Cannot ssh to Freerunner
Hi, I might be a bit retarded (one never knows), but for the life of it I cannot ssh into the FR: Host IP: 192.168.0.101 DNS: 192.168.0.100 On the host I do as root: ifconfig usb0 192.168.0.200 netmask 255.255.255.0 ssh [EMAIL PROTECTED] No route to host ... ? Oh, this is the most recent QT Extended plus the current mwester kernel. Is there a fundamental error somewhere?

If you have eth0 with 192.168.0.101 (i guess it) you'll have a route for the entire class trough it. So assigning 192.168.0.200 to usb0 is not sufficient. Try route add -host 192.168.0.202 gw 192.168.0.200 after ifconfig, wait about 20 seconds and try to ping/ssh again.

Re: Cannot ssh to Freerunner
If your host is in the same subnet (and has a ethernetcard too), you should use subnetmask 255.255.255.248 for connecting to the freerunner. Otherwise the kernel tries to send out the packages for the freerunnner over your networkcard. (thats what i think, but i'm no network pro ;) - they never reach your freerunner plugged on usb. rgds daniel On Mon, 06 Oct 2008 11:06:49 +0200 Nicolas Linkert [EMAIL PROTECTED] wrote: Hi, I might be a bit retarded (one never knows), but for the life of it I cannot ssh into the FR: Host IP: 192.168.0.101 DNS: 192.168.0.100 On the host I do as root: ifconfig usb0 192.168.0.200 netmask 255.255.255.0 ssh [EMAIL PROTECTED] No route to host ... ?

Re: Cannot ssh to Freerunner
Well crap, sorry about that. It's supposed to be -j ACCEPT, not just 'ACCEPT'. -j means 'jump' and is followed by a chain name or target, in this case ACCEPT telling the firewall to permit matching traffic. I'm guessing your FORWARD chain is either empty with a policy of ACCEPT, or some form of 'allow all' rule, so the traffic gets through without those additions. ;) j On Tue, 07 Oct 2008 07:21:34 +0200, Nicolas Linkert [EMAIL PROTECTED] wrote: Great! This works for me. The only thing I had to change were the ACCEPT commands since they were not accepted.
