first off, i'm not really sure which services you are trying to restart. i think what you are saying is that instead of using ssh to get into the remote machine and execute a monitor, the ex-guru was using inetd to execute the scripts. it is possible to use inetd in this manner. there are a few things to do if you want to add more monitors via inetd -- i'll add a way to check df -k on a machine by telnetting to port 600:
in /etc/services add: dftest 600/tcp in /etc/inetd.conf add: dftest stream tcp nowait root /usr/sbin/tcpd df -k now restart or HUP inetd and telnet to port 600 on that machine. you ought to get back an exact listing of a df -k. running other services this way can be handy, but be careful of security. you'll still have to write mon tools to parse the output to alert you. now, the downside to writing monitors this way is that you must go down to each machine that you want to monitor and set up each inetd service. i'm a bit impatient, and tend to make things easier on myself. by writing the df -k as a stand alone ssh script i save myself from having to maunaly configure a bunch of boxes, and it is easier to put into the mon-contrib for others to use. i hope this helps. -Tom Scanlan OpenReach, Inc.
