The channel has a local window which is the maximum amount of data it will receive, and a remote which is the maximum amount of data the remote side will accept. There is also a maximum packet size for any individual data packet going each way. @ivar name: the name of the channel. @type name: L{bytes} @ivar localWindowSize: the maximum size of the local window in bytes. @type localWindowSize: L{int} @ivar localWindowLeft: how many bytes are left in the local window. @type localWindowLeft: L{int} @ivar localMaxPacket: the maximum size of packet we will accept in bytes. @type localMaxPacket: L{int} @ivar remoteWindowLeft: how many bytes are left in the remote window. @type remoteWindowLeft: L{int} @ivar remoteMaxPacket: the maximum size of a packet the remote side will accept in bytes. @type remoteMaxPacket: L{int} @ivar conn: the connection this channel is multiplexed through. @type conn: L{SSHConnection} @ivar data: any data to send to the other side when the channel is requested. @type data: L{bytes} @ivar avatar: an avatar for the logged-in user (if a server channel) @ivar localClosed: True if we aren't accepting more data. @type localClosed: L{bool} @ivar remoteClosed: True if the other side isn't accepting more data. @type remoteClosed: L{bool} NnamecU=(d SUlURUlU=(d SUlX0lX@lSUlXPlX`lXplSUl SUl /Ul SUl SUl SUlSUlg)Niir)localWindowSizelocalWindowLeftlocalMaxPacketremoteWindowLeftremoteMaxPacket areWritingconndataavatar specificDatabufextBufclosing localClosed remoteClosedid)self localWindowr remoteWindowrrrrs ]C:\Users\psant\Downloads\Noiseback\school\venv\Lib\site-packages\twisted/conch/ssh/channel.py__init__SSHChannel.__init__9s +4f#33,5 ,.     r returnc@UR5RS5$)Nascii) __bytes__decoders r!__str__SSHChannel.__str__Ts~~&&w//r cdURnU(dSnSUURUR4-$)z4 Return a byte string representation of the channel sNones)r rr)rr s r!r'SSHChannel.__bytes__Ws<yyD/    ! !3   r c URSL=(a [UR5=(d SnUR(aURRS5nOSnSUSUSURR 53$)Nunknownr&Nonez SSHChannel z (z) on )rstrr r(r logPrefix)rrr s r!r2SSHChannel.logPrefixesiggT!2c$''l @y 9999##G,DDTF"RDdii.A.A.C-DEEr c:URRS5 g)z Called when the channel is opened. specificData is any data that the other side sent us when opening the channel. @type specificData: L{bytes} z channel openN_loginfo)rrs r! channelOpenSSHChannel.channelOpenms ~&r c8URRSUS9 g)z Called when the open failed for some reason. reason.desc is a string descrption, reason.code the SSH error code. @type reason: L{error.ConchError} z(other side refused open reason: {reason})reasonN)r6error)rr;s r! openFailedSSHChannel.openFailedvs CFSr cURU-UlUR(d(UR(dSUlUR5 UR(a$URnSUlUR U5 UR (a0UR n/UlUHup1URX15 M gg)zt Called when bytes are added to the remote window.
