First published 20 June 2005 (Media Kit Release)
Last revised 10 March 2006 (Maintenance Pack 2)
This document contains important notes, known limitations, and workarounds for SCO OpenServer™ Release 6.0.0 and for Release 6.0.0 Maintenance Pack 2 (MP2). You should read these sections before you begin to install either of these products.
NOTE: MP2 and other updates for Release 6.0.0 are available from the OpenServer 6.0.0 Supplements Web Page: http://www.sco.com/support/download.htmlproduct.php?pfid=12&prid=20.
Check back here periodically. New information, including additional limitations and workarounds, is published as it becomes available.

The instructions given in the CD and online MP2 Release Notes for installing the device driver packages supplied with MP2 are incorrect. To install any of the drivers included on the MP2 CD, enter the following commands:
# mount -F cdfs /dev/cd0 /mnt # pkgadd -d /mnt/imagename.image drivername
Where imagename and drivername are any of the following:
| imagename | drivername | Description |
|---|---|---|
| ahci.image | ahci | Updated AHCI Host Bus Adapter (HBA) driver. |
| ide.image | ide | Updated IDE Host Bus Adapter (HBA) driver. |
| nd.image | nd | Updated Network Driver Package. |
The manual page for ftp(TC) on the installed system does not match the ftp command delivered with MP2. The correct page is available at http://osr600doc.sco.com/en/man/html.TC/ftp.TC.html.
Installation of the maintenance pack may fail if your PATH environment variable contains "/u95/bin" and your system has MP1 installed. When installing on top of MP1, the PATH variable should either omit "/u95/bin" or include it after one or both of "/bin" and "/usr/bin".
The PostgreSQL Upgrade Notes provided in the MP2 Release Notes refer to version 8.1.2 of PostgreSQL; they should refer to version 8.1.3, which is included in MP2. The upgrade instructions apply equally to version 8.1.3.
/etc/pgsql startstarts the database, and
/etc/pgsql enableensures that the database is started automatically on the next reboot of the server. Use
/etc/pgsql -hto list all the options.
The original bug descriptions can be found by searching the MP2 Release Notes for the reference numbers given below.
For information on using SCO OpenServer Release 5 hard disks on SCO OpenServer Release 6.0.0 systems, see the SCO OpenServer Migration and Upgrade Guide.
At this time, USB printer support is not functioning correctly.
We are working on this problem and will post the solution here when it
is available.

Depending on the network adapter that you are using, you may experience sluggish system performance if you have networking configured on your system but the network cable is disconnected.
This happens because of a conflict between the system and certain network adapters when the system polls the NIC to see if the network cable is attached. This conflict can cause high levels of CPU activity, thereby impacting overall system performance.
To address this problem, modify the DLPI daemon
startup script, /etc/nd, so that the
dlpid(ADM) command uses the -s option.
This flag controls the frequency with which dlpid
polls the NIC. The default is every 10 seconds.
To increase this interval, specify the desired number of seconds.
For example, to change the system to poll the NIC
every 60 seconds, specify:
dlpid -s 60
Adjust this setting as needed to improve performance
on your system.

If you are using an Intel® PRO/100+ (eeE8) network adapter in half duplex mode and you remove it from the network, your system may fail to reconnect to the network after you plug the network cable back into the NIC. This problem occurs if you are using a 10Mbps or 100Mbps network hub that has problems auto-negotiating with the eeE8 network driver.
If you encounter this problem,
run the SCOadmin Network Configuration Manager
and modify the Intel PRO/100+ configuration to use the
``HalfDuplex_10Mps'' or
``HalfDuplex_100Mbps'' setting instead of the
``Auto_Auto'' setting. Then reboot your system.

If you are using the Intel Centrino PRO/Wireless 2200BG NIC with Wired Equivalent Privacy (WEP) support enabled, you may experience periodic networking hangs when transferring large files. If the ipw driver senses a hang, it attempts to restart the NIC, which usually corrects the problem.
This problem does not occur if WEP is disabled. To disable WEP, run the SCOadmin Network Configuration Manager and reconfigure your network adapter. Note, however, that disabling WEP relaxes the security of your wireless network.
Problems have been observed when installing from loaded software
using custom(ADM).
It is recommended that you do not use these options until a fix is
available.
Instead, use media images from CD, hard disk, or from another machine
on your network to install software onto your system.
Should you install software using loaded images and experience
problems, reinstall the software from media images.

