Hi all,

I'm trying to use the SSH connection node toward a remote linux server running Debian Jessie. when I test the connection I receive the following error: "Connection to ssh://name@server:22 failed Algorithm negotiation fail".

Do anyone know how to fix this issue?

Thanks,

Matteo

The JSch library we are currently using supports the following algorithms:

  • Key exchange: diffie-hellman-group-exchange-sha1, diffie-hellman-group1-sha1
  • Cipher: blowfish-cbc,3des-cbc,aes128-cbc,aes192-cbc,aes256-cbc,3des-ctr,aes128-ctr,aes192-ctr,aes256-ctc,arcfour,arcfour128,arcfour256
  • MAC: hmac-md5,hmac-md5-96,hmac-sha1,hmac-sha1-96

Make sure that your server also supports at least one combination.

Has there been an update to the JSch library? I have been using the SSH Connection node for a while and am recently getting the error "Execute failed: Session.connect: java.io.IOException: End of IO Stream Read"

No, there has not been an update since 2015. Also your error message indicates a network problem.
