ftp下載的時候用mget命令出錯

前幾天新安裝的伺服器，今天需要用mget *下載檔案的時候出錯：

檢視核心
[root@tonykorn97 ~]# uname -a
Linux 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 ~]#

當時還以為是安裝的時候沒有把32位相容程式安裝上，重新安裝了一次，安裝後一樣。

此時檢視ftp命令在那個目錄下面：
[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

檢視是那個安裝包的檔案
[root@tonykorn97 ~]# rpm -qf /usr/kerberos/bin/ftp
krb5-workstation-1.6.1-17.el5

移除這個檔案
[root@tonykorn97 ~]# mv /usr/kerberos/bin/ftp /usr/kerberos/bin/ftp.bak

重新檢視一下還有沒有ftp客戶端
[root@tonykorn97 ~]# which ftp
/usr/bin/ftp
[root@tonykorn97 ~]#

用這個ftp下載檔案正常，檢視路徑可以知道/usr/kerberos/bin目錄在/usr/bin目錄前面，先執行/usr/kerberos/bin目錄下面的檔案。

[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]#

這個方法只是暫時滿足工作需求，至於為什麼為出現上面的錯誤還沒有研究。
