The original poster did not comment on the delivery for grading: does the professor need to see it 24 x 7, or just fire it up, run the demo in the office, and then leave?

I have had to do various things similar to this in the past, and as a result, have a Mac laptop with lots of RAM, and simulated the machines with Virtual Machines. Not worried about security in this case as VM Hypervisors like Virtual Box or Parallels can create networks that live inside the machines with virtual interfaces. The VM can see each other, but not the real world.

Anyways, I generally use Linux for the backend, and either Mac or Windows for the front. Couple of Virtual Machines, and can backup the hard disks if desired if you want to keep snapshots of code or whatnot.

My latest project involves FreePBX and a telephone server running on a Virtual Machine, and working with the phones to demonstrate to a customer how the real thing will work.


WIndows 2003's DHCP panel should show you the active leases, and from there, you should be able to determine who/what is consuming them.

It also sounds like you are a business. Take the time and move everything off of the 192.168.1.x subnet, as eventually, someone will ask you to VPN one day, and have that same subnet at their home, and that will create a routing nightmare. Change yours to or something else off the beaten path, so you have some routing flexibility.

I agree to also examine your lease expirations, and have things clean up from there.

Also, Windows 2003 is no longer officially supported by Microsoft. Might be time to upgrade that server.



I agree that an OpenVPN tunnel is quite snappy on a single 1194 UDP port forward from your firewall. Yes, it requires a client download, but you can really trim down access on the VPN, and beef up security with different features, including the ability to protect against man-in-the-middle attacks.

PPTP was developed back in the days of Windows NT, or the 1990's. There are problems with the protocol, some of which are discussed https://www.bestvpn.com/blog/4147/pptp-vs-l2tp-vs-openvpn-vs-sstp-vs-ikev2/

As for general troubleshooting, you can use a packet sniffer like Ethereal / Wireshark to see if packets are reaching your server on the proper port or not.



If you want to get deep into mail processing, scrap the windows box, and go with a linux solution, such as CentOS, and learn postfix. Then, as you continue learning about email, look at the MailScanner package which will send you into the world of antivirus scanning, blacklist scanning, and other spam fighting techniques.

Also note that POP3 on 995 is POP3s, or the ssl encrytped port. You will need some sort of certificates to get that to work.

I would also study IMAP as it is a cleaner multi-device email protocol. POP is nice if you have a single user checking from a single box. IMAP is much cleaner for multi device checking... computer, cell phone, tablet.


Hello All,

I have to wonder if in all the legalease crap we "agreed" to, even the stuff written in French, when the software was installed allowed Micro$oft a legal in to upgrade the machines with our implied consent.

All of the machines that I care about are on a corporate network, serviced by a WSUS server. It might boil down to overriding DNS to look at localhost for .microsoft.com to prevent the download.

There is nothing wrong with "if it works, don't fix it". A computer is a machine, dammit, and if all I want it to do is perform in a certain fashion, then so be it.

Funny, my Macs and Linux machines work just fine and don't have these problems. Slowly converting people away from the Micro$oft madness.

Shall we talk licensing models, and CALs sometime?


Before you attempt the upgrade, you may wish to ask yourself if it is really necessary. I find myself prefering Mountain Lion over Yosemite, and my computers are nice and stable. I find little motivation to upgrade if things are working exactly as I wish them to.


No need to pounce on him. OS X will display the running processes in a terminal window, or you can go to Applications -> Utilities -> Activity Monitor, and view information there.

Not sure about controling the Startup Daemons (we call "services" the Unix "daemon") as I have not had to dinker with them.

You can get some startup items for a user login to be controled in the System Preferences -> Users & Groups -> Login Items area.

I like the older, modern MacBooks with the Dual Core processor. Strong enough to move along quickly, but will still run Snow Leppard. SL was the last OS X that could run Carbon applications... so now on my Mountain Lion computer, I cannot run Diablo II as it was compiled with Carbon, and ML does not support that anymore.

The older Macs also will not CHARGE an iPad. They will sync and work with iTunes, but they did not have enough USB power capacity to charge them.

The one thing I DISLIKE about the latest MacBook Pro, the Retnia one, is that they removed the ethernet jack. As a computer professional, I want a strong OS like MacOS (which is a flavor of Unix), but I cannot assume wireless networking will always be available. Yes, I can get a Thunderboldt to Ethernet adapter, but that is just another widget to carry around, or worse, loose.

Hello. Just to understand, this is a USB external hardddrive that is not working in either your Mac, or on other computers. Disk Utility is Apple's authorative program to work with devices.

