* Hi,
* Getting lots of bot traffic with Linux (at least that’s what i see in Google
Analytics),
* Can i just place user – agent Linux and it will block all User agents that have
Linux in it?
* Thank you
Mark

* You should be able to use **Enter User Agents:** field to enter your bot located
in **Blacklist Manager** tab in admin settings.
* Let me know if it works for you.
* Thank you

* Sorry, didn’t understand.
* what i meant is if i need to place for example “Linux x86_64” or i can just place“
Linux” to block all user agents that have Linux in the name.

* Hi,
* No, it doesnt work.
* i see this code in httaccess, i marked to block fake google bots – i see exactly
the same bots with Linux UA coming without being blocked. Can you please advise
how to fix it?
* This is the httaccess code i see:
RewriteEngine On
* RewriteCond %{HTTP_USER_AGENT} ^Linux\sx86_64 [NC]
RewriteRule ^(.*)$ – [F,L]

the feature that best suits your needs.
* **Completely Block Access To XMLRPC:
Disable Pingback Functionality From XMLRPC:
* The above features are located in **WP Security -> Firewall -> Basic Firewall

* I think the problem is in the way your plugin translates “Linux x86_64” which
i placed into this part of the code: ^Linux\sx86_64
something there not correct.
I tried with different plugin and this part was different. like this: Linuxx86_64
* can you please suggest a solution.
* Even better, is it possible to block by using exact match with multiple parameters
together – i mean in a same way as doing google search for exact sentence.
* Like blocking “X11; Linux x86_64”

* Hi [@mark8888](https://wordpress.org/support/users/mark8888/)
Do all of these
bots have a user agent string which **starts** with the word “Linux”? Could it
be that the user agent strings which contains “Linux” all start with something
different? Are you able to check what the exact user agent string is?
* I tried a few tests on my site by simply entering “Linux” in the blacklist “user
agents” section and I was able to block requests which had a user agent such
as this one:
Linux x86_64

* Hi,
* I think if you place just Linux it does work. But by doing so you are blocking
all Android users. I think the problem is with how Linux x86_64 entered into
the code – maybe the space there messes things up.
* The full string is usually: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36(
KHTML, like Gecko) Chrome/69.0.3497.100 Safari/537.36

* Actually the space should not affect the correct operation of the blocking rules.
For example, I also tried entering the following in the settings: Linux x86_64
* The above appears as follows in my .htacces file:
RewriteCond %{HTTP_USER_AGENT}
^Linux\sx86_64 [NC]
* The blocking still works as expected except this time blocking only occurs for
visitors with user agent string which **exactly** matches “linux x86_64” (note:
it is case insensitive).
* Have you asked your host support people to see if they can help?
Have you also
checked to see if some other .htaccess directives in your file might be conflicting
with these rules?

* Yes, i have the same code in httaccess.
* Please explain what you mean exact match. For example – this bot should be blocked“
Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/
69.0.3497.100 Safari/537.36” – but it’s not.
