    A trick that I use if a little script that sends the output of
    ifconfig to a text file and uploads it to a password-protected web
    address via FTP. When I need to see what my IP is, I just log into my
    protected page and view the current IP.

    I have a cron job scheduled every hour to run the script, and since
    it's a tiny file, it's not a major thing to haev run every hour.

    Here's the contents of the script (which runs on 4.7 thru 4.10):

    /sbin/ifconfig fxp0 | ncftpput -c -u username -p password domain
    /path/to/file/location/my_ip

    Example with fields filled in:

    /sbin/ifconfig fxp0 | ncftpput -c -u madtux -p secretpassword
    google.com /home/google/www/protected_directory/my_ip

    ..where "my_ip" is both the output of the command and the filename.

    To actually view the file, point yer trusty browser to
    http://www.mydomain/protected_directory/my_ip

    and provide the secret answer, after which you'll see the output of ifconfig.

    I had written something a little cleaner that pulls the IP from the
    stdout and writes it to a temp file, which is then uploaded, but I
    can't find it now :P

    Anyway, hope that helps.
