Since i installed directadmin a few days ago, at the same time i received brutforce attacks and it keeps going on until now. there are like thousands of brutforces attacks daily. what is this and how can i prevent it?
 
thanks so much . but does that mean that everyone has / had same issue?
 
Brutefroce attacks are attempt to log into your server, everyone does have them, is at you to keep your server secure with nice password and to use different ports beside the standard one (not mandatory if you use strong password and implement security system to ban the IP of attackers).

Thank you for your advice., but changing the port did not really help. i changed the port to something random, not even an easy number but it didint really help, the brutforcing keeps going on. i just logges in to my interface with the new port and i saw last attack a few minutes ago. it happens every 15 minutes.
 
Are BruteForce notice related to DA (i did presume yes but actually you didnt specify that) or other services?

If other services, what services? It may be SSH,SMTP,IMAP,POP and so on.

The only port you may change for those services is the SSH one, and you need to change /etc/ssh/sshd_config to acchieve that (and restart sshd after that), also you should not permit direct root login, and use a second account for ssh login with permission to use "su" command.

The bruteforce notify, is just a notify of an attempt, is not an hack, is an attempt.

As already sayd, you should also consider to implement CSF with BFM to ban those IP who try to bruteforce your server.

If your not able to do that or if your knoledge on Linux System is not that strong, me and other guys on this forum offer sysadmin services as paid service.

Feel free to contact me or anyone you desire by PM for a quote.

Regards
 
Can someone tell me where all the blocked attempts are stored? i cant find any blacklists in the folders of da. i am using the default port 2222 and activated the "Blacklist IPs for excessive DA login attempts" and the " Parse service logs for brute force attacks". thanks.
