Memento Mori

I've been reading and coding my way through the book "Black Hat Python" by Justin Seitz and really enjoying it. I'm only about halfway through it s far, but I've enjoyed it so much I wanted to share my experience so far. csuttles/ctlfish Tooling and dev doodles related to my activities on hackthebox.eu and other ethical hacking endeavors. - csuttles/ctlfish csuttles GitHub You can find the code corresponding to this post in the 'net' directory of this repo Checkpoint - Where am I now?

Overview During troubleshooting, you might find it useful to determine what is happening on the wire. While tcpdump is a great tool for capturing packets, it's does not offer the same level of filtering capability as tshark. While it may be easier to simply copy a capture file locally and use wireshark, sometimes restrictions prevent this approach. Capture and Save with tcpdump Capturing and saving to disk is my favorite way to review wire traffic.

I'm writing an API client in golang, and while testing the API with curl, my results were reasonable (0.8 seconds REAL time), but when I got my API client working in golang with resty, I found that my response time was very slow (over 75 seconds). This is a true (and ugly) story about figuring out what was wrong and resolving the issue.Here's my boilerplate resty code: resty.SetDebug(true) resty.SetTLSClientConfig(&tls.Config{ InsecureSkipVerify: true }) resp, err := resty.

IPv4 and IPv6 This post will explore key differences between IPv4 and IPv6. IPv4 has been around for a long time and is what moves data around the internet. IPv6 has also been around for many years at this point, but is finally seeing adoption now that IPv4 addresses are nearly exhausted world wide. There are many papers and posts discussing why adoption of IPv6 is important, so I will instead focus on the technical details and leave the reader to make their own evaluation of the merits of IPv6 adoption.
