I don't know what Branchcache is doing, but I think Apache service and Branchcache service are listening 80 port number. Because I found this information on internet. How can I change port number of Branchecache service and is this action true? If I do it, will Branchcache service continue to run properly?
Thanks a lot.

at my firm we have a jupyterhub/lab installed and is used by roughly 70-100 people in a secure network that can only be accessed to from work. Recently the idea of hosting web-applications for short time use came up, but we are having port problems. User A is running a web application on port 5000, and User B can’t use the port because it is already in use. Port 5000 is default, it can be changed but this is not the behavior we want. Does anyone know of a way for web-applications to run on the same port in the same environment? Have looked into server-proxy but i do not really understand it. Is the way to achieve this really to be running a vm for each user securing that the port is not in use?
Any help is appreciated
The standard behaviour for wildfly-17 (and 18) with microprofile-health-smallrye is, that the /health endpoints are published under the management port.
Is there a way to configure it to use a different port?
That behaviour is difficult in some situations (with docker and kubernetes) to open up the management port completely, and make it accessible, for other "machines" than localhost.
Thanks in advance,
Gabriel
Jeff Mesnil answered my thread on the wildfly-user chat -> It is not possible to run health endpoint on application port. WildFly only expose them to the managment port.
Whilst I could not find a direct answer I did have a similar issue myself and implemented a solution.
I added the flag Dswarm.port.offset=100. For my thorntail set up this shifted all the port by 100.
My solution to publish metrics within a docker swarm, where port 9990 is not exposed, was to write a Proxy-Servlet registered under /metrics that returns the contents of http://127.0.0.1:9990/metrics.
That way you don't expose the whole admin panel, but only the metrics part.
We have forwarded the port 8081 in our WLAN router for a particular Static IP address. After that, tomcat is taking too much of time to start. Approximately, it is taking 56149 ms to run. Why it's happening so? Do I need to add any exceptions in my firewall? Is there any way to start it faster.
Any idea would be greatly appreciable!!!
Is it possible to use port 80 for non http traffic ? For example I'm making a small script that will communicate with a friends computer through the internet, however they must port forward it to get past the router. Is there a problem with using port 80 in the script so it will be let through automatically ? Is there some part of this i don't understand that will not let non http data through ? Please explain :)
there is no problem doing that. in fact, skype's default behaviour is to use port 80 and port 443 to transport voice!
There are a lot of ISPs that actually block port 80, so you might want to try a different port if you are having a problem (still needs to be forwarded)
The firewall on the computer also needs to be set to allow the incoming traffic.
This will work fine, but your friend may still need to setup port forwarding
If your friend's PC is the one listening on Port 80, he will need to setup port forwarding. Otherwise, how would the router/NAT know which computer in the house to bridge the connection to?
But if your friend's PC is the one making the outbound connection, then likely no port forwarding is needed at all on his end.
In other words, port forwarding (for TCP) is only for inbound connections. The router/NAT will automatically setup a port mapping scheme for outbound connections (as it does it with all web traffic).
Given a device with an open TCP port on a non priviliged and not widely used port number from which I assume a known service like Telnet, SMTP or HTTP is running there and not on its standard port, e.g. a XMPP service on port 12345 whether this makes sense or not: How do I find out which service runs there?
You can try to scan with nmap tool.
