- Andres Molnar is looking for a cheap and not buggy TCP/IP for VMS for
- educational institution use.
-
- I don't know about cheap but I do know good. We use TGV Multinet on one
- of our vaxen. This product provides the basic transports, talk, mail,
- telnet, rlogin, rmt, lpd, ftp, and a few other things. It works like they
- say and installs without problems. We also use TGV NFS server. It does
- the best of those looked at by ABB Windsor Conneticut USA area facilities.
- The TGV product can also transport X-11 over TCP/IP. It is possible to
- have Sun4 machines be x servers for VMS clients and vice-versa.
-
- NAS-250 provides the transports, socket library, mail, telnet, X-11
- transport and ftp. It does not currently provide rmt or lpd services.
-
- The multinet machine is a VS 4000-60 which can run NAS-250. The multinet
- offering is much more complete and much better documented. TGV provides
- excellent manuals with good content. They look genuine DIGITAL but seem
- to better meet our needs than the DEC manuals do. NAS came with BOOKREADER
- manuals which differ in content and appearance from standard DEC printed
- manuals and cannot be printed.
-
- The TGV NFS facility appears superior to that of NAS-250. The Multinet NFS
- server allows any limb of a VMS file system to be exported and mounted
- on other NFS clients. It goes to great lengths to make text files work.
- We use Sun4 machines to manipulate VMS program text routinely. For
- technical reasons having to do with VMS text file formats, the server is
- slower than similar UNIX NFS servers. The server also seems to take
- longer to respond to directory querries than the SunOS NFS server on
- machines of similar performance (SS 4/330). We are unsure of the cause.
-
- Heavy use of the NFS appears to interact with VMS MSCP service. A really
- brutal grep will cause our NI cluster to loose quorum, come apart and
- reform. This can happen several times a day. We've not investigated
- this problem because things usually recover in a minute or two and we
- hope planned facility changes will help. The VAXen currently hear all
- of the traffic on our thin net (20 nodes sun and Vaxen).
-
- NAS NFS appears designed to allow a VMS machine to provide a UFS for
- Ultrix clients. A container file has a UNIX file system built inside
- it. To change from VMS to NFS worlds requires using a pair of copy
- commands provided with the NAS package. I don't believe that NAS NFS
- can be used in the true peer-to-peer spirit of NFS to the extent
- that the Multinet product can.
-
- Multinet is $1000 for a desktop vax and $3000 for a deskside vax. They
- may have educational discounts and volume discounts. $1000 is two days
- work at my labor rate. Not a bad buy.
-
- TGV is a class act. They do this one little thing excellently well with
- style!
