scp configurations on the cisco 1841 router

[Mmiselo]

Good day,

I have implemented the following to setup scp connection between our routers and backup server. I have added the configurations on the Cisco 2900 and Cisco 1900 routers.

Now I can't run the  "ip ssh pubkey-chain and key-string" commands on the Cisco 1841. May you please help suggest some commands I can run on the cisco 1800 router to be able to add the scp key.

ip ssh pubkey-chain
key-string
ssh-rsa AAAAB3NaC1yc2EAAAAAQABAAABAQDaPu6jj037

[Mmiselo]

It should be available in 15.0(1)M as doc below

http://www.cisco.com/c/en/us/td/docs/ios-xml/ios/security/d1/sec-d1-cr-book/sec-cr-i3.html#wp1254331478

when i check the 124.15T it brings me back to the exact same page above and that say only introduced in v15

#http://www.cisco.com/c/en/us/support/ios-nx-os-software/ios-software-release-12-4-15-t/model.html#CommandReferences

Do you get any option when you do ip ssh ? for pubkey in the ver 15 If not you could try upgrade to later release

[Mmiselo]

Version 12.4(15)T8

These are the only options I have,

 authentication-retries  Specify number of authentication retries
  break-string            break-string
  logging                 Configure logging for SSH
  maxstartups             Maximum concurrent sessions allowed
  port                    Starting (or only) Port number to listen on
  rsa                     Configure RSA keypair name for SSH
  source-interface        Specify interface for source address in SSH connections
  time-out                Specify SSH time-out interval
  version                 Specify protocol version to be supported

yes so that would backup what the doc says it was only introduced in v15 not available in 12, do you have it in your other 1841 that's running 15.0(1)M if so you could upgrade the v12 router to that

thanks a lot Mark, that's the highest version we have. I will look for the image for 15.0 (1)
