Hi Larry,

Thanks, we're looking into it.

Just wondering what d8a70aede1c95108c0296f6a6abfebaa is... would you mind checking this out?

# md5sum /tmp/tmpcfd_* | grep d8a70aede1c95108c0296f6a6abfebaa

And see what the content is of these files (if they are still on your disk)?


Thanks,
Franco

Hi Franco,

These two files returned immediately after rebooting at 00:03. Since looking at the time stamp on these files and extracting more detail, one of the files was updated at 9:52:28 - the content is the same.

I'm only using IPv4.

{"WAN_DHCP":"WAN_DHCP - <ISP Gateway IP>","Null6":"Null6 - ::1","Null4":"Null4 - 127.0.0.1","WAN_DHCP6":"WAN_DHCP6 - inet6"}
