RHEL 5.1 has been released. Redhat announced the availability of Red Hat Enterprise Linux 5.1, with integrated virtualization. This release provides the most compelling platform for customers and software developers ever, with its industry-leading virtualization capabilities complementing Red Hat’s newly announced Linux Automation strategy. It offers the industryâ€™s broadest deployment ecosystem, covering standalone systems, virtualized systems, appliances and web-scale “cloud” computing environments.
Besides supporting Linux virtual machines, RHEL 5.1 will also support Windows XP, Windows 2000, Windows Server 2003 and the forthcoming Windows 2008, Crenshaw said. RHEL 5.1 uses Xen for its virtualization.
How do I upgrade to RHEL 5.1?
Login as the root user and simply type the command to fetch all updates via RHN:
# yum update
Depend upon your network condition and software configuration it may take anywhere between 5-20 minutes. Once completed, just reboot the server:
Verify that everything is working fine:
# netstat -tulpn
# netstat -nat
# tail -f /var/log/messages
# egrep -i 'error|warn' /var/log/messages
# egrep -i 'error|warn' /path/to/apps/log
Community driven enterprise CentOS Linux users should expect update soon too. You can apply above commends to upgrade your CentOS box.
If you have recently updated your Red Hat Enterprise Linux Server release 5.1 (Tikanga) / CentOS 5.1, dovecot imap server might give out the following error:
Nov 5 13:21:13 p5ora1 dovecot: imap-login: imap-login: error while loading shared libraries: libsepol.so.1: failed to map segment from shared object: Cannot allocate memory
Nov 5 13:21:13 p5ora1 dovecot: pop3-login: pop3-login: error while loading shared libraries: libsepol.so.1: failed to map segment from shared object: Cannot allocate memory
This error is not related to shared libraries. You need to set maximum process size in megabytes. If you don’t use login_process_per_connection you might need to grow this. Just open /etc/dovecot.conf file
# vi /etc/dovecot.conf
Find line read as follows:
Uncomment and set it to 64:
login_process_size = 64
Save and close the file. Restart dovecot imap server:
# /etc/init.d/dovecot restart
The Dovecot package on x86_64 (64 bit system) kernels requires the parameter “login_process_size = 64” to be added to /etc/dovecot.conf after an upgrade to RHEL / CentOS 5.1.
Currently Dell only offers Red Hat Enterprise Linux (RHEL) and Suse Novell on Dell Server. Canonical, the company that supports Ubuntu Linux, is trying to work out a deal with hardware vendors such as Dell to make Ubuntu available preinstalled on servers.
Ubuntu Desktop from Dell was the first preinstalled mainstream distro for end users. It’s been hard to tell how popular the Ubuntu desktop has been for Dell, which started selling the OS in May on two desktop PCs and the Inspiron E1505n notebook. Asked how well those PCs have sold, Canonical referred the questions to Dell. A Dell spokeswoman said the figures are confidential. I’m quite sure there will be a good demand for server product too.

VMware virtualization software is an excllent choice for x86-compatible computers. They have both commercial and free version. I received few email regarding VMWARE on 64 bit Linux. Installing VMWARE server on CentOS 5 or Red hat enterprise Linux 64 bit version is a tricky business. In this small howto I will explain vmware installation on 64 bit Linux server without facing any dependencies problem.
Following instructions are tested on both RHEL 5 and CentOS 5 running 64 bit Intel / AMD hardware and software. My kernel:
$ uname -mrs
Linux 2.6.18-8.1.6.el5 x86_64
My RHEL 5 release (same kernel for CentOS):
$ cat /etc/redhat-release
Red Hat Enterprise Linux Server release 5 (Tikanga)
Make sure you have following software installed:
- Full gcc compiler and development environment
- Kernel headers and devel packages for current kernel (i.e. kernel-headers and kernel-devel)
