Recently I had a task in which I had to create dkim keys for a massive amount of sites for a server. Since, I haven’t made a post in awhile, I figured I might share my helper script with the world. This script has been made with opendkim in mind, mostly because that is what was used on the server where I had to implement this. In some server setups, it would be highly probable that another mean is used to establish dkim keys, for those guys… I’m sorry, this is not the article for you. Continue reading

The Server Control Panel
Here’s a follow up from the previous post I made couple months ago here. I’m not sure if there is a better way, but I’m thinking perhaps the best way to stay ontop of configuration file changes is using something like mmonit. Using this we would monitor when files actually change to reload a mapped out configuration into the sql database for easy access & ease of manipulation in the database. Otherwise, we could do something directly like how virtualmin/webmin works, in that we would reparse configuration files every time and save on demand. The biggest problem I see with this, is well, I’m sure not if PHP will really be the best choice for parsing configuration files every single time when pages related to… Continue reading
Video Training Websites
There are numerous video training websites, probably the best known is lynda.com. But what are the other, possibly lower cost alternatives? This post, I’m just going to simply explore all the various options out there. Keep in mind also, I have not used all of these video training websites but I am going to do my best to explore the collective opinion of others on the net the pros and cons of each. Paid Alternatives TeamTreeHouse Treehouse isn’t necessarily competitive in price in comparison to Lynda, being their plans are either $25 and $50 a month. However, they boast their selves on a better learning experience. When it comes to code, they have a “code challenge engine”, which you can actually proven our skills once… Continue reading
Call for New Server Configuration Platform
Everyday I take a look at the tools I have for server configuration, and everyday I realize I have less & less of what I really want. I’ve used many server configuration programs over the day, from Plesk, to Cpanel, to ispconfig, webmin, virtualmin, and many many more. Well, when it comes down to it, probably the best option out there that I’ve encountered so far is a cross somewhere between cpanel & virtualmin. I use cpanel for my production servers where I sell shared hosting, and then I use ISPConfig these days for my own personal servers. Now, before you read this and go pish posh, who needs graphical GUI’s for server administration. Well, I understand where your coming from, which if I didn’t… Continue reading
PHPProxies
Proxy “Proxy” is no longer just some obscure legal term. Now internet proxies are used by everyone from students and workers to people living in countries like Iran or China where the government censor their citizens traffic.

This website contains all the resources you need to anonymize yourself, or start your own personal… Continue reading
Dynamic DNS
Dynamic DNS? How to do it? Yes so there are howtos out there, but unfortunately none of them were complete enough for me. Client Side First you will need to create your keys for this work. This process is well documented and described on another site, so I won’t repeat how to do this. Instead I’ll just give you the link http://linux.yyz.us/nsupdate/ Beyond that.. The site seems to lack, it tells you the basics how to update it though not quite a script on how to do it easily enough. So I devised a simple shell script without using a dhcp to update the IP address. Server Side Again I don’t like beating a dead bush. The previous site gives great information on how to… Continue reading