Have you tried a different USB cable?

You tried it on different computers without success, so it is either the cable, or something internal to the unit.

Wowsers! Cannot use a VM to accomplish this.

The following I haven't tried, but is the approach I would take:

Format the drive completely empty. Install each Linux to it's own partition, and keep track of which one was done first. I would do Ubuntu first, then OpenSUSE, and then Fedora. Make sure you do an advanced install, or at least have the option to customize your hard drive layout. Each one would only need to be say 20 GB in size... Have the Fedora partition write to the master boot record.

Once everything is installed, you should be able to either run a rescue / repair disk, or boot knoppix, and edit the /boot/grub/grub.conf and define each bootable partition. Make some meaningful descriptions. You will need to do this if you
install Windoze last, as it will clobber anything that grub setup.

Next, you need to edit your grub.conf file to ensure each partition is properly listed. Note the root (hd0,1) area... that is hard disk 0, partition 1. You will need an entry for each linux version (hd0,1) (0,2) (0,3) but properly aligned.

My /boot/grub/grub.conf has these lines:

title Fedora (version)
root (hd0,1)
kernel <bunch of stuff>

title Looze XP
rootnoverify (hd0,0)
chainloader +1

Postfix is a back-end email manager, like Exchange Server or Sendmail and not a front-end like Thunderbird or Eudora.

You may wish to also consider why you want to violate your terms/contract with your ISP.

Also, setting up another email server may not be as easy as you think. Yes, the technical software of an email server is easy to get and install, but email follows definitions bound in DNS records (specifically the MX record) and a number of us system administrators check each email message, and look for a defined MX record. If you don't have a valid email server address, and other pieces put into place, your message gets marked as spam, and eaten. If you do too much of this, other consequences, such as being blacklisted by an organization, can get you into real trouble.

Oh, that is a loaded question, right up there with differences among the christian religions, or explaining chocolate and strawberry ice cream.

Unix was developed by a group of AT&T employees at Bell Labs in 1969. From there different groups have done different things with it.... see WikiPedia for details.

Linux was created by a Computer Sciences student Linus Torvalds in 1991. His release of a kernel (core code) happened in the early days of the internet, which allowed talented programmers to look into it, and write things against it (meaning, link into the core, such as a device driver for a keyboard that the kernel could process), and Linux was born. See WikiPedia too.

I am of the opinion that Linux and Unix are quite related, but there are some important differences. To end users, they may feel the same, but notice that file structures are different (is that config file in /usr/etc, or /etc) and differences in what sorts of software is available. You may say that they are like flavors of ice cream... basically the same, with different tastes.

Mac OS X is a flavor of Unix. Apple has a special GUI interface running over the Unix. Apple might be mint chocolate chip ice cream.

Windows is not a flavor of ice cream. It is more like a cookie. Tastes good for some, but leaves lots of crumbs all over the place.

Both Linux and Unix have different codesets within them, called distributions (or distros). Linux has ...

You may wish to give VirtualBox a spin. It is freeware from Sun, and you can install using .iso or real physical disks.

I agree that VMWARE should be able to do this, but perhaps VirtualBox may give you the desired result without the headache.

This is one of many fundamental reasons why it is a bad idea to use the Administrator account as a daily user account. Imagine having to delete it, or cleanup something like this.

I ran across such a case a couple months ago, and it was a headache converting from Administrator to a user with administrative privs.

You may need to use a command line operation to disable DHCP on the Juniper network router. Some of the CISCO products also require usernames and passwords to get to an administrative level to make a change.

You will need to clobber one of the DHCP servers, otherwise the scopes could clash and cause problems.

Does your assignment require you to physically install three operating systems, or can you prepare 3 Virtual Machines, and call it done?

You may wish to check with your professor, but in my opinion, you would best off picking a base operating system, in your case unfortunately Windows 7, and from there, install a virtual machine program (Virtualbox is free) and from there, setup three virtual machines.

Choosing Ubuntu, Fedora, and OpenSuse will expose you to the three major distributions... Debian style (apt-get), Fedora-Redhat style (yum), and OpenSuse (yast).

You might even be able to earn bonus points if you have enough RAM, and run all three operating systems at the same time. If you create a shared folder, you might be able to have all three see a sharepoint, and exchange files among themselves.

I am listening to a mix of music from a variety of artists. Right now, Couch Potato from Weird Al Yankovic is on tap.

Hello Kerry,

Welcome to DaniWeb! I am a member of the ancient school here, knowing Dani for 6 some years. Yes, some things have changed, but a lot of good quality people remain around.

