Can't access the router using SSH and Telnet

[hummer3331973]

Anyone have any ideas why I can't a access this router on Telnet and SSH using Putty?

Thanks,

can you post the whole config?

Yeah - in fact the "transport input ssh" isn't actually what enables SSH, it's actually "crypt key gen rsa" that does it.

line vty 0 4
login local
transport input ssh

That last line should read transport input telnet to allow telnet traffic. Vince is also right, you need to enable SSH on the cisco first by using that command "crypto key generate rsa

And ip domain-name

Need that for ssh...

Ok. If it's not SSH and Telnet, how can I access the router remotely?

I can definitely ping the router, but when trying to connect, I'm getting the error that the remote host is refusing it.

Many thanks,
Newbie

transport input ssh" <-- this lines *disables* telnet access, but does not enable SSH.

You will need to use the console to login.

 

[hummer3331973]

Thanks Vince, will try that.

I notice you said "remotely".

What I do in that sort of case is ring somebody on-site and ask them to see if there is a server or PC next to the switch I need console access to. I ask them to connect the Cisco console lead (which I always leave on-site when I setup a switch/router/FW) to the serial port in the Server/PC. I then RDP to the server/PC, fire up Hypertrm on it and console into the switch, remotely.

I was able to log-in to the router by replacing SSH with Telnet as advised above from the console port.

Thanks.

Hummer3331973,

Just as a side note - unless this is a lab you should configure SSH and disable telnet for security
