Trying to connect to localhost on my development machine with my iPad using wifi.
The webserver integrated in Visual studio.
Using ip number I get from ipconfig.
192.168.1.84:1144
I'm receiving http 400 error.
I've added port 1144 as TCP/IP port on firewall.
Anybody knows what I'm doing wrong?
does your machine have a static IP? with DHCP enabled, the ip of your machine keeps changing every now and then, so it might be the case that the address provided is no longer available!!
disconnect and reconnect to your network, then run ipconfig again and check if the IP has changed, if it has, then DHCP is enabled...

I have a bit of a bizarre problem. I have a Hyper-V VM and I cannot connect to it via IP address on the host computer.
I intend to use it as an SQL server to host a database for a website while I test it, and the first step I can see in this endeavour is to make sure the IP addresses work externally.
Other PCs on the LAN appear to be able to connect just fine via the IP address on Remote Desktop. I cannot do so. I also cannot connect through SQL Management Studio (named pipes or TCP/IP). Although named pipes gives an error relating to being denied access as opposed to IPs which are just not found.
I have tried pinging both ways:
VM => Host : Always gives a "Destination Host Unreachable" error
Host => VM: Always gives a "Request Timed Out" error
As for netstat -a -n, I can see that the VM is listening to 3389 (default Hyper V port, which makes sense).
Regarding Firewalls, all have been turned off on all machines. I can tell that the firewall is not the issue.
If you need any more information to help me to diagnose and treat the problem, please ask me as I would like to get this sorted as quickly as possible.
Thanks a lot in advance.
Which windows server version do you use?
Windows Server 2016 blocks insecure RDP connections (https://support.microsoft.com/en-us/help/4295591/credssp-encryption-oracle-remediation-error-when-to-rdp-to-azure-vm).
Since RDP uses CredSSP you have to install the current Windows Patches.
Do you can ping the DNS server by IP address from your VM?
Is ICMP (ICMP = the thing you need for ping) on your host enabled?
Here is a Checklist for ICMP:

Solved,
Just switched to another physical computer and it was fine.
I have a websocket server running on a pc connected to the pc through a switch.
When I make a websocket client in the HoloLens with the IP of the server it doesn't connect. How come? I cannot ping the HoloLens emulator from the pc with the server but I can ping the pc running the emulator.
By default all interactions with the emulator are done through a 169.254.xxx.xxx address. This address is not externally routable. If you go to the networking menu option in the web portal for the emulator you should see two network adapters, one is the 169.254.xxx.xxx address and another is an address assigned via dhcp. My guess is that you don't have a second adapter and need to fix that in your Hyper V configuration for the emulator. If you do have that second adapter pinging that address will not work, because HoloLens does not run and ICMP server to respond to pings. A better test is to open Internet Explorer in the emulator and attempt to go to a valid web server address on your network. Here is what my settings look like as an example:
I am having some trouble allowing my 2wire router (provided by AT&T to forward certain ports.
I have a raspberry pi running subsonic (a music server) and I would like to access it from the outside internet. I have configured the pi with a static LAN IP address and have opened the specified ports (4040 and 80) on both TCP and UDP. I have also confirmed the service is active and is listening on the specified ports via netstat.
When I attempt to connect, however, from my WAN IP I am confronted with a connection refused dialog. Checking the firewall logs on my router, I see this message
IN=br1 MAC=--:--:--:--:--:-- SRC=(my computer IP) DST=(My WAN IP) LEN=40 TTL=240 PROTO=TCP DPT=5060 Unknown inbound session stopped
It appears that my firewall is still blocking the external connection. What strikes me as odd is, although I am unable to connect I can still see that the port is open from an outside port scanner. Using the service provided from http://www.yougetsignal.com/tools/open-ports/ I have confirmed that my IP has port 4040 to be open.
Once again, I have confirmed that the service is indeed listening on the raspberry pi, setup a static LAN address and created the protocol for both TCP and UDP....
Any help on this matter would be greatly appreciated.
Thanks in advance!
Ok so for whatever reason it was working all along. Apparently it was just getting confused by me trying to connect to my own router. I confirmed this by connecting to the server via 4G on my phone.
Dumb mistake by me.
I have got chef-server installed on a centos machine.
Everything is working as expected except that I cannot access the chef-server web interface from another machine on my local network.
I can access the web interface from the centos machine itself:
telnet mychefserver.local 4000
Connected
If I do the same from my machine I have got:
telnet: Unable to connect to remote host: No route to host
I can successfully ping mychefserver.local from my machine
Any idea how to configure nginx with chef-server to access the chef-server from the network?
Since Chef Server 10, the web interface uses normal HTTPS (TCP 443), it only listens on the high ports locally, and nginx proxies as needed to the different backend services. I would try with a normal web browser as telnet isn't exactly great at error messages. Normally I would expect that to mean telnet is getting TCP transmission errors, but maybe it is just confused? If it is really a TCP transmit error then more likely the internal DNS is having issues. .local often means mDNS which has uneven support in some places, I would try an actual IP address to be sure.
My issue was iptables.
I stopped iptables and I can access the chef-server from my local network again.
I'm working on a website for a friend, developing using Eclipse/Tomcat. I'm running it locally and trying to open it via my internet port IP address, but I can't get it to work. The computer I am running it from is connected to a router, so it is running off of 192.168.1.4, and http://192.168.1.4:8080/Mobile_Site/index.jsp works. However when I try and open it via my internet port IP, http://67.xxx.244.xx:8080/Mobile_Site/index.jsp it doesn't find it from any device, even outside my local network. Is there a way to send the link when running locally when connected to a router?
You have to configure your router port forwarding (or virtual servers depending on the router) to forward TCP connections from 67.xxx.244.xx:NNNN to 192.168.1.4:8080.
Then you give the 67.xxx.244.xx:NNNN address to your friend.
Note: NNNN at your router doesn't need to be 8080, as long as the port forwarding is set properly.
