I doubt very much that the Microsoft Loopback Adapter is what you need. As @Jaap suggests, try installing npcap. Also, you can read more about loopback capturing on the Wireshark Loopback capture setup wiki page.

May 08, 2016 This tutorial describes how to monitor traffic to the minimal-net platform, with Wireshark and a loopback interface, using the webserver as an example. Using this platform makes for easier debugging since you can add printfs without worrying about fitting everything into flash. I doubt very much that the Microsoft Loopback Adapter is what you need. As @Jaap suggests, try installing npcap. Also, you can read more about loopback capturing on the Wireshark Loopback. When installed on Windows Vista or later (including Win7, Win8 and Win10) with option 'Support loopback traffic ('Npcap Loopback Adapter' will be created)' selected, it will create an Npcap Loopback Adapter that can be selected in Wireshark so as to capture IPv4/IPv6 loopback traffic. When installed on Windows XP or earlier, it will install the. Assuming that your client and server are on the same machine and your OS is Windows (as you're using VB), then Wireshark, or more precisely WinPCap, can't easily capture such traffic. See the Wiki page on Loopback capturing for more info. After installation, Npcap will create an adapter named Npcap Loopback Adapter for you. If you are a Wireshark user, choose this adapter to capture, you will see all loopback traffic the same way as other non-loopback adapters. Leviton visio stencils download. Try it by typing in commands like “ping 127.0.0.1” (IPv4) or “ping::1” (IPv6).
Every time I try to filter to just show a specific IP address, I get an error indicating that it is 'not an interface or a field.' I have no idea what that means. Furthermore, I don’t really see any localhost traffic in the logs anyway.
How can I show TCP localhost traffic?

If you are trying to this on a Windows computer, unfortunately it is not possible out of the box. You will need to install some additional software that will capture data on the loopback interface.
On a Linux computer, you will need to capture from the loopback interface which is AStopher
lo most of the time. Most other Unix operating systems use lo0.

To keep this current, as hsluoyz said, install npcap

Although you found the answer before I could respond, you can also use Socket Sniffer, which looks at Winsock calls and monitors network sockets; the download link is at the bottom of the page.

Use RawCap, to capture traffic of localhost (127.0.0.1). You just need to download Rawcap.exe and run it. It will open its command prompt listing interfaces. Now select one of the interface which has loopback address 127.0.0.1.

Recently, after prompt initiated update, the Wireshark could no longer detect my ethernet interfaces, leaving only USBs on the list.
Since problems persisted after reboot I decided to reinstall Wireshark with all the same options. The situation didn't improve, at which point begun to suspect the driver.
Quick check gave me conflicting information.
So apprentlly, the service was present, but couldn't start, because relevant file was missing. With Wireshark still coming up empty, I decided to uninstall npcap also, and start with a clean slate.
Unfortunately, uninstalling Npcap turned out to be harder than I thought, failing and producing following log:
Truck serial number decoder. Reading service options from registry
Windows CurrentVersion: 10.0 (Win10)
Trying to stop the driver.
Stopping the npf driver
The Npcap Packet Driver (NPF) service is not started.
More help is available by typing NET HELPMSG 3521.

Stopping the npcap driver

More help is available by typing NET HELPMSG 3521.
Npcap service is not pending to stop.
Npcap. Device manager also detected the Npcap loopback interface.
So the driver service wasn't running but apparently some vestige of it remained. As a test, I tried to reinstall Wireshark, along with Npcap.
To my surprise, the Wireshark detected Npcap (of appropriate version) and didn't let me install it again.
And finally, I checked the:
To see if the relevant files are present, only to find both of them.
Wireshark Windows Localhost
This is all the more vexing, because I have the same version running on my laptop. I don't know where to go from here.

The issue were old Npcap drivers in Windows driver store file repository. For reasons beyond my knowledge neither the installation or removal procedure detected them.
While I'm not completely sure how, these leftovers blocked installation of full Ncap driver suite. To remove them I used following batch script (from Jonatan Van Hove):
![]()
Afterwards I simply reinstalled Wireshark, to find it's functionality restored. So far I haven't encountered any further issues.
