...to configure this algoritm properly. Maybe somone can help me and write a little example for me (the best will be Patrick McHardy who has ported HFSC to linux) - please just three queues. My situation: Let say I have 1Mbit of bandwidth. I need three queues: - prio queue (with low delays, and 100 kbit guaranted rate ) - 1_client queue (with 0 kbit guaranted rate and fairness share the unsued rest of bandwidth) - 2_client queue (with 0 kbit guaranted rate and fairness share the unsued rest of bandwidth) Here you can field the queues configuration: tc qdisc add dev imq0 root handle 1:0 hfsc defa...

Hi, We have a 256 kbits/s (kilobits per second) link to the internet. it is a router running Linux that belongs to our ISP. They have given us 8 internet ips. (i.e- subnet is 255.255.255.248). one has been given to this router. I have given another internet ip to the firewall running CentOS 4.5. iptables is running on i...

...I have given many SNAT rules per ip basic. some users have full access, some have only web and smtp. I have added many forward rules to suit those SNAT rules. All work fine. one LAN is 192.168.100.0/24, while the other LAN is 192.168.101.0/24 Now, I want LAN with 192.168.101.0/24 to allocate 64 kbit out of 256 kbit. the rest for others. I added rules to the firewall. But I still can not allocate 64 kbit for LAN with 192.168.101.0/24 I think I need a PREROUTING chain for LAN with 192.168.101.0/24 Script is given below.

This makes 50 frames per sec. modes bit-rate 8 kbit/s (narrowband mode 3) = 20 bytes per frame 11 kbit/s (narrowband mode 4) = 28 bytes per frame 15 kbit/s (narrowband mode 5) = 38 bytes per frame 18,2 kbit/s (narrowband mode 6) = 46 bytes per frame 24,6 kbit/s (narrowband mode 7) = 62 bytes per frame And for VBR frame size is from a...

Hi. I am trying to shape my upstream bandwidth, mostly per port. and I am having some problems getting things to work the way I want them to. before I throw my configuration at you guys ;), I`d like to debug it by myself - but I was not able to find a tool that allow me to monitor current bandwidth usage per port (and preferably even per port+ip). I want to know what is the current bandwidth

Hi all, I''ve got a BOX running CentOS 4.5. It acts as a firewall + router. I have installed both iptables and iproute2. I has 3 network cards. eth0 is connected to Internet (is has an internet ip. pls assume its ip is 1.2.3.4/29). it is a 256 Kbit link. eth1 is DMZ. its ip is 192.168.100.254 eth2 is LAN. Its ip is 192.168.101.254 I have alreday shaped traffic to 64 Kbit on eth1 for downloadig (i.e DMZ zone ). This is the sript that does the job. It works ine. #traffic shaping on eth1 (Downloading) INTERFAZ_DMZ=eth1 FULLBANDWIDTH=256 BAND...
