openbsd tcpdump + wireshark

Posted 02-27-2013 at 10:50 AM by rocket357 (Musings on technology, philosophy, and life in the corporate world)

I'm taking a class in a few days to delve into some deeper packet analysis than I've done before, and the instructor is a wireshark fanatic. Wireshark can be compiled on OpenBSD, but it has a reputation for security issues. I need a way to capture with tcpdump (privileged) and decode with wireshark (unprivileged) in realtime. Simple enough:

visudo (add "my_user ALL=/usr/sbin/tcpdump")
Download and compile wireshark (http://www.cromwell-intl.com/unix/co...n-openbsd.html...

Make some apps (mainly KDE apps with text fields) start faster

Just create a folder "~/.compose-cache".

Or better yet, at least in a semi-philosophical level, have your startup script to create "/dev/shm/.compose-cache" every time, and just create it once, and a soft link to your home folder. No unnecessary access to your disk, writing to and reading from memory instead. Which is often assumed to be better for several cache-type usages, both for performance and (supposedly) for the lifespan of your hard disk*. Some people...

Cost of ownership.

I've noticed over the past week or two, a few of my friends have posted on social media sites regarding issues they're having with the operating system they're currently using. I'm sure when I detail what the problems are, it'll follow that the OS in question is obvious without me naming and shaming it. I thought I'd share in a bit of detail how I think migrating to Linux* might help.
