Moving SSH off port 22 doesn’t do much for security

A week or two ago, a stranger approached me with some advice about securing routers: move SSH off port 22.

Since arguing with strangers is what the Internet was apparently invented for, I’ll argue against the benefits of moving SSH off port 22.

Change your printer’s IP address in Windows

Sometimes you may need to change your printer’s IP address, such as after you rearrange your network. It’s not hard to do, it’s just not always immediately obvious where the settings are.

This method works in Windows 7 and Windows 10. It probably also works in Vista and Windows 8, but I don’t have those versions anymore.

A DD-WRT USB print server

If your router has a USB port and is running DD-WRT, you can turn it into a DD-WRT USB print server. It can still do wireless duty while it allows your computers to print to your wired USB printer over your wired or wireless network. It’s not very intuitive or user friendly, but it works. Here’s how to set it up with Windows 7. Other Windows versions will be about the same.

When DD-WRT doesn’t work with Charter

I set up a DD-WRT router on Charter’s Spectrum broadband, and had a hard time getting it to work. It wouldn’t pull an IP address on the WAN side, or it would pull a 192.168 address rather than a Charter public address.

Here’s what I had to do to fix it.

How to add a generic printer in Windows 10

Sometimes you need to add a generic printer in Windows 10.

Windows 10 makes the setup of newer hardware pretty automatic, but if you have a legacy or specialized printer that has to be set up as a generic printer in Windows, the process isn’t intuitive. Here’s how to set it up.

Vigilante router security

Last week, Symantec discovered a worm that infects routers and takes measures to make them more secure. For lack of anything else to call it, Symantec is calling it malware, and most of the security echo chamber is probably howling over this, but I think I understand why it was created.

Reversing some WordPress malware

Aug 2016 update: Back in 2015, some kind of spam bot wormed its way into my site. I quickly cleaned it up, then decoded the attack and posted details here. Not long after, the spambot started directing traffic to this post, because it contains enough of the magic words, I guess. Only instead of serving up spam, it’s serving up my analysis. I’d rather you read this than spam, so I’ve left this page up.

On to the original post…

A few minutes ago I received an alert that some files had changed on my site (thanks to All-In-One WP Security). But I hadn’t changed anything and WordPress hadn’t updated itself.

Here’s what I found, and how I fixed it.

Minor-League hacking in the MLB

So, about a year ago, the Houston Astros announced their internal player database had been breached. This week, more details emerged, pointing right at the St. Louis Cardinals.

It wasn’t a terribly sophisticated attack. You knew I’d write about this, but I’ll explore it from an IT security perspective more than from a baseball perspective.

What to do when your router isn’t in the DD-WRT router database

If you have a router and want to run DD-WRT on it, but can’t find the router in the router database, you may have learned the hard way that the router database is a couple of years out of date.

But not all hope is lost. Here’s how to find a build, if one exists.

Why shouldn’t corporations just let software auto update?

I’ve been hearing the same new idea at work for about 10 years. The idea is pretty straightforward: Since my home PC updates itself whenever it wants and I don’t have problems, why don’t we do the same thing at work so we won’t need expensive update deployment tools?

There are generally two problems with that.
