Q: What should I do if I cannot connect to a device through Mavis?
A: Please follow the steps below to troubleshoot:
1. Verify Username and Password
Check if the username and password match the device’s configuration requirements.
If uncertain, contact the device administrator to verify credentials.
Note: For cloud machines, the default SSH login may require an SSH key instead of a username/password. Ensure the correct SSH key is provided.
Run the following command on the device to check if password authentication is supported:
sshd -T | grep passwordauthentication
If the output shows
"no", password login is not supported.
2. Verify Device Access Permissions (Policy)
Ensure the device is properly configured to allow the Mavis Server’s IP address.
Check firewall rules on the device to ensure connections from the Mavis Server are not blocked.
3. Test Network Connectivity to the Device
On the Mavis machine, run the following command to check if the device port is reachable:
telnet <裝置IP> <SSH端口>
Default SSH port: 22
For other protocols (e.g., RDP), verify the corresponding port (default RDP port: 3389).
If the connection fails, check the network connectivity between the device and the Mavis Server (e.g., firewall issues).
4. Verify SSH Service on the Device
Ensure the SSH service is enabled and running, and confirm the correct SSH port.
For devices supporting RDP or other protocols, make sure those services are running properly.
5. Check Device IP Address
Make sure the IP address configured in Mavis matches the actual device IP.
6. Check Mavis Connection Settings
In Mavis, review the device configuration to ensure the protocol, port, and authentication method are correct.
Following these steps should help you identify and resolve the connection issue.
