Create and Configure SSL bundle file for GoGetSSL issued certificate in Apache Webserver on Linux

gogetssl-install-certificate-on-linux-howto-sslcertificatechainfile-obsolete

I had a small task to configure a new WildCard SSL for domains on a Debian GNU / Linux Jessie running Apache 2.4.25.

The official documentation on how to install the SSL certificate on Linux given by GoGetSSL (which is by COMODO was obsolete as of time of writting this article and suggested as install instructions:
 

SSLEngine on
SSLCertificateKeyFile /etc/ssl/ssl.key/server.key
SSLCertificateFile /etc/ssl/ssl.crt/yourDomainName.crt
SSLCertificateChainFile /etc/ssl/ssl.crt/yourDomainName.ca-bundle


Adding such configuration to domain Vhost and testing with apache2ctl spits an error like:

 

root@webserver:~# apache2ctl configtest
AH02559: The SSLCertificateChainFile directive (/etc/apache2/sites-enabled/the-domain-name-ssl.conf:17) is deprecated, SSLCertificateFile should be used instead
Syntax OK

 


To make issued GoGetSSL work with Debian Linux, hence, here is the few things done:

The files issued by Gogetssl.COM were the following:

 

AddTrust_External_CA_Root.crt
COMODO_RSA_Certification_Authority.crt
the-domain-name.crt


The webserver had already SSL support via mod_ssl Apache module, e.g.:

 

root@webserver:~# ls -al /etc/apache2/mods-available/*ssl*
-rw-r–r– 1 root root 3112 окт 21  2017 /etc/apache2/mods-available/ssl.conf
-rw-r–r– 1 root root   97 сеп 19  2017 /etc/apache2/mods-available/ssl.load
root@webserver:~# ls -al /etc/apache2/mods-enabled/*ssl*
lrwxrwxrwx 1 root root 26 окт 19  2017 /etc/apache2/mods-enabled/ssl.conf -> ../mods-available/ssl.conf
lrwxrwxrwx 1 root root 26 окт 19  2017 /etc/apache2/mods-enabled/ssl.load -> ../mods-available/ssl.load


For those who doesn't have mod_ssl enabled, to enable it quickly run:

 

# a2enmod ssl


The VirtualHost used for the domains had Apache config as below:

 

 

 

NameVirtualHost *:443

<VirtualHost *:443>
    ServerAdmin support@the-domain-name.com
    ServerName the-domain-name.com
    ServerAlias *.the-domain-name.com the-domain-name.com

    DocumentRoot /home/the-domain-namecom/www
    SSLEngine On
#    <Directory />
#        Options FollowSymLinks
#        AllowOverride None
#    </Directory>
    <Directory /home/the-domain-namecom/www>
        Options Indexes FollowSymLinks MultiViews
        AllowOverride None
        Include /home/the-domain-namecom/www/htaccess_new.txt
        Order allow,deny
        allow from all
    </Directory>

    ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
    <Directory "/usr/lib/cgi-bin">
        AllowOverride None
        Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
        Order allow,deny
        Allow from all
    </Directory>

    ErrorLog ${APACHE_LOG_DIR}/error.log

    # Possible values include: debug, info, notice, warn, error, crit,
    # alert, emerg.
    LogLevel warn

    CustomLog ${APACHE_LOG_DIR}/access.log combined

#    Alias /doc/ "/usr/share/doc/"
#   <Directory "/usr/share/doc/">
#       Options Indexes MultiViews FollowSymLinks
#       AllowOverride None
#       Order deny,allow
#       Deny from all
#       Allow from 127.0.0.0/255.0.0.0 ::1/128
#   </Directory>
SSLCertificateKeyFile /etc/apache2/ssl/the-domain-name.com.key
SSLCertificateFile /etc/apache2/ssl/chain.crt

 

</VirtualHost>

The config directives enabling and making the SSL actually work are:
 

SSLEngine On
SSLCertificateKeyFile /etc/apache2/ssl/the-domain-name.com.key
SSLCertificateFile /etc/apache2/ssl/chain.crt

 

