I could be wrong (I assumed the server config). However, even in the
client case, could the ssh client be connecting to either a protocol 1 sshd
or a protcol 2 sshd. If you list "Protocol 1", attempts to contact a
protocol 2 only sshd would fail; if you list "Protocol 2", attempts to
contact a protocol 1 only sshd would fail; if you list "Protocol 1,2",
attempts to contact either a protocol 1 or protocol 2 only server would
succeed. Note that these are all assumptions and I should really check the
code for confirmation but the man page seems to agree:
Protocol
Specifies the protocol versions ssh should support in order of
preference. The possible values are ``1'' and ``2''. Multiple
versions must be comma-separated. The default is ``1,2''. This
means that ssh tries version 1 and falls back to version 2 if
version 1 is not available.
