I am running an intranet LAMP server that only needs to send email (not receive). I have been able to send to email addresses outside of my organization, but not to addresses internally (i.e., yourname@yourorg.com would work, but myname@myorg.com would not). I believe it had something to do with the internal nameserver conflicting with the public nameserver.

Anyway, applying the mv and touch to the main.cf file fixed the problem, immediately after a postfix restart. Thank you, been looking for days for a solution!

But some important security notations.

As you never should login and run normal work under root, you should never run as Administrator in MS Windows. It is a very efficient way of getting viruses and roots on your machine.

So that’s why you don’t want to allow root access to your NFS shares, as NFS isn’t that hard to fake if someone has are not that hard to crack if you use NFS2 or NFS3. And you will have unknown people in your local net if you have a WLAN access.
If you use NFS4 with Kerberos, you will get a much better protection with singel sign on and encrypted communication. But then again, I don’t know if SFU support that.

I usually use ‘ip add’ instead, as it is shorter and gives better information and can get/set much more information. Only needs to know one command

To print out all IP addresses on the maching, I can use this version, which prints out both ipv4 and ipv6 addres:

ip add show scope global | awk ‘/inet6?/ {print $2}’ | cut -d/ -f1

I have some problems about clonezilla.
I’ve done it as you showed in the video for imaging my disk to another usb hard drive (1TB free space, my c drive I wanna to be cloned is 160 gb. But the problem is when cloning is in progress about 34 percent completed, there is an error occured like I/O Buffer problem so imaging is cut off unfortunately.
What could be the problem ? Interesting one is everytime problem seem at the same stage I mean 34 percentage. Is that means problem about harddrive not the clonezilla software ?
My best regards,
