NETSTAT displaying weird connection in the FROM location !!

[furquan]

Hello Everyone,

I at times have a some load issues on the server and it generally happens due to huge number of concurrent connections to my server.

I run this command to check the IP's connecting to my server :-

netstat -anp |grep 'tcp\|udp' | awk '{print $5}' | cut -d: -f1 | sort | uniq -c | sort -n

But at the end of the results, i see many a times connections like these :-

20
48 0.0.0.0

They show the number of connections but NOT from any location, I am worried what is it ?

Can any one assist me with this ?

Thank you for your time.

You may try the following command.

netstat -ntu | awk '{print $5}' | cut -d: -f1 | sort | uniq -c | sort -n

Cheers!!!
