the host image has an apache server running, and I want to access the server from the local machine. I can access the server with the IP address, but not with the name.
I've set up bridged networking so that I can have KVM virtual machines that are accessible from outside the host. I can access both the Host and my VM from other machines on the local network, and from the VM I can access the internet but from the Host I can only access my local network. Since I can access the local network and the same issue applies regardless of whether I use host names or IP addresses I suspect it's not picking up the gateway properly.
How do I go about allowing the VM host to access the internet while still having bridged networking so I can access my VMs?
What I've checked so far: Ping Google DNS (8.8.8.8 ) From Host: Destination Host Unreachable From VM: Suceeds
[Code].....
The issues are only with accessing things outside of my subnet. I can access other machines on the same subnet from the Host just fine.
My server is installed on a guest OS on vmware. It really bugs me because I can't access it from the host OS's browser even though there is no discrepancy between /etc/hosts, /etc/sysconfig/network, httpd.conf files. Issuing ifconfig command also returns the same IP. I have also enabled netwroking in the vmware settings. And I can ping the guest OS's IP from the host.
I'm running a Fedora 10 box behind a Comcast cable modem that provides squid and mail services to 15 XP and Vista workstations. I upgraded the ethernet cards on our Fedora box to support our new 1 gigabyte network. I kept the same device configuration eth0 and eth2 by updating the /etc/udev/net persistent file and changing the ethernet hardware address in the respective ifcfg-eht files in the /etc/sysconfig/network-scripts. The box booted to the new cards, the route and ifgonfig shows the new cards and their hardware addresses, the configuration looks as how the old cards looked (eth0 and eth2 respectfully). I was able to browse the local network and have access to the internet as before from inside the network . However I cannot get access to our web server that serves our web host and our VPN services from ouside our network. I tried stopping the firewall and still could nor connect from outside the network.Could my old ethernet hardware address be hard coded somewherel?
I have Fedora 12 (Fedora-12-i686-Live.iso) installed and booting in a VMWare workstation (version 6.5.3). I am able to login as the LiveUser.
I need information on how to access the drives on my host which is WindowsXP. My C: on the host is shared, and my network adapter for the VM is "NAT".
The only directory listed in my /mnt directory is "live".
My Fedora enviornment is "bare bones". There is nothing installed except for the original files from the "iso" loading procedure.
I also have been unable to get the VMWare tools installed, and I don't know if this is related. I don't mind bypassing this if this isn't required. My only desire right now is to access my C:
I have a WindowsXP virtual machine which I need to isolate from the host machine completely (have the host act as a bridge but not be visible on the IP layer at all.) It still needs to have Internet access. Obviously it has to be able to contact the router but I would like to be able to block port 80 (or even just block all SYN packets addressed to the router.) I also want to allow port forwarding from the router to the virtual machine. I can use basic iptables but this is way beyond me.
The host OS is probably going to be Debian Lenny but this is not built yet so if someone can recommend a different distro which is as lightweight as possible but will support VMWare, iptables and tcpdump then that would be great. I was thinking of Slackware but I have not used it in ages and from what I can remember their is no real package management.
host is windows 2003 server 64-bit guest is ubuntu 9.04 server 64bit Qemu : 0.11.1 Qemu manager: 7.0
from Qemu manager, if network card is using User Networking, it's a NAT and I can see that Guest Ubuntu has an ip address 10.0.2.15 and is able to access the internet. However, as Guest ubuntu is running server so I want to do use Tap networking and I assue with Tap, the Guest ubuntu will get an ip address which is in the same subnet as host machine by dhcp. so from Qemu Manager 7.0, I changed Network card to be:
NE2000PCI Vlan Number =0 VLAN Type: Tap Networking Mac address: tap0's mac address from host TAP Network Adpator: Tap0
Note that tap0 was created by openvpn. and then fired Ubuntu guest, ifconfig shows no ip address on eth0 (which has the same mac address as Tap0) so the guest Ubuntu has no ip address and can't access public.
