-
handleMSG_CHANNEL_CLOSE(
MSG_CHANNEL_CLOSE msg) → void - Upon receiving this message, a party MUST send back an SSH_MSG_CHANNEL_CLOSE unless it has already sent this message for the channel.
-
handleMSG_CHANNEL_DATA(
MSG_CHANNEL_DATA msg) → void - Data transfer is done with messages of the type SSH_MSG_CHANNEL_DATA.
-
handleMSG_CHANNEL_EOF(
MSG_CHANNEL_EOF msg) → void - No explicit response is sent to this message. However, the application may send EOF to whatever is at the other end of the channel.
