If you are experiencing Test Connection failures for an asset that uses SSL, these are some possible causes:
Both the Safeguard for Privileged Passwords 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, Safeguard for Privileged Passwords 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 Safeguard for Privileged Passwords 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 Safeguard for Privileged Passwords to the list of ciphers.
Safeguard for Privileged Passwords supports these ciphers:
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.
Safeguard for Privileged Passwords does not manage passwords for accounts on domain controllers; Safeguard for Privileged Passwords manages passwords for accounts on a domain controller through a directory that hosts the domain controller. For more information, see Adding an account.
If you are having system connectivity issues, here are some things to consider:
- Are there security rules on the network (such as firewalls or routers) that might be preventing this traffic?
- Is traffic from Safeguard for Privileged Passwords routable to the network address of the managed system?
- Are there any problems with cables, hubs, or switches, and so forth?
You could be experiencing network issues like these:
- Network outage
- Router misconfiguration
- Unplugged wire
- Switch not working
