I have 6 5.3 and 3 5.4 for servers. The servers provide Samba/LDAP,
DHCP, Natting, IPSec (for vlan tunnels).
One, and only one server behaves very oddly. If I do a transfer to the
other BSD server there (LDAP Master and DNS), I get full wire speed:
tp> 150 Opening BINARY mode data connection for 'open.tar.bz2'.
ftp> 66%
|*****************************************************************************

ftp>
However when I issue a get command I get this:
ftp> get open.tar.bz2
local: open.tar.bz2 remote: open.tar.bz2
229 Entering Extended Passive Mode (|||61238|)
150 Opening BINARY mode data connection for 'open.tar.bz2' (557269784
bytes).

The data transfer rate is about 93.5% of these speeds for smb
transfers. No other server exhibits this behavior. I'm really puzzeled.
Here's an ifconfig -a:

Any suggestions as to wtf is up would be appreciated.
