I have the following ssh config file:
Host git.github.com
User git
IdentityFile ~/.ssh/id_rsa
Host git.assembla.com
User git
IdentityFile ~/.ssh/id_rsa_assembla
Host XXX.XXX.XXXX.group
IdentityFile ~/.ssh/id_rsa_gerrit
User xxxx
But when I try and log in, I get:
Unable to negotiate with XX.XXX.XXX.XXX port XXXX: no matching key exchange method found. Their offer: diffie-hellman-group1-sha1 fatal: Could not read from remote repository.
