Net::Config(3)        User Contributed Perl Documentation       Net::Config(3)
NAME
       Net::Config - Local configuration data for libnet
SYNOPSIS
           use Net::Config qw(%NetConfig);
DESCRIPTION
       "Net::Config" holds configuration data for the modules in the libnet
       distribution. During installation you will be asked for these values.
       The configuration data is held globally in a file in the perl
       installation tree, but a user may override any of these values by
       providing their own. This can be done by having a ".libnetrc" file in
       their home directory. This file should return a reference to a HASH
       containing the keys described below.  For example
           # .libnetrc
           {
               nntp_hosts => [ "my_preferred_host" ],
               ph_hosts   => [ "my_ph_server" ],
           }
           __END__
METHODS
       "Net::Config" defines the following methods. They are methods as they
       are invoked as class methods. This is because "Net::Config" inherits
       from "Net::LocalCfg" so you can override these methods if you want.
       requires_firewall ( HOST )
           Attempts to determine if a given host is outside your firewall.
           Possible return values are.
             -1  Cannot lookup hostname
              0  Host is inside firewall (or there is no ftp_firewall entry)
              1  Host is outside the firewall
           This is done by using hostname lookup and the "local_netmask" entry
           in the configuration data.
NetConfig VALUES
       nntp_hosts
       snpp_hosts
       pop3_hosts
       smtp_hosts
       ph_hosts
       daytime_hosts
       time_hosts
           Each is a reference to an array of hostnames (in order of
           preference), which should be used for the given protocol
       inet_domain
           Your internet domain name
       ftp_firewall
           If you have an FTP proxy firewall (NOT an HTTP or SOCKS firewall)
           then this value should be set to the firewall hostname. If your
           firewall does not listen to port 21, then this value should be set
           to "hostname:port" (eg "hostname:99")
       ftp_firewall_type
           There are many different ftp firewall products available. But
           unfortunately there is no standard for how to traverse a firewall.
           The list below shows the sequence of commands that Net::FTP will
           use
             user        Username for remote host
             pass        Password for remote host
             fwuser      Username for firewall
             fwpass      Password for firewall
             remote.host The hostname of the remote ftp server
           0   There is no firewall
           1
                    USER user AT remote.host
                    PASS pass
           2
                    USER fwuser
                    PASS fwpass
                    USER user AT remote.host
                    PASS pass
           3
                    USER fwuser
                    PASS fwpass
                    SITE remote.site
                    USER user
                    PASS pass
           4
                    USER fwuser
                    PASS fwpass
                    OPEN remote.site
                    USER user
                    PASS pass
           5
                    USER user@fwuser AT remote.site
                    PASS pass@fwpass
           6
                    USER fwuser AT remote.site
                    PASS fwpass
                    USER user
                    PASS pass
           7
                    USER user AT remote.host
                    PASS pass
                    AUTH fwuser
                    RESP fwpass
       ftp_ext_passive
       ftp_int_passive
           FTP servers can work in passive or active mode. Active mode is when
           you want to transfer data you have to tell the server the address
           and port to connect to.  Passive mode is when the server provide
           the address and port and you establish the connection.
           With some firewalls active mode does not work as the server cannot
           connect to your machine (because you are behind a firewall) and the
           firewall does not re-write the command. In this case you should set
           "ftp_ext_passive" to a true value.
           Some servers are configured to only work in passive mode. If you
           have one of these you can force "Net::FTP" to always transfer in
           passive mode; when not going via a firewall, by setting
           "ftp_int_passive" to a true value.
       local_netmask
           A reference to a list of netmask strings in the form
           "134.99.4.0/24".  These are used by the "requires_firewall"
           function to determine if a given host is inside or outside your
           firewall.
       The following entries are used during installation & testing on the
       libnet package
       test_hosts
           If true then "make test" may attempt to connect to hosts given in
           the configuration.
       test_exists
           If true then "Configure" will check each hostname given that it
           exists
