Wildcard SSL certificates + ISPConfig?
Hi Guys,

We've got a wildcard ssl certificate to use with some of the sites on our server.

So we've got:

and ssl cerficiates for (for example)..

How would we add these in ISPconfig? Alias domains are not shown in the drop down when you select which site you want securing.

Thats not a problem as they are not relevant for serving ssl sites, thhey are only used to create a new ssl certificate. As you have already a ssl cert, the selcted ssl domain does not matter.

Ahh yes ofcourse i hadn't considered that. Just ip and away you go I guess. Cheers yet again till. I'm going to paint a picture of you and hang you on my wall.

Sorry, Till. One more question. I can't find it mentioned in the manual. The IP addresses that you add in system->IP addresses. Should they be the public IP's or the internal IPs if they're natted?

I'm guessing internal but just wanted to check. :)

Inside a NAT enviroment, you use internal IP addresses for websites and external IP addresses for DNS records.

Hi, sorry there seems to be something weird here.

I had an error which said that localhost.localdomain isn't the correct certificate for the requested hostname so i moved /etc/conf/ssl.conf which is default centos installation and restarted httpd.

I added the site in ispconfig with the server in debug mode and in the log you can see that it's creating the ssl cert it /var/www/* and the last modified time of /etc/httpd/conf/sites-available/ is when the update is however there's no mention in that file of any ssl setup and running netstat shows httpd isn't listening on 443.

The file is thus:

#  Access Control:

#<Location />
#SSLRequire (    %{SSL_CIPHER} !~ m/^(EXP|NULL)/ \
#            and %{SSL_CLIENT_S_DN_O} eq "Snake Oil, Ltd." \
#            and %{SSL_CLIENT_S_DN_OU} in {"Staff", "CA", "Dev"} \
#            and %{TIME_WDAY} >= 1 and %{TIME_WDAY} <= 5 \
#            and %{TIME_HOUR} >= 8 and %{TIME_HOUR} <= 20      ) \
#          or %{REMOTE_ADDR} =~ m/^192\.76\.162\.[0-9]+$/

#  SSL Engine Options:
#  Set various options for the SSL engine.
#  o FakeBasicAuth:
#    Translate the client X.509 into a Basic Authorisation.  This means that
#    the standard Auth/DBMAuth methods can be used for access control.  The
#    user name is the `one line' version of the client's X.509 certificate.
#    Note that no password is obtained from the user. Every entry in the user
#    file needs this password: `xxj31ZMTZzkVA'.
#  o ExportCertData:
#    This exports two additional environment variables: SSL_CLIENT_CERT and
#    SSL_SERVER_CERT. These contain the PEM-encoded certificates of the
#    server (always existing) and the client (only existing when client
#    authentication is used). This can be used to import the certificates
#    into CGI scripts.
#  o StdEnvVars:
#    This exports the standard SSL/TLS related `SSL_*' environment variables.
#    Per default this exportation is switched off for performance reasons,
#    because the extraction step is an expensive operation and is usually
#    useless for serving static content. So one usually enables the
#    exportation for CGI and SSI requests only.
#  o StrictRequire:
#    This denies access when "SSLRequireSSL" or "SSLRequire" applied even
#    under a "Satisfy any" situation, i.e. when it applies access is denied
#    and no other module can change it.
#  o OptRenegotiate:
#    This enables optimized SSL connection renegotiation handling when SSL
#    directives are used in per-directory context.
#SSLOptions +FakeBasicAuth +ExportCertData +StrictRequire
<Files ~ "\.(cgi|shtml|phtml|php3?)$">
    SSLOptions +StdEnvVars
<Directory "/var/www/cgi-bin">
    SSLOptions +StdEnvVars

#  SSL Protocol Adjustments:
#  The safe and default but still SSL/TLS standard compliant shutdown
#  approach is that mod_ssl sends the close notify alert but doesn't wait for
#  the close notify alert from client. When you need a different shutdown
#  approach you can use one of the following variables:
#  o ssl-unclean-shutdown:
#    This forces an unclean shutdown when the connection is closed, i.e. no
#    SSL close notify alert is send or allowed to received.  This violates
#    the SSL/TLS standard but is needed for some brain-dead browsers. Use
#    this when you receive I/O errors because of the standard approach where
#    mod_ssl sends the close notify alert.
#  o ssl-accurate-shutdown:
#    This forces an accurate shutdown when the connection is closed, i.e. a
#    SSL close notify alert is send and mod_ssl waits for the close notify
#    alert of the client. This is 100% SSL/TLS standard compliant, but in
#    practice often causes hanging connections with brain-dead browsers. Use
#    this only for browsers where you know that their SSL implementation
#    works correctly.
#  Notice: Most problems of broken clients are also related to the HTTP
#  keep-alive facility, so you usually additionally want to disable
#  keep-alive for those clients, too. Use variable "nokeepalive" for this.
#  Similarly, one has to force some clients to use HTTP/1.0 to workaround
#  their broken HTTP/1.1 implementation. Use variables "downgrade-1.0" and
#  "force-response-1.0" for this.
SetEnvIf User-Agent ".*MSIE.*" \
        nokeepalive ssl-unclean-shutdown \
        downgrade-1.0 force-response-1.0

#  Per-Server Logging:
#  The home of a custom SSL log file. Use this when you want a
#  compact non-error SSL logfile on a virtual host basis.
CustomLog logs/ssl_request_log \
          "%t %h %{SSL_PROTOCOL}x %{SSL_CIPHER}x \"%r\" %b"

Any ideas?

till 7th December 2010 15:22

The ssl config is only written if all required ssl files are there in ssl directory of the website (the crt and the .key file). When that requirement is met, ispconfig writes the ssl configuration and tries to restart apache, if the restart of apache fails, it rolls back to the last working configuration state (vhost file) and stores a copy of the non working vhost configuration in the sites-available folder with a extension to the name. The extension is .error or so if I remember correctly.

Xenocide 7th December 2010 15:34

That's great cheers Till. So where does the key file go? in the ssl dir there's and which field should be the .key?

till 7th December 2010 19:19

The key is not in the ispconfig interface for security reasons. Normally you create certificates in ispconfig and the key is stored in the key file only. If you have created a external certificate, you will have to add the key file manually in the ssl folder. It has the base file name like the other files in the ssl folder and ends with .key
