I wanna capture telnet packet with such a simple client-server topology.
There is no configuration under Services
on the server-side.
I tried to telnet to the server on Command Prompt
with:
C:\>telnet 192.168.1.80
Trying 192.168.1.80 ...
% Connection refused by remote host
I learned from serval guides that it is able to capture telnet packets by adding a switch or router.
My question is: is it possible to make a telnet connection on such a scenario: client -- server
?

The answer is yes on a normal scenario but not in Packet tracer.
To be able to Jump to a Server using Telnet or SSH you should enable that telnet or SSH service on both client and server side. Packet tracer doesn't have that features on PCs and Servers i think...
To capture Telnet packets you could instead use a Router and as you said, a Switch to mirror ports.
Something like this
Router Config
Switch Config
On a real life scenario the Sniffer would be replaced by a PC or Laptop, and we would use a packet capture program like Wireshark.
I hope this is helpful, Regards!
