[rancid] microtik problems

[Michael W. Lucas]

Hi,

I'm trying to use the MicroTik scripts from
http://falz.net/tech/rancid-mikrotik, but have a couple of issues.

1) Setting a SSH port doesn't work. If I use this config:

add password core-5 password
add user core-5 username
add method core-5 ssh
add method core-5 {ssh:-2222}
add autoenable core-5 {1}

I get this:

%clogin core-5
core-5
spawn ssh -c 3des -x -l admin core-5
ssh: connect to host core-5.lodden.com port 22: Connection refused

Error: Connection Refused (ssh): core-5
%

I can work around this with:

add sshcmd core-5 {ssh -p 2222}

which gives me a login prompt, but the prompt is "nonresponsive."
Anything I type doesn't go into the router; it appears on the Unix
command line, after the connection times out.

Any suggestions, folks?

Thanks,

Michael,

I wonder if the issue has something to do with the Mikrotik doing a
color terminal by default? If you look at the code it looks like it's
supposed to append '+ct' to your username when you log in which
disables color (c) and terminal autodetection (t) per changelog:

I did a clogin test using ssh and I had the same issue. Doing it over
telnet does let me interact with the device. However, rancid-run -r
<mikrotik> does work properly.

Chris,

Thanks for the hint (and the script). I wound up with the following
working configuration:

add password core-5 YourPasswordHere
add user core-5 username+ct
add method core-5 ssh
add sshcmd core-5 {/usr/local/scripts/microtiklogin.sh}
add noenable core-5 {1}

sshcmd apparently doesn't handle spaces well, so I had to use an
external script. The sshcmd script is just:

#!/bin/sh
exec ssh -p 2222 $@

I guess that the SSH username part of mtlogin doesn't add +ct
correctly.

This should fix that and will be included in the next release along
with the mikrotik module from Chris Boot.
