At our department there is a Pathworks server with two Ethernet interfaces.
One of the interfaces is to the Internet, the other interface connects a number
of DEC PCs to the server. This works fine, except that now the PC users wants to
access the outside world. In the /etc/rc.local file, the following lines 
set up the interfaces:

/etc/ifconfig ln0 129.177.41.1  broadcast 129.177.41.255 netmask 255.255.255.0
/etc/ifconfig ln1 129.177.40.52 broadcast 129.177.40.255 netmask 255.255.255.0

All nodes on both sides of the server uses such broadcast and netmasks. 

Somewhat later rc.local routed is started:

[ -f /etc/routed ] && {
        /etc/routed -q & echo 'routed'                          >/dev/console
}

Unfortunately the nodes connected to the ln0 interface can only be reached from
the server, no matter the settings of the interface - if pinged from the 
ln1 side, none of the nodes on the ln0 side can be reached. From the server one
can ping both networks successfully. 

I would appreciate any ideas on how to make this work. We are running Ultrix 4.2

Subject: Using WP50 w/NFS mounted directories
Organization: Powertrain Electronics, Ford Motor Co.
Date: Thu, 3 Sep 1992 18:51:21 GMT

I am having a problem using WordPerfect 5.0 on a DECstation running Ultrix with
the current working directory on an NFS served device.  All of my user's
directories will be served from our primary server to all client workstations
so this problem essentially stops us from using WP.  Also, we use the
automounter extensively.

Whenever WP accesses the NFS served disk (to either read in a file or write one
out) I get an error message similar to:

Error: File in use by root ---/tmp_mnt/ford/ed8200/ed8200/u/cannell/x.wpf

The user (who supposedly has the file in use, in this case root) is sometimes
other users who are logged on the system and who have nothing at all to do
with this file or directory, so it seems to be just gibberish.

I have to believe that there is someone else in this big world who uses the
same combination of software (nfs, automounter, and WP) that has also come
upon this problem.

Any help would be appreciated.

We are also seeing the same problems, again with a fairly heavily loaded
DECstation 5000/200 as the NFS Server. As yet we haven't managed to get
any handle on it, other than that it appears to be load dependent. If you
have a solution, please share it with the net rather than emailing it!

I have been trying to setup a print service over lat.  I can print

first of all, don't passwd and yppasswd lock the password file differently?
I'm worried about this.
And, the source password file lives in /usr/var/yp/src.  I guess I could
Change that... Besides, these machines have a lot of users that are
unfamilar with Unix, and I don't want them to have to log into the server.

 The X server gets at the graphics hardware via the /dev/mouse device;
if this file is owned by root and mode 644 (as it is in the default
distribution), then only root can run X servers. The better solution
is simply to chmod it to 666; it doesn't allow multiple accesses at
once, so you're still safe against people snooping on your screen.

 Perhaps DEC might want to document this somewhere? I think I figured
it out either by reading the server source for X11R3 or by simply
chmod'ing 666 anything that looked graphics related in /dev.

>Can restore read a tape made by rdump?

	You are correct in assuming that the data storage is the same,
only the device read/write routines are different. *dump should be able
to write tapes readable by *restore, as long as nobody has "added value"
unduly between versions. That is to say, I can't state categorically
that a dump tape from a CRAY will be readable on a DECstation, or a
DECstation on a Sun. Dump has a lot of "knowledge" about file systems,
and makes little effort to save it in a portable or machine-independent
format.

>Further, are these interchangable with the new dump/restore that mjr did?  and
>does that support network dumps (rdump)?

	They are interchangeable to the best of my knowledge. Since dump
and restore don't have any kind of conformance test rack, this is based
on actually trying it a few times. ;) That can't prove correctness, but it
may improve comfort. Give it a shot! As always, any code you get from me
that you didn't pay for is unsupported, as is, do not take internally,
in case of accidental ingestion, consult a doctor immediately, etc, etc.

