Topic: IPv6 support

[vivien]

Is this mod compatible with SMF 2.0.14 and PHP 7?

https://custom.simplemachines.org/mods/index.php?mod=3051 say compatible with SMF 2.0 and SMF 2.0.2

[d3vcho();]

Yes, it should be compatible with 2.0.14 as well. You'd need to emulate your forum's version to install it; How can I install a mod that doesn't work in my SMF version?

It should be noted this mod is not compatible with SMF 2.1's IPv6 support and all IPv6s will be lost during the upgrade.

The banning does not seem to work correctly. I saw other people also had this problem
When I add a new IPv4 ban I get the error: "The database value you're trying to insert does not exist: ip_low5"

Did someone manage to fix this?
Also existing IPv4 ban triggers are not shown in the ban trigger list.
They do seem to work, however i can't manage them.

Has anyone solved this?

[vivien]

This is problematic because some hosts no longer offer an option to disable IPv6.

I think that like for PHP 7, it should ensure compatibility for SMF 2.0 without waiting for SMF 2.1.

I block ipv6 with Forum Firewall and bad Behavior which both support ipv6 internally.

Is this mod compatible with SMF 2.0.14 and PHP 7?

I have it installed now on a SMF 2.0.15 running PHP 7.0.x and it seems its working for me (havn't tested it fully).

The only thing i have seen is that the following two errors are logged within the SMF Error Log during the  installation (posted previously in https://www.simplemachines.org/community/index.php?topic=440357.msg3904446#msg3904446):

2: mysqli_fetch_assoc(): Couldn't fetch mysqli_result
File: /var/www/forum/Packages/temp/database_install.php
Line: 64


2: Missing argument 3 for smf_db_change_column(), called in /var/www/forum/Packages/temp/database_install.php on line 49 and defined
File: /var/www/forum/Sources/DbPackages-mysql.php
Line: 285

Maybe this DB setup message could explain the missing database value here?:

When I tried to install this mode under SMF 2.0.15 it was not successfull.

The message I got:

Code: [Select]

Too few arguments to function smf_db_change_column(), 2 passed in /htdocs/smfforum.de/Packages/temp/database_install.php on line 49 and at least 3 expected

[Mr. Jinx]

This mod hasn't been updated for a looooooooong time, and contains some serious flaws. I would not recommend installing it.
If you need IPv6 support badly then you should be looking for other forum software. SMF is just not build for that.

[alexetgus]

This mod is obsolete. It is no longer compatible with the latest versions of PHP, SQL SGBD and SMF.
It's dammageable...

Hi @all,

I got the same error like rho_simafo and reported this at github.

What options are there to run SMF 2.0.15 on an IPv6 enabled Webserver ?

Right now I'm getting this error:

Incorrect string value: '''' for function inet_aton

Try the mod https://custom.simplemachines.org/mods/index.php?mod=3051 or upgrade to SMF 2.1

[wintstar]

Try the mod https://custom.simplemachines.org/mods/index.php?mod=3051 or upgrade to SMF 2.1

@vbgamer45, this does not fix the above reported errors. This mod you linked causes the error message.

This is problematic because some hosts no longer offer an option to disable IPv6.

I think that like for PHP 7, it should ensure compatibility for SMF 2.0 without waiting for SMF 2.1.

Since it still takes some time until SMF 2.1 is released, there should be a patch for SMF 2.0.17.

SMF 2.0 is still feature locked. we are not changing our minds on that.

This really needs to be reconsidered. Because it could become a security issue in 2.0.17. Each IPV6 address is recorded with 0.0.0.0.

[Kindred]

that is not the definition of a security issue...

There's another bug here  => $smcFunc['db_change_column']. The columns are not changed in the database table.    Maybe someone has a solution for that.
