Understanding High Latency using Wireshark

We have discussed high latency a bit in my previous HakTip, but I wanted to go into it with some more detail. As you look at packets in a Wireshark capture, you'll notice that with a normal connection, your transmission happens in under a second. Now if you look at a few packets with slow communication, they show up to be almost a second each. This would be called wire latency because of the slowness happening on the wire, not the source or destination.

easywall - Web interface for easy use of the IPTables firewall on Linux systems written in Python3.

Firewalls are becoming increasingly important in today’s world. Hackers and automated scripts are constantly trying to invade your system and use it for Bitcoin mining, botnets or other things. To prevent these attacks, you can use a firewall on your system. IPTables is the strongest firewall in Linux because it can filter packets in the kernel before they reach the application. Using IPTables is not very easy for Linux beginners. We have created easywall - the simple IPTables web interface . The focus of the software is on easy installation and use.
