Summary of an Installation and Migration – Start Point


Summary of an Installation and Migration – Temp OES Server Added


Summary of an Installation and Migration – Migration Complete


Live Demo

• Let's go...

Linux Overview


Background

• First version in 1991

• Linux is technically just the kernel– Requires the GNU utilities– Hence the full name GNU/Linux


What Do You Mean, Free?

• No restrictions: libre

• Costs no money: gratis

• General Public License (GPL)– Four Freedoms: Use, Study, Redistribute, Change– Changes and improvements must remain free (unlike BSD

licence)

• Open Source software is free but can still be charged for

– e.g.SUSE® Linux Enterprise Server, Red Hat, etc


openSUSE® and SUSE® Linux Enterprise• openSUSE

– Open Source project sponsored by Novell®

– Developed by Novell and the community– Free (gratis), free (libre) and unsupported by Novell– At the leading edge– Once openSUSE has matured and stabilised...

• SUSE Linux Enterprise (SLE)– Commercial release– Paid for by subscription and supported by Novell– Some proprietary extras


SUSE® Linux Enterprise Server Platform Support• x86

• x86_64 (AMD64 and Intel EM64T)

• IA64 (Itanium 2)

• IBM POWER

• IBM System z (64-bit)

OES Overview


Background

• SUSE® Linux running NetWare® services– ...And some new ones

• Proprietary, not free

• Looks just like NetWare to users

• OES1 released in March 2005

• OES2 released October 2007


Platform Support

• x86

• x86_64 (AMD64 and Intel EM64T)


Version Control

• Cannot mix and match– OES2 SP1 requires SLES10 SP2– OES2 SP2 requires SLES10 SP3– ...etc

Problems, Problems, Problems


The Biggest Problem With Linux is...?



• Choice!



• Which one is better?

• Which one is right?

• Which one would Novell® recommend?

• Which one do you like best?

...If you ask ten people, how many different answers do you think you will get?


Is NetWare® Any Better?


GNOME Desktop

• GNU Network Object Model Environment

• Focus on usability and simplicity

• Default desktop with SLES and OES

• Runs on X Windows


KDE Desktop

• K Desktop Environment

• Feature-rich

• Can be installedinstead of GNOME(or as well as)

• Runs on X Windows


File Systems: ReiserFS

• Advantages– Simple, quick, stable– Good performance and recovery– Efficient disk usage– Best with many small files

• Disadvantages– Only supports metadata journalling– Repair tools not very robust– Not so good with large files


File Systems: EXT3

• Advantages– Quick, stable– Handles large files well– Supports metadata journalling and data writes

• Disadvantages– Does not scale well to large volumes– Does not scale well to many (>500 per directory) small files


File Systems: NSS

• Advantages– Very rich metadata (rights model)– Salvage, compression, shredding, snapshots, user quotas

• Disadvantages– So many features may present an overhead

The Basics


Scalability and Resilience

• OES NetWare®

– 32 Bit - 4 Gb address space– Most code executes in Ring 0– Some code executes in protected memory

• OES Linux– 32 Bit - 4 Gb address space– 64 Bit - Huge address space– Most code executes in protected memory– Some code executes in Ring 0


Code

• OES NetWare®

– NetWare Loadable Module (NLM)– Both programs and libraries are modules– .NCF Scripts (also .BAS, etc)

• OES Linux– Binary Executables (no extension)– Shared Libraries (.so)– .sh scripts (also, .py, etc)


File Extensions

• A DOS/Windows thing– Extensions mean something to the Operating System

• Not widely used in Linux– A document called mytext.doc could be a spreadsheet

• A lot of conventions exist– e.g. .sh for shell script– e.g. .py for Python script– ...But you still don't need them


Just in Case

• Linux is case sensitive– cd /home/syd/music will workCD /home/syd/music will fail

– /home/syd/ and /home/SYD are different

• Everything!– File/Pathnames, commands, scripts...– ...Switches and parameters can mean different things

depending on their case

• If a command doesn't go according to plan– Check, check and then check again


Slash

• DOS, Windows and NetWare®

– Back slash: \ or Forward slash: /– e.g.edit sys:\etc\hosts

edit sys:/etc/hosts

• Linux– Forward slash only: /– e.g.edit /etc/hosts


Dot

• Novell® eDirectory™ on Windows and NetWare®

– NDAP format with dots:– e.g.cn=Syd.ou=Darkside.O=TheMoon

• eDirectory on Linux– LDAP format with commas:– e.g.cn=Syd,ou=Darkside,O=TheMoon

• There may be inconsistencies– If it doesn't work, try the other way!


