Yahoo is raiding my forum!

[Smith6612]

Look at what Yahoo is doing to my forum. I think I need to change my robots.txt file again.

 

[dWhite]

That's normal. Search engines have the ability to send out hundreds upon hundreds of spiders at the same time.

 

[Smith6612]

I know it's normal My home server still gets raided by search engines all the time, which is like once a week.

 

[bleachsk]

thats insane haha

 

[jodani]

That's shocking man

As you know, bandwidth is a precious commodity and not an infinite resource on free X10 Hosting.

So if you want to conserve some of that bandwidth by limiting your visitors to those humans that read and contribute to your forum, then you have 2 very strong tools to achieve this goal.

One you have mentioned is the robots.txt file but this is not always adhered to by those rude bots I call them, who, for log reading purposes, get the robots.txt file but then continue to spider your web site regardless of any restrictions they encounter in the robots.txt file, and I can assure you there are lots of those little beasties out there.

There are many examples out there of how to configure a robots.txt file to Disallow individual robots from accessing your site, also from individual files and folders, frequency of visits and a time gap between GET requests so as not to hog the available ports from your real visitors - if you need help with the robots.txt file then watch out for my next tutorial in the Tutorials Forum or do a Google for robots.txt.

So to really put the mockers on those or any non human robot who spider your site, then you can use the mod_rewrite directive in a .htaccess file in the web root of your site (public_html).

Here's how.
I have included these entries from my own .htaccess that is very successful in keeping my log files and my bandwidth under my control.

The list is quite comprehensive as it has been created and added to over the years and as such, some may cease to exist and those new faces on the block have yet to be added and will be if and when I see them in my site's log files.

You can pick and choose and add those that you feel ignore your robots.txt file and add those that don't even bother with the file at all which are mostly the spam bots looking for email addresses to add to a spammers joy.

This list has been, in my use, without issue for many years on just about every hosting service I have used, and incidentally owned, with most of them coming from my owned dedicated servers' log files.

So if you have any error issues with adding or editing your .htaccess file then check that you have not made a typo or a copy and paste error.

Make a backup of any existing .htaccess file before adding this list or parts of this list.

I can assure you also that it will not effect those human visitors you wish to have access to your site - but even they can be denied access, if they play up, in the same .htaccess file but by using a different directive.

RewriteRule .* - [F,L]

If you wanted to add Yahoo for example, then to keep it in alphabetical order , just place it after this entry like so:

RewriteCond %{HTTP_USER_AGENT} vayala [NC,OR] # dumb bot, doesn't know how to follow links, generates lots of 404 error pages
RewriteCond %{HTTP_USER_AGENT} "Yahoo! Slurp" [NC,OR] # bandwidth hog bot

Do likewise if you want to add more that you know of.

Or if you just want to add Yahoo to get you started and to test the waters so to speak, and maybe you feel Google is the only worthy search engine to use (Yahoo looks like it will be swallowed up by the greedy Micro$oft entity anyway) then just add this to your .htaccess file which can be the last entry in the file, after all others, if you wish:

RewriteEngine on 
RewriteBase /
RewriteCond %{HTTP_USER_AGENT} "Yahoo! Slurp" [NC,OR] # bandwidth hog bot
RewriteRule .* - [F,L]

I hope this helps to keep your log files and bandwidth under your control, it has for me, also I am in the process of creating a new tutorial for the Tutorials Forum but, as I pointed out, there are many bots that just choose to ignore your wishes and steal your bandwidth for their own greedy self interests, which is a pet hate of mine, especially if one is paying for that bandwidth.

Regards,
Rocky

Thanks for the .htaccess tutorial. If I ever need to use that, I'll be sure to check back here. As for me running out of bandwidth, all I have to do is change my domain name to point to my home connection. With my nightly downloads of my database and weekly backups of the home directory, if something happens, I just open those backups, throw them on the server and change the DNS on the domain, and I'm all set.

Yahoo is always on my forums, usually 2-5 spiders min. I am not sure why, but they must have a lot.

 

[DeadBattery]

Maybe they are trying to beat Google.

 

[Smith6612]

Yahoo probably does, as SMF 2.0 saw over a thousand cases of Yahoo being in my forum. That was quadruple the amount of Google. So yeah, there's two bots sitting in the forum right now, but it never leaves

check this page.
you can view the yahoo spiders on x10 forums.Hundreads of yahoo spiders are there at x10 forums too.This is a normal trend.

I will recommend you must not prevent yahoo from crawling your pages using .htaccess or robots.txt file.Because search engines are the door ways of your main traffic.Better you don't alter those spiders..

But you may prevent nasty or naughty spiders spidering your site.

 

[Smith6612]

I wasn't planning on blocking the bots. My Home server gets hit with stuff like this every week and it hardly uses any bandwidth.

This is a right decision..... keep on working good luck.:drool:
