[KLUG Members] Poor internet performance from Linux/Unix clients

[Goron, Chris]

Satelite is my last choice as well for high speed internet but it's also
my only choice right now. I wanted satelite tv and the broadband
internet was not a huge investment by any means at that time and
honestly and really seems to work well for me (in Windows anyway),
latency has never seemed to be a problem.

There is a company that sells a Linux/Unix satelite receiver package (I
forget the name) but it's rather expensive (more than the whole system
cost me) and I have never found any Open Source options available on the
web. DirecPC only supports Windows and I'm not sure if any of the newer
ones support anything else as well.

The MTU/MRU are the settings that came to me as well and that's what i
was kind of hoping someone might have some settings to try. I haven't
got a clue and DirecPC I'm sure would be no help.

Okay, I'm not going to be much help.  Starband is a two way satellite
and the only research I did on the older download only receivers was
a few minutes, long enough to figure out I didn't want that at all.
(I'm also resisting the two way receivers for different reasons)

Is there anyway to get the Win2K box completely out of the picture
and only use Linux?  Or is the receiver card windows only drivers?

The only thing that comes to my mind, is to try and find out what
the MTU/MRU settings that the satellite uses, and set the Linux
ethernet interface to those values.  (guess, and a long shot)
