There's and old thread closed.

Today - - [23/Jan/2007:14:54:56 -0800] "GET /robots.txt HTTP/1.1" 403 - "-" "O#*$!earch/1.x (www.o#*$!earch.com)"

SMBot?! ([webmasterworld.com ])

Advertised website openisearch.com is hosted by "specificmedia".

O#*$!earch/1.x (www.o#*$!earch.com)

Are the odd characters part of the UA or yet another bug in the software?

For people using PHP's get_browser() function, adding this to their browscap.ini file without quotation marks will cause errors. That would make this a malicious bot. Would Amazon do something like that?

Am I missing anything Don? Thanks.

Gary, it's censorship by WebmasterWorld.

o#*$!earch is openisearch, but there is a "bad" word between O and E. I think Specificmedia knows about WebmasterWorld's censorship.

Amazon is not running bots from! They sell computer power and bandwidth to anyone. It's like a temporary virtual server. See here: [webmasterworld.com...]

Gary and trasher,
I read a recent announcement (believe in the IAR [renamed] relases) were Amazon, eBay and another were partnering in a venture that was SE related.

the bot name is " open I search" all one name.

I believe the forum censor is screening the alternative word for phallus.

I always thought the dirty words filter used asterisks. Oh well.

just a heads up. - - [26/Jan/2007:20:37:04 -0800] "GET /robots.txt HTTP/1.0" 403 - "-" "complex_network_group/Nutch-0.9-dev (discovering the structure of the world-wide-web; [cantor.ee.ucla.edu...] nimakhaj@gmail.com)"

Iím pretty sure this is either the little brother of SMBot or itís replacement. Can anyone else confirm that this is run by Specific Media? Sure smells like it. Since we discussed it and I started banning it, SMBot completely quit hitting my sites and OpenISearch picked up where it left off, slamming my sites, even worse than SMBot.

Here are some interesting similarities with SMBot:

1) OpenISearch has the same format for the User-Agent:
- OpenISearch User-Agent: OpenISearch/1.x (www.openisearch.com)"
- SMBot User-Agent: "SMBot/1.1 (www.specificmedia.com)"
2) The web sites are a very similar design style.
3) OpenISearch and SMBot both come from the same IP block (216.182.236.*, 216.182.237.*, 216.182.238.*) and server at Amazon Web Services (compute.amazonaws.com).
4) Both domains are registered to "Domains by Proxy".

Went to teh site listed in the User-Agent, www.OpenISearch.com, and it's a front. Claims to be "The Ultimate Search Engine", that will have "more results than all other search engines combined". They're planning to overtake Google, Yahoo, and MSN? Have fun with that.

None of the links on the page are even working...it claims to be "Coming Soon". Hmmm...

Anyone else have info on OpenISearch/SMBot? Please contribute.

I went through my logs again and found more IP blocks that these bots have in common. Here's my complete list:



 3:11 pm on Feb 7, 2007 (gmt 0)

RewriteCond %{REMOTE_ADDR} ^216\.182\.2(2[4-9]¦3[0-9])\. [OR]

Thanks for the info wilderness. I'm guessing you've had it hit a few of your sites?

I'm guessing you've had it hit a few of your sites?

In early December I added the range as a result of threads referenced in this thread.
OpenI has been relentless at eating 403's of the IP range denial.
OpenI also catches a SetEnvIf for "Open".

In addition I'm getting some slight traffic from the following (course the below catches three rules; one for the IP range (same Class C as OpenI) and the other for Nutch), as well as "crawl".)

216.182.236.zz - - [05/Feb/2007:18:47:20 -0800] "GET /robots.txt HTTP/1.0" 403 - "-" "complex_network_group/Nutch-0.9-dev (discovering the structure of the world-wide-web; [cantor.ee.ucla.edu...] nimakhaj@gmail.com)"

As a result of the four rules implemented in SetEnvIf (my SetEnvIf and deny from's are not configured to allow the reading of robots.txt, whewereas my Rewrites for specific IP ranges are allowed access to robots.txt), neither is able to read robots.txt and is stuck in a 403 loop.


 10:43 am on Feb 11, 2007 (gmt 0)

Thanks Wilderness. So, updated range is: 216.182.224.* - 216.182.239.* (for newbies not familiar with Regex)
