前几天新安装的服务器，今天需要用mget *下载文件的时候出错：

查看内核[root@tonykorn97 ~]# uname -aLinux tonykorn97 2.6.18-53.el5 #1 SMP Wed Oct 10 16:34:19 EDT 2007 x86_64 x86_64 x86_64 GNU/Linux[root@tonykorn97 ~]#

当时还以为是安装的时候没有把32位兼容程序安装上，重新安装了一次，安装后一样。

此时查看ftp命令在那个目录下面：

[root@tonykorn97 ~]# which ftp/usr/kerberos/bin/ftp[root@tonykorn97 ~]# ls -al /usr/kerberos/bin/ftp -rwxr-xr-x 1 root root 109472 Sep 12 2007 /usr/kerberos/bin/ftp

查看是那个安装包的文件

[root@tonykorn97 ~]# rpm -qf /usr/kerberos/bin/ftpkrb5-workstation-1.6.1-17.el5

移除这个文件

[root@tonykorn97 ~]# mv /usr/kerberos/bin/ftp /usr/kerberos/bin/ftp.bak

重新查看一下还有没有ftp客户端

[root@tonykorn97 ~]# which ftp/usr/bin/ftp[root@tonykorn97 ~]#

用这个ftp下载文件正常，查看路径可以知道/usr/kerberos/bin目录在/usr/bin目录前面，先执行/usr/kerberos/bin目录下面的文件。

[root@tonykorn97 installfiles]# env | grep PATH

PATH=/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin[root@tonykorn97 installfiles]#

这个方法只是暂时满足工作需求，至于为什么为出现上面的错误还没有研究。
