VNCSERVER,SSH Secure Shell client,window remote Control Linux

1.VNC remote connection to Linux graphical desktop

2.SSH Secure Shell Client connection to Linux terminal

3. Set FTP and Linux transfer files

1.VNC remote connection to Linux graphical desktop

Run under CentOS:

Yum-y instll VNC Vnc-server

After running, rpm-q Vncserver: Package Vncserver was not installed, do not know what reason, yum search vnc found there are several versions, choose to run

Yum Install Tigervnc-server

Yum Install Tigervnc

Below the command line, the Vncserver vncconfig vncpassword option appears

Start Vncserver (server side)

VNCSERVER:N: N is sessionnumber, does not specify a default of 1, the first prompt to enter a password,

You can change the password later with the Vncpassword command. VNC default port is 5900, Remote Desktop Connection port is 5900+n (specified by Vncserver command)

Close Vncserver:

Vncserver-kill:n

View Connections

Vncserver-list

Modifying a configuration file

Vim/etc/sysconfig/vncservers
# vncservers= "2:myusername"
# vncserverargs[2]= "-geometry 800x600-nolisten tcp-localhost"
vncservers= "1:root 2:kang"

vncserverargs[1]= "-geometry 1024x768"

The port number, which is used when connecting ports, geometry desktop size, and other basic parameters

Configuring firewalls

The VNC server listens on the port is starting from 5900, the display:1 listens for 5901 display:2 the listener is 5902, and so on

Vim/etc/sysconfig/iptables

-A input-m state--state new-m tcp-p TCP--dport 5901 ACCEPT

Restart Firewall: Service iptables restart

Boot start:

Chkconfig Vncserver on

To start the desktop configuration:

Vim/root/.vnc/xstartup Note Backup

#!/bin/sh
#Uncomment the following and lines for normal desktop:
unset Session_manager (Remove the previous comment number)
EXEC/ETC/X11/XINIT/XINITRC (Remove the previous comment number)
[-x/etc/vnc/xstartup] Exec/etc/vnc/xstartup
[-R $HOME/. Xresources] Xrdb $HOME/. Xresources
Xsetroot-solid Grey
Vncconfig-iconic &
Xterm-geometry 80x24+10+10-ls-title "$VNCDESKTOP Desktop" &
TWM &
Gnome-session & Set Starting GNOME Desktop (add this line to use the Gnome interface, otherwise the Xfce interface)

Primary service startup:

Service Vncserver Start (only the interface defined by/etc/sysconfig/vncservers is started)

Start multiple interfaces: (second interface for root login)

Vncserver:2 (to add configuration)

To install the client:

Yum-y Install Tigervnc

Vncviewer Start

SECURECRT is used as a terminal, faster.

The difference between VNC and Xmanager:

VNC is a remote connection to the operating system, all operations on the Linux side of the server, even if the network is interrupted, does not affect the operation, and Xmanager is the host server through the port

UI interface to the local computer for presentation, and if the network is interrupted during the operation, the operation fails

VNC Clipboard cannot cross local and remote, while Xmanager can vnc only hundreds of K,XM have dozens of m,xmanage only commercial version

2.SSH Secure Shell Client connection to Linux terminal

PUTTY.SECURECRT, I heard that SSH Secure Shell client is the putty+securecrt of the complex, trial the following, you can directly from the Windows and Linux directory directly transfer files, also provides and SECURECRT similar interface, very convenient, for the moment this is used, and not configured.

3. transferring files with Linux

On the Linux side:

Yum-y Install VSFTPD

Modify Configuration

Vim/etc/vsftpd/vsftpd.conf
Add some of the necessary configuration:

Local_enable = YES

Write_enable = YES Cancels the comments of the two lines

Start vsftpd:vsftpd Start

In this way, the FTP server is ready to log in to the virtual machine with CuteFTP, and the port defaults to 21.

Results find CuteFTP serial number found nearly 10, resolutely abandoned.
