1. Re: Netdisco and Aruba Controllers (Muris)
--- Begin Message ---
Thanks Christian, im not really a coder, would it be possible if you composed
the different versions of the file then I can try see what works ?
It would be a win if we can get controllers reporting arpdata into netdisco if
this works.

Ok it looks like we're not getting much yet here.
Generally, there are two variant of SSH collector modules: one is using
ssh->capture, and the other one is using expect.
Currently we're on the capture method. This means that one simple
command is sent to the device. You can manually test this by doing:
ssh -l <username> <device> "show arp"
After the password prompt, this should output the full arp table.
If you need to pass in additional paging commands, you might be able to
shoehorn them in like so:
ssh -l <username> <device> "no paging ; show arp"
or maybe you can get lucky with one or more linebreaks, e.g. "no
paging\nshow arp\n\n".
This method mostly works on devices that run regular Linux, or something
very close to it.
If it doesn't work, you can try the expect method. Here, we don't send a
command in the SSH connection, but log in like a regular user and then
try to simulate all required keypresses. An example to look at is IOSXR:
<https://github.com/netdisco/netdisco/blob/master/lib/App/Netdisco/SSHCollector/Platform/IOSXR.pm>
You can rename this to Aruba.pm and see if you get there. It's important
to match the prompt correctly so we know when a command finished and we
can input stuff again. For your case it's probably
my $prompt = qr/#$/;
or even just $prompt = qr/#/;
Then replace the send() bits with your commands.
Finally you should get lines with arp entries with either method, then
the correct extraction loop for your example should be this:
foreach (@data) {
my ($proto, $ip, $mac, $if) = split(/\s+/);
if ($ip =~ m/(\d{1,3}\.){3}\d{1,3}/
&& $mac =~ m/([0-9a-f]{2}\:){5}[0-9a-f]{2}/i {
push(@arpentries, { ip => $ip, mac => $mac });
}
}
Good luck :)

> When you logon to the controller the output is as following as per below,
the annoying part is, you don’t see the full list initially, as on the bottom
you see this "--More-- (q) quit (u) pageup (/) search (n) repeat" you then have
to press the space bar to show the full list. To avoid this from happening,
once you logon, you have to issue "no paging" - then "show arp" to show the
full list. I think this should be the better way, the script first issuing "no
paging" then "show arp".
