Weird commands on Cisco ASA
Hello,

I have a firewall that has not been updated by rancid for a few days.

Upon investigation I did some testing from the server found this -

Looks like it is adding the command 'rancid' after it logs in.

This is my only device that does it, among the 50+ that rancid is polling.

[rancid@netwatch bin]$ ./clogin <hostname removed>
<hostname removed>
spawn ssh -c aes256-ctr -x -l rancid <hostname removed>
rancid@<hostname removed>'s password:
