Libresdr; Applying only powersupply there is no ethernet connection

[pa3gsb]

Hi,

I use the latest firmware running from sd card.

Applying only powersupply and connect the ethernet to PC.

It is not possible to ping to the libresdr. Using a port scanner the libresdr is found but no active services are found; so no ping or other connection can be made.

Connect the PC via usb and apply the power via usb there is a connection.

Are there ideas where to look?

First ethernet cable, then power on. DHCP client does not work in the background if fails.

[pa3gsb]

i do follow that procedure. Ethernet cable first.

[sq6emm]

tezukafw is a DHCP client sob your comfort should be DHCP server.... Try connection to a network router/switch

[pa3gsb]

i have done that as well. Also without luck.

[F5OEO]

If there is an issue with dhcp, you can try to set static ip address to eth :

• Boot with USB
• Edit config.txt, modify fields with a proper ip address

[USB_ETHERNET]
ipaddr_eth =
netmask_eth = 255.255.255.0
gateway_eth =

-Eject

Reboot without USB

[F5OEO]

Can you try with the latest 0.0.95 version ?

[pa3gsb]

I have tried your latest 95 version. In the router i see that the libre is getting an ip address.

But iam not able to ping or work with the device; when using the port scan i do no service / ports coming available.

i have tried a dynamisch and static address both are not responding to pings.

Only having the usb connected; it is working.

[F5OEO]

Can you plug the serial usb cable (power) and monitor messages (even ssh in it) : this is serial link at 115200.

[pa3gsb]

setup:

• modified an usb cable; removed the 5V line. connect this modified cable to pc for putty terminal.
• connect the ethernet cable.
• connect the usb - otg to only power supply.

Result:

• no ping to libresdr.

• libre sdr got ip address. but no services / ports available on the interface / ipaddress.

found the problem

ip route

default via 192.168.2.254 dev eth0
192.168.2.0/24 dev usb0 scope link src 192.168.2.100
192.168.2.0/24 dev eth0 scope link src 192.168.2.146

removed one route:
sudo ip route del 192.168.2.0/24 dev usb0

now the ping is working (both sides)

how to avoid to get a double entry?

The problem is that the default ip addressing of Ethernet over USB is 192.168.2.0/24 and it seems your local network has the same IP addressing... So you need to reconfigure in config.txt that the Ethernet over USB is on another network ;)

I solved the problem;

Used indeed a seperate internet mask for the ethernet and usb ethernet ip address.

So the versie 95 is working ok.

Thanks for the support.
