The telnetlib module provides a Telnet class
that implements the Telnet protocol. See RFC 854 for details about the protocol. In
addition, it provides symbolic constants for the protocol characters (see below), and for the
telnet options. The symbolic names of the telnet options follow the definitions in
with the leading
TELOPT_ removed. For symbolic names of options which are
traditionally not included in
arpa/telnet.h, see the module source itself.
The symbolic constants for the telnet commands are: IAC, DONT, DO, WONT, WILL, SE (Subnegotiation
End), NOP (No Operation), DM (Data Mark), BRK (Break), IP (Interrupt process), AO (Abort
output), AYT (Are You There), EC (Erase Character), EL (Erase Line), GA (Go Ahead), SB (Subnegotiation
- Telnet represents a connection to a Telnet server. The instance
is initially not connected by default; the open() method must be
used to establish a connection. Alternatively, the host name and optional port number can
be passed to the constructor, to, in which case the connection to the server will be
established before the constructor returns.
Do not reopen an already connected instance.
This class has many read_*() methods. Note that some of them
raise EOFError when the end of the connection is read, because
they can return an empty string for other reasons. See the individual descriptions below.
