this kernelpatch for kernels 1.3.56,57,58, ?? makes 3 things. - removes the ipx-send bug. BIG THANKS to Volker Lendecke. the problem was that sometimes the sendto function hung. - ipx rip/sap packets comming from internal net must change there source address from internal net/node to the device net/node. The problem was: By configuring mars_nwe at the internal network, the rip/sap socket gets the network and node address of the internal net. Then, by sending rip/sap packets over this socket to the several devices the rip/sap packets don't have the device net/node, but the internal net/node. - an existing route should never be overwritten by an route over the internal net. The problem was: By running dosemu at the same workstation as mars_nwe the dosemu automaticly changes the route to a nearby server to route over the internal network and this destroyed the real route over a device to this server. You must be supervisor and then you must start './patchme' . Martin Stover
