On a machine in a local network, I have in my /etc/network/interfaces

But after a power outage, my machine sometimes restarts while the
network isn't available yet. In this case, I can no longer ssh to
it. And I can't reboot it remotely.
How can I make pump (the DHCP client I'm using) to try again
periodically? I think I can write a script that tests if pump
is running (with the "ps" command) and can run this script by
cron. But is there a better way?
I use dhclient (I know you said in a different message in this thread
that you don't like it), which by default does a bunch of
DHCPDISCOVERS, and if they all fail, it then goes to sleep (for 5
minutes by default), and then begins the process again when it wakes
up. This behavior seems to be exactly what you need; unfortunately, I
don't know anything about pump.
