Ubuntu Servers :: Configuring 10.10 Server In VMware ?

Feb 17, 2011

I have attempted to set up ubuntu server 10.10 on my home network. I only have one computer and access to windows is a must for me, so what I have been doing is installing the server via VMware as a virtual server. Now, I have been able to successfully set up a server that works on the LAN, but for some reason I have been unable to get access to the server via the external ip address.

I will list all known information about my network, host computer and VMware.

I'm currently using VMware Workstation. For the virtual machine I have installed, I have allocated 500 GB of space to a partition on my 2 TB external hard drive. The network is currently set to NAT, but I would much prefer to Bridge the network so that the guest would be assigned a unique LAN address.

The host computer is a laptop. It is connected to the internet through a wireless router. I can successfully host a teamspeak server that accepts incoming traffic from the internet. The operating system that is installed is Windows Vista.

The network is set up as follows:

The host's LAN address is 192.168.1.50 and is connect to the Router which has an address of 192.168.1.1. I am using a Netgear WNDR3300v1 wireless router. The webserver itself would likely have the IP 192.168.1.2 in the circumstance that the network was bridged for the virtual machine. So the WAN Interface would be the modem my company has provided which has assiged the external IP 24.113.92.228. The modem is a cable modem, the brand is a motorola surfboard.

Ubuntu Servers :: Multiple Websites On Single Host Machine Without Virtualisation

Jun 1, 2010

I have this intra net server project going on and now I moved to 10.04 however there are still some things that I would like to see clarification and instructions on. I am interested to set up multiple parallel websites for my apache server, however I am not sure how to do this exactly. Now I have solid address rivera.wippies.net and port 80 redirecting to my server. What I would like to get done is that I get multiple independent of each other websites for my server I was thinking of making websites like this

/var/www/site1 (which would be as rivera.wippies.net)
/var/www/site2 (which would be as rivera.wippies.net/othersite)
/var/www/site3 (which would be rivera.wippies.net/secondothersite)

etc, so that I have multiple "individual" websties for my server. Requirements would be that each of these websites could have SSL encryption as needed available too, since some of the website could have confidential information.

Ubuntu Servers :: Cannot Send Mail Outside Of Machine?

Jan 5, 2011

I am attempting to get mail working on a server, and having some trouble. I'm working with sendmail, and I am to the point where I can send and receive mail on the server (from one user account to another), but I cannot send mail from the machine to somewhere else (specifically a Google Apps GMail account). When I try to send mail to the gmail account, I receive a "Undelivered Mail Returned to Sender" message. I've never managed any sort of mail server, and so far searching the internet hasn't helped me.

Software :: Importing A Vmware Virtual Machine File Vi Vmware Server 2.0.2?

Jul 27, 2011

I completed the installation of VMWare Server 2.0.2 onto a CentOS 5.4 64-bit distribution. There is a VMware virtual machine file on the server in question, and I want to activate it through the application console.

I did not see anything readily apparent that would facilitate the importing of the virtual machine file. Does anyone have a procedure that can accomplish this task?

CentOS 5 Server :: Building VMWare Virtual Machines From CentOS Mail Servers?

Oct 12, 2010

I have a few mail servers, a mail log server and a web server running on Centos 5. Now I have a task: to avoid accidental crashes on the production servers while installing updates, my boss asked me to do clones (these clones will all be VMware virtual machines) of the servers (EXCLUDING the actual e-mails and log contents) and then to run those clones on VMWare Server. This way, first I will install and test updates on the clones and - if they will be running without crashes - I will apply the updates on the real production servers themselves.

I have already installed VMWare Server 2.0 I have a few questions: How do I build the virtual machines to exclude the actual mail files and mail logs? Can I use VMware Converter for this purpose, or do I have to use another program? How do I actually do this cloning? Is there a tutorial on how to do this?

General :: Configuring Machine As A Firewall?

Feb 8, 2010

i have a linux server runnig oracle applications. i need to access this server from putty using ssh through internet. i did by registering my static ip with the dnydns.org and i am able to connect to the server. but now there is no security to authenticate any user as any one knowing the password can login to it. i thought of configuring the firewall of linux server but the client ip`s are not static and they change continiously. so thought of keeping one more pc between the server and the router which will do the work of authenticating. but i am confuse as how to configure it to allow the packets coming from the internet after authenticating and to by pass the packets generated from internal LAN?

i have heared abut freeradius package but i am not sure will it work in my case?