Who's The Daddy?

• OES has two all-powerful superusers:– Linux: root– eDirectory: Admin

• Use sudo to run a single command as root

• Use su (or su -) to switch to root

• Do not login as a superuser for day-to-day activities

• Do not bring bad habits with you!


Logging In

• Console

• ssh


Who Knows Who is Who?










sudo -Elevated Privileges by Proxy


Moving Around

• 8 default consoles (tty)

• Switch Screens– Text Consoles: <CTRL><ALT><F1> ... <F6>

– Graphical Console: <CTRL><ALT><F7>

– Error Messages: <CTRL><ALT><F10>

The Big Differences


Disk Naming

• Controller– SCSI: sdx– IDE: hdx

• Disks– a, b, c, etc– e.g. sda, sdb, hda, etc

• Partitions– 1, 2, 3, etc– e.g. sda1, sda2, sdb1, etc

sda sda1

sda2

/

swap

sdb sdb1

/home

Where is Everything?

• System directories/ (The root directory)/bin /boot/dev /etc/home /initrd/lib /lost+found/media /mnt/opt /proc/root /sbin/usr /var/srv /tmp

• http://www.tldp.org/LDP/Linux-Filesystem-Hierarchy/html/index.html


Mount Points

• Any directory can be a mount point– Another device; e.g. hard disk, iPod, USB, etc– Remote network; e.g. CIFS, NFS, etc– Comparable to Distributed File System (DFS) on NSS

• e.g. mount /dev/sdc1 /mnt

• / (root) is comparable to SYS: on NetWare®

– Keep it on its own disk, just like SYS: on NetWare

Everything in the File System

• /dev

– Maps devices to files

• /proc

– Similar to the NetWare® virtual _admin: volume– e.g.cat /proc/diskstats

cat /proc/meminfo


/proc


Up and Down

• Runlevels– init 0 aka shutdown– init 1 Single user, no network, no services– init 2 Multiuser, network, no services– init 3 Multiuser, network, services– init 4 Not used/user defined– init 5 Multiuser, network, services, X Windows– init 6 aka reboot

• Server usually runs in runlevel 3 or 5


Start and Stop

• /etc/init.d/<service name> start|stop|status|...– Just text files – have a look! (use cat or more)– e.g./etc/init.d/tomcat5 stop

• service <service name> start|stop|status|...– Borrowed from RedHat– e.g.service tomcat5 start

• rc<service name> start|stop|status|...– SUSE-Specific– e.g.rctomcat5 status


Error Logs

• Main logs– /var/log/messages– /var/log/boot.msg

• Program-specific– /var/log/*– e.g. /var/log/apache2/error_log

• Other– Refer to the documentation– e.g. /var/opt/novell/log/*


Configuration Files

• Main configuration files– /etc/* and subdirectories– e.g. /etc/ntp.conf

/etc/iscsi/iscsid.conf/etc/opt/novell/ncp/ncpserv.audit.conf

• Application-specific– Refer to documentation– e.g. /var/opt/novell/ncs


Users

• NetWare® – eDirectory™

– Hierarchical– Distributed– Encrypted Database

• Linux – Password Repository– Flat– Server-centric– Text file with encrypted entries (/etc/shadow or /etc/passwd)

• Integrate using LUM (more on that later)


NSS File Rights and Permissions

• NetWare® Rights– SRWCEMFA– Assigned to users, groups and containers– rights.exe, etc

• NetWare Attributes– AciDcDiDmHIcNPRiRoRwShSyTX– Assigned to files and directories– flag.exe, etc


Linux File Rights and Permissions

• Linux Rights– RWX– Assigned to a user, a group and everyone– chmod– e.g.chmod 644 diamond.txt

• Linux ACLs– setfacl, getfacl– Not really needed in an OES context


Permissions and Ownership

• -rw-r--r-- 1 mgould users 21 2010-02-03 14:10 diamond.txt




r w x r w x r w x

mgould users Everyone Else


File Ownership

• NetWare®/NSS owner (aka creator)– iManager

• Linux owner– chown

e.g.chown mgould diamond.txt– chgrp

e.g.chgrp users diamond.txt


Running Scripts and Executables

• Explicit path– e.g./sbin/myapp

• Relative path– e.g../myscript.sh– myscript.sh on its own won't work

• Check execute and owner– e.g.Can Syd execute this?-rwxrw-r-- 1 mgould users 98 2010-02-03 14:12 crazy.sh


File Formats

• Carriage Returns and Line Feeds– Do not use DOS/Windows editors– Handled differently– dos2unix

