JSModem

Provides a virtual modem device for JSLinux platform. It is a result of studying project conducted on PC emulator that was implemented in JS by Fabrice Bellard (see http://bellard.org/jslinux). There is a screencast discussing this project http://www.youtube.com/watch?v=MEsmgHrKQYM.

Licensing

  • The software behind jslinux emulator is the intellectual property of Fabrice Bellard (see jslinux.org for further details).
  • The rest of the patch is licensed under MIT license (see copy of it in LICENSE).

Installation

  • Get a copy by cloning the repo from [email protected]:ewiger/jsmodem.git

  • Run make all in jsmodem/emulator to download and patch JSLinux from http://bellard.org/jslinux (This step is still valid but left as a fallback. Right now the jslinux version is in sync with the version on the website of Aug 20, 2011).

  • Start serving JSLinux locally with sudo ./serve.sh

  • Navigate to http://localhost:2080/ This should boot the guest system.

  • Login as root and run ./ppp_up to bring up the ppp interface. Check it with ifconfig and ping.

Requirements

JSModem script is heavily based on JSLinux project, hence browser must be modern enough to support it. Another project websockify provides websockets abstraction with fallback to flash.

To serve on host system one will need

  • python 2.6+

  • bash

  • sed

  • gawk

  • grep

  • pppd

  • socat

  • iptables

Tested

Internet connection was tested on

  • host server: linux 2.6.35 - ubuntu 10.10 Maverick, linux 2.6.38-11 - 11.04 Natty Narwhal host client: Chrome 12.0.742.112 (linux), FF 3.6.8 (linux), Chrome 14.0.835.202 (linux)
