As someone else already mentioned, you can't do this with OpenSSH. You can, however, do it with some sort of firewall software. They posted instructions for using Linux's kernel-based firewall software; if you're not using Linux, there should be a similar thing available for your OS (though if it's a commercial OS, you will likely need commercial software). > In your answer, you mention settings in sshd_config.

No; or more exactly, only to the extent that the SSH server exerts control over connecting clients (but generally no). -- Derek D. Martin http://www.pizzashack.org/ GPG Key ID: 0x81CFE75D
