Class NetProcess

source code

Class NetProcess represents one network connection. Most of the properties are read from /proc/net/{tcp,udp,raw} lines. The class uses dictionary-like mapping.

The fields we remember about a process are described in NetProcess.keys. Mapping of someof them to fields in /proc/net file are in NetProcess.keys. In order to save some space, TCP states are stored in NetProcess.states and every process has only an integer pointing into this list.

Instance Methods [hide private]
 
__eq__(self, other)
Comparison operaton.		 source code
 
__neq__(self, other)
Negative comparison operaton Returns True if the object holds the same data as the other object.		 source code
 
__repr__(self)
Prints out a human readable representation of the structure that can be easily used to recreate the same object		 source code
 
__str__(self)
Returns human-readable representation of the object		 source code
 
__resolve_ip(self, address)
Tries to resolve a hostname for a given IP.		 source code
 
__resolve_portnum(self, portnum)
Tries to resolve a service name for a given portnum.		 source code
 
__check_key(self, key)
The strategy is: if we are asked for a key we should not know, raise exception.		 source code
 
__getitem__(self, key)
Return item or N/A if not set.		 source code
 
__setitem__(self, key, value)
Adjust value of a key.		 source code
 
__init__(self, line)
Parses given line and stores in an internal dictionary (see UserDict)		 source code
 
__parse_address(self, addr)
Adresses in the /proc/net/{tcp,udp} file are in reverse byte-order.		 source code
 
__parse_line(self, line)
Splits fields of a given line and stores them in self-dictionary (see UserDict).		 source code

Method Details [hide private]

__eq__(self, other)
(Equality operator)

source code 
Comparison operaton. Returns True if the object holds the same data as the other object.

__repr__(self)
(Representation operator)

source code 
Prints out a human readable representation of the structure that can be easily used to recreate the same object
Overrides: UserDict.UserDict.__repr__

__resolve_ip(self, address)

source code 
Tries to resolve a hostname for a given IP. If not successfull, returns the IP adress back

__resolve_portnum(self, portnum)

source code 
Tries to resolve a service name for a given portnum. If not successfull, returns the port number back

__check_key(self, key)

source code 
The strategy is: if we are asked for a key we should not know, raise exception. If we are asked for a key we should know, but for some reason we don't (such as could not find icon, or could not resolve pid for a root program) we return N/A

__getitem__(self, key)
(Indexing operator)

source code 
Return item or N/A if not set. Raises KeyError if the key is not in NetProcess.keys
Overrides: UserDict.UserDict.__getitem__

__setitem__(self, key, value)
(Index assignment operator)

source code 
Adjust value of a key. Raises KeyError if the key is not in NetProcess.keys.
Overrides: UserDict.UserDict.__setitem__

__init__(self, line)
(Constructor)

source code 
Parses given line and stores in an internal dictionary (see UserDict)
Overrides: UserDict.UserDict.__init__

__parse_address(self, addr)

source code 
Adresses in the /proc/net/{tcp,udp} file are in reverse byte-order. This file converts it to human-readable notation and returns a tuple of: ('address', port)

__parse_line(self, line)

source code 
Splits fields of a given line and stores them in self-dictionary (see UserDict). Raises IndexError if the line does not have correct number of fields or ValueError if a field does not contain the info it should.
