zdielanie netu

Vsetko je o studiu :)

Doporucujem nastudovat IPTABLES, HTB, IMQ ak mas delit pasmo pre IP-cky za NATOM

nie je to tazke, ked to pochopis.

pritom sa naucis patch iptables aj kernel (aj kompilovat)

IMQ patch
http://www.linuximq.net/

IPTABLES
http://www.netfilter.org/

a potom to vyzera tak nejako

INET_IFACE="eth0"

MAX_LINKA="2"

TC="/sbin/tc"

#Mazem nastavenia shapera na interface
$TC qdisc del dev imq0 root

$TC qdisc add dev imq0 root handle 1: htb default 10 r2q 2

$TC class add dev imq0 parent 1: classid 1:1 htb rate ${MAX_LINKA}mbit ceil ${MAX_LINKA}mbit


########## Upload + Download je rovnaky tak mozem vyuzit jedno imq ##########

/sbin/tc class add dev imq0 parent 1:1 classid 1:4 htb rate 51kbit ceil 51kbit

/sbin/tc filter add dev imq0 parent 1: protocol ip prio 1 u32 match ip src 10.0.0.11 flowid 1:3

/sbin/tc filter add dev imq0 parent 1: protocol ip prio 1 u32 match ip dst 10.0.0.11 flowid 1:3

/sbin/tc qdisc add dev imq0 parent 1:4 handle 4:0 sfq perturb 10


#Pravidla pre iptables

/sbin/iptables -t mangle -A POSTROUTING -o $INET_IFACE -j IMQ --todev 0

/sbin/iptables -t mangle -A PREROUTING -i $INET_IFACE -j IMQ --todev 0


keby si chcel mat rozdielny Upload a Downloas tak to vyzera takto
INET_IFACE="eth0"

MAX_LINKA="2"

TC="/sbin/tc"

#Mazem nastavenia shapera na interface
$TC qdisc del dev imq0 root

$TC qdisc del dev imq1 root

$TC qdisc add dev imq0 root handle 1: htb default 10 r2q 2

$TC class add dev imq0 parent 1: classid 1:1 htb rate ${MAX_LINKA}mbit ceil ${MAX_LINKA}mbit

$TC qdisc add dev imq1 root handle 1: htb default 10 r2q 2

$TC class add dev imq1 parent 1: classid 1:1 htb rate ${MAX_LINKA}mbit ceil ${MAX_LINKA}mbit

Tak to je zhruba vsetko :), tvorivosti sa medze nekladu :)

Viacej vid. man :)
