Red Hat Enterprise Linux 7 Beta Arrives


Red Hat yesterday announced the beta availability of its next-generation Red Hat Enterprise Linux (RHEL) 7 operating system platform. The new beta marks the first major public milestone release of RHEL 7, which is the successor to the RHEL 6 platform that first debuted in 2010 and was most recently updated with the 6.5 release in November of this year.

"With today's announcement, we are inviting Red Hat customers, partners, and members of the public to provide feedback on what we believe is our most ambitious release to date. Red Hat Enterprise Linux 7 is designed to provide the underpinning for future application architectures while and providing the flexibility, scalability, and performance needed to deploy across bare metal, virtual machines, and cloud infrastructure", says Red Hat.

The company further adds, "based on Fedora 19 and the upstream Linux 3.10 kernel, Red Hat Enterprise Linux 7 will provide users with powerful new capabilities that streamline and automate installation and deployment, simplify management, and enhance ease-of-use, all while delivering the stability that enterprises have come to expect from Red Hat".

One of the big changes coming in RHEL 7 is the move from Ext4 to XFS as the default file system. Ext4 and its predecessor Ext3 have long been the default file systems in Red Hat's Linux distributions. However, Pacheco said, across all industries, Red Hat's customers are dealing with a data explosion—which shouldn't surprise anyone involved in the technology industry given the buzz around big data. "This enormous data growth requires a scalable, performance file system, which is provided by XFS— hence the move to it as the default file system," company said. XFS can support systems of up to 500TB in size; in contrast, Ext4 scales to a maximum stand-alone file system of 50TB.

CentOS / Redhat : Configure CentOS as a Software Router with two interfaces

Linux can be easily configured to share an internet connection using iptables. All you need to have is, two network interface cards as follows: a) Your internal (LAN) network connected via eth0 with static ip address 192.168.0.1 b) Your external WAN) network is connected via eth1 with static ip address 10.10.10.1  ( public IP provided by ISP ) Please note that interface eth1 may have public IP address or IP assigned by ISP. eth1 may be connected to a dedicated DSL / ADSL / WAN / Cable router: Step # 1: Enable Packet Forwarding Login as the root user. Open /etc/sysctl.conf file # vi /etc/sysctl.conf Add the following line to enable packet forwarding for IPv4: net.ipv4.conf.default.forwarding=1 Save and close the file. Restart networking: # service network restart Step # 2: Enable IP masquerading In Linux networking, Network Address Translation (NAT) or Network Masquerading (IP Masquerading) is a technique of transceivin

Virtual Box and Alt/Tab Keys

I use virtual box for all my testing activities. It comes too often that I have a virtual box VM window open & I want to switch to my host machine to see some stuff like tutorials etc.. If you press the alt+tab combination it just works inside the VM & doesn't switches to host machine. In these scenarios you can press the host key once ( not hold it ) & then whatever you press goes to host machine. So in general where host key is the default Right Ctrl, just press Right Ctrl once & now press the alt+tab & it will switch you out to host machine. This is really helpful when you have the VM windows open or you're working on seamless mode. Hope it help others too.

Set date and time in Linux

There are few ways to set the date and time on Linux command line. In order to do this, you must login as root and execute the following methods as follow: For you to remember the syntax, issue the command “date” first [root@linuxtechtips ~]# date Mon Aug 20 18:30:29 SGT 2012 Let say you want to change it to Sept 6, 2012, 3pm, just follow the pattern above [root@linuxtechtips ~]# date 090615002012 Thu Sep  6 15:00:00 SGT 2012 where as: 09 = month (September) 06 = day 15 = hour 00 = min 2012 = year Now it’s set, as simple as that: [root@linuxtechtips ~]# date Thu Sep  6 15:00:01 SGT 2012 Another example, you want it to change to 20th of December, 2012, 10:45pm [root@linuxtechtips ~]# date 122022452012 Thu Dec 20 22:45:00 SGT 2012 Viola!!! [root@linuxtechtips ~]# date Thu Dec 20 22:45:03 SGT 2012 Now if you want to challenge yourself, then you can use this as well: Using our example date above, use the date comman