Ubuntu Servers :: How To Torque On Ubuntu 10.04 On A Single Multicore Machine

Jun 17, 2010

I updated this on jul 21 using comments below Torque is a batch job queuing system that is used on clusters. But I find it handy to use it on my multi-core workstation as well. It allows jobs that need to be run to be schedule by multiple users. The scheduler will make sure that not too many jobs are run simultaneously which could cause high system loads or memory issues. I previously posted how to install torque on ubuntu hardy from the torque source package. However, torque is now in the repositories of lucid and here are the steps that I had to take to get it to work on my workstation.

For this setup I kept the server host name 'torqueserver' which is the default in the package. You can do the same or use a fully qualified domain name. In that case, you will have to adept the steps somewhat. My workstation has 8 cores, and I only want to give 6 of them to the que. Please adapt your numbers accordingly.

0) open root terminal

Code:

sudo -s

1) add torqueserver as an alias to /etc/hosts.

Code:

gedit /etc/hosts
change 127.0.1.1myHostName to 127.0.1.1myHostName torqueserver*) see post by drlemon.

Alternatively use a resolvable host name (check with 'host $HOSTNAME') in the file:

/var/lib/torque/server_name and whereever torqueserver is used below, use that host name

2) install torque from repositories

Code:

apt-get install torque*

[code]....

This works for me but probably requires more configuration in a demanding computing environment. Check out the torque website for more queue configurations, user management etc.

Apr 4, 2011

I have a network of 100 machines, all with ubuntu Linux. Is there a limit to the number of machines that can connect to one single machine (at the same time)? For example, can I have 99 of my machines maintain continuous ssh connection to the 100th machine? Can I have every one of my machines (every one of the 100) maintain a continuous ssh connection to all other 99 machines? How much memory does each such a connection take?

General :: Attempting To Get BackTrack 5 Running With A VMware Virtual Machine On Windows 7

Aug 23, 2011

I'm running a 64bit Version of Windows 7. I'm also dual-booting 64bit Ubuntu 10.04 (if it matters). However, for this I'm trying to get this working on the Windows 7 side of things. I downloaded the BackTrack 5 32bit GNOME .iso file (BT5-GNOME-32.iso) to my USB stick fine and made a VM on VMware Player. I set the OS as "Other Linux 2.6.x kernel" (if it matters). However, when I go to play my VM I get the following screen. I know I'm supposed to type Startx to launch the GUI. However, nothing happens; it's completely unresponsive (and yes keyboard focus is routed to the VM). There is no response, the cursor doesn't even blink.

General :: Automatically Run A Virtual Machine (made By Vmware In Fedora OS) At Startup In Fullscreen?

Sep 11, 2010

I am an administrator of a student lab with 20 PCs. I was thinking of a way to protect those machines in the long run with the presence of some students with destructive behaviour. The most suitable solution to install a Linux OS and use virtual machines to load Microsoft OS. This way once the OS fails I can simply replace the VM with a clone that was previously made.

The point is that most students have no experience with Linux, that's why I need to load the Virtual machine automatically at login and in full-screen view so that The startup process ends up in Microsoft OS through the virtual machine (VMWare based) in Linux platform.

update : I'm using Fedora13 Linux distribution. I believe that part of launching the VM in full-screen is more difficult than automatically launching VMWare at startup. Is there some way I can tell VMWare to launch a particular virtual machine in full-screen when it starts on boot?

General :: Auto-mount Virtual Machine Locations When VMware Image Finishes Loading?

Jun 20, 2011

I mount a few locations from a VMware virtual machine, but currently every time I start up VMware I need to re-mount the locations once the VMware image has started up fully, which gets tedious. I'd like to be able to mount them automatically when VMware is started.

I generally double-click the .VMX file (which is associated with VMware Player) to launch the virtual machine, but once it has finished loading I would need to run the mount commands manually or execute a bash script that does it.

Is there any way you can think of to have it done automatically? One way I can think of is to start my virtual machine by running a script that starts VMware player, sleeps for a minute or so, then runs the mount command - but setting the right sleep interval would be difficult because this varies a fair bit - and overall, it's a solution that's kinda icky and that I'd like to avoid if there's some better option.

