htb-gen Description

htb-gen is an easy, scalable bandwidth management tool. htb-gen is meant to be an easy, scalable, yet powerfull, bandwidth management tool. You can set up/down portions of bandwith for each host or network, that goes trough your firewall/router.Prioritary traffic(web, mail, gaming, ftp, voip, streaming) is preferred over Junk traffic(kazaa, emule, etc). Also dynamic bandwith borrow and re-assignation is done betwen host thanks to htb boundaries.A web-frontend for config is avaible as well, so remote management is possible. All bash based so it can be used in embedded routers/firewalls (wired/wireless).Two backend are aviable:· generates raw tc commands · generates htb-init conf files (util for integration)The packet clasification is done by iptablesRequirements:· bash· QoS htb kernel support· iproute2 tc· iptables· htb-init script (optional)How does it workThe bw that you assign for each host is divided like this (this can be easy addapted if you know a litle bit of iptables):Prio traffic· packets smallest than 100bytes (tcp ACKs, most icmp messages) · all icmp traffic (icmp messages) · all udp traffic (voip, streaming, real time gaiming, etc...) · some tcp ports (seteable in conf file, ie: http,pop3,imap,ssh...)Default traffic (junk traffic)· all traffic that do not mach any of the above (ie:emule, torrent, kazaa, gnutella...and so on)By thefault the host bandwidth is shared betwen this two kind of traffic, but the script grants that anytime that i use "prio traffic" it will climb up to 90%, till that 'prio traffic' ends. This % can be modified if you want, see the 'rate_dfl_percet' value in conf. Also is posible to save junk bandwith assigning only a % of host ceil to the dfl traffic, see 'ceil_dfl_percet'. This will help to have several host sharing bw without almost any complaint.What's New in This Release:· Multiple network interfaces are supported, so you can now have multiple LANs and multiple ISPs.· Per-host P2P percent of rate assignation is supported.· tc batch mode is supported, so now both iptables and tc are batched.· For each client, you can define prio_tcp_ports, prio_udp_ports, prio_protos, and prio_helpers (netfilter helpers).· A half-coded PHP-based Web front-end was built with PEAR Quick Form.
