SCP is similar to the CP or copy command, but it’s done via a secure network.
Here’s a CP command.
cp /dir1/filename /dir2 |
cp /dir1/filename /dir2
You can use SCP to copy file to another system. It requires login.
scp /dir1/filename user@server:/home/user |
scp /dir1/filename user@server:/home/user
This is using SCP to copy a file from 2 remote systems.
scp user@host1:/home/user/dir1/file.txt user@host2:/home/user/dir2 |
scp user@host1:/home/user/dir1/file.txt user@host2:/home/user/dir2
If WordPress is asking for FTP details when you’re trying to update a theme, plugin, or WordPress itself, you will need to edit your wp-config.php file to add the following line to your configuration.
define('FS_METHOD','direct'); |
define('FS_METHOD','direct');
Save the file and try updating again. It shouldn’t ask you for FTP details.
Passive FTP is a FTP mode that alleviates the issues with client firewalls. The client initiates a call to the server. The return traffic is allowed as long as the client has initiated it. In addition, the server sends a port command along with an ephemeral port that the client can connect to. The client initiates a call on that ephemeral port, and the connection is then established.
Egress port 21 and ephemeral ports 1024-65535 needs to be opened from the client side.
# From the client side, egress port 21 must be open. tcp:21 # From the client side, ephemeral ports from port 1024 to 165535 must be open. tcp:1024-165535 |
# From the client side, egress port 21 must be open. tcp:21 # From the client side, ephemeral ports from port 1024 to 165535 must be open. tcp:1024-165535
