...vpn to do the job. So I picked up tinc's source code for the first time, got it working on IPv6 as a switch in a matter of minutes between two endpoints (very impressed, thx!), and started hacking at it to see where I would get. This is partially the outgrowth of looking at an ietf document on ecn encapsulation and vpns.... https://tools.ietf.org/html/rfc6040 Experimental patches so far are at: https://github.com/dtaht/tinc I successfully converted tinc to use sendmsg and recvmsg, acquire (at least on linux) the TTL/Hoplimit and IP_TOS/IPv6_TCLASS packet fields, as well as SO_TIMESTAMPNS...

Dear Community, sorry for the somewhat dumb question. Maybe someone has any pointer to how to setup the RED queue to mark pakets with ECN. In particular what are appropriate parameter settings for limit, min, max, etc. All my trials end up with either "RTNETLINK answers: Invalid argument", although the command line (at least for me) looks fine in regard to what is said on the man page. "tc qdisc replace dev lo...

...ot; flow control in the form of RELAY_SENDME cells, but given that multiple circuits can end up being multiplexed over a singlular TCP/IP connection, propagation of these RELAY_SENDME cells can get delayed due to HOL issues. So, with that quick and dirty overview out of the way: * "Ah so if ecn is enabled it can be used?" ECN will be used if it is enabled, *but* the congestion information will not get propaged to the source/destination of a given stream. * "Does it retain iw10 (the Linux default nowadays sadly)?" Each TCP/IP connection if sent from a host that...

I have a Cable ''modem'' that has a problem that many of these devices is bound to have. I was wondering what other lartc user thought about this and if DSL has simular problems. Cable, being Asymetrical, is able to upload at a given rate and hopefully has a buffer, in the modem, of some kind. When I nc(netcat) to a UDP echo, or discard, server I get about 10Mbps out on my

To test the new ECN Shorewall 1.4 feature that I announced recently, I have enabled ECN on my firewall and on my mail/list server. I''ve collected a list of IP addresses that were timing out on email delivery and put them in my /etc/shorewall/ecn file. One user emailed me this morning to say that his versi...

Hello, I have been using shorewall for a long time now. I find it a great piece of software and I am looking forward to the IPv6 version that Tom is planning to start working on. I do however have a problem now that I do not seem to be able to solve. On my firewall system I have a Fedora Core 2 installation with Shorewall (2.0.13) running fine with kernel 2.6.6-1.435.2.3. When I however use a new

I''ve decided to make a late addition to 1.4.0. A number of you have encountered a problem whereby TCP connections could not be established to certain sites. The solution was to turn of Explicit Congestion Notification (ECN -- RFC 3168). I have added a facility whereby ECN may be turned off on a host or network basis. A new /etc/shorewall/ecn file (format is the same as /etc/shorewall/routestopped) defines the sites for which ECN is to be disabled. To use the new facility: a) You must be running kernel 2.4.20....
