Rename Linux hostname

azhari30 — Tue, 22 Apr 2008 05:50:25 +0000

Change the hostname on a running system

(http://www.ducea.com/2006/08/07/how-to-change-the-hostname-of-a-linux-system/)

On any Linux system you can change its hostname with the command ‘hostname‘ (surprised?)… Here are some quick usages of the command line hostname:

hostname

without any parameter it will output the current hostname of the system.

hostname --fqd

it will output the fully qualified domain name (or FQDN) of the system.

hostname NEW_NAME

will set the hostname of the system to NEW_NAME. This is active right away and will remain like that until the system will be rebooted (because at system boot it will set this from some particular file configurations – see bellow how to set this permanently). You will most probably need to exit the current shell in order to see the change in your shell prompt.

Open file /etc/sysconfig/network
change hostname with your preferred hostname
save the file and try to reboot to check if your hostname changed was sucessfull

Step-by-step enable remote desktop on linux using vnc

(http://www.linglom.com/2008/02/11/enable-remote-desktop-on-linux-using-vnc/)

In this section, I’ll show how to configure VNC server on Redhat server and using VNC Viewer connect the server remotely from Windows XP.

On Redhat server, login with your username that you want to enable remote access. In this example, I will use ‘admin’ user.
Open Terminal, type ‘vncpasswd’. Type your password and verify password again. This command will use to set you password for remote access for the current user.
Before next step, you need to logged on as root by type ’su root’.
Edit the file /etc/sysconfig/vncservers by type ‘ vi /etc/sysconfig/vncservers’.
Note: If you are new to Linux, vi is an editor tool in command line mode on Linux.
You’ll see text file as in the figure below. Next, I’ll edit on the highlight line.
Uncomment on the highlight line. If you have more than one usernames that want to enable remote acces, you can change VNCSERVERS value in this format, “1:username1 2:username2 3:username3 ….”. In this example, I have only one user which is root so this line of mine is ‘VNCSERVERS = “1:admin”‘.
Now save the file and exit. To save file, hold ESC + ‘:’ and type ‘wq’ to write and quit file.
Next, log off the user if you are not user ‘root’ and log in as root. Enable VNC service by type ‘chkconfig vncserver on’. Then, start the VNC service by type ’service vncserver start’.
If you have firewall enable on Redhat, be sure that your firewall configuration won’t block connection from remote computer by open port TCP 5901 for remote access. Open Applications -> System Settings -> Security Level. Add ‘5901:tcp’ on Other ports.
Note: VNC uses TCP protocol on port 5901.
Now you can connect Redhat server from remote computer. On my Windows XP computer, open VNC Viewer on Windows XP, type IP Address of Redhat server with number as a username specify in step 6. In this example, I want to remote to Redhat server as ‘admin’ user which I assign as number 1 in step 6 (1:admin) and my Redhat server is 10.110.141.220. So I type ‘10.110.141.220:1′.
Note: You can download VNC Viewer for free at realvnc.com
Type your password for ‘admin’ user which has been assign in step 2.
Now you have connect to Redhat server remotely. But you’ll see that the interface looks different. You have to do a little thing more.
On Redhat server, open terminal and type ‘vi /home/username/.vnc/xstartup’. In this example, I type ‘vi /home/admin/.vnc/xstartup’.
Note: If you going to enable remote access for user ‘root’, the file would be at ‘/root/.vnc/xstartup’.
Uncomment these two lines and save the file.
Note: If you want to force to load Gnome or KDE Desktop on remote access, edit the last line from ‘twm &’ to ’startx &’ for Gnome and ’startkde &’ for KDE Desktop.
Type ’service vncserver restart’ to apply changes.
Reconnect using VNC viewer on remote computer again. Now you will see the desktop as you were log in at the server but now you’re remotely .

Sharing Desktops Using VNC

Virtual Network Computing (VNC) consists of server and client software that enables

you to assume remote control of a full desktop display from one computer on another. In Fedora,

RHEL, and similar systems, you need the vnc package to access a remote desktop on

Chapter 13: Doing Remote System Administration

your display (client) and vnc-server to share a desktop from your computer (server).

To install those packages, type either (or both) of the following:

# yum install vnc

# yum install vnc-server

VNC clients and servers are available for, and interoperable with, many different operating

systems. VNC servers are available on Linux, Windows (32-bit), Mac OS X, and

Unix systems. VNC clients are offered on those, and many other types of systems

(including OS/2, PalmOS, and even as a Java application running in a web browser).

