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.

SSH Enabled - version 2.99 ,It is probably the OpenSSH version.
Cisco IOS SSH is derived from OpenSSH code.

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#
