Hi all,

Does anybody know the syntax for cloginrc and router.db for edgerouters?

I've tried various permutations and either:
- it won't log in because there isn't an enable password
- if I set autoenable to 1, it will log in but fail to back up:

$ clogin -t edgerouter MYDEVICE
MYDEVICE
spawn ssh -x -l ubnt MYDEVICE

$ clogin -t edgerouter MYDEVICE

ulogin

That's only part of it, though. I still need the right .cloginrc commands.
If I use ulogin, then:

$ ulogin MYDEVICE
MYDEVICE
spawn ssh -x -l ubnt MYDEVICE

ubnt
***@MYDEVICE:~$ ubnt
-vbash: ubnt: command not found
***@MYDEVICE:~$

Where is that extra "ubnt" coming from?

I expect the "Last login:" message is confusing ulogin and that's why it
sends the username again.

I'm dependent on the debian releases, but I've added the changes you've
made to our running version of ulogin, and it works fine now. Thanks for
your help.
