I have Fedora 14 installed in VirtualBox, running in MS Server 2008.There is Oracle 10g software installed in Fedora 14.How can I configure connection to Fedora 14 from MS Server?Anything I've done is useless.I need to open port 1521.I can ping Fedora from MS Server. I can make connection "telnet localhost 1521" succesfuly in Fedora. But that's all.

VirtualBox-3.2.8 (the non-free version) seems to be able to tell my wlan0 connection to 'split' into 2 IP addresses: one for the OS inside VirtualBox and one for the host. My router runs Tomato and I can see both real and virtual machines with different IP addresses in the device list (I can also visit httpd running on my host machine from inside the virtual machine). Is it possible to replicate this outside of VirtualBox?
In my case, I would like to be able to 'split' wlan0 into 2 with one IP address for normal network use and the other 'assigned' to eth0. eth0 is "shared to other computers" from NetworkManager and is currently connected to a Belkin router. My goal is to have this Belkin router assigned an address that all machines in my Tomato network can access (I have an OpenBSD 4.7 home server connected to the Belkin).
Whilst VirtualBox was running I tried to see if bridge-utils was being used:
Code:
[root@1 ~]# brctl show
bridge namebridge idSTP enabledinterfaces
...but it appears as though it isn't.
I have a rather urgent problem with my network, I got two virtual network interfaces one internal and one external. The problem is; I can't get connection to internet. The external NIC is set as a NAT and the internal is... internal.
/etc/network/interfaces
auto eth1
iface eth1 inet static
address 192.168.1.200
netmask 255.255.255.0
Running with this configuration makes my internet connect go away, however if I remove the configuration for eth1 everything is working fine.
I need to set up a little virtual network with Debian Lenny guests (the host is Debian Squeeze, but I don't think it matters). I installed Lenny in a VM and it works fine. Then I cloned the hard drive, garion@Laptop:~$ VBoxManage clonevdi Linux 1.vdi Linux 2.vdi created a new VM with exactly the same settings as the first one and booted the new disc. The problem is that there's no eth0 in the new VM, but it is in the original one. Also if I "unplug" the cable, dmesg won't notice anything. In the original VM it works fine. They both have the same virtual network card: PCnet-FAST III (Am79C973). I've also tried NAT as well as internal network settings.

Winduhs is not allowed to directly access The Internets, and I am not setting up bridging as that makes it possible for the guest to mount layer 2 attacks on the LAN. I need for the guest to tunnel through the host without being able to see anything on the host, so it can then get access to The Internets, while being protected by iptables (Shorewall).
Used to be with VMware I had host-only set and the guest in a different class c (192.168.2.1) from the host (192.168.1.1) I turned on ipforwarding, set Shorewall rules, and it all worked. Now I have everything set with VirtualBox, and it does not work. Guest can ping its interface but not host. Host can ping vboxnet0. Host is supposed to masquerade guest's 192.168.2.1 through to the default out at 192.168.1.1, but it's not. I think a clue is in routing, but I don't know what's wrong.

Recently, I had the courage of installing Fedora 11 on my laptop while risking of trashing my Windows XP. Fortunately, the installation went fine and windows and fedora seems to be working together. But I needed to reinstall Fedora because I didn't do the partitioning right. After that the problem arises. I couldn't connect to the wlan. The first installation it was working fine. Now I can't. I select the network, enter the password and then it just says "Disconnected" or something like that then nothing else happens. So I had to reinstall it again thinking I did something wrong on the installation. But still it wasn't working. But it seems to be working when I boot from the live cd. I must have messed up my network configuration.

View 2 Replies View RelatedSo I'm wanting to learn a bit more about networking (ok, ALOT more), and I was thinking of trying to setup a virtual network via Virtualbox on my desktop, and as seperated from the internet as humanly possible (preferably no connection whatsoever).
Ignoring a few of the obvious problems (like my little dual core potentially running half a dozen VMs on 2G RAM), I am wanting some guidance as to what programs I would need or some documentation on setting things up.
I have no real clue where I would want to start with this, but I want it as a testbed for future toying with, to learn from, and just generally as something for me to hack at to see what does what, how, and why.
I am trying to learn about networking and am looking to set up a mini network between three bare bones Centos machines in Virtualbox. I set up the machines with a static IP. In the Virtualbox I am using NAT and have the IPs as follows
Centos-1
IP: 10.0.2.15
Gateway: 10.0.2.2
DNS: 10.0.2.3
Centos-2
IP: 10.0.2.16
Gateway: 10.0.2.2
DNS: 10.0.2.3
Centos-3
IP: 10.0.2.17
Gateway: 10.0.2.2
DNS: 10.0.2.3
On all machines i can ping google.com, and yum updates, but I can not ping any other machine. It says they are unreachable. NOt really sure what to do. Any help would be much appreciated.
I'm having a bizarre problem where my network connection stops working randomly. At first I thought it was a DNS issue since Firefox simply chilled out on "Looking up [hostname]" until it timed out, but after further investigation (pinging IP's, "host" and "dig" being unable to reach servers) it became apparent that I couldn't even access the DNS servers i.e. the Wicked Connection of the East was most sincerely dead.
There are two strange things about this: one, there are no errors except "timeout". The network manager is happy, Firefox is happy until the lookup fails... Two, the failures only start *after* DHCP configuration. DHCP configuration never has any trouble sending or receiving packets. I'm going to try static IP and whatnot to see if that helps, more information later.
I currently have VirtualBox installed on my Ubuntu 9.10 Desktop. I have windows xp as a guest os and it has network shares on it. My question is, is there a way for another computer to access those network drives on the guest os in virtualbox? I don't want to search for hours on end on google, a simple no would be fine - however if it is possible let me know because when I am in windows on another computer that has windows as a host os it sees it in the windows network folder but it says "....network location not found" or something similar but it still shows a pc picture of the virtual os of the virtual box program running in ubuntu.

