Hi, I just made the machine be able to display chinese properly. First, choose a font from your windows directory, usually mingliu.ttc or kaiu.ttf. Since the chinese character db is huge, these files are usually a few mb in size. Copy a desired copy to /usr/share/fonts/ttf and run fc-cache -f -v thru terminal should be able to do it.

I pressed for any document that gives steps carried out when the “upgradeall” option is selected while upgrading from RHEL 5 to RHEL 6 but got the same reply, saying in-place upgrade is not supported across major releases.
Below is the list of steps I followed to get in-place upgrade...

Posted 08-16-2012 at 12:30 PM by ted_chou12

cifs not able to mount by hostname only by ip (solved)

Posted 08-15-2012 at 04:50 AM by ted_chou12

Hi! I recently found when I mount by hostname using cifs, it cannot resolve the hostname, but only IP, like the following:

Code:

root:# mount -t cifs "//NAS/main" "/mnt/share/NAS"
mount error: could not resolve address for NAS: Unknown error
vector://home/ted
root:# mount -t cifs "//192.168.1.101/main" "/mnt/share/NAS"
Password for vl70@//192.168.1.101/main:

I did a search and found this post:
