| The cloud9 IDE comes up on port 3000. Try accessing <a href="http://192.168.1.27:3000">http://192.168.1.27:3000</a> | | |
| <p> | | |
| Cloud9 data files are stored in /var/lib/cloud9 on the board. | | |
| <hr size=5> | | |
| Networking: You can use the beaglebone over USB network, by ejecting it (go to Windows Computer, then right-click the beaglebone device, and select "eject"). Supposedly, the beaglebone comes up with networking on 192.168.7.2, from the host machine, but I didn't see it. | | |
| <p> | | |
| The beaglebone will automatically start a network connection if an ethernet | | |
| cable is plugged in. On my network, the board shows up at address: 192.168.1.27 | | |
| <p> | | |
| The following services are running, by default (12/2012 image of Angstrom): | | |
| bonescript - port 80, for bone101 tutorials and demos | | |
| cloud9 - port 3000, for cloud9 IDE | | |
| gateone - port??, for network ssh into board | | |
| <p> | | |
| you can see the status of things with: | | |
| systemctl status bonescript.service | | |
| <p> | | |
| systemctl | | |
| <p> | | |
| I stopped bonescript, because I wanted to install lighttpd, which I did | | |
| as follows: | | |
| <p> | | |
| systemctl disable bonescript.service | | |
| systemctl stop bonescript.service | | |
| opkg -V2 install lighttpd | | |
| opkg install lighttpd-module-cgi | | |
| <edit /etc/lighttpd.conf to allow CGI> | | |
| /etc/init.d/lighttpd restart | | |

| Page 54 of the reference manual has the GPIOs for P8 (right side of board, with ethernet connector on top) | | |
| <p> | | |
| Page 59 of the reference manual has the GPIOs for P9 (left side of the board) | | |
| <p> | | |
| GPIOs used by various scripts: | | |
| * P8.1 - GND - ground | | |
| * P8.3 - GPIO1_6 - sys gpio 38 | | |
| * P8.11 - GPIO1_13 - sys gpio 45 | | |
| * P9.6 - VDD_V5 - 5 volt source | | |
| * P8.12 - GPIO1_12 - sys gpio 44 | | |
