Here is another strange thing. When I run lsmod I get this output:

Module                  Size  Used by

e100                   30656  -

On my other firewalls I get more in the Used by column. More like this:

ipt_limit                984   6  (autoclean)
ipt_LOG                 3448   1  (autoclean)

mii                     2544   0  [eepro100]
(this is a screen shot from a similar server but running 2.4 kernel)

Does this have anything to do with my file transfer problem?
