There was probably a lot more that it was designed for. Plus one of the first things to appear in google: "Despite its acronym, SNMP is not exactly simple! In fact, it never ceases to amaze me how much of a black art implementing and using SNMP" I don't necessarily want to avoid it, it's just got that 'can-of-worms' sort of feel to it and I'm hoping I only need the little script in bash. Or at least I did until I realised I'd have to tie ping together with dyndns.org and smsclient. Possibly a brainer. I mean, not a no-brainer. -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe". Trouble?

With pipes, "variable substitution" redirection, file io, all manner of control operators, dialog/zenity, etc, etc. If (as I suspect) you're new to bash programming, doing this yourself will open you up to a world of possibilities you barely knew existed. -- Dissent is patriotic, remember? -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".

I wouldn't say I'm new to it, but I'm not experienced. I write little snippets every now and again and edit system startup files etc. This is certainly a challenge though. I guess if I can interface dyndns.org and smsclient relatively simply with options you mention, I'll probably manage it. I might also put a check in there for other protocols like http, just in case ping happens to be the last protocol standing when the machine or connection is about to keel over!

http://www.hcst.net/~vogelke/src/ishostup/ These scripts are good for exactly one thing: sending me (or someone) a message if a given piece of hardware at a given IP address stops responding for more than a minute or so. They rely on fping and regular email. -- Karl Vogel I don't speak for the USAF or my company He kept saying I didn't listen to him... or something. --Tritchen Smith -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".
