If you can change the root password and removing the sudo privileges to switch user to root, even better. No access means no chance of errors by them again. Be careful with sudo rules though. Some commands sudh as vi, ftp and seemingly harmless more may allow you to escape to a shell prompt as a root privilege user. Work on the basis of allowing as little as possible for everything.


If you have to share access, do you have a line in your /etc/syslog.conf (or rsyslog.conf) for:-
Code:
*.debug       /my/system/log

If so, then there may be some clues in there, whatever it is defined to. The problem may come in working out what action caused the problem, when it happened and then tracing back. Perhaps you could include some tracing in your /etc/profile to record more useful information.



I hope that this helps,

dtc_install_centos

dtc_install_centos(8)					      System Manager's Manual					     dtc_install_centos(8)

NAME

       dtc_install_centos - bootstrap a CentOS install to use in a chroot or VM

SYNOPSIS

       dtc_install_centos <install root> <yum environment>

DESCRIPTION

       This  shell  script is part of the dtc-xen package, generally to be used by the dtc panel to install a new a Xen VPS server. This script is
       called by dtc_reinstall_os when the user chooses to install the CentOS operating system.

       How it works: it generates a temporary yum configuration in the yum environment directory, that directs yum to act inside the install  root
       instead	of  in	the base system; then it kindly requests yum to install the basesystem, centos-release and yum packages onto it.  Yum then
       uses the configuration to download the required (usually, security-updated) packages and then perform the RPM  installation  process  under
       the install root.

       It  requires  both  RPM	and  yum.  It does work under Debian (it was developed in Ubuntu first).  It should also work on RPM-based systems
       without destroying the system-wide RPM and yum configurations.

OPTION

       <install root>

       Target directory where CentOS will be deployed.	Must exist beforehand.

       <yum environment>

       Directory where yum will store the repository manifests and configuration.  Will be automatically created.  Cached RPMs and manifests  will
       be left, as usual, in a directory var/cache/yum inside the install root.

EXAMPLE

       dtc_install_centos /root/yum /xen/13

       This will setup the operating system in /xen/13, with the CentOS configuration folder in /root/yum.

BUGS

       It's limited to CentOS 5 at the moment.

       It must be run as root.

       Under  some  circumstances,  the installation process itself may kill processes running on the host machine.  The chroot yum does should be
       sufficient to avoid this, but we haven't been able, yet, to ascertain why this fails sometimes.
