Cisco IOS SSHによるリモートアクセスの設定. Switch(config)#hostname tc0001 tc0001(config)#ip domain-name jinnai73.com tc0001(config)#crypto key generate rsa The name for the keys will be: tc0001.jinnai73.com Choose the size of the key modulus in the range of 360 to 2048 for your General Purpose Keys. Choosing a key modulus. Config t crypto key generate rsa exit Then ssh to the router and complete the config. Or just enable telnet if you can get away with it. Config t vty 0 4 transport input ssh telnet exit I have a perl script that does this to reset enable passwords.

Update:Securing Cisco ASA SSH server

  • Mar 30, 2020  Easy configure ssh on Cisco router or switch. For remote connection to router or switch, you need to enable ssh on Cisco router and configure ssh correctly. Easy configure ssh on Cisco router or switch. Then configure the router to use RSA key pair with modulus size of 1024 bites for remote service authentication with “crypto key generate.
  • ASA-5505 (config)# domain-name networkjutsu.com ASA-5505 (config)# crypto key gen rsa mod 4096 ASA-5505 (config)# ssh version 2 ASA-5505 (config)# ssh key-exchange group dh-group14-sha1. As you know, it is a good idea to enable SSH and disable Telnet. Since ASA does not enable SSH and/or Telnet by default, you have less to worry about.
  • How I create RSA key and enable SSH access in Cisco VG202, in a Cisco router I use the next commands(but in a VG not exists): conf t crypto key generate rsa modulus 1024 ip domain-name domain-name ip ssh version 2 ip ssh time-out 120 ip ssh.
  • May 21, 2014  Author, teacher, and talk show host Robert McMillen shows you how to use the Cisco ASA version 9 generate RSA keys command. Public Key Cryptography: RSA. Configuring ASDM & SSH on Cisco ASA.
  • Oct 02, 2015  SSH Config and crypto key generate RSA command. Use this command to generate RSA key pairs for your Cisco device (such as a router). Keys are generated in pairs–one public RSA key and one private RSA key. If your router already has RSA keys when you issue this command, you will be warned and prompted to replace the existing keys with new keys.

Enabling SSH has been covered here but it only talked about routers and switches. How about Cisco ASA? Today, I had to learn how to do it using CLI and not ASDM since I couldn’t find where the equivalent of aaa authentication ssh console LOCAL and crypto key gen rsa mod 4096 in the ASDM. Since I am really new to Cisco ASA, I am not well-versed in issuing commands under CLI. If you are in a similar situation, I suggest to buy this book. Having said that, I’ve always used ASDM when checking out rules, NATs, and etc but I can understand some of the CLI config. Without further ado, here’s how to enable SSH on a Cisco ASA.

As you know, it is a good idea to enable SSH and disable Telnet. Since ASA does not enable SSH and/or Telnet by default, you have less to worry about. But if you have to choose between them, of course pick the SSH.