The chain.crt file is actually a bundle file containing a bundle of the gogetssl CA_ROOT and RSA_Certification_Authority 3 files, to prepare that file, I've used bundle.sh small script found on serverfault.com here I've made a mirror of bundle.sh on www.pc-freak.net here   the script content is as follows:

To prepare the chain.crt  bundle, I ran:

 

sh create-ssl-bundle.sh _iq-test_cc.crt chain.crt
sh create-ssl-bundle.sh _iq-test_cc.crt >chain.crt
sh create-ssl-bundle.sh COMODO_RSA_Certification_Authority.crt >> chain.crt
sh create-ssl-bundle.sh bundle.sh AddTrust_External_CA_Root.crt >> chain.crt


Then I copied the file to /etc/apache2/ssl together with the-domain-name.com.key file earlier generated using openssl command earlier explained in my article how to install RapidSSL certificate on Linux

/etc/apache2/ssl was not previously existing (on Debian Linux), so to create it:

 

root@webserver:~# mkdir /etc/apache2/ssl
root@webserver:~# ls -al /etc/apache2/ssl/chain.crt
-rw-r–r– 1 root root 20641 Nov  2 12:27 /etc/apache2/ssl/chain.crt
root@webserver:~# ls -al /etc/apache2/ssl/the-domain-name.com.key
-rw-r–r– 1 root root 6352 Nov  2 20:35 /etc/apache2/ssl/the-domain-name.com.key

 

As I needed to add the SSL HTTPS configuration for multiple domains, further on I've wrote and used a tiny shell script add_new_vhost.sh which accepts as argument the domain name I want to add. The script works with a sample Skele (Template) file, which is included in the script itself and can be easily modified for the desired vhost config.
To add my multiple domains, I've used the script as follows:
 

sh add_new_vhost.sh add-new-site-domain.com
sh add_new_vhost.sh add-new-site-domain1.com


etc.

Here is the complete script as well:

 

#!/bin/sh
# Shell script to add easily new domains for virtual hosting on Debian machines
# arg1 should be a domain name
# This script takes the domain name which you type as arg1 uses it and creates
# Docroot / cgi-bin directory for the domain, create seperate site's apache log directory
# then takes a skele.com file and substitutes a skele.com with your domain name and directories
# This script's aim is to easily enable sysadmin to add new domains in Debian
sites_base_dir=/var/www/jail/home/www-data/sites/;
# the directory where the skele.com file is
skele_dir=/etc/apache2/sites-available;
# base directory where site log dir to be created
cr_sep_log_file_d=/var/log/apache2/sites;
# owner of the directories
username='www-data';
# read arg0 and arg1
arg0=$0;
arg1=$1;
if [[ -z $arg1 ]]; then
echo "Missing domain name";
exit 1;
fi

Using the script saves a lot of time to manually, copy vhost file and then edit it to change ServerName directive, for vhosts whose configuration is identical and only the ServerName listener has to change, it is perfect to create all necessery domains, I've created a simple text file with each of the domains and run it in a loop:
 

while :; do sh add_new_vhost.sh $i; done < domain_list.txt
 

 

Create PNG, JPG, GIF pictures / images from PDF on Linux

Saturday, February 25th, 2012

I've received a PDF file with a plan for development of a bundle of projects, My task was to evaluate this plan and give feeback on the 44 pages PDF document.

Since don't know of program to directly be able edit PDF files on GNU / Linux ?, my initial idea was to open and convert the PDF to ODT / DOC with OpenOffice (Libre Office) and then edit the ODT file.
Unfortunately Open Office oowrite program was unable to open / visualize the PDF file. My assumption is OO failure to open the PDF is because the PDF was generated on Microsoft Windows with Adobe illustrator or smth.

The idea that came to my mind as alternative, way to edit the PDF file was to convert it in pictures edit and then convert the pictures to PDF.
In other words to follow these 3 steps:
1. Convert the PDF document to multiple images
2. Edit each of the images with GIMP or Inkscape
3. Convert back all images to a single PDF file

Some time ago, I've written an article how to create PDF file from many image files in JPEG, PNG or GIF on Linux

. This prior article was exactly describing how to complete Step 3.Therefore all left was to find a way to convert the PDF file to multiple JPEG / PNG / GIF images.

convert command to convert PDF document to multiple pictures which you can take from my earlier article is:

$ convert *.jpg outputpdffile.pdf
Actually in Step 1 I was aiming to do the opposite of what I've previously done.

