Yes, you can, top get to the second dump,. you can use forward-space-file mt -f fsf but this is horribly slow. You actually need the new DDS stuff with fast-seek which we believe is in 4.1.

I'm using Ultrix 4.0 on a DS5000 serving (hopefully) 3 DS2100's. We don't want to be upstaged by VMS, do we ? 8) Yes you can, you need to fool 'setld' but it's a bit complex to put here. (I have got a more efficient method than this, but it's a horrible hack) Simply follow the installation procedure as if you were gonna make a separate /usr area for the clients. When you have got it working, then edit the /etc/fstab to pull the REAL (server) /usr on each of the clients. At this point, you can delete the temporary /usr. Helps if your server is the same sort of thing as your client (we have 5830's serving 2100's. We have to check the files for UWS are all there. The 5830's differ by only *4* files from the UWS distribution. Just find them (do a recursive 'diff' against the temporary /usr) - needle in haystack job) alec -- JANET aem@uk.ac.aber INET: aem@cs.aber.ac.uk or aem@aber.ac.uk UUCP: ...!mcsun!ukc!aber-cs!aem ARPA: aem%uk.ac.aber.cs@nsfnet-relay.ac.uk,aem%uk.ac.aber@nsfnet-relay.ac.uk BITNET: SNAIL: Alec Muffett, Computer Unit, Llandinam Building, UCW Campus, Aberystwyth, UK, SY23 3DB
