sshd says that "Host *" is a bad configuration option.

I thought I had configured SSH, but it says that "Host *" is a bad configuration option. I've got a book that says "Host *" is ok, and I can't get it to work with "host *" or "Host *.*.*.*". What's wrong?

I haven't heard of an sshd option "Hosts". If that's supposed to restrict the hosts which are allowed to connect (or your "*" meaning all of them), there is the entry "ListenAddress" (defaults to, meaning no restriction). In addition, you should get a sshd which honors the /etc/hosts.allow/deny entries. Finally, that restricting business is nice to keep the inherently good guys out but better done with a firewall which usually also helps against the bad guys. There were numerous sshd exploits which require, obvioulsy, that your connection reaches sshd in the first place, while a firewall prevents already that.

If you are still confused, post a few version numbers, sshd config files, and you will be helped.

I understand what you're saying. I also understand I need to get a new SSH book.
