    Many folks have dismissed the concerns about Quova with comments along the lines of "Its just some paranoid sysadmins getting in a knot..." but it isnt paranoia. The usual precursor to an attack on any system is a ping sweep or portscan of your subnet looking for places there might be sploits, therefore its usual for these probes to set off alarms and usual for sysadmins to block them and bitch about them whenever they catch 'em.

    I'm not paranoid but I know that by the time a vulnerability is analysed and patched its usually been in the hands of a couple of script kiddies for a while so as well as keeping up to date with my patches I make damn sure that my network gives out as little info as possible - I may have patched my bind but it is still configured not to tell anyone its version, just in case. If somebody is walking down the street jiggling doorknobs to see if they are unlocked, peering over every garden fence and through any windows they can reach how long do you let them do it before calling the cops? So what do you do if there aint no cops? At the very least if you lived on that street you'd want a decent door lock, heavy curtains and you'd warn your neighbors when you saw a total stranger wandering down the road like that. In some parts of town those neighbors might well grab that stranger and try to convince him not to come back...

    BTW: I used to do Internet security consulting and computer forensics work, as well as sysadmin. Hopefully that means I know what I'm talking about.

    I've dealt with some of this before. I used to run a web hosting company's network. As a result of us hosting 100s of websites (we were small - I hate to see what the big guys deal with), we would daily get pings, traceroutes, port scans, attempted attacks, DOS attacks, VRFY/EXPNs, telnets, etc. Now, note that we only provided four services: WWW, FrontPage, FTP, and mail.

    If I even looked at all the logs for these "attacks", I would not be doing my job! I can hear it now, "He wasn't doing his job; he wasn't being alert about his systems." No, I disagree. I would get litterally hundreds of these "attacks" daily, and only a couple DOS attacks a month would be "serious" enough to disrupt things (and very mildly, I'll add). Yes, I noticed things that affected our customers. But, I didn't care about the rest of the $#@^! After all, if they got in, the logs would no longer exist. If they didn't, it is kind of pointless to look at logs for attacks that failed.

    I have to wonder what the people complaining about this do for a living. Obviously, they can't be complaining about a ping scan of a significant network, for they wouldn't have time to do that!

    As for the "ping is dangerous" theory, yes it is used sometimes by crackers. But, I bet that I could send your system an IP fragment and determine if it existed or not. I could even traceroute with it. Chances are, even if your system is behind a packet filter (vs. a real firewall), I would *STILL* be able to map your topography! It wouldn't show up on your filters, either. Do we really believe that our network design is so unusual and important that we need to protect it using "closed source" methods?

    Personally, I don't care if you look at my network. $#@^ with it, however, by causing DOS or breaking in, and you can bet that I'll call the FBI. Before then, though, because of the state of the Internet, I'm going to ignore you. I have no time to investigate every hacker coming through a chain of 10 trojaned Windoze boxes.
  • "Not setting off alarms" in this case means hacking through firewalls and scanning the machines within. They explicitly stated this. THAT is a gross violation of privacy, and possibly even illegal. A firewall should be just as much a sign that 'you are not welcome' as a banner statement on your login, and just as defensible (if not moreso, as it's a physical deterrent rather than just a statement) in court.

    Unless they're actually intruding, i.e. busting through firewalls or cracking in some way, it seems that this falls well within "fair use" of TCP/IP. When I was larval, I would scan any network I could find just to see how it was put together.

    If you don't want companies like this to see it, lock it down. It's not hard.

  • There are some non-secretive companies doing the same thing. Netcraft and Google come to mind. What's the big deal? Remember, all this data was explicitly made public by the respective owners--there is no privacy issue here.

  • True points, but there's one difference. You're talking about, most likely, pings of specific hosts, or VRFYs of specific e-mail addresses. No, those aren't enough to raise flags. But Quova is running scans of entire networks. Repeated pings through your entire address space, or repeated VRFYs scanning all possible mail addresses, are just a little more alarming than individual ones. And the fact that they want to do their scans without alerting me to the fact that they're scanning is even more alarming. That they want to scan is bad enough, but why do they want me not knowing they're scanning?

  • "but records with the Patent and Trademark Office suggest it has something to do with selling "psychographic" information, i.e., matching advertisments to particular lifestyles and beliefs." - Okay, first thing that rises to mind - how in the world can you get to know what lifestyle an certain IP or host has got, and what belief? This more looks like a group of grown up script kiddies really - "wh0a, w3 gotta scan the whole internet and find as many exploits as possible". Anyone who scans subnets/whole nets with pings for no official and very good reason should be shot really. There's no use for this but annoying ISPs and sysadmins world over.

