1、Openssh升级操作步骤一、开启Telnet远程管理1.1修改/etc/xinetd.d/krb5-telnet文件#vi/etc/xinetd.d/krb5-telnetkrb5-telnet文件内容如下：#default:off#description:Thekerberizedtelnetserveracceptsnormaltelnetsessions,#butcanalsouseKerberos5authentication.servicetelnet{flags=REUSEsocket_type=streamwait=nouser=rootserver=/usr/

2、kerberos/sbin/telnetdlog_on_failure+=USERIDdisable=no//默认为yes，即启用禁用telnet服务按照红色字体进行修改，修改完毕保存文件退出。1.2开启xinetd服务#/etc/init.d/xinetdrestart[root@web2~]#/etc/init.d/xinetdrestart停止xinetd：[确定]启动xinetd：[确定]#netstat-tnlp

3、grep:23[root@web2~]#netstat-tnlp

4、grep:23tcp000.0.0.0:230.0.0.0:*LISTEN1433/xine

5、td注：在Web2服务器上执行/etc/init.d/xinetdrestart提示错误下载包xinetd-2.3.14-10.el5.i386安装即可#rpm–ivhxinetd-2.3.14-10.el5.i3861.3停止SSHD服务#/sbin/servicesshdstop[root@web2~]#/sbin/servicesshdstop停止sshd：[确定]cp/etc/init.d/sshd/root/备份复制启动脚本[root@web2~]#cp/etc/init.d/sshd/root/[root@web2~]#cd/root/[root@web2~]#lsa
