Shotgun Shopping

We want to get a semi-auto 12 gauge shotgun for hunting waterfowl (and maybe deer). I like the box mags, so there are a couple of options we’re considering:

TriStar KRX — cheap gun available at Cabelas. Fixed stock.

Panzer KMR — A little more expensive. Can replace stock, but not telescoping.

UTAS looks like they’ve got a gun with an adjustable stock in the 500 dollar range

Remington 870 DM looks great too

Where did THAT come from? (PHP class)

I’ve got some code that is cobbled together from a couple of different places & it’s got namespace collisions that wouldn’t exist if I’d been starting from scratch. But I’ve got what I’ve got … and, occasionally, new code falls over because a class has already been declared.

Luckily, there’s a way to find out from where a class was loaded:

			$strClassName = "Oracle_Cred";
			if( class_exists($strClassName) ){
				$reflector = new \ReflectionClass($strClassName);
				echo "Class $strClassName was loaded from " . $reflector->getFileName();
				echo "Class $strClassName does not exist yet";

Spatchcock butchering method

We butchered our broilers and ducks for the year. In a larger household, a whole bird is probably a perfectly reasonable amount of food. But, for us? It’s too much food. Half a bird is a lot more reasonable.

In looking at techniques for grilling and smoking poultry, we came across spatchcocking — basically splitting the whole bird along the spine so it lays flat. It looked like a much quicker way to butcher — and, if we didn’t want to have a whole bird in the end anyway it isn’t like the approach would be counterproductive.

So we’ve been butchering by detaching the crop, airway, and throat. Placing the bird so the backbone is up and the neck facing you, cut along the spine. It’s a little tricky to cut at the hip joint — you’ve got to find the right spot to snip, but the oyster is always included with the leg using this method — and be careful not to pierce intestines. You can leave the spine with one half or cut down the other side of the spine. Cut around the vent, then clear out all of the innards — one entire mass is removed. Either finish spatchcocking to store a whole bird or use shears to cut along the breastbone and have two halves. I’ve found this approach to be a lot quicker than the normal technique — and, since the carcass is open, removing the innards is very easy.

Bash – Spaces, Quotes, and String Replacement

Had to figure out how to do string replacement (Scott wanted to convert WMA files to similarly named MP3 files) and pass a single parameter that has spaces into a shell script.

${original_string/thing_to_find/thing_to_replace_there} does string replacement. And $@ is the unexpanded parameter set. So this wouldn’t work if we were trying to pass in more than one parameter (well, it *would* … I’d just have to custom-handle parameter expansion in the script)

SSO In Apache HTTPD – OAuth2

PingID is another external authentication source that looks to be replacing ADFS at work in the not-too-distant future. Unfortunately, I’ve not been able to get anyone to set up the “other side” of this authentication method … so the documentation is untested. There is an Apache Integration Kit available from PingID ( Documentation for setup is located at

Alternately, you can use OAuth2 through Apache HTTPD to authenticate users against PingID. To set up OAuth, you’ll need the mod_auth_openidc module (this is also available from the RedHat dnf repository). You’ll also need the client ID and secret that make up the OAuth2 client credentials. The full set of configuration parameters used in /etc/httpd/conf.d/auth_openidc.conf (or added to individual site-httpd.conf files) can be found at

As I am not able to register to use PingID, I am using an alternate OAUTH2 provider for authentication. The general idea should be the same for PingID – get the metadata URL, client ID, and secret added to the oidc configuration.

Setting up Google OAuth Client:

Register OAuth on Google Cloud Platform ( – Under “API & Services”, select “OAuth Consent Screen”. Build a testing app – you can use URLs that don’t go anywhere interesting, but if you want to publish the app for real usage, you’ll need real stuff.

Under “API & Services”, select “Credentials”. Select “Create Credentials” and select “OAuth Client ID”

Select the application type “Web application” and provide a name for the connection

You don’t need any authorized JS origins. Add the authorized redirect URI(s) appropriate for your host. In this case, the internal URI is my docker host, off port on 7443. The generally used URI is my reverse proxy server. I’ve had redirect URI mismatch errors when the authorized URIs don’t both include and exclude the trailing slash. Click “Create” to complete the operation.

You’ll see a client ID and secret – stash those as we’ll need to drop them into the openidc config file. Click “OK” and we’re ready to set up the web server.

Setting Up Apache HTTPD to use mod_auth_openidc

Clone the mod_auth_openidc repo ( – I made one change to the Dockerfile. I’ve seen general guidance that using ENV to set DEBIAN_FRONTEND to noninteractive is not ideal, so I replaced that line with the transient form of the directive:

ARG DEBIAN_FRONTEND=noninteractive

I also changed the index.php file to

RUN echo "<html><head><title>Sample OAUTH Site</title><head><body><?php print $_SERVER['OIDC_CLAIM_email'] ; ?><pre><?php print_r(array_map(\"htmlentities\", apache_request_headers())); ?></pre><a href=\"/protected/?\">Logout</a></body></html>" > /var/www/html/protected/index.php

Build an image:

docker build -t openidc:latest .

