[comp.protocols.tcp-ip.ibmpc] LAN MANAGER Questions.

ant@brolga.cc.uq.oz.au (Anthony Murdoch) (05/29/91)

Hi Netters,

Sorry about the cross-posting of this article, but the questions I want to
ask cover the realms of a few news groups and there doesn't appear to be
any general lan newsgroup or and group for MS LAN MANAGER.

We are looking into providing support for a LAN package and I have been
made part of an effort to decide which LAN package would be the best to
support.  We already support DEC's PCSA here to provide PC connectivity
to our VAX's, but we are interested in providing connectivity to our other
machines as well as supporting a true LAN (I don't consider PCSA a true
LAN).

Our first consideration was PC/NFS (again not a true LAN), but I have been
recently given some information on Microsofts LAN Manager and it has my
interest arroused.  But the presentation I have leaves some holes
(questions) that I would like answered before I consider it further.  If
someone out there with LAN manager experience, or possibly even someone
from Microsoft, could answer some of these questions, I would be very
appreciative.

1>  Is it absolutely necessary to have an OS/2 server to run LAN manager ?
    We would prefer to be able to run with our UNIX box (SUN 470) as the
    main server.  This isn't a major point though so if there are a lot of
    other advantages we will run with it :)

2>  Which ethernet cards are supported by LM ?  Or is that, which ethernet
    cards support LM ? :)  Particulary, are any of DEC's ethernet cards
    supported.  We have a large number of DEPCA Turbo ethernet boards (for
    PCSA) and so having support for them would be advantage.

3>  Is there any packages (Comercial/Shareware/Freeware) that provide
    TCP/IP over LAN manager ?

4>  Does LAN manager provide file services to UNIX boxes via NFS or does
    it implement its own protocol ?  I'm not sure which of these would be
    preferable, perhaps you can offer some opinion ?

5>  How does the allocation of resources work ?  Does LM allow any user to
    access any resource on any machine so long as the user has the
    permissions ?  If so, then does this include DOS machines ?  I can see
    it working with an OS/2 machine, but does it allow a DOS machines
    resourses (printers etc) to be accessable by others without
    interupting the user on that DOS machine ?

    Does LM allow access to printers on remote UNIX/VMS machines ?

    The kind of situation that we are looking at initially is where a site
    wants to use our UNIX box for some of its file services, but still be
    able to access its own printers etc.  The site is not technically
    orientated and so they want us to handle ALL server maintenance.  Will
    we be able to keep the server on our site or will there have to be a
    duplicate server (or something) at their site to handle all their
    printers etc ?

6>  How good are the mail facilities ?  Is it possible to send mail
    to/from internet machines ?

7>  Is it possible to connect to the LAN from a terminal ?  How would this
    be set up ?  Is it possible to connect to the LAN through TCP/IP
    (telnet) ?  These are picky questions and not that important :)

8>  What is the availability of sercer/connection software for
	- Sun SPARCservers
	- DEC VMS VAXes
	- IBM VM Mainframes
    Who sells/supports each of these ?

Well, I think that's all the questions I have.  My thanks go in advance to
anyone who is willing to provide me any of the answers I need.

I'm curious.  The original poster on this claimed that PCSA and PC/NFS
aren't "True LAN" implementations.

What are the characteristics of a network client/server/peer architecture
that you believe make it a "True" LAN implementation?

What about these 2 (and others) that you find limiting would have to
be improved on to make them "True"?  What is missing in your opinion?
Which features do they have that others are missing?

One of the most limiting features of most architectures/implementations
that I've been exposed to is the heroic amount of effort required to 
establish "transparent" interoperability with other solutions.

How do you define a true LAN?  A local area network is just as it says,
and PCSA can be the glue that makes it, just as Novell can, etc.

Lan Manager/X, i.e. lan manager for Unix, has either been released or
will be soon.  Don't know which platforms are supported.

Lan Manager is a base from which network programs, such as PCSA, 3+Open,
etc, work from.  The individual software house determines such mundane
issues, but more often than not NDIS drivers are supported, which means
the DEC ethernet boards are okay.

> 3>  Is there any packages (Comercial/Shareware/Freeware) that provide

Again, Lan Man doesn't bother with the details, so PCSA works over DECnet,
IBM might use Token Ring, etc.  Obviously, if you use LM/X then
TCP/IP might be the transport.  Or, you can go for the many public domain
(such as NCSA Telnet) or commercial packages (such as FTP's PC/TCP, etc).
Often, when using NDIS, multiple protocols can be supported on s single
workstation.

Don't know.  I guess NFS is a different ballgame, and would not be supported
by LM.

Yes, provided the server is OS/2 or Unix, etc.

The limitations of DOS doesn't really allow that sort of resource sharing.

