Network configuration
Migrating Hardware Configuration
 The new SVR5 kernel should recognize and automatically
configure all your hardware devices – you no longer need
to manually configure hardware devices
 Sound Cards:
 only Intel ICH4 and prior chipsets that comply with the AC’97
standard are supported at this time – they will be detected and
automatically configured at boot
 Printers:
 use the Printer Manager to re-create your printer setup
4
Migrating Hardware Configuration
 Serial Cards:
 All supported serial cards are now auto-detected at boot, you no
longer need to add or configure them in the Serial Manager
 However, you must run the Serial Manager at least once to
create the devices nodes and configure the ports controlled by the
serial cards before you can start using them
 Serial cards with 3rd party drivers will need a new SVR5 driver
 Modems:
 Configured as usual through the Modem Configuration
Manager
 PC Card (PCMCIA) modems must be configured using the DCU
5
Migrating Hardware Configuration
 Mass Storage Devices:
 should be auto-detected and configured at boot time – use the
DCU to configure HBAs that were not auto-detected
 use mkdev hd to view detected hard disks and configure
filesystems on them (or run fdisk and divvy manually)
 use mkdev cdrom to view detected CD-ROM drives
 use mkdev tape to view detected tape drives. Most tape drives
supported on OSR5 are also supported on OSR6 except some
floppy-tape (QIC-80) devices
6
Migrating Hardware Configuration – Device Nodes
 In general OSR6 supports both OSR5-style and SVR5-style
(UnixWare) device nodes
 For hard disk nodes, a combination is used:
 Partitions are OSR5-style:
/dev/[r]hdXY
/dev/dsk/XsY
X is the physical disk number
Y is the partition number
 Divisions (slices) are SVR5-style:
/dev/[r]dsk/cXbXtXdXsZ
/dev/[r]dsk/cXbXtXdXpYsZ
X is the SCSI address as output by /etc/scsi/sdiconfig –l
Y is the partition number
Z is the division (slice) number
7
Migrating User Accounts

Archive accounts and group membership on the OSR5
system:
ap –d -g –v > profile.acct