Create an openidc.conf file on your file system. We’ll bind this file into the container so our config is in place instead of the default one. In my example, I have created “/opt/openidc.conf”. File content included below (although you’ll need to use your client ID and secret and your hostname). I’ve added a few claims so we have access to the name and email address (email address is the logon ID)

Then run a container using the image. My sandbox is fronted by a reverse proxy, so the port used doesn’t have to be well known.

docker run --name openidc -p 7443:443 -v /opt/openidc.conf:/etc/apache2/conf-available/openidc.conf -it openidc /bin/bash -c "source /etc/apache2/envvars && valgrind --leak-check=full /usr/sbin/apache2 -X"

* In my case, the docker host is not publicly available. I’ve also added the following lines to the reverse proxy at

ProxyPass /protected
ProxyPassReverse /protected

Access (I haven’t published my app for Google’s review, so it’s locked down to use by registered accounts only … at this time, that’s only my ID. I can register others too.) You’ll be bounced over to Google to provide authentication, then handed back to my web server.

We can then use the OIDC_CLAIM_email — $_SERVER[‘OIDC_CLAIM_email’] – to continue in-application authorization steps (if needed).

openidc.conf content:

LogLevel auth_openidc:debug

LoadModule auth_openidc_module /usr/lib/apache2/modules/

OIDCSSLValidateServer On

OIDCClientSecret uuid-thingU4W

OIDCCryptoPassphrase S0m3S3cr3tPhrA53
OIDCAuthNHeader X-LJR-AuthedUser
OIDCScope "openid email profile"

     AuthType openid-connect
     Require valid-user

OIDCOAuthSSLValidateServer On
OIDCOAuthRemoteUserClaim Username


Active Directory Federated Services (ADFS) can be used by servers inside or outside of the company network. This makes it an especially attractive authentication option for third party companies as no B2B connectivity is required to just authenticate the user base. Many third-party vendors are starting to support ADFS authentication in their out-of-the-box solution (in which case they should be able to provide config documentation), but anything hosted on Apache HTTPD can be configured using these directions:

This configuration uses the module — I’ve built this from the repo. Once mod_auth_mellon is installed, create a directory for the configuration

mkdir /etc/httpd/mellon

Then cd into the directory and run the config script:

/usr/libexec/mod_auth_mellon/ ""


You will now have three files in the config directory – an XML file along with a cert/key pair. You’ll also need the FederationMetadata.xml from the IT group – it should be

Now configure the module – e.g. a file /etc/httpd/conf.d/20-mellon.conf – with the following:

MellonCacheSize 100
MellonLockFile /var/run/mod_auth_mellon.lock
MellonPostTTL 900
MellonPostSize 1073741824
MellonPostCount 100
MellonPostDirectory "/var/cache/mod_auth_mellon_postdata"

To authenticate users through the ADFS directory, add the following to your site config

MellonEnable "auth"
Require valid-user
AuthType "Mellon"
MellonVariable "cookie" 
MellonSPPrivateKeyFile /etc/httpd/mellon/
MellonSPCertFile /etc/httpd/mellon/
MellonSPMetadataFile /etc/httpd/mellon/
MellonIdPMetadataFile /etc/httpd/mellon/FederationMetadata.xml
MellonMergeEnvVars On ":"
MellonEndpointPath /auth/endpoint


Provide the XML file and certificate to the IT team that manages ADFS to configure the relying party trust.

Fortify on Demand Remediation: Cookie Security: Cookie not Sent Over SSL

This is another one that might be a false positive or might be legit. If you look at the documentation for PHP’s setcookie function, you will see the sixth parameter sets a restriction so cookies are only sent over secure connections. If you are not setting this restriction, the vulnerability is legitimate and you should sort that. But … if you followed PHP’s documentation and passed 1 to the parameter? FoD is falsely reporting that the parameter is not set to true.

In this case, the solution is easy enough. Change your perfectly valid 1

to say true

And voila, the vulnerability has been remediated.

Porkbun DDNS API

I’ve been working on a script that updates our host names in Porkbun, but the script had a problem with the type A records. Updating worked fine, but became

Now, in a Bind zone, you just fully qualify the record by post-pending the implied root dot (i.e. instead of “”, you use “”, but Porkbun didn’t understand a fully qualified record. You cannot say the name is null (or “”). You cannot say the name is “” or “”

In what I hope is my final iteration of the script, I now identify cases where the name matches the zone and don’t include the name parameter in the JSON data. Otherwise I include the ‘name’ as the short hostname (i.e. the fully qualified hostname minus the zone name). This appears to be working properly, so (fingers crossed, knock on wood, and all that) our ‘stuff’ won’t go offline next time our IP address changes.
