Hi Admins,

I am not able to login AIX 5.3 server using ssh

recieving below error

 # ssh 10,.10.101.10
ksh: ssh: 0403-006 Execute permission denied.

below is sshd_config file

I just restarted the sshd subsystem after some changed the

.But i revoked the same .

Maybe because of this in your command line (emphasis added):

# ssh 10,.10.101.10

Hi pludi,

Thanks for the response. That was just an type error.

Actually i can login to this said server from other server and from putty.
But when i execute ssh from this server getting error.

Below are the permissions of ssh file

-rw-r--r--    1 root     system         2902 Aug 09 2010  sshd_config
-r-xr-xr-x    1 root     system       738444 May 14 2006  /usr/sbin/sshd

So where is your sshd_config file shown above from? The following should have the # removed

#PermitRootLogin yes

Or is it your standard user ID which cannot ssh to the server? I have assumed that you are connecting as root.

Your "Execute permission denied" is coming from your "ssh" command, not your "sshd". What does your ssh file look like?

hostname:/:$ ls -l `which ssh`
-r-xr-xr-x    1 root     system      1661456 Aug 03 2011  /usr/bin/ssh
hostname:/:$

If what you have above is the sshd_config file on the client machine, that is the wrong config file. That one is for the ssh server. In this scenario, that box would be the client and the client configuration file is /etc/ssh/ssh_config (no "d").
