Setup Samba Server on Ubuntu (Feisty Fawn)

1.install samba
sudo apt-get install samba

2.stop samba service, so that we can do configuration
sudo /etc/init.d/samba stop

3.configure samba
sudo gedit /etc/samba/smb.conf

4.setup share folder in smb.conf
add this at the end of smsb.conf
[SHARE]
path = /var/lib/share ;share directory
browseable = yes ;browseable
read only = no ;readonly
create mask = 0644 ;file creation mask
directory mask = 0755 ;directory creation mask

5. login setting
Default setting use linux user account to login, root is forbidden
in smb.conf
security = user
invalid users = root
you can share without login by setting
sercurity = share

6.start samba service
sudo /etc/init.d/samba start

6.create samba account
sudo smbpasswd -a [linuxUsername]

If you just want to share file between your linux and windows machine in your home like me.

Here is my handy setting :
security = share

[share]
path = [share folder path]
read only = no
writable = yes
browseable = yes
guest ok = yes

and then change that folder setting :
owner = nobody
folder = create and delete
file = read and write
group = nogroup
folder = create and delete
file = read and write

Install JDK on Linux (CentOS)

1. download the .bin runnable file from sun.
2. use chmod and change the .bin to executable mode.
3. run it. example: ./jdk1.6.0_06.bin

and then it will install itself.

But CentOS use redhat jdk under /usr/bin/java
you can check it with this command: which java
To change this environment setting for bash shell, add this to your [userhome]/.bashrc

export PATH=/[javahome]/bin:$PATH
export JAVA_HOME=”/[javahome]”

if you install your jdk to /root/jdk1.6.0_06, the result will be
export PATH=/root/jdk1.6.0_06/bin:$PATH
export JAVA_HOME=”/root/jdk1.6.0_06″

beware the difference between linux and windows (since I am windows user).
windows use “;”, linux use “:”
