Hi, thanks for the replies.
Yes I think its that stdin/out are not available to the service. The command is basically an `snmpwalk` that should run and return the result which my script deals with.
I've also tried using in/out pipes while getting another file to run the snmp, but the syswrite isnt sending anything.
Arghhh sorry for the vagueness I haven't the code with me atm.
Dave.
