Subject: REALLY ANNOYING BUG in Sun's passwd(1) [Shadowing]
Keywords: bug,passwd,C2,shadow
Organization: Dept. Computer Science, University of Western Australia.
Date: Tue, 15 Sep 1992 10:13:32 GMT

I'm surprised I haven't seen this mentioned before.  I will be reporting
this bug to Sun.  Meanwhile, I want to
   - alert people to the problem
   - ask how people work around it.

Answers to the latter by email please, and I'll summarise.

[Our environment:  network of 27 Sun4s, Sparc 2's and Sparc 1's; NIS master
is a Sun 4/470.  All running SunOS 4.1.1 except one machine (a Sparc 2)
running 4.1.2.]

We are running both NIS and Sun's password shadowing (without group shadowing
or C2 auditing).  On the NIS master, the ASCII source files for the passwd
and passwd.adjunct files are kept in /etc/ypsrc/passwd and
/etc/ypsrc/security/passwd.adjunct.  This seems much more sensible than
mixing them up with the master's local passwords, and is recommended by Sun.

Before I converted to shadowing, root could change any NIS password
by doing a "local" password change on the NIS master:
   passwd -F /etc/ypsrc/passwd username
The -F flag "tricks" passwd into using the NIS source file instead of
/etc/passwd.  After this you do a NIS make and all is perfect.

Now we're running shadowing, the same command assumes the adjunct file is
in /etc/security/passwd.adjunct, and fails with "Not in passwd.adjunct file."
There is no way to tell passwd where the adjunct file is.  You should
be able to say something like
   passwd -F /etc/ypsrc/passwd -A /etc/ypsrc/security/passwd.adjunct username

If I had the source code I would add this feature and give it to Sun,
but Sun don't have the sense to provide their source.

So when a user forgets their password, I have to make a temporary entry
in the local adjunct file (/etc/security/passwd.adjunct), change the password
there using the passwd -F command, then copy the entry across to the NIS
adjunct file.  A colleague has just given me a script which will probably help;
however I'd like to know how other people are coping with this deficiency.

Well, yes, and no.  The helical stripes are at the same density
within the stripe, but the spacing (and orientation) of the
stripes has decreased, so *effectively*, the density has increased.

That is, the tape length is the same for 8200 and 8500, it is the
way in which they are written that changes the amount of data you
get on the tape (filemarks also use much less tape in 8500 mode).
Note that Exabyte claims that the video grade tapes work very
poorly, if at all, in 8500 mode.  Some folks report OK results 
with video grade in 8500 mode, others confirm the Exabyte warning.

It sounds like your 8500 may be writing in 8200 mode for some reason;
if you have an 8200 available, you can easily check that.

I am having a problem with PC-NFS and a Sun 3/60.  The problem is not
critical; it is just plain annoying.

I upgraded three IBM PS/2 Model 70-A21's from PC-NFS 3.0.1 to PC-NFS 4.0
two days ago.  Now, whenever one of them logs into the Sun, the console
of the Sun displays an error message similar (but not exactly like) to the
following:

[date] [time] pcnfsd[100]: rpc.pcnfsd: fail on yp_bind

Then, after a few minutes, the Sun console will say:

last error repeated [x] times (the number changes)


There is NO Yellow Pages/NIS set up on these machines, and I have checked
the setup of the ``rogue'' machine to make sure that PC-NFS does not THINK
that there is any Yellow Pages/NIS service to which to bind.  I basically
am BEWILDERED by this error... _ANY_ help would be appreciated.

As I said, this is NOT critical; just annoying.  I HATE it when things don't
work like they should....

Hi netters,

I'm wondering about connecting a modem to my Sun SPARCstation 1+ (SunOS 4.1.1)
via its serial port.

