Re: can anyone explain pls

those numbers in a chain are the result of a crypto key generate rsa in the device required for ssh access possibly to manage the device, along with the local user names preconfigured with their respective secret passwords for local authentication .

Jorge

My name is not there and I am able to log ssh to it.is that part of local user name ?

one more question somenames other name there that are no longer w/ company there name is there ?

is this security issue ?. I know obout security ... "if you don't know you don't trust"

Thanks

Re: can anyone explain pls

Local Usernames are also configured for other purposes such as RA vpn, it would help to see the complete config to understand the purpose of usernames confiured in the router, are you getting prompted when you ssh to the router, if you are not geting prompted with username then your VTY lines are not configured with login local

for example to use local auth with usernames created in router your vty lines would look similar to:

line vty 0 4

login local

transport input ssh

but once again , it will help to look at the complete device configuration, are you doing RA VPN using local auth for those users perhaps, or if you are simply auditing the router and do not know who those names are, then that is part of clean up.
