Bellman is a Debian Linux server. It is on a UPS and lives in my studio.


"What's the good of Mercator's North Poles and Equators,
Tropics, Zones, and Meridian Lines?"'
 So the Bellman would cry: and the crew would reply
"They are merely conventional signs!"
--Lewis Carroll, The Hunting of the Snark

Packages I installed on Debian Stretch

curl
emacs-nox
yaml-mode
dnsutils
locate
net-tools
postgresql-client
rsync
sudo

I kind of want to be able to send email so I install 

postfix mailutils

Containerization

Read this https://docs.docker.com/install/linux/docker-ce/debian/ to set up the repo, like this 

apt install apt-transport-https \
   ca-certificates \
   curl \
   gnupg2 \
   software-properties-common
curl -fsSL https://download.docker.com/linux/debian/gpg | sudo apt-key add -
add-apt-repository \
  "deb [arch=amd64] https://download.docker.com/linux/debian $(lsb_release -cs) stable"
apt-get update
apt install python-pip

Finally, note use pip to install not apt -- versions are too old. 

sudo apt install docker-ce
sudo pip install docker-compose
sudo pip install docker-py

Firewall

See https://blog.daknob.net/debian-firewall-docker/ for ideas.

I use my own bash script to load iptables rules. See /usr/local/bin, /etc/network, and /var/lib/vastra.

Notes on printing

The Brother drivers provides for Linux for my HL-L2320D printer don't work, so I set up a raw driver on Bellman and then use the appropriate driver (manually selected) on client computers. It works fine.

Allow remote access

cupsctl --remote-admin --remote-any --share-printers

I also had to edit and add to /etc/cups/cupsd.conf 

HostNameLookups on

and then 

systemctl restart cups

Back ups

Disk 

sudo mkdir bellman
bwilson@bellman:/green/BACKUPS$ cd bellman
bwilson@bellman:/green/BACKUPS/bellman$ sudo rsync -av --exclude proc --exclude /var/tmp -exclude /proc --exclude /sys --exclude /dev --exclude /home --exclude /green / .

Back up mysql - important ones are asterisk and owncloud, everything else can go. Well okay I guess maybe phpmyadmin can stay too. 

sudo mkdir bellman_mysql
cd bellman_mysql
for i in asterisk mysql owncloud phpmyadmin yaris ; do 
  mysqldump $i > $i.sql
done

BBR congestion

See https://www.cyberciti.biz/cloud-computing/increase-your-linux-server-internet-speed-with-tcp-bbr-congestion-control/ for example.

Is kernel ready?

sudo -s

That's that.

Services that run here

  • git (see Running my own git server)
  • gpsd welll --- not in Astoria, not yet anyway. No antennas in this rental. :-(
  • cups to share Brother and Canon printers
  • ssh to allow remote access
  • fail2ban to cut off break in attempts via ssh

I wasted time trying to get "nut" installed to monitor the Cyberpower 1500AVR and failed. It's not worth the effort. (2017-09-07)

Network syslog

To allow devices such as [[Granstream GXV3240] phones to spit out logging information, I enable rsyslog from remote hosts: In /etc/rsyslog.conf you must uncomment 2 lines and restart rsyslogd: 

# provides UDP syslog reception
module(load="imudp")
input(type="imudp" port="514")

Services that run in Docker containers

Install Docker: https://docs.docker.com/install/linux/docker-ce/debian/

Set up /etc/default/docker - use this 

DOCKER_OPTS="--dns 192.168.123.2"

Use the docker "--restart" option to run services, it's far easier than messing with systemd config files.

= service notes
Asterisk in Docker always a work in progress
ElasticSearch Kibana and ElasticSearch in compose.
GeoServer includes PostGIS, GeoServer, NGinx in compose.
Streaming media Logitech squeezebox server SqueezeBox See Streaming media for installation notes.
Owncloud server linked to the mysql container.
MySQL for asterisk and Owncloud

Other things come and go, I am working on the GeoServer docker services now.

Router migration

First I had a Mikrotik router (RB750GL)

Then I ran Bellman as the router for a few years

Currently I use a Ubiquiti EdgeRouter-X

Bellman as a router

I dumped my little Mikrotik router and then used Bellman as a router and firewall. The main reason was that MT does not support OpenVPN over UDP and I needed to set up a connection to a remote site with OpenVPN. I want to do site-to-site (not machine-to-machine).

