  • Question about Kex Algorithms

    From Camila Lui@camila.lui@gmail.com to comp.sys.tandem on Thu Feb 9 10:44:47 2023

    Hello,

    I would like to know if anyone had experienced issues using different Kex algorithms to establish SSH connections.

    Any luck using ecdh-sha2-nistp256 on Nonstop systems? This is one of the "available" Kex that jsch library supports, but no luck so far.

    Thank you

    The HPE NonStop SSH Reference Manual does not list it as one of the supported Kex algorithms. I tried configuring it on my H06.29.00 system and the SSH server would not accept it as a valid choice. If you donrCOt specify anything the server configuration, the default choices are diffie-hellman-group-exchange-sha256 and diffie-hellman-group14-sha1.

    As far as I know, jsch is no longer supported (sadly because losing it causes additional work to convert, but that happens). It has been replaced by Apache MINA in recent ECLIPSE versions.
