Enable and Configure proxy using CMD

Enable and Configure proxy using CMD - command-line

seeking your support to create a bat (CMD) file that can be used by standard user and administrators that can configure the proxy settings and the port number to be as shown below
proxy : 10.10.10.10 port number : 1111 and
check mark bypass proxy settings and
add xxx.xxx.xxx.xxx to the exceptions
thank you in advance

On Windows, one can modify the network settings via commandline by using the netsh command.
For example, changing the proxy works as follows:
netsh winhttp set proxy myproxy
or in your scenario:
netsh winhttp set proxy 10.10.10.10:1111
Have a look at the detailed documentation here, and at this superuser thread

Returning and editing proxy settings (Internet Options) through command prompt

I am wanting to see and edit the proxy settings that are found in the internet options of windows. I have tried: netsh winhttp show proxy but that returns nothing when there is a proxy in the internet options. If I use reg query "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings" | findstr ProxyServer AutoConfigURL then it will spit out the current proxy and port in the internet options which is what I need. Is there a way to return and/or add exceptions to the proxy? In the internet options when clicking "Advanced" you can enter exceptions separated by semicolons(;). Is there a way to do this through the command line? Thank you for any help!

WinRM error while connecting to remote server using powershell [duplicate]

I successfully enabled PSRemoting on my Server 2008 R2.
I'm able to do a remote-pssession from within the same network using the hostname as target.
I'm failing when I try to use the IP-Address as target from any computer (within the network or from another network (for example via VPN)).
I want to be able to use remoting through my VPN connection where I have to use the IP-Address since the hostname can't be resolved.
I don't want to add names into my hosts-file because there are a few other servers at our clients' that have the same dns-name and I don't want to remove and insert the name-ip-address-association again and again.
I hope someone can tell me how to allow the psremoting-target to be called via IP.
Edit: To be more specific, I want to be able to run this:
Enter-PSSession -Computername 192.168.123.123 -credentials $cred
But I'm only able to run that command if I pass a hostname to "-Computername"
Edit2:
I'm getting following errormessage when I try to login using the ip instead of the hostname (from the internal network):
Enter-PSSession : Connecting to remote server failed with the following error message : The WinRM client cannot process
the request. Default authentication may be used with an IP address under the following conditions: the transport is HT
TPS or the destination is in the TrustedHosts list, and explicit credentials are provided. Use winrm.cmd to configure T
rustedHosts. Note that computers in the TrustedHosts list might not be authenticated. For more information on how to se
t TrustedHosts run the following command: winrm help config. For more information, see the about_Remote_Troubleshooting
Help topic.
Edit3:
I know about the trusted-hosts setting of WSMan, but that doesn't seem to be the problem. It is already set to "*" (I did that right after enabling remoting), but I still can't connect to that server using the ip as target-computername, but I'm able to connect using the hostname as target-computername. Seems like there's something like the binding in IIS that prevents the listener to listen on requests that target the ip-number instead of the hostname. But IIS isn't installed. I don't know where to look for such a setting.
Update 2011-07-12:
Okay, I think that trustedhosts-setting is not the problem because I CAN connect from our DC via hostname but not if I use the ip-address of the destination for the computer-param.
I think, the problem must be the listener. Maybe the listener takes no requests that were targeted to the destination-ip instead of the destination-hostname. But I don't know how to change that.

The error message is giving you most of what you need. This isn't just about the TrustedHosts list; it's saying that in order to use an IP address with the default authentication scheme, you have to ALSO be using HTTPS (which isn't configured by default) and provide explicit credentials. I can tell you're at least not using SSL, because you didn't use the -UseSSL switch.
Note that SSL/HTTPS is not configured by default - that's an extra step you'll have to take. You can't just add -UseSSL.
The default authentication mechanism is Kerberos, and it wants to see real host names as they appear in AD. Not IP addresses, not DNS CNAME nicknames. Some folks will enable Basic authentication, which is less picky - but you should also set up HTTPS since you'd otherwise pass credentials in cleartext. Enable-PSRemoting only sets up HTTP.
Adding names to your hosts file won't work. This isn't an issue of name resolution; it's about how the mutual authentication between computers is carried out.
Additionally, if the two computers involved in this connection aren't in the same AD domain, the default authentication mechanism won't work. Read "help about_remote_troubleshooting" for information on configuring non-domain and cross-domain authentication.
From the docs at http://technet.microsoft.com/en-us/library/dd347642.aspx
HOW TO USE AN IP ADDRESS IN A REMOTE COMMAND
-----------------------------------------------------
ERROR: The WinRM client cannot process the request. If the
authentication scheme is different from Kerberos, or if the client
computer is not joined to a domain, then HTTPS transport must be used
or the destination machine must be added to the TrustedHosts
configuration setting.
The ComputerName parameters of the New-PSSession, Enter-PSSession and
Invoke-Command cmdlets accept an IP address as a valid value. However,
because Kerberos authentication does not support IP addresses, NTLM
authentication is used by default whenever you specify an IP address.
When using NTLM authentication, the following procedure is required
for remoting.
1. Configure the computer for HTTPS transport or add the IP addresses
of the remote computers to the TrustedHosts list on the local
computer.
For instructions, see "How to Add a Computer to the TrustedHosts
List" below.
2. Use the Credential parameter in all remote commands.
This is required even when you are submitting the credentials
of the current user.

