[rancid] What's difference between "show running-config" and "show config" parsing?

[Sam Munzani]

Team,

I have a situation where the end user doesn't permit enable access to 
the rancid user. On return, they allow all "show" commands by doing some 
"privilege exec" commands on the router. That means, I can't run "show 
run" command if I am logged in as rancid user. However I can do "show 
config" command which reads the startup configuration file from the nvram.

I compared end of both configuration and they are identical.
---------- show run output last 4 lines -----------
ntp clock-period 17179646
ntp server x.x.x.x  prefer
ntp server x.x.x.y
end
--------------------------------------------------
---------- show config output last 4 lines --------
ntp clock-period 17179646
ntp server x.x.x.x  prefer
ntp server x.x.x.y
end
--------------------------------------------------

Literally no difference at all.

However following doesn't work and throws "End of run not found" error 
in the log.

1. Configure .cloginrc with following setup. and modify bin/rancid 
script to run "show config" command instead of show run.
add user *       {rancid}
add password * {rancidpass}
add method * ssh
add cyphertype * {3des}
add autoenable * 1   # I set autoenable to 1 because rancid account 
login puts to "#" prompt since its a priv-2 account

Technically it should work fine since both commands produces same output 
and end of file but it doesn't work for some reason. Any advise on how 
to troubleshoot this one?

Thanks,
Sam
