[amsat-bb] APRS and Tracking Software for Linux?

Hopefully someone can help me here.

I am experimenting with Ubuntu Linux 6.06 LTS here...and I'm so far impressed with the speed and ease of use. It's certainly no Windows XP, but it's not bad.

So...what are other Linux users using for APRS duty? Soundcard packet/APRS? Tracking?

No hurry...since I'm not swtiching my 333 MHz Celeron. I'm just in the "learning curve".
