CentOS下安装SecureCRT的sz/rz工具包（转）
CentOS下安装SecureCRT的sz/rz工具包
新安装的CentOS5.5系统，在secureCRT下使用rz sz 上传下载文件时出现如下提示：
[root@webslave2 etc]# sz hosts
-bash: sz: command not found
[root@webslave2 etc]#
由上述现象可知，很可能没有安装相应的软件包；sz rz 命令所需要的软件包是lrzsz
下面检查软件包是否安装？
[root@webslave2 etc]# yum list installed lrzsz
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
* addons: mirror.neu.edu.cn
* base: mirror.neu.edu.cn
* extras: mirror.neu.edu.cn
* updates: mirror.neu.edu.cn
Error: No matching Packages to list 由此可知没有安装此包
[root@webslave2 etc]#
下面安装lrzsz软件包，可通过yum安装，比较方便！
先查看下载源中的软件包
[root@webslave2 etc]# yum search lrzsz
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
* addons: mirror.neu.edu.cn
* base: mirror.neu.edu.cn
* extras: mirror.neu.edu.cn
* updates: mirror.neu.edu.cn

安装软件包（使用yum自动安装：）
[root@webslave2 etc]# yum -y install lrzsz
Loaded plugins: fastestmirror

* addons: mirror.neu.edu.cn
