Career as Administrator vs Programmer

O’Reilly Books by mightyohm

I remember almost a year ago I googled for article about this. I’ve been a system and network administrator for more than two years in medium sized company, dealing with Windows Servers, Sun Solaris, IBM AIX, Firewall, and VMWares.

Then, for an unknown crazy reason I applied for a programmer position in one of the biggest software house in Indonesia. I was accepted and suddenly had a dillemma of choosing to stay as an administrator or to shift career as programmer.

Being a good information age generation, I looked for what other people’s opinion in online forums. Some are pros for career in sys and network administration, and some others are pros for career in software development.

To be honest, they made me even more confused. But I finally made my choice.

Now after 8 months of work as Java EE programmer, I want to share about what I know about these two IT careers. Please note that I don’t think one is superior than another although during this article I may be a bit inclined to software development career.

How To Change SMTP Routes On Popular Mail Transport Agents (MTA)

Once in a while you may need to change the SMTP IP destination of your mail relayer server. Last month our company installed a new anti-Spam software using Symantec Mail Security to reduce the significant number of incoming spam email. During this project test and deployment period I need to change the email smtp routes several times. Here I created the documented steps that I did during the process.

Just one comment about the Symantec Mail Security Anti-Spam feature. It is very good software that can help you reduce 99.9% of spam emails. It is 99% accurate in keeping the spam email from going to your inbox. Until now I only receive 1 spam email for the whole two weeks. However it needs to update its database every 20 minutes or less. And this update can take up to 4 GB of internet bandwidth every week. Well, that’s quite a price for keeping spam email out of your email huh!

Allright, back to how to change the SMTP routes of three most popular MTA (sorry, I don’t include Exim cause I didn’t able to tried it..) Continue reading “How To Change SMTP Routes On Popular Mail Transport Agents (MTA)”

Replacing Windows 2000 Printer Server to Windows 2003 Server

The Story:

Last week our Windows 2000 printer server had repeated problems in a single day. As the rule of thumb of Windows 2000 printer server troubleshooting says, I stopped the printer spooler service, waited a few seconds, and then started the service. Based on my experience, most of Windows service will show an fail message when I clicked on the restart service button. That’s why I prefer to click on the stop button and the start button after several seconds.

Anyway, it did solve the problem for about half an hour until the next user complained that she cannot print also. Then I restarted the Windows to make sure all the troubles caused by any lack of available memory resources will be solved. It came up and it solved the print problem.

But a few hours afterward the problem re-occured and so I did the restart ritual of both service and Windows all over again. I thought that was all for that day, but on the following day I discovered that my work colleague restarted the Windows once more after I left the office because of the same problem.

The problem no longer occur until today, but me and my work colleague has worked on plan to replace the printer server to new hardware and upgrade it to Windows 2003.

As always, we tried it in a testing environment with very similar condition. Here are the steps to upgrade Windows 2000 printer server to Windows 2003. Continue reading “Replacing Windows 2000 Printer Server to Windows 2003 Server”

Copy Files and Folder Across Partitions and Maintain the Folder Permission and Access Control List (ACL)

Scenario:

Last weekend we added a new storage for company File Server. We need to move all the Departments’ folders to the new storage while maintaining the folder security permission. There are thousands of folders inside around 50 different main folders. We certainly cannot afford the chance of losing the folder permission security properties that already created for several years.

What I know is Windows Server 2003 can only retain these security properties if the folder is copied in the same partition. While if you copy the folder across different partition, it will remove all of the security properties. Sounds like disaster to me…

My work partner then told me about the xcopy command that can be use to solve the issue. Continue reading “Copy Files and Folder Across Partitions and Maintain the Folder Permission and Access Control List (ACL)”
