OpenSSH_6.1p1 sends a SSH packet bigger than 32K
The full SSH_MSG_CHANNEL_DATA packet looks like this: uint32 packet length byte SSH_MSG_CHANNEL_DATA uint32 recipient channel uint32 nr data bytes byte[] data OpenSSH_6.1p1 considers that the 'maximum packet size' from SSH_MSG_CHANNEL_OPEN or SSH_MSG_CHANNEL_OPEN_CONFIRMATION impacts only the 'byte[] data' field and not the entire message (headers included). Section 5.1 from RFC 4254 (which talks about this limitation) leaves room for interpretation when it comes to the 'maximum packet size' because it "specifies the maximum size of an individual...

Security suggestion concering SSH and port forwarding.
Hi, sorry if it is the wrong approuch to suggest improvments to OpenSSH, but here comes my suggestion: I recently stumbled upon the scponly shell which in it's chroot:ed form is an ideal solution when you want to share some files with people you trust more or less. The problem is, if you use the scponlyc as shell, port forwarding is still allowed. This can of course be dissallowed in

Questions about inferred state machines for OpenSSH
Dear all, For my thesis, I've been working on automatic inference of state machines for SSH servers. I ran into a couple of particularities regarding OpenSSH's inferred state machine, and was hoping some of you might be interested. Maybe you can even shed some light on it. Setup: I'm using LearnLib's (Java) version of the L* learning algorithm [1] to come up with sequences of

I'm trying to send data to a server with openssh 7.9p1, but it's hanging somewhere. the client stop at the line : Jul 7 11:52:16 TOTO sshd[19553]: debug3: channel 0: will not send data after close and after 5 minutes the client closes the connection, why ? This is the trace of the server openssh : ( DEBUG3 level) Jul 7 11:52:15 TOTO sshd[31175]: debug3: fd 6 is not O_NONBLOCK Jul
