Yep, the network on this machine is already configured:

Code:
bash-2.05a# ifconfig -au
en0: flags=4e080863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST,GROUPRT,64BIT,PSEG>
        inet 192.168.2.7 netmask 0xffffff00 broadcast 192.168.2.255
lo0: flags=e08084b<UP,BROADCAST,LOOPBACK,RUNNING,SIMPLEX,MULTICAST,GROUPRT,64BIT>
        inet 127.0.0.1 netmask 0xff000000 broadcast 127.255.255.255
        inet6 ::1/0
         tcp_sendspace 65536 tcp_recvspace 65536

This is the output of the debug mode:

Code:
bash-2.05a# which sshd
/usr/sbin/sshd
bash-2.05a# /usr/sbin/sshd -D -d -e

IPv4Addr(3pm)						User Contributed Perl Documentation					     IPv4Addr(3pm)

NAME
Net::IPv4Addr - Perl extension for manipulating IPv4 addresses. SYNOPSIS
use Net::IPv4Addr qw( :all ); my ($ip,$cidr) = ipv4_parse( "127.0.0.1/24" ); my ($ip,$cidr) = ipv4_parse( "192.168.100.10 / 255.255.255.0" ); my ($net,$msk) = ipv4_network( "192.168.100.30" ); my $broadcast = ipv4_broadcast( "192.168.100.30/26" ); if ( ipv4_in_network( "192.168.100.0", $her_ip ) ) { print "Welcome !"; } etc. DESCRIPTION
Net::IPv4Addr provides functions for parsing IPv4 addresses both in traditional address/netmask format and in the new CIDR format. There are also methods for calculating the network and broadcast address and also to check if a given address is in a specific network. ADDRESSES
All of Net::IPv4Addr functions accept addresses in many formats. The parsing is very liberal. All these addresses would be accepted: 127.0.0.1 192.168.001.010/24 192.168.10.10/255.255.255.0 192.168.30.10 / 21 10.0.0.0 / 255.0.0.0 255.255.0.0 Those wouldn't though: 272.135.234.0 192.168/16 Most functions accepts the address and netmask or masklength in the same scalar value or as separate values. That is either my($ip,$masklength) = ipv4_parse($cidr_str); my($ip,$masklength) = ipv4_parse($ip_str,$msk_str); USING
No functions are exported by default. Either use the ":all" tag to import them all or explicitly import those you need. FUNCTIONS
ipv4_parse my ($ip,$msklen) = ipv4_parse($cidr_str); my $cidr = ipv4_parse($ip_str,$msk_str); my ($ip) = ipv4_parse($ip_str,$msk_str); Parse an IPv4 address and return in scalar context the address in CIDR format, in an array context the address and the mask length. If the parameters doesn't contains a netmask or a mask length, in scalar context only the IPv4 address is returned and in an array context the mask length is undefined. If the function cannot parse its input, it croaks. Trap it using "eval" if you don't like that. ipv4_broadcast my ($broadcast) = ipv4_broadcast($ip_str); my $broadcast = ipv4_broadcast($ip_str,$msk_str); This function returns the broadcast address. If the input doesn't contain a netmask or mask length, the default netmask is assumed. This function croaks if the input is invalid. ipv4_network my $cidr = ipv4_network($ip_str); my $cidr = ipv4_network($cidr_str); my ($net,$msk) = ipv4_network( $net_str, $msk_str); In scalar context, this function returns the network in CIDR format in which the address is. In array context, it returns the network address and its mask length as a two elements array. If the input is a host without a netmask or mask length, the default netmask is assumed. Again, the function croaks if the input is invalid. ipv4_in_network print "Yes" if ipv4_in_network( $cidr_str1, $cidr_str2); print "Yes" if ipv4_in_network( $ip_str1, $mask_str1, $cidr_str2 ); print "Yes" if ipv4_in_network( $ip1, $mask1, $ip2, $msk2 ); This function checks if the second network is contained in the first one and it implements the following semantics : If net1 or net2 is a magic address (0.0.0.0 or 255.255.255.255) then this function returns true. If net1 is a host, net2 will be in the same net only if it is the same host. If net2 is a host, it will be contained in net1 only if it is part of net1. net2 is only part of net1 if it is entirely contained in net1. Trap bad input with "eval" or else. ipv4_chkip if ($ip = ipv4_chkip($str) ) { # Do something } Return the IPv4 address in the string or undef if the input doesn't contain a valid IPv4 address. ipv4_cidr2msk my $netmask = ipv4_cidr2msk( $cidr ); Returns the netmask corresponding to the mask length given in the input. As usual, croaks if it doesn't like your input (in this case a number between 0 and 32). ipv4_msk2cidr my $masklen = ipv4_msk2cidr( $msk ); Returns the mask length of the netmask in the input. As usual, croaks if it doesn't like your input. AUTHOR
