Помогите, пожалуйста, вот с какой проблемой. Никак не получается настроить доступ root-у между узлами по ssh без пароля. ssh-keygen -t и т. д. прекрасно работает, но только для непривилегированных пользователей. Ключи для всех без исключения генерируются при входе в систему с помощью скрипта, лежащего в /etc/profile.d (из OSCAR 4.2):

#!/bin/sh
user=`whoami`
home=`getent passwd | egrep "^$user\:" | awk -F: '{print $6}' | tail -1`
cd $home

file=$home/.ssh/id_rsa
type=rsa
if [ ! -e $file ] ; then
echo generating ssh file $file ...
ssh-keygen -t $type -N '' -f $file
fi

id="`cat $home/.ssh/id_rsa.pub`"
file=$home/.ssh/authorized_keys
if ! grep "^$id\$" $file >/dev/null 2>&1 ; then
echo adding id to ssh file $file
echo $id >> $file
fi

chmod 600 $home/.ssh/authorized_keys*

Картина следующая: для root:
#ssh -v s-cl1-01
[cut]
debug1: Host 's-cl1-01' is known and matches the RSA host key.
debug1: Found key in /root/.ssh/known_hosts:2
debug1: ssh_rsa_verify: signature correct
debug1: SSH2_MSG_NEWKEYS sent
debug1: expecting SSH2_MSG_NEWKEYS
debug1: SSH2_MSG_NEWKEYS received
debug1: SSH2_MSG_SERVICE_REQUEST sent
debug1: SSH2_MSG_SERVICE_ACCEPT received

Для пользователя всё прекрасно:
$ ssh -v s-cl1-01
[cut]
debug1: Host 's-cl1-01' is known and matches the RSA host key.
