That said, it only looks at its One of these days I'll get around to writing a userspace codel lib in pure C. Or someone else will. The C++ versions in ns2, ns3, and mahimahi are hard to read. My currently pretty elegant codel2.h might be a starting point, if only I could solve count increasing without bound sanely. > own buffers to determine when to drop packets, and those only come in...

I have long included tinc in the cerowrt project as a lighter weight, meshy alternative to conventional vpns. I sat down a few days ago to think about how to make vpn connections work better through fq_codel, and decided I should maybe hack on a 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 outgr...

I'm deploying a CentOS 7 box as a gateway and I'm trying to figure out how to set up traffic shaping. Historically I've used the Wondershaper script but apparently it's not deprecated in favor of superior queue management. I haven't yet found a packaged solution and I'm wondering what others do to configure this kind of thing. Apparently the new modules are available

Dear latex/R-Sweavers, Using the codel below, I can color text in individual cells for latex output. Is there a similar way to get a background shading? My attempts failed because I did not get the closing brace at the right place with Hmisc/latex. library(Hmisc) x <- as.data.frame(diag(rnorm(3),nrow=3)) cellTex <- matrix(rep(&q...

...ding it is easy (mostly done already), but there isn't a whole lot of point (aside from my research into what protocols can be carried end to end in the ipv6 era). * There MAY be some linux kernel work into a better virtual tunneling device coming up. * I am pretty hot on the "add fq and codel" to a vpn daemon idea, is anyone else interested in pursuing that with me? > Lance > > _______________________________________________ > tinc-devel mailing list > tinc-devel at tinc-vpn.org > http://www.tinc-vpn.org/cgi-bin/mailman/listinfo/tinc-devel -- Dave T?ht thtt...

I came across this on the Fedora devel list. I added /etc/sysctl.d/51-bufferbloat.conf containing the suggested line and it installs the new codel qdisc as desired. There's probably more knobs that might be useful to tweak but this makes a good start. More reading on the bufferbloat site suggests that the later "cake" module will be even better, but it requires a newer kernel than CentOS currently ships with. <https://lis...

...M yes. I wouldn't be surprised that other OSes adopt it, though. Given how slow other OSes are evolving, I would not hold my breath, and retain code paths that worked with them.

...So that multiple relays can use the same "password" file (or database). I'd love to help the community out with this as well, so it can be open sourced. Would anyone (or groups of people) be willing to take it on ? I was also thinking of putting this type of project on a site like CodeLance.com ; and getting some people to bid on development, and just pay the fee -- and get it done ! MySQL backend for all this would be great. Cheers, --Matador I am also Matador on the #icecast channel

With pleasure we announce the release of tinc version 1.1pre11. Here is a summary of the changes: * Added a "network" command to list or switch networks. * Switched to Ed25519 keys and the ChaCha-Poly1305 cipher for the new protocol. * AutoConnect is now a boolean option, when enabled tinc always tries to keep at least three meta-connections open. * The new protocol now
