    válasz mgrincs #7638 üzenetére

    Megnéztem a script generátort. Ügyes.
    A step3-ban van egy háromszöges felkiáltójeles opció a nyilak között (Advanced options) ahol a "generate bandwidth management script using dev" kapcsoló található.
    Ezt bekacsolva minden interface megvan (br0, eth0, eth1, eth2, vlan0, vlan1, ppp0) ami WiFi routerekben szokás, tehát nemcsak a belső háló.

    Másképpen nézve a script generátor által generált script minden routeren simán jó lehet ha tudod mi az interfacek neve.

    Mondjuk ha valakit komolyabban érdekel a traffic control lelkivilága még mindig érdemes lehet megnézni a linkekeket amit a korábbi hsz-ban megadtam. A generátort ill. a leírásokat nézve könnyen meg lehet érteni mi történik ill. sokat lehet tanulni belőlük.

    Alternatíva lehet még a kész wshaper script használata (nem tudom milyen firm. alatt van ezen a routeren). Ez helyből tud alacsony forrás/cél portot és IP címet kezelni (ha ennyi elég).
    lartc wshaper.

    Paraméterek:
    # $1: wshaper command (start, stop, status)
    # $2: WAN interface name (`nvram get wan_ifname` on Oleg)
    # $3: DL kbit/sec
    # $4: UL kbit/sec
    # $5: low pri src IP or " " for empty
    # $6: low pri dst IP or " " for empty
    # $7: low pri src port
    # $8: low pri dst port

    Azaz pl.
    /wshaper path/wshaper start <WAN IF neve> <DL speed> <UL speed> <alacsony pri. forrás IP> <alacsony pri. cél IP> " " " "

    A script WL500/Oleg-ből (jól látszanak a tc parancsok):

    # Wonder Shaper

    # low priority source ports
