Edit the /etc/ssh/sshd_config file and change the value "Permitrootlogin" to "yes" in the server box
then u can do the rest using the client box

/me coughs ... suchi, you're kidding, right?


hueofwind: instead of making a shell-script
suid create a sudoers file and give the sysauto
user permission to run /etc/init.d/dhcpd restart
password-less (again with your ssh-mechanism).


And even though I know you didn't like my suggestion...
How about running a test (check whether file was modified
in the last six minutes every five minutes from cron and
if it was restart the dhcp-daemon).

newfile.sh
Code:
#!/bin/bash
find /etc -ctime -6 -iname dhcpd.conf -exec /etc/init.d/dhcpd restart \;
and a crontab entry:
*/5 * * * * newfile.sh



Cheers,
Tink

It's a shell script.
The shell itself is not setuid.

Run chmod +s /bin/bash and it'll work just dandy for you!

DON'T. :-)

Spend five minutes setting up the complicated remote execution environment,
and then all the logical flow of stopping and restarting the two servers and
getting the file across is under the control of one process.

Is it necessary to have two DHCP servers? In general they hate each other.
You might look into setting B to watch A, and only launch dhcpd if the service
on A fails.

If they're on seperate subnets, you could also look at using a relay instead.

Good luck with it.
