Troff, eqn, tbl, etc

by Will Senn

In the help file for v6 (/usr/doc/hel), it says that troff, eqn, etc are not part of the distro and even though there are man pages, the utils are not present in my base v6 install. I know this because I copied the hel0-hel5 files and naa over to my mac and used groff to make ps files and ps2pdf to turn those files into pdfs. While they came out ok, there was some overlapping text and the math equations were imperfect. I figured if I could do more preprocessing in v6 before moving files into mac, they might come out better, but the utils as noted above. Do we have the utils as bits somewhere (or is this an oblique reference to 1bsd)? Thanks, Will Sent from my iPhone

V6 intro file display in terminal

by Will Senn

There is a file, intro, in /usr/doc/man/man0, that is a system introduction prepared for a ‘Graphic System phototypesetter... in troff’. I was wondering if there was a way to display the file in v6 on the terminal, similar to displaying man pages: nroff /usr/doc/man/man0/naa /usr/doc/man/man1/write.1 I couldn’t find a troff command and the output from various nroff incantations were less readable than cat. Thanks, Will

There's no ranlib in v6 :-) Cheers, Warren

I wonder how that one slipped through? Looking at 'run', it really does look like it was used to prepare the systems on the distribution tape. So probably the libraries just happened to already hold the latest and greatest, so that error had no effect. The thing with needing to order the library contents properly to cause all the modules to get loaded is, I reckon, the reason why 'ar' has those arguments to specify where in the archive a given file goes.

Deleted lib1 and lib2 in v6, recoverable?

by Will Senn

So... I whacked /usr/sys/lib1 and lib2 ‘accidentally’ meaning I logged in as bin changed to /usr/sys and typed rm lib1 and rm lib2 :). Now, I was thinking at the time that I could regenerate them... this seems like a possibility, but I can’t seem to get them back. sh run as bin doesn’t do it. So, what magic incantation is required to rebuild them. What motivated the exploration was a desire to modify main.c and see those changes manifest. Help. Thanks, Will Sent from my iPhone

Happy birthday, John von Neumann!

by Dave Horsfall

We gained John von Neumann on this day in 1903, and if you haven't heard of him then you are barely human... As computer science goes, he's right up there with Alan Turing. There is speculation that he knew of Babbage's work; see https://cstheory.stackexchange.com/questions/10828/the-relation-between-bab… . -- Dave

NFS & Kerberos woes...

by Grant Taylor

Do any fellow TUHS subscribers have any experience with NFS, particularly in combination with Kerberos authentication? I'm messing with something that is making me think that Kerberos authentication (sec=krb5{,i,p}) usurps no_root_squash. Meaning that root can't access files owned by other users with go-rwx. Almost as if no_root_squash wasn't configured on the export. Does anyone have a spare bone that they would be willing to throw my way? -- Grant. . . . unix || die

Re: [TUHS] Usenix: no official Unix 50th celebration, (yet)

by Norman Wilson

I thought I read a different email saying that there will be a track about the 50th anniversary. But cannot find any details or reference to it now. Does anyone have information about Unix 50th celebration(s)? Is it time for paper submissions? ... ==== If you mean for the 2019 USENIX Annual Technical Conference, the CFP is https://www.usenix.org/conference/atc19/call-for-papers The submission deadline is about three weeks away, on 2019-01-10. I see nothing explicit about a UNIX 50th celebration, alas. At least one program-committee member is on this list; perhaps more information will appear. Or there's a contact address for the program co-chairs on the web page cited above. Norman Wilson Toronto ON

Usenix: no official Unix 50th celebration, apparently

by Warren Toomey

Hi all, I've just heard that the Usenix board of directors do not want to explicitly celebrate the 50th anniversary of Unix. It's been suggested that we, the TUHS members, both lobby the board and also offer our assistance to help organisation such a celebration. Who, on the list, would put their hands up to help organising something that coincided with the 2019 Usenix ATC in July 2019? I'd like to get the bare bones of an organising team, then approach the Usenix board, offer our help and ask them to support us. What do you think? 11 months to go. Thanks, Warren P.S. Nokia Bell Labs are also going to organise something, possibly a month earlier but I have no solid details yet.