• Check with a hex editor– e.g.okteta


Not Part of OES Linux

• IPX

• Traditional Volumes

• Timesync

• iFolder 2

OES Services


eDirectory™

• ndsd daemon– List instances: ndsmanage

– DSRepair: ndsrepair

– DSTrace: ndstrace

• Default directories– Dibset: /var/opt/novell/eDirectory/data/dib– Binaries: /opt/novell/eDirectory/– Config: /etc/opt/novell/eDirectory/conf/nds.conf– Logs: /var/opt/novell/eDirectory/log/


Novell® Storage Services (NSS)• novell-nss kernel module

– Also ncp2nss– NSSMU: nssmu

– NSS Console: nsscon

• Mounted in Linux– /media/nss/<Volume_Name>

• Default directories– Binaries: /opt/novell/nss– Config: /etc/opt/novell/nss/nssstart.cfg

/etc/opt/novell/ncp2nss.conf– Logs: /var/opt/novell/log/ncp2nss.log


Novell® Core Protocol (NCP™)

• Runs as part of eDirectory™ (ndsd)– 'MONITOR': ncptop

– NCP Console: ncpcon

• Default directories– Binaries: /opt/novell/ncpserv– Config: /etc/opt/novell/ncpserv.conf– Logs: /var/opt/novell/log/ncpserv.log


Novell® Core Protocol (NCP™)

• Make Linux volumes available via NCP– ncpcon:create volume <NCP Vol> <Linux Dir>– e.g.create volume ncpdata /data/stuff– NoRM

• Why use NSS, then?– Scalability limited to underlying file system– Lacks NSS features like salvage, compression, shredding, etc


Linux User Management (LUM)

• Allows local Linux users to be managed via, and interface with, eDirectory™

• Optional but required by iPrint, NSS, etc– e.g.To see correct owner, modifier, deleter and archiver of a file

• Administration via iManager and YaST

• The defaults will work for this demonstration


Compatibility

• Many Legacy tools should still work

• ...But not necessarily supported!– DOS command-line Tools– DOS C-Worthy Tools– Windows Tools– NWAdmin– ConsoleOne®

Linux Tools and Commands


RTFM!

• Read The Free Manuals

• All commands should have a man page

• Man pages– man <command>

– e.g.man ndsrepair– http://www.linuxmanpages.com/


man


More Free Information

• Info pages– info <command>

– e.g.info cp

• Many commands have an info page


info


Yet Another Setup Tool - YaST

• Similar to Windows Control Panel

• Easy to use

• Hides command lines, parameters and complexity

• Configure all aspects of SLES and OES

• GUI or text versions

• ...If in doubt how to configure the system, check YaST!


YaST


YaST


Handy Commands

• Don't forget: man <command>

• Navigating directories– mkdir (md), chdir (cd), rmdir (rd)– ls (dir) best used with -la parameter

i.e. ls -la

• Manipulating files– cat

– tail

– vi (edit)


Handy Commands

• Don't forget: man <command>

• Manipulating files– cp

– mv

– rm


Handy Commands

• Watching processes– top

– kill <PID> (or kill -9 <PID> if it just won't die)– ps (try ps -eaf)

• Manipulating disks– mount

– fdisk (try fdisk -l)– fsck

OES Tools and Commands


Handy Tools

• Server-based tools– You must be the root user to use these tools– NCP™: ncptop, ncpcon– NSS: nsscon, nssmu, ravsui– Trustees & attribs: rights, attrib, metamig– eDirectory™: ndstrace, ndsrepair

• Browser-based tools– You must have sufficient eDirectory rights to use these tools– iMonitor, iManager, NoRM

Migration Utility


Types of Migration

• Consolidate– Reorganise resources

e.g.File, print, AFP, CIFS, DHCP, iFolder, etc– One-to-one or many-to-one– Same tree or different tree (not CIFS, AFP)

• Transfer ID– Transfer server identity from source to target– Includes name, IP address, eDirectory™ replicas, NICI keys,

certificates, etc– Same tree only


The Migration Tool Utility

• Check the documentation– Print this:http://www.novell.com/documentation/oes2/pdfdoc/mig_tools_lx/mig_tools_lx.pdf

• Check the prerequisites– Consolidation: Page 51 Transfer ID: Page 59

• Do a test run– Then do another test run– Ensure you have a good backup before doing it for real


miggui - The Migration Tool Utility

Troubleshooting


Find the Error Message

• Check the logs– There are lots of logs

• Check the case and syntax– Then check again

• Check permissions and ownership– Is it executable? Do you have permission to execute it?

• Don't abandon what you already know– Comms, eDirectory™, DNS, naming, location
