2. router (Config)# ip domain-name example.com
Note | Secure Shell (SSH) may generate an additional RSA key pair if you generate a key pair on a router having no RSA keys. The additional key pair is used only by SSH and will have a name such as {router_FQDN }.server. For example, if a router name is “router1.cisco.com,” the key name is “router1.cisco.com.server.” |
Modulus Length
Router | 360 bits | 512 bits | 1024 bits | 2048 bits (maximum) |
---|---|---|---|---|
Cisco 2500 | 11 seconds | 20 seconds | 4 minutes, 38 seconds | More than 1 hour |
Cisco 4700 | Less than 1 second | 1 second | 4 seconds | 50 seconds |
Syntax Description : Optional Strings to embed with SSH Crypto key
general-keys | (Optional) Specifies that a general-purpose key pair will be generated, which is the default. | ||
usage-keys | (Optional) Specifies that two RSA special-usage key pairs, one encryption pair and one signature pair, will be generated. | ||
signature | (Optional) Specifies that the RSA public key generated will be a signature special usage key. | ||
encryption | (Optional) Specifies that the RSA public key generated will be an encryption special usage key. | ||
labelkey-label | (Optional) Specifies the name that is used for an RSA key pair when they are being exported.If a key label is not specified, the fully qualified domain name (FQDN) of the router is used. | ||
exportable | (Optional) Specifies that the RSA key pair can be exported to another Cisco device, such as a router. | ||
modulusmodulus-size | (Optional) Specifies the IP size of the key modulus.By default, the modulus of a certification authority (CA) key is 1024 bits. The recommended modulus for a CA key is 2048 bits. The range of a CA key modulus is from 350 to 4096 bits.
| ||
storagedevicename: | (Optional) Specifies the key storage location. The name of the storage device is followed by a colon (:). | ||
redundancy | (Optional) Specifies that the key should be synchronized to the standby CA. | ||
ondevicename: | (Optional) Specifies that the RSA key pair will be created on the specified device, including a Universal Serial Bus (USB) token, local disk, or NVRAM. The name of the device is followed by a colon (:).Keys created on a USB token must be 2048 bits or less. |
Command | Description |
---|---|
copy | Copies any file from a source to a destination, use the copy command in privileged EXEC mode. |
cryptokeystorage | Sets the default storage location for RSA key pairs. |
debugcryptoengine | Displays debug messages about crypto engines. |
hostname | Specifies or modifies the hostname for the network server. |
ipdomain-name | Defines a default domain name to complete unqualified hostnames (names without a dotted-decimal domain name). |
showcryptokeymypubkeyrsa | Displays the RSA public keys of your router. |
show crypto pki certificates | Displays information about your PKI certificate, certification authority, and any registration authority certificates. |

Problem
I’ve lost count of the number of times this has happened to me! Most of my colleagues prefer to use the ASDM for remote management, but if (like me) you work at command line, then sometimes people <ahem> forget to generate the RSA keypair when deploying a firewall. Then even if SSH access and AAA is setup correctly, you still can’t get in via SSH. Instead you see the following;
RoyalTS and RoyalTSX: ssh_exchange_identification: Connection closed by remote host.
PuTTY: PuTTY Fatal Error: Server unexpectedly closed network connection.
SecureCRT: Connection closed.

OSX/Linux: ssh_exchange_identification: Connection closed by remote host.
Now at command line you can fix this with a ‘Crypto Key Generate RSA Modulus 2048‘ command, but you can’t get to command line only ASDM.

On older versions of the ASDM you could generate the keypair in the Identification Certificates section (well you still can but only if you are also generating a certificate request file). Generate rsa key pair nodejs. So, as we are command line warriors, lets use the ASDM’s command line!
