免服务器“微信”Serval Mesh Building Serval DNA for OpenWRT

q15***

有没有人玩这个app啊，The Serval Mesh安卓官方商店有http://developer.servalproject.org/files/，是个免费对讲机，不需要使用手机流量和wifi互联网。靠他自建的wifi蓝牙热点传递信息，可以在出游时那些信号不好的地方使用（当然买个对讲机最好），个人觉得还是挺好的（毕竟人人都有一款手机）。这个帖子是摘抄他们网站的，可以用路由器扩大这个网络的覆盖范围，不知道国内有没有人搞{:soso__15960872840493620282_2:}
Serval Mesh allows people to make voice calls, send text messages and share files with other Serval Mesh users, without requiring infrastructure like satellites, cell phone towers, Wi-Fi hot spots, or radio repeaters.

Since OpenWRT is installed as a complete firmware image that contains the Linux kernel and all selected components, Serval DNA for OpenWRT can only be built as part of a whole OpenWRT build.
This process can also be used to produce the servald binary for openwrt for use elsewhere, for example including in a Mesh Extender firmware build.  But note that the Mesh Extender firmware build process is different (and simpler) compared to that described here.
The Serval DNA build instructions for OpenWRT describe this process in detail.

• Choose a version of Serval DNA to build:
  
  • To build a version under development from a locally edited working copy:
    
    • Appendix A of the Serval DNA build instructions for OpenWRT describe how to set up an OpenWRT feed which compiles directly from your Git working copy of the Serval DNA source code.
      
  • To build a published release of Serval DNA:
    
    • the latest Serval OpenWRT package feed README describes which releases (feed branches) are available
    • the Serval DNA build instructions for OpenWRT describe how to compile your chosen feed branch of the Serval OpenWRT package feed
      
    
    
• Select your target device (architecture) and other configuration options:
  
  • in the menuconfig step of the build instructions:
    
    • select the target platform (Dragino MS12 is used in the examples below)
    • select the serval-dna package as a module: [M]
      
    
    
• The build should produce an IPK file under the bin/arch/packages directory, eg ls -sh bin/atheros/packages/serval*840K bin/atheros/packages/serval-dna_START-2967-gdc588e9-4_atheros.ipk$
• Copy the IPK file onto your OpenWRT device, and install it using opkg. For example scp bin/atheros/packages/serval-dna_START-2967-gdc588e9-4_atheros.ipkroot@192.168.255.1:/tmp/root@192.168.255.1's password:serval-dna_START-2967-gdc588e9-4_atheros.ipk       100%  840KB 635.6KB/s   00:02$ ssh root@192.168.255.1root@192.168.255.1's password:BusyBox v1.15.3 (2012-11-26 07:01:41 CST) built-in shell (ash)Enter 'help' for a list of built-in commands.  ___   ___   ___   ___  _ _  ___   ___ |   \ |___\ |___| | __   |  |   | |   |        [  www.dragino.com  ] |___/ |   | |   | |___| _|_ |   | |___|        [  www.flukso.net   ] ------------------------------------------     [  www.rowetel.com  ] W i F i, L i n u x, M C U, E m b e d d e d OpenWRT Backfire [10.03.1, r33081] Dragino MS12 2.1-beta-2, Build Mon Nov 26 07:30:30 CST 2012root@dragino:~# cd /tmproot@dragino:/tmp# ls *ipkserval-dna_START-2967-gdc588e9-4_atheros.ipkroot@dragino:/tmp# df -hFilesystem                Size      Used Available Use% Mounted on/dev/root                 2.9M      2.9M         0 100% /romtmpfs                    14.6M    716.0K     13.9M   5% /tmptmpfs                   512.0K         0    512.0K   0% /devroot                      2.9M      2.9M         0 100% /tmp/rootmini_fo:/tmp/root         2.9M      2.9M         0 100% /tmp/root/dev/mtdblock3            3.9M    272.0K      3.7M   7% /overlaymini_fo:/overlay          2.9M      2.9M         0 100% /root@dragino:/tmp# opkg install serval-dna_START-2967-gdc588e9-4_atheros.ipkInstalling serval-dna (START-2967-gdc588e9-4) to root...Configuring serval-dna.root@dragino:/tmp# which servald/usr/bin/servaldroot@dragino:/tmp# servald helpServal Mesh version <version>.Usage: dna lookup <did> [<timeout>]...root@dragino:/tmp#
  

You should now be able to use servald on your OpenWRT device.

Building OpenWRT firmware for DragroveOur initial prototype hardware target is the Dragrove MS12.

• the Compile Dragino Firmware wiki page describes the process for building firmware and flashing it to the device
• alternatively, the Motherboard Upgrade Firmware wiki page has instructions for flashing pre-built firmware files
  

Flashing New Firmware From a MacOn a Mac, you can flash the firmware as follows:

• Make the firmware files available by TFTP cp bin/atheros/openwrt-atheros-vmlinux.lzma /private/tftpboot$ cp bin/atheros/openwrt-atheros-root.squashfs /private/tftpboot$
• Manually configure eth0 (wired ethernet) on the Mac to 192.168.255.2, subnet 255.255.255.0, with no router.
• Start the TFTP server on the Mac, e.g.: $ sudo launchctl load -F /System/Library/LaunchDaemons/tftp.plist$ sudo launchctl start com.apple.tftpd$
• Connect the Dragrove to the Mac via ethernet cable
• Create ~/.telnetrc with the contents:192.168.255.1<NEWLINE><TAB>mode line<NEWLINE>Obviously, replace <NEWLINE> by pressing Enter and <TAB> with a single TAB character when creating the file using your favourite editor.
• Power down the Dragrove
• On the Mac, be ready to type telnet 192.168.255.1 9000 as soon as the Dragrove powers up. You may need to type it several times to make sure you get in. If you don't get in within a few seconds, go back to step 6.
• Once you see something like == Executing boot script in 4.580 seconds - enter ^C to abort do press control C.  You should be greeted with a RedBoot> prompt.
• Type the following redboot commands:fis initload -r -b %{FREEMEMLO} openwrt-atheros-vmlinux.lzmafis create -e 0x80041000 -r 0x80041000 vmlinux.bin.l7load -r -b %{FREEMEMLO} openwrt-atheros-root.squashfsfis create rootfsresetFor example, a successful conversation might end up looking like:
  $ telnet 192.168.255.1 9000Trying 192.168.255.1...Connected to 192.168.255.1.Escape character is '^]'.== Executing boot script in 4.580 seconds - enter ^C to abort^C^CRedBoot> fis initAbout to initialize [format] FLASH image system - continue (y/n)? y*** Initialize FLASH Image System...

• When all done, stop the TFTP server on the Mac sudo launchctl stop com.apple.tftpd;$ sudo launchctl unload -F /System/Library/LaunchDaemons/tftp.plist$
