Two Firefox add-ons to increase your productivity

January 18th, 2010

Below are two firefox add-ons productivity tools that should make your life a lot easier :

QuickFox Notes :

This is a note-taking add-on for Firefox that saves notes as bookmarks in Firefox. This means you get all the convenience of browser-based note-taking, and cross-browser syncing if you’re using Mozilla Weave, Xmarks, or another method to sync your bookmarks between instances of Firefox.

Read It Later :

Read it Later is an extension that works with a Web-based service.  Here’s how it works. Once you install the extension, RiL adds a yellow icon to the “Awesome bar” in Firefox, and a similar icon to the toolbar next to your search. When you’re on a page you want to save for later, just click the yellow icon.

Google Reader fans will also love RiL because it will also clip items from Google Reader without having to view the page first. Once the extension is installed, it adds a RiL icon to Google Reader items (right next to the star). Just click that and the entry will be added to.

HP to acquire 3Com Corporation

November 26th, 2009

On November 11, 2009, HP and 3Com Corporation announced that they signed a definitive agreement for HP to acquire 3Com, a leading provider of networking switching, routing, and security solutions. The acquisition would create an innovative, networking leader that will transform the networking industry with a global reach.
The acquisition would create a robust set of end-to-end networking solutions in a $40B market. It would combine HP ProCurve networking strengths in the LAN edge with 3Com strengths in Core switching. 3Com would also offer the opportunity to add a leading security offering with its TippingPoint business.

The combination of HP and 3Com would offer customers a superior networking alternative.  Together, the combined businesses would provide customers with a comprehensive set of enterprise-class solutions based on open, industry standards and innovative technology that simplifies the network, delivers best-in-class price-performance, and improves IT service delivery capabilities.

With the addition of 3Com, HP expects to become the #2 enterprise networking vendor worldwide and significantly strengthens HP’s position in one of the fastest-growing markets in the world, China. HP also plans to build upon 3Com’s presence in China to fuel continued innovation.

The enhanced networking solutions would leverage the capabilities of the largest technology company in the world (#1 in servers, #1 in storage) and its global reach (extensive worldwide customer relationships, 154,000 partners) to deliver better business outcomes to the full spectrum of customers, from Fortune 100 enterprises to small businesses.
The acquisition is expected to close in the first half of calendar year 2010.
Customer value

With the addition of 3Com, HP would deliver a comprehensive and innovative set of enterprise-class networking solutions that simplify the network, drive best-in-class price-performance at the lowest total cost of ownership, and transform the network from a connectivity tool to a business enabler.
HP, with a focus on purposeful innovation based on open, industry standards, enables customers to break free from the limitations imposed by expensive, rigid, and proprietary networking infrastructure. This not only reduces acquisition and operations costs but also creates flexibility for customers to deploy best-in-class solutions—which include market-leading partners.

The enhanced networking solutions would further accelerate HP’s next generation data center architecture strategy, the HP Converged Infrastructure architecture. Underpinned by the robust, end-to-end HP networking offerings, the HP Converged Infrastructure helps customers rebalance their innovation-operations/maintenance ratio, makes adminstrators more productive, enables faster time to value, improves service levels, and increases capacity utilization, all leading to an IT environment that adapts to the most demanding needs and delivers better business outcomes.

Using Clam AntiVirus to provide real-time protection for your iFolder 3 Server

September 13th, 2009

“Because iFolder is a cross-platform distributed solution, there is a possibility of a virus infection on a platform migrating across the iFolder server to other platforms, and vice versa. You should enforce server-based virus scanning to prevent viruses from entering the corporate network.”

This solution applies for openSuSE 11.1 :

The following packages need to be installed :

clamav
dazuko
postfix

Execute modprobe dazuko (as root)

Run lsmod and check that dazuko is loaded:

Edit /etc/init.d/boot.local

  • Add:
    modprobe dazuko

Edit /etc/clamd.conf

Enable logging by activating :
LogFile /var/log/clamd

* Activate:
# Path to a local socket file the daemon will listen on.
LocalSocket /var/lib/clamav/clamd-socket

* Deactivate:
# TCP port address.
#TCPSocket 3310

* Deactivate:
# TCP address.
#TCPAddr 127.0.0.1

* Activate and edit:
# Execute a command when virus is found.
VirusEvent /bin/echo “iFolder VIRUS ALERT: %v” | /bin/mail -s “ClamAV - iFolder” -r ClamAV@server.domain ToUser@domain

* Deactivate:
# Run as a selected user (clamd must be started by root).
#User vscan

Note:
If not deaktivating “User vscan” you receive the error: “clamuko cannot connect to dazuko” in /var/log/clamd

* Clamuko settings, Activate the following :

ClamukoScanOnAccess yes
ClamukoScanOnOpen yes
ClamukoScanOnClose yes
ClamukoScanOnExec yes
ClamukoIncludePath /YOUR_PATH_TO_IFOLDER/ifolder/simias/SimiasFiles

Change any other settings in the file to reflect your needs (see ClamAV documentation).

Start clamd:
/etc/init.d/clamd start

Check that clamd was started without any errors:
tail -f /var/log/clamd

Download the EICAR test signature from:
http://www.f-secure.com/virus-info/eicar_test_file.shtml

Note!
This is not a real virus.