At this time, SCO OpenServer Release 6.0.0 does not support beginning a fresh install over the network. A fresh install must begin using CD media. After the operating system, is installed and running, you can still install individual products over the network from another Release 6.0.0 machine using custom(ADM).
The netisl(ADM) manual page delivered with Release 6.0.0 is
not correct and has not yet been updated to reflect how to configure
an SCO OpenServer Release 6.0.0 network install server.
When network installation is available, a revised manual page
will be provided here.

To avoid the possibility of license conflicts, it is recommended that you set the correct date and time in your computer's BIOS before installing SCO OpenServer Release 6.0.0.
When you enter your SCO OpenServer license during the installation, SCO OpenServer records the license start date and time based on the current BIOS Real Time Clock (RTC) configuration. If the correct time for your area is actually earlier than the RTC configuration, and you then use the Time Zone selection screen (later in the installation) to correct the system clock, the system will wind up unlicensed.
Note that you cannot remove and reinstall your SCO OpenServer license
to correct this type of license conflict. You must wait
until the RTC advances to the
date and time originally recorded by the installation.
At this point, the system will be licensed and functional.

If your system contains multiple disks, you may experience a problem where a USB floppy drive is unable to read an HBA floppy diskette during installation. You might also encounter this problem on a system with a single hard drive if you have multiple USB floppy drives installed.
The simplest way to avoid this problem is to run the installation with only the primary hard drive and one USB floppy drive hooked up.
If you are unable to disable your extra hard drives, run the SCO OpenServer installation and do the following:
VT0>0:0,7,0: HBA : (usb_msto,1) USB USB HBA
0,0,0: DISK : MITSUMI USB FDD 1039
You should see:
brw-rw-rw 1 root sys 7679,184 Jun 9 13:07 c0b0t0d0p0
When unused space exists before an existing disk partition or between existing partitions, adding a new partition from the installation's Disk Setup screen causes the starting and ending cylinder values of the adjoining partition to be re-assigned. Consequently, any data on the affected partition will become inaccessible.
To avoid this problem, press <Alt><SysReq>h on the Licensing screen to switch to the system console. At the VT0> prompt, run fdisk and define a partition that fills the unused space. Then press <Alt><SysReq><F1> to switch back to the Licensing screen and proceed with the installation.
You can now add a new partition (if still necessary)
from the Disk Setup Partitions screen without affecting
existing partitions and data.

The emergency_rec -e ctape1 command is not working properly, affecting your ability to create an emergency recovery tape.
To fix this problem, edit the /sbin/emergency_rec file and change line 412 to read:
INDEV=/dev/rdsk/${DV}p0

Sometimes when the system enters screen saver mode,
the X server display can become garbled with odd
white and black lines. To fix this, use
<Alt><Ctrl><Fn>
to switch to a different multiscreen, then
<Alt><Ctrl><F2>
to return to tty02 where the X server is running.
Your video display should be back to normal.

Context-sensitive help for the Panorama (xdt3) desktop is not currently working. This problem also affects context-sensitive help for some of the desktop icons, including the Accessories, Controls, Edit, Mail, System Administration, and UNIX icons.
To get help on specific aspects of the Panorama desktop,
please use the DocView Search feature.

The SCO OpenServer online documentation is available via the DocView documentation server. By default, the DocView server starts automatically when the system is booted into multiuser mode.
To determine if the server is running, run /etc/docview. You can also use this command to start and stop the server.
Please note that the ``SCO OpenServer documentation'' section in the Getting Started Guide incorrectly lists the command as /usr/bin/docview.
The Samba documentation includes descriptions and manual pages for features that are not supported by Release 6. These include:
The Internet and Intranet category in the online documentation at http://localhost:8457 does not contain a link to the Apache HTTP Server documentation. To fix this problem, log in to the system as root and:
DocPath=/usr/share/doc/apache/docview_index.fr.htmlso that it reads:
DocPath=/usr/share/doc/apache/index.html.fr
DocPath=/usr/share/doc/apache/docview_index.en.htmlso that it reads:
DocPath=/usr/share/doc/apache/index.html.en
Save and exit the file.
The ``Apache HTTP Server Documentation'' topic
is now available from the Internet and Intranet category
in the online documentation.

