Finding a URL For File Transfer Cmdlets
I just posted a blog about our new File Transfer Cmdlets in which I artfully dodged a difficult question: How do you get the URL to do the file transfer? Sometimes you are going to have it but other times you’ll go to a website and it can be bloody impossible to find the URL that you need to download. That was the case with the example I used. Let me provide it. Navigate HERE and tell me if you can find the URLs to download the kits? (If you find out how – let me know – I’d REALLY appreciate it.)
My new motto is Experiment, Enjoy, Engage (which means share). Luckily, we have a great community of people already doing this. One of them is Robbie Foust. Robbie recently wrote a Packet Sniffer For PowerShell. I picked it up over the holidays and thought it was wicked cool but I wasn’t sure when I would use it. Well…. I didn’t have to wait to long for that question to be answered.
Here is how I got the URL for to transfer the file. I downloaded Robbie’s script from HERE. I ran Get-Packet and it went displayed everything and caused a beep-storm on my PC. I thought about a minute and came up with the one-liner below. I navigated to the download page in my browser, ran the one-liner, clicked the download button, captured the packet, hit ESC to stop Get-packet and then stopped the file transfer. Here is what it looked like:
PS> Get-Packet |where {$_.data -match “download”}
Using IPv4 Address: 192.168.1.195
Press ESC to stop the packet sniffer …
