The mount must be a read/write access.

I've tried mount a hard drive with ntfs partion with the following commands in Xen server 7.0 :

fdisk -l 

Result

/dev/sdc1   *        2048   976769023   488383488    7  HPFS/NTFS/exFAT

Tried to mount NTFS

mount -t ntfs-3g /dev/sdc1 /mnt/

Result

mount: unknown filesystem type 'ntfs-3g'

PS.: I have based in this topic

I've Centos installed on a 32 bit system

Zimbra version

The following files :

AppBanner_black.png
AppBanner.png
AppBanner_white.png
LoginBanner_black.png
LoginBanner.png
LoginBanner_white.png
NotificationBanner.gif
NotificationBanner_grey.gif

The problem is when i access the mail by DNS the logos dont appear, but when i access the mail by IP the logos appear.

PS.: All the pictures have a access level for zimbra user

I have a web page deployed in server linux (Wheezy server version) and this web page generate a PDF file using a Arial font. I've looked at

/usr/share/fonts/truetype/ 

and there is no Arial font found there. Only:

DejaVuSans-Bold.ttf
DejaVuSansMono-Bold.ttf
DejaVuSansMono.ttf
DejaVuSans.ttf
DejaVuSerif-Bold.ttf
DejaVuSerif.ttf

How to install Arial font?
