scp	[-346ABCpqrTv] [-ccipher] [-Fssh_config] [-iidentity_file] [-Jdestination] [-llimit] [-ossh_option] [-Pport] [-Sprogram] source .. target

I used scp and ssh commands here with ssh keys for passwordless authentication. The ssh key was created on the source system as below. Is this the correct and secured way of creating an ssh key? # ssh-keygen -t rsa -N ' -f /.ssh/mytest.key The key was copied from the source to target system with executing below command. I have found it easiest to use a graphical interface on windows (I recommend mobaXTerm it has ssh, scp, ftp, remote desktop, and many more) but if you are set on command line I would recommend cd'ing into the directory with the source folder then.

scp copies files between hosts on a network.

It uses ssh(1) for data transfer, and uses the same authentication and provides the same security as a login session. The scp protocol requires execution of the remote user's shell to perform glob(3) pattern matching.

scp will ask for passwords or passphrases if they are needed for authentication. Mudlarksa postmortem.

The source and target may be specified as a local pathname, a remote host with optional path in the form [user@]host:[path], or a URI in the form scp://[user@]host[:port][/path]. Local file names can be made explicit using absolute or relative pathnames to avoid scp treating file names containing ‘:’ as host specifiers.

When copying between two remote hosts, if the URI format is used, a port may only be specified on the target if the -3 option is used.

The options are as follows:

-3

Copies between two remote hosts are transferred through the local host. Without this option the data is copied directly between the two remote hosts. Note that this option disables the progress meter and selects batch mode for the second host, since scp cannot ask for passwords or passphrases for both hosts.

-4

Forces scp to use IPv4 addresses only.

-6

Forces scp to use IPv6 addresses only.

-A

Allows forwarding of ssh-agent(1) to the remote system. The default is not to forward an authentication agent.

-B

Selects batch mode (prevents asking for passwords or passphrases).

-C

Compression enable. Passes the -C flag to ssh(1) to enable compression.

-ccipher

Selects the cipher to use for encrypting the data transfer. This option is directly passed to ssh(1).

-Fssh_config

Specifies an alternative per-user configuration file for ssh. This option is directly passed to ssh(1).

-iidentity_file

Selects the file from which the identity (private key) for public key authentication is read. This option is directly passed to ssh(1).

-Jdestination

Connect to the target host by first making an scp connection to the jump host described by destination and then establishing a TCP forwarding to the ultimate destination from there. Multiple jump hops may be specified separated by comma characters. This is a shortcut to specify a ProxyJump configuration directive. This option is directly passed to ssh(1).

-llimit

Limits the used bandwidth, specified in Kbit/s.

-ossh_option

Can be used to pass options to ssh in the format used in ssh_config(5). This is useful for specifying options for which there is no separate scp command-line flag. For full details of the options listed below, and their possible values, see ssh_config(5).

-Pport

Specifies the port to connect to on the remote host. Note that this option is written with a capital ‘P’, because -p is already reserved for preserving the times and modes of the file.

-p

Preserves modification times, access times, and modes from the original file.

-q

Quiet mode: disables the progress meter as well as warning and diagnostic messages from ssh(1).

-r

Recursively copy entire directories. Note that scp follows symbolic links encountered in the tree traversal.

-Sprogram

Openssh Scp Deprecated

Name of program to use for the encrypted connection. The program must understand ssh(1) options.

-T

Disable strict filename checking. By default when copying files from a remote host to a local directory scp checks that the received filenames match those requested on the command-line to prevent the remote end from sending unexpected or unwanted files. Because of differences in how various operating systems and shells interpret filename wildcards, these checks may cause wanted files to be rejected. This option disables these checks at the expense of fully trusting that the server will not send unexpected filenames.

-v

Openssh Scp Server

Verbose mode. Causes scp and ssh(1) to print debugging messages about their progress. This is helpful in debugging connection, authentication, and configuration problems.

The scp utility exits 0 on success, and >0 if an error occurs.

Openssh Scp Command

sftp(1), ssh(1), ssh-add(1), ssh-agent(1), ssh-keygen(1), ssh_config(5), sshd(8)

scp is based on the rcp program in BSD source code from the Regents of the University of California.
