"Received disconnect from IP_address:
2: too many failed userauth_requests"
After reducing MaxAuthRetries
to 3 from the default of 6 on Solaris 9's ssh server, I received this
error when trying to connect with an OpenSSH client.
OpenSSH_3.6.1p2, SSH protocols
1.5/2.0, OpenSSL 0x0090701f
By default, the OpenSSH client attempts authentication in the following
By running the ssh server in debug mode (/usr/lib/ssh/sshd -d), I was able to
see the problem. In my case, "hostbased" authentication failed, as did
"publickey" authentication. OpenSSH presented both my ssh protocol 2
RSA and DSA identities to the ssh server, resulting in two "publickey"
authentication failures. I already had 3 failures by the time I was
presented with the password prompt, so entering the correct password
resulted in an error.
Authorized uses only. All
activity may be monitored and reported.
Received disconnect from

There are several workarounds:
1. Use public-key authentication by adding the appropriate public key
to the authorized_keys file
on the remote host. If you have more than one identity (e.g. ssh
protocol 2 DSA and RSA keys), you may want to specify the appropriate
identity with ssh -i identity_file. Recommended.
2. If you have to use password authentication, run the ssh client with ssh -o PreferredAuthentications=password to
prevent hostbased, publickey, and keyboard-interactive authentication
3. Change MaxAuthRetries on
the ssh server to a larger value.