I think you owe Dani dinner for not making an account before now. Look in Dani's Cookbook for some ideas. :)


For those who may not have heard, former network leader Novell (who owns SuSE Linux) made a deal with Microsoft exchanging some intellectual property rights. Those in the business-end of IT know that Microsoft is busy applying for thousands of patents concerning Intellectual Property -- have a look at Network Computing and Information Week for all the good details.

From Groklaw:

Under the Patent Cooperation Agreement, Microsoft commits to a covenant not to assert its patents against Novell's end-user customers for their use of Novell products and services for which Novell receives revenue directly or indirectly from such customers, with certain exceptions, while Novell commits to a covenant not to assert its patents against Microsoft's end-user customers for their use of Microsoft products and services for which Microsoft receives revenue directly or indirectly from such customers, with certain exceptions.

What does this really mean? Novell won't sue Microsoft? Microsoft won't sue Novell (SUSE) users?

Look here for some great information / discussion:

Also, check out:

So, will Microsoft start distributing SuSE? Will Novell be finally crushed by Microsoft? How will the GPL (General Public Licence) of the core OS be affected? Are we looking at a new big legal case like SCO vs. IBM? Yes, there are a load of questions asked, and many answers that need to be generated.

So what do I think?

  • I'm done with Novell. I have a certification from the NOS of yesterday, and while I find parts of Netware to be ...


You are absolutely right concerning the risks of equipment in the cargo hold of the plane, along with the value of meeting and networking with people. Doing the webcast is socially isolating -- networking with people is an important task, and visiting with others, getting in on the action -- that is the real magic of conventions.

Perhaps you should bring along a legal pad and a pen. Maybe two colors to make it fun. Or try writing with your other hand for a different "font".

The most important thing is that the travelers are still alive. Yes, there was tremendous waste of soaps, drinks and the like. But until the Terrorists loose the blind thirst for blood, I am not certain what other choices there are.


I love my MacBook. :) Couple months old, but I still consider it quite new, and as more and more Universal programs come out, it will get faster and more enjoyable.

As for the super-computing, you need to have software that will take advantage of it. Weather simulations. Large Database queries / sorting. Video Processing.

Have to remember that with all 8 CPU's spinning at 2500 MHz, and all you are running is Word, just think of all of the idle clock cycles that you and your local power company are sending out in smoke.

Network Computing recently ran an intense report on too much power/heat within the data center. Computers are becomming more dense (8 CPU's in one case, instead of one or two!). Heat. Lots of it. And Power. And then trying to cool it. Basically, the electric bill, and the cooling requirements are much larger than the machine cost.



Let's say for a moment that Microsoft made cars. Would you expect there to be parts for a 1998 Microsoft Sedan?

I would. But then again, I would also acknowledge that the part may need to be ordered, and there might be a handling fee on it. But I would expect to be able to get it. For cars, I would suggest 20 years to have parts available. But not necessairly for free.

At some point, the 98 folks are going to need to move forward. Either retire from the internet, or build up a defense paradigm.

As for my private consulting thing, I won't work with 98 anymore. I am not going to go looking all over the etherized tundra for drivers and the like.

As for business applications, I know of a handful of 98 computers used on specialty devices isolated from floppy disks and the internet. They'll be fine.



I fully agree with you. I have the 15" MacBook Pro, and love it very much. I do wish, however, that the thing came with a modem and S-Video outputs. These items my PowerBook G3 from 1999 has, and they are still used by me.

I do not know if the DVI video adapter can have a widget to format the signal into S-Video. As a techie, the need for a modem port is still important to me. There are still places in America that Wi-Fi and cable does not exist. Yes, I know there are USB modems available, but I see that as another part that can break or fail.

Otherwise, the machine is outstanding. It can get a bit warm though, so be sure to keep it cool.



I can just think of all the obsolete computers that are going to be turned over, and how wonderful Linux will operate on them.

Yes, some of you are really going to need Windows to satisfy your computing needs, but I am willing to bet that the mass majority out there could run Linux, and save yourselves a lot of money.


A couple of years ago, I thought I would never have seen an "Intel Inside" sticker on Apple hardware. Looking at the news today, I was surprised at the revelation that Intel Macintosh hardware can now run Win XP SP 2!

Somebody please check if hell froze over.


Go look for yourself: [url]http://www.apple.com/macosx/bootcamp/[/url]

Apple has made it so easy! You need to make sure your firmware is up to date, some hard drive space, updated OS software, a blank recordable CD, and a legal copy of Windows XP.

