Description
Opsi (open pc server integration) is an open source Client Management System for Windows clients.
Key features:
- Automatic OS installation (unattended or image based)
- Automatic software distribution and patch management
- Hardware and software inventories
- License management
Install
Creating necessary repositories
First we need to create the opsi repository:
/sbin/e-smith/db yum_repositories set opsi4 repository \ Name 'CentOS $releasever - $basearch - opsi4.0' \ BaseURL 'http://download.opensuse.org/repositories/home:/uibmz:/opsi:/opsi40/CentOS_CentOS-5/' \ EnableGroups no \ GPGCheck no \ GPGKey http://download.opensuse.org/repositories/home:/uibmz:/opsi:/opsi40/CentOS_CentOS-5/repodata/repomd.xml.key \ Visible no \ status disabled
We also want to add the DAG repository for the needed python-rrdtool package (and sadly also a LOAD of other dependencies that come with python-rrdtool):
/sbin/e-smith/db yum_repositories set dag repository \ Name 'Dag - EL5' \ BaseURL 'http://apt.sw.be/redhat/el5/en/$basearch/dag' \ EnableGroups no \ GPGCheck yes \ GPGKey http://dag.wieers.com/packages/RPM-GPG-KEY.dag.txt \ Visible no \ Exclude freetype,htop,iptraf,rsync,syslinux \ status disabled
Then to activate the newly added repositories:
signal-event yum-modify yum makecache
Installing the packages
Installing the necessary Opsi packages.
yum install opsi-depotserver opsi-configed --enablerepo=opsi4,dag /etc/init.d/opsiconfd restart /etc/init.d/opsipxeconfd restart yum install p7zip p7zip-plugins cabextract --enablerepo=opsi4 yum update --enablerepo=opsi4
Manual code change
An manual adjustment to the code needs to be made for Opsi to work on SME.
nano /usr/lib/python2.4/site-packages/OPSI/Backend/BackendManager.py
Search for the following line:
elif (DISTRIBUTOR.lower().find('redhat') != -1) or (DISTRIBUTOR.lower().find('centos') != -1) or (DISTRIBUTOR.lower().find('scientificsl') != -1):
And replace it with:
elif (DISTRIBUTOR.lower().find('redhat') != -1) or (DISTRIBUTOR.lower().find('centos') != -1) or (DISTRIBUTOR.lower().find('scientificsl') != -1) or (DISTRIBUTOR.lower().find('sme') != -1):
Opsi init
Some initialization for Opsi.
opsi-setup --init-current-config opsi-setup --set-rights /etc/init.d/opsiconfd restart /etc/init.d/opsipxeconfd restart
Set pcpatch password
Make a note of the password you are setting, you might need it later.
opsi-admin -d task setPcpatchPassword
Java config
Add a symbolic link for the installed java runtime environment:
ln -s /usr/lib/jvm/java-1.6.0-sun-1.6.0/jre/bin/java /usr/bin/java
Check the java version, this sould now return a result
java -version
User config
Opsi normally uses separately created users for administration, but for SME we use the default admin account. Add the admin account to the opsiadmin group so it can use the Opsi administration commands.
usermod -a -G opsiadmin admin
It is not neccesary to add the root account to the pcpatch group, root is allowed to do anything. If you want a separate user to be able to build opsi packages (opsi-makeproductfile), install packages (opsi-packagemanager) or manually edit configuration files, it would have to be added to the 'pcpatch' group.
#usermod -a -G pcpatch <some_user>
Opsi-atftpd config
Add a sysconfig file for atftpd.
nano /etc/sysconfig/atftpd
Add the following content to this file:
ATFTPD_OPTIONS="--daemon --user atftp --group atftp --logfile /var/log/atftp/atftp.log /tftpboot"
Create an atftpd startscript:
nano /etc/rc.d/init.d/atftpd
Add the following content to this file:
#!/bin/sh
#
# atftp Advanced Trivial File Transfer Protocol
#
# chkconfig: - 90 20
# description: atftp stands for Advanced Trivial File \
# Transfer Protocol. atftp is intended for serving boot files to \
# large clusters. It is multi-threaded and support multicast \
# (RFC2090 and PXE), allowing faster boot of hundreds of machine simultaneously.

Add a template fragment for the opsi samba network shares:
mkdir -p /etc/e-smith/templates-custom/etc/smb.conf nano /etc/e-smith/templates-custom/etc/smb.conf/51opsi_shares
Add the following content to this file:
[opt_pcbin]
available = yes
comment = opsi depot share
path = /opt/pcbin
oplocks = no
level2 oplocks = no
writeable = yes
invalid users = root
[opsi_config]
available = yes
comment = opsi config share
path = /var/lib/opsi/config
writeable = yes
invalid users = root
[opsi_workbench]
available = yes
comment = opsi workbench
path = /home/opsiproducts
writeable = yes
invalid users = root
create mask = 0660
directory mask = 0770
Expand the template:
expand-template /etc/samba/smb.conf
Restart samba services:
/etc/rc7.d/S91smb restart
Notes
Internal Error on agent deploy
When you get an 'internal error' on trying to install an agent on a workstation from the commandline with the opsi-deploy-client-agent command, you probably have the bad version of winexe, so you'll need to get the newer version from UIB:
cd /opt/pcbin/install/opsi-client-agent/ mv winexe winexe.OLD wget http://download.uib.de/opsi3.4/winexe chmod --reference ./winexe.OLD winexe chown --reference ./winexe.OLD winexe
Windows firewall exceptions
On windows machines you need to enable the "File and printer sharing" exception for the windows firewall. On occasion it could also be necessary (after some Windows update) to re-add the 'opsiclientd-control-port' TCP-port: 4441 or add the opsiclientd (usually in: C:\Program Files\opsi.org\opsi-client-agent\opsiclientd.exe) to the Windows Firewall exceptions for "On Demand" installations to work.
