linux如何開啟telnet服務？
工具/原料
Linux
xinetd-2.3.14-34.el6.x86_64.rpm
方法/步驟
1. 切換至root用戶；
2. 如果Linux沒有安裝telnet服務需要先安裝，安裝過開通即可；
3. 檢測telnet的rpm包是否安裝
[[email protected] ~]# rpm -qa telnet
telnet-0.17-48.el6.x86_64
[[email protected] ~]#
4. 安裝telnet安裝包：
[[email protected] ~]# rpm -ivh xinetd-2.3.14-34.el6.x86_64.rpm
warning: xinetd-2.3.14-34.el6.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID fd431d51: NOKEY

[[email protected] ~]#
5. 修改telnet服務配置文件
vi /etc/xinetd.d/telnet
service telnet
{
disable = yes
flags = REUSE
socket_type = stream
wait = no
user = root
server = /usr/sbin/in.telnetd
log_on_failure += USERID
}
將disable=yes改為disable=no
注意：安裝telnet-server服務後，系統才會有/usr/sbin/in.telnetd文件
6.重啟telnet服務
[[email protected] root]#service xinetd restart
7. 測試是否可以，若果不行，檢查防火牆是否關閉
[[email protected] ~]# telnet 127.0.0.1
