I installed a cert for my server a while ago using certbot, and cant remember if I setup as a wildcard or not, What command can I run to see if it is or not?
I want to include two wildcards in an SSL cert (will be) signed by Let's Encrypt: *.*.thost3.de
. Will this cert match any hostnames matching that rule (e.g. example.example.thost3.de
, hello.world.thost3.de
), and can Let's Encrypt accept such wildcards exist in certs they signed?
I want to use wildcards in Apache. What I actually want to do is:
ServerName wiki-*.thost3.de
, and the*
must be accessible by further configurations.- Provide the contents at
/var/www/wiki/*
, where*
is the same as what*
means on the first line.
How to do that?
Hmm... Actually, it's not limited to Apache configs, some external scripts could do the second step, but Apache config is the best when ...

I have a server which I use with my own domain name, with a wildcard DNS record. On the server side, I use the nginxproxy docker image to autogenerate VHosts. This allows me to add new websites/pages/services on the fly with their own subdomain simply by starting a new docker container. I also use the nginxproxy/acme-companion docker image to manage letsencrypt certificates for all of these automaticall ...
I am using apache2 server for a domain which has several subdomains. Each subdomain needs to be on https. I have a wildcard certificate installed for this and it works fine. Now one specific subdomain domain (api.mydomain.com) needs to proxypass to a upstream node service on https. How do I achieve this in the vhost config below:
<VirtualHost *:443>
DocumentRoot /var/www/html
ServerName mydom ...

I have a service example.com
that needs to allow users to host a few files in their own subdomain userpage-userabc.example.com
, similarly as does Github with userabc.github.io
.
I currently use Apache, and each time I want to configure a new domain or subdomain, I have to create manually a new <VirtualHost>
, restart the Apache server, etc.
This is not possible here.
Example: if a visitor crea ...

I've got an Azure FrontDoor (preveiw) Premium endpoint setup and I'm trying to add a custom wildcard domain (*.example.com) so that I can use the Rule Set to direct traffic between server environments setup as origin groups.
I am using Azure DNS, and Azure KeyValut to hold the secret.
The problem I'm facing is that when adding the *.example.com custom domain, it will not let me select the wildcard c ...
Since v5.6.0, libvirt
added a dnsmasq
namespace with the element
, which allows to specify options directly to the underlying dnsmasq server. I'd like to create a wildcard DNS entry for my applications with that option. So I used virsh net-edit
, changed <network>
to <network xmlns:dnsmasq='http://libvirt.org/schemas/network/dnsmasq/1.0'>
and added the following options:
<dnsmasq:o ...

E.g. in my DNS providers UI, I have a A record for the main domain along the lines: mydomain.com.: <my server ip address>
This works fine. I'd like to obtain a wildcard SSL certificate to be able to add several subdomains.
Can I add a record of the form *.mydomain.com: <my server ip address>
Is this normal or sound practice?
