Subject: Two (or more) terminals one process
Date: Sun, 20 Dec 1992 00:02:27 GMT
Organization: University of Missouri - Rolla

Is there a way that two people can be at different terminals and
working on the same program?  For example, say one person is
in Chicago and has a problem with a makefile.  He calls the sys admin
(me in  stlouis) and asks that I take a look at it.  What would be ideal is 
for the person in Chicago to bring up the Makefile at the same time that
I bring it up (probably using 'vi').  The catch to this is that 
we are not working on copies of the same makfile, but instead when 
I hit the control keys ( like move up,down left, right, or make a change)
the person in Chicago sees the changes take place at the same time
I make them (he also sees the cursor move around...).  The reverse 
would also apply, i.e, when he makes changes I see the same.

	I guess this question applies to two situtations:

		1) When both parties are logged into workstation (running X windows).

		2) When one party (or both) only have simple terminal caps like
			when logging in via modem.

Well, Considering that I do this sort of stuff every week (Or so it 
seems...) here's what I do...

cd from_dir
tar -cf - |(cd target_dir; tar -xfBp -)

or...

rsh from_machine
cd from_dir
tar -cf - |rsh target_machine "(cd target_dir; tar -xfBp -)"

Their are two things to remember though:
1) core files grow because of tar  (They are "holey" files.)
2) device files/pipes do not get copied.

On the other hand, if my users lose a pipe, it's no big deal.
They don't typically keep core files around.
They don't have device files in their directories either.

- The subject says it all.  "How do you back up a terabyte?"

With great care.

- And while I'm at it, how do you fsck at terabyte?

  (1) Write an operating system that handles terabyte big file systems

  (2) The fsck then is easy, as it comes with the operating system :-)

Seriously, the biggest unix file system I know of is efs (on CDC and Silicon
Graphics systems), and that handles 8 Gigabyte filesystems. So for a terabyte 
you need 128 filesystems, which may not be so convenient - you may actually
run out of mount points.

Finally, with data setss of that size you will have to abandon single
backups and look for an archiving and file migration system. Masstor is
a name that comes to mind.

- And does anyone remember the real reason why dump/tar/cpio is not 
- a good thing on an acitve filesystem?

Because users may change files while they are being backed up, and you may
end up with an inconsistent copy on the tape - say a random access file is 
keeping pointers to records at its end, and the data at the beginning.

When a process updates a pointer at the end, the data being pointed to may 
well be already good in the file, but there was still old data at that 
pointed to place when the beginning was read by the backer upper.

Folks;

I've never know email could be such a big issue/problem in my freaking
life!  I know a few months ago there was a thread on which cross-platform
mail solutions are recommended.  At the time I had no use for such information.
Now I do.

We are looking for a cross-platform mail solution that works well in Unix,
Mac and PC worlds.  We would like to administer and serve the mail functions
from a Unix host with the PCs, Macs and other Unix boxes acting as clients.
Besides the usual features, we need a built-in network calendar tool,
remote (dial-in) access, single Unix server to multiple platforms, ability
to send binary files (byte-for-byte), maintenance utilities that run on Unix
host, etc., etc., etc.

We looked briefly at cc:Mail and found it not to be a viable alternative
for a variety of reasons.  I just got off the phone with the WordPerfect
people talking about their WordPerfect Office product and was not overwhelmed.

Anybody got any ideas.  Oh yeah, the most important thing is that the
system MUST run over TCP/IP on all platforms.  No localtalk stuff for Macs,
etc.

As I have done my share of wiring thinnet I have to put in my 2 cents
worth.  Go for the solidcore wire since it is nicer to work with
then the braided.  You would have to bean on the solidcore wire pretty
good to get it to cause problems for you (I know this since the wiring
that I've installed gets abused by those pesky grad students :-)

As for the connectors, don't use the twict one one, get the crimp ones.
These work very well and if done right the first time won't cause you
a bit of problems.

If you are using lpr/lpd, turn off the banner page in /etc/printcap.
Check the manpage for printcap, lpd, etc for more info.  

If you are using lp, modify the script in the model directory to
supress the banner.  There could also be an option for it already.

Or your could move the printer to the Unix box :-)

I always use -p option to the second tar, so that permissions and
ownerships are set correctly.  According to the man page, not using the
-p option will cause the files to be restored with the current umask,
and setUID and stickey information are also preserved.

Note: the -p is only necessary on the extract, not on the corrosponding
create (the man page sez it is only useful with the -x option.)

The above info was taken from a Sun OS, your milage may vary.

I keep a spare partition which is greater than or equal in size than all
other partitions.  All dumped partitions are meta devices.  If they are
not shadowed full time, a shadow is attached.  If they are shadowed, I
attach an extra shadow (detaching one of the shadows to dump would lose
shadowing during the dump, obviously).

This is for a Sun 690 with Online:DiskSuite.  Note that for some reason
you can't lock the root partition to ease the detachment.  This
mechanism allows me to take clean, consistant, fsck'd dumps of running
file systems, including the root partition.

    system ("/usr/etc/metattach $system $meta") && 
	&mail_and_die("can't attach metadevice");
    if ($fs eq '/') {
	$det_status = system ("/usr/etc/metadetach $system $meta");
    } else {
	system ("/usr/etc/lockfs -w -c 'locking for dump' $fs") &&

I recently compared about 6 of these devices and decided on the
Microplex.  It is a little cheaper than the Milan (which came in
second), but is not as fast.  The deciding factor was that the TCP/IP
support  on the Microplex was FAR SUPERIOR than the Milan.  The Milan 
balances that with support for other LANs; Microplex only supports TCP/IP. 
We only needed TCP/IP.  One other point, the Milan offers 1 parallel
and 1 serial; the Microplex offer 1 parallel and 2 serial.
 
Note the speed advantage of the Milan was approx. 7%.

Dear All,
	
I have a problem, and Its pretty urgent (aren't they all).
(So I've cross posted, sorry: comp.sys.misc comp.sys.sun.adm "".misc

The problem is with a sun4 IPC running SunOS 4.1.1 (BSD 4.3).
During boot up it comes up with an mbufs map full error... this appears
to cause general IO fails due to lack of memory.

Firstly the kernal is unaltered .... and theirs plenty disk space on / /usr
etc...

so why has the error occured and what will stop it and thus allow the
machine to boot up correctly... (it fails on rc.local due to memory problems).

Right, but if you have to go that far, it means your utmp file is *not*
