After a lot of RTFM'ing and reading forums, I am still having problems and need some advice. I use Virtualbox on Ubuntu and installed a Centos server as a guest. My problem is that I cannot access the web server on the guest OS from the host OS.
Here are the details: Host OS is Ubuntu 12.04 LTS (kernel 3.2.0-24-generic) 64bit.
I use Virtualbox 4.1.12.
I get my IP address from my wireless router:
eth0 Link encap:Ethernet HWaddr 18:03:73:42:3d:ac UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Interrupt:47 Base address:0xe000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:3784 errors:0 dropped:0 overruns:0 frame:0 TX packets:3784 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:378673 (378.6 KB) TX bytes:378673 (378.6 KB) wlan0 Link encap:Ethernet HWaddr 64:27:37:69:c5:d2 inet addr:192.168.1.15 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::6627:37ff:fe69:c5d2/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:124013 errors:0 dropped:0 overruns:0 frame:0 TX packets:82469 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:164307087 (164.3 MB) TX bytes:9744555 (9.7 MB)
So, I installed CentOS as a guest OS and I want to access its http server. In the Network Settings in Virtualbox I have this: Attached to Bridged Adapter
I allow Promiscuous mode for the VMs.
And 'Cable Connected' ticked.
On the CentOS machine, the eth0 interface picked up 192.168.1.20 IP address with 255.255.255.0 mask. Everything looks OK so far, the two systems can ping each other. I started the web server and it is listening on port 80 - checked with netstat. (However haven't change the default configuration file of the webserver.)
When I wanna connect to the web server on the CentOS machine, I cannot. 'Unable to connect' Firefox says, Chrome is also unhappy: Chrome could not connect to 192.168.1.20. (I am not using any proxy here.)
I tried to telnet to port 80 on the guest system - no joy:
:~$ telnet 192.168.1.20 80 Trying 192.168.1.20... telnet: Unable to connect to remote host: No route to host
Not sure if it's important, but the route table on the guest OS is here:
[root@centos ~]# route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.1.0 * 255.255.255.0 U 0 0 0 eth0 link-local * 255.255.0.0 U 1002 0 0 eth0 default 192.168.1.1 0.0.0.0 UG 0 0 0 eth0
(It's funny, just figured it out that I can ssh from Ubuntu to CentOS.)
I tried different settings in Virtualbox, but the above is the closest to what people suggest on different forums. Tried NAT with port forwarding, Host-only adapter but I failed to fix it.
Can someone shed some lights for me, please? Cheers
