It's not bad. I would use -host instead of -net and -netmask, and it will fail if the DHCP server ever changes its address, but what you are doing is is working and fairly likely to stay that way. > I have to > issue this statement whenever the dhclient is restarted.

If you want something more elegant, you could specify a script for one of the dhclient-script(8) hooks, and put the route in there. You would be able to refer to the interface and server address by variables which dhclient-script provides... -- Lowell Gilbert, embedded/networking software engineer, Boston area http://be-well.ilk.org/~lowell/
