Setting up trout (Debian home server)

Setting up my Debian home server.

File System

1. I keep /home in a seperate partition of the SSD so it was partitioned as follows:

   (parted)  print all                                                       
   Model: ATA ST2000LM007-1R81 (scsi)
   Disk /dev/sda: 2000GB
   Sector size (logical/physical): 512B/4096B
   Partition Table: gpt
   Disk Flags: 
      
   Number  Start   End     Size    File system  Name  Flags
    1      1049kB  2000GB  2000GB  ext4
      
      
   Model: Samsung SSD 970 EVO Plus 500GB (nvme)
   Disk /dev/nvme0n1: 500GB
   Sector size (logical/physical): 512B/512B
   Partition Table: gpt
   Disk Flags: 
     
   Number  Start   End    Size    File system     Name  Flags
    1      1049kB  538MB  537MB   fat32                 boot, esp
    2      538MB   151GB  150GB   ext4
    3      151GB   451GB  300GB   ext4
    4      451GB   500GB  49.6GB  linux-swap(v1)        swap
   

2. Create LUKS Volume We are going to use /dev/sda1 with encryption so:

     $ sudo apt install cryptsetup
     $ sudo cryptsetup luksFormat /dev/sda1
     $ sudo cryptsetup luksOpen /dev/sda1 img3
     $ sudo mkfs.ext4 /dev/mapper/img3
     $ sudo cryptsetup luksClose /dev/mapper/img3
   

3. Mount LUKS Volume. Use sudo blkid to identify /dev/sda UUID and create the following shell script:

     #!/bin/bash
     sudo cryptsetup luksOpen /dev/disk/by-uuid/XXXXXXXX-843f-42c9-af34-b5cb43f73d00 img3 
     sudo mount /dev/mapper/img3 /srv
   

   If you aren’t using encryption you can just directly mount the disk by adding the below to /etc/fstab:

     UUID=XXXXXXXX-463c-4ae6-827a-368ab73cad88 /srv ext4 defaults 0 1
   

   Then mount disk:

     sudo mount -a
   

4. Install samba

   $ sudo apt install samba -y
   

   In /etc/samba/samba.conf add:

   [troutshare]
      path = /samba
      writeable = yes
      browsable = yes
      read only = no
      guest ok = no
   

   $ sudo systemctl restart smbd
   

5. Install ssh sudo apt install openssh-server. Use ssh-copy-id user@machine to copy public key over.

6. To mount cod (mountcod script):

   $ sudo apt-get install cifs-utils time
   $ sudo mount.cifs  //cod.local/cod-share /srv/coddisk -o username=phwl
   

   Mounting others (mountall script)

   #!/bin/bash
      
   # /srv/troutdisk
   echo "Mounting trout"
   sudo cryptsetup luksOpen /dev/disk/by-uuid/f3bacd55-843f-42c9-af34-b5cb43f73d00 troutdisk
   sudo mount /dev/mapper/troutdisk /srv/troutdisk
      
   # /srv/coddifsk
   echo "Mounting cod (samba)"
   ./mountcod
      
   # /srv/wddisk
   EXTDISK=/dev/disk/by-uuid/5b5ac122-f46a-4307-8bfd-463bc9ca818a
   if test -f "$EXTDISK"; then
       echo "Mounting wddisk"
       sudo cryptsetup luksOpen $EXTDISK wddisk
       sudo mount /dev/mapper/wddisk /srv/wddisk
   fi
   

Backups

1. Set up backup cron job using crontab -e

   0 5 * * * /srv/troutdisk/scripts/backup-to-cod >/tmp/cronjob.out
   

   the script itself is

   #!/bin/bash
      
   function teval() {
      echo "-- $*"
      eval "/usr/bin/time -v $*"
   }
   
   echo "** Running $0"
   date
   teval 'find /srv/troutdisk -print > /srv/troutdisk/data/media/gen/WD3.index'
   teval 'rsync -avh --delete --progress /srv/troutdisk/ cod.local:/srv/coddisk/ima
   ge/3'
   teval 'ssh cod.local rsync -avh --delete --progress /srv/coddisk/ /srv/carpdisk'
   
   date
   

System

1. Disable suspend /etc/systemd/sleep.conf with the following options

   [Sleep]
   AllowSuspend=no
   AllowHibernation=no
   AllowSuspendThenHibernate=no
   AllowHybridSleep=no
