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

Yep, I have this installed and working on 4.0.2

[Sador]

Some kind of quick IP banner from the postbit (banning the IP of that post) would be a nice feature.

Anyway, it's a nice mod.

[wolfyman]

where do I enable this for a usergroup?

I want my super mods to be able to use it, but I can't find that setting!

[ViktorDA]

Thank you.
Installed.

did you figure out where to give access to this tool by usergroup?

[Carnage]

This is an admin cp tool; for someone to access it they need to be a) an admin and b) be given the admin permission 'Can Administer Ipbans'

I am having a problem with this mod. My web servers run on 32 bit systems, I believe PHP is having a problem with the use of bitwise operators because of this. Any suggestions?

[Carnage]

IP's are 32 bits; so it should be ok...

Can you describe the specific symptoms this is causing I may be able to come up with a work around.

[TheVoidz]

I believe the problem exists here;

PHP Code:

$ip=sprintf("%u",ip2long($vbulletin->GPC['ip']));
$cidrmask = ((pow(2,$vbulletin->GPC['cidr']) -1) << (32 - $vbulletin->GPC['cidr'])); //nb only works with ipv4. for ipv6 changes need to be made.

$ip = $ip & $cidrmask; 


Specifically with the last statement, and only when $ip is implicitly cast to a float(?). What happens is any ban above 127.255.255.255 results in PHP returning a maximum of 2147483647 not allowing anyone to ban anything above that range.

It works great for me, thanks for all your effort and hard work
