Administrative and Maintenance Tools - Advanced Ipban Manager

What does this do?
This is intended as a replacement for the ip bans under vbulletin options. It allows for timed ip bans, cidr ranges and attatching reasons to bans.

It also features registration only ip bans allowing members who may be effected by an ip ban to continue using the forums, but blocking registrations and ip ban exempts so that you can ban a large range of ips and let through a smaller subset of them.

What can I use it for?
This is a much better tool for managing ip bans on your forums. As it has its own permissions, you can grant admins access to it without needing them to have full access to the vbulletin settings. For more details see the features list.

Features

• A new interface, separate to the options for adding and removing ip bans.
• Set expiry dates and reasons for ip bans
• See who set which ip bans
• Set ip bans by cidr range.
• Set registration only ip bans (great for stopping spam bots without affecting existing forum users)
• Set exempt ip bans (ban a large range of ips and only allow select ips through the ban)
• Define unbannable ips in config.php
• A range of tools for assisting usage including:
  • Cidr to range calculator (see what range a certain ban will affect)
  • Range to cidr calculator (creates a set of bans to cover any arbitrary range [experimental]
  • Test an ip (enter an ip to see if its banned or not and which if any bans affect it)
  • Whois an ip (get information on who owns (eg which isp) an ip and the cidr range of ips that they own (simplifying blocking users on dynamic ips)) [Dependant on host and server OS]
  • Check if a user is banned (enter a username/userid to see if they are banned or not)

Planned features

• Ban a user (some sort of integration and automation to ip ban users from their admincp profile)
• Integration with delete as spam feature to allow automatically ip banning spammers
• Inport/Export ip bans to share with others and amongst other sites you own
• Os independent whois and results parsing (eg give novice admins a hand in picking out the important bits)
• Automatic conversion from old bans into new ones.
• Phrases for admincp areas (that are currently lacking them)
• Integrated Admin help

PHP Code:

$ip=sprintf("%u",ip2long($vbulletin->GPC['ip'])); 


That line casts to an unsigned int should raise the max allowed value to 2147483647*2

Try replacing instances of

PHP Code:

$ip=sprintf("%u",ip2long($vbulletin->GPC['ip'])); 


with

PHP Code:

$ip=ip2long($vbulletin->GPC['ip']); 


but you will need to change the database coloum type from unsigned to signed.

[TheVoidz]

PHP Code:

$ip=sprintf("%u",ip2long($vbulletin->GPC['ip'])); 


Makes the $ip a string with a max value of 2147483647*2. Then when PHP needs to do arithmetic on the string it implicitly casts it to a float if it is larger then 2147483647 (for 32-bit systems) otherwise an int. On 64-bit systems PHP expands integers to 2^64.

Right, I had already figured out the problem. I removed the sprintf and allowed the AND to be done with the integers then printed it as an unsigned int in the query.

Your solution works perfectly.

I didn't realize that php would automatically convert back till I consulted the documentation following your issue the fix for 32 bit systems will be in the next release.

When i try to import md5_sums_ipbans.xml I get the following error

XML Error: Invalid document end at Line 16

using vb 4.0.3 Patch Level 1

[Carnage]

Thats in the uploads folder for a reason :P upload it don't import it, it stops vbulletin from seeing the mods files as being 'not a part of vbulletin' in the diagnostic tools, it also makes sure that the files that come with this mod have not become currupt.

[mordor1]

Tanks got the right file now Good mod :up:

Would it be too much to ask for specific instructions for setting permissions to make this feature available for a user account, or for the administrators group?

[Carnage]

In order to make this avaliable for a user, they must be an administrator. Then you need to edit their admin permissions and give them the can admin ipbans permission.

I can't fix the problem manually. so waiting for next release.

Does this work for vb 3.8.5?
Does this modification allow us to prevent blocking collective proxy IPs like AOL has? (blocking one AOL IP will block a mass of different AOL IPs)
