ClamAV client/server setup

Note: This may very well be well-known information, but I found it difficult to get exact answers from the official ClamAV documentation, available man pages, and other kinds of documentation. The most useful hint originated from a mailing list thread considering ClamAV version 0.70, which is getting rather outdated. My original issue was getting antivirus […]

Raspberry Pi controlled mousetrap

Having had a few spare moments this holiday, I’ve been contemplating how to monitor a mousetrap or two in the attic. By doing that I wouldn’t have to go up to the cold attic in vain, but empty and reset the mousetraps only when needed. It occurred to me that since I’ve already got a […]

Installing Bro, the network security monitor, on a Raspberry Pi

In the continuing quest to install security software on Raspberry Pis, testing their capacity to be used as small nodes that can be placed here and there on demand, the time has come for installing Bro. The hardware/OS in question is a Raspberry Pi 2, with 1G RAM and 4 CPU cores. It’s running the […]

Streaming pcap to a dummy interface

In an earlier article, I described how to stream captured network traffic to a remote host for IDS analysis with Snort. Mikrotik units can stream captured traffic elsewhere using the TaZmen Sniffer Protocol (TZSP). tcpdump and Wireshark natively decode this protocol, but unfortunately it doesn’t seem to be supported by any other of the large […]

Mobile entertainment center

Our three kids very seldom agree which TV program or movie to watch. Allowing for less discussion when screen time is granted, I’ve set up a mobile entertainment center where each kid may watch the movie of their choice – this may be used during long drives, on trains or buses, and everywhere else where […]

IDS with MikroTik and Snort

UPDATE: For more flexible streaming, and for not having to hack your Snort init scripts, you might want to consider this article as well. Now back to the scheduled program. Port mirroring on a strategically positioned switch can be the best setup for an IDS sensor. If that’s not an option, RouterOS-based MikroTik devices support […]

Streaming from an underwater camera with a Raspberry Pi

Among this summer’s projects was getting an underwater camera online and streaming. The camera is placed within a fishing device designed like a cage, called Kjærra, dating back to the 14th century. The trap has a one-way entry; the fish enters the cage and can’t escape, and is subsequently extracted from the cage. When the […]
