Hi,

I read through this thread ending with no solution
http://www.shrubbery.net/pipermail/rancid-discuss/2013-November/007279.html

Things I have tried:

Version rancid-3.1-4.el6.x86_64

0.
add to ~rancid/.cloginrc the supermicro-switch settings

add autoenable supermicro-switch 1
add user supermicro-switch username
add password supermicro-switch password password
add method supermicro-switch ssh

1.
clogin shows errors out-of-the-box, this is expected

rancid $ clogin -c"show version" supermicro-switch
supermicro-switch
spawn ssh -c 3des -x -l username supermicro-switch
***@supermicro-switch's password:

Supermicro Switch

supermicro-switch#
supermicro-switch# terminal length 0
% Invalid Command
supermicro-switch# terminal width 132
% Invalid Command
supermicro-switch# show version
Switch ID Hardware Version Firmware Version OS
Version
0 XXX-XXXX Rev. X (XX-XX) X.X.X-X X.X.X
supermicro-switch#exit

2.
copy clogin to smlogin

root # cp /usr/libexec/rancid/clogin /usr/libexec/rancid/smlogin

and replace the offending
send "terminal length 0\r" and send "terminal width 132\r" with with send
"\r"

After that this returns without errors:

rancid $ smlogin -c"show version" supermicro-switch

3.
rancid $ rancid -d supermicro-switch
loadtype(): device_type is empty
Couldn't load device type spec for

So I add to /etc/rancid/rancid.types.base:

supermicro;script;rancid -t supermicro
supermicro;login;smlogin
supermicro;inloop;supermicro::inloop
supermicro;command;supermicro::ShowVersion;show version
supermicro;command;supermicro::WriteTerm;show running-config

and then:

rancid $ rancid -d -t supermicro supermicro-switch
loadtype: device type supermicro
loadtype: found device type supermicro in /etc/rancid/rancid.types.base
executing smlogin -t 90 -c"show version;show running-config"
supermicro-switch
supermicro-switch: missed cmd(s): all commands
supermicro-switch: End of run not found
supermicro-switch: End of run not found

but as we know executing directly on the command line works: smlogin -t 90
-c"show version;show running-config" supermicro-switch

To further debug I create `cp /usr/libexec/rancid/rancid
/usr/libexec/rancid/smrancid` and point to it with
supermicro;script;smrancid -t supermicro
but my guess is wrong: some other script than /usr/libexec/rancid/smrancid
is executed during `rancid -d -t supermicro supermicro-switch`

How to debug this further?

Regards,

Marcin

does supermicro actually make the switch, or is it an OEM for which a script
may already exist.

i'd start with rancid 3.5.1.

How to debug this further?

i'd start with rancid 3.5.1.

I'm at the latest version now.

$ rancid -V
rancid 3.5.1

$ cat ~/.cloginrc
add autoenable supermicro-switch 1
add user supermicro-switch username
add password supermicro-switch password password
add method supermicro-switch ssh

Created smlogin based on blogin so `smlogin -c"show version"
supermicro-switch` runs fine:

$ diff usr/libexec/rancid/blogin usr/libexec/rancid/smlogin
501c501
< send "more off\r"
---

Post by Marcin Dulak
send "no cli pagination\r"

Now, most of the posts suggest that the reason for getting "End of run not
found" is that rancid does not recognize
when the session to the switch is terminated. On Supermicro that seems to
be "supermicro-switch#exit".

I'm trying to find out the workflow of rancid in order to make the
adjustments:

$ grep '#exit\$' usr/share/perl5/vendor_perl/rancid/*
usr/share/perl5/vendor_perl/rancid/edgemax.pm: if (/\#exit$/) {
usr/share/perl5/vendor_perl/rancid/foundry.pm: if (/\#exit$/) {

$ grep '#exit\$' usr/libexec/rancid/*
usr/libexec/rancid/rrancid: if (/\#exit$/) {

First question: what is the purpose of usr/libexec/rancid/rrancid compared
to the perl modules under usr/share/perl5/vendor_perl/rancid?

Second question - I'm doing:

$ cat etc/rancid/rancid.types.conf
supermicro;script;rrancid
supermicro;login;smlogin
supermicro;inloop;edgemax::inloop
supermicro;command;edgemax::ShowVersion;show version

but I can see that there seem to be no effect due to what I write for some
of these options, e.g. I can do without errors:
supermicro;script;dummy
supermicro;login;smlogin
supermicro;inloop;dummy::inloop

I would imagine something like that would be caught by rancid configuration
parser as incorrect and prevent the run?

Adding debug prints to the check for completness in
usr/libexec/rancid/rancid (also suggested in some posts) is not helpful:
printf(STDERR "$host: missed cmd(s): all commands\n");
printf(STDERR "$host: $clean_run\n");
printf(STDERR "$host: $found_end\n");

$ rancid -d -t supermicro supermicro-switch
loadtype: device type supermicro
loadtype: found device type supermicro in ./etc/rancid/rancid.types.conf
executing smlogin -t 90 -c"show version" supermicro-switch
supermicro-switch: missed cmd(s): all commands
supermicro-switch: 0
supermicro-switch: 0
supermicro-switch: End of run not found

rancid is function used by some (eventually all) of the rancid modules.
rrancid is the redback module.

how would it know until it tries to import the module? I did add recently
for 3.6:

rancid.pm: check for existence of functions for given device type after
loading the modules for the type. return failure if any are missing.

naively I do:
cp usr/share/perl5/vendor_perl/rancid/edgemax.pm
usr/share/perl5/vendor_perl/rancid/supermicro.pm
change "package supermicro;" on the top and add a print STDERR ("I'm
here"); to ShowVersion,
but "I'm here" does no appear in the output of:
$ rancid -d -t supermicro supermicro-switch

This goes back to my question: what gets executed when I replace
"supermicro::" with "dummy::" in

$ cat ./etc/rancid/rancid.types.conf

you havent a module line in the device config below, so the module is not

thanks, this was missing. It was also important to specify the module to be
used with "supermicro;script;rancid -t supermicro".
Based on rancid-3.5.1, I managed to get the basic information out of the
switch with the following changes:

$ cat etc/rancid/rancid.types.conf
supermicro;script;rancid -t supermicro
supermicro;login;smlogin
supermicro;inloop;supermicro::inloop
supermicro;module;supermicro
supermicro;command;supermicro::ShowVersion;show version
supermicro;command;supermicro::WriteTerm;show running-config

do you/anyone have one of these that I can access remotely?
