Linux – How to transfer entire directory from one server to another via SSH

linuxssh

I have two servers, access to SSH on both. I want to transfer entire directory from server A to server B.
They are both remote servers to me.

Am I right to assume it is possible to log into SSH terminal on my local PC, connect to server A, and do some magical command that will initiate a transfer between the two servers while being able to log out of terminal on my own local machine?

Best Answer

On server A:

$ scp -r /path/to/directory someuser@serverB:/path/to/files/.

The above command will copy the files from serverA to serverB using someuser (a user on serverB). The directory (/path/to/directory) will be copied as a directory to the directory on serverB into the directory /path/to/files/.

Copy ssh keys from one server to another server

As Ethabell mentioned, you can copy over the current host keys to the new server.

You can find your host keys by opening your sshd_config file (On my Ubuntu 12.04 box its /etc/ssh/sshd_config). In the config file look for the HostKey entries. These entries will tell you where the host key files are located. You should be able to copy these files to the new server and update the new server's sshd_config to point to the copied keys (or just overwrite the files that already exist on the new server).

Also, note this section from the sshd_config man page, specifically the part about permissions:

Specifies a file containing a private host key used by SSH. The default is /etc/ssh/ssh_host_key for protocol version 1, and /etc/ssh/ssh_host_dsa_key, /etc/ssh/ssh_host_ecdsa_key and /etc/ssh/ssh_host_rsa_key for protocol version 2. Note that sshd(8) will refuse to use a file if it is group/world-accessible. It is possible to have multiple host key files. “rsa1” keys are used for version 1 and “dsa”, “ecdsa” or “rsa” are used for version 2 of the SSH protocol.

SSH SFTP: transfer local directory to remote server

scp is plain and simple, if you have rsync, use it, its a lot smarter.

also, drop the -e ssh , as its the default.

i assume you already check the permissions for the correct users in boths sides, so i recommend you first CD the origin directory and run the rsync from there

cd /Applications/MAMP/rest/of/path 
ls -l     # to confirm you are on the right place
rsync -avz --progress --stats  . user@myserver.com:/remote/path
