I am trying to run JBoss(5.1) on remote system connecting it using RDC. Which ever port I try, it's says already in use and throwing java.net.BindException Cannot assign requested address: JVM_Bind
I have tried to change the port using jboss service binding configuration located at below path:
jboss\server\Server_Instance\conf\bindingservice.beans\META-INF\bindings-jboss-beans.xml
I have tried various options like ports-01, ports-02 ,ports-03 and then customizing the default port configurations as well with No luck.
I am just wondering how it is possible that it's not allowing any port whichever I try. One thing I would like to let you know here is that the remote system has 3 different logins and all of the users are using the system.
Appreciated if you can provide me any assistance please.
You can pass the -b ${IPofMachine} to bind to an IP. This will also make it externally accessible. You can do 0.0.0.0 which will bind to all available IP's

Trying to configure Live Server to properly launch and connect to web pages on my local machine in VSCode .However, I seem unable to set the port I want to run live server on. When I accept the default port (chosen by the extension itself) I get ERR_UNSAFE_PORT from both Chrom and Firefox.
I have tried changing the settings, but its seems to be ignoring anything I put in there. Can someone please advise ?
Here is a screenshot of where I am trying to set the port..
Thanks..
P.S It does not matter what value I use for the port (2000 here just as an example.) Whatever you put in is ignored. tried various,, 8080 etc..

May local config overrides the global config？
I have some issue to configurate Ngrok.
I have installed the Ngrok on linux CentOS server dedicated (IP 192.168.1.124), it works correctly the tunneling is ok.
My question is: how i can reach the web page on 127.0.0.1:4040 in order to check the traffic on my Ngrok server?
The web interface page is only accessible on the server where ngrok is running, but if this is a linux minimal server (without gui and any type of browser) I can't see it.
is there a way to make it accessible also in LAN?
e.g. I have another client that can reach the IP where ngrok is running but if i put on web browser http:\192.168.1.124:4040 nothing is showing.
I see from netstat that this port is not listening so isn't a firewall problem or other.
Is possible to change config of Ngrok? otherwise are there other possibilities ? do i have to use a reverse proxy or something like?
Any ideas?
thanks for your help,
Luca
Locate your ngrok's config file:
$ ngrok config check
Valid configuration file at /home/youruser/.config/ngrok/ngrok.yml
Add to the config file the following line:
web_addr: 192.168.1.124:4040
In case you want to expose it to all interfaces, you can replace that value with 0.0.0.0:4040
Sorry for the basic question but im a complete noob on those matters.
I have a cloud server where i run a jup[yter notebook server, which normally is run on port 8888.
However when i try to connect to it from work, it doesnt work, which i suspect is due to the firewall.
I can connect from work to a regular ssh session through port 22 or 443.
However the jupyter notebook refuses to be run on those ports, probably because they are allocated already.
I tried to run PortQry to get the open ports on my work server (which is windows) and it reurned port 50248. I tried to have my jupyter server to listen on that one but it didnt work.
I also tried to scan the open port of my work server, but i received a warning from AWS! And the few ports that were returned as seemingly opened didnt work either when i set up my jupyter notebook to listen on them.
I would like to understand:
On my own server: How can i identify which port the jupyter server program can listen on?
On my work machine: How can i identify which one of my own server port would be let through the firewall of my work?
You need to use SSH local port forwarding.
https://help.ubuntu.com/community/SSH/OpenSSH/PortForwarding
You will open a SSH connection to your server but a local port, lets say 4444, will connect over the SSH connection and resolve to 8888 on the remote server.
With this you'd be able to open a browser locally and go to localhost:4444 and it would resolve to your remote hosted site. The command for this locally would be something like -
ssh -L 4444:localhost:8080 yourremoteserveraddress
An alternative option would be to use a SOCKS proxy via dynamic forwarding but this would involve needing to reconfigure your browser.
Always keep in mind any company policies around this type of thing. Even though 22 and 443 are open to the internet, use of them in this manner may break a policy and there is always the possibility of the company using a MITM proxy to monitor for this type of usage, specifically on 443.
I'm trying to deploy my camel app which on start is creating a cxfrs endpoint. The url is like this: http://localhost:9876 . When I try to hit this one on a rest client or anywhere within my machine it works. But when I try to access it using my phone or other external devices, I'm not able to connect.
Am I missing something?
TIA
Using localhost will mean it is only accessible to your local machine, using 0.0.0.0 instead should make it publicly accessible.
0.0.0.0 should bind all available network interface on your remote machine, but from your description, somehow it only bind to localhost|127.0.0.1 so only accessible from local machine, could you use
http://external.ip.address:9876/foo/FooService
instead to see if it helps?
Also, you can try to access other network service(for example start a tomcat on remote machine and see if you can access it from your local machine) from that remote machine to see if it works, this can determine if your DNS correct or if there's really no firewall between them.
I created a test JBOSS web service and there is only one test method in it. I access this using http://localhost:8070/MyWebService/MyRESTApplication
and it shows the result from the web service. I tried this in both Eclipse and Browser and it works.
But when i want to access this web service using IP address of my system then it shows ERROR message that Page cannot be displayed (in fact browser is not able to find this web service).
I want to access like this http://IPaddress:8070/MyWebService/MyRESTApplication
what should i do so that i can access it using my IP from some computer
You have to start JBoss using :
./run.sh -b [your_IPaddress]
On windows:
start run.bat -b 0.0.0.0
This will tell it to start and bind to all network interfaces. You can also replace 0.0.0.0 with your actual IP if you only want it to bind to that network interface.
I find it easier for debugging to have it come up on all network interfaces because this will work when you are running a virtual machine to debug something like Internet Explorer.
Open your server setting in Eclipse and set Host name as your IP address or 0.0.0.0
