F5 Web GUI cannot be access - f5

We have a pair of F5 running in HA (Active/Standby Mode). the problem is the F5 node 2 some interface (selfIP) can be ping, but cannot be SSH or connect via HTTPS. All are fine on F5 node 1 (primary). All the configure are in sync. i have try reboot them all, but same case

you need to make sure the Self-IPs you are connecting to are configured to allow those ports, as self-IP configuration is device specific and is not synced.

Jenkins not accessible with http://<hostname>:8080 in Windows server 2012

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.

Jenkins Server - Issues with setting URL

I am trying to set up an internal Jenkins server for our QA team and facing some issues with the server URL. This is inside a corporate network and all sort of firewall and proxy settings are in place, however we need to access the server only with in our internal network. This server runs from a Mac Mini. I was able to install and access the server without any issues using localhost:8080.
I tried to set a custom URL (something like testjenkins.local:8080)under the Manage Jenkins option and never was able to access the server. The only option worked for me is with the IP address (IP:8080). I was able to access the server from other machines in the network using this URL.
The real problem with the above setup is that the machine IP changes(I am not able to make it static), and hence wont be able to get an always working URL.
Highly appreciate if any one guide me in the wright direction.
Given you have a dynamic IP on your server, a good alternative would be using ngrok. Ngrok can expose the port 8080 of that server to the internet via secure tunnels, and you can access it via an URL, so changes in the IP won't affect it.
However, ngrok exposes the server to the whole Internet. To make it accessible only for your team you can add authentication in both ngrok tunnel and Jenkins server (would it work for you?).

testing mobile apps at home (IIS hosted)

I am not sure what to look for with the current problem and I appreciate your suggestions.
Basically, all I want to do is locally host a web application on IIS and access it from my mobile browser.
My web application is hosted on the local IIS and works fine on the main machine. I can use my computer name, internal ip or external ip instead of localhost to connect to the app from the main computer. But when I go to another computer (which I can see and exchange files with) connected to the same network I cannot access the web application on the main machine. I tried ip and machine name.
At work, we are connected to a Domain and I tried the same thing with the work computer. When I write my computer name or it's ip, I can access hosted app from another computer.
So the question is, do I have to have a domain for this capability and if so, Is it possible to create a local domain at a home network? What do I need to search for to get this working? Is WAMP a must?
Apparently opening the outbound/inbound port 80 from windows firewall is enough

How to administer computer when no inbound connection is possible?

I have to periodically administer my parent's Linux computer, because they are too old to understand how to do this themselves. Computer is in the remote location. I always used ssh through the port forwarding on the router. However, their provider recently removed the ability to make any inbound connection and my ssh doesn't connect any more.
My question is: what is the next best way to administer it?
I know that VPN can possibly be used. I can (maybe) set up VPN network with this computer.
Also I can make it try to connect with ssh to my home computer on a particular port for ex. every 15 minutes, establishing the port forwarding back to it. Custom shell script should be used for this.
But what are the alternatives?
Any other, nicer way to be able to connect to this Linux machine from outside?
Similar to your suggestion: get your parents to run a script (all they would have to do is double click something) which ssh's to your computer, and then run back on that?

Can you please give me a Step by Step instructions to set up TFS in such a way that my team can access it from anywhere in the world?

Basically, Me and my team are working in the geographically dispersed location,My teammate is is in USA and I'm in India. I've Installed the TFS on my development machine (Windows Vista) and I want to my team to access the same exact project which i'm working on anytime,anywhere.
We dont have any funds to buy a hosting account or We dont have funds to create a VPN Account from the internet (my ISP doesnt provide me one...awwww).
I don't run TFS, but this is more of an IT question than a TFS-specific one, I think.
My coworker showed me a trick that precludes the need for VPN, but is still secure. You'll need to set up your firewall to route traffic from one of your WAN IPs to an internal server that allows SSH access. These steps will be router and internal network-dependent.
Then download and install PuTTY or PortaPuTTY. Set up a profile that points to your public WAN IP and SSH port, and also add SSH tunneling to route a port on your local computer to the TFS server IP and port.
Let's say you choose a local port of 12345 and your internal TFS server IP is 192.168.0.100 and the TFS port is 1234. When you connect to TFS with PuTTY, instead of specifying its IP, you'll connect via localhost:12345.
