[BLUG] Some webhosts

[Mark Krenz]

  For comparison, Suso has comporable services and maybe a third of the
number of users and the load averages about 1.  Less now that I've
distributed the load a bit better.  It never goes above 5 unless
something is wrong.  From what I've seen on Dreamhost, A load between 8
and 200 is the norm.  Since normal users can't see the whole process
table, its hard to tell what is going on.  The system itself was a bit
sluggish and transfers took forever.  The way they do things is just
odd.  I would never NFS mount that many partitions.  Its better to
create more servers to put your users on instead of trying to put them
all on one server.

  Ok, you got me into it now.  Their security was horrible, the home
directories wheren't world readable, but they were world executable, so
if you knew any of the subdirectories, you could get into someone's web
directory where everything was world readable and perhaps world
writeable.  Finding out someone's web directories where easy too because
the xferlog was world readable, which meant you could see what everyone
was transfering to their accounts.  And they say that their servers are
secure because they are protected by ninjas.  What a joke.  A sure sign
that the people there haven't got a clue.

  I've gotten tired of seeing thing kind of thing on webhosts so I've
started a page on my new personal website/wiki for it:

  http://suso.suso.org/xulu/Web_hosting_providers_with_poor_security

  A note to people using Internet Explorer, I haven't fixed the
mediawiki stylesheet yet to work properly.  I'm trying to make it look
like my current site (http://suso.suso.org/)
