    connectivity between OVM linux and windows

    Sami A.
      hi !

      I want to access the EBS running on the OVM from my windows but iam unable to .
      I can ping to the OVM linux box but i cant reach it on port 8000.

      here are the settings from the linux box

      eth0 Link encap:Ethernet HWaddr 08:00:27:DB:0F:7B
      inet addr:10.100.12.171 Bcast:10.100.13.255 Mask:255.255.254.0
      inet6 addr: fe80::a00:27ff:fedb:f7b/64 Scope:Link
      UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

          and my network file looks like this

          NETWORKING=yes
          HOSTNAME=OEL6EBS12.localdomain
          GATEWAY=10.100.12.1

          and the port 8000 is opened in linux firewall .

          [root@OEL6EBS12 ~]# netstat -tulpn | grep 8000tcp 0 0 0.0.0.0:8000 0.0.0.0:* LISTEN 2692/httpd
          [root@OEL6EBS12 ~]#

            and the iptables on linux is as follows :

            [root@OEL6EBS12 ~]# cat /etc/sysconfig/iptables
            # Generated by iptables-save v1.4.7 on Tue Apr 9 14:23:08 2013
            *filter

              What is OVM linux box? Are you using Oracle VM server for x86 or Oracle VM VirtualBox.

              If you want to test whether or not the Firewall is the problem, simply disable it for the duration of your test:

              service iptables stop

              If you using Oracle VM VirtualBox, your ability to reach the virtual machine from your host depends on how you have setup the virtual machine network adapter, which restricts access based on NAT, host-only or internal network configurations. Check VirtualBox manual.

                iam using OVM linux 6.4. and I can telnet to port 22 from my windows box to ovm , so why not to port 8000?
