problem with ext script
list Operaciones
Hello Guy, i have a small problem, i create a script for check the raid status on Intel mainboards that use the command: dmraid -r So, when i run the script with xymon, show the error: ERROR: you must be root Do you know how can i fix it? Thank you very much.

Setuid the script Sudo the command in the script Run the script as root Take your pick. The first one is not secure in the least. The second one will require the xymon user to be in sudoers with permission to run the command without a password required. Or modifying the script to enter the password (which is not secure) The last is pretty easy, but would be running outside of the tasks.cfg probably in cron. And so you would need to call the script, most likely, with xymoncmd to get the environment right. Paul.

What I generally do in these cases is run the command from root's cron and
capture the output in a file that's readable by the Xymon user. Like so:
*/5 * * * * /sbin/dmraid -r >/tmp/dmraid.out && chgrp xymon /tmp/dmraid.out
&& chmod 644 /tmp/dmraid.out
Then in the script, in place of "dmraid -r" you just do "cat
/tmp/dmraid.out".

Why not just send the output to the server with the xymon command?

Yeah, I like this idea. The command can be sent as a supplementary client
command like so:
*/5 * * * * ~xymon/client/bin/xymoncmd sh -c '{ echo client/dmraid
$MACHINE; echo "[dmraid]"; /sbin/dmraid -r; } | $XYMON $XYMSRV @'
Then a script on the Xymon server can pull the dmraid output from the
client data like so:
#!/bin/sh
DMRAID=`$XYMON $XYMSRV "clientlog name.of.host section=dmraid"`
This strategy means that all of the heavy lifting is done on the Xymon
server, and the client needs only a fairly simple one-liner in a crontab.
Improvements to the script need only be applied to the Xymon server,
instead of having to perform updates to (for some of us) dozens or more
clients.
