For me, it works very well with kernel 1.2.13 as well as 1.3.x kernels. I think this release provides some advantages over the other programs, as it does not require a kernel patch, and it works fine when you reconfigure your IPX interfaces while ipxd is running. With IPX over PPP this should make remote access to IPX networks via Linux very convenient. Although ipxd does not require a kernel patch, it works fine with the full internal network, which can be activated since Linux 1.3.60.
Sockets bound on the internal net can request any node number they like.
Currently there's a lot of discussion about this topic on the linware mailing list.
