1.首先应保证inetd守护进程是开启的，可输入#lssrc –s inetd查看

    [root@HAN04UX] /home/root #lssrc -s inetd
    Subsystem Group PID Status
    inetd tcpip 184490 active

active 表示inetd进程已开启

2.启动telnet服务： #startsrc -t telnet

    [root@HAN04UX] /home/root #startsrc -t telnet
    0513-124 The telnet subserver has been started.

3.停止telnet服务： #stopsrc -t telnet

    [root@HAN04UX] /home/root #stopsrc -t telnet
    0513-127 The telnet subserver was stopped successfully.

4.查看Telnet服务状态，#lssrc -t telnet

    [root@HAN04UX] /home/root #lssrc -t telnet
    Service Command Description Status
    telnet /usr/sbin/telnetd telnetd -a active

5.查看/etc/inetd.conf文件的以下字段是否被注释掉，如果被注释掉，说明开机时不自动打开Telnet服务

    [root@HAN04UX] /home/root #more /etc/inetd.conf
    ## @(#)62 1.17.1.14 src/tcpip/etc/inetd.conf, tcpinet, tcpip610 11/2/99 09:16:20
    ## IBM_PROLOG_BEGIN_TAG
    ......
    ftp stream tcp6 nowait root /usr/sbin/ftpd ftpd
    telnet stream tcp6 nowait root /usr/sbin/telnetd telnetd -a
    shell stream tcp6 nowait root /usr/sbin/rshd rshd
    ......
