A wrapper for telnetlib.Telnet() that handles SSL/TLS, with optional TELNET negotiated TLS. This can be used to connect to TELNETS and SSLTELNET servers, as well as various MUD/MUCK/MUSH chat servers.
The API for SslTelnet is just like that for the standard python library telnetlib, with the addition of a few arguments to the Telnet() initializer.
- ssltelnet.SslTelnet()
Called just like telnetlib.Telnet(), with these extra optional arguments:
- force_ssl
If True, force SSL negotiation as soon as connected. Defaults to True.
- telnet_tls
If true, allow TELNET TLS negotiation after non-ssl connection. Defaults to True.
You can also pass args that ssl.wrap_socket() would expect.
If force_ssl is True, plaintext connections aren't allowed. If force_ssl is False, and telnet_tls is True, the connection will be plaintext until the server negotiates TLS, at which time the connection will be secured. If both are False, the connection will be plaintext.
import ssltelnet
s = ssltelnet.SslTelnet(force_ssl=False, host='foobar.com', port=23)
print(s.read_until(b'\n', 10))
s.close()
