NAME
blog.hoberg.ch - useless things for everybody
DESCRIPTION
blog.hoberg.ch is a text mode blog about BSD, Linux and typical DevOP content.
OPTIONS
- Ansible module CRAN plugin
Created a new Ansible module to enable package managing for CRAN (Microsoft R Open) modules. This will let you
(un)install single or multiple packages even from custom repositories.
Example of usage:
- name: Install multiple packages from CRAN
cran:
state: present
package: vioplot A3
GitHub: cran.py
GitHub upstream: #42046: PR cran.py
- Ansible module yum_versionlock plugin
Created a new Ansible module to enable yum-versionlock functions in Ansible. yum-versionlock is a Yum plugin that takes a set of
name/versions for packages and excludes all other versions of those packages. This allows you to protect packages from being
updated by newer versions. There's a PR open to merge this into upstream.
Example of usage:
- name: Prevent Apache / httpd from beeing updated
yum_versionlock:
state: present
package: httpd
GitHub: yum_versionlock.py
GitHub upstream: #41778: PR yum_versionlock.py
- Ansible: java_cert module with trustcacerts option
When working with custom java key-/truststores you may find a new option to Ansibles java_cert module to trust an
imported certificate as trusted CAcert. This'll be needed when there's no chain of trust. With this PR there's no
workaround with keytool and command module nessesary.
Usage of task:
- name: Import trusted CA from SSL certificate
java_cert:
cert_path: /opt/certs/rootca.crt
keystore_path: /tmp/cacerts
keystore_pass: changeit
keystore_create: yes
state: present
cert_alias: LE_RootCA
trust_cacert: True
Github: #37708 Pullrequest
Download: java_cert.py
- postgresql-common 189 RPM for CentOS 7 with PGSQL10 support
Precompiled postgresql-common (build 189) RPM package for RHEL/CentOS 7 with PGSQL 10 support.
Changelog:
- New upstream release 189 (includes PGSQL 10 support)
- Fix systemd unit file for CentOS 7
Download: postgresql-common-189-1.el7.centos.noarch.rpm
- Stravlexa - An inofficial Alexa Skill for "Strava" Webservice
Sunday's morning while breakfasting - your mobile or tablet isn't in your kithen and you want to know your
last information from your sport activities? Ask Alexa! This Skill will provide basic information like your
weight your calories and your last activities like weightlifting, running biking and swimming with your last
30 activities on Strava. This Skill will need an API token which can be generated on Strava Settings.
Update: Version 1.1 supports all activity types of Strava.

- Ikea Tradfri Gateway firmware 1.2.42 broke coap connections with dynamic DTLS identities
After watching a movie this evening my final workflow didn't start as usual (shutdown TV
and enable overhead lights at 30%). After debugging without any success for the given
401 Unauthorized messages, I found out that my Ikea Tradfri gateway got silently updated to
version 1.2.42 with an interesting changelog to support DTLS sessions for CoAP.
Home Assistant got notified by Ikea and posted a hint on Twitter which made
it easy to fix my Homebridge (@NorthernMan54 Homebridge fork for Alexa support) and the
homebridge-tradfri plugin. As a quick fix you may generate your uniqe credentials
that'll stay for lifetime:
/usr/local/bin/coap-client -m post -u "Client_identity" -k "YOUR-TRADFRI-GW-PSK" -e '{"9090":"FOOBAR"}' "coaps://10.2.2.2:5684/15011/9063"
You will get something retunred like:
{"9091":"cKwtcUffs34gFfnhfJ","9029":"1.2.0042"} # cKwtcUffs34gFfnhfJ is our interesting part
Now, requests can be send by:
coap-client -m get -u "FOOBAR" -k "cKwtcUffs34gFfnhfJ" "coaps://10.2.2.2.51:5684/15011/9063"
When running any plugin based on coap, remember to replace your gw key and user with your new ones e.g. on homebrdige-tradfri:
--- tradfri/coap.js.bak 2017-11-01 02:27:50.141793626 +0100

