Q: I can log in fine, but when I try to check out a module of files from the CVS repository, I get this message: cvs [checkout aborted]: unrecognized auth response from localhost: cvs [pserver aborted]: descramble: unknown scrambling method

A: Check your CVSROOT variable setting. If there is a space character (' ') at the end of the variable value, that will cause this problem. To fix the problem, simply delete the extra space character.
