Ubuntu 9.10 - JDK6

Ubuntu 9.10 supports openjdk by default. To install the SUN JDK, the /etc/apt/sources.list file has to be extended by the following lines:

• deb http://ftp.debian.org/debian squeeze main contrib non-free
• deb-src http://ftp.debian.org/debian squeeze main contrib non-free

After that, JDK install is simple:

1. sudo apt-get update
2. sudo apt-get install sun-java6-jdk
   

trac install - win XP

Components:

• Apache 2.0.63
  
• SVN server 1.5.5
  
• Python 2.5
• svn-python 1.5.5
  
• Genshi 0.5.1
• SetupTools 0.6c9
  
• Trac 0.11
• mod_python 3.3.1
  

How to install and configure:

1. Had to move IIS to port 1080 to make port 80 available for Apache:
   My computer /manage / IIS / default site / properties
   
2. Apache: next-next-OK
3. SVN server: extract the ZIP file and use the README in the zip file
   The referenced tortoisesvn howto is useless, but the end of the README itself is OK
   no installer, copy modules to Apache, add svnserver\bin to SYSTEM path, edit httpd.conf and REBOOT.
4. Run "svnadmin create d:\repository\subversion\sandbox"
   
5. Subversion is available now at http://localhost/svn
6. Python: next-next-OK
   
7. svn-python: next-next-OK
   
8. Genshi: next-next-OK
9. SetupTools: next-next-OK
10. Trac: next-next-OK
11. Run python25\Scripts\trac-admin.exe
    trac-admin d:\repository\trac\sandbox initenv
    (SVN repository: d:\repository\subversion\sandbox)
    
12. test: python25\Scripts\tracd --port 8000 d:\repository\trac\sandbox
    URL: http://localhost:8000/sandbox
13. mod_python: next-next-OK
14. Apache config:
    
    copy mod_dav_svn.so & mod_authz_svn.so to apache2\modules
    
    enable (uncomment in apache2\conf\httpd.conf):
    LoadModule dav_module modules/mod_dav.so
    LoadModule dav_fs_module modules/mod_dav_fs.so
    
    add:
    LoadModule dav_svn_module modules/mod_dav_svn.so
    LoadModule authz_svn_module modules/mod_authz_svn.so
    LoadModule python_module modules/mod_python.so
    
    add locations and authentication to httpd.conf, see http://trac.edgewall.org/wiki/TracModPython
    
    Note: I had to use apache2/bin/htpasswd.exe with the "-p" option to generate authentication that works.
    
    
15. Enable WebAdmin for your username:
    python25\scripts\trac-admin.exe /repository/trac/sandbox permission add username TRAC_ADMIN
    
    
16. Test: http://localhost/trac/sandbox
    (works fine for me)

How to suck:

• I have lost a lot of time trying to integrate svn-win32-1.5.5_py.zip to python.
  The solution was installing svn-python-1.5.5.win32-py2.5.exe
  

NSLU2

My NSLU2 came with the ancient firmware version v2.3R24. The newest available firmware is V2.3R63, although dead links can be found at the linksys site to V2.3R76.

I have tried to upgrade using the web interface, but it did not work, just the status led started blinking green/amber for hours, until switch-off (in theory, the upgrade should have been finished in 5-10 minutes). After restart the unit came up with the old firmware.

Subversion

Windows szerverek:

• http://www.collab.net/downloads/subversion/
• Regisztráció szükséges a letöltéshez
• A web site a technikai jellemzők bemutatása helyett a költségmegtakarítással ködösít
  


• http://www.visualsvn.com/server/download/
  
• Azonnal letölthető, minden benne van
• A web site szerint a jogosultságok kényelmesen menedzselhetők
• Ezt választottam.
• A szerver beállítása és egy repository (adf) létrehozása egyszerű volt.
• A TortoiseSVN-ben a https://localhost:8443/svn/adf címet kellett beállítani az eléréséhez. (Ezért egy kicsit küzdeni kellett, magamtól nem így próbálkoztam).
• Utálja, ha a víruskergető nézegeti a repository tartalmát (commit közben leáll, ha más process is megnyitja a fájlt).
  
• Az Oracle is ezt ajánlja: http://www.oracle.com/technology/pub/articles/adf-development-essentials/part1.html
• http://subversion.tigris.org/servlets/ProjectDocumentList?folderID=91
• A trac telepítéséhez, a helyi Python kapcsolathoz ezt használom.
  
• Apache2 is kell hozzá, egy kicsit dolgozni kell vele.

Linux on Acer TravelMate 4062

• Ubuntu 6.0.6 - nice, but does not use the 1280x800 screen resolution and wireless does not work

• OpenSuse 10.1 - configured the display correctly to 1280x800, wireless is OK, but the wired ethernet does not work. Second install: wired ethernet is OK. The NetworkManager applet could not connect to wireless, but disconnected the wired.
  

• Fedora Core 5 - Desktop/System Settings/Display knows the 1280x800 resolution, but the Desktop/Preferences/Screen Resolution does not. Wireless is not detected.
