No-ip + Port Forward To Virtual Machine - Is It Safe?
Jul 18, 2008
I've set up a website using a no ip-account, nothing fancy or business-oriented, and I have it working this way:
no-ip(port 80 redirect to port 6500)->router(redirect port 6500 to pc2 with ip 192.168.1.3)->pc2(vmware server redirects port 6500 to virtual machine with ip 192.168.60.100, which is running an asp .net server serving on port 6500)
The router does not forward any port other than that one, but I would like to know if this has any risk for the other machines on the lan.

I am currently researching the options open to me for Virtualisation, the two main ones I have seen are Xen or KVM.
I mainly use CentOS (RHEL), but have read that the version of Xen with it is very old, broken and unstable. KVM isn't included in the kernel that ships with CentOS, as it is too old, apparently it was first featured in Kernel v2.6.20. There isn't likely to be an update till RHEL6, which is due for release first quarter of 2010. I can't wait over a year, so need to find another Distro for use as the Host OS/Hypervisor.
I have built a pretty powerful server, it has an Intel Xeon 3230 which has VT - so I might be better off using KVM over Xen. I am going to collocate this server, so realistically I can make this decision only once - as it would be a PITA to re-install a host Linux distro remotely.
I did a search on distrowatch for distros with the latest version of the kernel, and Slackware came up as being just one minor version behind the most current (v2.6.27.7).
Now this distro is very mature, so should be a fairly safe bet, but it is a 32bit version and can't host 64bit VMs. I have 8GB of ram so want to be able to use it all, and offer the choice of 32/64bit VMs. So that's that out of the window.
I have used Arch Linux on and off for a couple of years as a workstation OS, but because it is so bleeding edge, when pacman updates it can break itself. But I suppose if I just use it as the Host OS, and never let it update/reboot, then it won't break. It should be fairly lightweight and stable, as I will be installing the bare minimum packages. I have a management card, so if the server fails to boot, then I can still remote in to fix it.
If I do want to update the kernel, is it possible to update without rebooting? I think it is somehow... unless I can just reboot during an unused time at 3am or something.
As you can tell I am leaning towards KVM on Arch Linux (x86_64). Is this a good plan?

I want to be able to clone a existing virtual machine image(whether it's openvz or xen) and deploy it.
It's sort of like Amazon EC2.
I want to set up a virtual machine image once. Then deploy it(it doesn't matter whether it's on the same physical machine or not) to a new machine or overriding existing image on a existing machine. It's fine that the VPS provider charge me a monthly charge for every virtual machine I deploy.
This way, I only need to maintain one master virtual machine.
It'd be even better if I can export a image to my own machine, modify it locally, then upload it for deployment.

If i try telenet 25 from outside I can not connect ! But if och do it from the server i can connect !!
It is probably something i missed, but I can not find the correct settings !
Firewall is open for 25 and 587 !

I've started looking into KVM to possibly to run alongside or even to end up replacing our current Xen infrastructure. The fact that it's built into the mainstream linux kernel is very appealing.
Are there any Control panels/basic frontends for this at the moment to allow users to Reboot/Reimage their VM's? At the moment its looking as though we would need something inhouse or custom developed

I have an Apache server running on a virtual machine and I want to be able to access the pages it serves from a browser running on the host OS.
I am using OracleVM virtualbox as my VM platform.
I am using windows 7 as my host OS.
I am using ubuntu as my guest OS.
I have managed to set up a virtual host so that it works from browsers running in the guest OS (ubuntu)
But I cannot get it to serve these pages to a browser running in the host OS windows.
The config file in the apache2/sites-available and apache2/sites-enabled has the following config for the virtual host I am trying to access.
<VirtualHost *:80>
ServerAdmin webmaster@localhost
ServerName testsite
DocumentRoot /var/newserver
<Directory />
Options FollowSymLinks

OS: RHEL 6.4
SELinux: permissive mode
Apache: 2.2, mod_fcgid, mod_suxec, mod_ssl enabled
Common Name: www.user.dept.university.edu
(Note:user names, accounts, organizations etc. sanitized)
why Apache will serve PHP-based web pages over port 80 but not over 443. Here is the virtual host block excerpt from httpd.conf:
Code:
<VirtualHost *:80>
ServerName user.dept.univsersity.edu
ServerAlias user
DocumentRoot /home/user/public_html/subdirectory
<IfModule mod_fcgid.c>

I am trying to setup a subdomain and/or virtual host to redirect to a specific port and path. I have setup my server with DDYNS through my domain name registar. Through the ddyns client I have set it to assign a subdomain of "outside.name.com" so that my server will have a easy name to get to instead of a dynamic ip address.
I have also setup on my registrars host records another subdomain of "inside.name.com" with a static IP address for internet network accessing to my server.My problem is that I have a service/program on my server that I need access to both internally and externally and this service can only be access through a port of 32400 and HTTP address of /web. (e.g. outside.name.com:32400/web or inside.name.com:32400/web)...
Is there a way that I can create a VirtualHost or Subdomain of "service.*.name.com" that redirects them to ":32400/web" of the hostname they're on? (e.g. service.outside.name.com automatically forwards or proxies--to keep it pretty--to service.outside.name.com:32400/web)

I have an office internal website and I opened a port in the gateway of my office (7080) to this website (server )'s 80 port. That makes this website open to public as office has static IP. And then when I view the site from home . it's fine. But when I tried to login, the site is using a pop-up, I guess it's http authentciation, login, I was redirected to a url without my port number any more, that stops my access to the site as obviously I would.
How can I keep my connection/port number ...?

i need to enable php safe mode on for my joomla and i came across this
Quote:
When the php safe mode is turned off globally by default at our server end, you can still override the setting to turn it ON for only your domain by just insert the following line inside the ".htaccess" file (at Linux server):
Code:
php_value safe_mode "1"
my joomla .htaccess file:
