Hi everyone,

I think I'm under attack I need help please.

Hackers are trying to login to my pbx gateway. I don't know why I viewed the log file to see why my gateway is rebooting himself every few minutes using this command below

tail -f /var/log/messages
authpriv.info dropbear[32417]: Child connection from xx.xx.xx.xx:2xxxx
authpriv.info dropbear[32417]: exit before auth: Disconnect received
auth.warn login[20056]: invalid password for 'UNKNOWN' on 'pts/7'
auth.warn login[20118]: invalid password for 'UNKNOWN' on 'pts/1'
auth.warn login[20582]: invalid password for 'UNKNOWN' on 'pts/4'
auth.warn login[20656]: invalid password for 'UNKNOWN' on 'pts/5'

And I see UNKNOWN user is trying to access.

I did a research about that on Google and I found a solution for that say have close SSH PasswordAuthentication. But I followed the steps to do that an I didn't find the file sshd_config that should be edit In etc/SSH/

Can someone help me please.

a bat file will be better

i did a test but it wont work i cant find the test ip i want it to be in the scope

Hi,

i need a little help its about windows firewall rules and batch file script on windows server 2008

i have created a rule in windows firewall inbound connections to block unwanted ip addresses.

the normal way to block unwanted ip's i open the rule and go to the scope tab and add the ip I want to block.

Is there a way that I can update the rule I created using a batch file and text note? What I mean is updating the scope with new ip’s that will be in the note.

Thank you all for your help
