   Surely you're not serious.  The ppp folks provided an escape
   mechanism for characters that can't be sent transparently, then
   limited the scope of that mechanism?  That seems seriously stupid
   to me.  What could they possibly have been thinking?

The escaping mechanism isn't limited, only the negotiation mechanism.

Since the initial asyncmap is 32 "1" bits for guaranteed transparency,
LCP negotiations (including negotiations regarding the eventual
operational asyncmaps) progress with all the async control characters
escaped into two-byte pairs, each consisting of a 0x7D flag followed
by a byte that's the original byte XOR'd with 0x20.  Each byte of any
resulting escaped pair is thus outside the range of the asyncmap.

If the initial asyncmap were 256 "1" bits, what byte range would you
use for negotiations?  Everything would need to be escaped, but even
those escaped results would need to be escaped before transmission.
What would they transform into?  If you wanted to leave some
"printable" characters out of the 256-bit wide all-ones initial
asyncmap so that they'd be available for negotiation, how would you
know which ones to leave out, without first negotiating them somehow?

Only the negotiation mechanism is so limited, but the escaping
mechanism can be used on (almost) any character without in-band
negotiation.  This breaks the general philosophy of "no a-priori
configuration", but no good general solution has been proposed, and
this workaround is at least pragmatic, though ugly.

(Actually, the escaping mechanism is also limited, but not as badly as
the negotiation mechanism.  You can't escape 0x5E, 0x7D or 0x7E
because their XOR-with-0x20 results would collide with PPP's HDLC
framing character, the escape leadin, and with each other, resulting
in unresolvable ambiguities.)

I have finally managed to get a PPP implementation for Esix 4.0.3a and
am now in the midst of configuring it.  My question is, "Can I connect
one machine on one network, say 183.100.1.1 to another machine on
another network, say 142.49.1.18; or must both machines be one the same
network?"

Furthermore, if I can't connect two networks together via PPP straight
out of the box, is there someway that i can configure it so that it will
work?  It would be terribly inconvenient to have to change network
numbers just so i can PPP from one host to another... (:-(

I use ppp-sparc4.1.1 and I like it a lot.  I have a Telebit t2500 talking 
to a t3000 hooked to a Telebit Netblazer (Dialup Router).

You can use NFS over the link.  It is slow and you do have to "tune it."
In my application (SS1+ t2500 - t3000 Netblazer), I had to tune NFS
like this:
host:/home /home nfs rw,hard,rsize=4096,wsize=4096,timeo=150 0 0

The timeout of 15 seconds and the reduced read size/write size make it
usable to a degree (~1.3-1.6Kbytes/second compared to 1.8Kbytes/s for
rcp -- a limitation of the 19.2Kbps I locked the serial port to).  I had
to do things via NFS since I have a data file on the host that controls
an application I use.  It works well, considering the slow speed.  As far
as tunign NFS for the slow links, I would highly recommend the O'Reilly
book "Managing NFS and NIS."  It has a performance section which 
helps immensely.

Obviously, the initial negotiation should be done using nothing but 7-bit

send 7f or ff transparently!

Ok, I have looked at several questions posted along these lines and thought
I would ask one myself to summarize.

I would like all infomration on PPP for dos machines. I know ka9q exists,
but I would like a packet driver that I can use with other software. I have
looked at a ppp packet driver from merit.edu, but it seems to be setup to
log into merit nodes, not a general ppp setup.
I want to run Desqview X over my 19.2 Kbaud serial line for a few
applications.

On another note, which of the freeware ( I think that is as close to a

I am setting up PPP for several of our professors here, and would like to

Sure, no problem.  Just tell your PPP link about each end's IP
address.  None of the addresses are related to any other IP address in
either your address space of that of your peer.  Each IP interface is
independent of any others on the same machine, so it can use the same
address as some other interface, different addresses in the same
subnet, different addresses in the same network, or something you've
pulled out of thin air.

For example, our link to the world looks like

		inet 137.175.1.1 --> 38.146.20.1 netmask ffff0000 
The netmask is incidental and ignored.

We occasionally see a similar thing - first our environment & then the 
conditions of failure:

Environment:
	8 Spark (1, 1+, 2 & 10) pcnfsd servers
	3 Harris Night Hawk pcnfsd servers
	50+ PCs w/pc-nfs

If one of the Harris machines answered the request for authentication, no 
problem (ever).  If one of the SUNs answered, then a user would run into 
difficulty (not authenticate) ONLY IF a machine on the sub-net was down.

For some reason when one of the machines on our sub-net goes down, all SUNs 
will slow down (network timeouts?) to the point that the user authentication 
fails.

told me that rembak, the program that is responsable for actually sending

for every job. So, after x number of jobs have been sent, the pc print
server have run out of sockets. Prior to installing the new software,
our print server was locking up 2 or 3 times a day. We installed the software
first thing yesterday, and have not had any problems since. 

I would like to thank Curt Finch at IBM for explaining more about how 
the printing is working and correcting my train of thought, and the

The version of pcnfslpd.exe that we are currently running is 4.1.a3 and

#I'm seeing a problem where a PCNFS V4 client sends an NLM_SHARE request
#to a unix server.  
#
#The server sends the GRANTED message back to the PC, but locks on the
#server to this file are still happening.
#
#In other words, the PC and the server both have the file simultaneously
#locked.

Not true. A sharing reservation is not a lock.

#That doesn't make sense does it?

NLM_SHARE requests allow DOS clients to coordinate the opening of
files in a manner which is consistent with DOS semantics. However,
Unix and other OS's have no such concept as sharing mode, so
they can't play. It's not feasible to map sharing onto locks
(though you're welcome to bash your head against that wall :-)
nor is it possible to force all locking requests to check for
possible conflicts with DOS sharing (since local locks are not
visible to the NLM).
