Into.the.Void.

The pet-project of GrRBL,which is an IP-based blacklist, The Greek Spammers Email Addresses Blacklist, previously described at a previous post of mine, has grown to 400++ verified addresses of Greek spammers.

From now on, apart from the usual rsync access to anyone who asks for it, there will be a public link on the web with a PGP/GPG signed list of the spammers for anyone to get. The public link will not update as often as the list from rsync, probably once or twice per month is enough.

For anyone who wants to read a bit more: http://grrbl.void.gr/#email_blacklist.

Direct link to the signed Greek Spammers Email Addresses Blacklist.

Don’t forget to read the disclaimer and to submit greek spam at GrRBL Submission.

phpMyAdmin is a great tool but a constant headache (xss, sql injections,etc) as well. Every now and then there are new security holes discovered that need to be fixed ASAP. On the other hand, Plesk doesn’t seem to follow these security fixes, so if you want to keep yourself a bit more secure than Plesk thinks you should be, then you have to upgrade phpMyAdmin by your self. This procedure isn’t very straightforward due to the way Plesk uses PMA so I’ll post here some notes/guidelines on how to achieve that.

My notes are based on Plesk 8.6, so I am sure newer Plesk versions are way easier to upgrade than this.

Step 1: Download new phpMyAdmin
# wget http://downloads.sourceforge.net/project/phpmyadmin/phpMyAdmin/3.3.8/phpMyAdmin-3.3.8-all-languages.tar.gz
Step 2: Extract into /opt/psa/admin/htdocs/domains/databases/

# mv phpMyAdmin-3.3.8-all-languages.tar.gz /opt/psa/admin/htdocs/domains/databases/
# cd /opt/psa/admin/htdocs/domains/databases/
# tar zxf phpMyAdmin-3.3.8-all-languages.tar.gz

Step 3: Rename old PMA and symlink the new

# mv phpMyAdmin phpMyAdmin.old
# ln -sf phpMyAdmin-3.3.8-all-languages phpMyAdmin

Step 4: Copy old config file
This step depends on your old PMA version. Since my version was 2.8.2.4 I had to:
#cp phpMyAdmin.old/libraries/config.default.php phpMyAdmin/config.inc.php
If you have newer versions of PMA just do:
#cp phpMyAdmin.old/config.inc.php phpMyAdmin/config.inc.php
Step 5: Edit necessary files
Substep a: edit phpMyAdmin/libraries/session.inc.php
When the first comment block finishes and before line 14: if (! defined('PHPMYADMIN')) {
add the following snippet:

// Close Plesk's session.
$proxy_session_id = session_id();
@session_write_close();
unset($_SESSION);

Substep b: edit phpMyAdmin/libraries/common.inc.php around line 190 and change:

    'error_handler',
    'PMA_PHP_SELF',
    'variables_whitelist',
    'key'
);

to

'error_handler',
    'PMA_PHP_SELF',
    'variables_whitelist',
    'key',
    // from Plesk
    'PHP_SELF',
    'db_host',
    'db_port',
    'db_user',
    'db_pass',
    'db_name'
);

!! Mind the “,” after ‘key’ !!

That’s about it…you should now be able to use your new PMA version through Plesk.

Since Leaseweb, the hosting company where void.gr’s server is located, isn’t yet ready to provide native IPv6 to dedicated servers, I decided not to wait for them any longer and to set up an IPv6 tunnel to tunnelbroker.net so that I make void.gr accessible over IPv6.

Setting up the tunnel is extremely easy. Having the following in my /etc/rc.conf does the trick:

ip tunnel add he-ipv6 mode sit remote 216.66.84.46 local 85.17.162.131 ttl 255
ip link set he-ipv6 up
ip addr add 2001:470:1f14:e0a::2/64 dev he-ipv6
ip route add ::/0 dev he-ipv6
ip addr add 2001:470:1f15:e0a::1/64 dev eth2

Yes, I know I could have used some of debian’s config files for these parameters…Oh and you “ifconfig” users, time to give up using that ancient tool, it’s time you learn how to use “ip”.

So for you people who have IPv6 connectivity, just try it. The current IP of void.gr is 2001:470:1f15:e0a::1. Ping6 it 🙂

Time is ticking away…bye bye IPv4: http://ipv6.he.net/statistics/
