Web Server Demo Program

I think my real problem is in the untarring of the IMFS image.
I stepped through the function Untar_FromMemory().  This function 
takes an unsigned char pointer and a size value.  It does an offset
into the buffer and a string length compare with the string "ustar  "
and a length of 7.  This string compare is failing.  The string that 
I have in my buffer is just "ustar" instead of "ustar  ".

I am building using an OpenBSD system instead of the traditional 
Linux system.  Could this be my problem?  Or is this a bug in
the untar function?  I will try hacking the function to see if it
fixes my problem.

Also, when I build the application, the call to i386-rtems-objcopy 
to create the tarfile.o object file gives a warning that the output 
file cannot represent architecture UNKNOWN.  Is this warning normal?

I am trying to get the http demo up and running.  I am
using RTEMS snapshot 20021118 and network demos 20021018.

The http task (rtems_httpd_daemon) first calls to get the
host name (gethostname) and then calls to get the host
address (gethostbyname).  The gethostbyname() function
is failing.  I have added an entry into the rootfs/etc/hosts
file for my host name but when gethostbyname() does an
fopen() on the host file, the fopen call fails.  I have my

Any thoughts or hints on how I can get the http demo to 
work would be greatly appreciated.
