2 Linux/Unix/Mac commandline sftp/scp Usage Examples
> sftp firstname.lastname@example.org Connecting to bwfilestorage.lsdf.kit.edu<br> email@example.com's password: sftp> ls snapshots temp test sftp> help ... sftp> put myfile sftp> get myfile
> scp mylocalfile firstname.lastname@example.org: # copies to home directory
3 Using SFTP from Windows and Mac graphical clients
Windows clients do not have a SCP/SFTP client installed by default, so it needs to be installed before this protocol can be used.
network drive over SFTP:
- WebDrive (for Windows and Mac)
- SFTP Net Drive (ELDOS) (for Windows)
- NetDrive (for Windows)
- ExpanDrive (for Windows and Mac)
Start FileZilla, Select "File -> Site Manager..." from the main menu and set up a new connection with the following settings:
Protocol: SFTP - SSH File Transfer Protocol Host: <hostname> Logon Typ: Interactive User: <username>
Note: By default Filezilla will close the connection after 20 seconds of inactivity. In order to increase or disable this timeout, select "Edit -> Settings ... -> Connections" and increase "Timeout in seconds" to a reasonable value or set to 0 to disable connection timeout.
4 Best practices
Encrypting all the transferred data via scp/sftp takes time, which can become significant for really large data transfers.
In these cases, you can choose a faster encryption cipher to speed up that part of your data transfer via options to ssh/sftp. In our tests, these ciphers have had the listed transfer speedups over the default. If speedups are noticeable for you depends on processor type, network connection and the used hard disk.
With ssh/sshfs you can use different ciphers with the -c option:
ssh -c email@example.com
A list of available ciphers should be available with the command
ssh -Q cipher