Setting Up the VNC Server

From your Linux desktop, we’ll assume you are using the default display (DISPLAY=:0)

as your local desktop. So we’ll set out to create independent displays accessible via

VNC. To start, open the vncservers file on the Linux system acting as your VNC

server (as root user) using any text editor:

# vi /etc/sysconfig/vncservers

In that file, create a display:user pair to identify a VNC desktop. These user accounts

must be valid user names for your system. Here are two different examples:

VNCSERVERS=”1:francois”

VNCSERVERS=”1:francois 2:chris”

Then as each user, run the vncpasswd command to create the password each of those

users will need to connect to their own desktops on the VNC server. In our example,

we run the following as the user francois:

$ vncpasswd

Password: *******

Verify: *******

Finally, you can start the VNC service (vncserver) as you would any other service in

Fedora and similar systems. Type the following as root user:

# chkconfig vncserver on

# service vncserver start

If you are using the iptables firewall built into your system, make sure you open the

port(s) for VNC. Each display runs on its own port. Display number N is accessed on

TCP port 5900+N. For example, display 1 is accessible on port 5901. Refer to Chapter 14

for more details on iptables.

Starting Up the VNC Client

With the VNC server running, you can connect to a desktop on that server from any

of the client systems mentioned earlier (Windows, Linux, Mac OSX, UNIX, and so

Chapter 13: Doing Remote System Administration

on). For example, assuming your VNC server is on a system named myserver, you

could type the following command to start that remote desktop from another Linux system:

$ vncviewer myserver:1 Connect as francois on display 1

$ vncviewer myserver:2 Connect as chris on display 2

You can also use tsclient to connect; for this example, you would just specify

myserver:1 as the computer and VNC as the protocol. By default, once you connect

via VNC, all you get is a very basic window manager (twm) and a terminal. To get the

full Fedora desktop next time the user logs in, you should edit your VNC xstartup file

on the VNC server. For example, log in as the user (in this example, francois or chris)

and type the following:

$ vi ~/.vnc/xstartup

When editing that file, remove the comment characters from two lines so they appear

as follows:

unset SESSION_MANAGER

exec /etc/X11/xinit/xinitrc

On older versions of the VNC software, the file may not exist. So create it and add the

two lines above. After creating the file, set its permissions as follows:

# chmod 755 ~/.vnc/xstartup

Then, for the changes to take effect, you need to restart the VNC server. As root

user, type:

# service vncserver restart

You must accept the Office End User License Agreement every time that you start an Office program

azhari30 — Thu, 17 Apr 2008 02:27:13 +0000

RESOLUTION

To resolve this behavior, follow these steps:

1.	Log on to the computer by using a user account that has administrative credentials.
2.	Start an Office program, such as Word. The End User License Agreement dialog box appears.Note For Windows Vista, click Start, click All Programs, click Microsoft Office, right-click an Office program, click Run as administrator, and then click Continue.
3.	Click I Accept.
4.	Exit the Office program that you just started.
5.	Repeat step 2 to step 4 for the other Office programs that still prompt you with the EULA.

To work around this behavior, follow these steps:

Log on to the computer by using an Administrator user account.

If you are using Microsoft Windows XP, click Start, click Run, type regedit, and then click OK. If you are using Microsoft Windows 2000 Server, type regedt32.Note In Windows Vista, you may receive a User Account Control (UAC) dialog box. You must click Continue to open Registry Editor.

Locate and then right-click the following registry subkey as appropriate.

•	For the 2007 Microsoft Office suites: HKEY_LOCAL_MACHINE\Software\Microsoft\Office\12.0
•	For Microsoft Office 2003: HKEY_LOCAL_MACHINE\Software\Microsoft\Office\11.0
•	For Microsoft Office 2002: HKEY_LOCAL_MACHINE\Software\Microsoft\Office\10.0
•	For Microsoft Office 2000: HKEY_LOCAL_MACHINE\Software\Microsoft\Office\9.0

Click Permissions.

Click Users (Computer_name\Users), and then click to select the Allow check box for the Full Control permission.

Click OK, and then quit Registry Editor.

Start an Office program, and then accept the End User License Agreement.

Repeat steps 2 through 4, and then remove the Full Control permission that you gave to Users (Computer_name\Users) in step 5. To do this, locate Users (Computer_name\Users), and then click to clear the Allow check box for the Full Control permission.

Click OK, and then exit Registry Editor.
