Using SSH over the HTTPS portSometimes, firewalls refuse to allow SSH connections entirely. If using HTTPS cloning with credential caching are not a option, you can attempt to clone using an SSH connection made Ove R the HTTPS port. Most firewall rules should allow this, but proxy servers may interfere.GitHub Enterprise Users:accessing GitHub Enterprise via

In linux, root users are prohibited from using ssh to log on and access control over ssh. in Linux, by default, root users can log on through ssh. However, for security reasons, this permission is inappropriate because hackers may crack your root password by brute force and then enter your system. oh, damn it ..... for security reasons, we usually operate on linu
The security of the server is self-evident, the first step in server security setting is to block the portal.
For Linux, blocking the entrance, is not allow others to casually into our servers inside the mess, otherwise an order "RM-RF/", the consequences of unimaginable. So we can't let people into our servers, and we can't let others use the root user. So the best thing to do is:
On Linux, set to prevent root remote logins, and modify the SSH port

Method One: Use Puttygen.exeThe first step: Creating a secret key
Run Puttygen.exe, select the key type and length you want, use the default SSH2 (RSA), and set the length to 1024.
Passphrase can be empty so that you don't have to enter a password at logon.
Click the Save private Key button to save the public key and private key, for example, Key.ppk,public key does not need to be saved, then the Puttygen.exe load feature can be used to display the common key.
Step Two: Upload the key

In this case do not think about how to re-modify the password, choose to re-create an SSH key, (PS: According to the investigation is git to ensure security does not have the option to re-modify the password).
