Mount network share automatically on startup

Question

I'm trying to have two network shares automatically mount upon rebooting my machine but I'm having no luck. I've read through several similar AskUbuntu questions but I can't seem to get it to mount the shares on rebooting. This is my current configuration:

/etc/fstab:

//192.168.1.18/FileDepot    /mnt/FileDepot  cifs    credentials=/home/user1/.credentials,uid=1000,gid=1000,user,sec=ntlm    0   0
//192.168.1.18/Incoming     /mnt/Incoming   cifs    credentials=/home/user1/.credentials,uid=1000,gid=1000,user,sec=ntlm    0   0

In my home folder, I have the .credentials file:

username=user1
password=mypass

As I mentioned, this will not autmatically mount the shares on a reboot, but if I manually run:

sudo mount -a

it works.

I'm running Xubuntu 15.10 x64. Any idea what I'm doing wrong or missing?

Here is some output from dmesg:

[    5.077818] CIFS VFS: Error connecting to socket. Aborting operation.

I've tried using ethernet and no wifi, but that didn't help. I'm not sure where to go with this now.

Solution

I've been able to solve the problem on my system by adding x-systemd.automount, to the list of options in my fstab entry. I was seeing the same problem with Raspbian Jessie (from Wheezy) which led me to a forum post.

[Neil]

can you give me the out put of "ifconfig" and "cat /etc/network/interfaces"

[drohm]

@Neil I updated the question with the information you requested.

[Neil]

did you rename those interfaces to wlp4s0 and enp0s25

[drohm]

I didn't edit them, no. This is a clean install I did a couple days ago when 15.10 was released.

[Neil]

can you check if 70-persistent-net.rules file exists run "ls /etc/udev/rules.d/70-persistent-net.rules" if it exist can you post what is in the file.

[Neil]

Let us continue this discussion in chat.

[drohm]

I tried this and unfortunately it didn't work.

[drohm]

Thought that was it, but it didn't work on reboot. I can still do sudo mount -a and it will mount the shares without error. I just can't get it to mount on startup.

[drohm]

No change after reboot. What does that command actually do?

[Neil]

it Regenerates 70-persistent-net.rules file that file gives your interface name for your NIC's.

[drohm]

I've tried that, but it still doesn't mount.

[drohm]

I didn't explicitly ask for my home folder to be encrypted so I don't believe it is. I also tried specifying username and password in /etc/fstab to bypass having it look for the file and it still doesn't mount on reboot.

[drohm]

Thanks Matt. I'd give you an up-vote, but I don't have the rep yet.

[João Pimentel Ferreira]

Hi, could you give a more comprehensive answer? In which way and how shall you edit the file /etc/fstab? You just add a line with x-systemd.automount ?

Please be a little careful about using Copy and Paste answers across Ask Ubuntu particularly when you are giving a link to a particular application...
