Copy from folder to folder preserving everything

Either use

sudo cp -rp /home/folder /media/backup/folder

sudo cp -a /home/folder /media/backup/folder (UPDATE: use this one!!!preserves everything)

Or use:

 rsync -avz

-p     same as --preserve=mode,ownership,timestamps

 --preserve[=ATTR_LIST]
          preserve the specified attributes (default: mode,ownership,timestamps),
          if possible additional attributes: context, links, xattr, all

Linux – copy all files from one folder to another with hidden (.dot) files

Leave a reply

Simple, use:

cp -r /source/. /destination

This command will transfer all files including hidden ones (for example I usually need .htaccess for my sites to be transfered as well).

Dedicated/VPS test speed

Very nice find. You can check various speeds from your server with this little script.

I have checked it and it’s working just fine. Kudos to the developer.

DirectAdmin skin upgrade/downgrade

Leave a reply

I have installed new vps with directadmin control panel. Tried to log in and got myself into new skin. I do like it but I’m old kinda type of programmers…I like it to be simple. All those ajax calls I don’t actually like.

To cut the long story short…go to resellers…skin manager…and then setup global skin and apply to all.

DirectAdmin transfer

Leave a reply

I have just transferred directadmin server to server. It was, well, easy I would say. If you know what you are doing then it is.

Server had CSF installed as well.

First use DA admin backup on server A, transfer via ssh to server B, then use restore on server B from DA admin/restore backup. Use new IP address from the dropdown list. Backup CSF and transfer it to the next server (follow the path when backing up…correct folder).

Next, on the server A revoke Let’s encrypt for domain name server (IP you have used for nameserver): https://help.directadmin.com/item.php?id=2084
Then install Let’s encrypt: https://help.directadmin.com/item.php?id=648
Then this: https://help.directadmin.com/item.php?id=629

Then install CSF from here https://help.directadmin.com/item.php?id=527. Use option 3. Restore previously CSF backup.

Next, install custombuild plugin.

Next, I like to use this tool for installing PECL extensions.

Next, enable forced SSL for each domain.

DirectAdmin changing nameserver and redirecting to new domain name instead of IP

Leave a reply

I had a problem. I needed to change domain name of the server – aka nameserver. It was already using some other name so the problem is there. After changing nameserver it didn’t work. It was redirecting me back to the old nameserver.

Solution:

https://help.directadmin.com/item.php?id=405
You need to update let’s encrypt with the new nameserver ( https://help.directadmin.com/item.php?id=629 )
https://www.directadmin.com/features.php?id=801
Mass update dns for all domains – https://help.directadmin.com/item.php?id=141

That’s it.
