Hi,

While I was working, the follwing message flud the screen.

Aug 13 23:32:28 www /kernel: Limiting closed port RST response from 213 
to 200 packets per second

The /var/log/apache_ssl_engine.log started
to grow with similar messages:

[13/Aug/2004 23:43:49 66440] [error] SSL handshake failed (server 
www.beco.hu:443, client 217.102.90.240) (OpenSSL library error follows)

routines:GET_CLIENT_FINISHED:connection id is different

I don't have the output of the following command:
netstat -anfinet
but it showed a lot of connection from the above IP. on port 443.

Has any other effect of such attacks beside
filling the /var/log?

bye
