Troubleshooting¶

This page contains hints for troubleshooting Greenbone Community Container specific issues.

Facing an issue with the Greenbone Community Containers¶

If you have an issue with the Greenbone Community Containers because something doesn’t work as expected and/or you are getting an error in the web UI it is necessary to check the log output to get some technical hints about the issue.

To inspect the logs you can use the docker compose logs command. For displaying the complete log output you can run

Display all logs¶

docker compose -f $DOWNLOAD_DIR/docker-compose.yml -p greenbone-community-edition \
    logs

To follow the current log output to display log messages as they occur use the following command

Follow current log output¶

docker compose -f $DOWNLOAD_DIR/docker-compose.yml -p greenbone-community-edition \
    logs -f

It’s also possible to just display the logs of a specific container by using docker compose logs <service> where service is the name of the container within the docker compose file.

Follow the log messages of the gvmd container only¶

docker compose -f $DOWNLOAD_DIR/docker-compose.yml -p greenbone-community-edition \
    logs -f gvmd

Additionally it is possible to bypass the docker compose log command and access the log files directly. For example run the following command to display the content of the OpenVAS scanner log file via cat

Print messages from /var/log/gvm/openvas.log¶

docker compose -f $DOWNLOAD_DIR/docker-compose.yml -p greenbone-community-edition \
    exec ospd-openvas cat /var/log/gvm/openvas.log

Afterwards using the collected error messages in the search of our Community Forum may bring up possible results to resolve the issue already.

If no fitting results can be found feel free to create a new topic the Community Containers category in our Community Forum.

VTs are up-to-date but not visible on the web interface¶

It may be possible, especially for the initial synchronization, that the scanner does not notice new VT files have arrived. Therefore, it is best to restart the scanner.

Restart the scanner to ensure that new VTs are loaded¶

docker compose -f $DOWNLOAD_DIR/docker-compose.yml -p greenbone-community-edition \
    restart ospd-openvas

Port list, scan configurations, report formats are up-to-date but not visible on the web interface¶

If port lists, scan configurations, or report formats are missing on the web interface, you may run:

Forcing reload of report formats, scan configs and port lists¶

docker compose -f $DOWNLOAD_DIR/docker-compose.yml -p greenbone-community-edition \
    exec -u gvmd gvmd gvmd --rebuild-gvmd-data=all

to force gvmd to reload the data from the file system.

Errors while starting `pg-gvm` container¶

While starting up the pg-gvm container, some errors are displayed. For example createuser: error: creation of new role failed: ERROR: role "gvmd" already exists or ERROR: extension "uuid-ossp" already exists.

The code behind these errors tries to set up the database. If the database is already initialized, all tables, users, permissions and extensions exist, errors are raised. At the moment, it is not possible to silence these errors but they can be ignored safely.

`osp_scanner_feed_version: failed to connect to /run/ospd/ospd-openvas.sock`¶

If the gvmd log contains this error, gvmd is not able to connect to the ospd-openvas scanner. Most likely ospd-openvas is not running. Try to restart the corresponding container with:

Restarting the ospd-openvas scanner¶

docker compose -f $DOWNLOAD_DIR/docker-compose.yml -p greenbone-community-edition \
    restart ospd-openvas

If you still get errors, you need to take a look at the ospd-openvas logs.

Showing log message of the ospd-openvas scanner¶

docker compose -f $DOWNLOAD_DIR/docker-compose.yml -p greenbone-community-edition \
    log -f ospd-openvas

Cannot log in to the web interface: Greenbone Vulnerability Manager service is not responding¶

If it is not possible to log in to the web interface and the following error message is shown

and/or the logs contain a Failed to connect to server at /run/gvmd/gvmd.sock: Connection refused message, the gvmd container must be restarted. It is very likely it had some issues accessing the PostgreSQL database.

Restarting gvmd¶

docker compose -f $DOWNLOAD_DIR/docker-compose.yml -p greenbone-community-edition \
    restart gvmd

Redis server keeps restarting `rm: cannot remove ‘/run/redis/redis.sock’: Permission denied`¶

Under some circumstances the Unix Domain Socket of the Redis server has got wrong permissions. To fix this issue it is required to shutdown the redis-server and ospd-openvas containers and remove the redis_socket_vol docker volume. The volume can be removed safely because it gets recreated on the next startup.

Recreating the Redis server socket volume¶

docker compose -f $DOWNLOAD_DIR/docker-compose.yml -p greenbone-community-edition \
    rm -s -f redis-server ospd-openvas
docker volume rm greenbone-community-edition_redis_socket_vol
docker compose -f $DOWNLOAD_DIR/docker-compose.yml -p greenbone-community-edition \
    up -d
