Easy - the right thing for me. But: I can't find a tool like ollydbg on linux. gdb, ddd and edb don't seem to work. Do you have a little clue for that?

r2s2: try to get your hands on "ida pro" for linux.
or there is a free tool called "HT Editor" which is also quite powerful. Pretty tame compared to IDA pro but still I prefer it in many ways (more stable etc).

Use HTE together with scripting for GDB and you're set for life :)

r2s2: Also, a hint, there were some anti-debug techniques used in this crackme. Might be why you can't use GDB right away...

Very easy crackme.. Use IDAPro to get the password and test the crackme in Linux/Unix

I submitted my solution a few days ago..

The IDA Pro Evaluation worked fine for this task. Quite easy although quite fun.

I am a complete beginner to reverse engineering and this was not easy for me! But I have to say I had a lot of fun trying to solve this. Thank you!

Thanks for the crackme. Because gdb was my debugger of choice this crackme was maybe a little bit more difficult than "very easy"...

Hello: I've never done this before; it took me about three hours to get the password. I still don't understand why GDB acted the way it did. Anti-debug techniques? --cyber111970

Four verifications? Why? Four patchings are not harder than one patching...
The hardest thing in this one is to find necessary function, i used "search for strings" option in disassembler.
