Good for you! Qemu already has SLiRP networking which was then ported to Bochs.

I’m wondering if there is a way to port Qemu SLIRP networking to PCem. If it is possible, it might not be too easy thing to do.

By the way, updating to QEMM97 didn’t fix the auto-reboot issue in PCem v9 as it did in PCem v8.1.

well, my only issue with the ne2000 is a configurable mac address, for now, a fixed one hardcoded into the source code is there.
And my latest github release can bring PCem to the Internet
(For information purposes, the ne2000 code I have done in my branch is from dosbox with some additions from qemu)

The only problem that irks me is that when I try to run DesqView/X, PCem v9 automatically reboots itself. I’m wondering if updating to QEMM97 does the trick. 🙂

I’m glad that SA1988 got the networking implemented in PCem v9; however, it doesn’t appear to be working too well and needs a lot a work.

I sure hope that networking is implemented and workable in PCem v10! 🙂

networking is now a reality on PCem, check https://github.com/TC1995/src-9 , the ne2000 can now get an ip address through DHCP.

The issue is about TX Transmit events which is missing from my ne2000 implementation, but on dosbox-x it relies on PIC_AddEvent, which is too dosbox specific to be ported

Mutexes and queues are the way I solved that.

As you read your packet stuff it into a queue. Don’t process it, as that takes time.

Then when the NE2000 checks for packets dequeue and pass them up.

Remember to set a filter, or you’ll pass reflecting packets and stuff destined for the host.

Oh I see! that is pcap_open, while I’m used to pcap_open_live.
