I've got a problems because of 360Spider: this bot makes too many requests per second to my VPS and slows it down (the CPU-usage becomes 10-70%, but usually i have 1-2%). I looked into httpd logs and saw there such lines:
182.118.25.209 - - [06/Sep/2012:19:39:08 +0300] "GET /slovar/znachenie-slova/42957-polovity.html HTTP/1.1" 200 96809 "http://www.hrinchenko.com/slovar/znachenie-slova/42957-polovity.html" "Mozilla/5.0 (Windows; U; Windows NT 5.1; zh-CN; rv:1.8.0.11) Gecko/20070312 Firefox/1.5.0.11; 360Spider
182.118.25.208 - - [06/Sep/2012:19:39:08 +0300] "GET /slovar/znachenie-slova/52614-rospryskaty.html HTTP/1.1" 200 100239 "http://www.hrinchenko.com/slovar/znachenie-slova/52614-rospryskaty.html" "Mozilla/5.0 (Windows; U; Windows NT 5.1; zh-CN; rv:1.8.0.11) Gecko/20070312 Firefox/1.5.0.11; 360Spider
etc.
How can I block this spider completely via robots.txt? Now my robots.txt looks like this:
User-agent: *
Disallow: /cgi-bin/
Disallow: /tmp/
User-agent: YoudaoBot
Disallow: /
User-agent: sogou spider
Disallow: /
I've added lines:
User-agent: 360Spider
Disallow: /
but that does not seem to work. How to block this angry bot?
If you offer to block it via .htaccess, so mind that it looks now like this:
# Turn on URL rewriting
RewriteEngine On
# Installation directory
RewriteBase /
SetEnvIfNoCase Referer ^360Spider$ block_them
Deny from env=block_them
# Protect hidden files from being viewed
<Files .*>
Order Deny,Allow
Deny From All
</Files>
# Protect application and system files from being viewed
RewriteRule ^(?:application|modules|system)\b.* index.php/$0 [L]
# Allow any files or directories that exist to be displayed directly
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# Rewrite all other URLs to index.php/URL
RewriteRule .* index.php/$0 [PT]
And, in spite of presence of
SetEnvIfNoCase Referer ^360Spider$ block_them
Deny from env=block_them
this bot still tries to kill my VPS and is logged in access logs.
In your .htaccess file simply add the following :
RewriteCond %{REMOTE_ADDR} ^(182\.118\.2)
RewriteRule ^.*$ http://182.118.25.209/take_a_hike_moron [R=301,L]
This will catch ALL the bots being launched from the 182.118.2xx.xxx range and send them back to themself...
The crappy 360 bot is being fired from servers in China... so as long as you don't mind saying bye bye to crappy Chinese traffic from that IP range, this will guaranteed make those puppies disappear from reaching any files on your web site.
The following two lines in your .htaccess file will also pick it off simply by it being stupid enough to proudly put 360spider in its user agent string. This could be handy for when they use other IP ranges then the 182.118.2xx.xxx
RewriteCond %{HTTP_USER_AGENT} .*(360Spider) [NC]
RewriteRule ^.*$ http://182.118.25.209/take_a_hike_moron [R=301,L]
And yes... I hate them too !