    I consider pinging my system to be the electronic equivalent of jiggling my front doorknob to see if the door will open:

    I don't really think that those two are comperable. Ping tells you almost nothing. It gives no information about level of security (except "not blocking ping packets"), and there is no implication that someone would "come in" if the door was unlocked. Ping checks if something exists or is alive; it's information that anyone could get by a lot of methods, and this is probably the most "polite" one. It isn't someone jiggling a door, by telnetting into another port and playing patty-cake with your daemons; it's someone looking at the sign on the door that says "The doctor is not dead".

    No harm, no foul.

  • But after six months of constant probing, Quova says it's received only 100 complaints. A 1998 Internet mapping project by Bell Labs researcher Bill Cheswick drew 30 complaints after six months of scanning.

    Yes, but it's possible many others didn't detect it and would have complained if they knew about it. Look at the last quote:

    "...To that end, the company is working to refine its technique, so as to fly stealthily beneath the radar of firewalls and intrusion detection systems. "It's a goal we have," says Muniz. "Someday I'd like to get the system to the point where we don't set off anybody's alarms."

    They don't care about the people or their complaints; they just care about getting caught.

    Babykong dun said:

    It is perfectly legal to go through a neighborhood and knock on doors to see who answers. In fact, it's called market research. Most state laws consider this a right of easement

    Actually, this can vary from not only state to state but from county to county and even city to city or township to township.

    Most notably, here in Kentucky if anyone goes knocking on all the doors in an area where it is marked "POSTED NO TRESSPASSING" (yes, there is actually a legal status to a "posted" No Tresspassing sign--you actually register it with the county courthouse) or in areas with "No Soliciting" ordinances, they can quickly find themselves taken to the county jail and charged with tresspassing. Yes, this even applies to Girl Scouts/Girl Guides, Jehovah's Witnesses, those annoying folks selling magazines, etc. Literally the ONLY things that "No Soliciting" ordinances don't cover are census workers and police with warrants; I'm not entirely sure that even census workers are allowed on posted property (I think they may have to actually get police escort or a warrant to perform census to legally go on the land without permission of the landowner).

    For the record, yes, I not only am part owner of property that is "posted" but live in an apartment complex with a "No Soliciting" rule. Yes, I do have people removed who are tresspassing and/or soliciting without my permission (as it is, in my area the Girl Scouts generally don't go door-to-door both out of safety concerns and because a lot of apartments and even entire communities have "No Soliciting" ordinances--they sell outside grocery stores and to family members and friends of family). :)=

  • The funniest thing is that I interviewed with them prior to posting to that site (in fact, I suggested that site!) and warned them that what they were proposing could be misinterpreted as an attack. I pointed them to the then-recently completed Internet Security Scan.

    I don't think they believed me.

    I passed on the job for other reasons, and unless they've gone off into a wildly different direction in the past 6 months or so they really do need a lot of data and they really are attempting to extract innoculuous information. But I can't talk about it, sorry!
  • Just a note,

    I've been in contact with Digiweb (an Interliant company).

    Just FYI, the scans are not coming from them. Their website is simply hosted there. But in response and to avoid security "problems", the site has been taken down. Gotta love security precautions

    So for now, at least they can't spread anymore of their corporate mumbo jumbo

    Also it appears the DNS is in the process of changing. We're seeing odd IP changes here (I'm right off the Digiweb network) so it appears they are moving the site.

    Any info on the source of the IP scans would be appreciated.

  • ... about how long it'll take until 205.177.226.233 becomes a DeCSS mirror? Or worse: until sysadmins will actually have a very good reason for getting their panties in a knot about packets from 205.177.226.233 . Oh gawd, and to make matters even worse, it's Friday!
  • I like you're analogy.

    But it leaves me wondering about those roads with no gate, but the sign, "Private Road - no tresspassing" on them. They don't receive town snowplowing, and are usually (though not always) unpaved.

    What's the net analog to Private Roads?

    This discussion makes me wonder if their "No Tresspassing" is as toothy as a pre-UCITA shrink-wrap license.
  • they're pissing off sysadmins to draw sysadmins (looking for a place to complain) to their webstie which will be a sysadmin portal....
  • They're pinging everything to see what's out there? Well. I think we should show them. Make it easier for them and all that.

    Everybody ping them back and run traceroutes to their systems.