View 13 Replies View RelatedI am using Fedora 14 x86_64 as the host and Windows XP under VirtualBox 4.0.4. I have added two ports (TCP and UDP) to the firewall settings in 'other ports' in the Fedora firewall setings. Do i need to do this?I noticed the port forwarding option in the Fedora's firewall settings which asks for either the ports to be forwarded to either local or an ip address. Do i need to do anything here?
In the settings under VirtualBox under Network adapter 1 (which is enabled) and attached to NAT, there is a port forwarding option in the advanced settings. Can the host and the guest port be the same number? If i use 'open port checker' to check if the tcp port is open in windows xp, will it work as it does in firefox under Fedora?
My USB-modem and my freerunner phone is no longer recognized by fedora. Last time this happened I just reinstalld Fedora because I had no id�a what caused the problem. But now I recognized that virtualbox was the last package I installed before the problem occured.

I have my new router all set up, and everything is working fine, but I'm having problems adding a password to the network.The network from the wireless router is called "auto dlink" by default, and I've tried through the Gnome interface to add a WEP 40/128-bit key that I generated through a website. As soon as I apply the change to the network, the connection drops, so I click on the "auto dlink" network again to connect, and it successfully does, but it never asks me for the key that I configured it to ask for. After checking the network connections history, it shows me as having connected to two different "auto dlink" networks at different times - the one that I added the key to, which is no longer available, and a new one that I am currently connected to, that does not have a key. Every time I try to make a change to "auto dlink," be it a change to the security or to the network name, the change registers and applies, but the network ceases to be available and is instead replaced by a new, default configuration of "auto dlink."

I'm a Linux n00b (very fluent in Windows, though ) that is attempting to set up a (currently) 3-computer cluster. My server node is a Pentium 4, and my client nodes are a Pentium 4 and a Pentium 3 (whatever I have lying around ) I chose to use OSCAR for my clustering interface and CentOS 5 for my server node OS. Yay. I made it through the installation prerequisites, but when it came to configure the NIC, I got stuck.
I opened the /etc/hosts file, tinkered with it, but something inevitably got screwed up. I can still use the Internet, but it won't let me install OSCAR. Running a system-sanity check returns:
Code:
[root@SurgeonfishR ~]# system-sanity
Checking your system...
Success: ssh-check.pl
Success: tftpboot-check.pl
Success: selinux-check.pl

All I need to know is what the /etc/hosts file should look like for a CentOS 5.4 installation with 1 NIC that is not connected to a domain (only a LAN). It is connected to a router which in turn is connected to my home network (I don't know what to do about that). The hostname should be surgeonfishr and the IP address should be 192.168.0.150.
I know this question is probably really stupid, but I've logged a total of about 10 hours time on Linux...ever. (And 35000 hours on Windows.)
I am having trouble for routing port 80 from a Billion adsl modem to a guest server in VirtualBox. There are quite few different changes from my last setup so I kind of confuse which one is wrong.
I used to use have the setup belowusing modem Linksys WAG354G use static ip 192.168.1.100 for my machine use static ip 192.168.1.102 for my guest VirtualBox server guest OS is serving http listening on port 80 i use bridge from my host OS for VirtualBox set my modem to direct all traffic on port 80 to 192.168.1.102 host OS was Fedora 11
now I useusing modem Billion 7404VNPX use same static address and configuration host OS is Fedora 13
main issue is I cannot reach the guest OS if I navigate to my modem ip address. (e.g. http://192.168.1.1) if I change the modem to direct all traffic to my host OS ip address (192.168.1.100) it works nicely.
I have tried to disable and enable the firewall without any luck.
I created a F14 x86_64 guest OS in VirtualBox4 (hosted by F14 x86_64) and configured it to get its IP from my router but it won't do so on boot. The other guest OS's (Fedora 14 i386, 2x Oracle EL5) are able to get their IPs on boot.
I checked the setting in the network manager and they show that the interface is to be activated on boot but it doesn't. When I log in and run ifup eth0 as root it works.
i'm currently using ubuntu 10.04 and wanted to update to 11.04 and that means backing up all sorts of data and configuration.Regarding the wireless configuration list, i have a few with password and auto connect, i wanted to know if there is a way of saving that listconfiguration other then manually.

The other day I was using BitTornado and it was running so slow it was almost unholy. After some research I found out that if the yellow light was on it means I couldn't receive any incoming connections and had to open some ports on the firewall. That, my friends, is not the problem. I tried to manually open up the bittorrent port and did some other things that I can't quite remember but eventually I accidentally killed all bittorrent functionality on my laptop.
Is there any way I can reset my network and ports back to the default settings or am I utterly screwed? I'd really prefer not to have to reinstall my whole OS just to fix my bittorrent or worse, have to download on Vista *shudders*. I'd rather go back to my uber-slow bittorrent than none at all. I've tried everything I can think of, even the godlike might of Google couldn't get me out of this one. Now I am forced to bother you, all because I wanted to see a damn sci-fi film from Switzerland (Cargo[2009]).
