[rancid] Assistance creating a perl module to use with ZPE Systems NodegridOS Devices

[Mick O'Donovan]

Hi Heas, all,

I'm struggling with an issue in trying to get some outputs from our ZPE estate of Out of Band devices using RANCID. What I have tried to do thus far is as follows:

1. Set credentials for my devices in .cloginrc
2. Cloned both clogin and rancid files in /var/lib/rancid/bin to zpelogin and zperancid respectively (just for separation)
 - Here's the diff of the files:
rancid at rancid-staging:~/bin$ diff clogin zpelogin
1052,1072c1052,1072
<     if { $do_command || $do_script } {
< 	if { [string compare "extreme" "$platform"] } {
< 	    # If the prompt is (enable), then we are on a switch and the
< 	    # command is "set length 0"; otherwise its "terminal length 0".
< 	    if [regexp -- ".*> .*enable" "$prompt"] {
< 		send "set length 0\r"
< 		expect -re $prompt  	{}
< 		send "set width 132\r"
< 		expect -re $prompt	{}
< 		send "set logging session disable\r"
< 	    } else {
< 		send "terminal length 0\r"
< 		expect -re $prompt  	{}
< 		send "terminal width 132\r"
< 	    }
< 	    expect -re $prompt		{}
< 	} else {
< 	    send "disable clipaging\r"
< 	    expect -re $prompt		{}
< 	}
<     }

^^^ so essentially I've removed the cisco specific terminal length setting, etc

rancid at rancid-staging:~/bin$ diff rancid zperancid
140a141,143
> # I don't care if it sees "exit"
> $clean_run = 1;

^^^ It was recommended to me several weeks back to make this change but I can't for the life of me remember why.

3. edited /etc/rancid/rancid.types.[conf/base] to include the following lines

zpe;script;zperancid -t zpe
zpe;login;zpelogin
zpe;module;eos
zpe;inloop;eos::inloop
zpe;command;eos::ShowSoftware;show system/about
zpe;command;eos::ShowConfig;export_settings

^^^ the above trying the eos.pm module

When I run some debug against a host I receive the following:

rancid -d -t zpe <redacted>
loadtype: device type zpe
loadtype: found device type zpe in /etc/rancid/rancid.types.base
executing zpelogin -t 90 -c"show system/about;export_settings;show_settings" <redacted>
PROMPT MATCH: \[heanet@<redacted> /\]#
HIT COMMAND:[heanet@<redacted> /]#  show system/about
    In ShowSoftware: [heanet@<redacted> /]#  show system/about
<redacted>: missed cmd(s): export_settings,show_settings
<redacted>: missed cmd(s): export_settings,show_settings
<redacted>: End of run not found
<redacted>: End of run not found

My reading of the above is that the module in question can properly understand the output received from the "show system/about" command and therefore stops and doesn't run the subsequent command. I would like to either get this sorted using pre-existing modules (probably not possible) or create a new perl module specific to zpe (happy to share with the community for others to use if needed).

For completeness, he's a snip of the outputs received in each of the commands I'm looking to run:

This is something that has been bugging me for a while so any help would be much appreciated!
