When I watch Pavel's image boot, then type ifconfig after logging into root, the pitaya reports nothing. The corresponding line with the internet address is simply not there.
During boot it does say "Failed to start LSB: DHCP server. " New at this, no idea if that is important.
Hi Steve,
Looks like your Red Pitaya doesn't get any response from a DHCP server and uses the default IP address as it's described at the following link:
http://wiki.redpitaya.com/index.php?tit ... figuration
Could you connect your Red Pitaya to a DHCP server? There are several possible solutions depending on your network layout. I often use one of the following solutions:
- connect Red Pitaya directly to my Windows laptop and use the "Internet Connection Sharing" functionality that enables a DHCP server on my laptop,
- connect Red Pitaya to a small network router that has a DHCP server.
In case of the Debian based system, I did not configure any default IP address. That is why it behaves as you describe. I'll check how the network is configured on the original Red Pitaya SD card and I'll copy it to my Debian configuration.
Cheers,
Pavel

To configure a default IP address if there is no DHCP server, the following lines should be added to /etc/dhcp/dhclient.conf on the Debian based system:
Code: Select all
timeout 20;
lease {
interface "eth0";
fixed-address 192.168.1.100;
option subnet-mask 255.255.255.0;
renew 2 2030/1/1 00:00:01;
rebind 2 2030/1/1 00:00:01;
expire 2 2030/1/1 00:00:01;
}
I'll add them to the next version of the Debian based SD card image.

Thanks Pavel! I added those lines, that did not seem to do it, but then added the lines described in your previous post:
"Looks like your Red Pitaya doesn't get any response from a DHCP server and uses the default IP address as it's described at the following link:

Working fine now, I can now log in over the Ethernet cable. Much easier for classroom demonstrations. Your quick response and help are much appreciated.
Steve

Here is a new version of the Debian based SD card image that contains the default DHCP lease configuration from my previous comment. If no reply from the DHCP server is obtained within 20 seconds, the IP address will be set to 192.168.1.100.
