LS, Spent a lot of this weekend reading about shaping and traffic control. The Howto is very extensive... :-) I hope to use this list to see if what I want is possible. The situation: - A central (big) Citrix cluster located in Frankfurt (all servers in one subnet) - The office in Rotterdam connected to Franfurt with a 2Mbit line - The office in Bergen (Norway) connected to *Rotterdam* with a 128 line Normal citrix session uses max 20k/s, printing is not limited! The problem is obvious, one user sent a big print job... Away is the interactive performance.. What i'm thinking of: [Citrix cluster] -- [Linux proxy-arp shaper]-- Router to RTD -- Router to Brg What is probably very easy to do is bring all the printers in a separate subnet in Bergen and use iptables to mark the packets for this subnet (I build a proxy-arp firewall before, so these are familiair techniques). It seems that Citrix traffic uses dynamic port numbers so identifying them this way seems impossible. If someone knows a way to use the u32 filter to select Citrix normal and Citrix printing traffic??? The behaviour that I would like to get: - If no other traffic, printing or interactive get 100% - If other traffic, printing gets the rest I don't know if this is possible, acceptable would also be, let printing never exceed 30% of the total bandwidth Thank you very much for your help!
