For more information see examples: telnet_over_socks_chain.pl and accept_over_socks_chain.pl
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.
CHAIN_FILE_DATA - Array reference. ( a format same as well as
in a file of a configuration ). It is possible
to use for data transmission about chains directly,
without use of a file of a configuration. At use
of the given parameter, parameter CHAIN_FILE is
ignored, that is the file of a configuration
is not read.
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.
SYSLOG - 1 - Use syslogd ( for *nix ), or eventlog
( for win32 ) for debug messages. Default 0.
HTTP_CLIENT - User-Agent name for http proxies
Usage:
die unless $self->connect( $peer_host, $peer_port ) == SOCKS_OKAY;
Usage:
die unless $self->bind( $peer_host, $peer_port ) == SOCKS_OKAY;
Usage:
die unless $self->accept() == SOCKS_OKAY; $sh = $self->sh;
Usage:
$sh = $self->sh;
Usage:
$self->close;
Usage: # Change TIMEOUT $self->configure( TIMEOUT => 10 );
# Returns TIMEOUT $timeout = $self->configure( 'TIMEOUT' );
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.
Socks error codes:
SOCKS_GENERAL_SOCKS_SERVER_FAILURE
SOCKS_CONNECTION_NOT_ALLOWED_BY_RUL
SOCKS_NETWORK_UNREACHABLE
SOCKS_HOST_UNREACHABLE
SOCKS_CONNECTION_REFUSED
SOCKS_TTL_EXPIRED
SOCKS_COMMAND_NOT_SUPPORTED
SOCKS_ADDRESS_TYPE_NOT_SUPPORTED
SOCKS_OKAY
SOCKS_FAILED
SOCKS_NO_IDENT
SOCKS_USER_MISMATCH
SOCKS_INCOMPLETE_AUTH
SOCKS_BAD_AUTH
SOCKS_SERVER_DENIES_AUTH_METHOD
SOCKS_MISSING_SOCKS_SERVER_NET_DATA
SOCKS_MISSING_PEER_NET_DATA
SOCKS_SOCKS_SERVER_UNAVAILABLE
SOCKS_TIMEOUT
SOCKS_UNSUPPORTED_PROTOCOL_VERSION
SOCKS_UNSUPPORTED_ADDRESS_TYPE
SOCKS_HOSTNAME_LOOKUP_FAILURE
$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.
Http proxies do not support bind method.
Http proxies support only Basic auth.

You can use the comments in the configuration file, for this you must write `#' in the beginning of string...
