clean up server interface; no longer need to subclass Channel
- export AUTH_*, OPEN_FAILED_*, and the new OPEN_SUCCEEDED into the paramiko
namespace instead of making people dig into paramiko.Transport.AUTH_* etc.
- move all of the check_* methods from Channel to ServerInterface so apps
don't need to subclass Channel anymore just to run an ssh server
- ServerInterface.check_channel_request() returns an error code now, not a
new Channel object
- fix demo_server.py to follow all these changes
- fix a bunch of places where i used "string" in docstrings but meant "str"
- added Channel.get_id()
new ServerInterface class, outbound rekey works, etc.
a bunch of changes that i'm too lazy to split out into individual patches:
* all the server overrides from transport.py have been moved into a separate
class ServerInterface, so server code doesn't have to subclass the whole
paramiko library
* updated demo_server to subclass ServerInterface
* when re-keying during a session, block other messages until the new keys
are activated (openssh doensn't like any other traffic during a rekey)
* re-key when outbound limits are tripped too (was only counting inbound
traffic)
* don't log scary things on EOF
support py22, more or less
add roger binns' patches for supporting python 2.2. i hedged a bit on the
logging stuff and just added some trickery to let logging be stubbed out for
python 2.2. this changed a lot of import statements but i managed to avoid
hacking at any of the existing logging.
socket timeouts are required for the threads to notice when they've been
deactivated. worked around it by using the 'select' module on py22.
also fixed the sftp unit tests to cope with a password-protected private key.
more docs, and password-protected key files can now be read
lots more documentation, some of it moved out of the README file, which is
now much smaller and less rambling.
repr(Transport) now reports the number of bits used in the cipher.
cleaned up BER to use util functions, and throw a proper exception (the new
BERException) on error. it doesn't ever have to be a full BER decoder, but
it can at least comb its hair and tuck in its shirt.
lots of stuff added to PKey.read_private_key_file so it can try to decode
password-protected key files. right now it only understands "DES-EDE3-CBC"
format, but this is the only format i've seen openssh make so far. if the
key is password-protected, but no password was given, a new exception
(PasswordRequiredException) is raised so an outer layer can ask for a password
and try again.
added public-key support to server mode, more docs
added public-key support to server mode (it can now verify a client signature)
and added a demo of that to the demo_server.py script (user_rsa_key). in the
process, cleaned up the API of PKey so that now it only has to know about
signing and verifying ssh2 blobs, and can be hashed and compared with other
keys (comparing & hashing only the public parts of the key). keys can also
be created from strings now too.
some more documentation and hiding private methods.
lots more documentation, and added Transport.connect()
renamed demo_host_key to demo_rsa_key. moved changelog to a separate file,
and indicated that future changelog entries should be fetched from tla.
tried to clean up "__all__" in a way that makes epydoc still work.
added lots more documentation, and renamed many methods and vars to hide
them as private non-exported API.
Transport's ModulusPack is now a static member, so it only has to be loaded
once, and can then be used by any future Transport object.
added Transport.connect(), which tries to wrap all the SSH2 negotiation and
authentication into one method. you should be able to create a Transport,
call connect(), and then create channels.
hook up server-side kex-gex; add more documentation
group-exchange kex should work now on the server side. it will only be
advertised if a "moduli" file has been loaded (see the -gasp- docs) so we
don't spend hours (literally. hours.) computing primes. some of the logic
was previously wrong, too, since it had never been tested.
fixed repr() string for Transport/BaseTransport. moved is_authenticated to
Transport where it belongs.
added lots of documentation (but still only about 10% documented). lots of
methods were made private finally.
fix dss key signing
(expanded on a patch from fred gansevles)
add a demo dss key for server mode, and fix some bugs that had caused the dss
signing stuff to never work before. the demo_server is a bit more verbose
now, too. both key types (RSAKey & DSSKey) now have a function to return the
fingerprint of the key, and both versions of read_private_key_file() now raise
exceptions on failure, instead of just silently setting "valid" to false.
cleaned up server code, renamed some files & classes
renamed demo-server.py and demo-host-key to demo_server.py and
demo_host_key, just to be consistent.
renamed SSHException -> SecshException.
generalized the mechanism where Channel decides whether to allow
different channel requests: 4 of the main ones (pty, window-change,
shell, and subsystem) go through easily override-able methods now.
you could probably make an actual ssh shell server.
gave ChannelFile a repr().
turned off ultra debugging in the demos. demo_server creates a
subclass of Channel to allow pty/shell and sets an event when the
shell request is made, so that it knows when it can start sending
the fake bbs.
renamed to charmander and updated some of the distutils files.
