From: Ilya Leoshkevich <iii@linux.ibm.com>

When one has a lot of keys in ~/.ssh directory, the ssh command will
try all of them before the one specified on the command line, and this
may cause the remote ssh server to reject the connection due to too
many failed authentication attempts.

Fix by adding -o IdentitiesOnly=yes, which makes the ssh client
consider only the keys specified on the command line.
