RE: Highly OT: I request your objective opinion
by Kelsay, Brian - Kansas City, MO 15 Mar '06

Those not interested, delete now; others read on. Umm, first off, this does not appear to be religious in nature, so what was the point of bringing this up? So you thought Michael Moore was a nut-job? This guy is just as far out there in my opinion. I like how he blocks out the sound of what is really going on to blather on and on about a police state. Sounds like he is saying that someone in our government purposely let more than 3000 people get killed, just to have an excuse to go to war. I find that highly suspect. What I can tell you is that I personally noticed several years before 9-11-01, that certain access points were completely ignored by security, other than having a card-key door. I witnessed several people, apparently baggage handlers and pilots, going thru side doors in the airport at KMCI, St. Louis, Atlanta, Denver, Las Vegas, LAX, Chicago-O'Hare, Ft. Meyer's, Dallas and at least a couple others. That is EVERY airport I've been in. If anyone LET this happen, it was the airlines and the airport facilities management staff and their lax security procedures. Years before 9-11-01 we had Die Hard and Die Hard 2 and Nelson DeMille's "The Lion's Game" http://www.amazon.com/gp/product/0446608262/002-4878195-6655223?v=glance &n=283155 <http://www.amazon.com/gp/product/0446608262/002-4878195-6655223?v=glanc e&n=283155> <http://www.google.com/url?sa=t&ct=res&cd=1&url=http%3A//www.amazon.com/ exec/obidos/tg/detail/-/0446608262%3Fv%3Dglance&ei=jCEXRP25LqKepAKU_o3zA Q&sig2=bz-lnx5-oKE8asSeR-NR1Q> That said, you can't guard against or plan for every eventuality. It is impossible. Just like when trying to make something idiot-proof, the universe comes up with a better idiot. Try to make someplace theft-proof or terror-proof and a more creative thief or terrorist will rise up. Witness the shoe-bomber. Who would have ever thought of putting a bomb in your shoe. None of us in our right minds can imagine the lengths that someone would go to in order to harm others for no real solid gain. I would say that at some point they will give up on trying to hurt people, but in my opinion, they are crazy and will never give up and try to live in a society built on compromise.

OT: Needed: Camping Tents
by Leo Mauler 12 Mar '06

12 Mar '06

My church social group would like to send everyone on a camping trip in May. The problem is that not everyone has a camping tent to sleep in, and there are financial issues preventing some of them from getting a tent on their own. If anyone has a good used tent they'd like to get rid of for free, please contact me off-list. We can come pick it up anywhere in the Greater Kansas City Metro Area, and someone can pick up a tent from Lawrence if necessary. And if anyone knows a place where one can find tents for $20 or less (two person dome-style is fine), this would be nice too. __________________________________________________ Do You Yahoo!?

OT: For Sale: 17" iMac w/ 1.83 GHz Intel Core Duo, 512MB RAM, 160GB HD
by Cory Bosley 12 Mar '06

12 Mar '06

Hello KCLUG, I purchased this iMac about a month ago, but have since realized that it was a want, not a need, so I am seeking to sell it. It's completely stock with the basic specs in the Subject line; the complete specs may be found at: http://www.apple.com/imac/whatsinside.html You may go to crucial.com or another website to order RAM if you wish to upgrade it; depending on how you intend to use the computer, it could stand to have some more RAM. The machine is in great condition; the screen has some dust and the non-screen part of the case has my fingerprints on it (I can clean it with a microfiber cloth if you'd like). I did not unwrap the keyboard or the mouse, since I had my own, so those are in perfect condition. I also did not purchase AppleCare. It has something like 11 months of limited warranty left. I will reinstall the base OS so that it boots into Apple's first boot setup mode. I am asking for $1150 OBO. Please email me personally at imac(a)bosleys.org, not the list. Alternatively, if you have any suggestions on where I might sell it locally, I'd love to hear from you - I'm trying KULUA and KCLUG. Best, Cory Bosley

KC Snort site unavailable
by Russ Starr 07 Mar '06

07 Mar '06

It has been noted by a few people that the Kansas City Snort user group site is down. My web provider changed the server my account was on without informing me, so I have to get the DNS changed for the domain. Unfortunately, the domain is owned by another member of our SNUG, so I'm waiting on him to change the DNS records. The site can be found at http://russix.net/kcsnort until DNS is happy.

