Method | serviceStarted | called when the service is active on the transport. |
Method | serviceStopped | Called when the connection is stopped. |
Method | requestRemoteForwarding | Undocumented |
Method | cancelRemoteForwarding | Undocumented |
Method | channel_forwarded_tcpip | Undocumented |
Method | channelClosed | No summary |
Method | _cbRemoteForwarding | Undocumented |
Method | _ebRemoteForwarding | Undocumented |
Inherited from SSHConnection:
Instance Variable | localChannelID | the next number to use as a local channel ID. (type: int ) |
Instance Variable | channels | a dict
mapping a local channel ID to SSHChannel subclasses. (type: dict ) |
Instance Variable | localToRemoteChannel | a dict
mapping a local channel ID to a remote channel ID. (type: dict ) |
Instance Variable | channelsToRemoteChannel | a dict
mapping a SSHChannel subclass to remote channel ID. (type: dict ) |
Instance Variable | deferreds | a dict
mapping a local channel ID to a list of Deferreds
for outstanding channel requests. Also, the 'global' key stores the
list of pending global request Deferred s. |
Method | __init__ | Undocumented |
Method | ssh_GLOBAL_REQUEST | No summary |
Method | ssh_REQUEST_SUCCESS | Our global request succeeded. Get the appropriate Deferred and call it back with the packet we received. |
Method | ssh_REQUEST_FAILURE | Our global request failed. Get the appropriate Deferred and errback it with the packet we received. |
Method | ssh_CHANNEL_OPEN | No summary |
Method | ssh_CHANNEL_OPEN_CONFIRMATION | No summary |
Method | ssh_CHANNEL_OPEN_FAILURE | No summary |
Method | ssh_CHANNEL_WINDOW_ADJUST | The other side is adding bytes to its window. Payload:: uint32 local channel number uint32 bytes to add |
Method | ssh_CHANNEL_DATA | The other side is sending us data. Payload:: uint32 local channel number string data |
Method | ssh_CHANNEL_EXTENDED_DATA | No summary |
Method | ssh_CHANNEL_EOF | The other side is not sending any more data. Payload:: uint32 local channel number |
Method | ssh_CHANNEL_CLOSE | The other side is closing its end; it does not want to receive any more data. Payload:: uint32 local channel number |
Method | ssh_CHANNEL_REQUEST | No summary |
Method | ssh_CHANNEL_SUCCESS | Our channel request to the other side succeeded. Payload:: uint32 local channel number |
Method | ssh_CHANNEL_FAILURE | Our channel request to the other side failed. Payload:: uint32 local channel number |
Method | sendGlobalRequest | Send a global request for this connection. Current this is only used for remote->local TCP forwarding. |
Method | openChannel | Open a new channel on this connection. |
Method | sendRequest | Send a request to a channel. |
Method | adjustWindow | Tell the other side that we will receive more data. This should not normally need to be called as it is managed automatically. |
Method | sendData | Send data to a channel. This should not normally be used: instead use channel.write(data) as it manages the window automatically. |
Method | sendExtendedData | Send extended data to a channel. This should not normally be used: instead use channel.writeExtendedData(data, dataType) as it manages the window automatically. |
Method | sendEOF | Send an EOF (End of File) for a channel. |
Method | sendClose | Close a channel. |
Method | getChannel | No summary |
Method | gotGlobalRequest | No summary |
Method | _cleanupGlobalDeferreds | All pending requests that have returned a deferred must be errbacked when this service is stopped, otherwise they might be left uncalled and uncallable. |
Method | _cbChannelRequest | Called back if the other side wanted a reply to a channel request. If
the result is true, send a MSG_CHANNEL_SUCCESS. Otherwise, raise a
error.ConchError |
Method | _ebChannelRequest | Called if the other wisde wanted a reply to the channel requeset and the channel request failed. |
Inherited from SSHService (via SSHConnection):
Method | logPrefix | Override this method to insert custom logging behavior. Its return value will be inserted in front of every line. It may be called more times than the number of output lines. |
Method | packetReceived | called when we receive a packet on the transport |
Called when a channel is closed. It clears the local state related to
the channel, and calls channel.closed(). MAKE SURE YOU CALL THIS METHOD,
even if you subclass SSHConnection
.
If you don't, things will break mysteriously.
