I'm trying (without many success) to optimize my DSL connection. My
principal interest is allowing me to connect from an external machine
with ssh and vnc thru ssh. I also want to allow 3 internal computers to
connect from 192.168.0.2-4 and browse the web, etc.
However, once mldonkey is started all the connections seem to go to a
crawl. This is my preliminary script, modified from wondershaper and
some mldonkey-specific script:
IPTCMD="iptables -A WSHAPER -t mangle -p"
tc disc del dev $DEV root 2> /dev/null > /dev/null
tc disc del dev $DEV ingress 2> /dev/null > /dev/null
iptables -t mangle -D POSTROUTING -o $DEV -j WSHAPER 2> /dev/null
\
> /dev/null
ip link set dev $DEV qlen $QLEN
tc qdisc add dev $DEV root handle 1: htb r2q $RQ default 13
tc class add dev $DEV parent 1: classid 1:1 htb rate
