Symmetricom S100 manual Psftp.Exe

DOS Prompt (in 95, 98, ME) or the Command Prompt (in NT, 2000). This is available from the Programs section of your Start Menu.

To start PSCP, add the directory containing PSCP to your PATH environment variable, enter the following in the console window:

set PATH=C:\path\to\putty\directory;%PATH%

This will only work for the lifetime of that particular console window. To set your PATH more permanently on Windows NT, use the Environment tab of the System Control Panel. On Windows 95, 98, and ME, you will need to edit your AUTOEXEC.BAT to include a set command like the one above.

Further, PSCP.EXE is a command line application, not a GUI application. If you run it without arguments, it will simply print a help message and terminate. It runs on every SSH server. PSCP is designed to do a single file transfer operation and immediately terminate.

PSFTP.EXE

is a tool for transferring files securely between computers using an SSH connection. PSFTP differs from PSCP in the following ways:

•PSFTP uses the new SFTP protocol, which is a feature of SSH 2 only (PSCP will also use this protocol if it can, but there is an SSH 1 equivalent it can fall back to if it cannot).

•PSFTP allows you to run an interactive file transfer session, much like the Windows FTP program.

You can list the contents of directories, browse around the file system, issue multiple get and put commands, and eventually log out.

PLINK.EXE

is a command line connection tool similar to UNIX SSH. It is mostly used for automated operations, such as making CVS access a repository on a remote server. Do not use Plink if you want to run an interactive session in a console window. Plink is a command line application in the same manner as PSCP.

PAGEANT.EXE

is for public-key authentication and allows open multiple SSH sessions without having to type a pass phrase every time. It provides you with the security benefit of never storing a decrypted private key on disk. Holding your decrypted private keys in Pageant is better than storing them in disk files. The drawbacks are:

•Windows does not protect pieces of memory from being written to the system swap file. If Pageant is holding your private keys, it's possible that decrypted private key data may be written to the system swap file, and an intruder who gained access to your hard disk might be able to recover that data.
