RHCT skills

Troubleshooting and System Maintenance

RHCTs should be able to:

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

Installation and Configuration

RHCTs must be able to:

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, quotas, and File Access Control Lists configure filesystem permissions for collaboration install and update packages using rpm properly update the kernel package configure the system to update/install packages from remote repositories using yum or pup 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 scripting to automate system maintenance tasks configure NTP for time synchronization with a higher-stratum server

RHCE skills

Troubleshooting and System Maintenance

RHCEs must demonstrate the RHCT skills listed above, and should be able to:

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 diagnose and correct networking services problems where SELinux contexts are interfering with proper operation.

Installation and Configuration

RHCEs must demonstrate the RHCT-level skills listed above, and they must be capable of configuring the following network services:

HTTP/HTTPS SMB NFS FTP Web proxy SMTP IMAP, IMAPS, and POP3 SSH DNS (caching name server, slave name server) NTP

For each of these services, RHCEs must be able to:

install the packages needed to provide the service configure SELinux to support 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 iptables to implement packet filtering and/or NAT use PAM to implement user-level restrictions

Based on this RHCE guide we have created step by step guide of RHCE exam. By our RHCE guide you can get your RHCE certificates. We have managed various practical example and suggest you to go through all these.