Run: tail -f /var/log/clamd

Save the test file (eicar.zip and/or eicar.com) in your iFolder and wait for sync.

When the virus pattern is detected you should see this (see below) in the log file
/var/log/clamd.

Check that a mail has been sent: tail /var/log/mail

Update ClamAV:
You can update ClamAV using the command: freshclam

A better way is to use the freshclam daemon for automatic updates.

Settings for freshclam: /etc/freshclam.conf

Edit /etc/freshclam.conf

  • Activate:
    # Path to the log file (make sure it has proper permissions)
    UpdateLogFile /var/log/freshclam.log
  • Activate and provide your country code:
    # Uncomment the following line and replace XY with your country code.
    DatabaseMirror db.se.clamav.net
  • Activate and provide update interval (e.g 24 for every hour):
    # Number of database checks per day.
    Checks 24

Create a log file for freshclam:
touch /var/log/freshclam.log

Set file rights:
chown vscan:vscan /var/log/freshclam.log

Start freshclam:
/etc/init.d/freshclam start

Check the log file:
tail /var/log/freshclam.log

Activate automatic start for clamd, freshclam and postfix from Yast –> System –> System Services (Run Level).

Now you have a real-time anti-virus scanning for your iFolder3 server.

Basic FTP Commands

September 2nd, 2009

The FTP (File Transfer Protocol) utility program is commonly used for copying files to and from other computers. These computers may be at the same site or at different sites thousands of miles apart. FTP is a general protocol that works on UNIX systems as well as a variety of other (non-UNIX) systems.

Find below a listing of basic FTP commands :

? to request help or information about the FTP commands
ascii to set the mode of file transfer to ASCII
(this is the default and transmits seven bits per character)
binary to set the mode of file transfer to binary
(the binary mode transmits all eight bits per byte and thus provides less chance of a transmission error and must be used to transmit files other than ASCII files)
bye to exit the FTP environment (same as quit)
cd to change directory on the remote machine
close to terminate a connection with another computer
close brubeck closes the current FTP connection with brubeck,
but still leaves you within the FTP environment.
delete to delete (remove) a file in the current remote directory (same as rm in UNIX)
get to copy one file from the remote machine to the local machine
get ABC DEF copies file ABC in the current remote directory to (or on top of) a file named DEF in your current local directory.
get ABC copies file ABC in the current remote directory to (or on top of) a file with the same name, ABC, in your current local directory.
help to request a list of all available FTP commands
lcd to change directory on your local machine (same as UNIX cd)
ls to list the names of the files in the current remote directory
mkdir to make a new directory within the current remote directory
mget to copy multiple files from the remote machine to the local machine;
you are prompted for a y/n answer before transferring each file
mget * copies all the files in the current remote directory to your current local directory, using the same filenames. Notice the use of the wild card character, *.
mput to copy multiple files from the local machine to the remote machine;
you are prompted for a y/n answer before transferring each file
open to open a connection with another computer
open brubeck opens a new FTP connection with brubeck;
you must enter a username and password for a brubeck account
(unless it is to be an anonymous connection).
put to copy one file from the local machine to the remote machine
pwd to find out the pathname of the current directory on the remote machine
quit to exit the FTP environment (same as bye)
rmdir to to remove (delete) a directory in the current remote directory

Installing iFolder server on openSuSE 11.1

August 24th, 2009

iFolder is a simple and secure storage solution that can increase your productivity by enabling you to back up, access and manage your personal files-from anywhere, at any time. Once you have installed iFolder, you simply save your files locally-as you have always done-and iFolder automatically updates the files on a network server and delivers them to the other machines you use.

Using iFolder, you can designate any network server as an iFolder server and publish information to a personal iFolder created on that server. Once your folder is established, you can install iFolder on the computers you regularly use and download information from your personal iFolder to any of those computers. Not only that, but using iFolder, you can also invite other iFolder users to share your files in the same safe and secure way so that your teams always have the most relevant copy of a document.

You can download iFolder server for openSuSE 10.3 from this URL : http://www.ifolder.com/download/

But installing iFolder server on openSuSE 11.1 is a bit tedious as mono packages packed with version 11.1 are a bit advanced for iFolder. Find below instructions to help you out :

- Install iFolder server and plugins from this repo.

- Configure apache2 with SSL support.

- Setup by typing as root :

simias-server-setup

ifolder-admin-setup

ifolder-web-setup

in console and follow question given by each command.

- Change folder directory to /etc/apache2/conf.d by cd command and copy all .conf file to /etc/apache2 with cp command on console.

- Start apache service by typing service rcapache2 start in console.

- Allow services http and https in Firewall.

And you’re done.

IMPORTANT :

If you experience the following error code while the client is trying to connect to the server : Authentication Status Code: Unknown. The problem can be solved by NOT choosing the default server data location while running simias-server-setup. I have chosen /home/iFolder instead and that solved my problems. The server will create the folder for you with correct setup and permissions.

I would like to thank http://www.decriptor.com/2009/05/22/ifolder-on-opensuse-11-1/ for helping in creating the repository and making the above information available.
