Cannot Connect CentOS VM to Internet (NAT Connection)
centos, centos6, vmware-workstation
Solution
The best option is to let it grab an ip automatically from DHCP:
dhclient -v
This will let centos get an ip automatically.
Problem
So after fighting the VMWare network giant for the past day, I decided to give in and ask for help. I have a CentOS 6 image running on Windows 7 using a NAT on VMWare Workstation 8.0.2 build-591240, and for some reason, I can no longer connect to the internet with a static IP address. This seems to only to apply to static, and not DHCP, which tells me it's either: some program on my Windows 7 OS that's blocking the connection for that IP address, or there's something weird that happened to my configuration on the CentOS image. I didn't know if this was due to a yum update, so I tried reinstalling VMWare tools. This didn't seem to fix the issue. I've also tried the following: - Made sure the VMnet connection was connected (stupid, but had to check... also I can connect to the internet with DHCP) - Made sure my firewall on Windows allowed for VMware to connect to the internet - I've seen/read that Windows sometimes blocks ping requests, so I tried going to www.google.com in Firefox, this got a "Server not found response"... so do I have to do something different for DNS?? - I checked the registry of my Windows machine, I only have 1 entry for a default gateway Like I said, this seemed to happen out of the blue. The image could connect to the internet before with no issue. Is anyone aware of a CentOS update that might cause this? I've added my configuration below to save some debugging cycles: ``` [root@MyCentOS ~]# ifconfig eth0 Link encap:Ethernet HWaddr 00:0C:29:A0:51:BD inet addr:192.168.88.128 Bcast:192.168.88.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:683 errors:0 dropped:0 overruns:0 frame:0 TX packets:67 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:64242 (62.7 KiB) TX bytes:8055 (7.8 KiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:1049 errors:0 dropped:0 overruns:0 frame:0 TX packets:1049 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:68417 (66.8 KiB) TX bytes:68417 (66.8 KiB) [root@MyCentOS ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE="eth0" BOOTPROTO="static" IPV6INIT="no" NM_CONTROLLED="no" ONBOOT="yes" IPADDR=192.168.88.128 NETMASK=255.255.255.0 GATEWAY=192.168.88.2 TYPE="Ethernet" [root@MyCentOS ~]# cat /etc/sysconfig/network NETWORKING=yes HOSTNAME=MyCentOS GATEWAY=192.168.88.2 [root@MyCentOS ~]# service iptables status iptables: Firewall is not running.
