When upgrading an
old system from 5.0 to 6.5 are there any mandatory versions in
between that one must upgrade to before getting to 6.5?
Tom Hula replies:
the System Software Maintenance Manual, you would have to upgrade
from 5.0 to 5.5 or 6.0 first. Then you can upgrade to 6.5. There is
no way to get directly to 6.5 from 5.0.
We set up
three Intel Netport print servers to three different printers using
the snmp_enabled=false directive in NPCONFIG.PUB.SYS. The
HP LaserJet works great. The other two printers are Okidata ML series
printers. One prints junk on top of each form and the other one just
prints junk. If we use an External JetDirect card with the Okidatas,
will this work?
John Burke replies:
MPE/iX network printer spooler is hard-coded to send out several PCL
commands (escape sequences) in the normal sequence of
printing a spool file. There is no way to suppress this.
Virtually all laser printers, whether made by HP or not, understand
PCL. This is because of HPs dominant position in the laser
printer market. On the other hand, virtually no non-HP character mode
impact printer understands PCL. In particular, none of the Okidata ML
printers can process PCL; hence the junk. Sometimes the junk can be
pretty spectacular if the printer interprets some part of the PCL
escape sequence as a command in its own language imagine the
The only way you can
successfully print to your Okidata printers over the network from the
HP e3000 is with one of several third-party products. HP has
steadfastly refused to enhance its network print spooler, deferring
to the third-party vendors.
problems using Reflection 7.0 to upload files to an e3000 (6.5pp2)
across the Internet. I have tried both telnet and VT without success.
The transfer just seems to hang.
Joe Silagi replies:
is likely a firewall interfering with Fast File Transfer.
Reflections Fast File Transfer (FFT) uses a separate TCP
connection. On the pc the port FFT uses is 30767. On the host side
the port number varies but is in the range 30000-40000. Firewalls
will need to be configured to allow access to these ports. If the FFT
negotiation fails (default behavior) Reflection will use the session
port for the file transfer. In the File Transfer Setup you can
configure Reflection to negotiate (default), always or never use FFT.
You may need to disable FFT.
I need to verify
within a STREAM that a file does not exist. If it does exist then
abort, else finish the job. I am trying to make sure a file is not

Today I got a new
PC with Windows 2000. My password-protected Samba Shares do not work
any longer. The other, unprotected, shares work like a charm. Any
hint to solve this problem?
Make sure you
have applied the Win NT 4.0 registry patch (which works just fine on
Windows 2000). Also, if you are using a user.map file, you may need
to make some alterations to it. Ive included that information,
which was provided by Greg Stigers, in with some other Win2000 notes
in a document entitled Windows 2000 and Samba/iX Issues
available at the Document Library section of the sambaix.com Web site.
HPs scrollable pick list enhancement to VPlus
has this enhancement been done or not?
Mark Undrill, Nick
Demos, Lars Appel and Michael Berkowitz reply:
It has not
been done. After starting it, HP decided not to do it and rely on
What is the upper
limit of LDEV numbers?
Stan Sieler and
Christian Lheureux reply:
the version of MPE/iX:
1.1 .. 3.1 MAX_LDEV = 999;
4.0 .. 4.5 MAX_LDEV = 2330;
5.0 .. 7.0 MAX_LDEV = 4679
Stan Sieler adds:
wouldnt be surprised to find that some code doesnt like
disk drive LDEVs larger than 999.
Is there a way to
empty Apache log files?
Mark Bixby replies:
Apache has a
rotatelogs utility that will automatically create a new logfile after
some fixed time interval. You can get it at httpd.apache.org/docs/programs/rotatelogs.html
MPE :PURGE should
complain about log files being in use. But if you do a Posix rm, the
log file will be purged, but what happens next is probably not what
you expect. The log file doesnt really get purged until the
last accessor has closed it, and so the network server will continue
to write entries into the now hidden log file, consuming
additional disk space. Once you terminate the network server that is
writing to the log file, the file will finally be removed from disk.
So its cleaner to clean up your log files when the relevant
network server isnt running.
Many Posix network servers
however will allow you to do something like this while the server is
still running (Apache works this way):
logfile.old (rename the active logfile)
kill -HUP nnn (send
the HUP signal to pid nnn to cause a server restart)
the now closed logfile.old
rm logfile.old (purge
