Windows Server nudi mnoštvo alata za administratore u slučaju da se aplikacija ili računalo ne mogu spojiti na određeni port ili IP poslužitelja. Jedna stvar koja se odmah pojavljuje je korištenje alata za rješavanje DNS -a i drugih problema s mrežom, ali ako volite koristiti PowerShell , postoji briljantna naredba Test-NetConnection koju možete koristiti.

Rješavanje problema s mrežnim^{(Troubleshoot Network)} povezivanjem putem PowerShell -a^(PowerShell)

Možete koristiti Test-NetConnection cmdlet da biste saznali dijagnostičke informacije za vezu. Uključuje podršku za Ping test, TCP test, praćenje^{( route tracing)} rute i dijagnostiku odabira rute.

Ovisno o opcijama koje se koriste, izlaz će se sastojati od informacija kao što su  ComputerName , RemoteAddress , SelectedSourceAddress , OutgoingInterfaceIndex , SelectedNetRoute i još mnogo toga.

Ovdje je popis podržanih parametara

• Zajednički TCP port: Određuje tipični broj TCP porta usluge
• ComputerName: Određuje naziv sustava naziva domene^{( Domain Name System)} ( DNS ) ili IP adresu ciljnog računala.
• ConstrainInterface: Određuje ograničenje sučelja koje će se koristiti za dijagnostiku rute.
• ConstrainSourceAddress: Određuje ograničenje izvorne adrese koje će se koristiti za dijagnostiku rute.
• DiagnoseRouting: Označava da se dijagnostika rute izvodi za izlaz informacija o odabiru rute i izvorne adrese za udaljeni host.
• Hops: Određuje broj skokova koje treba prijeći u naredbi traceroute.
• InformationLevel: Određuje razinu informacija Detaljno ili Tiho
• Port: Određuje broj TCP porta na udaljenom računalu.
• TraceRoute: Označava da se Tracert pokreće radi testiranja povezanosti s udaljenim hostom.

Popis primjera naredbi

Evo nekoliko primjera naredbi koje možete isprobati na svom računalu. Neke od ovih naredbi trebat će administratorske povlastice, stoga svakako pokrenite PowerShell 7 ili PowerShell 5.1 s potrebnim dopuštenjem.

Kada radite s web uslugama, potrebno je testirati određeni TCP port.

Izvršite^(Perform) dijagnostiku rute za povezivanje s udaljenim hostom.

Pronađite zadani port web-mjesta

Test-NetConnection -ComputerName microsoft.com -CommonTCPPort HTTP

Pokrenite Trace Route za web stranicu

Test-NetConnection -ComputerName google.com -TraceRoute

Međutim, korisno je ako ste na platformi koja nije Windows, ali koristite istu naredbu kao u sustavu Windows^(Windows) .

Osim toga, primijetio sam i izvršavanje naredbi za neke web stranice poput Microsoft.com . Ne radi. Ping ne uspijeva cijelo vrijeme, što bi moglo biti stvar poslužitelja koja blokira takve nasumične zahtjeve.

Troubleshoot Windows Server Network connectivity issues via PowerShell

Windows Server offers tons of tools for admins іn case an application or сomputer is not able to connect to a specific port or server IP. One thing that instantly pops up is using toоls to resolve DNS and other network issues, but if you loνe using PowerЅhell, there is a brilliаnt command Test-NetConnection that you can use.

Troubleshoot Network connectivity issues via PowerShell

You can use the Test-NetConnection cmdlet to find out diagnostic information for a connection. It includes support for the Ping test, TCP test, route tracing, and also route selection diagnostics.

Depending on which options are used, the output will consist of information such as ComputerName, RemoteAddress, SelectedSourceAddress, OutgoingInterfaceIndex, SelectedNetRoute, and more.

Here is the list of supported parameters

• CommonTCPPort: Specifies the typical service TCP port number
• ComputerName: Specifies the Domain Name System (DNS) name or IP address of the target computer.
• ConstrainInterface: Specifies the interface constraint to use for route diagnostics.
• ConstrainSourceAddress: Specifies the source address constraint to use for route diagnostics.
• DiagnoseRouting: Indicates that route diagnostics run to output the route and source address selection information for the remote host.
• Hops: Specifies the number of hops to traverse in a traceroute command.
• InformationLevel: Specifies the information level Detailed or Quiet
• Port: Specifies the TCP port number on the remote computer.
• TraceRoute: Indicates that Tracert runs to test connectivity to the remote host.

List of Sample Commands

Here are a few sample commands you can try on your computer. Some of these commands will need admin privileges, so make sure to launch PowerShell 7 or PowerShell 5.1 with the required permission.

Test-NetConnection youtube.com

More detailed information on the connectivity:

Test-NetConnection youtube.com -InformationLevel "Detailed"

When working with web services, it is to test a specific TCP port.

Test-NetConnection youtube.com -Port 443 -InformationLevel "Detailed"

Perform route diagnostics to connect to a remote host.

Test-NetConnection -ComputerName itopstalk.com -DiagnoseRouting -InformationLevel Detailed

Find the default port of a website

Test-NetConnection -ComputerName microsoft.com -CommonTCPPort HTTP

Run Trace Route for a website

Test-NetConnection -ComputerName google.com -TraceRoute

That said, it is beneficial if you are on a non-windows platform but uses the same command as in Windows.

Apart from this, I have also noticed executing commands for some websites like Microsoft.com. It doesn’t work. Ping fails all the time, which could be a server thing blocking such random requests.
