Gateway

Hi all,

Just now i had change the gateway for a server
Code:
Go to  /etc/defaultrouter, change to 10.86.33.1
route  delete default 10.86.39.222
route  add default 10.86.33.1

now cannot telnet to the server already..
any idea?

Hard to tell without more clues. 10.86.33.1 might simply be unreachable.

ya.. i had solve the problem.
the mainly problem is i remote to the server.
so when i run "route delete default 10.86.39.222"
it already delete the gateway, and the network disconnect between me and server.

thus, i need to use a console cable to control the server and change the gateway.

Or you could add new gateway first, then delete old one. There can be multiple default gateways configured in Solaris, so for a moment you will have two.

Might be incorrect/missing netmask settings.
Are your networks declared in the netmasks database ?
