I have a wi-fi router, a linux machine (ubuntu) a Mac, and an iPhone. The router has the address 192.168.1.1, the ubuntu machine connect to that with ethernet (192.168.1.2) and the Mac connect to the router via Wi-fi (192.168.1.6.). Netmask is 255.255.255.0.
I share the 3G internet from the iPhone to the Mac via USB, and want to share it to the ubuntu machine too.
How can I do this ? route command output on ubuntu
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface

@KissGyörgy First, keep your calm and don't panic. Disabling the internet sharing and running
ifdown eth0 && ifup eth0
on the Ubuntu machine will restore the old state. Make sure you share the correct connection. Before you typed anything on the Ubuntu machine, could you still connect to the Mac, for example via ping? – phihag – 2011-10-29T00:04:55.127I cannot log in to the ubuntu machine after I set up Internet sharing on the mac. (no screen on that machine) – kissgyorgy – 2011-10-29T00:23:16.943
@Walkman Are you configuring your Ubuntu machine via ssh from the Mac? If so, that's a pretty important detail you should have included in the question. What is the Mac's routing table before/after you enable internet sharing? – phihag – 2011-10-29T00:27:48.780
here is my local network: https://cacoo.com/diagrams/VcBnZIl1GB3EDsGv
– kissgyorgy – 2011-10-29T00:37:49.500yes, I manage it via ssh. here are routing tables for Mac. http://pastie.org/2776130
– kissgyorgy – 2011-10-29T00:44:30.693@Walkman If I'm reading these tables right (Is that the output of
– phihag – 2011-10-29T00:52:38.513route
orip route
?), the dropped route to 192.168.1.2 should have no effect, but is also not necessary for connection sharing. You may want to contact the experts over at http://apple.stackexchange.com/ .I cant even stop sharing from mac settings. It stays checked all the time... I have to restart because ifconfig en1 down and up dont do the trick... – kissgyorgy – 2011-10-29T00:52:57.420
its from
netstat -nr
– kissgyorgy – 2011-10-29T00:54:08.433@Walkman If you can't stop sharing the network while you're sitting in front of the Mac, it's definitely a bug in OS X. Ask on http://apple.stackexchange.com why that's the case.
