No warnings across NFS. You suddenly just can't create files any more
or files are blown away weh you try to append to them. Kindo can reak

HP 9000/847, running HPUX 8.02.

Our machine crashes from time to time, and during reboot we virtually
always see messages of the form

/dev/rroot: INCORRECT BLOCK COUNT INODE = 12345 (8 MUST BE 0) (CORRECTED)

We assume this comes from fsck doing its job, but what exactly does
'8 must be 0' mean?  Eight blocks, presumably, but why should there
be zero of them?

On a related note, is '/dev/rroot' a standard UNIX thing, or an HP
thing?  lssf gives:

# lssf /dev/dsk/c3d0s10
disc3 lu 3 section 10 address 52.6.0 /dev/dsk/c3d0s10
# lssf /dev/root
disc3 lu 3 section 10 address 52.6.0 /dev/rroot
# lssf /dev/rroot
disc3 lu 3 section 10 address 52.6.0 /dev/rroot

It appears that /dev/root and /dev/rroot are special links to the
disk partition with the root file system.  Why do both of these
exist?  Could they ever be different?  Who uses them?

Thanks in advance,

Organization: Institute of Industrial Science, University of tokyo.

I will soon be administrating three networked SPARC stations, and they
appear to be running fine now without any maintainance.  However, the
three disks (.5 G, .5 G, and 1.2 G) contain siginficant amounts of
redundant source and executable code, which I would like to streamline.  I
plan to put most /usr/local type code on one of the .5 G machines, and the
users on the 1.2 G machine.  The current setup is a mess of weird
directories and links, so I think that rather than link some more, maybe I
should start from scratch.

I realize that this would take recompilation of quite a few packages, and
I realize that you shouldn't try to fix what isn't broken.  However, there
are only three or four users total, and they are very forgiving, so I am
going to give it a try.

What should I read?  What is a good directory organization for a
three-workstation network?

TIA,

Thanks SUN!!!!

If I want to OR the day-of-month and day-of-week fields, I could make two
cron entries.  (If cron uses the "AND" method.)

But with the "OR" method, I have to use a bass-ackwords wayof getting the
ANDing of the two fields.

It seems stupid to OR two of the fields then AND that result with the
rest of the fields.  Why not just AND all of the fields???  Can someone
out there in sun.com land answer that one?

I suspect that there are more people who have meetings on the first
Wednesday of the month than there are people who have meetings on the
first 7 days of the month AND every Wednesday.

Sorry about the confusion - I interpreted it as "and I've tried every

Hi,

Mail coming in to progress.com is fine, but I have tried a million combos
to add an MX for *.progress.com only to have it fail for all mail. Any 
hints as to where the MX should go or if this whole file is incorrect would
be greatly appreciated. I have read the SUN, HP, Sequent manuals to no avail.
The set up is a SPARC (pscgate) as name server for the entire progress.com
domain with no others subdomains. All mail is handled by the name server
system pscgate and handed off to the system progress which is a non-DNS
system.

Thanks in advance.

I think what Martin is saying is that the person in question "must
have access to the root passwd".

You can't stop root from editing /etc/passwd, unless you delete it,
and I wouldn't recommend this.

I think you need to re-evaluate the need for this person to have root
access.

	O.K.  I guess I didn't do my research and should have asked a more
pointed question.  Sorry about that.  I notice that there seems that
one doesn't exist.  (and running a daemon with RFC 931 is out of the
question because it assumes that the other side has it too)  Having a
daemon on the other side that recognizes a loop during a finger would 
also satisfy the "back".  Oh well... no wonder Spock is "In search of.."

I am administering a network of three Sparcstation II's.  Disk: .5GB, .5GB, 1.2GB.
I just installed Depot, and the README contained the following lines:

"AFS sites should define USE_FSINFO. Sites without AFS should comment out the 
 starting with AFSLIBS, AFSCFLAGS, AFSOBJ." [sic]

I used archie.mcgill.ca to search for any programs called AFS or afs, and
came up with a lot of nothing that looked like a software package related
to Depot.