Kansas City Snort User Group
by Russ Starr 07 Mar '06

07 Mar '06

Hello kclug members. I used to be on this mailing list a few years ago and even went to a few past meetings. I am back on this list now and I wanted to inform you of the Kansas City Snort user group that we have formed. I figured there would be a handful of interested members here that would like to participate in our meetings or future events. We have had a couple of meetings so far and I would like to welcome anybody that wants to join our mailing list, our irc channel, or come to our meetings. We are just starting off and our group's focus is a pretty narrow topic, so we are relatively small. We tend to discuss many aspects of network security... not just IDS or even Snort for that. We have planned our regular meetings for the fourth Tuesday of the month in attempt to respect your regular meeting schedule. I feel like I'm spamming, but our website is at http://www.kcsnort.org. Go check it out... I'm sorry to say that if you didn't go to our first meeting, you missed Marty Roesch who happened to be in town that day and dropped in for our meeting. It was definitely a treat for our first meeting! :) Thanks, -Russ

There is a Debian that works on there. I think it has a RISC processor. You might also be able to get OpenBSD, PA-RISC Linux or others that are specialized. I looked it up and it has something like a 80MHz processor. As far as RISC systems go, I don't know how good that is, but good luck. www.fr.parisc-linux.org/documentation/hp9000_models.html http://openpa.net/systems/715.html http://h20000.www2.hp.com/bizsupport/TechSupport/Home.jsp?lang=en&cc=us& prodClassId=-1&prodTypeId=12454&prodSeriesId=44239 www.openbsd.org/hppa.html >-----Original Message----- >From: On Behalf Of James R.

Re: Which wireless card?
by Justin Dugger 05 Mar '06

05 Mar '06

I have a DLink DWL-510. Its drivers are not in the kernel, but rather as a seperate install similar to how nvidia works, but with more features exposed in Open Source liscenced code. These drivers are provided by Ubuntu in the linux-restricted-modules-'uname -r' package and have worked painlessly for me during install. I'm not sure which CD you're talking about that has an executable file on it, but driver CDs rarely have any useful programs on them, linux-wise. I've had a well versed network tech for a local uni suggest that orinocco cards are fantastic. I can't remember what he said about cisco cards. But definately make sure when you pick out something that you see the device listed by the drivers you intend to use.

Re: What is the modern "Floppy-Based" router based on?
by John 05 Mar '06

05 Mar '06

http://linuxhelp.blogspot.com/2005/11/make-your-files-immutable-which-even.… I looked into a couple of things and had an idea that the link above plays into with this. What if you simply set the attributes for all of the files you wanted to read-only, set them to immutable, and any further attributes on the build system, but fail to put chattr on the router you are building. This means the files can't be removed, changed, etc on the router and if you tell it to mount Read-only for / on boot, problem solved. That would be the ulta-paranoid approach I would do. That way even if they managed to get it mounted RW, what can they change since the attributes would prevent changes and chattr wouldn't exist on the router. Another good way to ensure less issues is to minimize the system. Build it with a kernel, busybox, and the needed startup/support files for the router task. I would also suggest minimizing the abilities of apache if you decide to make it web configurable. Or look for a alternative web server thats hardened and small. -John Frakes unixengineer(a)earthlink.net -----Original Message----- >From: Leo Mauler <webgiant(a)yahoo.com> >Sent: Mar 4, 2006 10:42 PM >To: kclug(a)kclug.org >Subject: Re: What is the modern "Floppy-Based" router based on? > >The main problem with the CF card solution is that the >CF card has no "write-protect" feature.

For those programmers coming from the Windows world, you might be interested to know that an IDE with a fully integrated GUI designer will be available shorty from the MonoDevelop project. Currently only C# language features are supported but there's support for Boo, Java, PHP and Python in the works. Thus far there has been no OSS IDE with an integrated GUI designer available for Linux. The closest was KDevelop which included Qt Designer as a plugin.