Try doing this:
Set-Item WSMan:\localhost\Client\TrustedHosts -Value "*" -Force

I test your assertion in my infrastructure the IP address is not the problem the following works for me :
PS C:\Users\JPB> hostname
JPBCOMPUTER
PS C:\Users\JPB> Enter-PSSession -ComputerName 192.168.183.100 -Credential $cred
[192.168.183.100]: PS C:\Users\jpb\Documents>
[192.168.183.100]: PS C:\Users\jpb\Documents> hostname

If you try to work accross a VPN you'd better have to have a look to the firewall settings on the way to your server. Installation and Configuration for Windows Remote Management can help you. The TCP port WinRM is waiting on are :
WinRM 1.1 and earlier: The default HTTP port is 80.
WinRM 2.0: The default HTTP port is 5985.
Edited : According to your error can you test this on youclient computer :
Set-Item WSMan:\localhost\Client\TrustedHosts *

The guys have given the simple solution, which will do be you should have a look at the help - it's good, looks like a lot in one go but it's actually quick to read:
get-help about_Remote_Troubleshooting | more

On your machine* run 'Set-Item WSMan:\localhost\Client\TrustedHosts -Value "$ipaddress"
*Machine from where you are running PSSession

On Windows 10 it is important to make sure the WinRM Service is running to invoke the
command
* Set-Item wsman:\localhost\Client\TrustedHosts -value '*' -Force *

For those of you who don't care about following arbitrary restriction imposed by Microsoft you can simply add a host file entry to the IP of the server your attempting to connect to rather then use that instead of the IP to bypass this restriction:
Enter-PSSession -Computername NameOfComputerIveAddedToMyHostFile -credentials $cred

Please try the following on the client:
Run the following command to restore the listener configuration:
winrm invoke Restore winrm/Config
Run the following command to perform a default configuration of the Windows Remote Management service and its listener:
winrm quickconfig
After you configured winrm again, make sure host is trusted:
Set-Item wsman:\localhost\Client\TrustedHosts -value "$ipaddress" -Force
Try remote connect again
Reference
Configure winrm for HTTPS

I spend a great amount of time and finally got the solution. Following are the steps to do fix this -
Go to Control Panel\All Control Panel Items\Network and Sharing Center\Advanced sharing settings in control panel
Make sure machine discovery in domain and guest is ON.
Open powershell in administrator mode on client machine and run winrm quickconfig and winrm set winrm/config/client '#{TrustedHosts="*"}'

