similar to: tc and HTB

Hi there, I am trying to understand our router / firewall, that was configured by another person. It is a Debian GNU/Linux with several configurations with tc and iptables. I have a question about flowid in ingress qdisc. As fas as I know, this qdisc is a dummy one, and flowid is just used with :1 because the traffic have to be redirected to something. However, in our router, there are some

Dear all, I''m having real problems getting tc to do anything useful at all. I''m also under pressure to get this fixed before the students start arriving later this month (I work in a university). In short, I want each IP address to be hard limited to 128kbit down, 64kbit up, never to be allowed more bandwidth than this. It is also important that the latency remains

Hi! I am learning tcng without having experiance of tc and I am trying to build something that shall schedule traffic dependent on the value in the IPv4 packets ip_ttl field. I have read the tcng reference manual and cannot find information about forwarding. Is it possible to farward packets from ingress to egress without sending them upwards in layers?

Hi ! I wanted to shape my analog modem connection so I took these two lines from the ''wondershaper'' script: tc qdisc add dev $DEV handle ffff: ingress #tc filter add dev $DEV parent ffff: protocol ip prio 50 u32 match ip \ src 0.0.0.0/0 police rate ${DOWNLINK} burst 10k drop flowid :1 with DEV=ppp0 and DOWNLINK=24kbit. But, when I activate it, nothing comes back from the

I am currently using the ultimate-tc script from http://lartc.org/howto/lartc.cookbook.ultimate-tc.html and I want to make sure that internet radio packets (mp3 streaming audio) will always get through no matter what. I have added some iptables commands like this: iptables -A OUTPUT -t mangle -p tcp --dport 8000 -j TOS --set-tos Minimize-Delay iptables -A OUTPUT -t mangle -p tcp --sport 8000 -j

[I sent this earlier but I guess the list is subscriber-only?] I just set up wondershaper, it has a simple filter on the downstream direction to limit the bandwidth usage: tc qdisc add dev $DEV handle ffff: ingress tc filter add dev $DEV parent ffff: protocol ip prio 50 u32 match ip src \ 0.0.0.0/0 police rate ${DOWNLINK}kbit burst 10k drop flowid :1 This is effective but is there any way to

Hi, all I''ve got problems with tc qdisc ingress. I''m using vanillia kernel 2.6.14.4 patched with http://www.ssi.bg/~ja/routes-2.6.14-12.diff, and iproute2-2.6.14-051107. i am using ingress to limit incoming traffic : (DEV is eth1 / DOWNLINK is 7700) # attach ingress policer: tc qdisc add dev $DEV handle ffff: ingress # filter *everything* to it (0.0.0.0/0), drop everything

Hi all I have a trouble configuring the qdiscs, when I indicate the "perturb 10" option to tc, i gives me this error: tc qdisc add dev eth0 parent 5:1323 handle 1323 sfq perturb 10 RTNETLINK answers: Invalid argument if I don''t put the "perturb 10" option, it works. another question is about iptables, when I indicate the " --set-mark" option: iptables -t

Dear list, I want to rate-limit a couple of customers in both up and down directions. They get a different speed for traffic staying on our network than for traffic towards/from the internet, so that''s a master class and 2 child classes per customer per interface. I made a test setup with cbq which worked, but wasn''t too reliable I measured a tolerance of about 30%. I read

Hi, I am trying to do both ingress and egress bandwidth management on a bridge. eth0 is the WAN interface. IPTraf shows that the following script is running successfully and it limits bandwidth both ways to 256 KB However when I want to see the statistics using tc - it only shows me stats for htb class and not for ingress class. The tc output is as follows: tc -s -d class show dev eth0 class

I''m trying to setup traffic shaping on my linux gateway/router. The system has 3 interfaces: eth0 - My LAN - with IP address 192.168.0.254 eth1 - The ethernet connection to which my ADSL modem is connected. This has a 10.25.x.x IP, more on this later. The ADSL link has an upstream of ~1.2mbit. ppp0 - The PPP connection which is my WAN connection, with a real world IP. The system acts

Hi all, this is really not really very easy to understand, or, to get in. Well, I''ve the following configuration on the router box: LAN - interface: eth0 - network: 192.168.2.5/24 - bandwidth: 100Mbit/s INET interface - interface: ppp0 - network: .dynamic.ip./0 - bandwidth: DOWN=1536kbit/s and UP=256kbit/s the LAN interface is to serve 6 other clients with internet and

Hi all, Another requirement we have is that traffic entering the DS domain be classified then subsequently assigned a (different?) DSCP based upon its classification. For illustrative purposes only let''s say (for traffic entering the DS domain on dev eth0): - WWW traffic would be marked BE - traffic destined for 10.10.10.10 would be marked AF11 - VoIP traffic from 20.20.20.20 would

Hello, I run one of my PCs as my personal router, with iptables+tc to control traffic and be my firewall. In TC, I use a combination of htb, qdisc and sfq (as well as prio) to classify bandwidth. In my current setup, I have 10 classifications of my bandwidth. (Even I admit this is probably more than I need, but at this point I''m still learning, so I''ll just leave them be.)

Hi there, I have a Samba installation acting as a Domain Member with a disk share (the partiton is mounted with acl and user_xattr options). I am not using winbind, because I want the domain users to be mapped to Unix users. Everything works right, excepting the users in the Windows Explorer security tab. I will try to explain the situation with an example. I have username map, that maps

Hi, Has anyone used TC in a wireless environment, which is dynamic. I understand that the parameters for queuing are static and cannot be changed unless the queuing discipline is deleted and reloaded with different parameters. If anyone can share any experience, that would be helpful. Thanx. Azim. _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl

I''m trying to shape traffic on a Devil-Linux box. This note was originally sent to their maillist, because the LARTC list appears to have been down for the past few days. My mailbox was just flooded with a half dozen or so confirmation requests in response to my repeated attempts to subscribe to this list. ---------- Forwarded message ---------- From: drew einhorn

Hello everyone: As it is known, when you limit uplink bandwidth it usually gets downlink bandwidth to a lower value. I just want to know what is the optimal configuration for eth1 and imq0 according to some variables of tc(HTB), txqueuelen, mtu, etc. to make these packet flows less independent on an ethernet based network. Thank you in advance. -Diego

Hi there good people, I''m a newbie in what concerns running Linux on machines other than desktops, so I need help from all you gurus out there :-) I have Linux installed on an old computer (Winchip C6, Pentium clone), acting as a router/firewall for two other computers. Both these machines are connected to the firewall via a dedicated ethernet card each, on different subnets,

Hi everyone, I''m new to tc but I need to use it to set up shaping on a new NAT box. In short: Each user must have their upload limited to 128kbit and downlink limited to 256kbit. Global bandwidth to be limited to 100Mbit Interactive packets to have higher priority 200+ users, so need to match packets fast So far I have managed to get the download limits working. However I need to
