Wondering if anyone has built a mesh-only NNTP presence. NNTP is well suited for decentralized group messaging, Everyone could have a NNTP server OR there could be 1 or 2 on each local mesh area.  NNTP is scalable, distributed and decentralized and for this reason I think it would work well on the mesh.

I've built an email (SMTP/IMAP4) server and NNTP server on a Raspberry Pi and attached it to one of my two nodes.  I do believe we could port a couple of the ham radio related usenet groups onto the mesh, but I've chosen NOT to at this point because I really don't want to rely on the public internet.  Currently have just a few local newsgroups created on it but there are just test articles in the message base.

Anyone else want to try to try and give this a whirl to see if it really makes sense or not? I'm willing to build some IP tunnels through the internet to other mesh areas if there is other interest.

Hi,

You cna install OpenBCM software whre you have typical BBS with W0RLI forward via telnet to other AX.25 Packet Radio BBS.  OpenBCM have SMTP/POP3 server and NNTP server. You can get access to OpenBCM via http web browser to read and post or use Mail client like Thunderbird to read and post to OpenBCM via NNTP reader or via SMTP.

I have use OpenBCM on my Raspberry PI and working very nice and I have forwarding with other (stil exist) Packet Radio BBS and local users can connect to my system use different way

http://sp2ong.ampr.org:9080

or via NNTP/SMTP/POP3 via Mail client

You can download OpenBCM from http://dnx274.org/baybox/pages/download.html

I am interested in your project. However I am a newbie at this mesh stuff. Fair IT background, but been out of the business for 15 years now so all information subject to brain scramble.

I live in a remote desert community. Few hams local, however we are trying to do some long range RF hops to expand the mesh.

Interested in news feeds, e-mail and tunneling.

I will be here in the southern AZ desert until May or so when we move to Maine. Again a very rural area. From there we will head to my daughters farm in Brazil sometime in January. Again a very remote area. so setting up news, email and tunneling would be of great interest.

How do you suggest we proceed?

I have Pi and stack of meshed routers in hand.

Will look into OpenBCM on a separate rPi... I already have Postfix, Dovecot and Innd2 installed and working on my local mesh and don't want to lose the work already done. I'm probably doing it the hard way, but I can already send mail between users on the rPi using Postfix/Dovecot and already have local working newsgroups on Innd2. I chose these apps because they are widely available, easy to configure and for the most part industry standard.

Will contact you when I'm ready to set some tunnels up.

Thanks for the reply.

Hi,

Ok you can download my working OpenBCM on RPI:

http://hamnet.ugu.pl/download/obcm-rpi-full.tar.gz

Add user and group "bcm" with home dir /usr/local/bcm. Restore archive below in /usr/local/

chmod -R bcm.bcm /usr/local/bcm

Change in file /usr/local/bcm/init.bcm own call and port number for services default is:

http 9080

smtp 9025

pop3 9110

nntp 9119

copy to usr/local/bin file /usr/local/bcm/bct

BCT is terminal login to OpenBCM

add in /etc/rc.local command

su bcm  /usr/local/bcm/startupbcm

to start up OpenBCM on RPI up

when you start up OBCM you can access to OpenBCM

http://you_ip:9080 and login with your call but before this you must login via on terminal use "bct" to create account and add password with command after login

A TTYPW

You can see own setting use command:

A

Change language:

A S GB

You can find manual (90% translate to english) in /usr/local/bcm/msg

OpenBCM_1.07_Docu_English_29.12.2006.pdf

You can download sources OpenBCM modify by me to compile on RPI

http://hamnet.ugu.pl/download/sobcm-1.07b12-rpi.tgz

and complie with "make"

I thing that instead GRE link is better you cna run on RPI AmprNet GW (you can register on http://portal.ampr.org) after this your RPI will part of global AMPRNet network with ip addres 44.xx and your server and other local users via this amprnet will be have access to others amprnet network.

When you setup AmprNet GW you can simple connet to my server http://sp2ong.ampr.org

You can setup OpenVPN or RPI to make tunnel to users ham radio to access from Internet.

If try setup of AmprNet GW on RPI you can use ampr-ripd download from

http://www.yo2loj.ro/hamprojects/

and create script to run like me below and change from 44.165.32.xx to own IP

Hi,

I have replace file http://hamnet.ugu.pl/download/obcm-rpi-full.tar.gz

new version full package contain binary "bcm" for RPI and Linux after restore archive

please copy bcm.linux to bcm for Linux and bcm.rpi to bcm for RPI

Archive include 2 version terminal to login OpenBCM bct.rpi and bct.linux

Hi,

We have discus about Amprnet gw and BBHN in

http://www.broadband-hamnet.org/hsmm-mesh-forums/view-postlist/forum-18-how-we-used-hsmm-mesh/topic-660-hsmm-mesh-and-amprnet.html

I have show example on picture my local configuration.
