SCP identity agent key invalid problem

I am getting below error while coping some files with scp task

2018-03-21 07:19:00,116 INFO [17-BAM::Default Agent::Agent:pool-32-thread-1] [TransportImpl] Client identity string: SSH-2.0-SSHJ_0.21.12018-03-21 07:19:00,182 WARN [17-BAM::Default Agent::Agent:pool-32-thread-1] [IdentificationStringParser] Server identification has bad line ending, was expecting a '\r\n' however got: '2' (hex: 32)2018-03-21 07:19:00,183 WARN [17-BAM::Default Agent::Agent:pool-32-thread-1] [IdentificationStringParser] Will treat the identification of this server 'SSH-2.0-OpenSSH_7.4p1 Debian-10+deb9u2' leniently

This error started getting after changing remote server without changing IP.

Simon says:

On your remote SSH server (the one that is the destination of the copy operation) configuration set the following option:

DebianBanner no

and restart the remote SSH server. This will transform the SSH banner to  SSH-2.0-OpenSSH_7.4p1.

On some other distribution you may have to use instead the option:

VersionAddendum none

in the SSH server configuration on the remote host.

Cheers, Simon out.

Hello Simon, I tried both but not work for me. The result is the same.

Do you get the same error when you execute the scp command from the terminal as the same user outside Bamboo?

If it didn't error out, you may use the script task instead of scp task where you can define your scp command.

I used script instead of scp task. I guess scp task cache the ip addresses or ssh library of java cache the ip address. And the ip changed for same server. The scp task give this error interestingly.
