Modern ArchLinux on Dell T20

All what we need is:
  • Server - in my case it is underpowered Dell T20
  • USB 3.0 stick
  • Some hard drive
We are going to install base OS in following setup:
  • The hard disk will receive partitionless BTRFS file system
  • The USB stick will have GRUB plus boot partition plus some "future use partition".
Setup log:
  1. After booting USB installer, fix keyboard layout: loadkeys uk
  2. It is good to know haw devices were mapped (later fstab can use labels, but for now we need to know device names): lsblk -f
  3. Create BTFRS filesystem on main hard drive: mkfs.btrfs -L ARCH_ROOT /dev/sda
  4. Use gdisk to create GPT partitions for Grub - 1M of type ef02 and 512M of type ef00, rest of the disk will be used as spare partition gdisk /dev/sdb
  5. We shall format boot partition: mkfs.fat -F32 -n ARCH_BOOT /dev/sdb2
  6. After sync we can reboot.
  7. Now we shall mount our partitions:
    mount /dev/sda /mnt
    mkdir /mnt/boot
    mount /dev/sdb2 /mnt/boot
  8. Install the basic system: pacstrap /mnt base
  9. Generate fstab: genfstab -L /mnt >> /mnt/etc/fstab
  10. Change root to newly created filesystem: arch-chroot /mnt
  11. Set hostname: nano /etc/hostname
  12. Set timezone ln -sf /usr/share/zoneinfo/Europe/Belfast /etc/localtime
  13. Uncomment en_GB.UTF-8 in /etc/locale.gen
  14. Run locale-gen
  15. Put LANG=en_GB.UTF-8 in /etc/locale.conf
  16. Put KEYMAP=uk in /etc/vconsole.conf
  17. Run mkinitcpio -p linux
  18. Install grub: pacman -S grub
  19. Install boolader: grub-install --target=i386-pc /dev/sdb
  20. Configure bootloader: grub-mkconfig -o /boot/grub/grub.cfg
  21. Finally set password passwd
  22. You're done. exit chroot and reboot.

Hardening OpenWRT - adding non-root user account

I have at home an OpenWRT on TP-Link 1043ND. As I'm most of the time out of my home, I use this for two functions:  - as reliable WiFi Access Point  - as last resort remote access device  - as a box used to wake up other Ethernet enabled devices @ home. As this box is exposed to Internet via IPv6 address, I decided to harden it a little. 1. Adding extra non privileged user account: root@OpenWrt:~# opkg update root@OpenWrt:~# opkg install shadow-useradd root@OpenWrt:~# mkdir /home root@OpenWrt:~# useradd -D GROUP=100 HOME=/home INACTIVE=-1 EXPIRE= SHELL= SKEL=/etc/skel CREATE_MAIL_SPOOL=no root@OpenWrt:~# useradd -m -s /bin/ash bart root@OpenWrt:~# cat /etc/passwd root:x:0:0:root:/root:/bin/ash daemon:*:1:1:daemon:/var:/bin/false ftp:*:55:55:ftp:/home/ftp:/bin/false network:*:101:101:network:/var:/bin/false nobody:*:65534:65534:nobody:/var:/bin/false bart:x:1000:1000::/home/bart:/bin/ash root@OpenWrt:~# passwd bart Changing password for ...

Dropbear SSH keys and autossh on OpenWRT

Image
I have a box on Amazon EC2. And I want to have my OpenWRT that is behind IPv4 CGN and have public IPv6 to be reachable from IPv4 Internet. The best idea is to use ssh reverse tunnel connected with autossh to keep connection going. The very first think is to test if I can connect to my Amazon instance from my OpenWRT: root@OpenWrt:~# ssh 54.111.111.111 Host '54.111.111.111' is not in the trusted hosts file. (ssh-rsa fingerprint md5 0f:51:11:11:11:11:11:11:11:11:11:11:11:11:11:11) Do you want to continue connecting? (y/n) y root@54.111.111.111's password: At this point the public key of remote host will be added to .ssh/known_hosts. It is important as we can't have autossh to interact with console in future. root@OpenWrt:~# cat .ssh/known_hosts 2001:1111:1111:1111::1111:1111 ssh-rsa AAAAB3N....... 54.111.111.111 ssh-rsa AAAAB3N.......... Now we need to generate public/private key pair we will be using to connect to our Amazon instance. Invoke fol...

SSH Tunel with OpenWRT

You need to install OpenSSH client: root@OpenWrt:~# opkg update root@OpenWrt:~# opkg install openssh-client Now OpenSSH client replaced DropBear client: root@OpenWrt:~# ls -l /usr/bin/ssh -rwxr-xr-x    1 root     root        590667 May 24 14:54 /usr/bin/ssh root@OpenWrt:~# ls -l /rom/usr/bin/ssh lrwxrwxrwx    1 root     root            16 Aug 19  2016 /rom/usr/bin/ssh -> ../sbin/dropbear root@OpenWrt:~# ls -l /overlay/upper/usr/bin/ssh -rwxr-xr-x    1 root     root        590667 May 24 14:54 /overlay/upper/usr/bin/ssh Can you spot a difference: root@OpenWrt:~# ssh usage: ssh [-1246AaCfGgKkMNnqsTtVvXxYy] [-b bind_address] [-c cipher_spec]            [-D [bind_address:]port] [-E log_file] [-e escape_char]            [-F configfile] [-I pkcs11] [-i identity_file...
