This module provides a standard socket-like interface for Python for tunneling connections through SOCKS proxies. =============================================================================== Minor modifications made by Christopher Gilbert (http://motomastyle.com/) for use in PyLoris (http://pyloris.sourceforge.net/) Minor modifications made by Mario Vilas (http://breakingcode.wordpress.com/) mainly to merge bug fixes found in Sourceforge Modifications made by Anorov (https://github.com/Anorov) -Forked and renamed to PySocks -Fixed issue with HTTP proxy failure checking (same bug that was in the old ___recvall() method) -Included SocksiPyHandler (sockshandler.py), to be used as a urllib2 handler, courtesy of e000 (https://github.com/e000): https://gist.github.com/869791#file_socksipyhandler.py -Re-styled code to make it readable -Aliased PROXY_TYPE_SOCKS5 -> SOCKS5 etc. -Improved exception handling and output -Removed irritating use of sequence indexes, replaced with tuple unpacked variables -Fixed up Python 3 bytestring handling - chr(0x03).encode() -> b"" -Other general fixes -Added clarification that the HTTP proxy connection method only supports CONNECT-style tunneling HTTP proxies -Various small bug fixes � )� b64encode)�Callable)� EOPNOTSUPP�EINVAL�EAGAINN)�BytesIO)�SEEK_CURz1.6.7�nt� z8To run PySocks on Windows you must install win_inet_pton� � )�SOCKS4�SOCKS5�HTTPc s t j� �� fdd��}|S )Nc sp | d }zNy$|j � }|dkr&|jd� � | |�S tk rR } z� W Y d d }~X nX W d |dkrj|jd� X d S )Nr TF)� gettimeout� setblocking� Exception)�args�kwargs�selfZ _is_blocking�e)�function� �/usr/lib/python3.6/socks.py�wrapper] s z"set_self_blocking.<locals>.wrapper)� functools�wraps)r r r )r r �set_self_blocking[ s r c @ s" e Zd ZdZddd�Zdd� ZdS )� ProxyErrorz4Socket_err contains original socket.error exception.Nc C s( || _ || _|r$| j dj|�7 _ d S )Nz: {0})�msg� socket_err�format)r r r r r r �__init__p s zProxyError.__init__c C s | j S )N)r )r r r r �__str__w s zProxyError.__str__)N)�__name__� __module__� __qualname__�__doc__r" r# r r r r r n s r c @ s e Zd ZdS )�GeneralProxyErrorN)r$ r% r& r r r r r( { s r( c @ s e Zd ZdS )�ProxyConnectionErrorN)r$ r% r& r r r r r) s r) c @ s e Zd ZdS )�SOCKS5AuthErrorN)r$ r% r& r r r r r* � s r* c @ s e Zd ZdS )� SOCKS5ErrorN)r$ r% r& r r r r r+ � s r+ c @ s e Zd ZdS )� SOCKS4ErrorN)r$ r% r& r r r r r, � s r, c @ s e Zd ZdS )� HTTPErrorN)r$ r% r& r r r r r- � s r- zRequest rejected or failedzLRequest rejected because SOCKS server cannot connect to identd on the clientzPRequest rejected because the client program and identd report different user-ids)�[ �\ �] z General SOCKS server failurez!Connection not allowed by rulesetzNetwork unreachablezHost unreachablezConnection refusedz TTL expiredz(Command not supported, or protocol errorzAddress type not supported)r r r � � � � � i8 i� Tc C s. | ||||r|j � nd|r"|j � ndft_dS )z�Sets a default proxy.

Three types are supported: PROXY_TYPE_SOCKS4 (including socks4a), PROXY_TYPE_SOCKS5 and PROXY_TYPE_HTTP addr - The address of the server (IP or DNS). port - The port of the server. Defaults to 1080 for SOCKS servers and 8080 for HTTP proxy servers. rdns - Should DNS queries be performed on the remote side (rather than the local side). The default is True. Note: This has no effect with SOCKS4 servers. username - Username to authenticate with to the server. The default is no authentication. password - Password to authenticate with to the server. Only relevant when username is also provided.N)r6 rt )r r9 r: r; r< r= r> r r r rP a s zsocksocket.set_proxyc O s" d|kr|j d�|d< | j||�S )Nr@ r9 )rA rP )r r r r r r �setproxyv s zsocksocket.setproxyc s� | j \}}}}}}| s$| jtjkr6tj| f|�|�S | jrHtjtd��|t kr`d} tjt | ��t t | �j||� | j � \} } d| f} t� | _| j� } | jj| � d}| j| j|| �\} }| \}} |\} } t t | �j|| f� t t | �j| j� d| _dS ) zVImplements proxy connection for UDP sockets.
