bash question for quadz, or any programmers

[reaper]

Hi Quadz, seeing as you are a super nice guy I figured you might be able to help, this might be something you know of the top of your head.  My goal is to create automated backups of router/switch configuration files, and system images.  Changes are frequently made, and the last thing I want is to fix some switch without a config, when the switch does load-balancing, has a 100 vlans, and all that other fun stuff.

SNMP, and Expect, are the only options to do this (you cannot use Kron on Cisco routers for interactive commands).  So you can issue an SNMP get request, or automate what you would type with expect.

SNMP is probably the cleanest way to do this, since it's quicker, and doesn't actually log in to the router.  But I'm only doing this for five or so routers, and I don't know the OIDs to get the config, nor do I feel like using snmpwalk.  Either way the tools already created aren't to much help, as each router has unique OIDs, and they use expect, and snmp as is.  Plus .. this is supposed to be fun : )

What I have working (below), is an expect script connecting to a router, it then issues the commands to download the configs, and this script will be scheduled to run.  This works, my problem is - how do I close the damn window!@?

Since this script will be run often, and there will be similiar scripts, I can't have a million windows keep opening.  If it was a bash script, I believe I can just end the script with exit 0.  I tried programs to start cygwin in the system tray, but they don't seem to work, and that's not really what I wanna do. 

If I was to type expect within bash, I would get an expect prompt.  If I were to type exit I would go to bash, expect is a shell like bash, but with additional commands, and some bash commands not available.  I tried sending the encoded equivalent of control+D, and that did not work, it was fun, now I am really frustrated : /


#!/usr/bin/expect -f
#creating temporary file from bash date command
#the date will be used to give the router configuration files a unique name

exec  date +%y%d%h >/tmp/datesync.tmp
exec cat /tmp/datesync.tmp
set newtime [exec cat /tmp/datesync.tmp]


#grab config from router

spawn telnet 69.x.x.10
expect "Password:"
send "*******\r"
expect "xp>"
send "enable\r"
expect "Password:"
send "*********\r"
expect "xp#"
send "copy startup to tftp-server\r"
expect "tftp-server"
send "66.x.x.81\r"
expect "filename"
send "$newtime cabletron \r"
expect "xp#"
send "exit\r"
expect "xp>"
send "exit\r"


#delete temporary file
exec rm /tmp/datesync.tmp

exit 0

well I found a workaround, but it's not ideal (the windows don't instantly close), I schedule a job right after the scripts are run, which is just a .bat file that uses tskill bash.. but I want to close the windows at the end when they are open.  really i'd like to not have them visible when the scripts or run, but I did a man bash, and checked google.com and didn't know what was up : (.  there has to be a better way to do this.

still having problems with this.
my problem is after each expect script runs I want to close the cygwin window.

I think if I run a bash script, and call the expect script from within bash, it should work.

thanks you quadz@!!!!!!!

i was editing the shell script in notepad, and notepad was sending /r CR, not /n LF. is working now!
