I got my “FRITZ!Box + LTE-Modem” set-up re-established again
- FRITZ!Box 7490
- Huawei E3372 “Surfstick” knows LTE and also UMTS (and so forth (I think))
- http://www.amazon.de/Huawei-E3372-Modem-microSD-weiss/product-reviews/B00M2JO9LI – these reviewers (and also myself) confirm, that these 2 devices work together well
- I had lost that modem (together with its SIM card) a couple of months ago, but I got new ones right now, and everything is fine again
- FRITZ!Box 6842 – has a builtin LTE modem, but my experiences with it are “diverse” – with decent LTE coverage everything is fine, if the LTE coverage is in trouble, the 6842 is of now use – under the same circumstances, the 7490+E3372 combination still works fine
- I need a decent mobile Internet set-up for my “office in exile desk” situation
- to be clarified: try this LTE modem also with my Synology DiskStation – I mean the most recent slim 1-bay one – if that combination works, and the DiskStation successfully acts as a mobile wifi router, then this is my leanest set-up I can figure these days

Synology DiskStations – ordinary user accounts cannot have bash as a default shell to SSH into
- http://serverfault.com/questions/458553/cant-log-in-via-ssh-to-any-accounts-set-to-use-bin-bash-as-a-default-shell
- Synology employs a customised version of ssh, having a modified C function “IsAllowShell”, only allowing /bin/sh and /bin/ash
- in order to achieve my goal, I inserted this code into my $HOME/.profile (code coped and adopted from the discussion thread quoted above):
```
[ -x /opt/bin/bash ] && exec /opt/bin/bash -login
```

Synology’s latest “DSM” firmware update: 5.1-5022
Installed it last night on all my DiskStations:
```
$ /bin/uname -a
Linux DiskStation000 2.6.32.12 #5022 SMP Wed Jan 7 14:18:42 CST 2015 ppc GNU/Linux synology_qoriq_213+
Linux DiskStation001 2.6.32.12 #5022 Wed Jan 7 14:19:44 CST 2015 armv5tel GNU/Linux synology_88f6282_112+
Linux DiskStation002 3.2.40 #5022 Wed Jan 7 14:18:59 CST 2015 armv7l GNU/Linux synology_armada370_ds115j
```
It was funny to discover, they ever reflect the “5022” as “kernel version” of uname‘s output. And BTW: uname built into their BusyBox even shows the Synology model name – I am tempted to use that in my shell scripts, if it comes to discriminating Synology (utility) features like seq‘s deficiency.

Cacti network graphing / monitoring vs Synology DiskStations

Cacti (software)
- http://en.wikipedia.org/wiki/Cacti_(software)
Where to best run Cacti on?

My home office NAS? (Any NAS?) But my Synology NAS-s don’t have it in their software repositories.

My next favourite choice is the opensuse VM on my big fat Mac mini. It needs …

sendxmpp-1.24 got created rather recently (2014-09-13) – two .pm-s involved indirectly needed changes – and now it works for me
- http://sendxmpp.hostname.sk
The software also moved to a new maintainer.

Two modules involved showed warnings like this:

Use of uninitialized warnings …
- …/XML/Stream/Parser.pm – method: new
- …/Net/XMPP/Debug.pm – method: Init
They both have their github repositories:
- https://github.com/dap/XML-Stream
- https://github.com/dap/Net-XMPP
I forked them both, introduced my changes, and committed pull requests. I wonder, whether they will get accepted, and I also wonder, what it will take, so that the current tarballs resp. github ZIP downloadables will find their way to CPAN.

I created 2 accounts on jabber.de,
- one for initiating messages,
- one for receiving them.
Now sendxmpp works fine for me.

Update 2015-03-25: Uses these patches to install and run sendxmpp etc. successfull on a Synology DiskStation.

backing up my new openSUSE VM to my Synology NAS – using my beloved Ruby Rakefile

Of course the Rakefile needed a few changes, and it also got a few long awaited changes applied.

One VM like that on the Mac mini (alternate Special Edition) hosting the VM is like nothing. A new openSUSE, a new VM – with all the same minimal contents inside – that will be fun.

all my Synology DiskStations offer me a software update: “DSM 5.1-5004 update 2” – how exciting 😉
- https://en.wikipedia.org/wiki/Smoke_testing_(software)
- https://en.wiktionary.org/wiki/liber#Latin – the inner bark of trees, paper, parchment, book
My tiny little “smoke test” WRT “did the software / firmware update to my Synology DiskStation” succeed:
- can I access the respective https://diskstation999:5001/webman in my Firefox? (I am using Firefox for this, as it (usually) remembers the respective login credentials as opposed to Chrome, which doesn’t – I guess, the web page tells the browser to not offer filling in the credentials, and Chrome obeys to it and Firefox (ususally) doesn’t)
- can I ssh to it, and can I run “bash -login”?
- can I rsync to the other two DiskStations? – additional test on the primary NAS
Which one of my DiskStations got updated, in which order, how successful was the update, what trouble arose:
- DiskStation000 –DS213+, 2-bay, the one accessible from outside – success
- DiskStation001 – DS112+, 1-bay – success, but only after restarting Firefox – no idea, why
- DiskStation002 – DS115j, 1-bay, my prime “mobile” NAS – postponed, until everything with the other two is (almost) perfect – success
Before my primary NAS (002) gets updated:
- I back up my openSUSE Linux VM to 000+001+002
- I make double-sure, that I back up everything from 002 to 001 and 000, that I usually just back up to 002 itself and only to 000 and 001 once in a while: book library (sounds redundant, doesn’t it?!! “library” stems from the Latin word for “book” – see above!), music library, quicken banking, …

my primary NAS (Synology DiskStation DS115j) had a high CPU usage, so I restarted it
- https://www.synology.com/en-global/products/DS115j
I have been using it almost simultaneously from a couple of machines through AFS and NFS, so once access started slowing down, I thought, it’s better to have a look at it’s “Resource Monitor” – and yes, its CPU usage stayed above 95% for quite some minutes, so once I had my short term goal achieved, I restarted the box. Let’s see, how it will behave in the near future!
