There is an old but proven way: Use an old analog modem. Here is how Connect the modem to the server via serial port (e.g. ttyS0) Plug the modem's power supply not into the UPS, but directly in the mains Do NOT plug anything into the modem's phone line Now poll the modem every few seconds sending ATZ[Enter] and expect OK[Enter] - if the modem does not ...

The way the question is asked is pretty confusing, but if you can copy from your local machine to the server, to go the other way just flip the command line order. its scp [from] [to] scp user@homeip:/path/to/file /local/path/

Snapshotting a filesystem is an amazing feeling, as geeky as that sounds. Knowing you can roll back in an instant is a relieving thought. Snapshots also take only a few seconds. A colleague and I recently deployed an OpenSolaris NAS for a smallish college (200+ students) for virtual machine iSCSI storage for Citrix XenServer, student file storage and ...

A ups usually comes with an USB or COM1 connector. When you connect this to your server you can then start monitoring the UPS. In a windows environment, without installing the software, the messages are already registered, and it will shut down the server for you. I don't know how this works on linux, but I bet there are some software packages available to ...

For a small home-server with low-traffic, I'd just buy a regular old PC, or recycle an old laptop. I've got a 5 year old laptop that sits humming on the shelf serving out media and more. Works well, costs next-to-nothing.

NB: You either need to be logged in as root, or use sudo to do all this... Use your favourite editor to create or edit /etc/mdadm/mdadm.conf file as follows: If the file does not even exist, paste the following into the new, empty file: # mdadm.conf # # Please refer to mdadm.conf(5) for information about this file. # DEVICE partitions # auto-create ...

Subversion is mainly used as a source control system, therefore it's main intend is not to version binary files. What advantages do you see in using Subversion for keeping your System in Sync (i would find it terrible to always having to keep Subversion meta information in my normal files and managing that could become pretty annoying)? Maybe a backup tool ...

There is software RAID built into new versions of Windows and Linux. Have you considered just mirroring a drive for RAID1? I'd like to add that simply mirroring a drive does not provide an adequate backup solution. Data corruption can render that setup useless very quickly and with little-to-no warning. If you're looking for a backup solution, I'm ...

Absolutely; this is called a headless system. So long as you can get it to boot into a live distribution of Linux, you should be able to remotely configure the server via remote shell/terminal. If you wish to use the current operating system, your only choice is to hope you can navigate without a graphical display. If you choose to use a live distribution ...

A good UPS also does power-conditioning, which will help prolong equipment lifetime. All too often, when power returns from having been down there will be a transient surge followed by a transient under-voltage, the kind of cycling that can reduce the lifetime of power-supplies. A high quality surge-suppressor can clamp the surge, but the undervolt can only ...

Picasa for Linux should have these functions Check this link for a feature list: Sync your Picasa 3 and Picasa Web Albums edits Tired of having to manually re-upload your photos after making further edits? By enabling 'Sync to Web,' edits made to your photos in Picasa 3 are automatically transferred to your corresponding online albums. Retouch your ...

If by NAS you mean (Open)Solaris or FreeBSD on PC hardware acting as a fileserver, then yes, it should be fine. See this question on building your own NAS. You might find dedicated NAS software such as FreeNAS easier to setup and admin.

Your two options are to move the devices to another computer or to the network itself. For the HD, you could: get an external HD enclosure for the 1TB HD and attach it to another computer or simply move it to another computer internally For the printers, you could: attach them to another computer get a "print server" (essentially a wireless ...

The biggest problem is that out of the box its not locked down very tight. From Wikipedia: Officially, XAMPP's designers intended it for use only as a development tool, to allow website designers and programmers to test their work on their own computers without any access to the Internet. To make this as easy as possible, many important ...

OpenBox and Fluxbox are not server management GUIs, they are Window Managers (WMs for short), they will give you some ways to enjoy the use of your mouse, but they won't provide any tool to administer a server. You will soon realize that a Gnu/Linux server is administered through text files, a graphical text editor might help, but it's easier to use the one ...

I think just for the "services" google will provide: Bandwidth, redundancy, energy to power the darn things.... it is a no-brainer to use Google Apps (or some other hosted email quite frankly). My opinion: Unless you have some strong need to keep your email locally managed (say HIPAA regulations or something similar) - you are better off having it taken ...

What you are probably looking for is a standard NAS enclosure such as this one from Western Digital (There are thousands of NAS devices!): If you want redundancy, take a look at a NAS device that supports RAID (Nearly all multi drive NAS's do this, but some a lot better than others): Or, if you have USB hard drives, you can get a device like this: ...

FreeNAS or OpenFiler Both are designed for sharing files and both are free. I use FreeNAS, it is easy for me and I like the features. I say give them both a try.

OpenFiler and FreeNAS are the two that spring to mind. If you want more info on making a decision, these questions might help.

Many consumer ISPs block port 80 so that consumers can't do their own web hosting. You might want to check with your ISP to see if they are blocking it.

Server 2008 is analogous to Windows Vista. Server 2008 R2 is analogous to Windows 7. Datacentre and Enterprise are the same OS (just different license agreements), Standard has 95% of the features of Enterprise, and Web is strictly for web hosting, nothing else. HPC is definately not the one you want. For 99% of stuff, "Standard" is fine. You can see a ...

PCI/PCI-Express (aka PCI-E) slots let you install expansion cards. Expansion cards give your computer additional capabilities. Some very common expansion cards were sound cards, 56k modems, and Ethernet adapters. You don't have to populate your PCI/PCI-E slots, but it is an option if you need to extend your hardware. Since the introduction of the PC in ...

If the laptop is on AC power 24/7 and also has a battery (to keep it running during power cuts), will the battery be damaged? No, but if you want you can remove the battery and run the laptop with only AC, if you are concerned about battery wear. Overheating is clearly a potential risk, as several people warn against. Is there any other risk to ...

From supermicro's page for that model For Single CPU: Memory must be populated in CPU1 DIMMs only For Dual CPUs: Recommended that memory be populated equally in adjacent memory banks I do believe modern processors have their memory controllers on die, so this makes a lot of sense. Even if it didn't, it would be a lot more complicated to ...

I find 'localhost' easier to type, fewer keystrokes! It gives you a chance to imagine life before TLDs! To accomplish what you're asking, you can add a line to your Hosts file like: 127.0.0.1 example.com This would skip DNS lookup for example.com and go straight to your local IP. For the location of the Hosts file on your system, check out the ...

Your SATA controller (probably integrated in the motherboard) may or may not support this feature. It's likely if you're dealing with a new motherboard that it does. Basically, older motherboards supported something call IDE emulation rather than using native SATA Advanced Host Controller Interface (which does support hot-swapping). From the Wikipedia ...

I built my own and bought a copy of WHS as soon as I could. That being said, I wouldn't do it that way again. I'd buy one of HP's machines - and that's what my friend did when I recommended it to him. HP has put some neat stuff in that adds value to WHS and it was a lot simpler. I spent a lot of time doing setup and discovering, for example, that the ...

When in doubt, Ubuntu is a good choice You could use the Ubuntu Server Edition too Commandline connectivity would good be over SSH. A new Ubuntu edition is about to be released (9.10, Karmic Koala) But, if you start soon I'd suggest you start with the Jaunty 9.04. You may want to read up the time based releases page for Ubuntu. Consider a multi-partition ...
