E-mail server configuration – through trial and error

E-mail server configuration can be a pain. Spam was and still is a big problem, especially due to its volume, being almost half the size of all e-mail sent globally. Automated services, filters, reputation monitors and blacklists made it harder for spam to get across in people’s inboxes. It also made it harder for e-mail servers to be accepted as “legitimate” – which is good because it raises the quality level and hardens the requirements, but on the other side, it gives debugging issues.  Continue reading “E-mail server configuration – through trial and error”

WordPress login attempts – observations and conclusions

According to some sources, WordPress  powers approximately 18.9% of all known websites. Not sure of the exact specifics and I don’t think it’s relevant to question them, but I think most people agree that a lot of websites are using WordPress. Which makes it a clear target for both mass and targeted online attacks. Given the fact that like with other software or systems, a lot of WordPress installations are poorly managed by their users from a security perspective, especially when it comes to updates and proper credentials, the ease of compromise increases attracting even more attackers.

Setting up and debugging a PPTP server on Debian

If you want a personal VPN solution that you can host at home or on a VPS, PPTP is the easiest way to do it. Or if you want a VPN test subject, PPTP is also the easiest way to do it. The following will detail how to set up a PPTP server on a Debian (version 7.8) machine. To be understood that choosing PPTP as a VPN doesn’t guarantee a really secure solution , but it can save time and setup issues associated with other alternatives. For a more secure alternative over PPTP, I’d recommend OpenVPN. Continue reading “Setting up and debugging a PPTP server on Debian”

7 things I look for at a VPS provider

03As mentioned in a previous articles on hosting control panels to use for your VPS , buying a VPS is as affordable as or even cheaper than shared-hosting. This is only when it comes down to money/month or year. Other costs or resources would include time and knowledge to actually setup and maintain your VPS. A great way to start lowering those costs is by having a look at free alternatives to CPanel. Continue reading “7 things I look for at a VPS provider”

Email scams – getting money from Industrial and Commercial Bank of China

We all receive spam email. Everyday. Typically they end up in the “spam” folder and we never even get to see them. I never did really care about them and normally erase as soon as possible. This one got my attention as it ended up in my inbox on of my fictive emails (doesn’t everybody has that?) and I decided to play along to see where is everything going.

Free hosting control panels AKA alternatives to Cpanel

Lately I’ve been intrigued by how affordable (or even free) a VPS is nowadays and how (relatively) easy can one host his own website(s). This is determined mostly by ones technical expertise and the tools available at hand. To better manage several websites and everything related to them (DNS,FTP,databases,email and so on) one would use a “hosting control panel”. Tools that hosting providers use to manage customers, customer websites, resellers and tools that are also being made available to end-users to manage their website. The most known in the industry would be CPanel (end-user tool) and WHM (administrative control panel). Their prices can get pretty high and would mostly be suited for companies specializing in web services / hosting.
