Saving switch configs with script

For how many times people forget to do a #write memory in their switches, I have come up with the idea to attempt writing a script to do it once a week and forcing it onto several hundred devices. Does anyone have any insight on this? It would be highly appreciated. Thanks!

Cisco Prime, Solarwinds, and Kiwi CatTools to name a few platforms that can accomplish this. I'd be more concerned about backing up the configs but again you can push out any commands you like via these as well

expect/TCL scripting can open this up for you, I cant find the thread where we were posting example scripts a year or so back, but I think I put mine in there.

you can open up a ssh connection run commands, parse the out puts and do as you like.

It is very easy once you get it, you run a command, tell it what to wait for (command prompt) and then what to do next. I have it going round all our old 3com devices backing them up to FTP server and then saving the running config. It also alerts me to changes.

Routemypacket listed some good programs that do it jsut as well (better) but for the thrill of a home made solution TCL is a great way to start

Yeah I'd use something like Rancid to pull the configs and back them up. A simple home made perl/python/etc. script could log in write mem and pull the config too. Plenty examples on the internet to get you started.

We are using SolarWinds Orion and it backs up configs nightly.

I think you could use kron to do that. Or you could have it back up your running-configs once a week.

We have Solarwinds, even though we haven't completely implemented it yet. We did before and the hard drive on the server died on us. I'll stick with that. Now we're working on getting the licenses taken care of. Thanks guys! Also, DevilWAH, is there a good online tutorial for tclsh specific to Cisco? I have found the foreach command to ping a range of ip addresses, but that's about it. I've been trying to download tcl from the tcl.tk website, but I'm not sure how to open the files on windows.

that has a basic script that will log on a switch and run a command, should not be to hard to change to do CISCO

Ok one more question. In all of your experiences as network admins/engineers/analysts/architects, what would be the ideal scripting language to learn?

Perl is what I've seen the most of by far. Python probably comes in second. Personally I've been trying to learn some Python and Ruby.

Kind of along the same lines...do y'all do 'reload in x' when making config changes in case a SNAFU happens?

Yup, but ideally I am not making those kinds of changes during the standard work-day.

By "those kinds of changes" I mean something so major that I lose connectivity or reloading is faster than undoing all of my work.
