Re: [MirageOS-devel] Routing.No_route_to_destination_address running Mirage web server

[Luke Dunstan <lukedunstan81@xxxxxxxxx>]

Supposedly the unikernel is not seeing an ARP response for
192.168.1.103. What is at that address? Presumably the machine running
the HTTP client, but not dom0 which is working fine? Would you be able
to run tcpdump on dom0 to capture the packets on xenbr0 during the
problem? Maybe also ping 192.168.1.103 from dom0 afterwards in the
same capture?

Best regards,
Luke
