The display filter can be changed above the packet list as can be seen in this picture:Ĭapture only traffic to or from IP address 172.18.5.4:Ĭapture traffic to or from a range of IP addresses:Ĭapture traffic from a range of IP addresses:Ĭapture traffic to a range of IP addresses:Ĭapture non-HTTP and non-SMTP traffic on your server (both are equivalent): In the main window, one can find the capture filter just above the interfaces list and in the interfaces dialog. Display filters on the other hand do not have this limitation and you can change them on the fly. The latter are used to hide some packets from the packet list.Ĭapture filters are set before starting a packet capture and cannot be modified during the capture. The former are much more limited and are used to reduce the size of a raw packet capture. If you have 2 devices on the same switch talking to each other you will NOT see the packets, as these packets will not be sent to the main router.Ĭapture filter is not a display filter ( )Ĭapture filters (like tcp port 80) are not to be confused with display filters (like tcp.port = 80).

*Note: Only packets sent through the main router in B34 will be seen.

Please remember to delete unwanted files. Remember every time you perform a capture it will create a file in /tmp/ether*
