Non-interactive CLI commands?
|
|
| Robert Kulagowski 2007-11-21, 1:11 pm |
| I'd like to pre-stage an IOS onto routers, and I use the following:
# copy http://ip.add.r.ess/filename flash:
However, this is an interactive command, and even though I've specified
the source and destination, IOS is still prompting me for source file
and destination file names. That would make my RANCID script more
complicated because now I'd have to program in the "expect" stuff as well.
The ftp-server command on my IOS seems to be gone.
TFTP is dog-slow on our high RTT links.
Am I missing some magic command?

| Are you using FTP to copy of HTTP?
With FTP, you would need to start by configuring the ftp username and
password in the general config, then issue:
# copy ftp://source filename url> flash:<destination filename> *enter*
And at the end of your script send an extra "enter/line feed" that will
actually confirm your command to the router.

Well, I'm using HTTP so that I don't need to provide login credentials
when I pull the IOS to the router.
The sticking point is that I want to make this script _very_ simple.
Using clogin from RANCID I can script non-interactive commands quite
easily, but to get the script to send extra CR is the issue, and I'd
prefer not to do that.
So, there's no "I-Know-What-Im-Doing-Do-What-I-Say" mode for the copy
command?

Sending CR isn't tricky, just add \n to the end of the line and that'll
send a CR after your command. I've some upgrade scripts for older
switches where I have to use this for deleting old content since they
don't support recursive deletes and prompt.
But this there is a better way:

Note the caveat though, you may not want it saved back to the
startup-config

| By issuing the
# copy http://<filename url> flash:<destination filename> *enter* +
*enter*
in your script, you should not have to enter additionnal information and
the router should go on its way. The second *enter*/line feed confirms
the command for you by responding automatically to the router
confirmation dialog for which "yes" is the default answer.
I don't think that should be too hard to implement, probably requirering
an extra "\n" or two in your script.

| In the script, provide the responses the system is looking for...
For example:
copy tftp flash
10.1.1.1
newios.bin
[include carriage returns to get it to copy...]

That's exactly what it was - I simply added in the \n into my clogin
command and increased the timeout. A simple for i in {foo} loop in bash
did the rest and if I'm not careful I might script myself out of a job!
