Does anyone have a version of PC-NFS running over a SLIP line? I know this sounds a bit absurd, running over a serial port, but I'd like to set up a NNTP client, and I can't seen to get ka9q working with nntp. ----- Daniel R. Jeuch Microsoft Corp.

Believe it or not (I couldn't the first time I read it), PC-NFS 3.0 from SUN does have drivers to run NFS over Dialup SLIP. The manual says it can be done, but its on the to-do list here, so I don't know if it actually works. Good luck. Please write back if you get it to run!

Believe it or not (I couldn't the first time I read it), PC-NFS 3.0 from
SUN does have drivers to run NFS over Dialup SLIP. The manual says it
can be done, but its on the to-do list here, so I don't know if it
actually works. Good luck. Please write back if you get it to run!
I've used Interdrive (our NFS client) over SLIP, and I've also used dial-up
SLIP (but not NFS over dial-up SLIP). If I were using NFS over dial-up
SLIP, I'd make sure that both ends were sending (and checking) UDP
checksums. Interdrive does this; I don't know about PC-NFS or BW-NFS.
Enabling UDP checksums can require source or special object modules on some
hosts (Sun & Solbourne at least), or can be as simple as patching a single
location in the kernel (Ultrix, Encore, others).
If my experience is any guide, the PC will be simple to configure, and
everything will work fine once you figure out the proper magic invocations
on the host. Of course, this last may be hard to do - I still don't know
why 'slattach' rejects one of our dialups because it can't do the 'set line
discipline' ioctl(). Such is life in the innards of Unix...

Quoth jbvb@ftp.com (in <9009222311.AA21050@ftp.com>): #If my experience is any guide, the PC will be simple to configure, and #everything will work fine [...] Fine, but s-l-o-w-l-y. RPC tends to be a relative poor match for low speed networks. I remember an incident during the early in-house SQA of PC-NFS SLIP, over a 9600 baud link. A neophyte SQA person complained that it was taking an inordinate length of time to run a particular test - loading WordPerfect from the net. I pointed out that 9600 baud is three orders of magnitude slower than the Ethernet he was used to, and that people don't often encounter 1000:1 ratios in everyday life. [Imagine walking 1000 times faster than usual, or typing 1000 times slower!] We redesigned the tests! (Mind you, Word Perfect did indeed load - eventually.......)
