[rancid] ssh problems

[Wayne Eisenberg]

The ASA? The key there existed before my involvement, so I have no idea where it was generated. But I thought this was a problem with the local key of the rancid host, which was generated on it.

You didn’t by chance generate this key your using on a windows device and then SCP it to your asa did you?  All the white space errors are jumping out at me making me think there’s a problem in the CR / LF handling but that’s an absolute pure guess so please add as many grains of salt as you feel is warranted.:)

Hi all,

I was setting up a new ASA 5545 to be part of our happy family, and it would not let rancid/ssh login to it, although putty has no problem. The output I get is:

The relevant part of the firewall config:
ssh scopy enable
ssh y.y.y.y z.z.z.z outside
ssh 0.0.0.0 0.0.0.0 inside
ssh timeout 30
ssh key-exchange group dh-group1-sha1

I suspect the key-exchange group line is the issue, but dang if I can figure out how to resolve it. I do not have any problems with using ssh on any other device at all. So yes, I have an id_rsa file that seems to be just fine since I connect to all the other devices.

The /etc/ssh/ssh_config file is only comments, no commands in there. If I try to add a line for KexAlgorithms, ssh gives me an error, ‘bad configuration option’.

ssh –V => OpenSSH_5.1p1, OpenSSL 0.9.8i 15 Sep 2008
ssh –Q is not a valid option


Any ideas?

Thanks,
Wayne
