I have an HP 3000 that is
set up for full access to the Internet for testing purposes. The
telnet connection works fine, but I also see that VT-MGR also works.
I know that inetdsec is used for restricting access for ip, http,
ftp, etc. Is there something in NMMGR that you setup to restrict
VT-MGR access, or do you use inetdsec for that also?
Chris Bartram replies:
Just an option logon UDC

We have a site that is
still on MPE/iX 5.5 PowerPatch 7. Will it be possible to update
directly from this version of MPE/iX to version 6.5?
HPs Jon Cohen replies:
You can update directly
from 5.5 to 6.5 without stopping on any version of Release 6.0.
I know there is a way to
find CPU connect and diskspace usage, but I forget. What is it?

If you have volume sets you
have to do the following:
- DSTAT ALL to get the volume names
- REPORT @.@;ONVS=volume_set_name
The report command using a
REPORT X.@ will only give you totals by account total. REPORT @.@
will give you totals by group within the accounts. REPORT @.account
will give you totals of groups within an account.
I was doing a REPORT
@.account and noticed that the filespace used reported for the
account was greater than the sum of the filespace used for each
group. How can this be?
Dave Knispel replies:
Sounds like you have
Posix files attached to the account. Log onto the account and type
This will show any HFS files
or directories attached to the account.
I know that third party
back-up software packages have an *EXCLUDE* command that excludes
certain files/groups/accounts from the STORE process. I cannot seem
to find an equivalent command in STORE. I am using the regular
TurboStore that comes with the FOS. Is there an EXCLUDE command in
Joe Taylor replies:
You can use the minus
sign to exclude files/groups/accounts. For example
STORE @.@.ACCOUNT -
@.GROUP.ACCOUNT - FILE1.GROUP.ACCOUNT ...
In the command line version
above, the number of excluded filesets is limited by the CIs
limit on command line length. If you use an indirect file, the number
of filesets you can exclude is unlimited.
How do you check if a
previous command ended correctly in a shell script?
Barry Lake replies:
Check the built-in shell
variable $?. That should give you the exit value of the
last executed command.

Another option might be:
Whats the trick to
getting an NT client to work with Samba on an HP 3000? I recall
something about clear-text passwords? Where is this set?
Michael Gueterman replies:
Clear-text passwords can
be re-enabled under NT by applying a registry patch available in the
download area of the Sambaix.com Web site (www.sambaix.com; there is
a patch available for WIN95/98 there as well). Simply download that
file, then double click on it to have it installed.
What is the command for
changing the system date?
David Knispel and Bill
Proudfoot replied (in about a nanosecond):

want to set up some security. How do I set up a folder that is only
accessible by using the logon/password screen at the PC? Where do the

