Password-less SSH SCP

 

General execution:

 

Java code

Scp/home/daisy/full.tar.gz root@172.19.2.75:/home/root

 

After the command is executed, enter the root ssh password of server B 172.19.2.75. After the input, the file is copied.

 

Password-free ssh configuration is not required for distributing SCP in Linux

 

 

On serverA:

Java code

# Ssh-keygen-t rsa

# Ls/root/. ssh

Id_rsa id_rsa.pub known_hosts

# Chmod 755/root/. ssh

# Chmod 600/root/id_rsa

# Scp id_rsa.pub serverB:/root/. ssh/authorized_keys

 

# Scp aa.txt serverB:/root

 

 

No Password is required in the future. Scp aa.txt serverB:/root

 

 

When ssh-keygen-t rsa is pushed, press Enter.

 

 

On serverA, chmod 755/root/. ssh

On serverA, chmod 600/root/id_rsa

 

 

Ssh-copy-id

 

Method 2: ssh-copy-id

Method 3:

[Code = & quot; code & quot;] # ssh-keygen

# Cat ~ /. Ssh/id_rsa.pub | ssh user @ server & quot; cat-& gt ;~ /. Ssh/authorized_keys & quot;
