phpMyAdmin upgrade

I've attached zip with patched phpMyAdmin-2.11.?9.5-all-languages and script to migrate settings from phpMyAdmin-2.8.2.4 installed with Plesk. To install phpMyAdmin 2.11.?9.5 you need to:

1. Download the archive and unpack it.

~# wget http://kb.odin.com/Attachments/...phpMyAdmin.zip
~# unzip phpMyAdmin.zip

2. Extract patched phpMyAdmin:

~# cd phpMyAdmin
~# tar -xzf phpMyAdmin-2.11.9.5-all-languages.tar.gz

3. Migrate settings from installed phpMyAdmin to new one:

~# cd phpMyAdmin-2.11.9.5-all-languages && sh ../migrate_settings.sh

4. Backup files of installed phpMyAdmin (you can remove it later):

~# mv /usr/local/psa/admin/htdocs/domains/databases/phpMyAdmin /usr/local/psa/admin/htdocs/domains/databases/phpMyAdmin.old

5. Move files of new phpMyAdmin to Parallels Panel root directory:

~# cd ../
~# mv phpMyAdmin-2.11.9.5-all-languages /usr/local/psa/admin/htdocs/domains/databases/phpMyAdmin

When PHP is running as CGI, it cannot create sessions in default sessions directory

Plesk 9.2.1/9.2.2

When enabling cgi/fastcgi php runs under the ftp user.
php.ini states default path:

# cat /etc/php.ini | grep session.save_path
session.save_path = "/var/lib/php/session"

# ls -dl /var/lib/php/session/
drwxrwx--- 2 root apache 4096 Jul 17 09:01 /var/lib/php/session/

# rpm -qf /var/lib/php/session/
php-5.1.6-23.el5

FTP user is not allowed to write in the sessions directory. This means that customer who run php in cgi can not use sessions.

Hosting cannot be created if server is behind NAT and DNS template pre-configured

Plesk 9.x

Hosting cannot be created if server is behind NAT and DNS template pre-configured with real IPs.

You have server behind NAT and need to host domains on fake IPs, but DNS
records should refer to real external IPs.

You configure global DNS template and set real IP in A records instead of <ip>.

When you create a domain with physical hosting, the following error appears:

Can't manage hosting: Unable to set current ip address: IP address is missing.
You should look on doman's DNS settings (domain seems to be not created
properly)

0: /usr/local/psa/admin/plib/ui/client.domain.hosting.setup.php:133
plesk__client__domain__hosting__setup->accessItem(string 'POST', NULL null)
1: /usr/local/psa/admin/plib/UIPointer.php:596
UIPointer->access(string 'POST')
2: /usr/local/psa/admin/htdocs/plesk.php:36
