hashlimit implements a packet based token bucket filter, where as for traffic
shaping you want something bit based.
there is a hack way to archive this with hashlimit however.. if you setup rules
using the length module to group packets first by size then pass them through to
separate hashlimit rules each with the appropriate rate in packets for the size
of the expected packets you could attempt to achieve this goal however it would
be a hack and poor substitute for the power of tc and htb.
however with tc you setup classes for how you want bandwidth to be split up like
class1 - 100-200k
class2 - 20-200k
class3 - 20-100k
where we can say all voice goes over class1, subnet a goes over class2 and
subnet b goes over class 3
the only way 2 give individual machines their own limit is to setup individual
classes for them which inst practical
.. at least as far as i am aware and have used tc, somebody please correct me on
this as i too have longed for a solution to this problem.
