configuring the IPv4 gateway on the core device

Marwanh7

Hi,

I am trying to configure the ip and gateway address for the core, the command artiq_coremgmt -D 192.168.1.75 config write -s ip [new IP] works for changing the ip. I am not able to find a command for changing the gateway, is changing the gateway for the artiq board doable ?

A gateway is normally not necessary. Do you have issues without one?

No issues right now since the board is connected directly to my PC, however my boss is trying to have the device on the network and for him to have the board talk back to his PC we would need to be able to change the gateway.

The TCP/IP stack (smoltcp) uses a trick where it stores the MAC address of the incoming packets in its cache instead of using ARP. Since the device is a server only, it never spontaneously sends a packet to a new host, and all the packets it sends are using MAC addresses discovered using this scheme. So it will automatically send its replies to the MAC address of the gateway and you do not need to configure it.

Great thank you, that works sb10q
