Linux modified ssh port 22

vi /etc/ssh/ssh_config

vi /etc/ssh/sshd_config

Change it to port 8888.

service sshd restart (redhat as3) as root

Use Putty, port 8888

The default SSH port under Linux is 22. For security reasons, the SSH port is now modified to 1433. The modification method is as follows:

/usr/sbin/sshd -p 1433

To enhance security

First add a user with normal permissions:

#useradd uploader

#passwd uploader

//Set password

Production machines prohibit ROOT remote SSH login:

#vi /etc/ssh/sshd_config

put

PermitRootLogin yes

changed to

PermitRootLogin no

Restart sshd service

#service sshd restart

Remote administration log in as normal user uploader, and then switch to root user with su root to get the highest privileges
