Configuring Terminal (MAC) for legacy iOS

[MichaelMcCoy]

Hello Team,

Over the weekend I ran into the issue with Legacy IOS devices (in my home environment) and using a MAC to try to attempt to SSH into the legacy device. Getting SHA1 errors, "Unable to negotiate with x.x.x.x port 22: no matching key exchange method found. Their offer: diffie-hellman-group1-sha1"

Has anyone ever dealt with this and may be able to help me get around it? I have researched it, and things that I am readying/trying just don't seem to work.

I saw this and was a bit confused.  Would I need to save the etc/ssh/ssh_config file after making the changes?  Do I just run a seperate terminal while I have the "#" removed?

I just figured out that cntrl + O will save it after I am done making the change.
