Accidently missed the proper rancid-dicuss email in my first answer, sorry for that.

As seen in the following posts I got it to work. But I will post those details here if someone else has the same problem and runs into this thread. This is probably not the best solution nor good practice. But it works for us so I'll keep it like this, there are funnier things to do in life then mess with rancid configs. =)

 In addition to the other posts with the solution to my problem this is how my config looks like:


add method jg-dsw01 ssh
add autoenable jg-dsw01 0
add user jg-dsw01 username
add password jg-dsw01 password

neo-dell;command;nxos::ShowVersion;show version
neo-dell;command;nxos::WriteTerm;show running-config

And the changes I've done in neo-jgdsw01-trancid compared to vanilla trancid was described in previous post. Without those changed it will NOT work.

So, with all this it works. Probably not correct. But it works and life goes on. =)

> I've concluded that tlogin works fine for the login procedure, I've landed in that since that one has the same WHILE as described in the post above. Making it somewhat easier for me to modify:
> bin/tlogin jg-dsw01
> jg-dsw01
> spawn ssh -x -l rancid jg-dsw01
> rancid at jg-dsw01's password:
> JG-DSW01>enable
> JG-DSW01#
> JG-DSW01#
> I think the problem boils down to the exit "procedure" here.
> JG-DSW01#exit
> JG-DSW01>exitConnection to jg-dsw01 closed.
> When looking at the hostname.raw it looks like this:
> eula-consent support-assist reject
> eula-consent hiveagent reject
> exit
> JG-DSW01#exit
> JG-DSW01>exitConnection to jg-dsw01 closed.^M
> So with that I thought that I need to modify the 'trandic' script, which I did. I copied it to a new name and modified the original 'if' line that would give a clean_run=1. Sadly, I'm horrible at regex but I've used a few online tools to verify the expression. I also added a PRINT line inside that scope so I would see if it went into it or not.

Hi.  What device type are you using for this device in your router.db
configuration file?  I am not familiar with the N3048, but it looks like
it is just a switch.  So, I would expect it to be device type 'dell' or
'smc'.  Could you try one of those?

> if (/[>#]\s?exit$/) {

> I've tried others more loose as well but nothing makes it go into that 'if' when I run it.
