sparc-solaris networking not working

[Michele Denber]

I started my virtual SparcStation 5 like this:

$ qemu-system-sparc -nographic -bios ss5.bin -m 32 -rtc base="1999-04-19" -hda sunos414.img -net nic,model=lance -net user,hostfwd=tcp::4422-:22,hostfwd=tcp::4423-:23

following the recommendation here: https://stackoverflow.com/questions/53315086/transferring-file-to-virtual-machine-qemu-using-tcp-port-2222-not-working

But when the guest starts, I can't access my LAN (192.168.0.x).

And in the Ubuntu host:
$ netstat -tulpn | grep qemu
(Not all processes could be identified, non-owned process info
 will not be shown, you would have to be root to see it all.)

tcp        0      0 0.0.0.0:4423            0.0.0.0:*               LISTEN     

The funny thing is that if I start ftp to a machine on the LAN, it will connect OK but I can't transfer any files (it just hangs when I do a PUT).

sunss5# ftp 192.168.0.78
Connected to 192.168.0.78.
220 avon FTP server ready.

Or even ftp to the ubuntu host doesn't work

sunss5# ftp

What am I doing wrong here?
