Hi, I'm not sure if this a configuration issue or could this be a general problem with the 'Diffie-Hellman Group Exchange Request' not being processed properly by OpenBSD.
Problem: OpenBSD SSH server isn't responding to the 'Diffie-Hellman Group Exchange Request' with 'Diffie-Hellman Group Exchange Group'. Server is sending a FIN ACK instead. Same key exchange worked when connecting with the same client and client software, same network, to a commercial product based on FreeBSD (Juniper JUNOS). SSH server then responds with 'Diffie-Hellman Group Exchange Group' which means keys can be exchanged and connection can be established, data transmited, all fine. However, client and client software tested and it works, but again not with OpenBSD as server. All ok from the client site. Client Software: Sshfs Manager 0.0.1.5 (Windows 7 Enterprise) Server: OpenBSD 5.9 Packet capture of issue attached where OpenBSD is acting as the SSH server. Server IP 10.10.1.111 Client IP 10.10.1.166 I've also attached a packet capture where everything is working but no OpenBSD involved (see packet number 12), for comparison. Server IP 10.10.1.210 Client IP 10.10.1.199 The packet captures are pretty small, so please have a look. However, this is not about getting something working on a Windows machine! ;) Answers, comments, ideas much apprechiated, Dennis [demime 1.01d removed an attachment of type application/octet-stream] [demime 1.01d removed an attachment of type application/octet-stream]
