NAME
netrc - file for ftp remote login data
DESCRIPTION
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 charac-
ters. 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 ini-
tiates an ACT 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 nor-
mally 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 com-
mand 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 con-
tinue until a null line (consecutive NEW-
LINE 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 any-
one besides the user.
skipsyst Skip the SYST command that is sent by
default to all remote servers upon con-
nection. 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.
EXAMPLES
Example 1 A Sample .netrc File