Organization: Penn State, Laboratory for Elementary Particle Science
Date: Wed, 2 Sep 1992 02:13:42 GMT

Lately I've been trying to compile sps, top, ofiles, lsof .... with very little
success on our Ultrix 4.0 system.  I run into problems with the proc struct
defined in sys/proc.h.  The p_flag member is broken up, but that's pretty easy
to fix.  What has me stumped is the p_swaddr member.  After reading up on the
BSD kernel, p_swaddr is said to be the address of the user area in the swap.

The following comments are from sys/proc.h:

 * 12 Jun 80 -- gg
 *      added 4 new fields p_dmap,p_cdmap, p_smap,p_csmap for dynamic swap.
 *      removed p_swaddr from proc structure.

(Judging from the other comments, I suspect the "80" should be "89").  So,
after reading these comments, I assumed that one of the other fields replaced
the functionality of p_swaddr.  But as far as I can see, none of the other
new entries seems to correspond to p_swaddr.  Admittedly, I am not very
knowledgable about Unix internals.  Does anyone know how to get p_swaddr, or
better yet, get the user area of a process while it is in swap?

Yes, it's doable with about 20M of disk space (if you include fonts).  I've
never actually done it on a DECstation but you can definitely copy what's
done to Sun-3s to make them X terminals.  You can ftp the examples from:

	sol.ctr.columbia.edu:/pub/Xkernel/Xkernel.1.5.

Basically, just boot with vmunix, and make /bin/init be a shell script that
does minimal setup with ifconfig and stuff, then exec the X server.

In case you haven't worked it out, if my .rhosts is too long, then rlogin
will get me in, but no groups will be initialized, no utmp entry written, 
and no wtmp entry entered. This occurs if I login from a SunOS4.1.1 machine
or a Ultrix4.2 machine, so it's probably rlogind causing the problem.

I realize that I can make my .rhosts smaller and the problem goes away, but
this does not stop other users on the system from avoiding entry in utmp
by having a big rhosts file.

Has anyone got a fix?

I'm running ULTRIX V4.2 and my shell is csh(1).  When
I try the command I get:

/usr/ucb/: Permission denied.

This suggests that the shell has resolved the lone $ as
a null string, fed that to it's path search algorithm
and got came up with "/usr/ucb/", which it then tries
to execute.  Perhaps in your case "." is the first element
of your search path (not wise) and so it tries to execute
a null string.

In both cases it is probably trying to execute the directory.

What do you *think* it is supposed to do?

I hate to plug a commercial product here, but I'm going to do it anyway...
(I'm not affiliated with these guys at all, other than a kinda happy customer).

Take a look at Zmail, from the guys that gave the world mush (mail user shell).

It has Motif interfaces, curses interfaces, line-mode interfaces, and Openlook
interfaces, runs on everything, supports all kinds of cool features, the
list is endless.

Definitely get it.  Pricing is OK.  With the caveat below...

One BIG gripe.  (Had to be one didn't there... :)

Licensing is seriously hosed for a person that wants to buy mush for
themselves.  It's locked to a machine, I think it's the IP address or 
the ethernet address or something stupid like that.

If you're a single user, wanting to spring for a mail package that you can
run on multiple machines, then zmail is not for you, it sucks rocks.
I wanted to be able to run it on 2 different machines.  Not at the same time,
but even if I did, I'm the only one using it.  I wanted to install it into
my account, but it can't be done.  It has to be in /usr/lib/Zmail or
somesuch.

The moral of the story is, don't buy it if you're a single user wanting a 
nice X based mail package to run.  If you're stocking a 5900 for 200 users
or something, then it's definitely worth looking into.

a process can use the kill system call to send a signal to another 
process or itself.  btw:kill is a misnomer since a signal does not always
terminate a process.  the syntax is as follows:

	int kill (int pid, int sig);

keep in mind that to send a signal both the sending and receiving 
processes must have the same effective user id, or the sending process 
must be the superuser.

alternatively, a simple divide by zero should result in the generation 
of this signal.