I couldn't find a clear answer to this, but is the linux-image-virtual package for host machines that will contain VMs, or a VM-oriented kernel for guest OS (ubuntu)? I have some guest VMs running on Microsoft's Hyper-V, and was looking for some further optimizations.
I am working on a cluster for a molecular dynamics class and I have to edit my FORTRAN code (only the newest and best for me!). In order to get through to the cluster I have to ssh in. The network on which the cluster resides is behind a firewall, so I have to ssh through the firewall into the network first.
this is fine, I can login and move files and folders as needed, including sftp-ing into host 1, then into the cluster so I can transfer files from cluster to host and then host to me. This gets rather tiresome, so it would be nice to edit the files in place.
The problem is that when I access my code with emacs it launches the emacs client on Host 1, with no mouse support. I know the purists will howl about how I should be using keyboard shortcuts, but I am a chemist and not a programmer, so the mouse is very nice for me. Is there any way I can perhaps mount the cluster using sshfs so that when I open my code it launches a local instance of emacs? Sorry if this is the wrong forum, but I thought it was network related.
I got a bunch of machines (~10) that I share with my co-workers. I have appropriate .ssh file(s) set up so I don't get prompt for password when I try to ssh.Currently I ssh into these hosts and then do a top to check the load before I start using the machine. Because I don't want to be on a busy host.Can someone show me how to write a script that find a least-busy host given a list of hosts to check? (hardcoded is fine)
The internal network is behind nat done by the PC Router.The TP Link is recieving wireless signal from outdoors and it has switching and basic routing capabilities. I'm using the PC router for better routing options.PC Router (or R for short) is a triple-booting machine - Linux, FreeBSD and Windows. It has two lan cards - external (ext_if) - 100Mbps Realtek 8139 and internal (int_if) - 1Gbps integrated Realtek 8169.The problem is that all traffic from R to the network is slow - about 5-20K, while the traffic in the oppoiste direction is all right - about 10MB that is fine for 100Mbps cables, NICs and switches. The problem persist no matter the OS the pc R is running.I've tried some debugging on the situation as follows:
- put another PC at the place of R - everything is fine. That exclude the possibility of damaged cables, RJ-45s, switches and etc. - connected both of the NICs to the Internet while the internal network is being disconnected and they both work fine (no delays) - traffic shaping is not running - there is nothing in firewalls except NATing the internal network (and it is working fine). Actually these firewall rules have been operational for more than months and everything was fine untill a week or two ago. - changed the internal NIC with another - connected the internal network directly to the TP and all of the PCs are getting good network performance. Then connected the R machine to the TP as well and there was good performance between the internal network PCs and R. - R has good performance to the TP. In fact everything has good performance directly to the TP (when not connecting trough R). - the problem persist only between R and machines from the internal network.
I'm setting up a LAMP production server for the first time. When I installed Ubuntu server edition, I selected to install Samba. My idea was to be able to easily access the server's files on the LAN using Windows. All was well and I could ping/ssh between Windows and the Ubuntu server without any problems using the host names. Later, I became concerned that running Samba on a production server might introduce security issues. Therefore, I used apt to purge Samba.
Now I am unable to ping/ssh between the Windows machines and the server using the host names. It only works if I use the IP address.
Two questions:
1.) Is it a security risk to run Samba on a production LAMP server?
2.) How do I get back to being able to use host names without installing Samba?
I am using ssh on windows XP to remotely connect to a UNIX server that provides web application development services. The server is called snapper and is also designed to run computer-intensive engineering and GIS applications. I have been able to successful access the server. However, when I try to run an application I get an error message saying:Application initialization failed: no display name and no $DISPLAY environment variable
The ANSYS Launcher could not be started The most likely reason is that your DISPLAY environment variable I either not set (i.e. issue setenv DISPLAY dev:0.0 where dev is your device name) or is set to a device that is not accepting the connection. I was hoping someone could explain to me what the DISPLAY environment variable is and how to set it.
is it possible to use yum in any way when a computer is not connected to the internet(but when full install media is available; for example the dvd)? Or should I resolve all dependencies manually using rpm?
