tcng version 10b
I''m just learning about htb and using tcng. I am trying to make the
example in
Martin A. Brown''s Traffic Control with tcng and HTB HOWTO v0.5
example 2
/*
* Simply commented example of a tcng traffic control file.
*
* Martin A. Brown <mabrown@securepipe.com>
*
* Example: Using class selection path.
*
* (If you are reading the processed output in HTML, the callouts are
* clickable links to the description text.)
*
*/
#include "fields.tc"
#include "ports.tc"
#define INTERFACE eth0
dev INTERFACE {
egress {
/* In class selection path, the filters come first! DSmark */
class ( <$ssh> ) if tcp_sport == 22 && ip_tos_delay ==
1 ;
class ( <$audio> ) if tcp_sport == 554 || tcp_dport == 7070 ;
class ( <$bulk> ) \
if tcp_sport == PORT_SSH || tcp_dport == PORT_HTTP ;
class ( <$other> ) if 1 ;
/* section in which we configure the qdiscs and classes */
htb () {
class ( rate 600kbps, ceil 600kbps ) {
$ssh = class ( rate 64kbps, ceil 128kbps ) { sfq; } ;
$audio = class ( rate 128kbps, ceil 128kbps ) { sfq; } ;
$bulk = class ( rate 256kbps, ceil 512kbps ) { sfq; } ;
$other = class ( rate 128kbps, ceil 384kbps ) { sfq; } ;
}
}
}
}
The results indicate an error which does not mean much to me. Could
someone explain what I might have done wrong.

please
try to reorder matches)
