RHCE Requirements


Bei RedHat gibt es zwei Listen, und man muss die Inhalte beider genau kennen, wer lesen kann ist klar im Vorteil – im folgenden beide zusammengefasst.

use standard command line tools (e.g., ls, cp, mv, rm, tail, cat, etc.) to create, remove, view, and investigate files and directories
use grep, sed, and awk to process text streams and files
use a terminal-based text editor, such as vi/vim, to modify text files
use input/output redirection
understand basic principles of TCP/IP networking, including IP addresses, netmasks, and gateways
use su to switch user accounts
use passwd to set passwords
use tar, gzip, and bzip2v
configure an email client on Red Hat Enterprise Linux
use mozilla and/or lynx to access HTTP/HTTPS URLs
use lftp to access FTP URLs
boot systems into different run levels for troubleshooting and system maintenance
diagnose and correct misconfigured networking
diagnose and correct hostname resolution problems
configure the X Window System and a desktop environment
add new partitions, filesystems, and swap to existing systems
use standard command-line tools to analyze problems and configure system
perform network OS installation
implement a custom partitioning scheme
configure printing
configure the scheduling of tasks using cron and at
attach system to a network directory service, such as NIS or LDAP
configure autofs
add and manage users, groups, and quotas
configure filesystem permissions for collaboration
install and update RPMs
properly update the kernel RPM
modify the system bootloader
implement software RAID at install-time and run-time
use /proc/sys and sysctl to modify and set kernel run-time parameters
use the rescue environment provided by first installation CD
diagnose and correct boot failures arising from bootloader, module, and filesystem errors
diagnose and correct problems with network services (see Installation and Configuration below for a list of these services)
add, remove, and resize logical volumes

RHCEs must demonstrate the RHCT-level skills listed above, and they must be capable of configuring the following network services:
Web proxy
DNS (caching name server, slave name server)
For each of these services, RHCEs must be able to:
install the packages needed to provide the service
configure the service to start when the system is booted
configure the service for basic operation
Configure host-based and user-based security for the service

RHCEs must also be able to:
configure hands-free installation using Kickstart
implement logical volumes at install-time
use PAM to implement user-level restrictions
