I have been playing around with JNOS for several years now and while its a good simple packet program to assemble and get going, it has a few problems. Obviously it does HTML nicely though.

I am yet to work out why there is a memory leak but its a goodie. The uptime can be days but it gets a bit lethargic and slows right down. Specially so when you have several AXIP links running.

JNOS runs on DOS very well but again, it gobbles up the memory quickly and does not use upper memory very well. But after saying all that, JNOS has everything PACKET you want to compile into it.

There are other NETWORK programs that are just as good under DOS. TNOS is ok but much better under LINUX.

Here are a list of several Packet programs you may like to try and I have had great success with. FBB, BPQ, WINPACK, and TPK
