Convert a list of hostnames to a list of IP addresses

I had a client with a huge list of hostnames that they needed to convert to IP addresses so they could scan them. That’s common. I used to have a Windows batch file to convert a list of hostnames to a list of IP addresses, so I dug it out of my archives. This uses ping but isn’t like a ping sweep; they knew the machine names but their tool needed IPs.

I used the file to resolve lists of machines so I could load them into a centralized logging or vulnerability management system. This client had the same need and nobody there had a similar tool. So I shared mine with them. And I present it here so I won’t lose it again, and if you need it, you can use it too.

And that’s one of the reasons people remember it as one of the more prominent of the 90s computer brands, even if they don’t usually remember it fondly.

What appliances should a landlord provide

What appliances should a landlord provide? Every landlord has a different opinion. I tend to be fairly generous. I’ll explain what I provide and why.

First, let me give you a hint: Often you have to spend money to make money, and a fully-stocked house can easily net you $20 additional in rent every month. Assuming a 10-year service life, that means you can afford to spend $700, and $700 buys a lot of used appliances. Also, if a tenant stays an extra year and your house isn’t vacant for a month while you’re getting a new tenant, that’s worth a few hundred dollars alone. Here are some tips on saving money on appliances if you need them.

Second: This isn’t what a landlord is required to provide. It’s what I recommend they provide based on my own experience.

Can’t connect to this network? Here’s the fix.

After upgrading to Windows 10, when I unhibernated my laptop the next morning, my wifi connection didn’t work. The connection dropped and I couldn’t reconnect. Forgetting the network and reconnecting didn’t help. Any time I tried to reconnect to my wireless network, I’d get the message that Windows 10 can’t connect to this network.

The problem seemed to be in the power management.