Restore the accounts on the OSR6 system. OSR5 and
OSR6 treat long passwords differently, so there are two
methods for restoring your account details:
1. truncate the long passwords to 8 characters:
ap –r –f profile.acct
2. specify a new default password for all accounts with long
passwords only:
ap –r –f profile.acct –p password
8
Migrating Mail
 User inboxes:
 copy /usr/spool/mail from OSR5 to /var/mail on the OSR6 system
 MMDF configuration:
 copy only the following files from OSR5 to the OSR6 system:
/usr/mmdf/mmdtailor
/usr/mmdf/table/*.chn
/usr/mmdf/table/*.dom
/usr/mmdf/table/alias.*
/usr/spool/mmdf/lock/home/q.*
 on the OSR6 system, enter the following commands:
su mmdf
cd /usr/mmdf/table
./dbmbuild
exit
9
Migrating Mail
 SendMail configuration:
 merge the contents of the OSR5 configuration files with
the new OSR6 files, do not simply copy them:
10
OSR5
OSR6
/usr/lib/sendmail.d/access
/etc/mail/access
/usr/lib/sendmail.d/aliases
/etc/mail/aliases
/usr/lib/sendmail.d/domains
/etc/mail/domaintable
/usr/lib/sendmail.d/local-hosts-names
/etc/mail/local-hosts-names
Migrating Mail
 To preserve vacation notifications and custom
forwarding, copy the following files from each user’s
home directory
 MMDF:
~/.maildelivery
~/.alter_egos
~/tripnote
~/triplog
 SendMail:
~/.forward
~/.vacation.msg
11
Migrating User Data
 You can migrate your user data either via a backup tape or
mounting the existing OSR5 disk on OSR6
 Creating a backup tape is the recommended method
because it allows you to restore to a VxFS filesystem and
take advantage of large file support
 Either use a 3rd party backup solution that is supported on
both platforms (eg. BackupEdge or LoneTar) or use the
cpio command
 To restore an OSR5 cpio archive on OSR6:
cpio –iAmudB –I<backup_device>
12
Migrating User Data – Mount OSR5 disk
 To mount an existing OSR5 disk (5.0.6 or 5.0.7
only), you must first install the wd Supplement on
the OSR5 system
 Connect the drive to the OSR6 system
 After booting, login as root and run the command
getlclfsdev to determine the /dev/dsk device
nodes for the filesystems on the disk
 Use the Filesystem Manager to mount the
filesystems
13
Migrating Networking
 The loopback interface is no longer presented in the
Network Configuration Manager
 The “Add New WAN Connection” menu item has been
removed from the Network Configuration
Manager
 SCO PPP is no longer supported, PPP is provided by
Morning Star PPP
 SLIP is no longer supported
 Netware and IPX/SPX are no longer supported
14
Migrating Networking: TCP/IP
 On the OSR5 system, use the netstat –rn command and note
the hostname, domain name, IP address, netmask, broadcast
address and frame type of the existing network interfaces
 On the OSR6 system, enter these values at ISL or via the
Network Configuration Manager after ISL
 Migrate the following configuration files (merge with existing
files, do not simply copy):
15
/etc/hosts
Hostnames and IP addresses
/etc/default/tcp
TCP/IP configuration file
/etc/tcp
TCP/IP configuration file
/etc/inetd.conf
Services available through inetd
Migrating Networking: DHCP
 To migrate your DHCP Server configuration, copy
/etc/inet/dhcpd.conf to the OSR6 system
 To migrate your Address Allocation Server (AAS)
configuration, copy /etc/inet/aasd.conf to the
OSR6 system
16
Migrating Networking: Routing
 gated and routed have been updated in OSR6. The new routed adds
RIPv2 support and both can do router discovery
 The new command rtquery allows you to query the routing daemons
and provides additional control over routed
 Migrate the following configuration files:
17
/etc/gated.conf
gated configuration – do not simply copy, changes
are needed, see gated.conf(SFF)
/etc/gateways
routed configuration, copy to /etc/inet/gateways –
supports many more keywords, see routed(ADMN)
/etc/gated.bgp
BGP configuration
/etc/gated.egp
EGP configuration
/etc/gated.ospf
OSPF configuration
/etc/gated.rip
RIP configuration
Migrating Networking: DNS
 DNS has been updated to BIND 8.4.4 in OSR6,
which includes security fixes and new features
 Copy the following configuration files:
/etc/named.conf
named configuration
/etc/resolv.conf
Resolver configuration
/etc/named.d/*
DNS data files
 Then use the ndc restart command to restart
named
18
Migrating NIS
 NIS is unchanged in OSR6
 There are no configuration files to migrate over
(assuming you already migrated over the user
accounts using ap).
 Run the ypinit command to configure NIS:
-m
-s master
-c master
-C
19
configure as

Migrating UUCP
 UUCP is unchanged in OSR6
 Copy the following configuration files:
/usr/lib/uucp/Devices
/usr/lib/uucp/Permissions
/usr/lib/uucp/Poll
/usr/lib/uucp/Systems
20
Migrating an FTP Server
 ftpd has been updated to version 2.4 in OSR6, it includes
security fixes and additional features
 New FTP Server Manager can be used to configure ftpd
 Migrate the following configuration files:
21
/etc/ftpusers
merge with existing file in OSR6
/etc/shells
merge with existing file in OSR6
/etc/ftpconv
merge with existing file in OSR6
/etc/ftpaccess
syntax has changed for:
private keyword
upload keyword
Migrating NFS



22
NFS has been updated to NFSv3 in OSR6, its substantially different from the
NFSv2 in OSR5
automount no longer looks at the NIS auto.master map file unless the
following line is added to /etc/auto.master
+auto.master
Use the information in the OSR5 configurations files to edit the OSR6 files, you
cannot simply copy the configuration files from OSR5 to OSR6:
/etc/default/filesys
Used by client to define the systems to be mounted.
The device names will differ on OSR6.
/etc/exportfs
Used by the server to define filesystems that clients
can mount. The device names will differ on OSR6.
/etc/auto.master
Lists initial automount configuration
/etc/auto.direct
Lists direct automount configuration
/etc/auto.indirect
Lists indirect automount configuration
Migrating NTP
 NTP is basically the same on OSR5 and OSR6
 The default configuration file (ntp.conf) is the
same on both platforms, but is now located in
/etc/inet/ntp.conf instead of /etc/ntp.conf
 You will also need to copy over any files containing
authentication keys and create any log files
defined in ntp.conf
23
Migrating PPP



