1.编辑krb5-telnet和gssftp两个文件，将disable = yes，改为disable = no，然后重新启动xinetd  
\[root@node2 xinetd.d\]\# ls  
chargen-dgram   cvs            daytime-stream  discard-stream  echo-stream  ekrb5-telnet  klogin       kshell  rmcp   tcpmux-server  time-dgram  
chargen-stream  daytime-dgram  discard-dgram   echo-dgram      eklogin      gssftp        krb5-telnet  ktalk   rsync  tftp           time-stream  
  
\[root@node2 xinetd.d\]\# vi ekrb5-telnet  
\# default: off  
\# description: The kerberized telnet server accepts only telnet sessions, \\  
\#              which use Kerberos 5 authentication and encryption.  
service telnet  
\{  
        flags           = REUSE  
        socket\_type     = stream  
        wait            = no  
        user            = root  
        server          = /usr/kerberos/sbin/telnetd  
        server\_args     = -e  
        log\_on\_failure  += USERID  
        disable         = no  
\}  
  
\[root@node2 xinetd.d\]\# vi gssftp   
\# default: off  
\# description: The kerberized FTP server accepts FTP connections \\  
\#              that can be authenticated with Kerberos 5.  
service ftp  
\{  
        flags           = REUSE  
        socket\_type     = stream  
        wait            = no  
        user            = root  
        server          = /usr/kerberos/sbin/ftpd  
        server\_args     = -l -a  
        log\_on\_failure  += USERID  
        disable         = no  
\}  
  
\# service xinetd restart   
Stopping xinetd: \[  OK  \]   
Starting xinetd: \[  OK  \]  
  
2.ftp登录报错

修改/etc/xinetd.d/gssftp文件，将server\_args后面的-a删掉，然后重新启动xinetd服务。
