Not necessarily the best way, but it works for me.

Login as that user and run: ssh-keygen -t rsa I don't have many users so I disable ChallengeResponse authentication and require users to submit keys. To do that, edit /etc/ssh/sshd_config and set: ChallengeResponse no I also set: Protocol 2 > 2. setup users on FreeBSD remote box to ssh to sshd server. Have them run the same ssh-keygen -t rsa Tell them to send you ~/.ssh/id_rsa.pub Concatenate that to the ~/.ssh/authorized_keys2 files in their home directory on your server. Make sure the key ends up on a new line in authorized_keys2. If there wasn't a newline at the end of the file previously, it will end up concatenating it to the end of whatever keys are already there. If that happens, just go in with a text editor and break the line. The user should then be able to ssh into your box. > 3. setup users on windows/xp remote box to ssh to sshd server. Install Putty http://www.chiark.greenend.org.uk/~sgtatham/putty/ Run puttygen and generate an SSH2 RSA key (select this at the bottom of the dialog box). Tell them to save the public and private keys, and then to copy the contents of the Public key for pasting.. field at the top of the screen, paste it into a file in notepad, and email it to you. Concatenate that to the end of their ~/.ssh/authorized_keys2 file as you did for your freebsd users. If they're going to be logging in often, tell them to run pageant to cache the private key. Then they can run putty and connect to your server. Again, you might not want to do it this way if you don't want to mess around with having users send you keys, but it's a lot more secure. Pretty soon you'll be be getting a 100 or more hits a day from crackers trying to log into your system. They'll never get anywhere if you're using key based authentication. -- Ken Stevenson Allen-Myland Inc. ******************************************************************* -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Ken Stevenson Sent: Wednesday, February 08, 2006 6:02 PM To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] ORG Subject: Re: sshd / ssh setup Ken Thanks that helps a lot. Only thing missing is what is ssh login syntax to login from the remote FreeBSD pc? Can I also remotely login as root on sshd server system? I guess the setup instructions are with the putty pgm for ssh access from windows/xp _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
