Operating Systems Linux SuSE Auditors want more security with root to root access via ssh keys Post 302831679 by dvbell on Thursday 11th of July 2013 01:17:31 PM

Wrench Auditors want more security with root to root access via ssh keys

I access over 100 SUSE SLES servers as root from my admin server, via ssh sessions using ssh keys, so I don't have to enter a password. My SUSE Admin server is setup in the following manner:

1) Remote root access is turned off in the sshd_config file.

2) I am the only user of this admin server.

3) My user account is not allowed sudo access, so I must use su and know the root password.

4) ssh keys are setup to the remote servers root accounts.

What I need, in order to satisfy the auditors is a password being required when I use ssh. However, the ssh passphrase will not work since it will require a login password at each server. I need something that will require a password once, so I can do a script to hit all servers without having to enter a password at each server the script hits.

Any ideas? Thanks in advance.

SSH-KEYSIGN(8)						    BSD System Manager's Manual 					    SSH-KEYSIGN(8)

NAME
ssh-keysign -- ssh helper program for hostbased authentication SYNOPSIS
ssh-keysign DESCRIPTION
ssh-keysign is used by ssh(1) to access the local host keys and generate the digital signature required during hostbased authentication with SSH protocol version 2. ssh-keysign is disabled by default and can only be enabled in the the global client configuration file /etc/ssh/ssh_config by setting HostbasedAuthentication to ``yes''. ssh-keysign is not intended to be invoked by the user, but from ssh(1). See ssh(1) and sshd(8) for more information about hostbased authen- tication. FILES
/etc/ssh/ssh_config Controls whether ssh-keysign is enabled. /etc/ssh/ssh_host_dsa_key, /etc/ssh/ssh_host_rsa_key These files contain the private parts of the host keys used to generate the digital signature. They should be owned by root, read- able only by root, and not accessible to others. Since they are readable only by root, ssh-keysign must be set-uid root if hostbased authentication is used. SEE ALSO
ssh(1), ssh-keygen(1), ssh_config(5), sshd(8) AUTHORS
