For more secure server, we have to close some ports to users.

If need access to this ports, we can give permission to our IP address.  Please dont forget, “iptables” can be block all IP address but when you restart the server it will be clean all of this commands.

mod_status provides information on the Apache server activity and performance.

OpenSSH 5.7 released

Valic —  January 24, 2011 — Leave a comment

OpenSSH 5.7 has just been released. It will be available from the mirrors listed at shortly.

OpenSSH is a 100% complete SSH protocol version 1.3, 1.5 and 2.0 implementation and includes sftp client and server support.

Once again, we would like to thank the OpenSSH community for their continued support of the project, especially those who contributed code or patches, reported bugs, tested snapshots or donated to the project.

Changes since OpenSSH 5.6


* Implement Elliptic Curve Cryptography modes for key exchange (ECDH) and host/user keys (ECDSA) as specified by RFC5656. ECDH and ECDSA
offer better performance than plain DH and DSA at the same equivalent symmetric key length, as well as much shorter keys.

The Debian project is pleased to announce the eighth update of its stable distribution Debian GNU/Linux 5.0 (codename lenny).
This update mainly adds corrections for security problems to the stable release, along with a few adjustment to serious problems.

Please note that this update does not constitute a new version of Debian GNU/Linux 5.0 but only updates some of the packages included. There is no need to throw away 5.0 CDs or DVDs but only to update via an up-to-date Debian mirror after an installation, to cause any out of date packages to be updated.

Those who frequently install updates from won’t have to update many packages and most updates from are included in this update.

New CD and DVD images containing updated packages and the regular installation media accompanied with the package archive respectively will
be available soon at the regular locations.

Upgrading to this revision online is usually done by pointing the aptitude (or apt) package tool (see the sources.list(5) manual page) to one of Debian’s many FTP or HTTP mirrors. A comprehensive list of mirrors is available at:

PhpMyAdmin by default allows you to import only 2 MB file. In many cases this is just way too little.

In order to increase the values you need to alter your php.ini settings. For example put these in your php.ini to import 50 MB files:

post_max_size = 50M
upload_max_filesize = 50M

You can also create a .htaccess file with the above contents in the phpMyAdmin directory:

php_value post_max_size 50M
php_value upload_max_filesize 50M
