Dealing with Intruders? 656

drakyri asks: "I've been running a server for a small company for a few months. Recently, the number of attempted intrusions has jumped from about one every week to several per day - and these are only the really obvious attempts, like idiots who try to log in as root from the outside. The problem is that I'm not sure what to do about this. I've got their IP addresses and can usually tracert their ISP's - is there an accepted type of letter to send them without seeming like one of the corporate cease-and-desist gnomes?"

Formats for Electronic Forms? 38

Bifurcati asks: "I'm a grad student at the University of Queensland, Australia. I am frequently required to submit forms (e.g., annual reports) which are sent as Word or RTF documents and must be filled in electronically. However, these are almost impossible to use under Linux (e.g., StarOffice) because the tables and formatting are just too complicated and get mangled. Even Word for Mac sometimes has problems. Can anyone suggest a better, cross-platform format? Could PDF files with forms do this? What are the costs & learning curve? User friendliness is vital for both admin and student. Alternatively, can anyone suggest ways they could make their Word files more compatible across platforms?"

Deleting Old Windows Update Uninstall Files? 61

Frozen-Solid asks: "With the release of Windows XP SP2, I got to thinking about how all of these windows updates leave their uninstall information 'just in case' you need to uninstall them for some random reason. However, after you've had them up and running for a few weeks/months/years and no longer need that backup information, is it safe to just delete those ugly hidden directories from the Windows directory or is there a 'safer' way to free up that wasted space? My current update backup collection is totaling over half a gig which could easily be better spent elsewhere."

Cygwin in a Production Environment? 111

not-so-anonymous Anonymous Coward asks: "I'm working for a company that does all of its programming and script development in a Unix environment (90% of our work is either Bash or Perl scripts that communicate with an Oracle database). We've recently gotten a new customer and for reasons beyond our control, the server must be a Windows box. Since we want to reuse our existing scripts that we've spent a considerable amount of time developing, we're looking into Cygwin as an option. Has anyone run Cygwin in a production server environment for any extended period of time? If so, what were your experiences with it?"

Free Software for Cybercafe Management? 30

SantiagoRoza asks: "Hello, Slashdot. I am asking for your collaboration because someone I know needs a software to manage his (small) Internet cafe. Ideally, we're looking for software that is free/libre and multilingual (with a Spanish version), but I'd gladly take free/gratis and English-only. Additionally, the software has to work on Windows. After searching the 'net, I've only been able to find CafeTimer, which doesn't impress me. Nothing else out there looks like it will support more than 2-3 computers. Might you all have other suggestions?"
Data Storage

What is the Ideal Low-end NAS Solution? 45

Mark asks: "As demand for storage continues to grow and prices continue to drop, network attached storage (NAS) devices are popping up everywhere...from large enterprises to restaurants to small offices and homes. Several vendors are now offering low-end NAS solutions targeted at SOHO users, with varying results. Most of them are just standard PC components and standard IDE hard drives running Linux, but the price tag on these often far oustrips what one would expect to pay for the parts. Hence, people all over the world (myself included) are building their own NAS machines at home at a fraction of the cost. Beyond support for RAID, CIFS, NFS, HTTP, and FTP, what would the ideal home NAS operating system include? And more importantly, what should it leave out to avoid conflicts, security vulnerabilities, and instability? Are there any Linux/*BSD/other distributions out there optimized specifically for NAS applications? What does the ideal NAS distribution look like to you?"
Software

Where Did Affordable OCR Go? 79

Goeland86 asks: "Has OCR (Optical Character Recognition) died down? Where have all the magical programs that translate your handwriting to office compatible files gone? Most of the windows programs nowadays are either expensive (ReadIris Pro 9 about $400) and not that many OSS projects for OCR have released a recent update (Kognition was last updated on July 17th 2003 according to Freshmeat). Has everyone already scanned/translated all of their paper files? Has OCR outlived its use, or is it just a fancy technology that hit a dead end in terms of the market? Have Slashdot readers used it? If so, are you still using it? If not, why?"

