Hi there! I'm having a lot of trouble with my ppp dialup router. It is really driving me crazy!! Last time I wrote about this, someone told me about upgrading to FreeBSD 2.1.5, 'cause 2.1.0 has bugs in the ppp daemon. Ok, I have done it. the "Address already exists" message is gone, but now I have OTHER problems :( When I connect to the FreeBSD machine using Windows95 dialup networking, everything works (apparently) fine, I can do a telnet session and spend an hour working with no problem... but when I start Netscape or something that puts a more heavy traffic on the line, pppd begins to send messages to the console, as follows: ppp0: bad fcs /kernel: bad fcs and the connection freezes. The modem does not hang, the FreeBSD box keeps working normally, but no traffic occurs between the modems anymore. My checklist is as follows: 1. Modem cables: Ok 2. Modem setup: USRobotics Sportster 28.8, initialized at 38400bps using cu (getty uses 38400bps too). 3. pppd options file: modem passive domain xxxx.xxx.xx crtscts kdebug 1 debug -mru -pc mru 1500 proxyarp netmask 255.255.255.192 4. Kernel compiled with GATEWAY and ARP_PROXYALL options. 5. The serial port UART is a 16550A. 6. The modems are using error correction. What could be happening here? Give me some hints, PLEASE!! this situation is ruining my project of a unix dialup router, and I don't want my department to spend lots of money on an access server, terminal server or something like that instead. Thanks in advance! +-----------------------------------------------+ | Victor Manuel Carranza Gonzalez | | Unidad de Internet/Red Cientifico-Educativa | | Depto. de Procesamiento Electronico de Datos | | Universidad de San Carlos de Guatemala -USAC- | | | |e-mail: victor@usac.edu.gt, | |Telefono oficina: (502)4769723 (fax/voz) | | (502)4767719 (voz) | |Telefono casa : (502)4782916 (502)2891037 | +-----------------------------------------------+
