so I am setting up a server for a messaging application which is being developed. I am using openfire server for this which I have installed and running on a PC. Right now, the xmpp domain is set to my computer name and server is working on my network, but obviously as its a local name it cannot be accessed from the outside.I am able to access the server from multiple computers on the same network using the Spark messaging client to test the server. So to be able to access my XMPP server from devices outside my network, do I just buy a domain name and set it as my XMPP domain in Openfire settings?
To answer your question, yes, with the following caveats:
You will either have to host the DNS server yourself or have the DNS provider serve the records for you.
A domain must have a static IP to address to point to. A home or a typical small business Internet account does not include a static IP (some providers actively prevent home accounts from serving web pages/services).
You must also configure your firewall to allow a mapping to the internal server.
I would recommend using an external provider to handle the network and hosting services for your program.

I'm currently working on a script that will test the health of an ADFS service. The ADFS service uses the same domain name (split brain DNS) for both intranet access, as well as for public DNS (for internet connections through the proxy servers). If I'm logged into an intranet device and I attempt to perform an SSL connection to the ADFS service, my device will use the intranet IP of the service. If I do the same from a device that is not in the intranet, I will connect to the public facing IP.
I want my script to test the health of both the internal and external service, but I haven't found a way to perform an SSL connection to a certain hostname/fqdn, and use an specific IP depending on the test I'm trying to perform (intranet vs extranet). Connecting directly to the internal/external IP address is not an option, since the ip addresses are not part of the SSL cert subject alternative names.
One option I found Is to create a PS Session to a remote host that has public DNS servers configured, and execute my Extranet test through that PS Session, but Ideally, I would like to run both tests from one single server.
I'm trying to find an option that works in the context of my PowerShell session only, I don't want to change the DNS settings of the server or the global DNS cache since that will result in problems on the server, because it depends on that ADFS service for other services to work.
Any help will be appreciated
I could not find a way to achieve exactly what I asked, so instead, what I did was to deploy a small Rest API in Azure which calls my ADFS service. When I call that Rest API, ADFS receives the query from the Internet, allowing me to achieve test the health of my ADFS service from the internet.
I have two servers , Server #1 one hosted in the office using the office network (this hosts the tableau server on ubuntu server) and the other server Server #2 sitting in another collocated network. The web application is hosted in server #2 and the tableau dashboards are embended on the web application.
When I try to access the application from another public network , the dashboards are working very well, however when I try to access the dashboards from the office network (which hosts the tablueau server ), I get the following error =>
That error is generally caused by one of two issues
The IP Address of Webserver hosting the IFrame was not whitelisted under Trusted Authentication in TSM or Add Trusted IP Addresses or Host Names to Tableau Server
or
The trusted user does not exist on the Tableau server and/or the username does not match what was passed to the webserver from your web application hosting the Iframe.
We have trusted_ticket_expiry set to 240 minutes.

I'm trying to host web pages using Win Server 2016. Currently, I have Jira and my personal web (IIS) servers. Using AWS, I currently have "myec2.com:port1" and "myec2.com/port2" running fine. And I'm planning to buy a domain "myname.com" to be connected to "myec2.long.name.com"
What I hope to do is "myname.com/jira" and "myname.com/mypage" or "jira.myname.com" and "mypage.myname.com" can redirect to Jira server and the IIS server. Is there a way I can achieve this goal?
Thanks in advance.
If you buy a domain like myname.com you will be able to configure any number of sub-domains such as jira.myname.com or mypage.myname.com as you like.
Usually what you would do is point those sub-domains to your server's IP then handle requests to those domains by setting up a web server (like apache or nginx) and configuring a virtual host (apache) or a server block (nginx) for each one of those sub-domains.
I am looking for a little direction to my problem. Short story, I have a website hosted on a web server. I pay a yearly subscription. This year I am planning on taking it off and hosting it internally. I already backed up, restored, and installed all necessary components (on Windows BTW with IIS, PHP, and MySQL). The site works great internal and by IP address externally through a firewall. (IP address for now until my web host subscription expires, then I will forward and register DNS).
