2. download hamachi and quamachi, ex:
http://quamachi.googlecode.com/files/quamachi-0.4.1-1.package
http://quamachi.googlecode.com/files/hamachi-0.9.9.9-20.package
3. sudo apt-get install python libqt4-core python-qt4 pyqt4-dev-tools upx-ucl grep bash make
4. chmod 777 hamachi-0.9.9.9-20.package

7. sudo ./quamachi-0.4.1-1.package

rsync -C or --cvs-exclude

rsync -C option excludes .exe files by default so if you want to rsync .exe files add in
--include=*.exe

Which filetypes does cvs ignore? Then.. which filetypes does rsync ignore ontop of the cvs ignores. From man pages (man rsync):

-C, --cvs-exclude
This is a useful shorthand for excluding a broad range of files that you often don’t want to transfer between systems. It uses a similar algorithm to CVS to determine if a file should be ignored.


The exclude list is initialized to exclude the following items (these initial items are marked as perishable — see the FILTER RULES section):


RCS SCCS CVS CVS.adm RCSLOG cvslog.* tags TAGS .make.state .nse_depinfo *~ #* .#* ,* _$* *$ *.old *.bak *.BAK *.orig *.rej .del-* *.a *.olb *.o *.obj *.so *.exe *.Z *.elc *.ln core .svn/ .git/ .bzr


then, files listed in a $HOME/.cvsignore are added to the list and any files listed in the CVSIGNORE environment variable (all cvsignore names are delimited by whitespace).


Finally, any file is ignored if it is in the same directory as a .cvsignore file and matches one of the patterns listed therein. Unlike rsync’s filter/exclude files, these patterns are split on whitespace. See the cvs(1) manual for more information.


If you’re combining -C with your own --filter rules, you should note that these CVS excludes are appended at the end of your own rules, regardless of where the -C was placed on the command-line. This makes them a lower priority than any rules you specified explicitly. If you want to control where these CVS excludes get inserted into your filter rules, you should omit the -C as a command-line option and use a combination of --filter=:C and --filter=-C (either on your command-line or by putting the “:C” and “-C” rules into a filter file with your other rules). The first option turns on the per-directory scanning for the .cvsignore file. The second option does a one-time import of the CVS excludes mentioned above.

please mount the unreal tournament play disc cdrom - ut2004 on ubuntu fix

I was trying to install ut2004 on ubuntu and kept getting the message:
"please mount the unreal tournament play disc cdrom"

I think because ubuntu auto-mounts volumes, it mounts them in multiple places, somehow confusing the installer. The answer is to umount it... then manually mount it below as shown.

sudo apt-get install libgtk1.2
umount /media/cdrom
sudo mount /dev/cdrom /media/cdrom
export SETUP_CDROM=/media/cdrom
/media/cdrom/linux-installer.sh
... let it install ...
umount -f /media/cdrom

Note: installing libgtk1.2 is just to have a gui installer instead of console/ascii looking installer

it worked for me.