  1. DHCP migration was easy.
  2. DNS migration: same
  3. Firewall: meh, probably easier to maintain in Bellman, I have scripts there already; replicated the same rules

DHCP migration

I had to open port 67 on Bellman's firewall, after that it was done.

See /etc/dnsmasq.d/wildsong.biz

DNS migration

I read out the mappings from the MT and put them into /etc/hosts and it works.

Since dnsmasq is doing DHCP on Bellman, it catches names when devices register and puts them into DNS too. Slick.

Firewall migration

Most of the Mikrotik port forwarding rules simply passed traffic to Bellman, so instead of NAT I have to open outside ports for access to Twilio. I had already done that as part of the Vastra installation.

These services run on Bellman, so they no longer require NAT and port forwarding. This makes life a lot easier.

  • SIP over TCP
  • SIP over UDP
  • RTP for VOIP
  • IAX (disabled)
  • HTTP

Bellman has to do NAT for LAN traffic outbound.

To configure the firewall, I implemented two bash scripts, one fires on eth0 (LAN port) and the other fires on eth1 (WAN port).

I continue to use eth0 as the LAN port and I put DHCLIENT onto eth1 and it is the WAN port.

OpenVPN configuration

History

2019-10-03 - Upgraded to Debian Buster (10) and this broke Docker because of the move from iptables to nftables. Must fix ASAP. All Dockers are broken. How dismaying. Repeat after me: "It's only a hobby."

2019-05-09 - Added docker-compose for elasticsearch and per recommendations of ElasticSearch docker docs, changed vm.max_map_count; it was 65530 and I set it: sysctl -w vm.max_map_count=262144

2019-04-26 - Moving NVMe WDC Black drive from Murre to Bellman.

2018-03-20 - Installed 8TB Archive drive, for TimeMachine and Owncloud storage. Moved from 120GB SSD to 750GB Samsung Evo 840. Installed clean copy of Stretch on the SSD.

2017-09-06 - Upgrade to 32GB RAM, yay! I need to do something with all that space. I did move /tmp to RAM; see SSD optimizations. I also removed a lot of dead code including lightdm (how'd that get in there?)

2017-08-25 - Migrated mariabdb and owncloud to Docker

2017-07-25 - Migrated logitech media server to Docker

2017-07-25 - Upgraded to Debian 9 (Stretch)

2016-10-16 - Seeing disk errors in the WDC. It's 6 years old! REPLACE!!! Installed new Seagate Barracuda ST2000DM006 2TB $70 10-26-16 Added a fan in the hard drive section of the case, too.

2016-01-26 - Installed VirtualBox 5.0.14 and Vagrant 1.8.1 (from DEB files, repos are too old) and started migration of services.

2015-12-?? - Moved to hardware formerly used for Vastra2

2015-07-10 - Added lm-sensors and added temperature tracking to Cacti.

2015-07-01 - Replaced APC UPS with Cyberpower. Installed monitoring software.

2015-06-19 - reconnected the MX330 printer and shared it.

2015-06-18 - upgraded to Debian 8 Jessie

2013-12-29 - returned from X-Mas and discovered Bellman won't boot. Snarks about a degraded RAID. Darn.

2013 Mar - Installed Linux Mint 14 so that I could use Makerware with my new Replicator 2

2013 Jan - Seagate Barracuda 2TB Green drive died. ST2000DL003 S/N 5YD77CTE Replaced with a Barracuda 2TB mirror

2011 Dec - Been doing PostGIS experiments so I upgraded the hardware.

2010 Jan - I just started this section but I have had this machine online for at least a couple years now.

2015-06-19 back up

Note this includes /home but not /green. 

cd /
tar --one-file-system czvf /mnt/bellman_root.tar.gz .

2013-12-29 Rescue from boot fail

I no longer need a desktop environment on the small server, because I moved my main desktop next to the 3D printer. So I put Debian back on the server again. So I am going to try a Debian rescue image.