As Don touched on this, here is more info

Configure and listen successfully using WinRM in powershell

I'm testing WinRM connection using Command Prompt on my local and remote machine and my question is devided into two parts.
PART I
I tested TCP/IP connectivity by using ping command to ping : IP Address of local computer and remote computer, default gateway and DNS Server and it runs perfectly on both local and remote computer.
But when testing using WinRM commands, I used this command to locate listeners and addresses
winrm e winrm/config/listener
It gives me this output for my local machine
Listener
Address = *
Transport = HTTP
Port = 5985
Hostname
Enabled = true
URLPrefix = wsman
CertificateThumbprint
ListeningOn =<IP Address>,127.0.0.1, ::1,fe80::100:7f:fffe%13,fe80::803:5e43:50ef:c50%11
But the same command when I run on remote machine gives me an output with everything else the same, except
Listener[Source="GPO"]
.
.
.
ListeningOn=null
I want to configure it to make it listen correctly.
PART II
And when I run these commands one by one on my remote machine
winrm id -r:<machine name>
winrm get winrm/config -r:<machine name>
winrm get wmicimv2/Win32_Service?Name = WinRM -r:<machine name>
It gives a WSMan Fault with an error message as :
The client cannot connect to the destination specified in the request. Verify
that the service on the destination is running and is accepting requests.Consult
the logs and documentation for WS-Management service running on the destination,
most commonly IIs or WinRM. If the destination is the WinRM service, run the
following command on the destination to analyse and configure the WinRM service:
"winrm quickconfig".
Whereas, same commands when I run on my local machine run correctly.
winrm id
winrm get winrm/config
winrm get wmicimv2/Win32_Service?Name = WinRM
At most, all the problems I'm facing is on my remote machine.
What is causing this to happen and how can I configure it to listen and connect successfully?
Thank You.
Part II, I am now able to run these on one of my other remote machines with correct output.
I made some changes in this particular remote machine for which I had posted the question and so, it wouldn't run these commands until I fix the part I but besides that if nothing has been altered it will run just like it does on my other remote machines.
I would still appreciate if someone could help me with part I in which I have to get rid of
Listener[Source=GPO]
..
.
ListeningOn=null
when I run the command
winrm e winrm/config/listener
because this is what is causing issues but I'm not sure how to disable/remove Group Policy Settings.

To determine which group policy is configuring your WinRM you can run the following from an administrative command prompt:
gpresult /h result.html & result.html
In the displayed result, locate Windows Components/Windows Remote Management (WinRM)/WinRM Service. The Winning GPO is where you can enable/disable GPO settings. Use GPMC (Group Policy Management Console) to manage the Group Policy.
ListeningOn=null appears when an administrator has incorrectly configured the Group Policy IPv4 filter setting in Allow automatic configuration of listeners usually with an IP or network that does not exist on the affected Server.

To reset IP addresses (ListeningOn), you probably need to re-create the listener (remove the old HTTP listener and create a new one). Please find the example below.
In PowerShell:
Remove-WSManInstance winrm/config/Listener -SelectorSet #{Address="*";Transport="http"}
New-WSManInstance winrm/config/Listener -SelectorSet #{Address="*";Transport="http"}
Here is the syntax for the specific IP address to bind:
New-WSManInstance winrm/config/Listener -SelectorSet #{Address="IP:192.168.100.2";Transport="http"}
In Command Prompt:
winrm delete winrm/config/Listener?Address=*+Transport=HTTP
winrm create winrm/config/Listener?Address=*+Transport=HTTP
Further reading:
Three ways to configure WinRM listeners.
The Windows Remote Manager (WinRM) service does not start.
Related question: Allow PowerShell remoting only from one address.

I had the same issue and found that when the GPO Setting: Allow remote server management through WinRM had an IPv4 filter set to the IP address of my jumphost the winrm e winrm/config/listener command generated the ListeningOn=null issue.
I solved this by setting the Filter to * and sorting the permissions on firewall level instead.

I solved this changing a GPO, exactly as answered Neossian (sorry, no reputation to just add a comment). But "IPv4 filter" must not be empty, nor accepts CIDR notation (that was my huge mistake). As already said by Craneum, uses "*" for listen on any interface or some range of IP addresses your local network devices are connected (as "192.168.0.1-192.168.0.254" or something like that).
DO NOT USE "192.168.0.0/24" notation. Yes, the help section is very clear on that, yet I used the wrong notation.

The thing is that the IP Range you are entering is not the range that has access to the system but defines the IP range that can be used as the WinRM interface by the system. Means you have to specify a range of IP addresses which includes all the client IPs the GPO is affecting.

Ensure that you have a filter (IPv4 and/or IPv6) defined in the "Allow remote server management through WinRM" under [Computer Configuration]/[Policies]/[Administrative Templates]/[Windows Components]/[Windows Remote Management (WinRM)]/[WinRM Service].
I would suggest a filter of "*" for both IPv4 and IPv6 unless you know what you want to filter.

How to access JBOSS Restful web service using IP and Port

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

Powershell remoting with ip-address as target

Try doing this:
Set-Item WSMan:\localhost\Client\TrustedHosts -Value "*" -Force

JPBCOMPUTER
PS C:\Users\JPB> Enter-PSSession -ComputerName 192.168.183.100 -Credential $cred
[192.168.183.100]: PS C:\Users\jpb\Documents>
