I’ve got 4 web pages running from my account. In doing some checking after this last flurry of hacks, I found that the log directories had permissions drw-r–r-- and that I, as owner, could not cd into the directory.
Normally x on a directory allows you to search through the directory. E.g
if foo has permissions r-------x and bar has permission r-----r-- then Other can read foo/bar, and can cd to foo/bar.
read permissions however gave you both read the directory, and cd to the directory.
Is this something new?
