Title Body

I want to try some networking projects with Raspberry Pis, and I need to just send packets between a pair of pis. I would be happy as a first step just being able to ping between to Raspberry Pis in ad-hoc mode. I have not successfully done this despite looking at several tutorials and examples online. I have 2x Raspberry Pis with the Debian Wheezy OS installed. I am using the following USB adapter which I installed firmware for on both pis and tested that they work by connected them in managed mode to a router: Bus 001 Device 004: ID 050d:945a Belkin Components F7D1101 v1 Basic Wireless Adapter [Realtek RTL8188SU] Here are is some printouts about the networking information: /etc/network/interfaces at each pi: pi1@raspberrypi ~ $ cat /etc/network/interfaces auto lo iface lo inet loopback iface eth0 inet dhcp auto wlan0 iface wlan0 inet manual address 192.168.2.1 netmask 255.255.255.0 wireless-channel 4 wireless-essid pi-ad-hoc wireless-mode ad-hoc pi2@raspberrypi ~ $ cat /etc/network/interfaces auto lo iface lo inet loopback iface eth0 inet dhcp auto wlan0 iface wlan0 inet manual address 192.168.2.2 netmask 255.255.255.0 wireless-channel 4 wireless-essid pi-ad-hoc wireless-mode ad-hoc ifconfig at each pi: pi1@raspberrypi ~ $ ifconfig wlan0 wlan0 Link encap:Ethernet HWaddr ec:1a:59:46:8e:5a inet addr:192.168.2.1 Bcast:192.168.2.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:26 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) pi2@raspberrypi ~ $ ifconfig wlan0 wlan0 Link encap:Ethernet HWaddr ec:1a:59:46:59:0a inet addr:192.168.2.2 Bcast:192.168.2.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 M
