older connections with netstat
 

Hello Guys,

is there a possibility to find out and show (list) the older network connections on the certain port (e.g. 23) with netstat command?

If not, is there any other command for it?

I need to check the last two days. Where can i find them?

Thx in advance!

Not sure about this possibility but if you suspect the "thing" you are looking for to occur again you can run tcpdump on the system to capture its network communication. Only some particular ports for example so the output is not so big.
