Hi all, I' ve a raspberry pi, but at home I haven' t an internet connection and I use a free wifi. To connect Raspberry so I thinked to use my MAC as router, I went in Preferences->Internet and wireless->Share and I checked Share Internet: Share from: Wifi at computer that use: Ethernet.
But Raspberry still doesn' t connect. What should I do?
When I write in Raspberry terminal (LXTerminal)
Code: Select all
ifconfig
there are two result
Code: Select all
eth0
with some infos and
Code: Select all
lo
with some infos, but if I write
Code: Select all
iwconfig
the result of each one is
Code: Select all
Interface doesn' t support scanning.


I' m using Mac os 1.8.2 and Raspberry Pi with Raspbian.

Help me, Thank you!!!

Well, iwconfig is for configuring WLAN, so without a WLAN device, no Wlan configuration.

1. Turn off your firewall in Lion to prevent any interuption.
2. Turn on Internet Sharing in Lion (Share Wlan to Ethernet)
3. Type "ifconfig" in terminal in Lion and see what IP your bridge0 has (should be 192.168.2.1)
4. type "dhclient eth0" in terminal on your Raspberry. If you don't get an IP from Lion try the following.
type "ifconfig eth0 192.168.2.2" and then "route add default gw 192.168.2.1 dev eth0"
5. Now ping a server e.g. "ping 8.8.8.8" (google nameserver) and check if it replies. If everything went well then check if /etc/resolf.conf has a line like "nameserver 8.8.8.8" (or whatever dns-server you prefer) Everything without the quotes " off course.

good luck!

OK :D now I need to connect my Raspberry Pi to internet with mac, I had the opportunity to use a modem, so I didn't try.
I'm trying now, if I type
Code: Select all
ping -c 5 8.8.8.8

the Raspberry seems connected, but if I try to browse or also try to type
Code: Select all
ping -c 5 www.google.com

as result I have
Code: Select all
ping: unknown host www.google.com


Help me :D What should I do?

Dude, if it replies with "ping 8.8.8.8" but not with "ping google.com" then your /etc/resolve.conf isn't set correctly. It should have a line like e.g. "nameserver 8.8.8.8" (like i allready wrote previously)
