I just built a new version of rn (version 4.4) and it does not have an option
that an old version had (version 4.3). The 4.3 version I had an option in
rn for adding new newsgroups in one shot via a "YN" option.
I checked several sites for a version with this option without success.
Does anyone have this version of rn or was this a local hack?

Unix World subscription...

I have two numbers:

609-426-7070  ( Outside USA )

That should get you through to the right desk-jockey in order for

Subject: yp (nis) map changes - how do they happen

Organization: InterLinx Support Services Inc.
Date: Thu, 27 Aug 92 18:03:40 GMT

Here's an interesting question.

Scenario:

I have numerous machines from numerous vendors running different versions of
UNIX.  All support YP (NIS).  I have one master server for NIS and all of the
other machines are clients.  I can therefore have it set up so that only one
machine keeps the passwd file and all of the other machines use YP to get the
passwd entries for the users (all users can log onto all machines).  A user
logs onto one of the machines and wants to change his/her passwd.

1. Is this allowed on any machine, or just the master where the "real" passwd
file is?

2. If so, then the passwd program must be YP intelligent.  Is this a possiblity?

3. If 1 and 2 are true then the passwd utility on each machine must be able to 
update the master and the maps?  True??

Or maybe I'm just living in a dream world??

I have found that top (the program by William LeFebvre) is an extremely

Unfortunately, I lack such a utility on our SVR4-based platform.  Has someone
done a port?  I started looking at what's involved and it's way beyond me.

Or perhaps is there a similar utility for SVR4?

For a temporary solution, change the user's current working directory to 
one where he (or she) doesn't have write permission.  Naturally, the best
solution is to fix the program so it doesn't dump core in the first place.

Nope. What he did is to put a meaningless line in his password file and to
instruct his system not to use the NIS passwd map (or reather not instructing 
it to use it).

I suggest people should at least read SunOS's System & Network admin book, 
before they venture to touch /etc files.

 Our root file system is nearly full. Thus it overflows periodically since
 vi and mail have /tmp hardcoded in them for creating temporary files.

 What problems might arise if we did the following?

   mv tmp tmp.save
   ln -s /usr/tmp /tmp

 One problem I foresee is that /usr is not mounted in single user mode.

I want to connect an Hayes-compatibel MNP5-Modem at our Sparc2. It's only for

like kermit, telix, uniterm (normal vt100 emulation) to log in from outside.

What do I have to do?

The type of the modem is Discovery 2400 BPS from DATATRONICS (I think, this is
not important).

I experimented with a normal getty; it went well, but after half an hour the
modem hangs up.

One user on an SGI system I use elsewhere is given job priority 24 for all

1. Can a priority default be set permanently for one user, which is different

2. How is 1. done?

3. If 1. is possible how can the default be restored?

The only really obvious difference between this user and all othes is that

The ones I have observed on my 8.05 are all related to file locks.
If the process is trying to lock a file on an NFS mounted partition,
and for some reason, the lockd on the NFS server has gone to lunch,
the client process will not exit with anything until the lockd on
the server has reappeared and responded.

Otherwise I haven't seen any other unkillable 8.05 processes.

Subject: Setting up a network firewall
Organization: Roadnet Technologies, Inc.
Date: Wed, 26 Aug 1992 15:26:45 GMT

I'm trying to get information on how to configure a firewall system --
that is, a system through which we could connect our internal development
network to the Internet and maintain a modicum of confidence in its
security.  We have a SCO ODT system which we connect to the Internet via
dial-up SLIP, and we want, for various reasons, to connect this system to
our internal network, but we are concerned about providing some
reasonable security.  The scheme I have in mind is basically that the 
firewall will not be able to forward packets between the two network
interfaces (the SLIP link and an Ethernet hose).  In this scheme, our
users could telnet from internal systems to the firewall, and from there
could perform whatever Internet stuff they wanted.  The firewall should
be able to telnet or ftp to either internal systems or to external
systems, but would refuse any (I *do* mean any) packets bound from the
external systems to internal systems (i.e. it wouldn't function as a
gateway at all).

I would appreciate suggestions on how to set up such a firewall, and if
this is a reasonable idea.  Replies via email to pmj@roadnet.com are
welcome, as are posted replies.  If folks are interested, I'll summarize
and post.

Thanks,

We were having the same problem on a 9000/827 system running HP-UX 
8.02.  It turned out to be that we had the system setup as a "trusted"
system.  When I talked to HP support they first placed the blame on the 
Sun system that we are running as a client.  I setup an 9000/807 as a 
client and had the same problem.  At this point HP support told me it 
was because of the "trusted" system configuration and I would have to
do a complete OS reload to get rid of it.  In talking to someone else 
at HP support I was told that it might be possible to back out the
trusted setup.  

If this is your problem contact let me know via email and I will give
you the details.

Under linux.... Hmmm... If adb or something similar is available, you can
hand edit the inode to convert it to a file entry, and then remove it. If
you don't have adb, boot from a DOS floppy with something like Nortons'
or Mace utilities and use the sector editor they have.

I'm puzzled as to how this was created; after you get rid of the bogus
entry, you may want to manually create the directory to avoid this happening
again.

One simple method that should work on all UN*X systems is to create a file
named "core" in the working directory of the offending program, and give
it no permissions:
	echo > core
	chmod 0 core
Then the program will not produce a core, since the file "core" already
exists, but is unwritable (see signal(2)).
