Ssh -c 3des -p 2002 -x -v 10.13.1.99 Restrict SSH Access to a Subnet If Philly is attached to the Carter Port 2, then you can configure SSH to Philly through Carter from Reed with this command: ssh -v 2 -c aes256-cbc -m hmac-shal-160 -p 2002 10.31.1.99 If you need outbound SSH terminal-line authentication, you can configure and test SSH for outbound reverse Telnets through Carter, which acts as a comm server to Philly. Router(conf-ssh-pubkey-data)#end Add SSH Terminal-Line Access Exit the current mode and return to privileged EXEC mode. (This step is optional.) Router(conf-ssh-pubkey-data)#key-hash ssh-rsa Ĩ. Router(conf-ssh-pubkey-user)#key-stringħ. Specify the RSA public key of the remote peer. Configure SSH-RSA keys for user and server authentication. Issue this command to SSH from the Cisco IOS SSH client (Reed) to the Cisco IOS SSH server (Carter) to test this: ssh -v 2 -c aes256-cbc -m hmac-sha1-160 -l cisco 10.31.1.99 Setup an IOS Router as an SSH Server that Performs RSA-based User AuthenticationĬomplete these steps to configure the SSH server to perform RSA-based authentication.Ģ. !- Instead of aaa new-model, you can use the login local command. In this case, Telnet is disabled and only SSH is supported. !- Step 4: By default the vty transport is Telnet. !- Step 3: Generate an SSH key to be used with SSH. !- Step 2: Configure the DNS domain of the router.

!- The aaa new-model command causes the local username and password on the router to be used in the absence of other AAA statements. !- Step 1: Configure the hostname if you have not previously done so. The Cisco IOS SSH client configuration on Reed is the same as required for the SSH server configuration on Carter. This puts these devices in a client-server arrangement, where Carter acts as the server, and Reed acts as the client. If you want to have one device act as an SSH client to the other, you can add SSH to a second device called "Reed". Enable SSH transport support for the vty. There are four steps required to enable SSH support on a Cisco IOS router:Ĥ. Set Up an IOS Router or Switch as SSH Client Test to ensure that non-SSH users cannot Telnet to the router "Carter". If you want to prevent non-SSH connections, add the transport input ssh command under the lines to limit the router to SSH connections only. Optional Configuration Sets Prevent Non-SSH Connections

After you add the SSH configuration, test your ability to access the router from the PC and UNIX station. !- Generate an SSH key to be used with SSH.Īt this point, the show crypto key mypubkey rsa command must show the generated key. In order to test authentication with SSH, you have to add to the previous statements in order to enable SSH on Carter and test SSH from the PC and UNIX stations. Note: Throughout this document vty is used to indicate "Virtual Terminal Type". (Authentication through the line password is not possible with SSH.) This example shows local authentication, which lets you Telnet into the router with username "cisco" and password "cisco." Authentication can be with a local username and password or with an authentication, authorization, and accounting (AAA) server that runs TACACS+ or RADIUS. Test Authentication Authentication Test without SSHįirst test the authentication without SSH to make sure that authentication works with the router Carter before you add SSH. Refer to Cisco Technical Tips Conventions for more information.

SSH Version 2.0 (SSH v2) support was introduced in Cisco IOS platforms and images start in Cisco IOS Software Release 12.1(19)E. SSH terminal-line access (also known as reverse-Telnet) was introduced in Cisco IOS platforms and images start in Cisco IOS Software Release 12.2.2.T.SSH was introduced into these Cisco IOS platforms and images: The information in this document is based on Cisco IOS 3600 Software (C3640-IK9S-M), Release 12.2(2)T1. If your network is live, ensure that you understand the potential impact of any command. All of the devices used in this document started with a cleared (default) configuration. The information in this document was created from the devices in a specific lab environment. The Cisco IOS image used must be a k9(crypto) image in order to support SSH.
