Linux 3.13-rc1 is out

Linus Torvalds has announced on Friday, November 22, 2013, that the first Release Candidate of the upcoming Linux kernel 3.13 is now available for download and testing.

In numbers, Linux kernel 3.13 RC1 is comprised of mostly updated or new drivers (55%), architecture code (18%), network updates (9%), and the rest of of 28% represents filesystem updates, tools, headers, and documentation.

"So you had an extra week to prepare your pull requests, and if you were planning on sending it in the last two days thinking I'd close the merge window on Sunday as usual, I can only laugh derisively in your general direction, and call you bad names."

"Because I'm not interested in your excuses. I did warn people about this in the 3.12 release notes. As it was, there were a few people who cut it fairly close today. You know who you are." said Linus Torvalds

Featurewise, the big ones are likely the nftables and the multi-queue block layer stuff, but depending on your interests you might find all the incremental updates to various areas interesting. There are some odd ones in there (LE mode Powerpc support..)

You can download the latest rc1 from kernel.org website.

Note: Remember that this is a development version and it should NOT be installed on production machines. It is intended for testing purposes only.

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
