SSH CONFIGURATION

PietroPoliseno27977 — Wed, 22 Apr 2020 08:25:43 GMT

hi everyone i am setting up a lab on cisco packet tracer to create an access via ssh. I created both a dns server (from which the encryption keys will be generated via ssh), two PCs and a switch in the center. On the switch I configured the vlan 1 (the only vlan), with ip 192.168.1.5 while the dns server, pc1 and pc 2 respectively 1.2, 1.3 and 1.4.
Pings work properly.
When I go to pc1 from the telnet / ssh icon and try to connect with ssh with ip 192.168.1.5 it always gives me this message:
The current session has closed. Do you want restablish a new session with the previous session options?

However in the ssh configuration I set username and password as per exercise in the initial ssh configuration
What did I do wrong?

Thanks

Are you trying to ssh to the switch?

there is no ip address configured on the switch

try this on switch -

int vlan 1
ip add 192.168.1.5 255.255.255.0
no sh
exit

line vty 0 4
transport input ssh 
exit

Then use the telnet/ssh client to connect to 192.168.1.5 from the PC.

Hope this helps

it worked, however, before launching the commands you posted, I launched show running config and I saw that vlan1 was set as why? Then why did you use the "no sh" command?

however I had skipped the transport input ssh command. But in the ccna book that I am studying official book icdn / 1 and 2 there is the configuration of the ssh the procedure then after a few more pages it talks about the transport input command ssh I thought that the exercise could already be done without the command was there in my opinion mistake

the packet tracer file you gave had vlan 1 administratively shutdown and no ip address

once you assign an ip address you have to do unshut the interface to make it active

thats why i used no shut

yes thank you for everything I finished the chapter and I understood everything. From what I understand cisco you must first finish the chapter you cannot immediately follow the examples page by page but first finish the chapter and then execute. anyway thanks for everything
