Ubuntu/John the Ripper
From charlesreid1
Installing John the Ripper on Ubuntu:
Contents
Obtain Source
I went with 1.8.0.6 jumbo from the John the Ripper account on Github.
Build
Just build it.
$ cd JohnTheRipper*/src
$ ./configure --prefix=/path/to/john
$ make
$ make install
I recommend setitng the prefix for John the Ripper if you have it installed as part of your OS, package manager, or just have another John the Ripper on your system somewhere.
WPA
This is covered over at the John the Ripper/WPA page.
Other Stuffs
This pretty much worked as expected, without modification. I had a problem with John "not recognizing hashes" in password file. But this turned out to be because the password file I was pointing it to was EMPTY.
Oops.
Once that was fixed, everything worked great.
