[SailfishDevel] Question about connecting a Sailfish phone to Ubuntu Linux box

Wed Jul 24 06:57:57 UTC 2019

Eli,

I take the point that in this situation all bets are off, so it looks 
like I'll have to change the i.p. addresses on my network of development 
machines and development VMs. An inconvenience, but at least it's only a 
one-off change,

Regards,

Sahlan
