I guess Ron also did some similar work? I don't recall if I mentored the project or whether Ron did, or to what extent there was collaboration. The work enabled native IP stack through either TAP/TUN devices or use of pcap. I believe all the relevant work is reflected in https://github.com/Plan9-Archive/yiyus-vx32, and I believe this also collects most of the work Ron did. I think that this was enabled by setting PLAN9TAP / PLAN9PCAP in the 9vx Makefrag. N.B. The Plan 9 there is also 10 years old and may not be a great reflection of what you'd get from 9front or any other current systems (sorry, I don't know who's actively doing what anymore). Hope this is helpful. Kind regards, --dho On Sun, Dec 6, 2020 at 10:27 PM wrote: > > Hello, > > I tried out plan9 on 9vx today, and things worked well except for network= ing.

Not that that has anything to do with your current problem. I wonder why it says DHCP failed instead of no success with DHCP. Can't help you with the tun/tap stuff. Maybe at that layer everything is working properly and you just need to do a manual ipconfig(8) inside 9vx.

You are right, it does say "no success with DHCP".

The exact error is "Invalid address length 4 - = must be 6 bytes". I tried a few others including 0.0.0.0 but none of t= hem worked. Not specifying this argument however doesn't trigger any co= mplaints.

Perhaps it's time to p= eruse the man pages for ip! But I have to put this down for now and will co= me back to it this weekend.
