SIM Card Registration Failed Solution

Few days ago I sent a message on twitter "Anyone know the reason for Nokia's SIM Card Registration Failed problem?". Got quite a few solutions from my friends . It is the most common problem with Nokia mobile phones. Restarting the phone few times or removing SIM and cleaning the contacts also fixes the problem. Try some of the solutions that worked for me. Solution 1: Blocked SIM or Faulty SIM In countries like India, you need to register your SIM card. The cell phone company blocks the SIM if they don't receive the application within few weeks of activating the phone. Please check if this is case. Take out the SIM and test it with a different phone, if the phone fails to read the SIM, get the SIM replaced. Few days ago this worked for a friend with a brand new Nokia handset here in Hanoi, Vietnam. Solution 2: Clean SIM Contact Pins Take out the battery and SIM card. Use a clean eraser to wipe the gold contacts of the phone and on back the SIM card. Replace the …

How to install Sun JDK on Ubuntu 10.10 “Maverick meerkat”?

Managing Creative ZEN Mozaic with mtp-tools

Using the Creative Zen Mozaic in Ubuntu 10.10 is a nuisance. The ubuntu standard Rhythmbox Music Player has problems with this MTP portable player. In previous version of Ubuntu Gnomad2 was used to manage these devices, but it is no longer available in latest verion. My solution is to use the mtp-tools on command line. You can install the package by typing the following line on the terminal or use Ubuntu software center program.
sudo apt-get install mtp-tools Next get rid of the Gnome Gphoto2 VFS program that will try to automount the device as a camera.
killall gvfs-gphoto2-volume-monitor Now you are all set. Connect the device and lets see if we can detect the player with mpt-detect command. $ mtp-detect libmtp version: 1.0.3 Listing raw device(s) Device 0 (VID=041e and PID=4161) is a Creative ZEN Mozaic. Found 1 device(s): Creative: ZEN Mozaic (041e:4161) @ bus 1, dev 6 Attempting to connect device(s) USB low-level info: Using kernel interface "usbfs" …

Change Samba Password Expiry Setting with pdbedit

We have a Zentyal (Formerly EBox) Linux Small Business Server running as our office file/print server. Its runs smoothly hardly needs any maintenance. Except for this one issue, every few weeks I hear complains from staff that they can't logon to file server. Quick peek at the Samba server logs reveals that 'password expired'. So there is password aging setting in force here. [2010/12/05 17:33:45, 1] auth/auth_sam.c:sam_account_ok(179) sam_account_ok: Account for user 'tom' password expired!. [2010/12/05 17:33:45, 1] auth/auth_sam.c:sam_account_ok(180) sam_account_ok: Password expired at 'Sat, 04 Dec 2010 15:20:57 SST' (1291515657) unix time. Lets remedy that using Samba pdbedit tool. We are gonna reset the 'Password must change' policy to all the users on the server. Zentyal uses LDAP to manage the passwords, so we use '-b' option to point to the LDAP backend. And we change the default policy to passwords never expire. pdbedit -b ldaps…

KeePassX Cross Platform Password Manager

Ask me my phone number, I have to look it up. But I do have uncanny memory for passwords. May be I type them so often that they are etched in my brain.If you have manage a large set of usernames and password KeePassX is a good choice. It is good way to manage all your access information for the a SME organization. You can organize the data into different categories (Local Networking information, Mail Server, Webserver, Emails account information etc) Automated password generation is another feature that I use often. You can choose the length of the password and the combination of numeric, special characters. Its cross platform available for multiple operating systems so if your boss uses Windows, it will still work.

KeePassX FeaturesExtensive management- title for each entry for its better identification
- possibility to determine different expiration dates
- insertion of attachments
- user-defined symbols for groups and entries
- fast entry dublication
- sorting entries in groupsSe… HTML5 accessible wordpress website

Few weeks ago I received a email from Ted Moallem, we collaborated on Blind Lead project in August this year. The project website seems to be inaccessible to screen readers users. Ted used the latest version Wordpress 3.0 content management system (CMS), but Black Letterhead wordpress theme and the page structure were creating some problems.Decided to attempt redesign the website using HTML5. HTML5 offers many accessibility improvements with new elements, ARIA landmark roles etc. Initially I thought of building with Starkers HTML5 theme. However Wordpress ships with a HTML5 complaint theme Twenty Ten so I decided to stick with it. Added some rounded corners, little bit of typographical changes, disabled the sidebar widgets for now. And the site looks better already. Next I set about cleaning up the inline styles in the page content. Some of the styles were introduced by the wordpress editor and other external editors.The pages structure needed some re-organizing as we…
