Remove PDF passwords in Ubuntu

Have you ever bought a book in PDF format, only to receive it with the annoying password protection popup? You know, the ones that come with digital downloads and/or "free" copies that escort payed hard copies, where you need to type your e-mail every single time you open them. Hey, I'm all for protecting your content and such, but this just feels like I'd get more value if I downloaded a pirated copy!

Cisco IOS update, enable ethernet

Having actually managed to connect to the router via console, I thought I'd be capable of doing some simple configuration tests with the router. Well, that turned out to only be half true, since there still were some kinks with the way Cisco has decided to plumb its products. I set the following tasks to do for today:

  • Update IOS to the latest version I happened to have ( 12.4-15.T8 )
  • Make the router available via Ethernet telnet

Ubuntu, Minicom & Cisco router console connection

Got a nice Cisco 857w to play around with yesterday :) Before you get into any misconceptions let me tell you that I've never before made my own configuration in a Cisco router, but I really (really!) want to learn about it ( hey, stop snickering! ).

So... first things first - wipe out the router config, I thought, and start from scratch. I managed to do THAT part pretty easily, however, as any knowing person will tell you, that leaves all ethernet ports down... so here comes the console cable to the rescue! If you can actually make it to work :P

Make SSH faster

Well, at least the login part. For some (very) weird reason, some distros think that everyone is part of some huge, corporate environment -- thus making Kerberos and GSSAPI logins the default methods.
Is there a problem with that ? Well, not directly - you only need to wait until SSH can understand that login just ain't gonna happen that way, and fallback to the good' old username/password asking. The real problem is that it can...take...AGES!