Your robots.txt seems right. Some bots just ignore it (malicious bots crawl from any IP address from any botnet of hundreds to millions of infected devices from all around the globe), in this case you can limit the number of requests per second using mod_security module for apache 2.X
Config example here: http://blog.cherouvim.com/simple-dos-protection-with-mod_security/
[EDIT] On linux, iptables also allows restricting tcp:port connections per (x) second(s) per ip, providing conntrack capabilities are enabled on your kernel. See: https://serverfault.com/questions/378357/iptables-dos-limit-for-all-ports
You can put following rules into your .htaccess file
RewriteEngine On
RewriteBase /
SetEnvIfNoCase Referer 360Spider$ block_them
Deny from env=block_them
Note: Apache module mod_setenvif should be enabled in your server configuration
The person running the crawler might be ignoring robots.txt. You could block them via IP
order deny, allow
deny from 216.86.192.196
in .htaccess
SetEnvIfNoCase User-agent 360Spider blocked
I have lines in my .htaccess file like this to block bad bots:
RewriteEngine On
RewriteCond %{ENV:bad} 1
RewriteCond %{REQUEST_URI} !/forbidden.php
RewriteRule (.*) - [R=402,L]
SetEnvIf Remote_Addr "^38\.99\." bad=1
SetEnvIf Remote_Addr "^210\.195\.45\." bad=1
SetEnvIf Remote_Addr "^207\.189\." bad=1
SetEnvIf Remote_Addr "^69\.84\.207\." bad=1
# ...
SetEnvIf Remote_Addr "^221\.204\." bad=1
SetEnvIf User-agent "360Spider" bad=1
It will send the status code 402 Payment Required to all blacklisted IPs / user-agents.
You can put anything that you want displayed to the bot in forbidden.php.
It's quite effective.
I just had to block 360Spider. Solved with StreamCatcher on IIS (IIS7), which fortunately was already installed so only a small configuration change was needed. Details at http://needs-be.blogspot.com/2013/02/how-to-block-spider360.html
I use the following, and it helps alot! Check the HTTP_USER_AGENT for bad bots
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_URI} !^/robots\.txt$
RewriteCond %{REQUEST_URI} !^/error\.html$
RewriteCond %{HTTP_USER_AGENT} EasouSpider [NC,OR]
RewriteCond %{HTTP_USER_AGENT} YisouSpider [NC,OR]
RewriteCond %{HTTP_USER_AGENT} Sogou\ web\ spider [NC]
RewriteCond %{HTTP_USER_AGENT} 360Spider [NC,OR]
RewriteRule ^.*$ - [F,L]
</IfModule>
<Location />
<IfModule mod_setenvif.c>
SetEnvIfNoCase User-Agent "EasouSpider" bad_bot
SetEnvIfNoCase User-Agent "YisouSpider" bad_bot
SetEnvIfNoCase User-Agent "LinksCrawler" bad_bot
Order Allow,Deny
Allow from All
Deny from env=bad_bot
</IfModule>

Let me start by saying I am new to creating an htaccess file. I want to deny certain IPs from access to our site. I created this and I am looking for validation that this is correct. I know that there is no advanced redirect page within this as I am not sure how to accomplish that yet. I am more concerned that this snippet would work to block IPs. Thanks in advance for any and all help.
#.htaccess
DirectoryIndex index.htm
#deny list
order allow,deny
allow from all
deny from xxx.xxx.xxx.xxx
deny from yyy.yyy.yyy.yyy
Looks good to me, assuming you're on Apache 2.2 To block individual visitors, you can use the following directives:
Order Allow,Deny
Allow from all
Deny from 123.123.123.123
Instead of blocking visitors, you can redirect them to another location. Here's how to do it using Apache's mod_rewrite:
#<IfModule mod_rewrite.c>
RewriteCond %{REMOTE_ADDR} ^123\.123\.123\.123$
RewriteRule .* https://www.google.com [R=301,L]
#</IfModule>
See also: https://htaccessbook.com/block-ip-address/
Alternatively, try this to block a range if IPS (here 10.0.8.0-10.0.8.21:
RewriteEngine On
RewriteCond %{REMOTE_ADDR} ^10\.0\.8\.(2[01]|[0-9][0-9]|[0-9])
#or RewriteCond %{HTTP_HOST} 12\.34\.56\.789
RewriteRule .* https://www.google.com [L,R=301]
If you are on Apache 2.4 this link from the htaccess book shows the differences between 2.2 and 2.4: https://htaccessbook.com/access-control-apache-2-4/
I want to block out user agents and tell them that the file doesn't even exist (Status Code: 404)
My current htaccess (Status Code: 403):
RewriteEngine on
SetEnvIfNoCase User-Agent UpdaterV* updater
Order Deny,Allow
Deny from All
Allow from env=updater
How can I fix this?
