Hi,
I have installed jenkins on a VM with centos. VM is hosted on windows 7 desktop. I have used dynamic configuration for eth0 and eth1 and able to access internet.

How do I access jenkins from windows 7 machine.
When i used eth0 or eth1 ip x.x.x.x:8080 am getting connection timed out error. What is the ip of my virtual machine to access Jenkins

How is the CentOS VM network adapter configured? As NAT or bridged adapter? With NAT mode you need to forward the port similar to a home based router using the host vboxmanage command line utility. If set to bridged mode your VM will acquire a DHCP address from your real network server. In either case make sure the CentOS firewall allows traffic on the desired port. I assume that Jenkins is installed, running and can be accessed on the CentOS VM itself.

To see your IP addresses look at the output of the command:
ip addr show

Yes. Thanks . I did the following and was able to access.
/etc/init.d/iptables stop