Hence, in order to convert the singe Project.PDF file to multiple PNG images, I just switched convert IN / OUT arguments order.

hipo@noah:~/project-pdf-to-images$ convert Project.pdf Project.png
...

I've done the PDF to pictures conversion on my notebook running Debian Squeeze (6.0.2) GNU / Linux.Convertion of the PDF file to 44 images, took 25 seconds on my dual core 1.8 Ghz / 2GB RAM Thinkpad r61.
Afterwards, I've had at hand 44 PNG files generated, e.g.:

hipo@noah:~/project-pdf-to-images$ ls -al Project-*.png |wc -l
44

convert was also smart enough to produce correct file naming. The output file names were:
Project-1.png
Project-2.png
etc.

Nicely each number (-1.png) was corresponding to the respective PDF page. For instance Project-10.png was corresponding to page 10 of the Projects.PDF file

Rather ironically, after convertion of the PDF to pictures, while opening the Project-1.png, I've noticed The GIMP – (The GNU Image Manipulation Program) is capable of directly reading PDF files. GIMP has both the option to open files in layers or separate images 😉
Anyways even if GIMP is used to modify the different PDF pages as layers, once completed GIMP doesn't have the ability to save the file as PDF and therefore once saved the file if merging of layers is done the resulting picture becomes ONE BIG MESS.
Therefore it seems my the 3 steps way e.g.:

1. convertion PDF to pictures
2. picture edit with GIMP or Inkscape
3. convertion of pictures back to PDF

is still the only way to "modify PDF" in Linux or BSDs. I will be glad to hear if someone has come up with a better solution?

 

How to fix “Could not verify this certificate for unknown reasons” SSL certificate lighttpd troubles

Tuesday, June 28th, 2011

Firefox SSL Pro could not verify for uknown reasons solve error

I’ve been issuing new wildcard multiple SSL certificate to renew an expiring ones. After I completed the new certificate setup manually on the server (a CentOS 5.5 Final running SoluSVM Pro – Virtual Private Manager), I launched Firefox to give a try if the certificate is properly configured.

Instead of my expectations that the browser would just accept the certificate without spitting any error messages and all will be fine, insetad I got error with the just installed certificate and thus the browser failed to report the SSL cert is properly authenticated.

The company used to issue the SSL certificate is GlobeSSL – http://globessl.com , it was quite “hassle”, with the tech support as the first certficate generated by globessl was generation based on SSL key file with 4096 key encryption.

As the first issued Authenticated certificate generated by GlobeSSL was not good further on about a week time was necessery to completethe required certificate reissuing ….

It wasn’t just GlobeSSL’s failure, as there were some spam filters on my side that was preventing some of GlobeSSL emails to enter normally, however what was partially their fault as they haven’t made their notification and confirmation emails to pass by a mid-level strong anti-spam filter…

Anyways my overall experience with GlobeSSL certificate reissue and especially their technical support is terrible.
To make a parallel, issuing certificates with GoDaddy is a way more easier and straight forward.

Now let me come back to the main certificate error I got in Firefox …

A bit of further investigation with the cert failure, has led me to the error message which tracked back to the newly installed SSL certificate issues.
In order to find the exact cause of the SSL certificate failure in Firefox I followed to the menus:

Tools -> Page Info -> Security -> View Certificate

Doing so in the General browser tab, there was the following error:

Could not verify this certificate for unknown reasons

The information on Could not verify this certificate for unknown reasons on the internet was very mixed and many people online suggested many possible causes of the issue, so I was about to loose myself.

