I am a very new linux user. Some background: I am systems programmer on a IBM Mainframe. Just recently I installed Linux (Suse 8) under Z/vm on the mainframe. I am able to clone Linux instances at will. I did this for myself as a sand box. The question I have and remember I know nothing about linux (a little but not much), is how do I get the SSHD deamon to run. I want to be able to run ssh-keyscan and so far I get nothing in return. I have installed SSH (IBM Imported tools) on the mainframe and it works as advertised. All I am trying to do is SFTP a file for the linux box to the mainframe but continueally get permission denied. Can anyone help?

Hi TimeBandit,

SSHD should be in the /etc/init.d folder.

To start the ssh daemon you should type

/etc/init.d/sshd start

sshd is a script that can accept start, restart or stop as command line options.

Hope that helps.

That worked great. SSH-keyscan works great. Now I have the host pub key in my known_hosts file. I still get permission denied when I try to SFTP. Any ideas. Here is the debug.

Thanks for the help

Have you configured your sshd_config file?

If not look in /etc/ssh for the file sshd_config.
There is to much in there for me to go through here but
you need to uncomment out the lines you want to
use, such as RSA authentication and pubkey auth.
It all depends on how you want to be able to access
the ssh daemon.

Also check out your authorized_keys file. If you just want
to access with keys then your key needs to be in the
authorized_keys file.

Hope that helps.

Zack

I have looked at the sshd_config file on both platforms and I have left them pretty much at the default value. The authorized_keys file on the Linux box only has one key in it, the mainframes dsa key.
