Hardest box I’ve been doing so far. Finally rooted that b*tch. Thanks a lot to @snowscan for making this, I learned a TON of new stuff.
User is easy and there is plenty of hints already in this thread ; as for root, there are quite a few gotchas on the way to root.txt.
Some things that messed with me for some time : if you change the .conf of a service, be sure to write it and/or to restart the associated service so it gets accounted. Also, interface changes can be your friend. And last, but not least : be polite, say HELO.
Thanks a lot to @f1ndm3 and @Downloading for confirming I was on the right path, as well as @Xess , with whom it was quite fun to work
