Test Connection failures
The most common causes of failure in SPP are either connectivity issues between the appliance and the managed system, or problems with service accounts.For more information, see Connectivity failures..
Disabling User Account Control (UAC) Admin Approval Mode on a remote host can also resolve Test Connection failures. For more information, see Change password or SSH key fails..
If you have entered values for Specify Domain Controllers and if SPP does not find a domain controller in the list, the test connection fails and an error is returned.
The following topics explain some possible reasons that Test Connection could fail.
Test Connection failures on archive server
There could multiple reasons why you receive an Unexpected copying error... when attempting to run Test Connection on an existing archive server.
When you run Test Connection, SPP adds a file named Safeguard_Test_Connection.txt to the Storage Path location of the archive server owned by the Account Name you entered when you created the archive server. To run Test Connection on an existing archive server with a new account name, you must first delete the existing Safeguard_Test_Connection.txt file.
Certificate issue
If you are experiencing Test Connection failures for an asset that uses SSL, these are some possible causes:
Cipher support
Both the SPP client and the SSH server must support the same cipher. If you run Test Connection against an asset that uses SSH and there is no cipher supported by both the client and the server, SPP displays an error message that says, Connecting to asset XXXXXXXXXXXXXXXXXX failed (There is no cipher supported by both: client and server). This means that during the setup of the asset connection, the SPP client and the SSH server did not have matching ciphers for message encryption. In this case, you must modify the SSH server's configuration by adding at least one cipher supported by SPP to the list of ciphers.
SPP supports these ciphers:
- 3des
- 3des-ctr
- aes128
- aes128-ctr
- aes192
- aes192-ctr
- aes256
- aes256-ctr
- arcfour
- arcfour128
- arcfour256
- blowfish
- blowfish-ctr
- cast128
- cast128-ctr
- des
- idea
- idea-ctr
- none
- serpent128
- serpent128-ctr
- serpent192
- serpent192-ctr
- serpent256
- serpent256-ctr
- twofish128
- twofish128-ctr
- twofish192
- twofish192-ctr
- twofish256
- twofish256-ctr
For example, if using an OpenSSH server with a default list of ciphers, you must add one or more of these ciphers in the OpenSSH's sshd_config file, and then restart the SSH server. For more information about OpenSSH ciphers, see http://www.openbsd.org/cgi-bin/man.cgi/OpenBSD-current/man5/sshd_config.5?query=sshd_config&sec=5.
