Sunday January 7, 2018What I still don’t understand about Meltdown and Spectre is, how targeted the attacks can be. Can I get only some random memory, can I dump everything, can I aim for example for a certain process (like the password manager of a user in a different vm) etc…

Sunday December 31, 2017„A Burglar‘s Guide to the City“ is not really what I expected and there are often passages where I thought that they could have been shortened. So far 3 out of 5 (page 157 of 296)
Update: Finished it now. Pretty good book after all. 4 out of 5 , sometimes a bit too long. I would have hoped that there is more about architecture and more details in terms of weaknesses. And I think about getting some lockpicks again.

Saturday December 30, 2017Uncharted Worlds seem to be the better choice for our group than Traveller. Simpler rules, more or less the same setting. And simple rules are king when you play only once a month imho.

Wednesday December 27, 2017A friend went into an electronic discounter & got a laptop recommended with 4GB RAM and a slow HDD. The moment windows update does stuff it gets slow as hell & she wonders what the problem could be. Dear discounters people really think they get good advice from your sales people.

Wednesday December 27, 2017Tomorrow I‘ll receive a new Bulletjournal and Frixion gel pens. Let‘s see if I can get into paper again in 2018. For studying I believe in paper more anyways for taking notes and exam preparation. Laptops are great for writing papers but not for getting stuff into your head.

Monday December 25, 2017As I have written before I will soon start studying CS part-time. Any recommendations for getting through math (besides visiting every session and doing all the homework - that’s how I got through all those math (or heavy on math) courses in economics at least)? Any good books?

Monday December 25, 2017How does it come that the bios of my shadowrun-characters get darker & grittier the older I get? In the past it was the cool hacker, the war hero who used his skills in a more profitable way. Today it is the hardened criminal, abused as a kid, trying to survive in a world of pain

Script to "centralize" checking for updates on FreeBSD
Sunday December 10, 2017I 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
