Install the telnet service and enable

Because the existing OpenSSH needs to be uninstalled during the OpenSSH upgrade process, in order to keep the server's remote connection available, you need to

To enable the telnet service instead, if there is a problem with the upgrade, you can also log in to the server through telnet for fallback.

Also install the telnet daemon: xinetd

Install the telnet service

[root@test ~] # yum install telnet-* xinetd ­y

[root@test ~] #

[root@test ~] # rpm-qa | grep telnet

Telnet-0.17-64.el7.x86_64

Telnet-server-0.17-64.el7.x86_64

[root@test ~] #

[root@test ~] # rpm-qa | grep xinetd

Xinetd-2.3.15-13.el7.x86_64

[root@test ~] #

[root@test ~] #

Add xinetd service to boot self-startup

[root@test ~] # systemctl enable xinetd.service

Add telnet service to boot self-startup

[root@test ~] # systemctl enable telnet.socket

Created symlink from / etc/systemd/system/sockets.target.wants/telnet.socket to / usr/lib/systemd/system/telnet.socket.

[root@test ~] #

Restart the service:

Since the telnet service is also guarded by xinetd, after installing telnet-server, to start the telnet service, you must restart xinetd

[root@test ~] # systemctl restart telnet.socket

[root@test ~] #

[root@test ~] # systemctl restart xinetd

[root@test ~] #

[root@test ~] #

Configure telnet root user access

Method 1:

Linux by default, root users cannot log in using telnet. You need to modify the end of / etc/secrueety file to add pts/1, pts/2, pts/3 or rename the secrueety file.

[root@test ~] # cat / etc/securetty

# permissive-SELinux prints warnings instead of enforcing.

# disabled-No SELinux policy is loaded.

# SELINUX=enforcing

# SELINUXTYPE= can take one of three two values:

Restore a shared library

Because OpenSSL_1.0.2k does not provide libcrypto.so.10 and libssl.so.10 libraries, and yum, wget and other tools rely on this library, you need to restore these two libraries that were previously backed up, and other libraries can be restored depending on the situation.