PathWORKS for DOS uses LM.  LM/X gives the same functionality on Unix.
See also DEC's PathWORKS for Ultrix.

No.  LanMan has been ported by several vendors to run on UNIX and DOS as well
as OS/2.

It depends on what the vendor decided to support.

Most vendors have some sort of LanMan - TCP gateway available.  TCP/IP
and LanMan can run concurrently over the same network (both CSMA/CD).

LanMan uses ISO/OSI protocols.  Most large network envorionments currently
use TCP/IP but the trend is toward shifting to ISO/OSI (the gov't has
adopted ISO/OSI).

Yes. Yes. Sort of.  RE: the last question -- It can be done but is quirky
sometimes.

If the remote machine is part of the network (don't think VMS is supported
by anyone yet, though).

As far as I know you would net to have some sort of server on their site
for the printers.  I could be wrong though.

Answer to both questions:  It depends on what the vendor provides for a mail
package.  LanMan doesn't have a standardized mail package that I know of.  At
our site we can mail to the Internet and vice-versa.

Not that I know of.  Not really.  It depends on what you mean by "connect to
the LAN".

I have'nt heard of anyone porting LanMan to Any of these machines but maybe
someone has.

If you have anymore questions, feel free to drop me some email.

1. Fileserver efficiency.
      Use of PC-NFS on a non-dedicated server is asking for trouble; a heavy
user of the system will cause DOS clients to time-out producing error messages
on the clients - not very good.
 
2. Workstation efficiency
      Use of PC-NFS or PCSA requires VAST amounts of memory; it may not be a
problem if you high-load the device drivers, but this isn't much use on an
IBM XT with 640k of memory
 
3. Security
Novell offers you a much richer access rights scheme than NFS -
Read
write
Create [New files/directories]
Open   [existing files]
Search [directories]
Execute-Only
 
In addition rights can be set by user and group, not
      The Owner
      His/Her group
      Everyone else
 
Also PC-NFS is stateless, so if you reboot the server users don't
necessarily loose their connection - not very good if you are trying to get
rid of a hacker from your system. PC hardware is often more reliable than
mini-computer hardware (None on my Novell fileservers have crashed over the
past year, I have lost one SUN CPU board, and more pieces of the PRIME's
than I care to remember)
 
4. Remote Booting
Can you remote boot a PC without a hard or a floppy disk using PCSA, or PC-NFS.
[you can with PCSA if you have the right sort of DEC ethernet cards].#
 
   5. Price/Performance
compare the cost of a pc-based fileserver with the cost of a PC-NFS or
PCSA fileserver.
 
-------------------------------------
Basically I think TCP/IP is NOT good for fileserving, but is good for
other things :
      Electronic Mail     (POP, SMTP etc)
      Remote Login        (Telent, though I prefer X.29 as this is Uk.Ac)
 
 
:-) any one disagree ?

    >2>  Which ethernet cards are supported by LM ?

By default, LM for DOS and OS/2 works on any NDIS driver (ask your board
vendor for one).

    >3>  Is there any packages (Comercial/Shareware/Freeware) that provide

Most DOS and OS/2 TCP/IP packages can share the NDIS driver with LM.

    LanMan uses ISO/OSI protocols.

LM uses NETBIOS at the session layer as its network interface.  NETBIOS can
run on TCP/IP, or OSI, or XNS, but most frequently uses LLC2 (ISO logical
link layer, usually called 'netbeui').

Good grief, what are you using as a server? I can run for days at a time
accessing a system that is serving dozens of Suns and PC and is also
running OpenLook (talk about a cycle stealer) without any significant level
of retransmissions. Furthermore if it's really a problem you can always
configure the number of retries before an error is reported - setting it to
0 (infinite) means I can rebuild all of PC-NFS overnight and not worry
if somebody takes down the server for backup.

#2. Workstation efficiency
#      Use of PC-NFS or PCSA requires VAST amounts of memory; it may not be a

I believe that PCSA is on the bloated side, but PC-NFS has always been
around 80K, which is right in the middle of the field when it comes to
size.

#

Yes, we all know Unix needs ACLs. One day.

Most people regard the statelessness as a rather useful attribute,
as I noted above. If you need to eject a hacker, there are more issues
than simply rebooting the server, and more solutions too. (Hint:
try "man fsirand".)
 
#   5. Price/Performance
#compare the cost of a pc-based fileserver with the cost of a PC-NFS or
#PCSA fileserver.

Hmmm. I'll bite. Here's a sample configuration for a server
and software for 10 client PC's:

SPARCstation SLC	4/20FM-8	List	$4,995
 - 12 MIPS
 - 8 MB RAM
 - Mono
 - Diskless
File server option	X2001Z			$9,600
 - 669MB disk
 - 2.3Gbyte 8mm tape
 - 644Mbyte CD ROM drive
SunOS on CD-ROM		SX-21			$  300
PC-NFS Documentation				$   75
PC-NFS RTU, media, no doc at 5-24 discount	$  245 x 10 = $2,450

Total:						$17,420

I could get it cheaper using a 486 clone with a clone SVR4, but
performance would probably be inadequate. Can someone give me the
equivalent for a name-brand NetWare server system. Don't forget to
include all software, the mouse, tape, CD, etc.

