I just ran into this issue when adding a Google cloud auth key via the command line threw out an error about the JWT token being invalid, even though it was just created. The command I was running was: gcloud auth activate-service-account --key-file auth.json The error I was receiving was: ERROR: (gcloud.auth.activate-service-account) There was a problem refreshing your current auth tokens: ('invalid_grant: Invalid JWT: Token must be a short-lived token (60 minutes) and in a reasonable timeframe.

I'm afraid I've been very busy lately with a new job working overnights and figuring out all my college needs for moving in next month, but I've been doing a lot of research and reading on a few interesting topics so hopefully the next few posts will be very interesting. I've also updated a few of my posts including my wifi sniffing and securing your home network posts, so check those out! Today's post is about one of the most important netsec tools you will have in your arsenal. This program is called Nmap and is a free, open-source network auditing and security tool that we will use quite often while looking for vulnerabilities on networks. I will be explaining how to install and do some basic usage on Linux AND Windows (yay Windows!). I will be using my Backtrack 5 for Linux and Windows XP and hopefully get a Vista/Win7 part up as well.
