How? Hi, Robert. The short answer is "yes". Just write your own startup script and use : start-stop-daemon --start --background --quiet --exec my_process start-stop-daemon --stop --quiet --exec my_process the --background should do the trick for processes that don't know how to daemonize. pgpNFe9exDECW.pgp Description: PGP signature

What we do here is : - install/configure SNMP on all our equipements (routers, switches, Linux and Windows servers too) - customize SNMP to add some more relevant information (like HD state for RAID arrays, which we can get through proprietary software from the RAID manufacturer) - use MRTG to chew the data and display something usable for a non-technical customer Works great so far.

Please don't use inetd / xinetd if you're looking for performance. Both spawn a new process each time there is an incoming request, which is a *huge* overhead. You definitely have to run qpopper (or any other POP daemon) as a standalone server. Other tips include : - recompiling qpopper with other options (no debugging, optimization) - reading http://www.eudora.com/qpopper/faq.html#performance and keep in mind that the number of mailboxes is not a significant number to compare performance.

Re: Remote Execution of Scripts
Hi Gene, You may want to try ssh and scp. - ssh can run a script on a remote computer - scp can copy a file to/from a remote computer Both of them are decently secure. You will need a sshd on the remote computer. If you want to fully automate the process (ie no password asked) you have to put your public ssh key in ~/.ssh/authorized_keys (check the man page). If you have to synchronize large files/directories I'd recommand using rsync -e ssh Another solution would be to use some centralized user base. Solutions could be based on LDAP, NFS mounts, MySQL server and many others. All depends on the software you're using to authenticate your users.