But now this is my problem, my website has email functionality which works on my providers server. I want to install a local mail server for my website that will wind up sending and receiving emails through my website. I am lost here. No sure which path I should take. I have installed and used Exchange 2003 in the past just for internal domains, nothing for internet AND internet.
Anyone with ideas, links, suggestions? I see that IIS does support SMTP virtual servers, is this a possible route? If so, what about POP3 or IMAP (incoming) server solutions?
Thanks
Edit
---Update On Situation---
So far I have configured a local exchange server that works with my local webserver. I then created a CNAME in my web host DNS zone for my IP address. I created a simple subdomain for my site redirected to my home web server. Everything works great, internal email through Exchange 2003 from website on IIS, redirected DNS names, almost there. Now I just need to create Internet Mail functionality in Exchange. Went through the Exchanges wizard to "open system" for Internet mail, created new SMTP connector and ....nothing for external mail test. Failed! Thought everything was configured properly. I also tried to open all ports on firewall, 25 and 110.
I'd recommend using something like PostMarkApp to send transactional email from the website, and use hosted email (Google Apps for Domains) for your email. Its a pain to run a real mail server.
Link to Exchange Internet mail SMTP connector configuration:
Configure Exchange Internet Mail SMTP Connector
Well, I did figure it out. I was on the right path and everything was working but I just configured my client wrong and my ISp blocked port 25, duh. CHanged port to unused 366. But here is a little tip for anyone that may need to figure this out in the future.
1)Setup install IIS with default SMTP and NNTP virtual servers.
2)Install Exchange into organization. Internal naming convention doesn't really make a difference between internal to externally if you are behind a firewall. Basically this means you don't have to create a seperate zone in DNS if using this for a seperate domain hosted elsewhere. Hope this didn't confuse anyone.
3)Right click on server name in Exchange System Manager and go to Internet Mail Wizard
4)If you want your clients to hold a different domain email address than your internal you can setup in exchange through
Exchange System Manager >> Recipients >> Recipient Policies
Then add a Masquerade in Default SMTP Virtual Server
5)Have a gmail Internet SMTP connector set to smtp.gmail.com as smart host with a gmail email account settings and TLS checked
6)Default SMTP VS set with outbound port 587 and TLS checked
If you need to change SMTP ports too, don't forget to change not just firewall but also inside Exchange.
I have an application that uses Prosody and XMPP to communicate with Google Talk users. I want the app to be able to communicate with Goole Apps users, but according to this document:
http://www.google.com/support/a/bin/answer.py?hl=en&answer=34143
having Google Apps users talk to any xmpp client outside of #gtalk.com requires creating SRV records.
My question is: How can my app talk to Google Apps users /without/ requiring them to create DNS records for their domain? (This is highly technical and no one does this.)
Is there some way to trick my server into talking to Google's XMPP server instead of looking for a non-existent XMPP endpoint?
This may require a creative solution.. hosts file, firewalls, special DNS settings... anything? Is it possible??
Have your XMPP server configured to talk to a local DNS server that serves up whatever SRV records you want. I suggest dnsmasq, with a configuration like this:
# Never forward plain names (without a dot or domain part)
domain-needed
# Never forward addresses in the non-routed address spaces.
bogus-priv
# A SRV record sending XMPP for the example.com domain to
# xmpp-server.l.google.com port 5269
srv-host=_xmpp-server._tcp.example.com,xmpp-server.l.google.com,5269,5
srv-host=_xmpp-server._tcp.example.com,xmpp-server1.l.google.com,5269,20
srv-host=_xmpp-server._tcp.example.com,xmpp-server2.l.google.com,5269,20
srv-host=_xmpp-server._tcp.example.com,xmpp-server3.l.google.com,5269,20
