A weird Messaging problem occured on my one-week-old Sony Ericsson 960i handphone. When I viewed the SMS list from the Messaging application, only the senders’ numbers appeared (normally, the senders’ names will appear instead if they are in my Contact list). Furthermore, when I tried to view any of the SMS, an error message saying the message is incomplete is prompted to me followed by another error message saying Access is denied .

This immediately triggered a severe panic sensation as I frantically searched the internet to look for any causes/solutions for this problem. After reading up all the available information, I gather that the cause of the problem is most probably to do with my Contact entries. It’s weird since all my contacts are imported on the day I received my phone and I’ve only added a couple of new entries. I deleted all the new entries (and some junk contacts that I can’t even remember how they got into my list) and rebooted the phone, it was still giving me the errors. When I was about to give up and schedule a suitable time to bring my baby to the clinic, it hit me. I added some voice dial commands the day before and when I tried to voice dial today, it failed. After that incident, the weird Messaging problem started.

I quickly deleted all the voice dial commands and viola, the Messaging problem went away.

So, for those who get the same error messages shoved into your face, the problem most likely lies in your contact entries.

Scenario: You have one Oracle database with 3 different SID for different purposes: DR (disaster recovery), UAT (User Acceptance Testing) and SIT (System Integration Testing). You are tasked to configure the Database to open one port for each of the SID to control access. Piece of cake, you will only need to edit two oracle configuration files to achieve it.

Scenario: Your AIX server has OpenSSH installed and sFTP configured. How do you restrict sFTP users from accessing other shells (like ksh, bash, csh, scp, ftp, etc)? How do you prevent them from traversing through your directories and potentially doing all sorts of damage?

The answer: Set up rssh with chroot jail. Restricted shell (rssh) is a replacement for the standard shell (in AIX’s case, ksh) to be used with OpenSSH that lets you restrict shell access to only sftp and scp. It supports chroot jail which is a method to sandbox users and programs in a specific directory. Read the rest of this entry »
