debian Debian Quickstart

[Александр Рыжов]

You may use Debian 8.11 "Jessie" , Debian 9.13 "Stretch" , Debian 10.13 "Buster" , Debian 11.11 "Bullseye" or Debian 12.7 "Bookworm" right on your Keenetic router.

http://files.keenopt.ru/ is a good example of working Debian on Keenetic Giga III.

! Dropping mips architecture

! Debian 12.3 image release delayed

Requirements

• USB-port on router,
• Ext2/Ext3/Ext4 formatted flash drive or HDD. You may use EaseUS Partition Master free on Windows to format USB drive.

Installation

• Connect USB drive and get access to it via FTP or SAMBA,
• Make install folder on USB drive,
• Put debian-jessie-8_11-mipsel.tar.gz or debian-stretch-9_13-mipsel.tar.gz or debian-buster-10.13-mipsel.tar.gz or debian-bullseye-11.11-mipsel.tar.gz or debian-bookworm-12.7-mipsel.tar.gz file to Install folder,

           ( for KN-2011 or KN-2111 - debian-jessie-8_11-mips.tar.gz or debian-stretch-9_13-mips.tar.gz or debian-buster-10.13-mips.tar.gz ),

           ( for KN-2710 - debian-buster-10.13-aarch64.tar.gz or debian-bullseye-11.11-aarch64.tar.gz or debian-bookworm-12.7-aarch64.tar.gz)

• Open OPKG page, pick your USB drive and hit "Apply".

Give your Keenetic a couple of minutes to unpack necessary files, you''ll see following syslog messages if all went fine:

Using Debian

Use following SSH credentials to get access to Debian environment:

• host: my.keenetic.net,
• port: 222
• user name: root,
• password: debian.

This is it, you've got 10000+ available packages from one of greatest linux community!

For 64MB RAM devices is highly recommended to turn on Swap-file.

 

Details

You see chroot-environment after SSH logon, there's only minimal Busubox outside of it and /opt/etc/initrc script to fire up sandbox, this script starts necessary Debian services on boot and gracefully shut them down on reboot or unmount USB drive:

 

[I] Jul 19 10:28:36 root: Stopping Debian services...
[I] Jul 19 10:28:36 sshd[448]: Received signal 15; terminating.
[I] Jul 19 13:28:36 ndm: Opkg::Manager: /opt/etc/initrc: Stopping OpenBSD Secure Shell server: sshd.
[I] Jul 19 13:28:36 ndm: Opkg::Manager: /opt/etc/initrc: Done.
[I] Jul 19 13:28:36 ndm: Opkg::Manager: disk unmounted.

Also, you'll find /chroot-services.list file, where you can put new services which should be started on boot, please use one name per string, service names can be taken from  /etc/init.d.

Good luck!