You can use mod-rewrite to get 404 status code :
RewriteEngine on
#--if user agent is not UpdaterV--#
RewriteCond %{HTTP_USER_AGENT} !UpdaterV [NC]
#--404 the request--#
RewriteRule ^ - [R=404,L]
I'm trying to block Baiduspider via htaccess but it still gets through.
Here's the full useragent of the Baiduspider that doesn't respect the robots.txt and isn't turned away by htaccess:
Mozilla/5.0 (compatible; Baiduspider/2.0; +http://www.baidu.com/search/spider.html)
Here is what I have in robots.txt to try to block him (I know this one is most likely not the real Baiduspider and the impersonator won't respect robots.txt:
User-agent: Baiduspider
Disallow: /
Here is what I have in htaccess to deal with him. Is there something incorrect in this or would someone suggest a better alternative?
RewriteEngine On
RewriteCond %{HTTP_USER_AGENT} ^Baiduspider.* [NC]
RewriteRule .* - [F]
I also tried this in htaccess and it still didn't solve it:
SetEnvIfNoCase user-agent "^Baiduspider" bad_bot
<FilesMatch "(.*)">
Order Allow,Deny
Allow from all
Deny from env=bad_bot
</FilesMatch>
I have a large htaccess file for my site. One of the IPs I'm trying to block is 27.153.228.56
Despite my htaccess, I still see 27.153.228.56 showing up in my latest visitor logs.
Is there something wrong with my htaccess that's allowing this IP to access the site?
There are many more IPs blocked but this is an abbreviated version:
# Protect from spam bots
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_METHOD} POST
RewriteCond %{REQUEST_URI} .wp-comments-post\.php*
RewriteCond %{HTTP_REFERER} !.garagehangover.com* [OR]
RewriteCond %{HTTP_USER_AGENT} ^$
RewriteRule (.*) ^http://%{REMOTE_ADDR}/$ [R=301,L]
</IfModule>
# Begin IP blocking #
Order Allow,Deny
deny from 27.153.228.56
# End IP blocking #
#Begin Bad Bot Blocking
BrowserMatchNoCase yandex bad_bot
Deny from env=bad_bot
# End Bad Bot Blocking
Allow from all
Order Deny,Allow
And remove Allow from all
This will process all the deny rules, and if none match, allow the request.
Also, generally you would put these rules before the RewriteEngine on directive.
Looks ok to me. But you could try to block a range of IPs like this...
deny from 27.153.228.0/255.255.255.0
or this
deny from 27.153.0.0/255.255.0.0
Trying to block directory access from everyone except 1 IP address. This .htaccess code blocks access but it blocks access to everything including images, css, etc. What do I need to change?
RewriteCond %{REMOTE_ADDR} !^XX\.XXX\.XX\.XXX$
RewriteRule ^hidedirectory(.*)$ http://site.com/ [R,L]
Anyone accessing mysite.com/hidedirectory except me should redirect to mysite.com. Is there a better, more secure way to do this including something like an http response code?
Better way is to do this in your .conf file:
<Directory /hidedirectory>
options -Indexes
Order Deny,Allow
Deny from all
Allow from XX.XXX.XX.XXX
</Directory>
This will deny everythig like your rewrite rules.
But since you want to allow access to images/css etc...
RewriteCond %{REMOTE_ADDR} !^XX\.XXX\.XX\.XXX$
RewriteCond %{REQUEST_URI} !\.(?:jpe?g|png|gif|css)$ [NC]
RewriteRule ^hidedirectory(.*)$ http://site.com/ [R,L]
Add any other extensions into (?:jpe?g|png|gif|css) suffixed by a |(or).
