my guess is that this would do perverse things to round-trip estimators,
and that you'd have tcp implementations getting confused about just how
fast and how congested the link was.  e.g. the acks would come back "too
fast" and overly encourage the production of new big packets to clog the link.

you'd want to try it out to see, of course, but i suspect that in general
you'll have better results if you skew performance on a per-connection
basis rather than a per-packet basis.

Originator: ckaul@squirrel.cs.sandia.gov
Organization: Sandia National Laboratories, Albuquerque, NM

I am finally getting around to try and install PPP at our site here.
I have picked up (from merit.edu) ppp-sunos4.1.pl6.tar.  I am having
quite a few of problems with this.

The setup here is the squirrel is a Sun Sparc 2 running SunOS 4.1.1 (work)
and chipmunk is a Sun IPC running Sunos 4.1.1 (home).

I followed the instructions in Readme.streams in terms of installing
files and regen'ing the kernel.  I even see the ppp0 interface when
I have the 'init ppp_attach' keywords on the config file.

The problem occurs when I try and run ppp to start the server.
    squirrel# ./ppp debug squirrel:chipmunk
    popped stream module : ttcompat
    popped stream module : ldterm
    ppp: ioctl(I_PUSH, ppp_async)=22 : Invalid argument
    str_restore: pushed module ldterm
    str_restore: pushed module ttcompat
    squirrel#
(The 22 in the value of errno = EINVAL).

I did go in and modify /sys/sun/str_conf.c from what the documentation has.
from< #if     NPPP > 0
    <     { "pppif", &ppp_ifinfo },
    <     { "pppasync", &ppp_asyncinfo },
    < #endif
to  > #if     NPPP > 0
    >     { "ppp_if", &ppp_ifinfo },
    >     { "ppp_async", &ppp_asyncinfo },
    > #endif
This was based on the fact that /sys/os/ppp_if.c and /sys/os/ppp_async.c
have their module names defined as "ppp_if" and "ppp_async" respectively.
I also changed ppp.c to install ppp_if/ppp_async instead of pppif/pppasync.
    <        if(ioctl(fd, I_PUSH, "pppasync") < 0) {
    >        if(ioctl(fd, I_PUSH, "ppp_async") < 0) {
and
    <        if(ioctl(fd, I_PUSH, "pppif") < 0) {
    >        if(ioctl(fd, I_PUSH, "ppp_if") < 0) {
I still get the above error message after these changes.

I have now gone through the above files again, and replaced all instances of
ppp_if/ppp_async to pppif/pppasync.  This was based on someone's suggested
that kernel modules may not be able to have underscores in their names.
I still get the same error message as above.

Any ideas as to how to fix this?  Any help would be appreciated.

But you just can't expect much at 2400.  How many hours would you need

the price of a capable modem?  Not many, I suspect.

the pcnfsd man page talks about WTMP, the questions are


1.  if built with this option does that mean that "who" should report back 
logged on machines?

2.  the common.h file says that "WTMP" should be added to the CDEFS 
section of the make file.  the makefile has no reference to CDEFS in the 
makefile, what is the story.

3.  if I can ever get a make to build with WTMP, is a kill -9 and a restart 
sufficient to start logging pcnfs logins.

 Can a client do a Kerberized mount to one server and a regular

I've generally observed that Email solves problems better because
it gets answerred when people have time, when they are not interrupted,
and gives them a chance to think or to pass it on to someone else. 
It also gives you a permanent record, something which you may refer
to later when the problem arises.

I have obtained the ETHERSLIP.COM driver and read the info.  Is it only
possible to use it via hardwired connections?  I need to setup a dialup
SLIP with PC-NFS at rates faster than the supported 9600 baud.  I do not
see how the PC-NFS "connect" command will work using the ETHERSLIP.COM.
Is there a "manual" procedure that will allow PC-NFS to connect up and
start a SLIP connection with ETHERSLIP.COM via dialup?


If anyone has done this or something similar, I would appreciate some
advice.  I have been able to a dial-up SLIP working with the supplied
src included with PC-NFS 4.0 at 9600 baud.  However, it seems that
the sunslip program has some problems, at least on my SUN 386i.  I
worked around the problem and can usually get connected, but not always.

The little that I have experimented with it has convinced me that I
should try to get a faster connection if possible.  I have two 9600
baud 4-1 compression modems, so I should theoretically get up to about
38400 baud if the PC serial port can handle it.

We would need source modifications and makefiles so we can taylor
to our environment.  
------------------------
Sun - if you are listening please take note to the following.

Please invest in PCNFSD development, or turn it over to
the PC based NFS product vendors to create a standard.
If you do not have the resources, then pay someone to do it.

Keep a repository of changes, modifications, and versions
like they do for Kermit.  Make this available to all.
Source must compile, Period.  Otherwise the end user sees
your product as non-functional.

It is very hard for end users to get software modifications
from many vendors.  If we are to use PCNFSD then you must make
it available as part of the LAN solution.  Otherwise drop out
and let someone else do it.

Make less assumptions about your end users. Not all are going to
be using Sun's or even BSD type machines for that fact.  YP is not
always in good shape and many of us do not use it anyway.  Many of
your customers see the PC-NFS solution tied to needing a Sun server.
This should not be the case.  PC-NFS should be an open systems product.
If Sun does not think this way then it easily becomes the challenge
for the other PC based NFS products to take on.  We need server
based authentification, printing, and other services, PCNFSD 
is part of the puzzle.

More caveats. B&W was able to emulate our old socket interface by, I
believe, patching the executable at run time, replacing the first few
bytes of each of our routines with a jump to an equivalent B&W
procedure.  However I don't believe that they can handle applications
written using versions 2.0 or 4.0 of the PC-NFS Programmers ToolKit,
since applications linked with these libraries invoke socket, XTI, and
name service primitives in our RTM and RNM modules. (Even "pure socket"
applications still invoke XTI mechanisms for certain operations.) And
I'm pretty sure that B&W doesn't support XTI or netdir.... Granted,
there are a number of apps around which still use the old interface
(which still works), but all of the interesting apps - especially those
using Windows - are written to PTK 4.0.
