尽管Linux下已经自带了telnet.不过telnet相对来说不是很安全,于是PUTTY横空出世了.PUTTY是一款自由的telnet/SSH 客户端,而且是开放源码的.你可以去它的官网看看:http://www.putty.nl/ 呵呵,看了一下好像只有WINDOWS和UNIX的二进制包和源码包,好像没有LINUX下的源码包.不过LINUX是类UNIX的操作系统,用UNIX 下的源码包在LINUX下编译应该是能够编译通过的.
     好了,在下面这个网址下载UNIX下的源码包putty-0.59.tar.gz.
     http://www.putty.ws    

好了,现在开始解压源码包:
[root@SunLife Desktop]# ls

[root@SunLife Desktop]# mkdir /home/zhc/putty
[root@SunLife Desktop]# mkdir /home/zhc/putty/source
[root@SunLife Desktop]# mv putty-0.59.tar.gz /home/zhc/putty/source/
[root@SunLife Desktop]# cd /home/zhc/putty/
[root@SunLife putty]# ls
source
[root@SunLife putty]# tar -zxvf source/putty-0.59.tar.gz

     OK,编译完毕,上面是编译生成的目标文件.现在可以试试了.

 呵呵,怎么样,还不错吧.你可能不想每次都这样启动PUTTY吧.那我们就为它添加一个符号链接吧:
[root@SunLife /]# cd /usr/local/bin/
[root@SunLife bin]# ln -s /home/zhc/putty/putty-0.59/unix/putty ./putty
[root@SunLife bin]# ls
arm-elf-addr2line arm-elf-c++filt arm-elf-gcc      arm-elf-objcopy   arm-elf-readelf arm-elf-unprotoize mencoder
arm-elf-ar         arm-elf-elf2flt arm-elf-ld       arm-elf-objdump   arm-elf-size     elf2flt             mplayer
arm-elf-as         arm-elf-flthdr   arm-elf-ld.real arm-elf-protoize arm-elf-strings flthdr              putty
arm-elf-c++        arm-elf-g++      arm-elf-nm       arm-elf-ranlib    arm-elf-strip    genromfs            qvfb
[root@SunLife bin]# putty
[root@SunLife bin]# cd /
        呵呵,你现在就可以在任何目录下输入putty就可以启动PUTTY了.
[root@SunLife /]# putty
       如果你还不满意,你可以在你的桌面为它添加快捷方式.方法如下:
       用鼠标右击桌面,在弹出的菜单里选"创建启动器",然后把弹出的对话框填完,确定即可.