Thin Client Solutions For Libraries? 502

phatlipmojo writes "I'm a librarian in the process of opening a brand new small public library from the ground up (literally; we don't even have a building yet). The library director and I are considering our options for public computing terminals. Having experienced the frustration of dealing with Dell machines running Windows XP on a daily basis, we're trying to consider other options, and we've been talking about maybe using thin clients. Have any of you used or worked in a library (or similar environment) that uses thin client stations for public computing? What are your impressions? What are the perks and what are the drawbacks?"

Know Your Enemy, 2nd Edition 103

Ben Rothke writes "Within law enforcement, establishing a modus operandi is one of the crucial things that can make the difference between finding a criminal and not. For example, a daylight murder with a single bullet to the head is quite different from finding a decapitated and mutilated body in a ditch. While both victims are equally dead, the manner of their deaths is radically different. So too with computer crime; knowing the modus operandi of the attacker can mean the difference between finding the perpetrator and not. In Know Your Enemy: Learning about Security Threats, the members of the Honeynet Project have written an excellent security reference that can enable one to begin to understand the motives of those who are attacking and compromising their systems." Read on for the rest of Rothke's review.

Passwords - 64 Characters, Changed Daily? 645

isepic writes "It seems over the past few years that the password requirements have changed - each time making it even more difficult to crack. My company just changed its password requirements from 180 days down to 90 for most servers and from a minimum of six characters up to eight. So, as parallel processing computer clusters gain in power according to Moore's law, how are we expected to change them in the next 2-10 years --- and how often?"

SciFi Channel To Air A New Galactica Series 175

EvilBuu writes "The Sci-Fi Channel has begun airing ads announcing a full Battlestar Galactica series following the surprisingly (to some) good new mini series starring Edward James Olmos. Looks like it will be a straight forward continuation of the mini, with the same cast and more Cylon goodness!" According to this press release, Richard Hatch will guest star, and the show will air starting in January 2005.

2.4GHz-Friendly Phones? 386

da3dAlus writes "When I first bought my 2.4GHz wireless phone system several years ago, it was a rather new technology, and wi-fi wasn't even on the scene. Now it appears that all wireless phones are on the 2.4 or 5.8 GHz spectrum, and I've got neighbors with wi-fi (with myself included). While checking out new phones recently, I've noticed some are carrying a "802.11 Friendly" sticker. The question is, are there any trully 802.11 friendly phones? Has anyone really ever had a problem with these types of phones interfering with their wi-fi network?"

How Powerful is the Turn-Off Power of Spam? 114

JayBonci asks: "Here's a question to the Slashdot readerbase. How powerful is the turnoff power of spam? With an upcoming political election in the United States, and a nation not very-well defended against mass unsolicited emailings, what kind of anti-marketing medium is spam? Could a spammer push out millions of: 'V0te for G3orge W. Bush!' or 'J0hn Kerry for Presidnet@', in the hopes to turn off (or on) voters. Spam marketing penetration is terrible (I've heard figures like .001%), but how powerful is its anti-marketing capabilities? An interesting discussion for the Slashdot audience." How often do you make the decision to NOT buy something form a company because you know they engage in spamming activities?

Managing Huge Networks with Open Source Tools? 45

An anonymous reader asks: "I work for a large multinational firm with a network that spans the globe and am responsible for evaluating the software we use to monitor our network. Our department has a lot of money, and we're usually willing and able to spend it on good commercial software. Recently though, I find myself evaluating and approving more and more open source software. We are actually in the process of replacing some of our commercial tools with software like Nagios, LooperNG and syslog-ng. We are also evaluating MRTG, RRDTool, ntop and a host of other tools. The problem is that there's just too many of them, most of which are not maintained anymore. Here's my question: What other open-source tools do you use to monitor your networks? I not just looking for names, but how long you've been using them for, how easy / hard is it to administer and I guess how well it scales as the network grows. More importantly, are their respective projects still alive and kicking?"
