sftp is an ftp replacement that runs over an ssh tunnel. Two programs are
|
|
included - sftp and sftpserv. When sftp is run and a host is connected to
|
|
(either by running 'sftp remotehost' or 'open remotehost' from the sftp
|
|
prompt), an ssh connection is initiated to the remote host, and sftpserv is
|
|
run. So, sftpserv must be in your path on the remote host. Note that since
|
|
sftpserv is run from ssh, no root privileges are necessary. By default,
|
|
sftpserv is expected to be in $PATH on the remote host. This can be overriden
|
|
by passing '--enable-remotepath=<path>' to configure or using the
|
|
'-P remotepath' option to sftp. To run as a different user, use the
|
|
'-l remoteuser' option. To connect to an alternate port with ssh,
|
|
use the '-p remoteport' option. To enable ssh compression, use '-C'.
|
|
|
|
From within sftp, all of the normal ftp commands are present: open, close, get,
|
|
put, mget, mput, cd, ls, dir, lcd, delete, rm, pwd, quit. There's also exec,
|
|
which runs a program on the remote end. This program must not accept input
|
|
('exec ls' is ok, but 'exec vi' is not). To run local commands, precede them
|
|
with a '!'.
|
|
|
|
When building sftp, a link is made to rsftp, which uses rsh instead of ssh.
|
|
sftp has been tested with rsh (with and without .rhosts) and ssh1 (with
|
|
ssh-agent, password, and RSA authentication). I haven't tested ssh2, but it
|
|
should work. The login process is a bit of a hack, so if logging in doesn't
|
|
work, it's a bug and should be fixed.
|
|
|
|
sftp uses a fairly simple multiplexed protocol over an SSH channel. The server
|
|
is a state machine, and is far more capable than the client. As an example,
|
|
the server theoretically could handle multiple concurrent file transfers, but
|
|
the client will only send one.
|
|
|
|
This was mostly written during the summer of 1998, and resurrected in October,
|
|
1999. I don't know how much time I want to spend adding new features, but
|
|
bugs will be fixed.
