I am noticing a lot of weird files appearing in my router and on my various filesystems. Files in weird places or files that have to do with security with a - sign after them.
If I do
ls -l /etc/shadow*, this is what I see.
-rw-r----- 1 root shadow 1163 Aug 9 15:48 shadow -rw------- 1 root root 1163 Aug 8 21:11 shadow-
Does that look normal? What is the 2nd shadow file used for?
