NAME
Net::Netrc - OO interface to users netrc file
SYNOPSIS
use Net::Netrc; $mach = Net::Netrc->lookup(some.machine); $login = $mach->login; ($login, $password, $account) = $mach->lpa;
DESCRIPTION
Net::Netrc is a class implementing a simple interface to the .netrc
file used as by the ftp program.
Net::Netrc also implements security checks just like the ftp program,
these checks are, first that the .netrc file must be owned by the user
and second the ownership permissions should be such that only the owner
has read and write access. If these conditions are not met then a
warning is output and the .netrc file is not read.
The .netrc File
The .netrc file contains login and initialization information used by the auto-login process. It resides in the user’s home directory. The following tokens are recognized; they may be separated by spaces, tabs, or new-lines:
- 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. Once a match is made, the subsequent .netrc tokens are processed, stopping when the end of file is reached or an- other machine or a default token is encountered.
- default
- This is the 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. This is normally used as: default login anonymous password user@site thereby giving the user automatic anonymous 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 will initiate a login using the specified name.
- password string
- Supply a password. If this token is present, the auto-login process will supply the specified string if the remote server requires a password as part of the login process.
- account string
- Supply an additional account password. If this token is present, the auto-login process will supply the specified string if the remote server requires an additional account password.
- macdef name
- Define a macro.
Net::Netrconly parses this field to be compatible with ftp.
Class Methods
The constructor for a Net::Netrc object is not called new as it does
not really create a new object. But instead is called lookup as this
is essentially what it does.
- “lookup($machine[, $login])”
- Lookup and return a reference to the
entry for
$machine. If$loginis given then the entry returned will have the given login. If$loginis not given then the first entry in the .netrc file for$machinewill be returned. If a matching entry cannot be found, and a default entry exists, then a reference to the default entry is returned. If there is no matching entry found and there is no default defined, or no .netrc file is found, thenundefis returned.
Object Methods
- “login()”
- Return the login id for the netrc entry
- “password()”
- Return the password for the netrc entry
- “account()”
- Return the account information for the netrc entry
- “lpa()”
- Return a list of login, password and account information for the netrc entry
