Hello from Guifi.net - Catalonia. People from a rural hacklab in Itatiaia (Brasil)[1] are going to suporpt a intensive project for start to develop a free, open and neutral network in rural areas in Brasil. 1st part of project start September 5th until 20th. We're going to research social, economical and technological reality in rural areas in Brasil, to make some links in this area and to develop free software for their needs. Of course I was thinking to do it with Libre-Mesh in cheap routers and I hope some of you find this project interesting to come to work on it together. They pay travels, food and host for a little team (3-4 people). I can not to decide who (they do it), but they tell me that if I know about people that have the profile that I contact them and say them that tomorrow 13th or 14th they are going to open the call to collaborators. So, you are the people with perfect profile :) They are going to choose first people that propose him or herself to the project. At same time they are 3 or 4 other several projects about rural and tech's. After this meeting we want to continue development of free networks in Brasil and we're going to work in to get more supporters in contact with "forumdainternet.cgi.br", "Tropixel" and "Saravea.net". Thank you! PD: Some of you can give me permissions to edit Libre-Mesh wiki? My username is "al". Thank you. [1] http://nuvem.tk/

dhcpdiscover

by Pau

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi. What do you think about this? https://github.com/p4u/dhcpdiscover Could be useful for us? It can be executed to know if there are DHCP servers (different to you) in a network interface. root@qMp76:/tmp# dhcpdiscover -i br-lan DHCP ok: Received 1 DHCPOFFER(s), max lease time = 3600 sec. root@qMp76:/tmp# dhcpdiscover -i br-lan -b 172.30.22.1 DHCP offer comming from the banned addr 172.30.22.1, ignoring it DHCP problem: No DHCPOFFERs were received. Could be used for knowing if a network device is plugged to a WAN modem or not.

#libre-mesh on IRC bridged with libre-mesh on RetroShare

by Gioacchino Mazzurco

Hi! Thanks to help of people on retroshare we achieved to have #libre-mesh on freenode bridged with libre-mesh on RetroShare so now we can chat on bot networks with all, the only glitch is that people on one network will not see people on the other but just on the list, the messages will be relayed by the Bridge nick that will report real author as part of the message This is an important step, RetroShare is a P2P secure and encripted netwok, so there is no need for servers, it is just like mesh but on layer 7 and it is particular important because it will encourage local traffic instead of remote one, and decentralization that is all good for our fredom networks :D Also ipv6 for retroshare is in plan for 0.6 version ( we are at end of 0.5.x series ;) so we will have it soon ) And i am developing the GUI for androis so we will have scure messaging on phone too ( VoIP is in plan we already have some working plugin prototype so soon secure call too :D ) see you!

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi. The web page is down again: http://dev.libre-mesh.org Do you have problems with the server? I could find some server to allow it if needed.

https://libre-mesh.org/ down !!??

by Axel Neumann

Hi, Currently, broswing to https://libre-mesh.org/ results in: 502 Bad Gateway and http://libre-mesh.org directs by to a map (NOT the unsecured libre-mesh project side). Anybody available and able to fix that problem? thanks /axel
