Bellman
Bellman is a Debian Linux server. It is on a UPS and lives in my electronics lab.
"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!"

Upgrade: Jessie to Stretch
2017-07-24 I wanted to try the new BBR queuing that I heard about yesterday in a Google announcement. It's been in the Linux 4.9 kernel so I looked up kernel versions for Debian and found out they released Stretch about a month ago. That means the easiest path to getting the new kernel is to upgrade Bellman from Jessie to Stretch.
Following advice on this page, https://linuxconfig.org/how-to-upgrade-debian-8-jessie-to-debian-9-stretch I am upgrading from 8.x to 9.x
The basic upgrade ends up leaving the 3.16 kernel in place, so I had to take extra measures to get the kernel upgrade.
I don't think I ever got these working; see notes on printing. I use a raw driver on Bellman and the Brother driver on clients (Laysan, Plover, Stellar, Swift)
dpkg --remove hll2320dcupswrapper:i386 dpkg --remove hll2320dlpr:i386
These were flagged as incompatible; Mongo was used by unifi which I will move into a Docker container soon. Samba was a convenience but I have not been using it.
apt-get remove mongodb-clients mongodb-server apt-get remove python-samba
Then we're ready to upgrade.
apt-get install linux-headers-4.9.0-3-amd64 linux-headers-4.9.0-3-amd64
Using "apt-get install linux-image-amd64" did not work; I could not get it to trigger the dependency on linux-headers-4.9.0-3-amd64 until I told it to install the specific version. This step required "repeal and replace" of 404 MB of packages; but it worked!
Files to check now (During kernel upgrade, I had to select either 'keep or update' and now I need to make sure they are okay.)
/etc/sysctl.conf /etc/cupsd-browse.conf /etc/cyrus.conf /etc/default/cyrus-imapd /etc/imapd.conf /etc/dhcp/dhclient.conf /etc/rsyslog.conf /etc/ssh/sshd_config /etc/fail2ban/jail.conf /etc/nginx/nginx.conf
I had to abort the failed phpmyadmin upgrade. I will remove it and either dockerize it or re-install it.
- This triggered the removal of unifi, which will be in a docker container soon anyway.
Other old things I removed
apt-get remove mutt gpsd roundcube phpmyadmin postfixadmin mediawiki cyrus-imapd tomcat8
Around this time I start wondering if my phone system will survive the changes. :-) Way past time to dockerize it anyway!
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

Sigh... printers... sigh... will have to deal with it again.
dpkg -C The following packages have an unknown foreign architecture, which will cause dependency issues on front-ends. This can be fixed by registering the foreign architecture with dpkg --add-architecture: hll2320dcupswrapper Brother HL-L2320D CUPS wrapper driver hll2320dlpr Brother HL-L2320D LPR driver
Not sure why I enabled backports. Will find out someday, perhaps.
BBR congestion

That's that.
Services that run here
I am in the process of migrating some of these services to run in Docker containers.
- Asterisk to run our phones
- ddclient updates DNS with our current IP address; see DDNS
- Festival for text to speech in Asterisk
- git (see Running my own git server)
- gpsd
- Nginx as a reverse proxy for dockerized services
- 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)
DOCKERIZED!
- Logitech squeezebox server SqueezeBox See Streaming media for installation notes.
- Owncloud server, linked to the mysql container.
- MySQL for asterisk and Owncloud
- Unifi to manage my Ubiquiti WiFi access point.
- Vault for secure storage of credentials.
Router migration
I dumped my little Mikrotik router and currently use Bellman as a router and firewall. The main reason is that MT does not support OpenVPN over UDP and I need to set up a connection to a remote site with OpenVPN. I want to do site-to-site.
- DHCP migration was easy.
- DNS migration: same
- Firewall: meh, probably easier to maintain in Bellman, I have scripts there already; replicated the same rules
- L2TP: in progress
First capture all existing settings from Mikrotik: can't be easier, just do an export like this:
ssh 192.168.1.1 export > mt_export_20170406
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.
L2TP migration

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

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.

Operating system
- Debian 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 keep my home directory here and NFS mount it on the desktop machine Raven. I removed Samba when upgrading to Stretch, I was not using it.
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
