I didn’t write in my blog since Eid Aladha, I was working with FOSsiL group for Linux day in Libya preparation and that take most of my time.

Now I’m  back :d

Finally Linux day in Libya !!!, Linux day in Libya-Tripoli in 24 Jan 2009 will be held at the ALiemad tower, Ubuntu will send CD’s and sitcker for this day ” Thanks Ubuntu- Jono Bacon ” for his help .

for more info about the day visit F/OSsiL website http://fossil.ly

If you have multiple servers with similar or identical configurations (such as nodes in a cluster), it’s often difficult to make sure the contents and configuration of those servers are identical. It’s even more difficult when you need to make configuration modifications from the command line, knowing you’ll have to execute the exact same command on a large number of systems .

In this tutorial we will see some tools to execute one command on multiple remote servers using ssh.First you need to make sure you have ssh installed in your machine or you can install using the following command

sudo aptitude install ssh

Now we are going to see the following tools which does the required job we are looking for

1) Pssh

2) cluster ssh

3) Multixterm

1) Pssh

pssh provides a number of commands for executing against a group of
computers, using SSH. It’s most useful for operating on clusters of
homogenously-configured hosts.

The package contains:

- Parallel ssh (parallel-ssh, upstream calls it pssh), executes commands on multiple hosts in parallel

- Parallel scp (parallel-scp, upstream calls it pscp), copies files to multiple remote hosts in parallel

- Parallel rsync (parallel-rsync, upstream calls it prsync), efficiently copies files to multiple hosts in parallel

- Parallel nuke (parallel-nuke, upstream calls it pnuke), kills processes on multiple remote hosts in parallel

- Parallel slurp (parallel-slurp, upstream calls it pslurp), copies
files from multiple remote hosts to a central host in parallel

These tools are good for controlling large collections of nodes, where faster alternatives

Two days ago F/OSsiL website goes online, I want to thank all colleagues in Libyan Spider Network for their generous help, FOSsiL will be the official board for this group and all activity will realease on it, FOSsiL preparing for Linux Day in Libya. for more info go to FOSSIL.LY

As the FOSS is getting high attention from different entities in the world, just to mention the UNDP and the European Union, and because of the Technical Committees and Groups around the glob in addition to the number of researches, papers, conferences and meetings, and the different reports about FOSS, we established the Free and Open Source Software in Libyan Group (FOSSiL group) to formalize the efforts and activities that will be in Libya related to this field. We have as one of our main goals is to open the opportunities for our Computer Students within different colleges and institutes, programmers, computer engineers, and enthusiastic in Libya to benefit and to participate in developing huge software packages and exchange with engineers with high experience to improve their performance and have the best and effective way of Knowledge Transfer.
In the following sections we will present the Open Source Definition that is initiated and applied by the Open Source International. It will be followed by two sections each for one of the most commonly used Open Source Software Licenses.

Free and open source software

Its goal is to provide a comprehensive compilation of tools which, when working together, grant a network/security administrator with detailed view over each and every aspect of his networks/hosts/physical access devices/server/etc…
Besides getting the best out of well known open source tools, some of which are quickly described below these lines, ossim provides a strong correlation engine, detailed low, mid and high level visualization interfaces as well as reporting and incident managing tools, working on a set of defined assets such as hosts, networks, groups and services.

Don’t panic if you deleted /etc/fstab by mistake you can recover it from /proc by the following this way :

cat /proc/mounts > /etc/fstab
chmod 644 /etc/fstab

The “proc” filesystem, which is /proc/mounts, is used to handle sytem configuration parameters, it is a virtual filesystem.

For those of you who don’t know, Vyatta is an open source network appliance that functions as a router, firewall, and VPN device, all running on a customized version of Debian Linux. I have been following the progress of Vyatta for over a year now, and things are looking very promising. The latest release is called VC4 (Vyatta Community edition) and it includes a bunch of useful new features:

• New command shell allows you to modify Linux settings and network settings from one common interface
• Redesign of routing protocol offers greatly improved stability and performance
• Role-based user access
• Equal-cost multi-path routing
• Remote access VPN
• Support for IP tunneling protocols
• PPPoE support, commonly used with DSL connections
• WAN load balancing of outbound traffic across two or more WAN-facing interfaces
• Quality of Service policies provide congestion management and traffic conditioning

As you can see, a lot of exciting changes have been made in the short six months since the previous release. The routing improvements are related to the change from XORP to Quagga. The added QoS capabilities will make Vyatta a good fit for VoIP deployments. The only negative to this release is that Vyatta had to temporarily remove the GUI web-interface until they can integrate it, which is scheduled for July, 2008. Overall, Vyatta is becoming a a compelling option for replacing some of your over-priced network equipment. Read the rest of this entry »
