me and my stuff

Since gusty, compiz-fusion will start by default. I love eye candy but for resource shortage reason on my old box, sometime i need to switch to metacity. with alt-f2 and run 'metacity replace' is just work but not convenion. Thank for Tom that point me . Fusion-icon is use to switch between compiz and metacity window manager. For hardy, fusion-icon is in repos. installation is easy like pnix@pnix-a7n:~$ sudo aptitude install fusion-icon Reading package lists... Done Building dependency tree Reading state information... Done Reading extended state information Initializing package states... Done Building tag database... Done The following NEW packages will be installed: fusion-icon 0 packages upgraded, 1 newly installed, 0 to remove and 0 not upgraded. Need to get 29.8kB of archives. After unpacking 270kB will be used. ... Building tag database... Done pnix@pnix-a7n:~$ Running : alt-F2 and type 'fusion-icon -n' or if you want this everytime...

I just finish build the new hardy box at my office. then I go to open the file '/etc/network/interfaces' to add internal ip address and forget something. When I try to open it again, I got this. pnix@hardy-dev:~$ sudo nano /etc/network/interfaces sudo: timestamp too far in the future: Apr 29 01:41:32 2008 pnix@hardy-dev:~$ date Mon Apr 28 18:48:21 ICT 2008 pnix@hardy-dev:~$ I'm not sure why this happen may be some parts of the system using UTC, other parts using timezone-adjusted time. To fix this try code below to clear timestamp. pnix@hardy-dev:~$ sudo -k pnix@hardy-dev:~$ sudo nano /etc/network/interfaces [sudo] password for pnix:

Ubuntu 8.04 LTS code name Hardy Heron just released yesterday. Until now the server still busy, network upgrade[for me] need about 9xx MB download and will take about 1 days and something to do that[on 1mb ADSL from Thailand can you believe? :P]. So I try go for alternative CD . This is pretty much help, download time[for CD] reduce to 2 hours for 700MB. After burning, pop it into CD Drive, it will ask about "Do I want latest pakage from internet?". "Yes" will need more 300MB to download. Anyway it'not a day, estimate time are about 2-3 hours for upgrading. Hope that tomorow I will see hardy desktop on my box.

Last time , configure r4fxo on trixbox using genzaptelconf command will generate zapata-channels like this. ;;; line="4 FXO/1/3 FXSKS (In use)" signalling=fxs_ks callerid=asreceived group=0 context= from-pstn channel => 4 context=default This look ok except context is set to 'from-pstn', I can make outbound and inbound call with out any problem except the call will never hang up!!!. To fix this problem[from this post ], change 'context=from-pstn'[bold above] to 'context=from-zaptel'.

There are two ways to create a new database on existing oracle db server. One is using 'CREATE DATABASE' sql statement[this is too long,hard for me]. Another is using DBCA(Database Confguration Assistance), GUI Base Program. This way is more easy and I choose this way:). One note here is DBCA need X to run and I want to remote login to db server and run dbca from ssh, so ssh need '-X' for X11 forward[assume that DISPLAY variable on server is set, if not try 'export DISPLAY=localhost:0.0' on the server]. [poj@fedev ~]$ ssh -X -l oracle 192.168.1.59 oracle@192.168.1.59's password: Last login: Wed Apr 16 15:11:14 2008 from 192.168.1.122 /usr/X11R6/bin/xauth: creating new authority file /home/oracle/.Xauthority [oracle@k8n ~]$ cd /u01/app/oracle/product/10.1.0/db_1/bin [oracle@k8n bin]$ dbca

One of database box hang today. It doesn't let me ssh to see what happen, so I just shut it down and try to reboot again. But during boot process, I got "Kernel panic: VFS: Unable to mount root fs on...". err.. look like the disk is gone. Anyway, after few time of cold boot it give me a chance to backup my data:). I don't need all data in database[too many outdate data], so I decide to move some importance table to another database. Oracle has exp and imp utility to do this job. To export table test123 to file test123.dmp type follwing command. [oracle@Oracle-1 oracle]$ exp username/password TABLES=test123 FILE=test123.dmp Export: Release 8.1.7.0.1 - Production on Mon Apr 7 13:22:01 2008 (c) Copyright 2000 Oracle Corporation.
