The following displays the IOS configuration related to the CA:
The enrollment line tells how (the method, here an http url) to contact the PKI software. Note that you must omit the pkiclient.exe filename at the end which is automatically add by IOS. The serial-number tells IOS to include the serial number in the request. Cisco IOS (Internetworking Operating System) software is the platform that delivers network services and enables networked applications. Cisco routers and access servers run the industry-leading Cisco IOS software. Cisco IOS software seamlessly links heterogeneous media and devices across the broadest set of protocols.
- The enrollment line tells how (the method, here an http url) to contact the PKI software. Note that you must omit the pkiclient.exe filename at the end which is automatically add by IOS.
- The serial-number tells IOS to include the serial number in the request.
- The name of the trust point you use MUST MATCH exactly the short name of your CA in EJBCA (FMSCA in this example).
Then use the following command to fetch the CA certificate:
Next, login to EJBCA, and create a new entity profile according to the following example:
Then, do the password enrollment using the command:
Check your ejbca logs, you should see something like:
So, you know you must add an entity using the serial number as username, the password you define in IOS, and serialNumber/unstructuredNamed as subject DN fields.
After adding the end entity, do the password enrollment again. If you see this you have enrolled successfully:
There is a Cisco 7200 emulator called dynamips available and a graphical front end GNS3.
The following describes how to configure and enroll directly with EJBCA using GNS3 on Ubuntu 8.10:
Note that this requires EJBCA version 3.8.1 or later.
Configure the host and gns3 to be able to communicate with each other, allowing the router can connect to EJBCA on the host computer. This is taken from http://www.blindhog.net/linux-bridging-for-gns3-lan-communications/'.
Start gns3:
Configure with IOS image, for example c7200-jk9s-mz.124-13b.bin (an image with crypto commands), it's available on the net. Also configure a simple topology:
- drag cloud to topology window
- drag c7200 to topology window
- configure cloud and add tap0 interface
- add manual link from cloud to c7200
- start c7200
- open console on c7200
- enter configuration and configure FastEthernet0/0 with ip 10.10.10.98/255.255.255.0
Now you should be able to ping the host computer, where EJBCA is running.
Next, do the actual enrollment as described above, using the following commands:
Cisco Ios 15 License Keygen Key
Check the log for the username of the user you must create is called. create end entity profile and user with DN containing SN=FFFFFF and unstructuredName=Router, as seen in the log file (FFFFFF and Router are the default values in the simulator).
You can always look at the defined trustpoints using the command:
If you are enrolling towards an RA instead, issue the following commands (Refer to the External RA documentation for information on how to set up an external RA for SCEP).
Note that this would only have a chance to work in EJBCA 3.8.1 and later, and actually it does not work due to the following error in Cisco. If you have any ideas, please contact us.
Lets say you have a Cisco router that’s running an out of date IOS version and want to get a more recent image. It’s safe to say you’ll want to avoid resorting to piracy, Perhaps you don’t want to spend the money on a SMARTnet subscription. There’s a way to legally obtain an updated version that many people over look, security updates.
As it stands, CISCO’s security vulnerability policy states that (emphasis mine):
Cisco Ios 15 License Keygen Generator
As a special customer service, and to improve the overall security of the Internet, Cisco may offer customers free of charge software updates to address security problems. If Cisco has offered a free software update to address a specific issue, noncontract customers who are eligible for the update may obtain it by contacting the Cisco TAC using any of the means described in the Contact Summary section of this document. To verify their entitlement, individuals who contact the TAC should have available the URL of the Cisco document that is offering the update.
Great! So we can probably get free updates if they fix a security issue, so what next? Head over to a handy on-line Cisco tool to identify what vulnerabilities are present in the version of IOS you’re running. Paste in the output of the “show ver” command and you’ll be presented with a list of vulnerabilities affecting your device.
With that information, send TAC Support an e-mail including the output of the “show ver” command and the list of vulnerabilities and you will be sent a one-off link to obtain the latest IOS image for your device, free of charge.