    Go on, ping www.quova.com today. :)

  • Unless they're actually intruding, i.e. busting through firewalls or cracking in some way, it seems that this falls well within "fair use" of TCP/IP

    sure, no problem. everyone on /. please ping/traceroute this company constantly, it's fair use. i wonder how many complaints they'll have after a six month long /.'ing.

    The traceroute information is a useful tool in narrowing the location. Plot a traceroute on a map, and you'll intuitively start guessing what part of the country it's going to end up in. At some point it resolves to your local ISP, which gives them your county or city.

    Where ping fits in, I dunno, other than perhaps it provides the IP addresses for traceroute to digest. And there is useful information in being able to ping a machine and identify that it's still online in the dead of night: that implies it's a full-time connection, which means you're a cut above the average dial-up user.


    Here's how ping fits in

    A traceroute is a number of pings. Here is how it works:

    Each ICMP packet is sent out with a "Time-To-Live" (TTL), as the packet passes each router the TTL is reduced by one, when the TTL reaches zero the ICMP-echo packet is returned to the source IP with TTL expired.

    When doing a traceroute the source IP sends out a "ping" (ICMP-echo) packet with a TTL of 1, the TTL expires at the first hop and you get the reply "Reply from router.at.hop.1: TTL expired" then it sends out a ping to the same address with a TTL of 2, it passes the first host (usually router.at.hop.1) and gets to "router.at.hop.2" where, once again the TTL expires and the echo gets sent back with "Reply from router.at.hop.2: TTL expired" this goes on until the destination IP is reached or some other thing happens ("Network Unreachable" for instance)

    That is how traceroute works. It is just a load of pings.

    Aside: TTL wasn't designed for traceroute - it's main use is to prevent packets entering cyclic routes and taking up enormous bandwidths ad infinitum.

    Hope this is informative to you.
  • It is perfectly legal to go through a neighborhood and knock on doors to see who answers. In fact, it's called market research. Most state laws consider this a right of easement.

    As long as the ICMP packets are normal and not maliciously malformed so as to either do a DOS or get more information than ICMP was designed to give. Then I don't have a problem with it.

    That is why I have a network inside my firewall which you can't ping, and a network outside my firewall, provided by my company for public access, which you can ping.

    Hosts on the Internet are there for public access, the internet is a public place. Use of these tools is designed to improove that access which is apparently what this company is trying to do.

    ON THE OTHER HAND.

    Might be fun to play with a gentle (not a DOS, throttle it back a little) Nmap scan on THEIR network. Since they are in stealth mode, they can't complain very loud :)

  • I'm not sure it even gives you that information.
    Well, if you get a ping back, you know they're "not blocking ping packets" ; )
    But your point is definately valid; from the standpoint of ping (or traceroute), there's no difference between a system that is blocking certain packets and one that has bought the farm. You're probably right that that information can be extracted somehow, but it would take more work. And it reinforces the idea that the threat posed by these guys pinging and tracerouting random systems poses roughly as much danger as a wrong number on the telephone ("Some stranger knows my phone number works! Run!").

  • Your tragic misspelling of "please" has tainted the Matrix. Your question is therefore REJECTED!
  • Very few script kiddies are stupid enough to run port scans off their own machines (I'm going out on a limb here). I've found that most scans originate from compromised hosts. By calling/emailing the owners I let them know their site has been hacked. About a quarter of replies thank me for discovering a script kiddie.

  • People are blowing this way out of proportion. So they are ping scaning the internet. Who cares. They are not hurting anyone by finding out if a machine is up or not.
    The fears of malicious intent are also blown way out of proportion. People have said if they dont have any ill-intent why are they doing it so secretely. Read these post, its fairly obviously, because you get lots of idiots that get all paranoid about people portscanning them. Doing it secretely possibly reduces the amount of people who go crazy because they think they are under attack.
    Thier are alot of legitamate uses for this data. For one, internet topology maps. There are multiple internet mapping websites that scan the internet and creat a graphs and maps of the data they find. Statistics are vary valuable, and it helps governments and companies to make descisions based on internet usage in certain areas. Two, like mentioned before, they could possible using the information to find geographic locations with high latency. With this information companies can best locate servers to provide the fastest speed to their customers.
    Basically everyone needs to loosen up. IF they were running a vunerability scan on your network, that is one thing to get upset about. That is still perfectly legal, and they could do that if they wish. But they are not, they are traceroute and portscanning.

