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. ant V ant "I killed Laura Palmer" \o/ ant@brolga.cc.uq.oz.au -O- Anthony Murdoch Prentice Centre /0\ Phone (07) 36 54078 University of Qld

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. -- Bob rbn@epavax.rtpnc.epa.gov Unisys/EPA

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 > TCP/IP over LAN manager ? 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. > 4> Does LAN manager provide file services to UNIX boxes via NFS or does > it implement its own protocol ?

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

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.

A SUN3/180 was being used as the server [not in my department]; I belive it was the fastest machine SUN made at the time. Ok, you can set retries to infinity, but that is ok for running overnight.

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.

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. Mikael Wahlgren d9mikael@dtek.chalmers.se

TCP/IP > and LanMan can run concurrently over the same network (both CSMA/CD). 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. > >4> Does LAN manager provide file services to UNIX boxes via NFS or does > > it implement its own protocol ?

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. > >5> How does the allocation of resources work ?

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.

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.

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. -- John Robert Breeden, jbreeden@netcom.com, apple!netcom!jbreeden, ATTMAIL:!jbreeden ------------------------------------------------------------------- "The nice thing about standards is that you have so many to choose from.

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. thanks -- Jim Sanchez jim@hls.com Hughes LAN Systems - Bellevue, WA (206)646-4999
