RHEL WS 4.0, ifconfig eth? down not working


On Redhat WS 4.0
I'm having a real problem with both eth0 and eth1.
ifconfig eth0 down and ifconfig eth1 down do not work.
Code:
# uname -a
Linux entropy 2.6.9-34.0.1.EL #1 Wed May 17 16:44:57 EDT 2006 i686 athlon i386 GNU/Linux

# ifconfig eth0 down
# dmesg
0000:01:06.0: tulip_stop_rxtx() failed
0000:01:06.0: tulip_stop_rxtx() failed
eth0: Setting half-duplex based on MII#1 link partner capability of 0021.
eth0: no IPv6 routers present

# ifconfig eth1 down
# dmesg
eth1: duplicate address detected!
lo is the only interface that can be brought up/down by ifconfig.
Note I don't think the half-duplex is a problem because my 10BT hub.
I have no idea why eth1 is saying duplicate addresses?
Code:
# ifconfig

Hello randyding,

May be you do have duplicate addresses on your network:-


Check out if you have this address on other machines too:-

eth1: 192.168.77.1


eth0: 192.168.1.2 (Just in case)


Post if you find something
