I’ve written before how to get a standard PCI dual NIC for a low, low price–but what about a PCIe dual NIC? PCI Express needs love too, of course.
It turns out it’s not hard to find a good, cheap PCIe dual NIC either.
I get a lot of questions about the DD-WRT firewall. There’s a lot of talk out there that goes deep into theory and advanced firewall usage, but what if you just want to know how to set up your firewall to protect your network and open up a few ports?
Here’s how to set that up.
Note: If you have multiple DD-WRT boxes running as access points like I do, only the one directly plugged into the Internet needs to be configured this way. Disable the SPI firewall on your internal access points.
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.
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.
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.
So I understand ISPs are upselling connection speeds saying it’ll make Netflix work better. That’s a nice theory. But if you’re already over 10 megabits, there’s a decent chance your connection speed won’t do much for Netflix at all. Here’s how to size your Internet connection. Read more
I was doing some scanning with a new vulnerability scanner at work. It found something listening on a lot of servers, described only as Apache and OpenSSL listening on TCP port 2381. The versions varied.
Luckily I also had Qualys at my disposal, and scanning with Qualys solved the mystery for me quickly. It turned out to be the HP System Management Homepage, a remote administration/diagnostic tool that, as the title says, lets you manage HP server hardware. It runs on Windows, Linux, and HP-UX.

Sometimes you have to manually add a TCP/IP printer in Windows 10. For example, I have an older HP Laserjet 4100 with a Jetdirect card in it that I use to print from all of my PCs over my local area network (LAN). Getting Windows 10 to print to it isn’t difficult but it’s hardly intuitive.
If you have your printer already set up but just need to change its IP address, I covered that here. If you want to share a locally attached printer with other computers on your network, you can do that too.
A longtime friend’s aunt almost got taken by a fake tech support scammer. He told me about it, and in the process, this was also the first I’d heard of the netstat scam.
She saved herself by saying she’d have to check things out with her nephew first. That’s a good trick. Fortunately for her, the scammer didn’t try to delete anything, though he did immediately change from being very pleasant to being very rude. That matches my recent experience with these low-life crooks precisely.
She was vulnerable because the flawed MS14-045 gave her trouble and she had a case open with HP. So when this crook called, she thought at first that HP or Microsoft were folllowing up with her about that.
The scammer’s best trick was to get her to open a command prompt and type netstat. Read more
I’ve been listening to Patrick Gray’s coverage of the AusCERT security conference, and I walked away with two major takeaways, one for security professionals and one for everyone.
Everyone first: Use SSL (https) everywhere you possibly can. Generate superfluous https traffic if you can.
Network professionals: Block as much UDP at the firewall as you can.
