Very Computer

    I just set up a client computer under Red Hat 5.2 via an
NFS installation, which went perfectly.  When I try to send and recieve
data via an ftp session from my server to my linux client computer, data
is transferred extremely slowly.   This problem occurs with NFS and ftp
sessions.  A packet of data is sent from the server to the client every
two minutes.  This problem never occurs from my Windows computer to my
server.   Telnet sessions from my newely setup linux computer work
perfectly. When I do an ifconfig on the client computer the ethernet
device shows that there are errors.  I think that the an error is
created every time a packet is sent.  On the server there are no errors,
but there are collisions.  This problem only ocurrs locally.  If I try
to retrieve data from an ftp session from a remote computer the speeds
are perfect just like the telnet session.  What should I try to do?
