Do machine accounts have to be group 100
...ations.
The adduser script is working and I can join machines to the domain 'on the
fly'
My question is; what are the implications of changing the group id of the
workstation machine accounts to a value other than 100?
Thanks

asypow.noncent: how does it work?
I am trying to do power calculations for the proportional odds model using the asypow library.
The code
noncenta90b10<-asypow.noncent(theta.ha=a9010,info.mat=infomatrixa90b10,constraints=constrt)
returns
Error in max(..., na.rm = na.rm) : invalid "mode" of argument.
the various arguments I've used are:
a9010
[,1]
[1,] -1.7357568
[2,] -0.1928619
specifying the theta.ha array as a row not a column makes no difference

How do I remove printer drivers from print$
I have done a foolish thing and I would like help undoing it!
I have managed to add drivers for all of the printers on my Samba server,
using the "Add printer driver wizard."
They are in print$ (/usr/local/samba/printers/W32X86)
The ones for my Win95 and 98 clients are in /usr/local/samba/printers/WIN40
but they are Wrong!
I cannot use the "Server Properties" tab in the

__Very__ Low Bandwidth
I am using the script below to simulate a very low bandwidth connection.
I found that I could turn the bandwidth knob down to about 4kbit, but
below that I didn''t get any traffic through. I''ve had a look at this
generally, but couldn''t find an answer. It doesn''t even seem like the
first reply packet gets through. I have tried it with much bigger
buffers,
