"ls" in a.out format as anonymous works fine.
"ls" in ELF format as anonymous fails - nothing comes out.
"ls" in a.out format as a non-anonymous user works fine.
"ls" in ELF format as a non-anonymous user works fine.

So this tells me (I think) that there is some sort of permissions
problem for some library when "ls" is invoked under
the anonymous FTP user. I can see no library with non-world
readable permissions.  So can anyone tell me:

(1) Anyone know what needs to be changed for this to work?

(2) What is the COMPLETE list of programs that get called
when you invoke the command "ls"

(3) How can I figure out the answer to (2) ?

Thanks in advance.

Ummmm, is the ELF version of ls compiled statically? In other words
when an anonymous user logs in a chroot() takes place and the copy of ls cannot
read the libraries needed to execute. so it dies.Just use the old version of ls.
if it werks that is.
