      [ multi-person discussion regarding infinite forking program ]
      [ and possible stopping with MAXUPRC in kernel config ]

   Well, a typical sun runs about 15 processes before any user logs in. thus

	   #define MAXUPRC (NPROC - 5)

   will not do you any good: consider a user who -- perhaps inadvertently --
   creates MAXUPRC zombies: the sysadmin cannot log in anymore and kill
   the parent process.

Aha!  Wrong!  The sysadmin *can* still login.  As getty exec's login
exec's the shell, you can login.  The problem comes when you go to do
a ps.  What the sysadmin could do is 'exec su -f <person at fault>',
then do 'kill -STOP -1'  (This assumes kill is a shell builtin as in
csh.  In bourne shell, do 'exec kill -STOP -1').  This will stop all
of the user's processes (except the shell), and a 'kill -TERM -1' (The
-TERM lets the -1 be passed to the kill(2) call) will kill them.
Unless the person had them catch SIGTERM, in which case it is quite
clear that this wasn't an accident... (okay, maybe not, but still,
they better have a *gooood* explanation!)

Something very similar to this happened to me when a cron job I was
running filled a machine process table with rsh's that where jammed as
the next was paritally down.  There I did a 'exec ps' and could get
away with it because the cron only ran every 4 hours (I vaguely
remember).

Subject: Cry for Help! CU/FTP Script Problems
Summary: Trying to use a script to make dialup slip ftp easier
Organization: E-Mu Systems
Date: Wed, 27 Jan 1993 16:20:14 GMT

 
We're using a dialup ftp service with slip to get anonymous ftp access.  
However, the process for doing this is onerously complex, and I'd like
to make things simple for my users.  Here's what I have to do:

1.	cu pslip

      	I use cu to connect to the remote host.  There's some dialing
	and whatnot, then we're connected.  Usually I have to hit a 
	CR to get a login prompt.

2.	Give login id and passwd.  Prompt appears.

3.	some_prompt> slip

	I type "slip" at some_prompt, and get something back like:

	Starting SLIP.  Your IP aaddress is xxx.xxx.xxx.xxx....

4.	Use a ~! to start a shell back at my local system.

5.	Now, back at the local system, I execute the command:

	slip-attach [tty] [baud rate] [IP addr from above] [IP again] [netmask]

6.	Now I need to add to the routing table:

	route add [IP addr] 1

7.	Proceed to do ftp commands....

8.	When I'm done ftp'ing wunnerful source code from the ends of the earth,
	I type exit, to return to the cu session.  Now, I type ~. to end that.

9.	Back at the local system, I need to kill slip-attach, and delete
	the route from myu routing table.  

What I tried to do was a script that did the cu, took the login and passwd
from a file, then redirected the output to a file where I could grep
the IP address from.  But cu was inconsistent in getting the login and
password accepted; that is, it appeared to depend on the server's response
time.

So, is anyone with PSI's Host-Dial service doing this ftp in a - cringe -
"user friendly" manner?  Can anyone help me with this problem?  I'd really,
really appreciate it.  Thanks -- send email, perhaps in addition to posting
to this group, since one cannot guarantee reception or reading of every
article in all these groups.

Eek!  This post made me look fondly at the UPS that is powering my

Obviously, this doesn't help sort out your disk problem, but might

Hi,

  I have a special situation where I want to have the Sun Sparc-2 running 
SunOS 4.1.1 to be a telnet server front end to a mainframe telnet server.
But I only want to login once, so I have to find out how to disable login
banner & all from the front end telnet server, so that the telnet connection
goes all the way thru, then the mainframe generate a login banner instead.

  Is it possible:

  (1) In SunOS 4.1.1 ? Without getting the telnetD code & hack it, by just
  fixing the inetd.conf or ttytab or whatever?

  (2) In 386BSD (BSD 4.4 or 4.3?), by changing inetd.conf telnetd to include
  argument "-a none" ?

  Thanks for any information.

I want to configure a ELC with a SCSI HD so that it can be booted both over

Standalone not knowing about the Rest of our Clusters and Domains. When it
boots from the Net, I want it to be a Member of our Cluster (= NIS Domain,
sorry, I don't like to have to say "NIS" or "Internet" everytime I say
"Domain"), but I would like it fine if it would reuse the independent
Stuff on the Disk - ie. /usr and the Swap Partitions.

However, when I try to specify a local Partition in bootparams, it won't
boot; And if I have fstab try to put up what I want, /usr and (at least)
the first Swap Partition can't be unmounted anymore.

I've got 4.1.2 installed. Is this inevitable? Or is there a Way to have
the /usr FS "swapped", at least?

I use a programm called Pcomm.  It is similar to the popular PC program
ProComm.  It includes several popular file transfer protocols.  I forget
where I got it but an Archie server can tell you where to look.  Xmodem
comes with Pcomm but zmodem is assumed to be a separate program that
Pcomm invokes when it performs a file transfer.  You will need to get
zmodem code and compile it.  I have copies of both pcomm and zmodem for
the Sun so if you can't locate it I could make mine available.  If you
are dead set on using kermit I think zmodem can be used with it, though
I've never tried it.

Hope this helps,

Summary: Can I apply other patches to a DBE system?
Keywords: SunDBE lockd patch panic
X-Newsreader: NN version 6.4.19 #1

I have attempted to apply the lockd Jumbo patch (100075) to a Sparc 2 running
4.1.2 several times in the past few weeks. I have tried both version 8 and
version 9 of this patch.

Every time, within a few minutes of rebooting after applying the patch, I get:

	vmunix: kmem_free: free block overlap fd87d878+4096 over fd87e638
	vmunix: panic: kmem_free: free block overlap

...and the system dumps and reboots.

This system has the SunDBE (database accelerator) software installed, but no
other patches. I know that DBE changes the kernel VM implementation. Is the
lockd patch compatible with DBE? Do I have to install the patch into a GENERIC 
kernel and then apply DBE?

My posting this article isn't any reflection on Sun support (who have never 
seen this problem before), but other people may have experiences they wish to 
share. Sun support have suggested reinstalling Sys (in case of any corruption), 
installing the lockd patch, and if all goes well, install DBE afterwards.
These sound like sensible steps which I will try.

Thanks in advance. If there is sufficient response I will summarise and post.

Thanks for all the help with my FDDI connector query!  Now, on to the
next one:

We have a Sun SPARCserver 4/490 (soon to be upgraded to a 690).
Inside it has the SCSI mounting tray where the cd-rom drive is.  On
the left of the mounting tray are 2 cd-rom drives, on the right is an
8mm tape drive.  Thus, the SCSI mounting tray is full.  The
SPARCserver cabinet is also full.  Next to this SPARCserver, connected
to it, is a Sun expansion cabinet, that has 2 IPI disk drives in it.
We'd like to get several more cd-rom drives.  It seems to me that I
should be able to order the SCSI mounting tray, and some SCSI cable,
so that I can put more cd-roms in the expansion cabinet.  But I can't
find the part number for it, or the cable, in Sun's price lists.

Does anybody know how to accomplish what I'm trying to do?

The problem is that this request isn't being sent to the remote machine.
Your machine has the file cached in memory.  Therefore, it's making the
access decision locally.

I think Sun has a patch for this.  Since it's security-related, it may even
be in the UUNET patch archive.

This doesn't explain why you were having the opposite problem, though.  In
that case, the file shouldn't be cached, so when you try to access it as
yourself your system should try the NFS request again.
