Under LAN Manager, can a DOS workstation act as a server to the Net? Or can DOS stations only be clients? Thanks, Will (sun!portal!cup.portal.com!Will)

There's two answers to your question. The question is "Can msdos-based servers serve file requests from lan manager based clients?" The answer to that one is yes. You can set up a network of msdos based servers and have them serve requests from os/2 or msdos clients. Here's where it gets tricky: You CAN'T do that with DOS lanman. What you need to do is use the server portion of the MsNet product. You can mix and match msnet and lan manager servers and workstations on the same network. Typical example: "I've got a network based on ungermann bass network adapters and their 'net one' networking software. Can I put os/2 lan manager servers or clients on this network? " Yes. Ungermann Bass is a licensee of MsNet, and their "net one' product is compatible with os/2 lan manager. From a "net one" client you can send and recieve file requests or device requests. Same holds true for 3com's 3+share product, at&t's starlan product, and so on. I'm mentioning brand names here for examples, not as endorsement of product. Product Server software Client software ----------------------------------------------------------------------------- Os/2 lan manager Yes Yes Unix Lan Manager Yes No Msdos Lan Manager no Yes Msdos MsNet Yes Yes For information/pricing/availability, the best person to contact is your current network vendor of hardware or software. There ARE some functional differences between the different software packages although they will all work correctly with one another. In particular Product Encrypts Share comm Share Share Passwords Devices Printers files ----------------------------------------------------------------------------- os/2 lan manager server yes yes yes yes unix lan manager server yes yes yes yes msdos MsNet server no no yes yes If you're interested in more detail, we offer classes on lan manager and os/2, down to the device driver level.

Well, actually, I intended my question to be "Can MS-DOS computers act as *application* servers to client programs, where both client and server are running under an unmodified version of LAN manager." So would it be possible to set up an MS-DOS application that accepts named pipe requests from either OS/2 or MS-DOS client programs? Thanks, Will (sun!portal!cup.portal.com!Will)

You can run named pipes between applications as long as the network you are running on top of supports named pipes. All versions of lan manager support named pipes, all versions of os/2 support named pipes. The network product that preceeded lan manager, MsNet, does not support named pipes and so cannot support their use. Synopsis: If you run lan manager, whether it's an os/2 server, an os/2 workstation, or an msdos workstation, you have the ability to support named pipes. If you run MsNet, you cannot use named pipes unless you wrote your own support for it. So if you set up a network consisting of one os/2 server, one os/2 client and one msdos client all running lan manager software (msdos lan manager in the case of the msdos client) you could run named pipes to any of those machines, and everything would work fine. You can add MsNet machines to that network, and they would be compatible with the lan manager systems as far as shared devices and shared files go, but you would not be able to use named pipes to or from them. That answer your question? Bruce King / Microsoft U / (206) 882-8080 / bruceki@microsoft.UUCP

DOS based machines cannot 'Create' named pipes, but can 'open' them. Thus DOS machines can only be clients to a named pipe 'created' on a server. Server operating systems that may 'create' named pipes using either LanManager or a ported version are:- OS/2 - LanManager, Net One, IBM LanServer, 3+Open, Compaq LanMan, etc etc VAX VMS - Dec's have ported LanMan to VMS AT&T Unix - AT&T have ported LanMan to Unix (LM/X, jointly developed by Microsoft and HP is our name for the portable version of LanManager) HP have LM for their Unix flavour. IBM MVS - I've forgotten the name, but someone else has announced they are porting LM to MVS. ... and so the list goes on... The common factor for servers, and 'creation' of named pipes is multi-tasking. DOS cannot wait around in a second task when a client signals an open on a named pipe, so creation makes no sense. Hope this clears things up. Alistair Banks OS/2 ISV Group Microsoft
