You are literally allowing anyone to inject data to your
control-plane, it needs to be done right. I can immediately say you're
not doing it right because you're not passing binary and arguments
separately.
Wow, I'm biting my tongue Saku... but it's a direction, not final solution,
you've offered neither.
1) the OP said they preferred perl or php, so my interpretation of that means
they want to touch the code.
2) just because one can code doesn't mean they've thought of all options.
3) He said this was for his colleagues, which I interpret as not public access.
For internal use, why trouble oneself with the maintenance, excessive libraries, modules
and crud that another "installed" option would require if you don't need all
its features. As far as injecting anything unwanted, that is the point of only showing a
snippet... security is left to the OP/programmer.

Hi, all
can anyone recommend a free looking-glass tool
to run on my own NOC server for my own core routers?
My problem is finding a software that is preferably written in
Perl or PHP and
* not unmaintained for years
* breaking with current versions (5.24) of Perl
* only supporting telnet instead of ssh
* ...
I've been spending almost a day already chasing dead links
on historic sites like traceroute.org, downloading, configuring,
testing ...
So, any hints?
I had set up routerproxy to hand my less IOS-savvy colleagues a
tool to quickly check some things, but that one goes in the
"breaks with Perl 5.24" category ...
Thanks!

Hi Patrick,
If you prefer perl, are using a unix flavor, don't mind using a little
bourne shell within it, and are comfortable coding, write your own... the
relevant bits would look like:
$output = `( sleep 1;
echo $login; sleep 1;
echo $password; sleep 1;
echo term leng 0; sleep 1;
echo "** YOUR COMMAND **"; sleep 3;
echo "** 2nd COMMAND IF NEEDED **"; sleep 3;
echo exit; sleep 1;
) | /usr/bin/telnet $ip 2>&1`;
or
$output = `( sleep 1;
echo $login; sleep 1;
echo en; sleep 1;
echo $enable; sleep 1;
echo term leng 0; sleep 1;
echo "** YOUR COMMAND **"; sleep 3;
echo exit; sleep 1;
) | /usr/bin/telnet $ip 2>&1`;
Alternatively if you are only using IOS or IOS-XE, not IOS-XR, and have
netcat (nc) on your server I'd recommend using it in place of telnet as you
can run the commands without specifying the sleep needed for the responses
which greatly speeds up the program. There may be a way to make XR work
with it, but I've had no luck...
$output = `(
echo $login;
echo $password;
echo term leng 0;
echo "** YOUR COMMAND **";
echo exit;
) | /usr/bin/nc $ip 23 2>&1`;
Regards,
Scott
