Then, how can I access to these bhyve guests? assuming that you can give each guest a name, use them like this: > root@mm2:/home/vixie # cd /usr/local/rtty > root@mm2:/usr/local/rtty # ls -l dev > lrwxr-xr-x 1 root wheel 11 Dec 25 2015 demo -> /dev/nmdm2A > lrwxr-xr-x 1 root wheel 11 Feb 8 04:08 hpfeeds -> /dev/nmdm8A > lrwxr-xr-x 1 root wheel 11 Jan 15 02:54 usql -> /dev/nmdm5A > lrwxr-xr-x 1 root wheel 11 Jan 1 2016 x -> /dev/nmdm3A > lrwxr-xr-x 1 root wheel 11 Jan 15 21:44 yeti-dns -> /dev/nmdm7A as you can imagine, i'm using the B ports for bhyve consoles. > I have tried to add vnc channel, but it doesn't works ..:( it's pretty straightforward. i wrote rtty in 1990 when serial lines weren't virtual. > [mm2.redbarn:amd64] console yeti-dns > connected > (use (CR)~? for minimal help; also (CR)~q? and (CR)~s?) > [authorized] > [vixie@/dev/pts/6 connected] > > FreeBSD/amd64 (yeti-dns.tisf.net) (ttyu0) > > login: > > FreeBSD/amd64 (yeti-dns.tisf.net) (ttyu0) > > login: > [rtty exiting] i like rtty better than "cu" or "tip" because multiple people can connect at the same time, and because everything is logged always: > root@mm2:/usr/local/rtty # ls -l log > -rw-r----- 1 root wheel 4253207 Feb 17 05:44 demo > -rw-r----- 1 root wheel 218105 Feb 12 21:39 hpfeeds > -rw-r----- 1 root wheel 184779 Jan 15 22:57 usql > -rw-r----- 1 root wheel 1374759 Feb 3 04:08 x > -rw-r----- 1 root wheel 257801 Feb 17 09:03 yeti-dns huh. i guess i need to rotate those. -- P Vixie