I'm running sugarCRM with fedora 11.I want to make my sugarCRM send email to my gmail account . But I always get this error : imap.gmail.com: No such host. I'm sorry to bother this question here ,but I can't fine a good answer from SugarCRM forum .And I have struggled with this question for days .Here are some details:
Operating system type and version Fedora11 Sugar version and edition Sugar Community Edition Version 5.2.0j Webserver type and version httpd-2.2.13-1 PHP version php-5.2.9-2.fc11.i586 MySQL server version mysql-5.1.37-1.fc11.i586
I would like to access the ssh port of my office linux host from home. Unfortunately the host is located behind a NAT router. So, the IP address is not publicly available. There is however access to another internet host (Server) which is unfortunately only non-root access.
-Office PC (linux, root access) behind NAT (IP not public) but full Internet access. -Server PC (linux, no root access) static and public IP and full Internet access. -Home PC (linux, root access) behind NAT (IP not public) but full Internet access.
I want to give some web address to host file and except these web address no website will open. For example I give permission for [URL] and [URL]. The user just enter these 2 website. Other websites will be blocked.
We are using Nagios Server for different sites say India,US,Germany. All of them are in their respective groups. Now how do i create web access to 3 of them, so that they can monitor only their server? Say, India shouls be able to see and monitor only India group, US guys should able to monitor only US servers. And they not be anle to access other group.
I used to be able to access the web server I had running on my guest OS in Virtual Box from my host OS. I also had it set to the network settings of "Host Only Adapter". Then I needed to access the internet directly on the gues OS, so I changed my settings on the guest OS to "NAT" (in virtual box), and in /etc/network/interfaces, I removed the loopback stuff and the static IP I'd put in. Now no matter what I do, I cannot get it back to being accessible from the host os! I even did a completely NEW install of Ubuntu guest OS in Virtual box Guest OS: Ubuntu 10.04 Desktop Host OS: OpenSUSE 11.3 VirtualBox: 3.2.6
I've just installed LAMP. http://localhost/ page works fine. I need to create some virtual hosts. Localhost page is situated in /var/www/. It's normal for me, and I wanted to created virtualhost (in /var/www/vhost1) But it doesn't open in browser. Where is my mistake?
/etc/apache2/ports.conf Code: NameVirtualHost *:80 Listen 80 <IfModule mod_ssl.c> # If you add NameVirtualHost *:443 here, you will also have to change # the VirtualHost statement in /etc/apache2/sites-available/default-ssl
To make a very low level backup of my laptop prior to upgrading it, I decided to create an iso of the harddisk; while it is doing this, but a bit too far to just cancel and start anew, so I cannot test it out right now I decided to post here.
of course, there are partitions on /dev/sda (there's a swap for example)I may (am pretty damn sure I will) want to access the files within the iso, and that's where I wonder how to tackle that; I'm thinking along the lines of setting up a loopback device (losetup) but I don't think that that will be enough to recognize the partitions. Any thoughts? (or just re-create an image of /dev/sda1 ?)
WinXP Host Ubuntu 10.04 is the guest Mysql is installed in ubuntu and it works fine in the guest (ubuntu) Internet works fine in the host and the guest. Bridged Network.
Now, here is the thing... i want to access mysql from my host to load some data into it.
I can not access my MySQL database from any remote host on my home network, I keep getting "Access denied for user 'dbuser'@'192.168.1.10' (using password: YES)"
From what I've read this seems to be a permission problem, I tried
I've installed VirtualBox OSE and have a couple of guest OS setup. I am running Ubuntu 11.04 and VBOSE version 4.x (the most current). Now this installs the guest OS virtual harddrives to a folder in my home directory. How do I get other users on the same host machine access to those virtual machines within VB? Currently logging in as another user and going to Applications/Accessories/VirtualBox OSE ... the list of guest machines is empty save of course on my login.
If there is a general NFS share in the LAN and for example this share has three files - a, b, c is there any way to restrict file access to the root user of one particular host(falcon) in the same LAN environment while the normal users from the same host(falcon) should be able to access the NFS share & files a, b, c.