#-------------------------------------

#other things :
#      Electronic Mail     (POP, SMTP etc)
#      Remote Login        (Telent, though I prefer X.29 as this is Uk.Ac)

The problem here is the confusion and manageability of maintaining
multiple name spaces, administration spaces, routing structures, etc.
Suppose (hypothetically) that I run NetWare on my PC for file access
and TCP-based stuff for the rest. Oops - we use Unix boxes as routers,
and they won't route IPX, so now I'm limited to my local LAN for file
sharing. What's my PC's name? Is it the same in the TCP/IP and NetWare
worlds? There's a printer on another PC I want to use, which name
should I use? Which stack?  Management wants to manage the net with
SNMP. How does NetWare fit in here?  And so on.

    main server.  This isn't a major point though so if there are a lot of

Answer: AT&T/SCO and Microsoft (plus others!) have a working LAN Manager/X
        which is LAN Manager for Unix.  There are other platforms that LAN 
        Manager is being ported too as well.

2>  Which ethernet cards are supported by LM ?  Or is that, which ethernet
    cards support LM ? :)  Particulary, are any of DEC's ethernet cards
    supported.  We have a large number of DEPCA Turbo ethernet boards (for
    PCSA) and so having support for them would be advantage.
Answer: Any card with an NDIS specification driver will work.  This includes
        some of the DEC cards, 3com, Western Digital, Racal ......

3>  Is there any packages (Comercial/Shareware/Freeware) that provide
    TCP/IP over LAN manager ?
Answer: There are TCP/IP packages for OS/2 (which will co-exist with LAN
        Manager) from IBM, Essex, FTP software etc.  Some have a NetBIOS over
        TCP/IP layer which will then allow you to run LAN Manager ontop of
        TCP/IP.

4>  Does LAN manager provide file services to UNIX boxes via NFS or does
    it implement its own protocol ?  I'm not sure which of these would be
    preferable, perhaps you can offer some opinion ?
Answer: You can use LAN Manager/X Client for Unix to access OS/2 servers or
        you could see if there is an NFS server out from any of the  TCP/IP
        vendors.

5>  How does the allocation of resources work ?  Does LM allow any user to
    access any resource on any machine so long as the user has the
    permissions ?  If so, then does this include DOS machines ?  I can see
    it working with an OS/2 machine, but does it allow a DOS machines
    resourses (printers etc) to be accessable by others without
    interupting the user on that DOS machine ?
Answer: DOS machines can only be clients not servers.

    Does LM allow access to printers on remote UNIX/VMS machines ?
Answer: Not right now but there are people working on that.

    The kind of situation that we are looking at initially is where a site
    wants to use our UNIX box for some of its file services, but still be
    able to access its own printers etc.  The site is not technically
    orientated and so they want us to handle ALL server maintenance.  Will
    we be able to keep the server on our site or will there have to be a
    duplicate server (or something) at their site to handle all their
    printers etc ?

6>  How good are the mail facilities ?  Is it possible to send mail
    to/from internet machines ?
Answer: Microsoft Mail has just been announced and includes gateways to SMTP,
        X.400 etc.

7>  Is it possible to connect to the LAN from a terminal ?  How would this
    be set up ?  Is it possible to connect to the LAN through TCP/IP
    (telnet) ?  These are picky questions and not that important :)
Answer: Not really.

I guess it depends on what you expect out of a LAN.  Things like PCSA and
PCNFS are designed to provide connectivity from you PC to some non-PC (ie
mini or above) computer (ie PCNFS to UNIX host/servers and PCSA to VMS
host/servers)

I see a LAN as something that provides PC-PC connectivity, as well as
PC-(big machine) connectivity.  I guess my ideals are approaching a
distributed network (everyone can access everything).

I have to thank everyone for the answers provided, though one thing
worries me.  Some of the answers have completely different answers.

A SUN3/180 was being used as the server [not in my department]; I belive

You use IPX-IP encapulation, the workstation encapulates the IPX in IP
and sends it through the network. [Lan workplace for DOS]
If you don't want to fork out more money for LAN workplace for DOS
use the local fileserver to encapsulate the IPX in IP for you
Alternatively you reverse the network structure and use NW3.11 fileservers
as the IP and IPX routers.
 
Netware does not 'name' the PC's instead it uses the MAC address, and
'connection' number to identify them so name management is not a problem
in the NetWare domain...
 
