help me with static IP problem

Post by Vamsi158 » 2016/10/14 08:22:26

My host is windows 10. Guest is centos 6.4 running on vm ware.
I configured a static IP address to centos.
In vm settings , I put the Network Adaptor as –Bridged.

Using one internet modem only I am able to connect from win10 using putty.
With other devices/modems/routers neither able to connect using putty nor able to ping google.com

Kindly help me what are the changes I need to do with my centos 6.4 playing on VM ware.
I should be able to use different internet connections.

From Inside centos comand prompt:

[root@master ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0

Don't run 6.4 - it's ancient, riddled with security bugs and badly in need of updating. Current version is 6.8 and is just a yum update away.

The rest of your problem appears to be a Windows one and you need to ask on a forum that has more knowledge about that.
The future appears to be RHEL or Debian. I think I'm going Debian.
Info for USB installs on http://wiki.centos.org/HowTos/InstallFromUSBkey
CentOS 5 and 6 are deadest, do not use them.

Hi TrevorH,
Thanks for the reply.
my centos version is 6.7
[root@master ~]# lsb_release -d
Description: CentOS release 6.7 (Final)
sorry for improper information.

Inspite of the windows10 problem , I expect if I can add any changes in VMware settings or centos configuration.
because with my past experiance , windows10 can do nothing with this problem.
Kindly help me.
