Timeout when trying to connect to the device

hdang

Hello,
I am new to ARTIQ and am currently setting up our Sinara system according to the ARTIQ manual.

I successfully managed to obtain the device binaries and flash them onto the device, but when I try to ping the device in the command prompt I get a timeout error. The device is currently connected to the PC via ethernet through a network switch but directly connecting it to the PC also doesn't work.

I tried pinging the IP address as reported by the device during startup (monitored using PuTTY), as well as the default IP 192.168.1.75 stated in the manual, both without success. The LED labeled 0 next to the ethernet port is on when plugging in the ethernet cable and the cable itself works fine with other devices. Am I missing something?

Here is the information reported by the device during startup:

hdang the default IP 192.168.1.75

This is not useful, the device has only one IP 10.34.16.100.

Pinging the device IP 10.34.16.100 unfortunately results in a timeout.

Is there a way to find out if the error is caused by my PC or the Sinara system?

Ping another known-good 10.34.16.* IP from the same PC?

Verify your networking setup. Especially check that your computer will look at that interface when trying to connect to Kasli's IP address. E.g. by adding an IP to the interface that shares a network with Kasli's IP, e.g. 10.34.16.80/24.

Thank you for your replies!

The problem was that the Kasli's IP 10.34.16.100 was not on the Windows routing table. Network packets sent from my PC with the IP 10.64.16.80 therefore didn't reach it.

I followed this guide to add a static route to the routing table:
https://www.howtogeek.com/howto/windows/adding-a-tcpip-route-to-the-windows-routing-table/

Here is the specific command that I used in case somebody else also has this issue:
route -p ADD 10.34.16.100 MASK 255.255.255.255 10.64.16.80

You can find out the IP of your PC by running the following command in the command prompt:
ipconfig

Or just set the netmask to something more sensible e.g. 255.255.255.0, then everything for 10.34.16.* will be sent to this interface.

Thanks for the tip!
