problem while running HOSTAPD v. 0.2.4

[JOHANN FABIO SARASTY PANTOJA]

Hi all.
I am having a problem while trying to run HOSTAPD version 0.2.4.
I am running HOSTAP on linux red hat v. 2.4.20-8.

The next log appear:

[root at boxlinux hostapd-0.2.4]# ./hostapd hostapd.conf
Configuration file: hostapd.conf
ioctl(SIOCGIFINDEX): No such device
Host AP driver initialization failed.
ioctl[PRISM2_IOCTL_HOSTAPD]: Operation not supported
Could not remove generic information element from interface eth1
ioctl[SIOCGIFFLAGS]: No such device
[root at boxlinux hostapd-0.2.4]#

I checked in the mailing list and try some recomended solutions but the result is the same.
Any idea what is happening?
Thanks in advance.

Johann
