Update II: Final customers testing session added for Saturday, May 9th.
CME plans to install a software update to CME Secure SFTP on Saturday May 9, 2015. With this enhancement, CME will no longer support “Open SSH public key format” that is currently used by some of clearing firms to connect to CME SFTP. Instead CME will now support “SSH Public Key File Format (RFC4716)” effective May 9, 2015.
To help SFTP customers with this enhancement, CME will conduct a final testing in production on Saturday, May 9th. Please note: all firms that utilize public key to access CME SFTP are required to participate in Production testing on May 9th. If you do not participate in this testing, you will risk your firms’ ability to access CME SFTP following the upgrade.
This change will impact connectivity to the following CME SFTP sites:
To help with this enhancement, CME will convert the majority of the Open SSH Public Keys to SSH Public Key File Format RFC4716. Some customers with special public keys will need to convert their current production keys to RFC4716 format. CME is directly reaching out to those customers and providing them with key conversion instructions.
Firms can test this enhancement now by connecting to the CME Test SFTP site. Below please find the site information and testing procedure:
Please note the following regarding the Test SFTP site.
