CentOS 5.5 에는 기본적으로 VNC Server가 설치되어 있어 환경설정과 서비스 등록만으로 VNC를 사용할 수 있다.

1. 환경

- CentOS 5.5 : 설치됨
- VNC Viewer : http://www.uvnc.com/download/ 에서 다운로드

2. 설정

# vi /etc/sysconfig/vncservers

3. vncservers 내용 수정

# The VNCSERVERS variable is a list of display:user pairs.

# Uncomment the lines below to start a VNC server on display :2

# as my 'myusername' (adjust this to your own). You will also

# need to set a VNC password; run 'man vncpasswd' to see how

# to do that.

# DO NOT RUN THIS SERVICE if your local area network is

# untrusted! For a secure way of using VNC, see

# <URL:http://www.uk.research.att.com/archive/vnc/sshvnc.html>.

# Use "-nolisten tcp" to prevent X connections to your VNC server via TCP.

# Use "-nohttpd" to prevent web-based VNC clients connecting.

# Use "-localhost" to prevent remote VNC clients connecting except when

# doing so through a secure tunnel. See the "-via" option in the

# `man vncviewer' manual page.

# VNCSERVERS="2:myusername"

# VNCSERVERARGS[2]="-geometry 800x600 -nolisten tcp -nohttpd -localhost"

VNCSERVERS="1:root"

VNCSERVERARGS[1]="-geometry 12800x800"

4. VNC 암호 설정

# vncpasswd
Password:
Verify:

5. Port 확인 및 방화벽 오픈

# netstat -antp
