<![CDATA[DCI over SSH Fails on Mikrotik device only]]>I have some mikrotik wireless devices that I need to monitor signal strength and SNR  and because of the odd way the Mikrotik MIBS are formatted and having to know the connected clients mac in order to retrieve that info from the registration table via snmp i decided to do it over ssh but it always fails on the Mikrotik device.  I have tested the commands from the server using the native ssh client and everything works.  I have also setup a laptop and simple dci with uname -a command and that is successful it just does not like the Miktotik response for some reason.  Below are the responses any suggestions are much appreciated.

 Successful Laptop Response:

Good Idea though

I think those are special chars in some cases. This is just a hot take as I didn't check the docs or anything, but thought it was worth a try in case you haven't already thought of it.
