Connecting to FTP server setup in Cent OS 5

Hi all,

I need to deploy an Image on dell machines using Acronis True Image Home 10. I have set up a FTP server on Cent OS 5.0 system and copied the image file (dell_image.tib) on the FTP server. However, when I boot from Acronis CD and under 'recover' page, if I select FTP and type the IP address the 'Next' button stays greyed out. If I use different machine then I can connect to my FTP server using WinSCP.
Could someone please let me know if I am missing anything here.

Thanks,
Jenish
