Generally, the user defaults to the soft limit and can use ulimit to
set values up to the hard limit. Tim's suggestion bumps the soft
limit up to the hard limit, so all the user could do with ulimit is
move the per-user limit back down.

With Tim's response to this -- I'm curious (so that we get correct
information on the FAQ) -- is the /etc/security/limit.conf method a
system-wide way of setting these values, and "ulimit -l" a per-user
way of setting it?
That doesn't sound quite right to me -- I'm assuming that a user
can't "ulimit -l X" where X is larger than the numbers in /etc/
security/limits.conf -- can someone confirm if this is Right?
Also, is each user's default "ulimit -l" value the same as what is
in /etc/security/limits.conf? (what's the difference between "hard"
and "soft" limits?)

Hi Daryl,
Sounds like this might be a ulimit issue, what do you get when you
run ulimit -l?

Strange thing is that it works properly when I run as root. A
permissions
problem on my part? My devices look like:
