Hi folks, I hope some one has an answer for this one. I have only just recenlty set up a small dial-in modem pool for PPP and I am having some wierd problems. If any one has a really good reference to point me to that will do. To simplify testing I have a test machine off the local network and plugged directly into one of the PPP server's dail-in serial ports. Let's call it the client. I log in with kermit and then fire up pppd on the server side. I exit kermit and fire up pppd on the client side. I then pretty quickliy start getting "Unknown protocol (0x4465) received" messages on the client side. The number in parenthesises changes randomly. The server side is also logging messages such as "demuxprotrej: Unrecognized Protocol-Reject for protocol 17509!". The ppp link usually is established, but I am unsure what is causing the "Unknown protocol" messages. Both pppd's are the same version (well one is on 2.1.0 and the other 2.2-ALPHA.) The problem only gets worse when I acutally dial-in, but this I suspect could be noisy lines. Does anyone know what could be causing this? Is it bad hardware? Both machines have 16550 UARTS (a boca atio6 on the server). The server is a DX2/66 and the client is a P5/120. Below are the options files I am using: client: /dev/ttyd0 115200 debug crtscts modem passive domain neuro.virginia.edu noipdefault defaultroute server: debug 128.143.244.161:128.143.244.32 domain neuro.virginia.edu netmask 255.255.255.0 proxyarp crtscts passive modem thanks, Adrian adrian@virginia.edu ---->>>>| Support your local programmer, System Administrator --->>>| STOP Software Patent Abuses NOW!
