Can you change the port that Cisco SSH and PDM / ASDM listen on?

I have several cases of PIX and ASA firewalls that have only one public IP address, and ports 22 and 443 are forwarded to internal servers.  I would like to have SSH and PDM/ASDM access to these without having to remote into the server.  How can I change the port that the PIX/ASA listen on from 22 and 443 to something else?

    To change the listening port for the ASDM, just use

    http server enable <new port number>

    For the telnet port - see this post, it has good info....

    Thanks, MikeKane, but that command doesn't work:

    ASA (config)# http server ena 4433
    Usage:  [no] http <local_ip> [<mask>] [<if_name>]
            [no] http server enable
    ASA (config)#

    And the link is for telnet on routers, neither are the issue.

    Any other ideas?

    What version of the ASA are you running...  

    On ver 8.0, the command is

    Step 2 To enable the HTTPS server, enter the following command:
    hostname(config)# http server enable [port]

    It seems that ver 7.1 and earlier did not allow for that option....

    Thanks MikeKane.  I would think that Cisco would have made this available in earlier versions.  It just seems to make sense.  I can do it in SonicWalls and other firewalls.  But, your answer is accurate, and thanks for the info!
