How do I set up my host configuration for GNS3?
I have GNS3 and am just starting out trying to learn a bit about networking. I did the tutorial here: https://docs.gns3.com/1d1huu6z9-wWGD_ipTSQZqy2mpaxiqzymu-YQo6at_Jg/index.html and have the routers set up as they show. I also set up the vty lines for telnet as shown here: GNS3 - Telnet issue.
I am able to telnet from R2 to R1 using telnet 10.1.1.1. On the screen, in the Topology Summary it shows the telnet address as 192.168.0.10 5000.
If I try to telnet from ubuntu bash terminal, to 192.168.0.10 it telnets to my computer, and asks for my login for my laptop. If I add the 5000 it goes to R1 as if I started a console in GNS, and shows me the same info I would see there, but doesn't ask for a passowrd, even though it is set to ask for one. If I try to telnet to 10.1.1.1 it doesn't go through. In the book I am using, (a guide to networking and python) he is able to log in via telnet from the terminal, so I can't understand why I am unable to do as he does.
I understand why the first part happens, as my laptop's ip is 192.168.0.10, so I followed this page: https://help.ubuntu.com/lts/serverguide/network-configuration.html.en and tried changing the ip, and it had two showing for eth1, one with the new ip and one still as 192.168.0.10, when I did "ip address show dev enp0s25."
I am also running apache2 and wondered if that might interfere with GNS3?
So now I am totally confused, as I can log in one way and not the other, and can't understand why not.
