SSH service and peanut shell domain name analysis

First, the installation instructions for the CentOS 5 example

1, install the necessary development kits

 [[email protected] ~]# yum install gcc gcc-c++ autoconf automake

2. Download phddns-2.0.2.16556.tar.gz to a directory

 [[email protected] ~]# wget http://download.oray.com/peanuthull/phddns-2.0.2.16556.tar.gz

3. Unzip all Files

 [[email protected] ~]# tar zxvf phddns-2.0.2.16556.tar.gz

4. Enter the directory and compile

[[Email protected]~]#CD Phddns-2.0.2.16556[[Email protected] Phddns-2.0.2.16556]#Aclocal[[Email protected] Phddns-2.0.2.16556]#Autoconf[[Email protected] Phddns-2.0.2.16556]#Automake[[Email protected] Phddns-2.0.2.16556]# ./Configure[[Email protected] Phddns-2.0.2.16556]# Make[[email protected] phddns< Span class= "pun" >-2.0. 2.16556]# CD Src[[email protected] Src]# ls -l phddns-< Span class= "PLN" >rwxr-xr-x 1 root root 80968 aug< Span class= "PLN" > 2 11: 18 Phddns              

5, the implementation of the compiled program and configuration (by default, using/etc/phlinux.conf, if the file does not exist automatically into the interactive configuration)

[[Email protected] src]# ./Phddns#输入服务器地址, you can use the default if there is no special caseEnterServer address(Press ENTERUsePhlinux3.Oray.Net):#输入您的Oray帐号名称EnterYourOrayAccount:#对应的Oray帐号密码Password:#选择帮定的网卡, if no special, the default can beNetwork Interface(S):Eth0:192.168.141.18Lo:127.0.0.1ChooseOne(DefaultEth0):#选择日志保存到哪个文件LogToUse(Default /Var/Log/Phddns.Log):#保存配置文件, select Yes to save directly to/etc/phlinux.conf, enter other to specify the fileSaveTo configuration file(/etc/Phlinux.Conf)?

Netonstatuschanged Okdomainsregisteredusertype : 0           

See above to indicate successful login, this time can press CTRL + C to exit the program first

6. Copy the Phddns to your desired location

[[email protected] src]# cp phddns /usr/bin/

7. Start the peanut shell in background mode and check the operation condition.

[[Email protected]~]# /Usr/Bin/Phddns-C/etc/Phlinux.Conf-Dphlinux startedAsDaemon![[Email protected]~]#Tail/Var/Log/Phddns.Log2011/08/02 11:28:58.256| ExecuteupdateOk, Beginkeepalive!2011/08/02 11:29:59.354| Sendkeepalive() 82082011/08/02 11:30:00.355| Recvkeepaliveresponse() DataComes,OPCODE:82722011/08/02 11:30:00.356| KeepaliveResponse received,Client IP: 116.231.123.962011/08/02 11:31:00.447| Sendkeepalive() 82082011/08/02 11:31:01.450|  recvkeepaliveresponse ()   Data Comes, Opcode: 82722011/08/ 02 11:31 :01.450| keepalive response Received, client ip< Span class= "pun" >: 116.231. 123.96                 

8. Exit the peanut shell

查看进程ID[[email protected] ~]# ps -A | grep phddns13731 ? 00:00:00 phlinux让后台进程退出[[email protected] ~]# kill -9 13731

9, the peanut shell added to the system when the start of operation

[[email protected] ~]# vi /etc/rc.local

Add a line to the end of the file:/usr/bin/phddns-c/etc/phlinux.conf-d

Second, SSH

SSH sub-client openssh-client and Openssh-server if you just want to login to another machine SSH only need to install Openssh-client (Ubuntu has default installation, if not then sudo apt-get install Openssh-client), if you want to make the native SSH service open, you need to install Openssh-server

 sudo apt-get install openssh-server

Then confirm that the Sshserver is started:

 ps -e |grep ssh

If you see sshd that means Ssh-server has been activated. If not, you can start this way:

 sudo /etc/init.d/ssh start

Ssh-server configuration file is located in/Etc/ssh/sshd_config, where you can define the SSH service port, the default port is 22, you can define yourself as a different port number, such as 222.

Then restart the SSH service:

 sudo /etc/init.d/ssh stop 或sudo service ssh stop sudo /etc/init.d/ssh start 或sudo service ssh start

Then use the following method to log in to SSH:

 ssh [email protected].168.1.112 username为192.168.1.112 机器上的用户，需要输入密码。

Disconnect: Exit
