Note: For directions to switch the default ssh port at the faraway machine learn this phase.

Downloading Files Using SCP on a Different Port

To specify a distinct port than 22 when the usage of the SCP command, you want to put in force the -P flag as proven within the instance underneath, wherein the default port used to be modified to port 3940.

The syntax is beautiful easy as proven underneath.

scp -P Port> User>@IP/Host>:File> DestinationDirectory>

In the instance underneath, I display obtain the report named linuxint.report from the faraway host thru port 3940. The report is saved in the house listing of the faraway consumer named kali which I take advantage of to authenticate, that’s the default faraway location when no different is outlined.

At the top of the command, I specify the native listing wherein the report can be stored (Downloads).

scp -P 3940 kali@192.168.1.100:linuxhint.report ~/Downloads

As you’ll be able to see, the report switch used to be carried out effectively. The reason why explaining 0.0KB/S is that each one information for this instructional are empty.

Downloading Directories Using SCP on a Different Port

Downloading directories calls for an excessively equivalent syntax excluding for the -r flag which should be added moreover to the -P flag as proven within the instance underneath. The screenshot underneath presentations cpu the faraway listing named dir to the native house listing, all the way through port 3049.

scp -rP 3940 kali@192.168.1.100:dir ~/

As you’ll be able to see, the listing used to be downloaded recursively to the native house.

In the instance, underneath I add the linuxhint.report thru port 3940 to the faraway subdirectory named linuxhintdir, situated within the faraway house listing.

scp -P 3940 linuxhint.report kali@192.168.1.100:linuxhintdir

Uploading Directories Using SCP with Different Port

The instance underneath presentations add a listing as an alternative of a typical report. For this function, similar to when importing information, you most effective wish to upload the -r flag.

The following instance presentations add the listing named dir to the /tmp faraway listing thru port 3940.

scp -rP 3940 dir kali@192.168.1.100:/tmp

Yet, it is very important remind readers the SCP command is out of date and changed via more secure possible choices like rsync or sftp. Users should remember that even if the SCP command is according to the SSH protocol, the -P flag should be typed in higher case, opposite to the SSH port specification which is completed the usage of a lowercase -p.

Thank you for studying Linux Hint. I’m hoping this instructional used to be helpful. Keep following us for extra Linux guidelines and tutorials.
