I am somewhat new to computer networking and I created a little project where I have two computers connected to an Ethernet switch, forming a small network. Computer server
(192.168.1.1
) has a mail-server program installed on it (communigate server) and the other computer client
(192.168.1.2
) tries to access mails via an https interface. (I verified both PCs can ping each other).
On client
, I am logging in and out of the web interface while recording traffic on both PCs via wireshark.
What I noticed is that server
does not seem to receive any packets at all from client
. (No packets from 192.168.1.2
)
On the client
machine, I do find lots of TCP packets, but they all have the address 127.0.0.1
(both as source and destination) and there are no packets from 192.168.1.1
When I repeat this experiment with the server
ethernet cable disconnected, client
is unable to access the web-interface, so I assume there should be some sort of connection between the two?
Does anyone understand why WireShark does not record any packets from client
to server
?
