my pdflatex setup

Since I can't seem to purge my machine from tex things (even "apt-get purge" gets into trouble because of missing files), I'm using a script to run pdflatex remotely:

scp temp.tex gusl@stat.ubc.ca:thesis
ssh gusl@stat.ubc.ca 'cd thesis; pdflatex temp.tex'
scp gusl@stat.ubc.ca:thesis/temp.pdf .

It's kinda ridiculous... for one, I need to type my password 3 times every time. Is there a way to be automatically authenticated, or have the password sent automatically?
