new script in the startup script directories
