Why does mysql keep inserting data in random places and how can I fix this?
by on Sep.21, 2010, under LAMP
I am using mysql 5.0.51a with php 5.2.5
I am using the insert command to enter data.
It keeps inserting data in random locations in the table, which is messing up my web app.
It did use an id column at one time.
I’ve tried flushing the table, and remaking the table with phpmyadmin’s sql dump.
How can I fix this? I just want mysql to insert data at the end of the table, like it should.

How different is a Linux network compared to a Unix network? I understand a Unix network has mainframes, etc.
What are the things a Unix network has but a Linux network does not have and can never have?

Six Steps to a More Secure Linux Server | Online Security Blog (OSB)
by on Sep.19, 2010, under LAMP
I’ve worked as a remote Linux system Administrator for quite a while, and one thing that I’ve noticed is that many “administrators” out there don’t know how to configure or secure a server properly. This article is a quick reference on some of the more important (and easy) security or configuration tweaks that any administrator should do for their server. These six steps can dramatically increase the security and stability of any Linux server. The best part about these tips, is that they are all quick and easy to do as well, with each step taking less than 15 minutes!
1.) Security Updates not Installed Nearly every server that I work on is not running the latest (and most secure) software. yes, Linux is a great Operating System- but all software has security problems. Enabling the installation of automatic updates via a cron script or similar is the easiest and most foolproof way to ensure that your server isn’t compromised. There really isn’t any excuse not to install the latest security updates- older packages are saved in the package archives in case there is a stability or compatibility issue, and the updated packages are logged as they are updated.
2.) Disable root login via SSH, and password authenticationAdmittedly, I’ve been guilty of this myself sometimes. Let’s face it, everyone likes being able to quickly and easily log into their servers, and change settings. However, if you’re using password authentication, what’s to keep someone else from logging into your server? in addition, you should not use password authentication on your Linux server, to prevent others from logging into your Linux server. Instead, enable RSA signed authorization keys. This is more secure, since an attacker will not be able to guess or brute force a login session with your server.
3.) Disable or filter extra services This is the second biggest issue that I see working with new client’s servers. Often, the system administrator who setup their Linux server did not perform a necessary final step- filter incoming connections that aren’t necessary. I’ve seen everything from the daytime service running, to MySQL listening for connections on a remote IP. if a Linux administrator is not familiar with iptables, there are several tutorials out there that will show someone how to create even a basic firewall ruleset. in addition, disabling unnecessary services is a basic step in server optimization as well- why run extra services that tie up resources if they aren’t needed?
4.) Test accounts or guest accounts still activeAnother glaring security issue (and an often exploited one) is that a client will still have test user accounts running (often with extremely easy passwords, such as test) once a software solution is deployed to a production server. I don’t need to go into the security ramifications with this one- make sure that you get rid of those guest or test accounts!
5.) Advertising banners left on We all love advertising, don’t we? However, advertising to the world that the version of Apache or Sendmail that you run on your Linux server is 3 years old is not the type of attention that you want. Simply disabling the server banners will help hide your server from the basic script-dependent attackers. Besides, why help the bad guys determine what software your server is running?
6.) PHP errors or application errors I’m pretty confident that we have all seen an error or two displayed on a website. some errors that are displayed are not a security issue at all, for instance Javascript errors. However, some errors are security issues (PHP is particularly bad with this), because they disclose sensitive information. The easiest way around this is to disable displaying errors in PHP (or your web applications). otherwise, an attacker may be given information about your website’s database details, or file locations.
These issues are the top 6 security issues that I see on a daily basis in my work. you can all check your server or servers for these quick issues (these tips take almost no time at all), and dramatically increase the security of your server. However, if you have any problems implementing these security steps, please feel free to contact me.

Hal Helms On Web Development: Ready to Learn Ruby on Rails?
by on Sep.19, 2010, under Ruby and Rails
Well, the internet is roiling with accusations, conspiracy theories, cross-complaints — you name it — regarding Apple’s much ballyhooed smackdown on Adobe’s Flash. I found this comment to be particularly telling:
“The iPad is an anti-technology device targeting consumers who are too lazy/stupid to use or want a keyboard or mouse or stylus. why should a website focusing on tech-savvy people modify their code to play along with the silly-ass marketing scheme Apple plays making its airhead users _think_ they’re some kind of pioneers?”
Let’s stipulate that Apple is not too fond of Adobe. why? Who knows. and it was particularly cold-blooded of them to let Adobe develop their Flash-to-iPhone technology, dropping this bombshell only a few days before the release of CS5. Let’s stipulate, in fact, that Apple is bristling with its own power — and is using it with shocking disregard for what other members of the tech community think.
But we techies miss an important point that Apple does not: computers are too damned hard for normal people to use. In the tradeoff between power and ease-of-use, techies will always choose power. Apple really does seem intent on making a computer “for the rest of us” — and that means that power must/will be sacrificed to make the device(s) simple to use. and reliable. and having a decent battery life.
Does Apple’s decision to cut Flash off at the knees make sense? it depends on whose interests you’re thinking of. Is it good for you and me who crave all the power we can get? No. but is it good for the vast numbers of people who just want a computer that works and are frustrated by the unintended side effects of power run amok? Reluctantly, I have to say yes.

Linux Slackware – Remote login?
by on Sep.17, 2010, under LAMP
Hi there,
I’m running Linux Slackware 10.1. with Apache. I use the machine only for home experimental use (scripting etc) and generally shut it down when not in use. My question however relates to when I boot the system up, as I now need to remove the monitor it uses to use on another machine. Therefore, is it possible, once the machine has been turned on and booted to the log in prompt to login remotely from another system?
The only time the monitor actually gets used is to see the login and password process, and then everything else is done remotely (Telnet/CRT etc). I even shutdown remotely, but not sure if I can login remotely (as root or supperUser). It’s such a waste to have a monitor in use for just that 10-second process only, when it could be used for something else (in this case, a system about to run Linux Ubuntu).
Any assistance is much appreciated.
Regards,
Rob
