specify which branch you want to merge with.See git-pull(1) for details. git pull Run the local remote branch association command: Git Branch -- Set-Upstream-To = origin/remote_branch your_branch Here, origin/remote_branch is the remote branch corresponding to your local branch; your_branch is your current local branch. ( $ Git branch: local branch $ Git branch-VV (two V), you can see the remote branch of the local branch tracking. ) Then execute remote submission: $ Git push origin master

In linux, ssh logon to Permanently added (RSA) to the list of known hosts solves the following problems: 1 [root @ www] # ssh admin@xxx.xxx.xxx.xxx2The authenticity of host 'xxx. xxx. xxx. xxx can't be established.3RSA key fingerprint is f4: d0: 1a: 9c: 09: 65: 78: 71: 25: 3

a pair of keys (private key + public key) to place the public key on the server registration. When a user logs on to a server from a client, the server receives a security authentication request using the key (that is, the public key registered on the server), the server is first compared to the public key that is sent from the client and the public key registered with the client, and if it is consistent, the server uses that public key to encrypt data to "challenge"[ 1], thus avoiding man-in-t

/identity. pub The user's default RSA1 authentication Public Key (SSH-1 ). This file does not need to be kept confidential. The content of this file should be added to the ~ Of All RSA1 target hosts ~ /. Ssh/authorized_keys file. ~ /. Ssh/id_dsa The user's default DSA Identity Authentication private key (

security of PKI can be based on the problem of "large number decomposition and primality detection". The multiplication of two large primes is easy to be achieved on the computation, and the calculation of the multiplicative integral solution is quite large. The known public key solves the private key, which is equivalent to finding the factor of n without knowing the two factors p and q, it is very difficult but its computation speed is very slow, s

How to avoid password-free mutual trust between ssh-Principle: Private Key Encryption and Public Key decryption Establish an SSH trust relationship between experiment web1 (192.168.204.7) and web2 (192.168.204.9) The command ssh-keygen is used to generate the public key and private key.