General :: Machine Act As Both A Wireless Client And Access Point Simultaneously Using A Single Physical WLAN Interface?

Jun 23, 2010

If I have only 1 physical WLAN interface, is there some hackery that can be done so that it can be a client of an existing access point and at the same time also act as an access point for other clients? I have an existing 802.11g ADSL router, and I'm going to be building an HTPC which will have 802.11n. My laptop also has 802.11n, but at the moment it only connects at 54Mbps because thats what the AP supports. I'd like to be able to have the HTPC be a client of my ADSL router, but have my laptop be a client of the HTPC, so copying files to it will be faster.

OpenSUSE Network :: Configuring Mail / Web Server With A Static Ip?

Aug 29, 2010

I think that i lost my memory, because i completely forgot how to accomplish this.

I have a WEB/MAIL server configured to work on a static IP address, lets say 200.11.22.33.

Now I wanna point a domain to that server to get the services up and running, lets say mydom.com ...

The static IP Address is assigned by my Internet Provider.

I'm lost in the part of connecting the domain with the server.

I have the domain DNS pointing to the ISP name servers, but I don't remember if this is the correct way, or if I have to setup my own DNS server.

Software :: Configuring Fetchmail - Mail Server Setup

Aug 6, 2010

I have Ubuntu and I want to setup a mailserver. I use fetchmail to fetch mail But I wanted to configure fetchmail with fetchmailconf. I know, I can edit the configfile, but I wanted to use fetchmailconf. According to the man of fetchmail, fetchmailconf is very handy.

In synaptic, I installed fetchmail 6.3.2.2Ubuntu2.3 and I wanted to install fetchmailconf 6.3.2.2Ubuntu2 : well it didnt work
fetchmailconf 6.3.2.2Ubuntu2 needs fetchmail 6.3.2.2Ubuntu2. So, no worries: I searched the internet for fetchmailconf 6.3.2.2Ubuntu2.3, but I couldn't find any. Same with fetchmail6.3.2.2Ubuntu2

First of all, I want to flame synaptic for supplying 2 different versions for 2 pieces of software that only work with eachother.
Second: where can I find 2 matching versions? Or fix synaptic or maybe someone has a really cool solution?

Ubuntu Servers :: Secondary Mail Server And A Mail Gateway/relay?

Aug 3, 2011

Our primary mail server is Exchange 2003 Standard on Windows Server 2003 Standard - don't shout at me; I inherited it already set up this way.I have a couple of hardware identical redundant servers (HP ML350 boxes), all with very fast 2 or 4 disk arrays, multiple core CPUs and plenty of memory, and I am looking at two potential new additions to the infrastructure.

A secondary mail server is high on my list of priories. I've been well and truly bitten by Exchange in the past and given that this particular box has been running four years straight and that it's mail store is dangerously large, having a secondary mail server in place suddenly makes a lot of sense.

A new Exchange 2010 box is currently being set up, but the secondary mail server will remain in place even when the new Exchange server is brought online, so this won't be a wasted exercise.... I also want a gateway box in place to filter and relay mail to the primary server, or to the secondary server if the primary is unavailable. Currently our outer perimeter is:

ISP supplied CISCO router
Draytek VigorPro 5510 UTM

Untangle running in bridged mode (primarily used for SPAM filtering, URL blacklisting, and very little else) Exchange 2003 sits behind the Untangle box. This is how I want to end up:

CISCO >> Draytek >> Ubuntu gateway >> Exchange/secondary mail server

I know I could replace/remove the Draytek but I want it to remain for several reasons, including lots of VPN dial-in users already configured and that it offers us an additional layer of email antivirus scanning before things hit the Exchange box. No point switching all of our remote workers over to new tunnels unnecessarily...

I have done some research and have started testing a pilot secondary mail server using Ubuntu/postfix DNS is properly set up and MX records and reverse PTR records are all present and correct, and things are looking encouraging so far. Before I go out over deep waters and start to flounder, has anyone who has done something like this got any obvious howlers I should be looking to avoid ?

Two exchange servers internally. One is setup for example.com (192.168.1.10) and the other is setup for example2.com (192.168.1.20) Both are behind a single public IP.

I want to use postfix to sit in front of the two exchange servers. Postfix will accept mail for both domains and relay to the appropriate server. I have postfix installed with only defaults at this point.
