- (djm) OpenBSD CVS updates: - deraadt@cvs.openbsd.org 2000/08/18 20:07:23 [ssh.c] accept remsh as a valid name as well; roman@buildpoint.com - deraadt@cvs.openbsd.org 2000/08/18 20:17:13 [deattack.c crc32.c packet.c] rename crc32() to ssh_crc32() to avoid zlib name clash. do not move to libz crc32 function yet, because it has ugly "long"'s in it; oneill@cs.sfu.ca - deraadt@cvs.openbsd.org 2000/08/18 20:26:08 [scp.1 scp.c] -S prog support; tv@debian.org - deraadt@cvs.openbsd.org 2000/08/18 20:50:07 [scp.c] knf - deraadt@cvs.openbsd.org 2000/08/18 20:57:33 [log-client.c] shorten - markus@cvs.openbsd.org 2000/08/19 12:48:11 [channels.c channels.h clientloop.c ssh.c ssh.h] support for ~. in ssh2 - deraadt@cvs.openbsd.org 2000/08/19 15:29:40 [crc32.h] proper prototype - markus@cvs.openbsd.org 2000/08/19 15:34:44 [authfd.c authfd.h key.c key.h ssh-add.1 ssh-add.c ssh-agent.1] [ssh-agent.c ssh-keygen.c sshconnect1.c sshconnect2.c Makefile] [fingerprint.c fingerprint.h] add SSH2/DSA support to the agent and some other DSA related cleanups. (note that we cannot talk to ssh.com's ssh2 agents) - markus@cvs.openbsd.org 2000/08/19 15:55:52 [channels.c channels.h clientloop.c] more ~ support for ssh2 - markus@cvs.openbsd.org 2000/08/19 16:21:19 [clientloop.c] oops - millert@cvs.openbsd.org 2000/08/20 12:25:53 [session.c] We have to stash the result of get_remote_name_or_ip() before we close our socket or getpeername() will get EBADF and the process will exit. Only a problem for "UseLogin yes". - millert@cvs.openbsd.org 2000/08/20 12:30:59 [session.c] Only check /etc/nologin if "UseLogin no" since login(1) may have its own policy on determining who is allowed to login when /etc/nologin is present. Also use the _PATH_NOLOGIN define. - millert@cvs.openbsd.org 2000/08/20 12:42:43 [auth1.c auth2.c session.c ssh.c] Add calls to setusercontext() and login_get*(). We basically call setusercontext() in most places where previously we did a setlogin(). Add default login.conf file and put root in the "daemon" login class. - millert@cvs.openbsd.org 2000/08/21 10:23:31 [session.c] Fix incorrect PATH setting; noted by Markus.

.Sh DESCRIPTION
|
|
.Nm
|
|
copies files between hosts on a network.
|
|
It uses
|
|
.Xr ssh 1
|
|
for data transfer, and uses the same authentication and provides the
|
|
same security as
|
|
.Xr ssh 1 .
|
|
Unlike
|
|
.Xr rcp 1 ,
|
|
.Nm
|
|
will ask for passwords or passphrases if they are needed for
|
|
authentication.
|
|
.Pp
|
|
Any file name may contain a host and user specification to indicate
|
|
that the file is to be copied to/from that host.
|
|
Copies between two remote hosts are permitted.
|
|
.Pp
|
|
The options are as follows:
|
|
.Bl -tag -width Ds
|
|
.It Fl c Ar cipher
|
|
Selects the cipher to use for encrypting the data transfer.
|
|
This option is directly passed to
|
|
.Xr ssh 1 .
|
|
.It Fl i Ar identity_file
|
|
Selects the file from which the identity (private key) for RSA
|
|
authentication is read.
|
|
This option is directly passed to
|
|
.Xr ssh 1 .
|
|
.It Fl p
|
|
Preserves modification times, access times, and modes from the
|
|
original file.
|
|
.It Fl S
|
|
Name of program to use for the encrypted connection.
|
|
The program must understand
|
|
.Xr ssh 1
|
|
options.
|
|
.It Fl r
|
|
Recursively copy entire directories.
|
|
.It Fl v
|
|
Verbose mode.
|
|
Causes
|
|
.Nm
|
|
and
|
|
.Xr ssh 1
|
|
to print debugging messages about their progress.
|
|
This is helpful in
|
|
debugging connection, authentication, and configuration problems.
|
|
.It Fl B
|
|
Selects batch mode (prevents asking for passwords or passphrases).
|
|
.It Fl q
|
|
Disables the progress meter.
|
|
.It Fl C
|
|
Compression enable.
|
|
Passes the
|
|
.Fl C
|
|
flag to
|
|
.Xr ssh 1
|
|
to enable compression.
|
|
.It Fl P Ar port
|
|
Specifies the port to connect to on the remote host.
|
|
Note that this option is written with a capital
|
|
.Sq P ,
|
|
because
|
|
.Fl p
|
|
is already reserved for preserving the times and modes of the file in
|
|
.Xr rcp 1 .
|
|
.It Fl S
|
|
Name of program to use for the encrypted connection. The program must
|
|
understand
|
|
.Xr ssh 1
|
|
options.
|
|
.It Fl 4
|
|
Forces
|
|
.Nm
|
|
to use IPv4 addresses only.
|
|
.It Fl 6
|
|
Forces
|
|
.Nm
|
|
to use IPv6 addresses only.
