howto track DDoS attack on a linux server
 

hello
I wanted to know how can I track a Dos and DDoS attack on a server . Does linux have any goiod known command line utilities and log files to us e in this way?

It depends on how the DDoS is happening, IMO.

The netstat command should help in diagnosing such issues, along with 'ps' or top (for checking system resource utilization [cpu/mem] and the amount of resources a process or processes may be utilizing). Service logs may also help some.

Note that there is no "magic sauce" for remediating DDoS (ie, there's no solution unless you work at a very large company that has its own backbone).
