SSH problem

Vusal jafarov
Level 1
Level 1

Hi everyone, I am working with cisco switch WS-C3750X-24,

On my running configuration there is nothing under VTY and console line it like this:

line con 0
line vty 5 15

there is not any information regarding "transport input SSH or telnet."

But i am getting vulnerability regarding SSH weak key exchange algorithms enabled and SSH server CBC mode cypher enabled.

So, my question is that how can I see SSH CBC mode cyphers and key exchange algorithms?

or how can I solve the vulnerabilities which I mentioned above?

"sh ip ssh" command result is showing only version of SSH and that is all.

Thanks, in advance.

Hello,

which IOS version and which image/template are you running ?

Do you see anything when you add a domain name and generate an RSA key ?

3750(config)#ip domain-name cisco.com
3750(config)#crypto key generate rsa modulus 2028

I am using (C3750-ADVIPSERVICESK9-M) image and 12.2(46) SE IOS version.

Domain name is added but could not find something detailed about crypto key.

On this old platform you can't configure these settings. They were introduced in newer IOS releases that the 3750-X is not capable to run.
