netrc - file for ftp remote login data
The .netrc file contains data for logging in to a remote
host over the network for file transfers by ftp(1). This file resides
in the user's home directory on the machine initiating the file transfer.
Its permissions should be set to disallow read access by group and others.
See chmod(1).
Tokens can be separated by SPACE, TAB, or
NEWLINE characters. The following tokens are supported:
account string
Supply an additional account password. If this token is
present, the auto-login process supplies the specified string if the remote
server requires an additional account password. If the remote server does not
require an additional account password, the auto-login process initiates an
ACCT command.
default
Same as
machine name, except that default
matches any name. There can be only one
default token, and it must be
after all
machine tokens. The
default token is normally used as
follows:
default login anonymous password user@site
Such an entry gives the user automatic anonymous ftp login
to machines not specified in .netrc.
login name
Identify a user on the remote machine. If this token is
present, the auto-login process initiates a login using the specified
name.
machine name
Identify a remote machine name. The auto-login process
searches the .netrc file for a machine token that matches the
remote machine specified on the ftp command line or as an open
command argument. Once a match is made, the subsequent .netrc tokens
are processed, stopping when the EOF is reached or another
machine token is encountered.
macdef name
Define a macro. This token functions the same as
ftp macdef. A macro is defined with the specified name; its
contents begin with the next .netrc line and continue until a null line
(consecutive NEWLINE characters) is encountered. If a macro named
init is defined, it is automatically executed as the last step in the
auto-login process.
password string
Supply a password. If this token is present, the
auto-login process supplies the specified string if the remote server requires
a password as part of the login process. If this token is present in the
.netrc file, ftp aborts the auto-login process if the
.netrc is readable by anyone besides the user.
skipsyst
Skip the
SYST command that is sent by default to
all remote servers upon connection. The system command is what enables the
automatic use of binary mode rather than the protocol default ascii mode.
As some older servers cannot handle the ftp command, this
directive is provided to allow inter-operability with these servers.
Example 1 A Sample .netrc File
A .netrc file containing the following line:
machine ray login demo password mypassword
allows an autologin to the machine ray using the login name
demo with password mypassword.
