VirtualBox 1.4 released, upgrade now

VirtualBox 1.4 released, download last version from here

For windows host click here

This new version brings hundreds of improvements, more than any update since the first official release in January 2007. Among the new features are full support for 64-bit Linux hosts, RDP session shadowing, clipboard synchronization and easier Linux host interface networking. In the storage department, VirtualBox now supports VMware disk images (VMDK) natively and can give virtual machines access to physical disks and partitions ("raw disk support"). The graphical user interface has received more polish and has now been translated into 12 languages (German, Spanish, French, Italian, Polish, Portuguese, Romanian, Arabic, Russian, Japanese, Traditional Chinese and Chinese). Red Hat Enterprise Linux 5 (RHEL5) and Xandros Desktop 4.1 are now officially supported; support for FreeBSD and OpenBSD guests has been improved.

As with its predecessors, VirtualBox 1.4.0 is available both as Open Source under the GPL as well as under a commercial license which, in most cases, allows you to use the product free of charge.

For user with 1.3.8 version, quick way to upgrade is by uninstalling 1.3.8 and reinstall 1.4, no reboot needed. (Forum)

I will try FreeBSD 6.2 and Solaris 10 in this release

hip..hip horray

/etc/rc.local and pure-ftp

pure-ftp already run in port 21 and other instance needed to make different server call

existing one controlled by /etc/rc.conf and I don’t know howto configure another one

after searching google I found clue about rc.local

by default rc.local not exist, I have to create one :

kongja# ee /etc/rc.local

put this lines :


/usr/local/sbin/pure-ftpd -S,212 -A -c50 -j -l mysql:/home/alamster/ftp/pureftpd-mysql_login.conf &

save by press Esc button

either execute it by typing :

kongja# sh /etc/rc.local

or by restarting  server then I can see two ftp service running . One using port 21 and another one using port 212

kongja# ps -ax | grep ftp
 1063  ??  I      0:00.03 pure-ftpd (SERVER) (pure-ftpd)
64979  p0- I      0:00.02 pure-ftpd (SERVER) (pure-ftpd)

 to make sure :

kongja# netstat -an | grep LISTEN
tcp4       0      0  *.21                   *.*                    LISTEN
tcp4       0      0         *.*                    LISTEN

great, I hope I not breaking anything by putting this line in rc.local :-)
