Hello, ok been digging deeper nad now believe that this is down to SSH2 public keys issue which is not working on server.

Code:
In /var/log/messages when the cpanel user tries to SSH as root, the following errors occur:
Feb 18 14:33:17 cp sshd[43030]: error: ssh_msg_send: write
Feb 18 14:33:29 cp sshd[43056]: error: ssh_msg_send: write

I can ssh into box but the web CP must communicate over SSH2 public keys which is iy is failing to do?


Also what should permissions be for:

Code:
 /root/.ssh and /root/.ssh/authorized_keys2
here is my current sshd_config

Code:
cp# cat /etc/ssh/sshd_config
#       $OpenBSD: sshd_config,v 1.74 2006/07/19 13:07:10 dtucker Exp $
#       $FreeBSD: src/crypto/openssh/sshd_config,v 1.42.2.4 2006/11/11 00:51:28 des Exp $

# This is the sshd server system-wide configuration file.  See
# sshd_config(5) for more information.

# This sshd was compiled with PATH=/usr/bin:/bin:/usr/sbin:/sbin

# The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
# possible, but leave them commented.  Uncommented options change a
# default value.

# Note that some of FreeBSD's defaults differ from OpenBSD's, and
# FreeBSD has a few additional options.
