I'm trying to change my ip address to a static ip addres with the following netsh command:
netsh interface ip set address name="Wi-Fi" static x.x.x.x 255.255.255.0 x.x.x.x 1
But this only changes my default gateway and doesn't affect anything else. Sometimes it doesn't even affect the gateway. The result looks like this:
What am i doing wrong?
You can try and explicitly state all the values:
netsh interface ip set address name="Wi-Fi" source=static addr=x.x.x.x mask=255.255.255.0 gateway=x.x.x.x 1

Good afternoon to all! I ran into a problem when setting up my network. The essence of the problem is that I can't ping the address google.com , but I can ping Google DNS 8.8.8.8 I can't do it on a Cisco IOSv router that is connected to the internet using NAT and also on other devices behind it I can't do it. But to check, I connected a PC and was able to ping google.com . Of course, I tried to set up NAT on the router, prescribed NAT INSIDE and NAT OUTSIDE, but it didn't help. I will also attach all the screenshots to make it clear. Most likely I just missed something.
My network:

I was given an answer from GNS3 Forum (from Ean Towne
GNS3 Moderator). Here 's what he wrote:
"You have disabled the ability for the router (R1) to DNS lookups, and also have not specified the IP address(es) of the DNS to use"
R1(config)# ip name-server 8.8.8.8 1.1.1.1
R1(config)# ip domain lookup
"People often add the "no ip domain lookup" by default in order to remove failed lookups when making typos. However they do not necessarily think about the effect of the same"

I am looking for a way to change the IPV4 IP address settings to a specific IP and Subnet mask, but also to change it to get the IP address automatically. I see plenty of resources for setting the IPV4 IP and DNS settings in windows cmd, but I don't see where i can change it to the "Obtain IP address automatically" setting.
Basically, I need to quickly switch my settings from the default IP wifi settings to a specific IP address and subnet mask (well, the default one, but it needs to be set when changing IPV4 settings), and back when I need it.
DHCP is used to obtain IP address automatically. When you'd want to revert the interface to using DHCP again, just run the following commands.
netsh interface ip set address name="<adapter-name>" dhcp
netsh interface ip set dns name="<adapter-name>" dhcp
ipconfig /release <adapter-name> && ipconfig /renew <adapter-name>
I am using VMWare 10, in that installed CentOS 6.5 with two networking interfaces (eth0,eth1).
When I try to use the vmware, every time the ipaddress changes.
How to make the IP address constant (not a static IP address)?
Vmware will by default allocate dhcp ip addesses. In order to have static IP address, please assign static IP address in Centos using below steps
Static IP assignment for eth0
cat /etc/sysconfig/network-scripts/ifcfg-eth0
Sample output:
DEVICE="eth0"
BOOTPROTO="dhcp"
HWADDR="xx:xx:xx:xx:xx:xx"
NM_CONTROLLED="yes"
ONBOOT="no"
TYPE="Ethernet"
Configure eth0:
In above you can look that IP address is assigned dynamically using dhcp. Change this to below, make sure you aren't changing hwaddr, device - leave it unchanged.
vi /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE="eth0"
BOOTPROTO="static"
HWADDR="xx:xx:xx:xx:xx:xx"
NM_CONTROLLED="yes"
ONBOOT="yes"
TYPE="Ethernet"
IPADDR=192.168.1.2
NETMASK=255.255.255.0
service network restart
It will work now.
I installed Bitnami owncloud virtual appliance stack on Virtual box and within no time, I was able to sync files to and from this box. However, the main problem with Virtual Box is that the IP address keeps changing when the owncloud instance is powered off and then turned back on - which makes sense. Is there any way to keep the server IP static so that we don't need to configure the clients everytime the IP is changed.
You could change the config (from auto to static) in the following way
sudo vi /etc/network/interfaces (“vi” or “nano”)
iface eth0 inet static
address 192.168.0.100
# your own IP
netmask 255.255.255.0
# network mask
gateway 192.168.0.1
# standard gateway (router)
dns-nameservers 192.168.0.1 8.8.8.8
# DNS (optional)
/etc/init.d/networking restart (restart network)
ifconfig
for the IP addresses check or you “shutdown –h now” (reboot)). Please, keep in mind that multiple copies need multiple IP's. In Virtual Box remember to switch between NAT and Bridge - if required.
Is there any way to specify a particular outbound IP address for stunnel? Right now, it's always using the main IP of the server, but I'd like it to use a specific outbound IP address.
I actually found my own answer on this one - the "local" directive.
local = host
IP of the outgoing interface is used as source for remote connections.
Use this option to bind a static local IP address, instead.