SCO PPP has been replaced by SCO Morning Star PPP
There is no graphical administration tool for Morning Star
PPP
If you were already using Morning Star PPP on OSR5, you
can simply copy the following files:
/usr/lib/mstppp/Autostart
/usr/lib/mstppp/Accounts
/usr/lib/mstppp/Auth
/usr/lib/mstppp/Systems
/usr/lib/mstppp/Devices
/usr/lib/mstppp/Dialers.local
/usr/lib/mstppp/exec.in/*
/usr/lib/mstppp/exec.out/*
24
Migrating PPP
 To migrate from SCO PPP to Morning Star PPP, save the
following files from the OSR5 system for reference:
/etc/ppphosts
/etc/pppauth
 For outbound connections:
 use the host entries in the OSR5 /etc/ppphosts file when editing
the /usr/lib/mstppp/Systems OSR6 file
 use the PAP/CHAP information in the OSR5 /etc/pppauth file for the
/usr/lib/mstppp/Auth OSR6 file
 For inbound connections:
 use the host entries in the OSR5 /etc/ppphosts file when editing
the /usr/lib/mstppp/Accounts OSR6 file
 use the PAP/CHAP information in the OSR5 /etc/pppauth file for the
/usr/lib/mstppp/Auth OSR6 file

Changes – ISL
 OSR6 uses the “no-emulation” boot cd method instead of
“floppy-emulation” – may not work with very old systems
that only support floppy-emulation
 Supports installing above 1024 cylinders/8GB boundary
 Prompts for installing additional HBAs during ISL
 Supports HBAs on CDs in addition to floppies
 Can defer licensing to get an eval license (press <F8> on
the license screen)
 A mouse can be configured and tested during ISL
 The date and time can be set during ISL
 Video cards are no longer configured during ISL, they are
autodetected and configured on first reboot
27
Changes – System Startup
 OSR6 autoboots by default with a [boot] prompt with a twentysecond countdown instead of the Boot: prompt in OSR5
 A graphical SCO OpenServer Release 6 logo replaces the hwconfigstyle hardware listing
 /etc/inittab is built from /etc/conf/init.d/kernel instead of
/etc/conf/cf.d/init.base
 OSR6 is SMP-ready out of the box




Auto-detects multiple CPUs at boot
Licensing controls how many can be utilized
Hyper-threaded and multi-core CPUs need just one license
Enter PSM=atup at the boot prompt to force uni-processor only
 NOTE: the /etc/default/boot parameters have changed considerably,
see boot(HW) for details
28
Changes – Kernel
 Dynamically loadable drivers:
 Allows loading of drivers without a kernel relink and reboot
 modadmin -s lists the loaded drivers
 modadmin -l mod_name loads a driver
 Drivers are located in /etc/conf/mod.d
 Kernel linking is deferred by default until reboot, use
/etc/conf/bin/idbuild -B to build the kernel immediately
 Kernel is autotuned based on the amount of memory detected
at boot
 OSR5 drivers will not work with the new kernel, must use SVR5
drivers
 /dev/table and /dev/strings no longer present, use hw(ADM)
and sdiconfig(ADM) to view hardware configuration
29
Changes – Kernel
 scodb has been replaced with the kdb kernel
debugger
 Managing multi-processors has changed:





30
psradm(ADM) for processor configuration
psrinfo(ADM) for displaying processor information
rtpm(ADM) for performance monitoring
pbind(ADM) for locking a process to a specific CPU
processors are numbered from 0 instead of 1
Changes – Console
 Console termtype has changed from scoansi to
at386-ie
 Applications with “hard wired” scoansi escape
sequences will not work directly on the OSR6
console (but will work in a scoterm or remote login
from an OSR5 system)
 Applications that use terminfo/termcap will work
just fine
31
Changes – X Server
 OSR6 has a brand new X Server: X.org X11R6
 It is configured via /etc/xorg.conf
 Most video cards are automatically detected and the X
Server attempts to use the highest possible resolution for
your video card and monitor
 If you are having trouble getting the X server to run at a
good resolution, try editing /etc/xorg.conf to enter the
exact horizontal and vertical refresh rates for your monitor:
Section “Monitor”
HorizSync
31.5 – 60
VertRefresh 40 - 60
32
Changes – Desktops
 In addition to the OSR5 xdt3 desktop, OSR6 has the new
KDE desktop
 xdt3 desktop is the default
 Switch to the KDE desktop for all users by changing
XDESKTOP in /etc/default/X11:
XDESKTOP=kde3
 Individual users can specify their desktop preference by
setting XDESKTOP in their shell startup scripts
 Valid values are “xdt3” or “kde3” – they are defined in
/etc/default/xdesktops, so you can add additional desktop
options to this file
33
Changes – Filesystems
 OSR6 updates support for the following filesystems:






