Hi,
<snip from script>
DOWNLINK=1450
UPLINK=180
DEV=eth0
</script>
for some reason it seems to be droping all the packets...
pings/http/ssh/etc...
Do you know if I need to do any sort of Packet Mangling (ie. number the
packets)?
I'm going to include the wondershaper script below:
===========================================================================
#!/bin/bash
# Wonder Shaper
# please read the README before filling out these values
#
# Set the following values to somewhat less than your actual download
# and uplink speed. In kilobits. Also set the device that is to be shaped.
DOWNLINK=1450
UPLINK=180
DEV=eth0
# low priority OUTGOING traffic - you can leave this blank if you want
# low priority source netmasks
NOPRIOHOSTSRC=80
# low priority destination netmasks
NOPRIOHOSTDST=
# low priority source ports
NOPRIOPORTSRC=
# low priority destination ports
NOPRIOPORTDST=
# Now remove the following two lines :-)
echo Please read the documentation in 'README' first :-\)
exit
