I am trying to connect spyder, running on local_machine (macOS), to a remote kernel running on compute_server (a compute node of a cluster). The compute node is not directly accessible via the internet, I can only access the cluster via login_server.
I try the following:
On compute_server I do:
python -m spyder_kernels.console
To connect another client to this kernel, use:
--existing kernel-20351.json
I copy this json file to the appropriate place on local_machine. It contains the text:
"shell_port": 46540,
"iopub_port": 39268,
"stdin_port": 40704,
"control_port": 42637,
"hb_port": 46887,
I create an ssh tunnel through login_server. On local_machine I do:
ssh -L46540:compute_server:46540 -L39268:compute_server:39268 -L40704:compute_server:40704 -L42637:compute_server:42637 -L46887:compute_server:46887 me#login_server
I start spyder on local_machine, ask it to connect to an existing kernel, enter the name of the json file, check the 'This is a remote kernel' box, enter me#login_server for Host name. I have ssh keys set up for login to login_server already.
The connection hangs. If I start the spyder kernel on login_server and omit Step 2 then it works fine, but I can't do heavy computation on login_server, I do have to work on compute_server.
Any ideas?
I believe it should work if you connect Spyder to your localhost. So at the 'This is a remote kernel' box, enter localhost for the Host name. And enter the relevant port(!).
(And add your username and password for compute_server.)

I am looking to setup AzerothCore for LAN only use.
I am using an ESXi install with an Ubuntu 20.4.3 instance with latest Docker and Portainer for management. I am able to walk through the install process and it works great.
I switched the realmlist in the database to the LAN IP via HeidiSQL, setting both address and localaddress to LAN IP. I have tried just address and localaddress, leaving the other at 127.0.0.1.
I am using a fresh client install and set realmlist there too. I have tried both the dns and the IP, currently set to LAN IP.
I have not touched the compose file or modified authserver or worldserver config files. I am not certain where to look or what to change.
I am able to login with the ID I created all the way to see the Realm, which I select and hit enter. After a short pause the client screen returns to the realm selection screen. Not knowing the backend, I am not sure what is missing now.
Unable to access localhost Jenkins from another computer in the same network. These are the steps I did
1) I pinged the ip address of the computer from another computer and it is successful
2) I change the Jenkins URL in the config to - http://[IP of the machine:8080]
3) Turned off the firewall.
However I am not able to access this url from the same computer or another computer - http://[IP of the machine:8080]
Any time would be appreciated. Followed all the steps, not sure if i need to use a service like xamp or mamp
i also did ifconfig and this is what i got. My jenkins port is running on :8080 and i dont know what url to add to my jenkins so i can access it from other network within the same computer
Also what other steps i need to do, do i need to open the port from somwhere?
For Instance, your IP of Jenkins master is 192.169.x.x.
Open the Port 8080 via firewall and then change the URL of jenkins from "Manage Jenkins >>Config Sys >> Jenkins Location>" to "http://192.169.x.x:8080"
Now you can access it from other machine on same network domain.Just have to hit the url http://192.169.x.x:8080
You can now create different users with different privileges for the same.
You can find it under Manage Jenkins >> Manage Users >> Create Users.
I'm trying to create a Test automation Pipeline to run my selenium scripts, I installed Jenkins in windows Remote Server 2012. Used following cmd($ java -jar jenkins.war) to start jenkins. It is working fine in Remote server with url:http://localhost:8080/
But when I'm trying to access it outside Remote server(my local machine) it is not working. am getting error message "This site can’t be reached"
My local laptop and Remote server is under the same proxy org network.
Can someone help how to resolve this issue , so that other folks can access it and run jobs when required from their laptops
Thanks in advance
Access Windows Firewall.
Add an inbound rule to allow port 8080 and
try accessing the url from any machine in the network.
you could allow/restrict access to all IPs, range of IPs or allow all. But to nullify the issue and confirm if its an issue with whitelisting IPs, I'd first allow access from all IPs with the wildcard *
for Debugging if its a port whitelisting issue, you could also telnet from the machine that you are trying to access this machine -
try
telnet remote machines IP Port
note: do not use a colon for port input just use a space
I have installed Jenkins in Windows server 2012 64-bit machine and want to make it available in internal network.