There were some files in the distribution called AndrewFileSystem.*, and I
guess it is not a coincidence that this acronym-izes to AFS.  I did an
archie for [Aa]ndrew, and found a bunch of stuff that seems to be related
to X-windows.  Nothing called AndrewFileSystem or anything like that. 

In any case, Depot compiled fine when I commented out the AFS lines, but I
haven't used it yet---Do I really need AFS?

We're looking for input on a decent Mac with ethernet to Unix file transfer
utility.  At present we're using the gatorbox, but the Appletalk speed is
clearly unsuited for our pruposes, that is transferring large sounds files
from the Mac to our Unix servers.  We have some Macs with Ethernet Cards,
and have tried uShare and InterCon's Mac NFS.  A quick summary of these two:

uShare runs on the Sun 4, and fires up some atp daemons that allow the Macs
on Ethernet to mount Unix disks.  However, it seems pretty buggy, prone to
crash and isn't all that easy to configure or use. But it's just one piece
of costly software that runs on the Sun.  

Mac NFS lives on the mac, takes a bit of configuring to get running, but once
in place it seems to work.  However, it's over $200/pop, and that could get
pretty pricey, given the number of Mac at our site.  

Does anybody have any experience with these products or their competitors?
Please email rickk@emu.com, and I'll send a summary out on 9-1-92.  Hurry, 
this is YOUR CHANCE to contribute your wisdom for the good of all.  Your

sudo id great. We use it all of the time. We did notice one small problem
on our system. sudo couldn't be used on scripts, only on binary (object)
files. The way we got around that was to create a small c program that
called the script we wanted to run. We then give sudo access to the c
program, and everything worked great. This also has a side benefit. Just
because we want to give access to some command doesn't mean we want to give
access to all of the options of the command. By creating a c program that
calls the priv command with just the options we want, we have the best of
all worlds.

	I see (said the blind man to the deaf man :-).  I do run a tcp
logger that keeps track of all tcp actions listed in a secondary file
similar to the /etc/services (on my Sun) keystroke-for-keystroke with
real time simulation on playback.  I do this because it seems that one
machine (not on my floor or under my administration - thank the Lord)
has been compromised by a few.  Sloppy on their part.  Keeping a list
of people who finger and try to randomly telnet in or whatever helps
me stay on top of things.  This is the reason for wanting to know who
fingers.  "Who" is the info I'm after - not just the site.  Altho' the
security people were notified because we are a gov't agency, I feel
a little prevention goes a longer way than reparations.
	I do see the advantage to the rfc931 and I am looking into it.
> he's just being a little cruel.
	I can deal with cruelty - no prob.  It seems sometimes that's 
what it takes to get an idea through when tact is at a minimum.  Thanks
for the feedback folks...

	And BTW, me as a sys admin is by default - not by choice.  I'm
into embedded control systems using microcontrollers.  A bit detached
from the UNIX network world, don't you think?

Look into SLIP (Serial Line Interface Protocol) for your particular

>root password.

 Why does this user need to know the root password?

 A possible workaround would be to implement the 'sudo' command as described
in 'The Unix System Administration Handbook' by Nemeth, Snyder, Seebass
Prentice-Hall, 1989.

 This will let you give the user the ability only to execute selected
root privileged commands.

The password routines on machine that are able to run NIS use the
entry `+::0:0:::' to indicate ``and now look in the NIS map''.

The username, uid and gid are always taken from the NIS map. If the password
entry for + has any of the other fields set, it uses those values
instead. E.g..

+:*:0:0:::    		 -- everyone from NIS has password ``*''
+::0:0:::/etc/noshell    -- everyone from NIS has shell ``/etc/noshell'',
                            (useful on file servers)

There are also entries of the form:

+@netgroup::0:0::: and +user::0:0:::
