Trying to tar a directory and transfer it to my AT&T 7300 (SVR2 unix).
Tar -tf works fine on the Mac OSX, but when I copy it over the Unix (not
gnu) tar gives me a:
Tar: blocksize = 20
directory checksum error
When I try to tar -tf the file. Which usually means the block size is off.
Any way I can check to see what the block size is on a modern system
(like a Mac)? tar -tvf doesn't seem to tell me.
Thanks!

I suspect the differences between the tar on OSX and SysV R2 are between
non-trivial and significant.
There /may/ be some command line options that you can add to tar on OSX
to make something that SysV R2 will read.
Maybe someone else here knows the answer. If not, I'd re-ask your
question on the TUHS mailing list where there are more people who will
probably know the command options nearly off the tip of their fingers.

All tar files are the same... except when they are different.
MacOS uses libarchive tar. This version of tar creates the most modern tar
files from the
mid 90s.
However, System V r2 pre-dates that. There's a lot of different tar
formats, that are almost
the same. I'm guessing that --format pax might work, but it might not.
--format ustar like is
the most interchangeable format, and will likely work. It's the
least-restrictive format that
will most likely work. --format v7 will almost certainly work, but has more
restrictions that
might run into, most likely its inability to use anything except numeric
IDs.

Figured it out, the file is actually in CPIO format. Apparently modern
TAR tools can spot this and output the files transparently.
Now to figure out how to make this AT&T 7300 Ethernet card work. It's
installed in the leftmost slot (as seen from the back) but doesn't seem
to be recognized by the driver. Wonder if there is a big manual for it
somewhere in the world.
Hey, anyone got a 7300 with Ethernet working?

Answer: Kermit!!!
Sadly, I no longer have any of my 7300/3B1's. Miss them badly.
I do still have a source set for the OS laying around somewhere, though.

Answer: Kermit!!!
Kermit works, as does the three serial ports, which is how I got the
ETHERNET+IN file up there. Amazing to use, compressing the file on my
Mac takes well under a second, decompressing it on the 7300 takes a
minute or two....
But as Dire Straits said: I want my TCP......

It's such an odd duck, even more so than the NeXT. Still, it has a great
keyboard and if it can do NFS I could hook it up to my SAN.

I may want to borrow that from you. I've got the manuals, time to see
what they say about testing expansion cards....

I question the version of NFS it might do as opposed to what the SAN
supports. I'm guessing that the SAN supports NFSv3 and / or NFSv4. I
wouldn't hold my breath for the SAN to support older versions of NFS.

Doesn't have NFS, in fact I don't quite know if it has a resolver
period. However it does have rcp, so we have that going for us.... :-)
Just have to figure out how to make it work.