The printer is not such a 'heavy' problem. Without a complete map of your
network it would be impossible for me to 'guess' at how you would want to
arrange the printers so here are the components :
Novell's NFS support includes LPD
NW3.xx PrintServer allows printing to pc's attached to workstations.
 
Assuming you already have printers
attached to PC's you carry on using them in the same manner. Novell's NFS
includes a LPD to service printers.
 
Novell include a SNMP agent with the TCP/IP support in NW3.11

Many LM vendors would ship several of the more common NDIS drivers with
their package (e.g. 3Com & HP shipped 3Com drivers, Western Digital drivers,
IBM TR driver, and HP drivers).  Other NDIS drivers would have to be hand
installed into protocol.ini, etc.

HP offers both LAN Mgr OS/2 & LMX over TCP. Ungermann-Bass has LM OS/2 over
a TCP transport.  Later this year Microsoft is expected to offer LM 2.0 over
TCP.

As James says above LAN Mgr can run over many different protocols.  That
does obviously cause interoperability problems.  AT&T is the only vendor
that I know of who is presently shipping a LM product that uses OSI.  DEC in
their new products primarily uses DECNet although they offer some TCP
connection.  Most of the LM OS/2 vendors offer XNS or NetBEUI although UB
has TCP.  HP supports TCP.  Some day the number of protocols out there may
shrink so that interoperability will be easy.

It is possible to connect to an OS/2 full screen session with a terminal,
by using Os2You (shareware).  The solution is to install Os2You on one 
of the servers/requesters on the LAN, and you would be able to connect
to an OS/2 full screen session via async. line (modem or cable).

It works quite like the dial in unix machine I am running now.

Sorry if this showed up repeatedly.  I wasn't aware that the message made it

LanMan Client (and Server) 'talk' to the NDIS driver.  NDIS drivers are 
available almost all e-net boards, even the newer DEC ones.

With NDIS you can run multiple protocols over the same interface.  The setup
I use (which I think works pretty spiffy) is to use Microsofts NetBEUI 
protocol to do LanMan stuff, load and bind the NDIS to Packet driver interface,
and then use packet driver based TCP/IP software (like PC/TCP or CUTCP) to do
TCP/IP kinds of stuff.

Huh?  Actually the modular nature of LanMan allows you to use any one of a
number of protocols.  The ones I know of are NetBEUI, NBP, XNS, and TCP/IP.

LanMan resource serving is done from an OS/2 based system.  For now that means
that your server runs OS/2.  There is third party software available to allow
DOS machines to offer disk and printing resources to the rest of the LanMan 
clients.  In the future if and when clients dump DOS and move to OS/2 then
LanMan can start to look more and more like a peer to peer network because
OS/2 workstations can then act as both a client server.  Could be neat!

Now the real reason I replied to this article (sorry, I always get carried 
away).  I understand that DEC Pathworks 4.0 is based on LanMan 2.0 code.
I think it is not a full LM 2.0 implementation but it has been implied that
if the TCP/IP transport is chosen for both the VMS side and the PC side then
LanMan 2.0 client can connect to VMS Pathworks 4.0 server.  I have not tried
this but would love to hear from anyone who has.  I like the LanMan product
and think for larger LANs it has some strong features.  It should be 
interesting to see how the market responds to LM 2.0 especially the Unix
ports of LM 2.0 which are now showing up.  I wonder if anything can slow
the Novell juggernaut.

Close. Acually DEC's Pathworks supports two different servers. The PathWorks
server for VMS is the same server that they used for PCSA (MS Network over
DECNet), so in that respect PathWorks is the same as PCSA when viewed from
services provided from a VMS/VAX box (MS Network over DECNet - resource
security only, no support for mailslots and named pipes (the 'stuff Lan
Man layers on top of SMB).

DEC also sells PathWorks for OS/2. This IS Lan Man 2.0 with DECnet as a 
transport. It also seems to imply that you could take the PathWorks/OS2
DECNet transport driver (decnet.os2?) and run it on an MS Lan Man server
giving you PathWorks via MS Lan Man (which is prob. the same as DEC's
OS/2 PathWorks - ie: they just repackage MS's Lan Man with a DECNet
transport.

The NDIS driver that DEC ships with PathWorks is an NDIS to DLL driver
(dll.dos & dll.os2). DECnet's transport runs on top of the dll driver.
It also means that you can run the OLD PCSA 'stuff on top of this
driver (PCSA over NDIS). The only gotcha you need to watch out for is
dll.dos and dll.os2 make the "optional" ndis "change hardware address"
call - not all NDIS MAC drivers support it at this time.

This was the state of PathWorks as of Networld Boston and comes from the
DEC engineers.

As an aside to this question, does anyone know if there is an archive
site with NDIS drivers on it?  I am specifically looking for a driver
for the DEC (forget the nomenclature) ethernet card.
