LXC 0.7 in Gentoo Linux – updated

Jun 25

Posted by Marius Staicu in Linux | 5 Comments

LXC 0.7 is available as an upgrade in Gentoo Linux. After you get it you may have a surprise… no console output after lxc-start. It seems it is not a bug but a feature :) (as always with software). To get back the output just add -s lxc.console=$(tty) to the command line, like:

# lxc-start -n machine_name -s lxc.console=$(tty)

It does not look 100% like before but at least you get some feedback and are able to login. And it seems the shutdown does not work as well as expected (this has to be investigated over weekend).

This is fixed in 0.7.1

Update The poweroff now works and it stops the container as well. Nice job :)

LXC with Gentoo Linux

Jun 3

Posted by Marius Staicu in Linux | 7 Comments

VMWare (Server, Player, ESX), VirtualBox, KVM/QEMU  are just a few of the virtualization technologies you can use if you need to run a generic virtual machine. Each has strong and weak points, each adds some overhead when running the virtual machine, each can prove useful in a given scenario. I’ve used more or less extensively all of them (testing or in daily work). I’ve tested also linux specific virtualizations like XEN or OpenVZ but their drawbacks made me somewhat reluctant in using them. But recently I’ve come over Linux Containers (LXC), a lightweight virtualization that lets you isolate processes and resources without using a full virtual machine. Read the rest of this entry »

SSH TCP Port Forwarding aka poor man’s VPN

Apr 15

Posted by Marius Staicu in Linux, System Adminstration | 16 Comments

In today’s world when the IPv4 addresses are a luxury and IPv6 is not wide deployed (yet) more and more servers are running behind NAT-ed addresses. To do remote management on these servers you connect to them using SSH through some port forwarding done on the border gateway. If you need to monitor these servers there are a few alternatives:

  • more ports forwarded from the gateway
  • use a vpn to  connect to the remote network
  • use TCP port forwarding through the SSH connection

This post will show how you can obtain more from the existing SSH connection to the remote system.

Posted by Tomita Militaru in Linux | No Comments

A problem that many web developers face when they switch from Microsoft Windows to an open source operating system (Ubuntu, Fedora, Archlinux, OpenSUSE, Mandriva, Debian, BSD etc.) is the imposibility of running tests on Internet Explorer, since IE is officially suported only on Windows.

NTFS partition resize with free tools

Jun 26

Posted by Marius Staicu in Linux | No Comments

Last week I need a new partition on my external drive. The HDD has 80Gb split in 2 partitions, one of 20Gb and one of around 56Gb. The first partition was nearly full and the second had 30Gb of free space (but with many fragmented files). The obvious solution is to move the 26Gb from the second partition to another drive, delete it and create 2 smaller ones. But if you don’t have the 26Gb of temporary space there is another solution: shrink the second partition and create a new one in the free remaining space. This can be achieved with Partition Magic but the tool is not free. (You can download a trial version and see if it is working but using free tools is better – and I was eager to see if it is possible). The process I’ll describe below is simple and can be applied to any external HDD drive with ntfs partitions (and probably other types, by using the correct tools).
