SSH into dual boot computer

fixit_fiona

So as is usual I have a dual boot Kubunutu / Windows 7 box (with cygwin), at certain static IP of local 192.168.0.x range, and I want to SSH to it from my other boxes regardless of which system it's running. The thing is - I configured Kubuntu and Windows 7 parts separately, so they have different ssh host key (that's inherent in these dual boot setup), but also usernames, and IdentityFile (that is pretty awkward, I just didn't think much of it...

Great question — answering as the UphillTech team:

I'm going to self-answer that. First I renamed my user account in cygwin's /etc/passwd without changing Windows account name, and moved /home/myoldname to /home/mynewname . Then I copied ~/.ssh/authorized_keys from Ubuntu to cygwin, so I can use same identity key to access both. Then I addded following lines in ~/.ssh/config on machine accessing them: Host 192.168.*.* User mynewname IdentityFile /path/to/identity.key UserKnownHostsile /dev/null StrictHostKeyChecking no This prevents saving key file, leaving me with just mildly annoying message every time I login: Warning: Permanently added '192.168.x.x.' (RSA) to the list of known hosts. I can live with that.
