Trouble setting up.
Dear Tom,
I am trying to implement your app a Pi, i followed the instructions to the letter but can't seem to get an ssh connection to 172.16.254.1.
I also don't know which user to connect with.. root or pi.
So i tried ssh [email protected]
and ssh [email protected]
When i try to ping it via command line it doesn't respond.
ramon@Zoe:/home/ramon 13:57 Mar 31
» ping 172.16.254.1
PING 172.16.254.1 (172.16.254.1) 56(84) bytes of data.
^C
--- 172.16.254.1 ping statistics ---
14 packets transmitted, 0 received, 100% packet loss, time 13103ms
I do have the eth both setup good i think, this is the output from ifconfig on the Pi:
pi@QPortal ~ $ ifconfig
eth0 Link encap:Ethernet HWaddr b8:27:eb:1c:e4:09
inet addr:192.168.178.25 Bcast:192.168.178.255 Mask:255.255.255.0

And this is the output from route on the Pi:
pi@QPortal ~ $ route -nNvee

192.168.178.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 0 0 0
Any ideas? I really hope you can help me solve this.
Can you ssh in on the other ethernet adapter?
what's the output of netstat -anp like (run as root)
Yes, i can access it via ssh on eth0.
Hope this helps, and thanks for your time and help in advance.
