[Info-vax] SSH problem after upgrade on remote system

[Phillip Helbig undress to reply]

I use ssh and scp from my VMS system to access a remote linux box (which
I don't manage).  It has worked fine for years.  After an upgrade on
the remote box, I get from ssh:

warning: Authentication failed.
Disconnected; key exchange or algorithm negotiation failed (Algorithm
negotiation failed.).

and from scp:

tcpip$ssh_scp2.exe: warning: ssh2 client failed to authenticate. (or you
have too old ssh2 installed, check with ssh2 "-V")
warning: Authentication failed.
Disconnected; key exchange or algorithm negotiation failed (Algorithm
negotiation failed.).

tcpip$ssh_scp2.exe: warning: child process (/sys$system/tcpip$ssh_ssh2)
exited with code 131.


%TCPIP-E-SSH_FC_ERROR, error in ssh file transfer operation

If the problem is that the version is too old, can I get a newer one?  I
also get it on my 8.4 node with (presumably) the latest version of ssh,
though the version numbers look the same.

Is it possible to enable something on the remote node?
