On windows, there is an application called Advanced Onion Router (or, AdvTOR) which lets you choose your tor exit nodes, and it lists them all out. This is great, because some exit nodes have bandwidths that are thousands of times faster then that of others. On Linux, however, we don't have AdvTOR. There is a similar program called SelekTOR, but I found it unstable and really it didn't work because it would say it was connected to a certain node when it really wasn't.
A list of tor nodes is here: https://torstatus.blutmagie.de/
And for the sake of this question let's say I wanted my exit node to be Orion:
orion.enn.lu [94.242.246.24]
From what I have researched, you can change your exit node manually in the torrc file. If there are other ways, please let me know, I just need to know how to manually set my exit node to , for example, Orion listed above.
EDIT: I don't necessarily need to do it manually. I'm on Ubuntu 15. if there are any programs with GUI's that would make this easier, let me know.
Appreciate in advance anyone helping or looking at this. ;)