    They won't be scanning EVERYONE

    i just added their IP address range as a DROP rule to my company's ipchains configuration. we can no longer view their web page, and they can no longer ping or traceroute us. we will appear dead to them.

    i encourage the rest of you to do the same until we know what happens to this information. remember, the human genome is patented (by the company across the street from me, celera!) so i'm pretty sure the "web genome" or "web topology" could be patented too... think about it...

    You know, I really wish I had a link for this, it's a great story, and I know I'll screw it up.

    Something like a year or two ago something really similar was done. A group of people had gotten together and decided to survey the 'net on security. They did this, as I recall, by doing your standard ping/traceroute/portscan for just about anything. IIRC, they also 'tested' to see if the then 10 most common exploits were vulnerable.

    Two interesting things came about from this. One, of course, was the results. Only something in the vicinity of 12% of their search space was 'secure' by their tests. .com's and .gov's were the most vulnerable, as well.

    The second was the people they pissed off. Scr1pt K1dd13s DoS'd once or twice. Some network admins sent and e-mail asking why portscans had come from that domain. Others threatened legal action and had 'sent logs to the FBI.' And then there was this one guy... I can't even do him justice, but in .7 seconds he'd fscked their systems like you wouldn't believe.

    Anyway, it wouldn't surprise me to find that something similar was happening again. I've got no problems with my box being probed. Honestly, if you freak at a portscan, you're a liittle paranoid.

    Oh, and hey... some karma whore go dig that link up. May very well have been from this site ;)

    I find it disturbing that this is one of Quova's goals, coupled with the fact that they won't reveal what their service is. Does he mean that his goal is to hit servers across the Internet without being detected?

    Scary.

    There is absoutely nothing wrong with that. Nothing creepy about it at all, IMHO.

    It's a free country, internet, whatever. Of course people will find bigger and better ways to do "market research". It's all part of the game. I'm a lot less worrysome about some advert company spying on me than the FBI, Uncle Sam, etc. Companies are more concerned with making money from you than censoring and opressing you...

    ...unless of course they can make money by doing that;)

  • ... we specifically block their IP in our firewalls. I think that the beef that most people would have with this company is that it is secretive, they don't tell us what they're doing with this info. On the other hand, Google's and Netcraft's motives are entirely clear: search engine and OS surveys, so nobody objects.

    Btw, does anybody know Quova's IP address range, so that we know what to block?

    If this bothers you, there is a way to protect yourself from such things in Linux. At a command line log in as root and tyoe the following line;

    echo 1 > proc/sys/net/ipv4/icmp_echo_ignore_all

    Now add this line to your rc.local file, so when you have ever have to reboot your system, you won't have to remember to do it. This line make it so your system will not respond to ICMP packets, meaning ping and traceroute. I don't know if Windows has a similar feature or not.

    As a former census worker:

    Census workers, by federal law, are given the right to canvas all residences, including those that are officially "posted". Their Census ID badge serves as their warrant for that purpose. This law is authorized by the Constitution, which provides that a census shall be taken of all residences every 10 years. It's one of the few laws passed over the past 200 years which does abide by the Constitution :-}.

    However, you are correct that there are some residences where census workers will not go without a police escort. Specifically, those where the resident's reaction to the census worker was to poke the barrel of a gun out the door! Our instructions when such things happened was to get the bleep out of there, and turn it over to a supervisor, who would probably give it to a cop who would go out there and give the guy a nice little talking-to about the inadvisability of brandishing guns at census workers. If we could talk to a neighbor and get the information, great. If not, then the next step was the supervisor and a cop going to the guy's house to politely question him about who was living in his house on Census day.

    As a matter of fact, it was from this site. The Internet Auditing Project [securityfocus.com], posted here [slashdot.org] on August 14, 1999. It's a really good article, certainly worth a read.

    I can't believe the number of posters who are worrying that this company is somehow scanning their networks or invading their privacy. Numerous posts refer to port scanning, despite the fact that the article neither states nor implies that they are doing any such thing. Numerous comparisons are made to walking down a street trying all the doorknobs looking for unlocked doors. This is a completely unfounded comparison.

    Yes, running a portscan of a host is a lot like checking to see if any windows or doors are unlocked. However, pinging hosts is not like trying doors. It's not even like knocking on doors. It like driving down a street and taking note of which lots have houses on them. Having somebody ping your host has zero negative impact on your performance, and the only security related information it reveals is whether or not the address is in use at all.

