Windows: Set network parameters from command line by using WMIC.exe


you can use wmic.exe  to set some network parameters (and much more, its WMI!!) from command line. Syntax is very hard, but it works :-).

For Example. If you want to disable the DNS registration of all enabled Intel e1000 network adapters.

wmic path Win32_NetworkAdapterConfiguration where (IPEnabled="true" and ServiceName="E1G60") call SetDynamicDNSRegistration False,False

The Filter in the braces is the where condition of wmi “select * from NetworkAdapterConfiguration where IPEnabled=’true’ and ServiceName=’E1G60′ ” statement.  Modify this for your needs. By using WMI queries this is much more flexible than netsh command lines.


OpenVPN: Set a static IP Address for a client


sometimes you have to set a static IP Address for some VPN Clients. Because they provide some server services which always must be reached at the same IP Address.

The client configuration do not provide any option to do that, set a static IP Address on the adapter itself is also always being overwritten when the client establish a connection to the OpenVPN server.

Solution: Define a client specific script at the server.

In this example the openvpn server’s OS is linux (tap Interface IP, the client runs at Windows (static IP

Define a directory where the client scripts should be stored , e.g. /etc/openvpn/staticclients and create the directory

mkdir /etc/openvpn/staticclients

Add this directory as option to your openvpn configfile at the server:

client-config-dir /etc/openvpn/staticclients

For each client you have to create a file. The filename must match the “common name” attribute that was specified at the X509 certificate of the client.This command gets the CN from the computers certificate:

root@devdeb~ > openssl x509 -in /etc/openvpn/yourClientCertificate.cer -noout -subject | sed -e 's/.*CN=\(.*\)\/.*/\1/'


This example pushs the IP Address to the Client with the common name TESTCLIENT and also pushes a additional route for subnet

cat /etc/openvpn/staticclients/TESTCLIENT

push "route"
# push "dhcp-option WINS addr"
# push "dhcp-option DNS addr"
