Most options have corresponding configuration options that can be set in the configuration file. For example with the -c option you can designate which encryption method you want to use for instance idea des blowfish or arcfour. With the -i option you can select a particular private key to use. The -C option enables you to have transmissions compressed at specified levels. See the ssh man page for a complete list of options. scp You use scp to copy files from one host to another on a network. Designed to replace rcp scp uses ssh to transfer data and employs the same authentication and encryption methods. If authentication requires it scp requests a password or passphrase. The scp program operates much like rcp. Directories and files on remote hosts are specified using the username and the host address before the filename or directory. The username specifies the remote user account that scp is accessing and the host is the remote system where that account is located. You separate the user from the host address with an @ and you separate the host address from the file or directory name with a colon. The following example copies the file party from a user s current directory to the user aleina s birthday directory located on the host scp party aleina@ birthday party Of particular interest is the -r recursive option which enables you to copy whole directories. See the scp man page for a complete list of options. In the next example the user copies the entire reports directory to the user justin s projects directory scp -r reports justin@ projects In the next example the user george copies the mydocl file from the user cecelia s home directory george@turtle george scp cecelia@ mydoc1 . cecelia@ s password mydoc1 0 0 -- -- eTa mydoc1 100 17 00 00 george@turtle george .
