#3 Thanks for keeping up the good fight, Fred!

IPs are from Taiwan, Switzerland, USA (Utah), and China respectively, per this IP locator...?

#4 One from Taiwan. one from Germany, one from Beaverton Or and one from mainland China.

Looks as if one is an owned server.

#7 Fred - on a Linux system you can change the default sshd port to something other than 22. It won't stop a determined hacker from attacking (after first port-scanning). But it'll keep the random script kiddies out.

#8 You can also firewall it in such way only a limitative list of networks/adresses may access the sshd port.

#9 Is there a way to set it up so that not all users with accounts can connect? They've been trying to log in using lists of first names. I want to allow only two users, three at the outside.

#12 In /etc/ssh/sshd_config

Add a line like:

AllowUsers userid1 userid2 userid3

Only these three users can connect via ssh

#13 Is there a way to set it up so that not all users with accounts can connect?

Users restricted to FTP should get /bin/nologin as shell.

You can also edit /etc/security/access.conf as a way to control who can login

Feel free to mail me as often as you like for technical questions.

#14 Fred: Edit sshd_config to Allow USers.

First man sshd_confiog for a full list.

My servers have that problem too, but it can be tempered by limiting the grace time from connect to login to something like 30 seconds and max 2 attempt. That way those dictionary attackss will go way down.

And since this is a remote machine you'll have to reboot the machine for the changes to take affect.

Serious execute man sshd_config for all the options. sshd is wonderful work of unix technology.
