Transfer files with SSH. centos 6

     

In the following example we will use SCP (Secure Copy) to transfer the files.

# scp [Option] Source Target

# copy the [clado.txt] on local to remote server [easylinuxalways.com]

[clado@easylinux ~]$ scp ./clado.txt clado@easylinuxalways.com:~/

clado@easylinuxalways.com's password:# password of the user

clado.txt                                                100%   10     0.0KB/s   00:00

# copy the [/home/clado/clado.txt] on remote server [easylinuxalways.com] to the local

[clado@easylinux ~]$ scp clado@easylinuxalways.com:/home/clado/clado.txt ./clado.txt

clado@easylinuxalways.com's password:

clado.txt                                                100%   10     0.0KB/s   00:00

In the following example we use SFTP (SSH File Transfer Protocol).

SFTP server function is enabled by default but if not, enable it to add the line [Subsystem sftp /usr/libexec/openssh/sftp-server] in [/etc/ssh/sshd_config].

# sftp [Option] [user@host]

[clado@easylinux ~]$ sftp clado@easylinuxalways.com

clado@easylinuxalways.com's password:# password of the user

Connected to easylinuxalways.com.
