I think a few things has to be established here.
Do you understand a word of what above wrote? I love the guy, but I think I read between the lines that @mluna is not an extremely experienced user here. If I’m wrong, I apologize.
What you probably have to do is mount the network server (samba share) to a folder on your computer and THEN you can make folders “favorites” in dolphin and move between them.
I agree with above that you should make a systemd service to mount it.
He even wrote a guide about it, maybe he is shy, so I’ll post it for him. xD
Edit
Do the “SMB network share” part, including the credentials file and edit to fit your setup (workgroup can normally be excluded). I recomend creating it in your /home:
nano /home/YOURUSERNAME/.smb.cred and use that path instead of /etc/smb.cred (file becomes hidden in your home directory) in the .mount file. ie, if your username on your computer is mluna the path would be /home/mluna/.smb.cred
To change the credentials:
chmod 600 ~/.smb.cred
The systemd files are to go in:
/etc/systemd/system/YOUR_MOUNT_PATH.mount
Ie if you want to mount it at /media/yourshare, create a directory in /media called yourshare and the filename of the file will be media-yourshare.mount and .automount.
Create the directory:
sudo mkdir /media/yourshare
Edit/create the mount and automount files:
sudo nano /etc/systemd/system/media-yourshare.mount
ctrl+x then “y” and press “enter” to save.
Do the same to the .automount file.
Then activate the automount with:
sudo systemctl enable --now media-yourshare.automount
This means the network drive will not mount at boot but rather when ANYTHING is trying to access it, so if you f ex open dolphin directly after boot, the drive will be mounted and you can see it appear in the dolphin interface (make sure to remove your previous favorites connected to the “old” network drive before doing anything)
Edit 2
Add the uid=USERNAME,gid=USERNAME (with your username) to the options part of the .mount file (or it will belong to root), I have NO IDEA what they are talking about when stating “setting the ownership”, it’s a samba share, how would you chown that??
Blindly following that guide will not solve your problem, only solve one and implement another.
But if you do above modifications, it will work.
Feel a bit like an a** to just trow that tutorial at you now, hence the infinite number of edits. xD
