TIMEOUT - Time Out in seconds.
CHAIN_LEN - Length of chain.
DEBUG - Debug level ( 0x00 | 0x01 | 0x02 | 0x04 ) 0x00 - Off 0x01 - Debug On 0x02 - Write all answers of socks servers. 0x04 - Write all requests of socks servers. 0x08 - Extended error information.
CHAIN_FILE - Configuration file name.
LOG_FILE - Log file name. if undef, writing all errors to STDERR or `syslogd`
RANDOM_CHAIN - Rule for create the chains ( 0 || 1 ). 0 - create chain by index... 1 - create chain by random...
CHECK_DELAY - Delay time for the next usage this proxy if the last connection failed ( in seconds )
AUTO_SAVE - Auto save the data of chain to the cache file.
LOG_FH - File Descriptor of LOG file.
Create new connection to remote host.
Usage:
die unless $self->connect( $peer_host, $peer_port ) == SOCKS_OKAY;
Binding port.
Usage:
die unless $self->bind( $peer_host, $peer_port ) == SOCKS_OKAY;
Accepting connection over SOCKS
Usage:
die unless $self->accept() == SOCKS_OKAY; $sh = $self->sh;
Returns the sock handle
Usage:
$sh = $self->sh;
Close the connection.
Usage:
$self->close;
Returns [ and modify ] the current configuration options.
Usage: # Change TIMEOUT $self->configure( TIMEOUT => 10 );
# Returns TIMEOUT $timeout = $self->configure( 'TIMEOUT' );
Returns parameters of the last server into the chain socks...
Usage:
$listen_addr = $self->socks_param( 'listen_Addr' );
or:
$all_param = $self->socks_param(); $listen_addr = $all_param->{'listen_addr'};
socks_error( ERROR_CODE )
Returns the error message.

$self->read_chain_data();
Reading the configuration file.
$self->get_socks_count
Returns the number of the socks servers
$self->mark_proxy ( $proxy_id, $status );
Mark the socks server with index $proxy_id how dead if $status not equally SOCKS_OKAY, otherwise clearing counter of the connection failure...
$self->dump_cfg_data();
Dump socks data, in the cache file.
$self->restore_cfg_data();
Restore socks data, from the cache file.
accept method change the follow variable, which returns of the socks_param:
listen_addr listen_port
Methods connect, bind, accept returnings SOCKS_OKAY if it succeeded.
