[a <aandrews@mediswitch.co.za>]

g'day
i want to add remote users.i have experimented with users in the (/spool)/fax/etc -hosts file with zero joy.
question 1:- are the field separator's full colons or pipes? does this matter ??
question 2:- setting an admin password???
i have tried a host file to the form
machinename:userid:passwd:admin passwd with various field separators without succees
