Mounting MTP

I had to mount MTP FS for my Android phone. Following these instructions worked:

Essentially, it involves installing the simple-mtpfs package, putting an appropriate rules file in /etc/udev/rules.d, and reloading the rules, and then mounting with simple-mtpfs.

Using Google Authenticator for sshd password login on Linux

Here are the standard instructions:

I wanted to enter the password and OTP together instead separately for two prompts. This is important for things like connecting to NX through a login password.

On Fedora, I followed the instruction of adding the forward_pass option and it worked like a charm. I had to make sure I had a new-enough version of the RPM, though. v0.3 didn't seem to support the option.
