What are the most useful netsh commands?
By John P. Levesque A couple of weeks ago, I received an interesting email from a friend of mine about netsh . It seems like a pretty standard tool, so I went to the command line and started playing around with it. To my surprise, netsh seemed pretty powerful, and I quickly ran into some interesting use cases for it. For example, I was surprised that it let me change the proxy settings for all clients. This surprised me enough that I decided to write this article.
The purpose of this article is to explore some of the interesting things you can do with netsh, but also to show how you can use netcat to quickly and easily explore such systems remotely. So let's get started! What is netsh ? In order to explore netsh, we'll need to know a bit more about what netsh is. Netsh is a command line tool which lets you manipulate networking interfaces, and their configurations. The simplest example of this is if you run the following:
Netsh interface set interface "Local Area Connection" source=dhcp. You will be able to modify network configuration options on a Local Area Connection (LAC) object. Another example of what you can do with netsh would be to check on the configuration of various network adapters: PS C:UsersAdministrator> netsh int ipv4 show interfaces. Interface Information. Index Interface Name Media State Status Speed Protocol Address Mask MTU Refused. Ethernet (2) Connected Disabled 1000Mbps 802.3 Ethernet Disabled Ethernet (3) Connected Disabled 1000Mbps 802.3 Ethernet Disabled Tunnel0 Disabled Disabled 100Mbps Point-to-Point Tunnel Encapsulation. Ethernet (2) Connected Enabled 1000Mbps 802.3 Ethernet Disabled Ethernet (3) Connected Disabled 1000Mbps 802.3 Ethernet Disabled WiFi0 Disconnected Disabled Wireless Zero Configuration. Ethernet (2) Connected Disabled 1000Mbps 802.3 Ethernet Disabled Ethernet (3) Connected Disabled 1000Mbps 802.3 Ethernet Disabled Ethernet (2) Connected Disabled 1000Mbps 802.3 Ethernet Disabled Ethernet (3) Connected Disabled 1000Mbps 802.
How to use netsh to capture network traffic?
I'm a networking noob, so don't feel like you have to explain everything. I have this server, which I will connect to internet (my home ISP) from my laptop using a dynamic IP address assigned to it by a DHCP. I need to monitor the traffic coming and going of a couple of programs on that server, which are running.
I have read a ton about TCP dump (with Wireshark), and found out it works very well for capturing tcp traffic on a static IP address, and I already know how to do that. What I want is to get the same result, but for the captured traffic.
I searched a lot online, but I can't find anything that explains how to use netsh commands for this purpose. Most of the sites on Google only explain how to capture traffic between 2 computers or to a DNS server, nothing of the kind.
Can anyone help me with that? For Windows Server 2003: Use the command line program tcpdump and specify the switch in which you want to capture the data. By default, it's all available. For example, to capture all packets on interface eth0:
C:>tcpdump -v -i "eth0". For Windows XP: Use Wireshark and a tap device. You can do it directly through the Wireshark GUI or via the command-line interface (CLI). If you do it from the CLI, you can specify the interface on which you want to listen:
C:> wireshark -i "tap0". You can get more information about configuring Wireshark with the documentation. Note: this will only capture ethernet and wireless traffic. IP traffic is not supported. If you want to have more support for IP traffic, you'll need to buy something else.
What are the netsh commands for interface IP?
Thanks. UPDATE: I figured out that I have to set the IPV6 parameters as well. I run the following command which is close to what Netsh suggested in the answer. Netsh interface ipv4 address "InterfaceName" 10.8.1 255.0
But what about IPv6? How can I configure this interface?1/16. Note that there are two different IPv6 addresses available - one for the prefix and one for the suffix. Also note that you have to replace 10.1 with the actual IPv6 address you want to use.
