-
- I have two 386BSD systems networked, and here's what I do...
-
- One system is a 386SX-25 with 8 MB RAM, 85 MB disk, and SVGA. It is
- my general workstation, running a small DOS partition (for an occassional
- game or word processing session), minimal 386BSD partition, and (RSN)
- a small Linux partition.
-
- The other system is a 386DX-33 with 8 MB RAM, 200 MB disk, and monochrome.
- This system has a single 386BSD partition that contains the complete
- system, including X.
-
- I use NFS so the SX can access the X programs. I also start a remote
- xterm session so I can do stuff on the DX (like compiling). I don't
- have a lot of NFS activity because I only need to load a few apps, so
- the DX is just sitting there begging for work. I tried running other remote
- X apps, but network activity slows things down too much. Interactive
- apps (such as a remote xterm) are OK, but display-intensive applications
- are best run on the local X system.
-
- All that said, it is practical to have a file server and several
- X servers connected via NFS. I don't know what the limit would be,
- maybe the Ethernet maximum of 30 if everybody didn't start X at the
- same time, but it is a very cheap setup. Considering the requirements
- of Linux, it would be even cheaper than 386BSD because you can get by
- with 20-25 MB of disk space (rather than 45 MB) on the X servers.
-
- Distributed processing is a broad topic and X is really a weak example
- when you consider that network traffic bogs the machine down when
- running display-intensive apps. I realize I swayed from the topic
- when I described my setup, but I wanted to present it as an example
- of usefulness. I'm interested in reading about other useful client-server
- (or other forms of distributed processing) applications involving
- free operating systems so we can make the most of our computers. Anybody
- have some interesting applications or ideas they would like to share with
- us?