When the text on a web page appears too small and unclear, it is probably because of the cascading style sheet (.css file, or CSS) associated with that webpage on the server. The CSS is probably requesting the small type size. Because the browsers shipped with OpenServer do not have a default minimum font size configured, they attempt to match the point size specified by the style sheet.
Users can improve the appearance of all such web pages by setting the browser's minimum font size to 10 point or larger. If you are using Mozilla, select the following from the command menu:
Edit -> Preferences -> Appearance -> FontsIf you are using Konqueror, select:
Settings -> Configure Konqueror -> Fonts
Select 10 point or larger for the minimum font size and then select OK
to set the new value.

There is a problem with the SCOadmin Network Configuration Manager (netconfig) that results in the following error if you change the name of the system:
UX: rpcbind: ERROR: Could not find any loopback transport. Exiting.
To fix this problem, edit the following files:
In each of these files, locate the ``RPC Hosts'' comment and ensure that the following line exists:
sysname sysname
where sysname is the new hostname.
If any of these files are missing this line, add it.
Once these files are corrected, rpcbind will be
able to run successfully.
(532255)
Permissions on certain files that control the IP Filter firewall are set incorrectly.
To fix these permission problems, edit /etc/conf/node.d/ipf and add ``0 0 600'' to the end of each line in the file. The file should look like this when you are finished:
ipf ipl c 0 0 0 600 ipf ipnat c 1 0 0 600 ipf ipstate c 2 0 0 600 ipf ipauth c 3 0 0 600 ipf ipsync c 4 0 0 600 ipf ipscan c 5 0 0 600 ipf iplookup c 6 0 0 600
Then run /etc/conf/bin/idmknod
to recreate the nodes.

If a valid distributed user account is unable to log in to an NIS client, it is possible that the account's password entry in the /etc/passwd and/or /etc/passwd.yp files have become corrupted.
To fix this problem, log in to the NIS master server as root and do the following:
Do the same thing for the /etc/passwd.yp file.
The affected user should now be able to log in to the NIS client.
If you are still having problems after performing the
above steps, you can try to re-initialize NIS.
To do this, put the system into single-user mode and run one
of the following commands:
# mkdev nis
or
# ypinit

Context-sensitive help for the SCOadmin Network Configuration Manager is not currently working. Also, the Help on Keys, Help on Index, and Help on Help options for most of the SCOadmin managers are not working.
To get help on specific aspects of the
Network Configuration Manager,
please use the DocView Search feature.

Because the SCO OpenServer installation uses the ISO8859-1 codeset (which does not contain support for the Euro character), you need to switch to the ISO8859-15 codeset after the installation if you want to display the Euro character.
To configure the system to display the Euro character:
The supported keyboards are:
ps.858.fra
ps.858.ger
ps.858.ita
ps.858.lsp
ps.858.spa
ps.858.ukd
ps.858.usa
For more information,
see ``Selecting codesets'' in the
``Customizing locale settings'' topic,
available from the System Management category
in the online documentation.

If you telnet(TC) to an SCO OpenServer Release 6.0.0 system from a European keyboard, you must use the following commands for the session or 8-bit characters (i.e, the umlaut, Euro symbol, and so forth) will not display.
Note that these steps also apply
if you want to run a telnet session
on the same system to which your European keyboard is attached.

Several of the SCO OpenServer Release 6.0.0 Development System manual
page sections are unavailable after the Development System
product is installed because of a misconfiguration problem.
To fix this problem so that all of the Development System
manual pages are available, complete the Development
System installation and then run the following command:
# /usr/man/bin/makewhatis
See the makewhatis(ADM) manual page for more
information.