What is really the easy part of all of this is that Apple has taken the hard part out of running Windows by automating the following things:

  • The blank CD that the instructions call for is used to store drivers needed in the Windows XP world. Bootcamp supplies all the necessary drivers -- your Windows friends often have to hunt them down on the internet from a variety of places. Your drivers are right where they are needed -- in your hand.

  • Hard drive partitioning is an easy step. Windows XP is going to run in a different area of the hard drive (called a partition) than your Mac OS X. Reading through the online documentation, you can access your XP partition from OS X, but if you made XP use NTFS, the drive will be read-only from OS X. Also remember that Intel Macs will not run Classic, so questions about OS 9 reading XP are moot.

Bear ...


Good comments fellas. I agree about not wanting to dual-boot the Mac, unless it was an older one, such as my Powerbook G3 333 MHz computer. An OS X box that is sufficiently modern / fast that can run OS X is a cool useful thing.

In the case of my PB G3, however, where OS X is marginal, Linux feels nice and refreshingly fast on the computer. Fink is not a complete answer; for example, the current version of NESSUS is not available via the fink options. As the latest release (3.x) is not open source, you cannot compile it. Only available for Fedora / Redhat and Suse as .rpm packages.

It is possible to live without Windows. Been doing it for a few years now. With OpenOffice and other tools available, I found it easy to let go. Granted, with Linuxes like FC5 and SuSE not shipping with xine and xmms ready to go (because of licensing issues) there are a couple of post-install steps that the end user may not be ready to deal with.

The last "difficult" install that I remember for Redhat was 5.2, when .iso disks were not easily available, and we all installed from the internet. It was saying something to install your OS via dialup internet.


Fedora Core 5, the next version of software based on RedHat Linux of long ago, was released in Mid-March to the masses. I am sure that others have looked at the alpha and beta releases -- I waited until the the official release before looking at the software. Initial reactions: I love it.

My hardware, for those to compare, is an AMD Athalon 1.2 GHz computer with 756 MB of RAM or so, ample hard drive space, and an ATI Rage Pro 128 video card. Actually, it is an ATI All-in-wonder TV card, with Rage 128 video horsepower, but the default system install doesn't recognize the TV input. For this review, I have not tackled the configuration of TV video.

I found the disks easy enough to grab via FTP off of a mirror, and burn. I like the DVD distribution -- just one disk to be responsible for, and I can click and go with the install, and not have to be around for the disk-swap. The FTP'd DVD worked well the first time, and the install process worked wonderfully.

As an advanced user, I never select the automatic disk partition scheme -- I always partition the disk out into 8 or 9 partitions, one for root (/), /var, /home, /opt, swap, /tmp, /usr, and /backup. Granted, /backup is not a standard, but I make it a distinct partition for backup purposes, and develop crontab scripts (batch files for our Windows friends) to make copies of the files onto ...


I agree with Dave... Wireless security is hard to come by, and WEP is not sufficient. It can be hacked, scanned, and thumped without too much effort.

You might also be able to limit the exposure of the network by placing the access point in the basement, and / or toggling the transmit power to the least available. I know that on my Buffalo Technology's Access Point can change the output power to something very minimal. Placing the node low to the ground limits the range.



I have not tried the F8 trick on the keyboard to do that. There are some symbols up there that I am not sure what they do to be honest. Have not done everything just yet.

I also found out that I needed to run FONDU under fink to migrate my fonts over into OpenOffice. I wish that was in the OpenOffice literature.


As many of you already know, Apple has released a new line of computers with Intel chips inside -- namely the new iMac, and the MacBook. I took delivery of my new one the last week of February, and it was a wonderful new tool to take me into the next line of computing.

My new MacBook came in a nice styrofoam box that was thinner than the one I purchased back in March of 2000, the bronze Lombard PowerBook G3. The unit ships with 2 DVD-ROMS for system restoration.

On the outside, the laptop is nice and sleek and thin. Because of the wide-screen format, the MacBook is wider than my PB G3, and as a result, the old computer bag is not going to work for me -- the bag's foam innerds are in the wrong places to protect the MacBook. I like the new magnetic power connector -- it is great in preventing the power cord getting trapped in the computer where it could break the female plug inside the computer. I do not like the power transformer on the other end though -- I think Apple went backwards from the "hockey-puck" power adapter that was released with the Powerbook G4 series. I find the MacBook power transformer to be clunky, and the wire management more messy than the hockey-puck.

Other exterior items include the video out port, 2 USB ports, the 10/100/1000 Ethernet port, and Firewire (400). Apple deviated from the PCMCIA card standard with a ...
