Net::Config - Local configuration data for libnet |
NAME
Net::Config - Local configuration data for libnet
SUPPORTED PLATFORMS
- Linux
- Solaris
- Windows
SYNOPSYS
use Net::Config qw(%NetConfig);
DESCRIPTION
Net::Config holds configuration data for the modules in the libnet
distribuion. 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 thier own. This
can be done by having a .libnetrc file in thier home directory. This file
should return a reference to a HASH containing the keys described below.
For example
# .libnetrc
{
nntp_hosts => [ "my_prefered_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_netmaskentry 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 a 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_ext_passive
- ftp_int_pasive
-
FTP servers normally work on a non-passive mode. That is when you want to
transfer data you have to tell the server the address and port to
connect to.
With some firewalls this does not work as te server cannot connect to your machine (because you are beind a firewall) and the firewall does not re-write te command. In this case you should set
ftp_ext_passiveto a true value.Some servers are configured to only work in passive mode. If you have one of these you can force
Net::FTPto always transfer in passive mode, when not going via a firewall, by cettingftp_int_passiveto 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 therequires_firewallfunction 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 them
make testmay attempt to connect to hosts given in the configuration. - test_exists
-
If true the
Configurewill check each hostname given that it exists
