Enable SSH for root over certain network connection of a server...is it possible?
Hi - I have a SUSE Enterprise Linux Server V9 that I have an issue with. Policy says that root connectivity via ssh needs to be disabled. So, to do that, I made the following change in the sshd_config section:

Code:
# Authentication:

#LoginGraceTime 2m
#PermitRootLogin yes
PermitRootLogin no
#StrictModes yes
#MaxAuthTries 6

The issue is that a utility that the vendor uses uses root to connect via ssh across the two servers in our configuration to collect logging and reporting information. when I disable root login in sshd_config, it breaks their utility. I asked why they would have it run as root and not as some privledged account...but I have not received an answer yet. In our configuration, we have 3 networks (2 are private networks and 1 is connectivity to the corporate network.) My question, is it possible to disable root Login via ssh for some network segments but not others?

ssh-ldap-helper

SSH-LDAP-HELPER(8)					    BSD System Manager's Manual 					SSH-LDAP-HELPER(8)

NAME

     ssh-ldap-helper -- sshd helper program for ldap support

SYNOPSIS

     ssh-ldap-helper [-devw] [-f file] [-s user]

DESCRIPTION

     ssh-ldap-helper is used by sshd(1) to access keys provided by an LDAP.  ssh-ldap-helper is disabled by default and can only be enabled in the
     sshd configuration file /etc/ssh/sshd_config by setting AuthorizedKeysCommand to ``/usr/libexec/openssh/ssh-ldap-wrapper''.

     ssh-ldap-helper is not intended to be invoked by the user, but from sshd(8) via ssh-ldap-wrapper.

     The options are as follows:

     -d      Set the debug mode; ssh-ldap-helper prints all logs to stderr instead of syslog.

     -e      Implies -w; ssh-ldap-helper halts if it encounters an unknown item in the ldap.conf file.

     -f      ssh-ldap-helper uses this file as the ldap configuration file instead of /etc/ssh/ldap.conf (default).

     -s      ssh-ldap-helper prints out the user's keys to stdout and exits.

     -v      Implies -d; increases verbosity.

     -w      ssh-ldap-helper writes warnings about unknown items in the ldap.conf configuration file.

SEE ALSO

     sshd(8), sshd_config(5), ssh-ldap.conf(5),

HISTORY

     ssh-ldap-helper first appeared in OpenSSH 5.5 + PKA-LDAP .