Diagnosis

Step 1. Build rescue thumbdrive. Download from http://debian.osuosl.org/ and copy image to thumbdrive 

sudo cp debian-live-7.2-amd64-rescue.iso /dev/sdX
sudo sync
sudo eject /dev/sdX

where X is the appropriate drive letter, do NOT use the wrong letter!

Step 2. Boot Bellman with the thumb drive

Step 3. Look around

Using hdparm -i

  • sdb Seagate 2TB ST2000DM001-9YN164 S/N Z240BVP5

Looks like there are 2 RAID's, and md126 is the broken one. It should be the SSD and something else? Time to open the box and see what's in there.

Conclusion - I was planning on doing RAID mirror and never got the second drive installed. I think I might have used it in Stellar instead. Steller's drive failed and needed immediate replacement. Something failed on the SSD and now it's not booting, but this has nothing to do with the hardware from what I can tell. It complains about the RAID missing a drive but that's not new.

2014 Jan 01 rebuild

Do as in the Linux Mint section below

Also note:

PRESERVE MYSQL!!

/etc/hdparm.conf

2013 Jan data mirror build

apt-get install mdadm lvm2

mount /dev/vg_mirror/lv_mirror /green
dd if=/dev/zero of=/green/swapfile1 bs=1024 count=1048576

2013 Mar Linux Mint rebuild

Had to install mdadm and lvm2 but then it recognized the LVM drives All I had to do was mount the RAID on /green.

sudo apt-get install synaptic nfs-kernel-server ssh mysql-server phpmyadmin ntp winbind smartmontools postfix

Re-install dropbox

Re-install squeezeboxserver from Logitech. http://bellman:9000/

Set up cups again

Copy over /etc/exports file

Need AFP support for Apple Timemachine. See Netatalk 3 on Debian

December 2011 upgrade

Bellman had an Intel Little Falls Atom 230 mini-itx main board + 2GB RAM until Dec 2011. Bellman used to be an Athlon desktop system, I recycled the name because I like it.

Bellman is configured to bring up a management interface on this ethernet interface too. (Optionally there is a separate management interface. This server has 5 ethernet ports, 4 on the motherboard and 1 on the management card.) Since it's a Supermicro possibly it can be pwned at any time by the Chinese. Since I don't use Bellman to control centrifuges or do weapons research I live with it.

Operating system

  • Debian 9.8

Using BTRFS now on the Seagate drive. Sort of just to be consistent with what is on Tern though this is not RAID 0. Just one drive. I partitioned the Seagate this time, partition 1 could be a 50GB OS install, 2 is 50GB swap, and 3 is data (/green)

Software


Media server: it hosts my music collection. I keep the files in MP3 format, having transferred them from my CD's using grip. Music collection

File server: I use Samba in Docker to mount my home directory on Windows machines. NFS is available for 
accessing Bellman from Macs.

I edit files with emacs23



Spin down the Seagate drive


To reduce wear on the spinning hard drive,
I am setting "apm" down to 127 (default is 254) so that it can spin down the drive.
I use the server mostly for ownCloud and media storage so it can go to sleep at night and during long breaks
this should make it last longer.

Automatic boot


I know it's possible to get this system to boot every day at a specific time because it's set to do that right now.
I cannot find the setting! It's not in BIOS anywhere that I can see and I can't find in ipmitool either.

Sometimes I shut Bellman down at night, but it needs to boot in the morning before we get up
so that the Logitech radio will work. The way to set it is NOT from BIOS, there is no user interface there.
It's not from the IPMI web page either.

Maybe it's in here http://www.accuratesolution.net/asd/resume.htm



IPMI


Tips from Oracle: http://docs.oracle.com/cd/E19464-01/820-6850-11/IPMItool.html

Using ipmitool you can connect remotely so if the system is off you can turn it on.
This means I could just script the turn on from another server... 



ipmitool -H 192.168.1.3 -U ADMIN -P password chassis status
System Power         : off
Power Overload       : false
Power Interlock      : inactive
Main Power Fault     : false
Power Control Fault  : false
Power Restore Policy : always-off
Last Power Event     : 
Chassis Intrusion    : inactive
Front-Panel Lockout  : inactive
Drive Fault          : false
Cooling/Fan Fault    : false