In particular, I would get the following situation:

1) At home, call the Sun from my PC via kermit and my modem.
2) The modem connected to the Sun replies (it has the auto-answer facility)
3) The Sun offers the login prompt
4) I login into my Sun account
5) I start a program (or a shell-script) such that:
 a) I can hang up at home
 b) In a few seconds, the Sun dials my home phone number
 c) My PC replies to the incoming call and gets a login prompt by the Sun.

Is this procedure possible?
I think so, but I cannot figure out which setup to perform on my Sun and which
software (Public Domain...) I must use.

Any solution is welcome, even partial.
Please reply by e-mail, and I will post a summary.

Thanks in advance.

All went well, EXCEPT:
On bootup, when rpc.lockd is launched, generates the error message
	'cannot connect with status monitor'
about every 5 seconds. Makes it hard to do much until lockd is killed.
rpc.statd IS running, so is there something I have overlooked?

This is not usually set up as an NFS client or server, /etc/xtab,
/etc/sm, are empty, so what connection is this machine trying to make??
The fstab has no remote mounts, and since the machine is NOT 
(currently) attached to the net, where are the lock requests 
coming from??

Thanks for answers and suggestions..I shall sum the results.

Have you ever heard about SunOs (4.1.1) getting in trouble when managing
a swap area larger than (say) 100 Mbytes?

We have the following scenario:
a sparcstation-2 with a ~600 MBytes Hard disk and  a swap area
of 120 Mbytes.

Regardless if the swap area is only the sd0b partition or if it is split
between two partitions or even a partition and a swap file SunDiag
finds lots of errors  when running the test on virtual memory.
On the contrary SunDiag doesn't report any error if we configure
the disk with the standard 32Mb swap partition.

Our Sun assistance tested the disk for a long time and it is OK.
They also said that virtual memory test doesn't fail if the secondary
swap partition  (additional partition) is in a different disk.
What does it mean?
Any suggestion?

I'm using the same Pioneer DRM-600 you are.  A company called Tracer
Technologies makes drivers for Sun and HP.  Their number is
(800) 872-2370.  The great thing is that it will boot off of disc 1,
so you can load solaris, then load the drivers and you effictively have

I've been using Sony P6-120MP tapes in my 8500 for a couple of months
now with no problems.
I suspect Exabyte are trying to push us all into buying much more
expensive data grade tapes.

See network and Communications administration:
page 460:
The automounter consults the master map only at startuptime.
So I guess you gotta kill it or reboot.

About killing the automounter: DON'T use kil -9. the mounts will hang.
Use kill -15, the automounter will unmount first except for busy mounts.

The video grade, P6-120MP tapes are only 104 or 106 meters long.
The Data grade tapes (really P5-90's) are 112 M long, so one can get
5GB on them instead of 4.3-4.5G.  Most if not all the difference between
4.5G and 5.0G is from the tape length, not the error rewrite rates.
On an old (== prototype) 8500, we are seeing rewrite rates of 0.03% to
0.08% which is essentially nothing (on video grade SONY P6-120MPs).
Does anybody know of cheap sources for Sony P5-90's (approx $4.50 each)
in the US?  I have heard of the existance of a P6-150MP? Anybody?

Good luck:-). This is indeed one of the major pains with TFS; I "solved"
it by having root's crontab do periodic 'find's in the TFS tree, thereby
creating any missing directories and their .tfs_info files. This was in
a case where the "underlying" directory structure would change from time
to time, don't know if you have that problem (and if you ever *replace*
directories there, TFS will be very confused) - nor if you really want
all those directories under /usr/openwin/include...

Anyway, I hear TFS is going away as of Solaris 2.x - too bad, I think,
it is quite "interesting"...

Hi

I was playing around with the logging options of
Sun's ftpd daemon (SunOs 4.1.2) and discovered that
the log files contained the passwords that were typed
in by the ftp users. 
This seems to me to be a big security hole even though
the log files can be set to be readable by root only.
Is this a bug in Sun's ftp daemon or are the log
files supposed to contain the passwords?
By the way I haven't checked to see if the telnet
logfiles do this as well.