- Wildfly/JBoss 10/11: Serve multiple webapps on different ports with vhosts
There're many HowTos out in the web how to serve multiple Webapps on
different ports, but the most of them will tell you to duplicate your
systemd unit or init file (wt. -Djboss.socket.binding.port-offset=200)
and to copy your standalone directory. This will spawn an additional
process. If you want to serve your Webapp within one process and only
one config file you will need to work with VHosts. This will require
modifications on you .war or .ear file to bind it to the corresponding
VHost.
The following steps are requeired:
1. Add your new VHost in your standalone.xml:
<server name="mynextwebapp-server" default-host="mynextwebapp-host">
<http-listener name="mynextwebapp-listener" socket-binding="mynextwebapp-manager"/>
<host name="mynextwebapp-host" alias="localhost">
<location name="/" handler="welcome-content"/>
<filter-ref name="server-header"/>
<filter-ref name="x-powered-by-header"/>
</host>
</server>
2. Add a socket-binding group to your new VHost in your standalone.xml:
<socket-binding name="mynextwebapp-manager" port="8081"/>
3. Now, it's time to modify your webapp (.war / .ear file):
Extract your .war / .ear file:
jar -xvf $file
Within your WEB-INF file modify your "jboss-web.xml":
<jboss-web>
<context-root>/
<virtual-host>mynextwebapp-host
<server-instance>mynextwebapp-serve
</jboss-web>
Rebuild your .war / .ear file:
jar -cfv $filename $content
Move the new .war / .ear file to wildflys autodeploy directory and
it'll deploy it under http://$serverip:8081/
And yes, there's another possibility with setting the webapp to a
different context-root. This is possible but you should make sure
that the served webapp will never use absolute pathes that won't
match anymore outside of the expected context-root path.
Extract your .war / .ear file:
jar -xvf $file
Within your WEB-INF file modify your "jboss-web.xml":
<jboss-web>
<context-root>/mynewcontextpath/
</jboss-web>
Create an empty "bean.xml" file.
Rebuild your .war / .ear file:
jar -cfv $filename $content
Move the new .war / .ear file to wildflys autodeploy directory and
it'll deploy it under http://$serverip:8080/mynewcontextpath/

- nginx servername string replace with binary patcher in python3
As already in this blogpost described it's also possible to patch the nginx
binary instead of recompiling the whole package just to modify the servertoken
like "Server: nginx/1.13.3". In fact that it's just possible to hide the
server version you will need to recompile or patch to get rid of it.
For patching the binary on Linux or FreeBSD you may take a little
Python3 script called nginx-srvname-patcher.py. Short reminder that
you may only use up to 5 chars to replace. You'll find it here:
#!/usr/bin/env python3
# 2017-08-11 nginx-srvname-patcher.py
# Florian Paul Hoberg
# This will patch your nginx binary file
# from Server: nginx to Server: B00B

# but limited to max. 5 chars

# Python Version: 3

- A stay at the "Linux Hotel" Villa Vogel Sang in Essen for Python & DevOP
For the last five workdays I've been sent to the Linux Hotel in Essen (Germany) to push
up my Python skills. Unfortunately I decided to not stay in the hotel and travelled by
train these days. This should become uncomfortable. But first let me tell you
something about Linux Hotel.
Linux Hotel is a synonym for (training) congresses in opensource related topics like
programming in C, Perl, Python; IT specialist related topics like LPIC certification,
LDAP and other software and even DevOp content like Ansible, Puppet, Chef, Foreman...
As I already told I decided to travel instead of staying there over night which
resulted in a heavy travel time just to see my girl daily. It was my first stay
there and I didn't know that it should become that impressive.
On our first day we got told on our breakfast that almost everything is included
for free. You do not need to worry about breakfast, lunch or dinner. There's also
ice-cream, cookies, cakes and candies the whole day. You get water, softdrinks like
Coca-Cola, selfmade Cola, ClubMate, coffee, tea, alcoholics like different sorts of
beer and whine the whole day for free. Yes - this is also included. This are things
that made it really easy to cool down and chill in the evening after your course -
if you stay in the hotel! For further socializing there're additional social events
like driving GoCart, going out to Essen, flying in the fly simulator. You're not
interested? Maybe you'll take a look for the gym, go for a run or relax in the sauna.
There're so many possibilities to make your stay as comfortable as possible. Next
time I'll stay there defnetly over night. This is really a great concept and it's
money worth instead of regular conferencing centers.
- Replace nginx server header without modifying headers or recompile of nginx
If you're fine with patching a binary file there's a possible way to hide or replace
the server header from nginx. Unfortunately it's also shown with turned off servertokens.
o As root stop any running nginx process and backup your nginx binary
o Open your nginx binary with an editor (e.g. vi `which nginx`)
o Search for pattern "Server: nginx" (should look like "^@^@^@^@^@^@^@^@^@^@Server: nginx^M")
o Replace nginx with a string limited by max. 5 chars (e.G. B00Bs)
o Start nginx again
o check for your new string (curl -I $IP |grep -i server)
