Ingress question with sub classes
Hi,
I wanted to configure the following :
1. VPN + some other special connections (TCP 82,8282,23,22 and ICMP) to
have priority over the rest
2. special upstream for our updating system on port 4000
3. within the VPN tunnels citrix traffic ( TCP 1494, 2598) + icmp has
priority
I need this for both incoming and outgoing traffic as it is the bandwith

Need some help
Hi all, I have read the larc howto and I need to apply a traffic shaper
with this configuration:
router / two interface etho and eth1
lan
lan is on eth1 and on eth0 I''ve the dsl connection (1.2 Mbit / 256 kbit)
I need to limit the bandwith towards lan and I''ve thought at HTB and
tcng. I write the script belove. I want limit the p2p and ftp (ssh and

TCNG question
Hey all, i have a class.

Now when i apply this traffic TO 6 on port 22 is indeed limited to the speed
i specify BUT it doesn''t seem to take the src into account at all. If i

tcng and ip_len
I can''t seem to match packets less than 512 bytes:
class( <$bulk> )
if tcp_dport == 81 && !( ip_len & 0xfe00 )
;
or
if tcp_dport == 81 && ip_len < 512
Both rules match any packet I send to port 81, even when the total IP length
is much greater than 512 bytes:

PRIO and TBF is much better than HTB??
Hello mailing list,
i stand bevor a mystery and cannot explain it J. I want to do shaping and
prioritization and I have done these following configurations and
simulations. I can´t explain, that the combination of PRIO and TBF is much
better than the HTB (with the prio parameter) alone or in combination with
the SFQ.
Here are my example configurations: 2 Traffic Classes http (80 = 0x50) and

Hierarchy of HTBs
I''ve been having a bit of difficulty with a hierarchy of HTBs that I''m
wanting to create. Essentially, I''ve got one interface that goes to both
the DMZ and the internet. When going to the internet, some of the traffic
will be going through a VPN and therefore I want to prioritize it
differently, however I want to give the DMZ traffic full speed as long as

Newbie STILL trying to limit bandwidth - is this script wrong?
My previous message

how to define a port range?
hi,
i´am new in tcc (tcng). i try to define my qos for VoIP-Services.
For this i wantto define a class for a port range 10000 till 15000.
how is the right way?
this down works:
class (<$voip>) if tcp_sport => 10000 || tcp_sport <= 10000 ;
are there any examples of real installations - maybe including VoIP,
HTTP and P2P services?

Absolute Maximal Bandwidth
Hey,
I currently have a box serving as a firewall (running iptables) and packet
shaper (using tc / tcng''s tcc compiler) to shape a large amount of inbound
and outbound traffic to my data center.
Whilst I can perform shaping functions using HTB, I need to also provide an
absolute (to the nearest few 100kb/s) bandwidth usage maximum. As an example
I might have 200MBit/sec

Ingress and polishing
Hi,
We are using kernel 2.4.24, tcng version 10b.
I''m trying to do some policing in the ingress queue of the internet
device. Until now we had configured some filters dividing traffic into
queues, and on these queues the Double Leaky bucket meter was applied.
The idea is to have a minimum of bandwidth assigned per class (the cir
values) and a maximum (pir values), just as with the

simulating RED using tcsim question
I''m trying to setup a bottlekneck scenario so I can see the effects of
the RED qdisc on a congested interface.
My example simulation code is at the bottom of this email if someone
wants to see it.

TCNG Port Range
I''d like to set up a filter based on a port range.
I tried something like
class( <$test> )
if tcp_sport > 2001 && tcp_sport < 2015
;
But it seems to ''hang'' with this in there..
Is this the best/right way to go about this? if not, what is the best way?
Thanks

Simple HTB setup with tcng
Hello all,
I am trying to set up a simple htb based system, where packets with
source ip 10.0.0.1 should have their own class.
I plan to use tcng to set it up easier.
Is there something wrong in my tcng file ?
