   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.
   9
  10 \H{sshnames-global} Connection protocol global request name
  11
  12 This name can be sent in a \cw{SSH_MSG_GLOBAL_REQUEST} message.
  13
  14 \dt \cw{simple@putty.projects.tartarus.org}
  15
  16 \dd This is sent by a client to announce that it will not have more that
  17 one channel open at a time in the current connection.  The intention
  18 is that the server, knowing this, can set the window on that one
  19 channel to something very large, and leave flow control to TCP.  The
  20 format of the request is:
  21
  22 \lcont{
  23
  24 \c byte      SSH_MSG_GLOBAL_REQUEST
  25 \c uint32    recipient channel
  26 \c string    "simple@putty.projects.tartarus.org"
  27 \c boolean   want reply
  28
  29 }
  30
  31 \H{sshnames-channel} Connection protocol channel request name
  32
  33 This name can be sent in a \cw{SSH_MSG_CHANNEL_REQUEST} message.
  34
  35 \dt \cw{winadj@putty.projects.tartarus.org}
  36
  37 \dd PuTTY sends this request along with some
  38 \cw{SSH_MSG_CHANNEL_WINDOW_ADJUST} messages as part of its window-size
  39 tuning.  It can be sent on any type of channel.  Servers MUST treat it
  40 as an unrecognised request and respond with
  41 \cw{SSH_MSG_CHANNEL_FAILURE}.
  42
  43 \H{sshnames-kex} Key exchange method names
