Problem mit wshaper.htb

[mangel]

Moin !

Ich benutze das wshaper.htb script und habe paar Schwierigkeiten damit:

1. Wenn jemand was per zB Apache was von mir downloadet, geht meine
Downloadrate in die Knie

2. Ich muss Uplink=60 reinschreiben obwohl ich 128kbps uplink habe
(dsl), sonst macht der full speed upload und dann ich gar nix mehr
downloaden, wenn es auf 60 steht dann ist die uploadrate = 14-15kb/s

Weis jemand Rat?

Ausgabe von ppp auf tty1

[mangel]

Hi alle



Ich habe nen kleines Problem:



Wenn meine DSL Verbindung aufgebaut wird erscheint die
Ausgabe immer auf tty1, das nervt nen bisl

Ich habe DoD und die Verbindung
wird schon beim booten aufgebaut.



Weis jemand wie ich die Ausgabe auf tty10 richten kann? Wo kann
ich das ändern?