VxFS (new – supports large files, the default root filesystem)
HTFS (updated – journaling and versioning no longer supported)
CDFS (replaces HS filesystem, updated to support Joliet)
DOSFS (updated to support FAT32 and VFAT)
MEMFS (new – memory/RAM filesystem)
NFS (updated to v3)
 All the filesystems now support up to 16 divisions per
partition and can be encrypted via the new -c option to the
marry(ADM) command
 The DTFS and XENIX filesystems are no longer supported
34
Changes – Filesystems
 The Virtual Disk Manager is no longer supported
 AFPS is no longer supported, it has been replaced by
Samba
 divvy now supports up to 15 user-defined divisions on
each partition
 badblk & badtrk commands removed, their operations
are now handled transparently by the system
 dparam & dkinit commands removed, you can no longer
change or override the hard disk parameters, they will
always be as set by the system BIOS
35
Changes – Large File Support
 Only supported on the VxFS filesystem
 Enabled by default
 Commands that are Large File Aware:
cat(1), du(1), pathchk(1), chgrp(1), ff(1M)

information only
 See also the “OSR6 Diagnostics and Troubleshooting”
presentation (Room 103, 3pm Tues)
38
Changes – Web
 Netscape FastTrack Server no longer supported,
replaced by Apache 1.3
 Netscape Communicator no longer supported,
replaced by Mozilla
39
Changes – Commands
 OSR6 distributes basic system commands into three main
directories:
/bin
commands inherited from OSR5
/u95/bin
commands that conform to the UNIX95
standard, including LFS support
/udk/bin
commands inherited from UW7
 For different behaviors, set your PATH as follows:
/bin
Traditional OSR5 user
/u95/bin:bin
OSR5 user who wants LFS support
/udk/bin:/u95/bin:/bin User running UW7 apps
40
Changes – Documentation
 Online documentation no longer organized by
books, but by topics, which allows for tighter
integration of third-party documentation
 DocView can now print an entire topic instead of
just a single section
 select which sections you want and DocView will display
all the selected sections as one page for printing from
the browser
 can also elect to generate a PDF or postscript file
41
Configuring new features
•
•
•
•
•
CUPS
Samba
mySQL
PostgreSQL
Multi-path I/O
Configuring CUPS Printers
 To use just CUPS:
 edit /etc/default/lpd
PRINTER_SYSTEM=CUPS
 the Printer Manager will automatically launch the CUPS web-based
administration tool
 login as root and use root’s password
 To use both CUPS and SYSV lp (default) :
 edit /etc/default/lpd
PRINTER_SYSTEM=SYSV
 the Printer Manager will manage the SYSV lp printers and to configure
CUPS printers, enter the following URL in a browser:
http://localhost:631
 login as root and use root’s password
 NOTE: the CUPS administration tool only allows alpha-numeric
characters in the password, so you will have to change root’s password
if it contains non-alphanumeric characters
43
Configuring Samba
 Initial configuration is done via mkdev samba:




workgroup name
WINS configuration
Security Domain or Active Directory configuration
Enable and activate Samba daemon
 The Samba configuration file can be found in
/etc/samba/smb.conf
 For much more info, go to the “Installing and
Configuring Samba 3” presentation
(Room 104, 10:15am Tues)
44
Configuring mySQL
 Initial configuration is done via mkdev mysql:




define the mysql database owner and password
enable/disable the server
stop/start the server processes
define the database location and initialize the database
 The mysql(1) command provides a curses-based client for
connecting to a mySQL database
 The mysqladmin(1) command provides some
administration options
 The mySQL configuration file can be found in /etc/my.cnf
45
Configuring PostgreSQL
 Initial configuration is done via mkdev pgsql:




46
define the postmaster owner and password
enable/disable the server
stop/start the server processes
define the database location and initialize the database
Multi-Path I/O
 MPIO allows multiple HBAs to be connected to the same
hard disk
 Usually requires either a dual-ported device or some form
of networked storage
 Provides redundancy, availability and load balancing
 A path is associated with a disk stamp and SCSI address
 OSR6 recognizes if a target has multiple access paths by
enumerating different disk SCSI addresses with the same disk
stamp
 Disabled by default, turn on with mkdev mpio
 Administered using sdipath(ADM)
