SSH How to ignore checking IdentityFile?

I have setup a config file located at "~/.ssh/config" which contains some IdentityFile lines to point to the key files that I use for some of my servers.

e.g. IdentityFile ~/Data/Keys/KeyFile.pem

This works fine when I want to connect to my servers on ec2 which require a key file for authentication.

When I want to connect to a server that does not use a key file and requires a password ssh tries to use my key files in ~/.ssh/config and the connection fails with:

Received disconnect from host.ip: 2: Too many authentication failures for root

Is there a ssh command argument that I can use to connect to this server so that ssh does not try to use my identity files?

Solution 1:

You should be able to limit the use of the IdentityFile lines to your EC2 host with the host statement:

Host YourEC2host.com 
    IdentityFile ~/Data/Keys/KeyFile.pem

For more information, see the section about the host section in the ssh_config man page.