Everything with the certificate seemed to be configured just fine in lighttpd, all the GlobeSSL issued .cer and .key file as well as the ca bundle were configured to be read used in lighttpd in it’s configuration file:
/etc/lighttpd/lighttpd.conf

Here is a section taken from lighttpd.conf file which did the SSL certificate cert and key file configuration:

$SERVER["socket"] == "0.0.0.0:443" {
ssl.engine = "enable"
ssl.pemfile = "/etc/lighttpd/ssl/wildcard.mydomain.bundle"
}

The file /etc/lighttpd/ssl/wildcard.mydomain.bundle was containing the content of both the .key (generated on my server with openssl) and the .cer file (issued by GlobeSSL) as well as the CA bundle (by GlobeSSL).

Even though all seemed to be configured well the SSL error Could not verify this certificate for unknown reasons was still present in the browser.

GlobeSSL tech support suggested that I try their Web key matcher interfacehttps://confirm.globessl.com/key-matcher.html to verify that everything is fine with my certificate and the cert key. Thanks to this interface I figured out all seemed to be fine with the issued certificate itself and something else should be causing the SSL oddities.
I was further referred by GlobeSSL tech support for another web interface to debug errors with newly installed SSL certificates.
These interface is called Verify and Validate Installed SSL Certificate and is found here

Even though this SSL domain installation error report and debug tool did some helpful suggestions, it wasn’t it that helped me solve the issues.

What helped was First the suggestion made by one of the many tech support guy in GlobeSSL who suggested something is wrong with the CA Bundle and on a first place the documentation on SolusVM’s wiki – http://wiki.solusvm.com/index.php/Installing_an_SSL_Certificate .
Cccording to SolusVM’s documentation lighttpd.conf‘s file had to have one extra line pointing to a seperate file containing the issued CA bundle (which is a combined version of the issued SSL authority company SSL key and certificate).
The line I was missing in lighttpd.conf (described in dox), looked like so:

ssl.ca-file = “/usr/local/solusvm/ssl/gd_bundle.crt”

Thus to include the directive I changed my previous lighttpd.conf to look like so:

$SERVER["socket"] == "0.0.0.0:443" {
ssl.engine = "enable"
ssl.pemfile = "/etc/lighttpd/ssl/wildcard.mydomain.bundle"
ssl.ca-file = "/etc/lighttpd/ssl/server.bundle.crt"
}

Where server.bundle.crt contains an exact paste from the certificate (CA Bundle) mailed by GlobeSSL.

There was a couple of other ports on which an SSL was configured so I had to include these configuration directive everywhere in my conf I had anything related to SSL.

Finally to make the new settings take place I did a lighttpd server restart.

[root@centos ssl]# /etc/init.d/lighttpd restart
Stopping lighttpd: [ OK ]
Starting lighttpd: [ OK ]

After lighttpd reinitiated the error was gone! Cheers ! 😉

A bundle of nice spiritual Movies

Saturday, September 26th, 2009

I thought it would be nice to mention a couple of interesting movies that were quiteedifying.
1. The Chosen – A Jewish Movie talking about a jewish boy life from a jewish perspective,would be interesting since it represents many of the nice jewish traditions.2. Diary of a Country Priest (1954) – A French Catholic movie observing a life of Godinspired Catholic priest, which somehow didn’t fit to the whole catholic church reality,however, his attitude towards life was like old times saints. Just like yoursaviour and Lord Jesus Christ he was rejected and people hated by most of the people.His everyday food consisted in bread and wine. It seems he suffered a stomach cancerdisease which progressed through out the movie. The movie shows the human sufferingand many of the everyday temptations we face as christians, it’s said to be oneof the most notable spiritual movies ever made.3. Nazarin (1959) – A class movie by Nuis Bunuel, mostly in the protestant tradition.The story behind the movie is about a man who does followed the New Testament our Lord’sJesus Christ teaching quite literally. He was followed by some followers who got inspiredby his eagerness and strive for holiness, he was believed to be a modern day saint byhis followers (two women) and later on a dwarf like man.4. Geroi Shipki – A Russian Bulgarian history based movie made to present the Bulgarianbattle for restoration of their country liberty which would be impossible without thehelp of our orthodox brotherly nation (The Russians). Another interesting point forviewers would be how the movie illustrates some similarities between Bulgarians andRussians based on their similar language and their common Orthodox faith.END—–