    Traceroute is the same way. It's not revealing anything personal, private, or security related to the person running traceroute. It's most akin to somebody driving around your neighborhood building a map of the streets. Thank god the paranoids around here aren't making up the laws in meat space. They would make it illegal to drive into a neighborhood and even look at the houses without being escorted by a resident. After all, if a person doesn't live in your neighborhood, they don't have any business there, right? And everyone knows that criminals drive around looking at the houses trying to figure out which one to rob, right? So lets make it illegal to drive thru any neighborhood without the permission of the residents. Never mind that on the Internet, there is no zoning and there is no way to distinguish "residential" addresses from "business" addresses.

    And I could care less if some of you get paged when these folks ping your network. That's your problem, that you let something this innocuous interrupt your life. You could have your pager go off every time time_t takes on a prime value, also. That doesn't make prime numbers evil.

    I have not authorized anybody to scan my computer.

    That's okay, because nobody asked for your permission anyway. I can understand why one would be nervous about getting scanned, but if your system is secure [openbsd.org], you have nothing to fear.

    Anyhow, there's a legend about Werner Von Braun at NASA that goes like this: In the early days of the space program, Von Braun was in charge of the facilities at the Redstone Arsenal in Huntsville Alabama. They needed to build a large neutral bouyance tank to simulate weightlessness, so they just built one. Later when government officials were visiting, they saw the large tank and were upset that Von Braun never went through any red tape in Washington to get an official budget to build the tank.

    <feds>: We never gave you permission to build the neutral buoancy tank!
    <VonBraun>: That's OK, I never asked ;)

    THIS IS WHAT THEY ARE DOING:

    Based on the senior engineer job posting that someone else mentioned, some of the discussion here and a bit of creative thinking, here's what I believe they are doing:

    They are developing localized web advertising. They are working to resolve IP addresses to physical locations: cities and neighbourhoods.

    Once they've built a map that translates virtual space to realspace, they can sell advertising services that are far more effective.

    Your local retailers, for instance, can advertise to you. Just like they do in your newspaper, only in banner format.

    Further, they will be able to target your demographic specifically. Some neighbourhoods are richer than others. No point in selling you McDonald's advertising if you're of La Maison Rouge quality.

    The traceroute information is a useful tool in narrowing the location. Plot a traceroute on a map, and you'll intuitively start guessing what part of the country it's going to end up in. At some point it resolves to your local ISP, which gives them your county or city.

    Where ping fits in, I dunno, other than perhaps it provides the IP addresses for traceroute to digest. And there is useful information in being able to ping a machine and identify that it's still online in the dead of night: that implies it's a full-time connection, which means you're a cut above the average dial-up user.

    What we'd all better hope is that there's no way for them to patent the map. Doing so would be the equivalent of having the patent for the map of all the roads in the country.

    ooooh... and tie the IP addresses to DoubleClick's personal database, and they'll be able to do targeted snailmail advertising. If you've got a fulltime connect, your IP is as good as your street address. If you're dialup, the number is shared with others in your locale... but all of you are a distinctly different demographic than the population that doesn't access the Internet.

    And, tied to the DC's database, they can really get into the psychographic stuff. "This IP reads a lot of pr0n; this one is a snowboarding junkie; here's one that's been researching home decorating..."

    I'm more and more positive that this is their goal!

    This is a very interesting comparison. Remember that Cheswick *invented* the firewall! His mapping project was meant to get some understanding of the topology of the modern Internet. He discovered that you can supposedly get from any one site to any other in something like 10 clicks.

    There has been a lot of traffic on the SecurityFocus mailing lists over the last couple of weeks about Quova. Many people are upset with them because they see port scans and ping scans as the equivalent of casing a building for break in. There is nothing strictly illegal about rattling doorknobs, but you can imagine that it will not win you any favor with your neighbors.

    By the way, I heard Cheswick speak a couple of years ago at a SANS conference. He was one of the most widely knowledgable and overall brilliant speakers I have ever heard. He's a cool guy and definitely *not* in the same league as Quova.

    Heh, let me tell you my story about a portscan.

    I do a lot of mud hacking, I love muds. A friend of mines mud runs at xyz.com

    It is a mud hosting service so as you can guess they have multiple muds running on their site. I downloaded nmap and was learning to use it. So I scanned 1-1024 ports first I think that is the default not sure.

    Anyways I did it again and let it go 1-10000 to find most any mud on their, I can give a crap about any of their other services I think using exploits on peoples systems is just so lame but I digress from my story :).

    He had port sentry setup and it detected nmap as a DoS attack from the type of packets it was using. Ugh I cant remember the word for them, Im losing it. Anyways Port sentry shut down their ROUTER!!!!

