The implementation method of installing telnet Service under CentOS7

Today, I upgraded openssl and openssh under Centos 7 and installed telnet by the way.

# install telnet to avoid ssh being unable to log in

Yum-y install xinetd telnet telnet-server

# allow root account to log in

Vi / etc/securetty

# add two lines at the end

Pts/0 pts/1

# add Firewall Port

Vi / etc/sysconfig/iptables-An INPUT-p tcp-m state-- state NEW-m tcp-- dport 23-j ACCEPT

# restart the service and shut down firewalld

Systemctl restart iptables systemctl disable firewalld systemctl stop firewalld

# Registration Service

Systemctl enable telnet.socket systemctl start telnet.socket systemctl enable xinetd systemctl start xinetd

The / etc/xinetd.d/telnet file was not generated by installing telnet under # centos7. I wrote one according to the previous configuration, which seems to be useless, and I didn't find any more information on the Internet.

# now this is enough for temporary use
