You can use rtmpdump on linux to download videos from a page that uses rtmpe / flash to display the videos. If you want to, you can also run an ssh tunnel. This could be used with benefit if you want to watch videos from a web site that you can't …

There's a couple of places (naturally). It's easy to be fooled and think: "anybody can type man man". But in all fairness, you need to figure out which man page to look into, or what command to run and sometimes it's just a blank. In RHEL there is /usr/share …

I just received the EXAM results. This was on Sunday at around 1500 Finnish time. About three days after I took the exam, these guys must be working on the weekend to check the results! Result: 300/300!

Wow, there's lots of it in there. Some of it is about networking and a lot about individual services. I haven't actually planned to go get the exam soon, but I think just going through these objectives will make me better at Linux. Anyway, if I pass the RHCE, that …

Before that we were playing with partitioning, making swap, encrypting with cryptsetup and LUKS. Also very interesting. After we learned …

I wrote in the preparation that there were no 'set up ftp/www service'. What do you think we did today in the course? Set up vsftpd and httpd :) Ssh hardening, set up vnc server, configure firewall via gui, ntp setup. Stuff like that. It's getting closer! I believe tomorrow …
