Flowtag FreeBSD port

July 14, 2008

I just finished up the FreeBSD port for Chris and Scholar’s flowtag. Flowtag is a neat tool for tagging network streams for collaboration and analysis. I’ve submitted the port to FreeBSD’s mailing list, so I’m hoping for upstream soon. In the meantime, you can download the port files on my miscellaneous page.

In other news, development on Hex 2.0 continues forward, we’re trying to get ports finished for inclusion in the ISO, (which is what spawns the flowtag porting), malware analysis took a backseat to sysadmin work due to a rather large project that just finished up. Hopefully I’ll have more time to post here soon, here’s what I’ve been working on:

– A simple C program to measure the index of coincidence of a file (for binary data instead of strings). This was going great until I tried it on a non-OSX OS, now I’m running into segfaults trying to get it to run on Linux (does read() behave differently or something?). I’ve also ported it to Windows (which works), but was a giant pain due to the fact that I don’t ever use Visual Studio.

– A binary file to hex string beautifier; basically, take binary data and print it in really nice strings for either a ruby or a C program. Why? Because I’m tired of manually formatting data for programs.

– A program to generate data with variable amounts of randomness (this is really used for work, but I might end up posting it here depending on whether I think it’s neat enough).

– Rewriting labview (our internal machine allocation management software). Okay, so Jon’s really doing most of the work, but that’s mostly because I don’t know how to do SQL “relations”, I’ll do more of the development soon enough.

– Biking to work. Yea, this isn’t technical, but I got a new bike so I’ve been trying to cut down on the commute, save gas, all that kind of stuff.

UPDATE: Just got an email the flowtag port has been committed, it should be showing up the next time you do a “cvsup” :)