I have added --httpListenAddress to 0.0.0.0 and restarted Jenkins and tried to access it with http://hostname:8080 but no page shows up(though It showing Jenkins icon in URL bar). However http://localhost:8080 works fine.
Further I checked the firewall inbound rule for the Jenkins but seems it has no issues.
I tried to catch the listening ports with "netstat -aon | find /i "8080" and found <host ip address>:8080 FIN_WAIT_2 which sign towards that the request is stuck(May be I am wrong).
I am clueless what exactly is blocking to use hostname with jenkins. Please share your solution if you already fixed this issue.
You might try adding a Windows Firewall rule. Go to Windows Firewall, Advanced Configuration, Inbound Rules rule and create an Allow rule for the specific version of java.exe you have installed.
This worked for us with the drawback that every time you upgrade Java, you must also modify the firewall rule. This is because Java creates a new subfolder for every version. We've tried using %JAVA_HOME% in firewall rules but it doesn't seem to work. We were on Windows Server 2012R2 at the time.

On the server open a new command prompt and type
ipconfig
You should get a list of ips. Open a browser and type each up followed by 8080 for e.g.
http://202.123.2.1:8080
If Jenkins opens up, from another computer ping the ip and see if you can get a ping reply
ping 202.123.2.1
If you get a ping reply, you can access jenkins from any pc on the network by typing in the ip and port number.
Now to get to the hostname,you need to edit your host file
c:\Windows\System32\Drivers\etc\hosts
Type in the ip followed by the hostname
202.123.2.1 jenkins
If you can't get through, you need to open port 8080. See https://www.vultr.com/docs/how-to-open-a-port-in-windows-firewall-on-windows-server-2012
You cannot access from outside the machine because Jenkins Service does not have credentials to use that machine, only from localhost is accessible.
This is how to enter the credentials in Jenkins service.
In the Windows search bar, type services then enter.
Then scroll down to Jenkins and double-click on it.
In Jenkins Properties, select the tab "Log On".
Select Check box "This account"
Update your username and password.
Voila! Now Jenkins web can connect to the Jenkins machine via Jenkins service.
Possible to Change Jenkins URL? : http://localhost:8080
Currently I have jenkins setup on a virtual machine.
Is it possible to setup Jenkins on a URL which is more is accessible for other users?
For example I dont want other users to access test results by connecting to the Virtual machine instead I want them to access a URL from their own device in turn enabling them to login and see test results via jenkins.
thanks for you help
Let's say IP of your virtual machine is 192.168.x.x.
Open the Port 8080 via firewall and then change the URL of jenkins from
"Manage Jenkins >>Config Sys >> Jenkins Location>" to "http://192.168.x.x:8080"
Now you can access it from other machine on same network domain.Just have to hit the url http://192.168.x.x:8080
You can now create different users with different privileges for the same.
You can find it under Manage Jenkins >> Manage Users >> Create Users.
It is related to networking. The machines should be on the same network, so they can talk to each other (unless you have public IP).
The ONLY rule to give access is, that machines can talk to each other (of course, in their language, 0's & 1's).
I suggest following things to do to share the URL:
Ask the users to connect to the same network that your machine is in.
Verify whether they are able to PING your machine IP (get it from ipconfig command for windows - router assigns IP for your machine, that starts with 192.168 or 10.10). command example: ping 10.10.1.10
If any issues in Ping, it might be Windows Firewall or Anti-virus which might be blocking, so allow the IPs in your firewall so they can access your machine.
Then ask them to access Jenkins using the following URL http://[IP of your machine:8080]
We want the Jenkins web interface to be accessible from anywhere (not
just on the local machine), so we’re going to open up the config file:
sudo nano /usr/local/opt/jenkins-lts/homebrew.mxcl.jenkins-lts.plist
Find this line:
<string>--httpListenAddress=127.0.0.1</string>
And change it to:
<string>--httpListenAddress=0.0.0.0</string>
