Raspbian + NFS

Install:



apt-get install nfs-kernel-server

nano /etc/exports

Once there, let’s add:



/mnt/flash *(rw,sync)

Dont’ forget to run exportfs!

Add New Services:

Here’s the deal: rpcbind must run before nfs-server. But due to a bug… that’s not the case. What happens if the sequence is not that?… simple! NFS is inaccessible.

In order to fix this, let’s do the following:



cat >/etc/systemd/system/nfs-common.service <<\EOF 

[Unit]

Description=NFS Common daemons 

Wants=remote-fs-pre.target 

DefaultDependencies=no 



[Service] 

Type=oneshot 

RemainAfterExit=yes 

ExecStart=/etc/init.d/nfs-common start 

ExecStop=/etc/init.d/nfs-common stop 



[Install] 

WantedBy=sysinit.target 

EOF





cat >/etc/systemd/system/rpcbind.service <<\EOF 

[Unit] 

Description=RPC bind portmap service 

After=systemd-tmpfiles-setup.service 

Wants=remote-fs-pre.target 

Before=remote-fs-pre.target 

DefaultDependencies=no 



[Service]

ExecStart=/sbin/rpcbind -f -w 

KillMode=process 

Restart=on-failure 



[Install]

WantedBy=sysinit.target 

Alias=portmap 

EOF

Raspbian + Transmission: Fixing “Connection refused on port 9091”

I’ve just managed to solve a quite annoying glitch. After booting Raspbian, Transmission was immediately unable to connect to transmission-daemon on port 9091.

After much digging, i’ve found out that:

– Restarting the service just makes things work
– I was getting a bunch of error messages in /var/log/daemon.log (re: bind)
– Several posts in few forums suggested that the service was being initialized before the network adapter was actually ready.

Long story short:

1. Launch raspi-config
2. Select: 3. Boot Options
3. Select: B2 Wait for Network at Boot

That’s all you need, pretty much. Next time you boot, transmission-remote-cli will be able to connect immediately.

Raspbian + Flash Drive + fstab

First off, you need to figure out the path of your flash drive:



fdisk -l

Then… edit /etc/fstab as follows:



/dev/sda1 /mnt/flash vfat rw,user,umask=0002,uid=1001,gid=121 0 0

Note that umask is… the “inverted” regular file mask. This represents 665 (because we’re evil). As per uid + gid, you can figure it out by means of this command:



id username

Update:

The best filesystem to use, if you need to maintain compatibility between the Flash Drive you’ll use with your Raspberry, and macOS, is probably ExFat. Now, problem is: Linux doesn’t really support ExFat by default.

So, we’ll need to install it, as follows:



sudo apt-get install exfat-fuse

In such case, your /etc/fstab file should look like this:



/dev/sda1 /mnt/flash exfat. rw,user,umask=0002,uid=1001,gid=121 0 0

Raspberry + Samba

Installing Samba:



apt-get install samba samba-common-bin

Once there, edit /etc/samba/smb.conf as follows:



workgroup = [your_workgroup_name]



[SHARE-NAME]

comment=Samba Share

path=/PATH/TO/YOUR/SHARE

browseable=Yes

writeable=Yes

only guest=no

create mask=0777

directory mask=0777

public=no

At last, setup the Samba password:



smbpasswd -a YOUR_USERNAME
