ssh version 2.99

What is ssh version 2.99? I can find documentation on 1.5, 1.99, and 2.0. After working with some crypto pki certificates ssh is now reporting as version 2.99 which is breaking some programs attempts to ssh. 'ip ssh version 2' has been run.

router#show ip ssh

SSH Enabled - version 2.99

Authentication timeout: 120 secs; Authentication retries: 3

router#show ssh

Connection Version Mode Encryption Hmac State Username

514 2.0 IN aes128-cbc hmac-sha1 Session started user1

514 2.0 OUT aes128-cbc hmac-sha1 Session started user1

515 2.0 IN aes128-cbc hmac-md5 Session started user2

515 2.0 OUT aes128-cbc hmac-md5 Session started user2

%No SSHv1 server connections running.

Re: ssh version 2.99

SSH Enabled - version 2.99 ,It is probably the OpenSSH version.

Cisco IOS SSH is derived from OpenSSH code.

ssh version 2.99

Bug ID CSCsq51052

Fixed in 12.2(54)SG

Workaround:


The following workaround can be implemented if the ouput of the "show ip ssh" command indicates version 2.99, as in the following example:


Router#show ip ssh

SSH Enabled - version 2.99

Authentication timeout: 120 secs; Authentication retries: 3

Router#


If version "2.99" is reported, proceed to configure the required SSH version, ie:


Router#configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)#ip ssh version 2

Router(config)#end


The execution of a "show ip ssh" command should now indicate the correct version:


Router#show ip ssh

SSH Enabled - version 2.0

Authentication timeout: 120 secs; Authentication retries: 3

Router#
