invalid User Agent

Hi,

I have a regular user has in the past week not been able to acces the site due to :

You have attempted to access this site with an invalid User Agent.

User Agent: none

I am trying to understand what constitutes an Invalide User agent ?

I have had the user check at: Only registered users can see links on this board! Get registered or login! and returned a user agent:
Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 2.0.50727)

any ideas why this user would now be resticted from accessing my site and what we can do to correct it. My other concern is that other user may also experience the same and I wouldn't know.

uncertain if this will solve your problem but do make sure your whole sentinel is up to dat,including the ip2country.

I've had the same issue this past week with a couple of users. I have done everything I can to bypass the check, in rnconfig, config and mainfile, and I updated ip2country.
Nothing worked for these users, even after I told them to delete cookies and files. However, when they switched to firefox the invalid ip problem went away.

Sounds to me like some form of PC-based anonymizer, either through some browser add-on (my bet given that FF worked), or some tool that was installed on their PC. Could also be the result of using an on-line anonymizer service.

Looks like I am going to have to look at this sometime very soon as a Spider I want to allow to crawl my site is getting stopped with this error message too.
I do not simply want to strip out the useragent check so I'm looking to find a way to bypass the check for a specific IP. I'm assuming no one else has looked at a fix for this yet so I'll get my hammer out tomorrow.

I'd like to set the checkip function back to true, too. But even with it as false, valid users are getting invalid agent errors... only IE users as far as I can tell.

I don't know this for sure, but does putting the IP range into the Protected range help? I just don't know personally for the user agent check. You would want it to just ignore the block and let it continue on.

I'm going to try with Protected and Excluded Ranges to see what happens.
The bot I need crawling my site is actually for context related ads and now I they responded to my support ticket and sent me a copy of the message their bot was getting, the inital 'block' was with my Spam Stopper module because their bot failed to me the criteria required to allow a pass-through. That bit was easy enough to fix, just added the IP to the modules whitelist.
I'll investigate some more later... back to painting.
