   3 \A{sshnames} SSH-2 names specified for PuTTY
   4
   5 There are various parts of the SSH-2 protocol where things are specified
   6 using a textual name.  Names ending in \cw{@putty.projects.tartarus.org}
   7 are reserved for allocation by the PuTTY team.  Allocated names are
   8 documented here.

  10 \H{sshnames-channel} Connection protocol channel request names
  11
  12 These names can be sent in a \cw{SSH_MSG_CHANNEL_REQUEST} message.

  16 \dd This is sent by a client to announce that it will not have more than
  17 one channel open at a time in the current connection (that one being
  18 the one the request is sent on).  The intention is that the server,
  19 knowing this, can set the window on that one channel to something very
  20 large, and leave flow control to TCP.  There is no message-specific data.

  22 \dt \cw{winadj@putty.projects.tartarus.org}
  23
  24 \dd PuTTY sends this request along with some
  25 \cw{SSH_MSG_CHANNEL_WINDOW_ADJUST} messages as part of its window-size
  26 tuning.  It can be sent on any type of channel.  There is no
  27 message-specific data. Servers MUST treat it as an unrecognised request
  28 and respond with \cw{SSH_MSG_CHANNEL_FAILURE}.