    They emailed my ISP and my ISP shut down my account with them! I was livid.

    No You dont have business port scanning but I mean come on!!SOOOOO

    I log onto the net with another account and I send him my phone # and tell him to call me.

    I have a little chat with him established my intentions and hes all talking if it happens again they are pressing charges because they have it set up so that it detects this as a DoS and just freaking locks downt he router and ALL their systems hardcore. I felt this was a bit paranoid but I was not certain of my rights and if I indeed was violating any laws, he believed I was. He was some major security buff who just happened to maintain this mud server.

    Ahhhh. I just found the entire thing a bit hmmmn.. interesting. So he calls my ISP up says the issue is resolved and my account is restored.

    Hmmmn?

  • ...not a good thing I know, but anyway I came to the concusion that we should never have told the idiots about the internet. Imagine if it was just geeks:
    • All pr0n would be free ;-)
    • Things like this would not happen
    • Spam and Trolls wouldn't exist - that means you beerboy and penisbird
    • The goverment wouldn't know how to destroy our privacy with it
    • More slashdot posts would be worth the bandwith they consume.
    • Microshit would be unable to fsck-up our open protocolls

    Thus it is plain, the dumbest thing we ever did was to tell the idiots about the internet !!!

  • ...someone just typed by accident:

    root@quova:~$ ping *.*.*.*
    root@quova:~$ traceroute *.*.*.*

    Honestly, if you freak at a portscan, you're a liittle paranoid.



    Then the job of a systems administrator is to be paranoid. If my systems are being portscanned, I *better* investigate it and figure out what is going on.



    Onto the bigger issue, I can see both sides. On one hand, I consider "ping" to be a _public_ network service. That is, if I send a ping packet to your machine, and it responds, it isn't intrusion (or "theft of CPU time") because you provide ICMP responses to the world as a regular service.


    On the other hand, if someone is pinging my network in order to scan it, I am going to get miffed. Nothing I can do about it.

    Yeah, maybe that's where this psycho-profile is coming from. They determine what software your box is running and then assess your personality and buying habits from that.

    For instance...

    Running Windows 95/98/NT - Will buy anything, start spamming immeadiately.
    Running BeOS - Will buy anything, so long as it is obscure or different. Try to sell them some gas-powered boots.
    Running Linux - Likes bandwagons. Try to off-load britney spears and pokemon.
    Running Commercial Unix - Resists bandwagons. Try to sell them some more 5,000 dollar operating systems.
    Running Windows 3.11 - Too stupid and/or poor. Don't bother.

    Common sense says "my network is my property, and mine alone to allow visitors".

    However, the IP address space is a public resource, documented and available to any who are willing to participate. You can look up any address block and find out who owns it if you want (like a Registry of Deeds here in most US states). And in order to get a block, you have to agree to the "rules".

    The question I'd ask here is "where is the boundary between public and private property?" Obviously, if a system is accessible over the Internet and a service is available, then that service, at least, probably meets the requirements of "public", even if the owner doesn't realize that the service is accessible. Using that service may be public, even though it's not polite.

    I'd say if it's behind a firewall that blocks the pings, or not accessible through a NAT export, then it's private. Kind of like the difference between a gated community and a regular old subdivision, to use an imperfect analogy. I can drive into a subdivision, map and photograph every street and house I see, and then use the information for whatever legal purpose I want (I could legally sell it to people wanting, for instance, to publish guides to preferred neighborhoods). I'm free to look at the houses so long as I don't actually trespass on the private property that they rest on.

    If I want to map and document a gated gommunity, though, the street is private and blocked off, with restricted access. I need the permission of whoever runs the gatehouse to go inside and map the streets and houses within. If I can see all the houses without having to go through the gatehouse I can still take my photographs, though.

    And there's the conundrum. If I block all inbound access to my network (except for exported hosts), then the scans will be stopped at my gatehouse (firewall), and only the things I have chosen to make visible will be mapped. Those systems are public, though my network is private.

    Where this company is being unethical is in trying to do this activity as stealthily as possible. If a surveyor wants to try and map my neighborhood, fine. Let them show me their credentials and announce their presence. If I see someone skulking around in the middle of the night in a car with the lights dimmed, who pauses in front of each house for a while, I just may think they're up to no good. And someone else may think that and either call the cops (the offending visitor's ISP) or just shoot 'em.

    If I don't want to be mapped (and I, for one, don't), I'll erect my own gate and cordon off my address space that way. If someone sneaks in anyway then I may shoot the varmint myself.
