NT Services for UNIX first impressions Burkhard Renk

NT Services for UNIX - first impressions Burkhard Renk, Uni Mainz

University of Mainz - IS n n Approximate 30 000 Students Big computer users are: u Economics and laws u Human science u Natural Science F Physics F Geography F Chemistry

General IS organisation n Computer center u HP/Convex Parallel computer u Digital UNIX Server ( 2 x 8400 ) u NT - Server ( Cluster ) u NT Workstation pools ( some 250 ) u UNIX - NT integration with DCE/DFS u Services migrating from DFS(UNIX) to DFS(NT) u Setting up multi user NT ( WTS, Wincenter )

Independent IS in Institutes n Economics, laws, human science: u Migration from (MVS, AS 400, BS 2000, SINIX, …) to NT Servers completed. u NT clients, W 95 clients, MAC clients, few UNIX n Natural science u Move to commercial apps in most fields ( x 86 NT ) u Physics: ( coming from VMS ) F Solid State, Atomic, Nuclear: NT migration done F Theory almost pure LINUX F Particle Physics bound by CERN - compatibility n A general infrastructure has to primarily support NT

University IS Orders in 1998 n n n 665 PCs with NT license 81 Macintosh 39 UNIX Systems (incl. 5 Linux Alphas)

Consequences n n Optimization of services for NT clients Treat UNIX as special client. Available was for download: Microsoft UNIX Services for NT Beta 2 So we downloaded and tried it.

Installation n n Hardware: DEC PW 433 a with WTS Self-extracting and running setup ok First reboot Some fields in a configuration shield for NFS had to be filled out. u As a former VMS and now NT manger, I did not know what they wanted u My UNIX guru didn’t understand either u We made a best try n Next reboot - Click on NFS network

Next Steps n n n Click and wonder what the UNIX people export Set up an export yourself Set up a user mapping u Simple n n interface Tool to see the exports of NFS servers Tool to see RPC configuration of servers

User mapping

Show Mount

Very first tests n n n n NFS server can be used with UNIX clients, measured speed 800 K for real file copy disk to disk over 10 Mb Ethernet. (PW 433 a as NT Server and DUNIX 4. 0 d client ) DUNIX 3. x systems did not understand user mapping? Strange things when accessing objects twice? Did not yet really understand mapping of rights. ( Need for much better documentation ) Speed between 2 NT systems over NFS similar to Netbios over TCP/IP ( 3 MB/s disk to disk over 100 Mb Ethernet ) Password synchronization not tested Telnet server not tested

Conclusion n n It is a Beta version It is working and performance looks promising Better documentation needed Is worth to be looked at carefully when released.
