Hi sir, I'm a student of Trento University and I'm working on a network project. I need to create a network like this: PC.1>--ethernet cable-->MAIN_PC(ubuntu linux)>------wireless----->PC.2 PC.1 ip: 192.168.0.1 MAIN_PC ip: 192.168.0.2 PC.2 ip: 192.168.0.3 netmask 255.255.255.0 I followed the instruction of the HOWTO and I made a bridge on MAIN_PC. Previously I set the wireless interface (eth0 - intel 2200B/G) with ad-hoc mode and I gave it a essid and a channel. Without the bridge I can ping from MAIN_PC all the others but I noticed that when the bridge is up I can't ping from the PC.2 the PC.1 (problem nr°1) and I can ping from PC.2 the MAIN_PC only for a short start time (problem nr°2). When I give this command as root: echo "1" > /proc/sys/net/ipv4/ip_forward this is the answer: bash: /proc/sys/net/ipv4/ip_forward: Permission denied Maybe I think this is the reason because I get problem nr°1, is it true? What should I do? I have no idea for the second problem. Can you please help. Sorry for my english, I hope that my explanation were enough clear Thanks a lot Filippo Graziola __________________________________________________ Do You Yahoo!? Poco spazio e tanto spam? Yahoo!
