I am looking for some way to get SVR3ish STREAMS or sockets on my 7300. I had heard that either the Starlan software or the TCP/IP software in fact included one or the other beneath the covers, and I'd be willing to pay real money for one of them if this were true. The questions are, A) what is underneath these packages? B) does it support poll() or select()? C) can you load the drivers/kernel hacks necessary without theppresence of a controller card? C) does this stream module Thanks, -dB {amdahl, cpsc6a, mtxinu, sun, hoptoad}!rtech!daveb daveb@rtech.uucp

You've brought up a very interesting point. Can someone just buy the software that puts the "hooks" in the operating system to provide sockets, STREAMS, and RFS?

I have worked with both the STARLAN and ETHERNET cards --- and BOTH will NOT WORK IF THE CONTROLLER IS NOT IN THE COMPUTER. This is due to the device drivers also doing socket handling. I.E. The socket code is not independant of the controller driver. HOWEVER, both cards will run WITHOUT having the controller hooked up to other hosts. Since the driver han have a conversation with the controller card, programs will work. Jonathan Sadler Computing Systems Lab (CSL) Unversity of Wisconsin - Madison

What Starlan has in it is a pre-SysVr3.0 version of streams (known as "B+" streams) which is used mainly inside the driver. The interface to streams is not the standard system call interface, but is actually done via ioctl() calls to the starlan driver. TCP/IP for the 7300 does not use streams, rather the Wollongong implementation of BSD sockets, similarly done through ioctl() calls to the driver. The /usr/include/sys/*.h files have BSD-isms in them for two reasons, one to support Wollongong TCP/IP, and two because large portions of the Unix PC kernel are BSD 4.0 derived (the paging system, for example is purest BSD); however only the barest semblance of the Berkeley extensions remain in the code. So, in summary, you can get a reasonable semblance of streams with Starlan software, and a reasonable semblance of sockets with the TCP software (although adding your own streams modules to the Starlan software would be a challenging proposition, to say the least...) >-Lenny -- Marc Mengel attmail!mmengel ...!{moss|lll-crg|mtune|ihnp4}!cuuxb!mmengel
