I added today the task “Develop master plan for 2018” onto my todo-list for tomorrow… 1.5 weeks left until vacation \o/

Script to "centralize" checking for updates on FreeBSD

I have to administrate several FreeBSD-servers and I need to know which servers need updates. Eveen though I have a poudriere running, I also have a local ports-tree on the machines because they are either not using the poudriere because they are not migrated to it yet or there was some reason to have a locally compiled package. Now I want to know daily which servers need package-updates and if any server has packages that have known CVEs. Thus I update the index of the portstree daily with the following cronjob for root:

0 3 * * * portsnap -I cron updateI have several “classes” of servers, thus I want mails for every class of server. For each class I have a cronjob like this in my personal crontab (or you could put it on one of your servers): 0 6 * * 1-5 /usr/local/scripts/check_for_updates.sh class1The user needs to be able to log into each server with an ssh-key.


#!/bin/sh

TMPFILE=`mktemp`
case $1 in
class1)
SERVERS="server1 server2"
MAILADDRESS="my@mailaddress.foo"
;;
class2)
SERVERS="server3 server4 server5"
MAILADDRESS="my@mailaddress.foo"
;;
private)
SERVERS="privateserver1 privateserver2"
MAILADDRESS="myprivate@mailaddress.foo"
;;
esac

for i in $SERVERS; do
  echo "$i:" >> $TMPFILE
  update_count=`ssh $i "pkg version" | grep \< | wc -l`
  if [ $update_count -gt 0 ]; then
    echo "$i needs $update_count updates" >> $TMPFILE
    ssh $i "pkg version" | grep \< >> $TMPFILE
    echo "" >> $TMPFILE
    echo "" >> $TMPFILE
    ssh $i "pkg audit" >> $TMPFILE
  else
    echo "$i needs no updates" >> $TMPFILE
  fi
  echo "" >> $TMPFILE
  echo "" >> $TMPFILE
done

mail -s "$1 update status" $MAILADDRESS < $TMPFILE
rm $TMPFILE

mail -s "$1 update status" $MAILADDRESS < $TMPFILE
rm $TMPFILE

Yeah, the certificate from my university came and I have now officially a Magister. And in good old Magister-tradition I needed 20+ semesters ;)

And tonight I will fill out the application for starting a B.Sc.-program in Computer Science :)

Ich glaube ich habe gerade das erste Mal bewusst den Gender-* benutzt

Some very nifty ssh-tips in this article: blogs.perl.org/users/smy…

Ok, Bud Spencer und Terence Hill auf Italienisch zu sehen ist ungewohnt.

This looks interesting. Chatting just with a ssh-client

Well, FML. macOS 10.13, root-problem published. I set a root-password. I install Security 2017-001 which should fix the problem. I couldn’t even unlock with the set pw, thought I mistyped. I installed 10.13.1 and root works without a password again. Thanks Apple!

And his wive is actually the one who makes the career and he has to move with her and not the other way around. And she looks like a „normal“ woman not like some super sexed up doll. #diehard

Odd thing I find fascinating about Die Hard 1 & 2 is that the hero doesn’t get the some new girl in each movie but that he just tries to save his wive and wants to see his kids.

Why does it at least feel like there are so many tutorials, books and courses about shell-scripting that are just about bash but not about POSIX-shell scripting? With the latter one people can write portable scripts.

I read a biography about RMS and now I am really thinking about calling the OS GNU/Linux and not just Linux.

I hate computers…

Since kids can unlock their parents iPhone Xs with FaceID I can’t wait for the news coming out when the first kid emptied their parents credit card with in-app purchases.

I call this sunday “whiny sunday”

And now the migration assistant fucks up. Once upon a time Intold people to get Macs because “It just works” Apple what happened to you?

Ha, I have an „alias -s py=python“ in my zshrc That‘s why it is not working

What the hell? The shebang-works when called from bash but not in zsh? Oo

I am on Fedora 27 and a #!/usr/bin/env python3 gives me #python 2.7 according to sys.version

But when I run env python3 in the shell it shows me python 3.6

Why???

Woohoo, I have a booting system again. Let’s get this data from the backup again onto the system. Via USB 2……

An installation- or major upgrade fuck up makes you hate probably any operating system…

Now I try a clean install of High Sierra from a USB-stick. Let’s see if this works out :/
