Is it possible to set a timeout for rpcinfo?

I've created a script that checks the health of a piece of equipment out in the field by first establishing that it is pingable, and then parsing
log files to gather information. Today I realized that there are times where the equipment may be pingable, and will not show any
immediate issues in the logs, but will fail rpcinfo. I'd like to add an rpcinfo check to my script to alert who ever runs it that there is a
problem that isn't caught in any of the other tests.

My issue however is that the command rpcinfo doesn't seem to have a reasonable timeout before it fails. I don't want the script to hang
while the rpcinfo is being run. I know with ping I can lower the timeout (ping 10.90.0.11 1) but I can't find anything in the man pages
that shows me a similar way to work with rpc. I just want to do a simple "if rpc fails then echo this device has failed yadda yadda"

I'm working on a Solaris 10 box.

In case anyone cares, the script I'm working with is as follows (if you have any general advice on the script itself...by all means share.

Code:

No, rpcinfo does not have such an option. However you could easily write a watchdog script to kill your rpcinfo invocation after a certain time elapses.