Well, I think I started that email before I got any caffeine in my system. Come to think of it, I haven't had any yet today. Maybe that is my problem. I was just emphasizing the point about them being willing to do whatever it takes to get that last dollar from the customer. You gotta hand it to em. They could sell ice to Eskimos and not guarantee that it'll be froze when it arrives. A recent study I read about indicates that it is very difficult to read a person's emotional state via email or IM communication. That is why smilies and words in quotes are so helpful. We don't have the visual cues to tell us when people are joking or mad. I added the typical geek rant mode indicator, but could have easily added a tongue in cheek, gagging or some other face I was making at the time. I got in a hurry at the end however as the phone started to ring and I needed to get some real work done. Most of the time I'm ranting, I'm also laughing at the silliness of it all. >-----Original Message----- >From: On Behalf Of Leo Mauler >Sent: Thursday, March 02, 2006 11:41 AM >Ahhh, this kind of response is why I keep coming back here. >

<rant> Yes, they would. They would use cans and string as a communications device, if they thought they could get away with it. They'd use the original DivX disks that self-destruct after so many plays or time-limit reached. If they could remotely destroy PCs with pirated software, they would. If they can steal an idea or a piece of software from a small company, they will. They would and have knowingly sent out code that has not been stress-tested or checked for security flaws only to come back later and service pack it when they had time, after there was a major vulnerability found.

What is the modern "Floppy-Based" router based on?
by Leo Mauler 02 Mar '06

02 Mar '06

I was going over some of my old links (in backup CDs) and found this interesting link to creating 1.680MB floppy disks for use in floppy-based routers and gateways: http://www.trevormarshall.com/byte_articles/byte19.htm This made me think about the whole concept of the PC-based router/bridge. Floppy disks have the write-protect tab on them, making them easily switched (provided you have direct access to the PC) from write-protect to run the router, to flipping the write-protect tab for editing the router, and then flipping it back to write-protect once you are finished with the edit. What can the modern PC-based router use to duplicate this nice combination of security and ease of editing? You can duplicate the security (and possibly make it better) with a write-once CD-R, but to make changes you have to write an entirely new CD. ReWritable CDs aren't a good idea precisely because they have no "write-protect tab". The same might go for a memory key, since there is no "write-protect tab" for a memory key. I've been taking training classes with Cisco routers recently, and the one issue they all seem to have is that if someone manages to get past an interface password and then a configuration password (two words: "social engineering"), even without physical access to the router, they can change (and access) what they like. While I've been told there are ways around the write protect tab, it seems to me that having some form of physical write-protect on the media used to store configuration files would be a good idea for modern routers. __________________________________________________ Do You Yahoo!?

I have several pen drive/memory cards with a lock switch (write protect) on them. Sandisk Mini Cruzer and several MMC/SD Flash Memory cards. A CDRW is not vulnerable if there is no access to the tools to write on said CD and if the session is finalized. I use CDRW disks for writing ISOs of various LiveCD distros that I keep up with. When you write an ISO image to the disk, the session is normally closed. That means you can't write anything else to the disk until you erase it and rewrite it. I believe Puppy Linux and one or two others have a method of leaving the session open, to enable live config changes. IPCop runs from HDD, with appropriate permissions, default DENY rules, and only enough Linux to do the firewall and router thing, built from LFS, previously it was a stripped older RedHat. Devil Linux runs from a LiveCD, with configs backed up to floppy I think. Freesco used to run from floppy only, but I think it is now installed to HDD. PublicIP, Linux wireless AP, runs from CD or HDD and config can be on local floppy and some items retrieved from the PublicIP website account. M0n0wall is a *BSD that runs from floppy or CF card. I just bashed out the details that I knew off the top of my head. You have to choose something that suits your comfort level. Any distro installed to HDD and exposed to the Internet needs to have a strong password. Block ssh to that box if you only want to change config while local to the box. Don't allow root to ssh, so you must ssh as a user and then su to root (two passwords req'd.). >-----Original Message----- >From: Behalf Of Leo Mauler >Sent: Wednesday, March 01, 2006 6:17 AM > >I was going over some of my old links (in backup CDs) and >found this interesting link to creating 1.680MB floppy disks >for use in floppy-based routers and >gateways: > >http://www.trevormarshall.com/byte_articles/byte19.htm > >This made me think about the whole concept of the PC-based >router/bridge.
