1.Ubuntu安装telnet

安装openbsd-inetd
sudo apt-get install openbsd-inetd

安装telnetd
sudo apt-get install telnetd

重启openbsd-inetd
sudo /etc/init.d/openbsd-inetd restart

查看telnet运行状态
sudo netstat -a | grep telnet

登录
telnet IP address

访问:

hongdada@ubuntu:~$ telnet 192.168.1.203 22
Trying 192.168.1.203...
telnet: Unable to connect to remote host: Connection refused

使用 netstat -napt查看端口是否被监听

hongdada@ubuntu:~$ netstat -napt
(并非所有进程都能被检测到,所有非本用户的进程信息将不会显示,如果想看到所有信息,则必须切换到 root 用户)
激活Internet连接 (服务器和已建立连接的)

Ubuntu 默认安装了client端,但是没有安装Server端,所以现在要安装openssh-server

sudo apt-get install openssh-server

安装以后查看22端口是否被监听

netstat -antp|grep 22

如果只有ssh-agent那ssh-server还没有启动,需要/etc/init.d/ssh start或者service ssh start,如果看到sshd那说明ssh-server已经启动了。

ssh-server配置文件位于/ etc/ssh/sshd_config,在这里可以定义SSH的服务端口,默认端口是22,你可以自己定义成其他端口号,如222。然后重启SSH服务:

sudo /etc/init.d/ssh restart

 

现在使用xshell访问Ubuntu
