2. Open the vnc service port

VNC remote Control under SUSE Linux system

After SSH logs in, execute the vncserver command

Hint: You will require a password to access your desktops.

Set the password for remote access.

Password: (enter password)

Verify: (enter again)

Hint: Would you like to enter a view-only password (yzone)? N (whether to enter a password that can only be viewed, choose No)

The prompts are as follows:

Xauth: creating new authority file / root/.Xauthority

New'X' desktop is linux-eyh7:1 (Desktop number 1)

Creating default startup script / root/.vnc/xstartup

Starting applications specified in / root/.vnc/xstartup

Log file is / root/.vnc/linux-eyh7:1.log

Configure the xstartup startup script. Launch the gnome graphical interface window

Edit / root/.vnc/xstartup script with VI

The contents are as follows:

#! / bin/sh

Xrdb $HOME/.Xresources

Xsetroot-solid grey

Xterm-geometry 80x24+10+10-ls-title "$VNCDESKTOP Desktop" &

Twm &

Change the last line to

Startgnome

DISPLAY=:1 gnome-session

To launch the gnome graphical interface window.

After saving, restart vnc.

How to restart the vncserver service:

[root@testdb ~ # cd / tmp

[root@testdb ~ # rm. X2-lock (delete lock file)

[root@testdb ~ # cd / tmp/.X11-unix

[root@testdb ~ # rm * (delete vnc process)

[root@testdb ~] # vncserver: 1

Download the windows vnc client software.

Run the VNC viewer and enter the IP and desktop number of the server:

For example, 10.60.30.112purl

Then enter the VNC connection password to log in.

Control through the browser:

If the main console does not have vnc viewer installed, it can also be controlled through the browser. For example, if the access address is http://10.60.30.112:5801/ (where the port number = desktop display number + 5800, and the previous configuration prompt that the desktop number is 1, so the port number is 5801), a login interface will appear.

You need a browser to open java applet.

3There is Wireshark to grab the system package.

# wireshark (execute the wireshark pop-up graphical interface to select the network card you want to grab the package)

4 the skill of using Wireshark expression-- IP filtering

(1) Source IP: (take 192.168.0.105 as an example of source IP, see figure 1.1)

Expression: ip.src==192.168.0.105, or ip.srceq192.168.0.105

Meaning: filter out packets whose source IP is 192.168.0.105.

(2) Target IP: (for example, IP for the purpose of 119.147.74.18, see figure 1.2)

Expression: ip.dst==119.147.74.18, or ip.dsteq119.147.74.18

Meaning: filter out the packet whose destination IP is 119.147.74.18.

(3) filter directly by IP: (take 202.105.182.132 as an example IP, see figure 1.3)

Expression: ip.addr==202.105.182.132, or ip.addreq202.105.182.132

Meaning: filter out the packets related to 202.105.182.132
