quick tip, research further: -redir tcp:5555:10.0.2.15:3389
[edit] Moving Linux To a new hard disk
1. Install hardisk as slave
2. Make /boot and / partitions as required on the new hardisk
- Use fdisk
3. Use mkfs and format the newly created partitions
- Use mksf.reiserfs for reiserfs
4. Use a linux rescue disk; DO NOT mount old and new harddisk partitions
- Suse linux rescue, login root
5. dd if=/dev/hda6 of=/dev/hdb1
- hda6 = old harddisk boot partition
- hdb1 = new harddisk boot partition
6. Similarly root
dd if=/dev/hda7 of=/dev/hdb2
7. Using Rescue .. Edit /etc/mtab, /etc/fstab, /etc/grub.conf, /boot/grub/menu.lst accordingly
- If suse, grub files might be different for other distros
8. If suse, make sure, /boot/initrd.suse and /boot/vmlinuz.suse point to appropriate initrd and vmlinuz
9. cp /boot/grub/stage1 /usr/lib/
cp /boot/grub/stage2 /usr/lib
10. Run grub-install /dev/hda
- Enjoy.. SKI

[edit] xwiki installation instructions
XWiki Installation Instructions
1. Setup of the XWiki Sample Database
The sample database has been updated for XWiki 0.7/0.9 and is now a good database to start an XWiki installation and is now a SQL dump of an Mysql database.
* MySQL4 SQL Dump: http://prdownloads.sourceforge.net/xwiki/xwiki-db-0.7.460.zip?download
2 Installation Instructions
* Install JDK 1.4.2
* Install Tomcat 4.1
* Verify installation of tomcat on port 8080
* *IMPORTANT* For versioning of international characters to work, you need to launch your tomcat
engine with -Dfile.encoding=iso-8859-1 and add LANG=fr_FR.ISO8859-1 as an environment variable
(Thanks to Erwan Arzur for the tip).
The test database contains international characters so you need these settings.
* Copy xwiki-0-9-xx.war to xwiki.war in the tomcat/webapps directory
* Unzip xwiki-db-0.x.yyy.zip
* Load database using mysql -u xwiki -pxwiki xwiki < xwiki-db-0.x.yyy.txt
* Grant mysql access with the following command:
grant all privileges on xwiki.* to xwiki@127.0.0.1 identified by 'xwiki' ;
(if you get connections problems try localhost instead of the IP address)
* If decide to use a different password or a different machine than the web server machine
for you database, edit hibernate.cfg.xml to change the database configuration.
* Copy your database driver to the tomcat/common/lib directory
* *IMPORTANT*: in xwiki.cfg change the line xwiki.virtual=1 to xwiki.virtual=0
* If you want to use bigger attachments than 1Mb you need to change the packet size setting in Mysql. See http://www.xwiki.org/xwiki/bin/view/Dev/BigAttachments.
* Connect to the xwiki application at: http://127.0.0.1:8080/xwiki/bin/view/Main/WebHome