Im trying to
restore files from a tape created on a DDS-II drive on a system with
a DDS-I drive. I get the following error: RECSIZE OF RECORD HOLDING
STORE/RESTORE LABEL WAS NOT 40 WORDS (S/R 6188). What could be
Denys Beauchemin and
Christian Lheureux reply:
- The tape was not
written with Store.
- You have a compressed tape
being read by a drive that does not support compression.
- You have a drive that
writes tapes no one else can read or a drive that can only read the
tapes it wrote and no one elses.
I am getting an error
message when I boot up my HP 3000/967: WARN E040 and
WARN EF40. Whats causing this?
Doug Werth replies:
This means the internal
battery is charging. Series 9x7 machines still had a memory battery
backup that allowed the HP 3000 to recover from a power failure. It
is one of the things that used to differentiate the 3000 from all
other systems. Now you have to have a UPS instead.
The console status
messages will go away once the battery completes charging.
One problem I keep running
into is the incompleteness of SHOWPROC. The shells ps command
shows more processes than SHOWPROC but the PID appears to have no
relationship to MPE PIN. How can I see the entire process tree for a
system from the MPE prompt?
Jeff Vance replies:
If you are on 6.0, then
give you the entire process tree for #Snnn.
By the way, a PID is the
following structure (in Pascal):
pin : bit16;
cnt : bit16;
so there is a relationship
between PINs and PIDs.
When I purge all the files
from all the groups in a particular account, do I recover that disk
space? Or is it allocated and un-usable until I get rid of the groups
Bill Lancaster replies:
That space is recovered,
though probably fragmenting your disk, as soon as you issue the PURGE
Ive heard about a
command called KILLSESS to get rid of VT sessions, but cannot find it
documented. How do I use it?
Jeff Vance and Barry Lake reply:
You have to have NM
capability to do this.
How can I print from a
3000 to a non-JetDirect printer using the Native Mode spooler?
John Burke replies:
The printer MUST support
basic PCL. I actually have several of the old 2934 character printers
happily connected to JetDirect boxes and spooled using the network
print spooler. Works fine. Ive also been able to use non HP,
but PCL-compatible, laser printers.
As for the network
interface card/box, ideally it should be either a JetDirect or 100
percent-compatible. However, by using the undocumented option
snmp_enabled=false in npconfig.pub.sys, you should be
able to use non-JetDirect cards/boxes. Ive successfully used
Intel NetExport boxes for example.
On an Intel Box with 3
ports (2 parallel and 1 serial,) what NPCONFIG parameter would tell
the spooler which port the printer is on?
Again, John Burke replies:
Parallel 1: tcp_port_number=3001
Parallel 2: tcp_port_number=3002
The three-port JetDirect
boxes only get one IP address, so how can I set up network printing
to print to any one of the printers attached to one? Do I use the
John Burke and Richard
Yes, the port numbers are
9100, 9101, 9102.
If we have an e3000, can
we restore our full system with only a CSLT and TAR format backup
Lars Appel replies:
No. Keep in mind that
TAR, unlike STORE, does not handle all the different file types
available on the MPE/iX file system. I have never tried, but I would
doubt that PRIV files like TurboIMAGE datasets can be tar-ed
successfully (to give one example here).
Tar is nice for data exchange
with other open systems, however STORE (or other
MPE-specific backup tools) would be the preferred backup solution.
What would be the ASCII
representation of the Block Mode <numeric pad>
Richard Trapp replies:
The ENTER key
(from the numeric keypad) really isnt a character that is sent,
its actually a function that is executed. Unless its been
set to ENTER=RETURN, it actually initiates a block
transfer. You can initiate this programmatically by sending an
It transmits a
block of data (either the current line, or page depending
on settings). Its most commonly utilized by VPLUS in Block
Mode, but can be used in LINE MODIFY or MODIFY
ALL mode for local terminal edits.
How can I turn software
compression off on a HP e3000 DDS drive?
Jim Killam and John Burke reply:
compression=disable where N is the ldev of the tape drive.
Is there a simple way to
concatenate two or more files into one? For instance, copy file_1 +
file_2 + file_3 into file_4? I know I can do this on a DOS box; how
about a HP 3000?
Tom Brandt replies:
1. Execute a file
equation specifying APPEND access for file 4:
2. FCOPY the other files to file 4:
Make sure FILE4 is large
enough to hold everything from files 1, 2 and 3.
Mark Bixby adds:
Using the POSIX shell,
cat file_1 file_2 file_3 >file_4
Is there a simple (i.e.,
not doing a showjob and parsing output) way to determine if a
scheduled job exists? We have a :JOBCHECK command file which checks
to insure that all of our daemon and other type background jobs are
running by issuing a :tell jobname,user.acct Are you there? and then
checking the CIERROR for the unique message saying that the only
qualifying target is a job, so the job does exist. If you get the
error saying no such job exists, you can take action to restart it.
However, I have found no equivalent for scheduled jobs. Am I
overlooking something obvious?
John Burke replies:
sched;job=jobname,user.acct sort of does it. Unfortunately, it does
not set a cierror value if there is no job.
In these cases, what I do is
redirect the output of the showjob into a file and then just look at
the eof. In the case of no matching job, the eof is 3. If one or more
jobs matches, the eof is greater than 3. This should be very quick
and does not require any parsing of the re-directed output.
Adam Dorritie suggests:
How about using LISTSPF
on your input spoolfiles with a combination of the OWNER and JOBNAME
selection parameters with the output directed to $NULL. If the job
you specify isnt out there, youll get a CIWARN 4809, so
you can just set
CIERROR = 0, LISTSPF
I@;SELEQ=..., and check CIERROR = 0 or 4809 to tell you if the
scheduled job exists.
Finally, Jeff Vance suggests:
If you are on 6.0 PP1,
and you know the job [jname,]user.acct logon ID, you can
JOBCNT(jname,user.acct) > 0 then ...
