Hi all, Does anybody know a package to control the bandwidth using "TCP Congestion Control" method? Best Regards Hoomaan Naimi Afranet Network Administrator

Hi, I would like to control download bandwidth from the Internet for clients inside a network. The gateway is a Linux box using ''iptables nat''. I would like to use ''iptables mangle'' to mark the packets coming from the Internet and going to specific clients and then use CBQ to shape it: +-----------+ Internal network | Linux

Hello, My company runs several Internet Cafes in Mexico, where bandwith is limited and very costly. We use Linux to do NAT and firewall stuff and at each location we have about 30-40 stations. I''d like to know if anyone out there has any suggestions about how to use CBQ to limit the bandwith at each station. We only have a 128k circuit. The problem I am having is that since I have that

Hi, in FreeBSD kernel is options that make router stealth, packet passed throw router have no change in TTL value. Is a posibility to make similar thing in Linux, I think that in traceroute isn''t this hop, no asteris, no router, no change in TTL, nothing ...? PSIkappa psi@atlantis.sk

Hello, it seems, that filtering on nexthdr (TCP/UDP) content, especially src or dst port, is not working. The following has no effect on 2.4.16 or older (even 2.2) kernels: # tc filter add dev eth0 parent ffff: protocol ip prio 50 u32 match tcp dst 3128 0xffff police rate 40kbit burst 10k drop flowid :1 Even if # tc filter ls dev eth0 parent ffff: filter protocol ip pref 50 u32 filter protocol

Hi there, I have two ethernet connections of 2Mbit/s each and I''m trying to add them together to one 4Mbit/s connection but I cannot get more than approximate 1Mbit/s! My setup: I have a LAN (10.2.18.0/24), connected to a larger network (10.0.0.0/8) by two WAN-connections with 2Mbit/s each. On each end I have a Linux router. I first setup the routers to use TEQL with one of the
