1) Run it on a 32-bit livecd
2) ldd(1)
Otherwise, look at the elftools (or something like that) package to get more info about the binary.
Don't you run all your systems with selinux?

Uh oh.  Finding an a.out in your /var/log/httpd doesn't instill

I have ~ 4k a.out there dated Oct 12, which unfortunately is just past
my logrotate cutoff now, so I can't check access.log (drat) without
hitting the (hard to hit) backups.

file a.out
a.out: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV),
dynamically linked (uses shared libs), not stripped

I fired up a live-cd linux with no disks or net attached to try to run
it (I put it on a usb stick). But when I do *the shell* returns ENOENT
and won't run. I tried ./a.out. I tried moving it to a fs that
shouldn't be mounted noexec. I tried strace a.out and strace ./a.out
and strace shows only the exec attempt and the error print and quit.

Huh? How can I get this thing to run?

Anyway to see what it is doing? Disassemble? It is not stripped, so
gdb? How can I step-run it from the start (ie nothing executes until I
step)?

What else to do with this file?

I'll see if I can dig up the access.log from that date and get more
details.
