Hello. Since some weeks i got query logins from unkown ip’s all the time. I guess thats why my server crashing from day to day. After I blacklist thos IP’s via deny list it got silent for some days and then the crashing starting again. Most of thos IP’s come from china.
I see in the logs that its a query request which probably flailed. So my question is how can i deactiavte all query access points, query, ssh query and http query?
If i need this access i can restart the server with turned it on but since nobody use it except for me i dont need it activly running and if i deactivate it i will deny any possible attacker who want to use this access.
