I want to do SLIP between an AT-class PC and a SPARCstation running SunOS 4.1. I imagine I would need a SLIP server from Sun, but I'm not clear what I would need on the PC end. I've got FTP's PCTCP Plus, but it's still not clear from looking at that what exactly things like telnet and rlogin would be talking to on the PC, and how I would get them. (The "SLIP drivers" that FTP supplies seem to be the SLIP servers I would need for the Sun, but the versions of the OS they support are too old.) Conceptually, it seems I need something that replaces the kernel, and something that drives the serial port that the kernel would talk to. What exactly is involved? (In reality, I would be talking asynchronously to a terminal server, and it would talk to the Sun, so I'm not sure I even need to bother getting SLIP for the Sun -- the server I initially contact should take care of that.) Thanks. -- Internet: chas@uchicago.edu

Er, I think you're making it too complicated. You don't want to replace any kernels. SLIP would only be involved in the link between the PC and whatever its connection to the network is. If your Sparcstation is connected to an ethernet, and that ethernet is connected to a terminal server, and you want your PC to speak SLIP to the terminal server, you don't need to do anything to the Sparcstation. People don't normally talk about "SLIP servers". They talk about SLIP drivers, because SLIP is a form of network media as far as TCP/IP is concerned. So you run a TCP product with a SLIP driver on your PC, and make sure the port you connect to on the terminal server is in SLIP mode, and you should be moving packets. One caveat is IP address assignment. Your PC must be assigned an IP address. Some terminal servers tell you the IP address they want your PC to use when they put the port in SLIP mode. Then you can proceed to use TCP applications just as if you were on an ethernet, only slower. - john romkey Epilogue Technology USENET/UUCP/Internet: romkey@asylum.sf.ca.us voice/fax: 415 594-1141

From: Charles Blair Subject: What do I need to get to do SLIP? I want to do SLIP between an AT-class PC and a SPARCstation running SunOS 4.1. I imagine I would need a SLIP server from Sun, but I'm not clear what I would need on the PC end. I've got FTP's PCTCP Plus, but it's still not clear from looking at that what exactly things like PCTCP Plus comes on ~25 flavors, one for each type of network card we support. The are numbered PC-201 to PC-227, (a couple numbers are skipped). There are two ways to get a SLIP driver with a PCTCP kernel. One is PC-205 which is a linked in SLIP driver, the other is PC-210 which includes a generic SLIP kernel which can be used in conjunction with Clarkson's SLIP packet driver. == Gordon Lee FTP Software Inc == voice: (617) 246-0900 26 Princess St == fax: (617) 245-7943 Wakefield, MA 01880
