We have a system
to which we want to add a second 100Base-T card. Is a license
required for the second card, or does one license cover both?
Chris Goodey replies:
software license is required.
Where do I find a
list of the HP 3000 models that support this 100Base-T network
Chris Gauthier replies:
I can tell
you what models support the 100Base-T interface: All 9x7, 9x9 and 99x
models; all 9x8 models (except that old 948 and 958, because they are
CIO machines). The new A and N-Class systems come with 100Base-T
I am trying to
create a UDC that will prevent a user from having more than one open
session. I am keeping track of who logs on by creating a file each
time the user logs on. If the file exists, it is assumed that the
user is logged on. When the user logs off, I want to delete the file.
To do that, I redefined the BYE command in the UDC. If the user is
already logged in, I want to log the second session off without
deleting the file. When I issue the bye command it is calling the UDC
BYE and not the system command BYE. The UDC file looks like:
John Burke replies:
order of the two UDCs LOGCNT and BYE in your UDC file. This should
accomplish what you want since the UDC commands are processed
sequentially; i.e. when you execute the LOGCNT UDC, the command
interpreter will only look forward of the current position in the UDC
Can an HP 3000 NIC
be configured to have multiple IP addresses?
Mark Bixby replies:
cannot be done today on an e3000.
Doug Becker adds:
There must be
a LANIC for each IP address on the HP e3000. Additionally, if you
have more that one LANIC, they must be attached to different
During a move, our
system fell off the back of the moving truck, damaging it beyond
repair. Were obtaining a replacement, but it is not the exact
same model, though in the same class (9x7). I have an SLT and full
backup. How should I proceed?
Gary Paveza replies:
When we do this for our disaster recovery, we just
install from SLT and reconfigure the I/O. That way, all the software
(subsys/patches/etc) is on the new system. Then its simply a
matter of restoring your data.
Paul Courry adds:
Call your third-party software vendors,
given them the new HPCPUNAME and HPSUSAN number and get them to
generate new unlock codes.
I want to run a batch job that executes a
Posix program. Actually, I want to update my aliases file in my
SENDMAIL account. I got the other commands figured out but not the
newaliases command. Part of my job is as follows:
/SENDMAIL/PUB/bin/newaliases 149: :
/SENDMAIL/PUB/bin/newaliases 151: :
Mark Bixby replies:
tells the shell that newaliases
should be interpreted as a script file. But its a symlink to an
NMPRG, so you see all of those weird error lines as the shell tries
to parse a binary NMPRG as if it were a script.
You want to be doing it this way
:xeq sh.hpbin.sys -c
I am trying to get Apache running.
I ended up using telnet from my Linux box to the HP 3000 and then
trying to use VI (yeck) to edit files. It looks like VI is sending HP
terminal control stuff to my telnet client, which just gets a little
boggled. Is there a better way to proceed?
Michael Anderson replies:
If youre not using an HP
Terminal Emulator than you probably need to set your termtype to
VT100, for example,
John Burke adds:
If you have a Windows PC,
then I always say that before even thinking about setting up Apache,
people should set up Samba. This way you can use your favorite PC
editor to set up your Apache Web server. Setting up basic Samba
access requires editing only one bytestream file. You could then FTP
it to any system, edit it there and FTP it back to your 3000.
On an HP e3000, what is
the relationship between the hardware and software clocks? Is the
software clock a stored offset to the hardware clock? Or are the
hardware clock and software clock reset at reboot, with the hardware
clock running off a clock/calendar chip and the software clock being
calculated based off CPU ticks, or is it something else?
John Clogg replies:
The hardware clock is supposed
to be set to UCT (AKA GMT), and the software time is
derived using a time zone offset that is manipulated by the SETCLOCK
command. It is not unusual to see systems where this relationship
isnt understood, where the hardware clock has never been set
correctly, so the offset is hundreds of hours! The SHOWCLOCK command
will show you the current status of the hardware and software clocks.
In general, the SETCLOCK command adjusts the offset, and the date and
time setup during a system start adjusts the hardware clock.
Stan Sieler adds:
The free FIXCLOCK command
file at www.allegro.com/software/hp3000/allegro.html
can help you fix the hardware clock date/time.
How do I create a basic
Samba share for a user to access his account?
Lars Appel replies:
Something in the line
comment = Access to
path = /ACCOUNT
guest ok = no
write ok = yes
only user = yes
I want to restore
the directory structure of an existing account but to a new account
name. I tried

the operation could not be completed because a nonexistent account

I usually just

stream files to change the account name to the new account and then

lucky that it failed. Dont forget that the ;DIRECTORY option

How do I reset the

I was scanning a
$stdlist for reply messages and came across the following message:

What does the
R option mean when you reply to a message?
R = Repeat. It
prints one more line for you to check the alignment.
How do you

Horner and Neil Harvey reply:
KSAMUTIL, then KEYINFO fileref ;
like to erase all data from two disk drives (LDEVs 3 and 4) I have in
a test volume set and add one to the MPEXL_SYSTEM_VOLUME_SET and the
other to another user volume set. How would I go about this? Can it
be done without disrupting the system?
Optionally (personally, I think it is a good idea),
remove any groups and accounts on test_volume_set, then
mpexl_system_volume_set:member3 3 100 100
appl_volume_set:member7 4 100 0
Thats all there is
to it. And it absolutely can be done without disrupting the

you want to try to do with new disk drives put them in a test

/etc/profile I get a message resource busy, try again
later. I also get this message in error_log sometimes when the
APACHE browser tries to fire up a CGI program (c-language, in MPE
space) and sometimes when I get the shell up and it does get through
the /etc/profile file I can still get the resource
busy... message. What resource can this be?
Mark Bixby replies:
likely cause is insufficient contiguous free disk space which results
in fork() failures. The fix is to defragment your free disk space,
either by using :VOLUTIL CONTIGVOL, or a third-party product like the
ones from Bradmark or Lund.
Is there a
Web site that indicates what the bare minimums are for running on
where it says:
The 6.5 release
will use slightly more memory on a system. HP believes this should
not be noticeable on systems with at least 128 Mb of main memory. If
your system has less than 128 Mb, you may want to consider adding
memory before you update to the 6.5 release. This may not be
necessary for development or test systems with just a few users. HP
recommends that production systems should be configured with at least
128 Mb of main memory for optimal performance on the 6.5 release.
For the first
time ever we have PCs using NS/VT connect. We are seeing some error
messages that I havent seen before from NS/3000.
NS/3000 INTERNAL ERROR IN VT; Job: 0; PIN: 2579 Info: 0

and John Clogg reply:
nscontrol status=summary and look at the number of VTSERVERS versus
number of active. This may be you problem. To change the maximum
number to something higher, use
