Holds configuration data for the
modules in the libnet distribution. Net::Config builds this
configuration interactively at install time of libnet, and the
Net::Config file is further queried when you use modules such as
Net::FTP. This module is part of the core Perl distribution starting
with Perl 5.8.
Net::Config stores the following values (which can be
daytime_hosts, and time_hosts.
Each is a reference to an array of hostnames (in order of
preference), which should be used for the given protocol. You can
override any of the Net::Config values when you use any of the
modules that live under the libnet umbrella. In addition, you can
maintain your own .libnetrc to hold your custom
values all the time. A sample .libnetrc follows:
$ cat .libnetrc
nntp_hosts => [ "news.my.host", "news.their.host" ]
_ _END_ _
In addition to the options listed previously, the following options
can be specified:
Your Internet domain name.
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 on port 21, then this value should be set to
An integer from 1 to 7 signifying the sequence of commands that
Net::FTP will use to traverse a firewall, as follows:
There is no firewall (default).
FTP servers normally work in a nonpassive mode: when you want to
transfer data, you have to tell the server the address and port to
connect to. This becomes a problem because some servers cannot
connect to your machine through the second port because
it's being used by the FTP connection. In this case,
set ftp_ext_passive to true.
If your server is configured to only work in passive mode, you can
force Net::FTP to always transfer in passive mode when not going via
a firewall by setting ftp_int_passive to true.
A reference to a list of netmask strings. To be used by the
requires_firewall function to determine if a
given host is inside or outside your firewall.
The following method is supported by Net::Config.
Determines if host is outside of your
firewall. Possible return values are:
Cannot look up hostname
Host is inside firewall (or there is no
Host is outside the firewall
