1. How do I change the default E-mail address of the system’s administrator?
To change the default E-mail address of the system’s administrator, you have to change it directly in the database.
2. What is the difference between Docker-based and VMware-based antivirus?
Docker-based antivirus have advantages over VMware antivirus, including:
1- Their scans are faster.
2- They get updated by Cyberno, and there would not be any problems in the system after updating the antivirus.
3- They consume fewer processing resources. The antivirus that cannot be run on Docker, get installed as virtual machines on VMware ESXi and communicate remotely with the main server of the MultiScanner system. It is obvious that the scan would be slower because of the distance between the virtual machine and the system’s main server.
3. What to do when the user interface failed to run?
If you faced any error during running of the user interface, first, check has the Docker service been run on the server or not. To do so, run the following command:
sudo docker ps -a
Second, check the status of the MultiScanner service using the following command:sudo systemctl status multiscanner.service
If the service is not running, use the following command to run it again:sudo systemctl restart multiscanner.service
Third, check if any errors happened or not by running the command below:sudo journalctl -u multiscanner.service -b -f
4. What to do if a Docker-based antivirus does not work properly?
If any antivirus in the MultiScanner does not work properly, you have to check if it has a problem or not. To do so, first go the API’s document part (Docker section, "Start antivirus docker" sub-section) and start the antivirus. In the name section, insert the name of the antivirus, all in lowercase (like fsecure).
After that, check if the antivirus runs properly or if it encounters an error again. To do so, run the following command (replace “av_name” with the antivirus’s name):
sudo docker logs -f av_name
You also need to check if the antivirus can detect the tests malwares properly or not. To run the test manually, run the following command:
sudo docker exec -it av_name python3 /root/test.py
There should be at least one and at most 17 detected malware (running the test requires an internet connection).
If the antivirus still does not work properly, first, stop it from running through the API and update it again. It is recommended to remove the Docker file of the antivirus from the below path before initiating the updating process:
/opt/manager/Dockers
If you still have any problems regarding this issue, do not hesitate to call Cyberno’s technical support.
5. What to do if a VMware-based antivirus does not work properly?
First, you need to check if the virtual machine is running properly or not. You also need to see if the antivirus is running and is configured in accordance with the documents’ settings or not. The other thing that should be investigated is whether the Wrapper software has been running on the virtual machine or not. Be sure that the firewalls have not blocked the connection between the antivirus virtual machine and the MultiScanner's main server.
If you have any problem concerning this issue, please call Cyberno’s technical support.
6. What to do if the operation during the initiating of the scanning process takes too long?
As initiating the scanning process requires counting files, checking their types, and extracting their contents in it is needed, it could takes a while. This happens, especially in older and slower servers or when there are too many files to scan.
If the scanning process did not initiate even after a long time, you can manually initiate the process using the API. To do so, first you need to open the API’s document section. Second, use the "initial tasks of the remote scanning operation" function.
Wait for a few minutes until the running of the API finishes, and then check the output to see if any errors have occurred or not. You also need to investigate the logs of the MultiScanner service, using the command below:
sudo journalctl -u multiscanner.service -b –f
