Without tracing through sub-processes, you won't be able to make sense of this 
log file. It just prints "forkpty() failed", which could have all sorts of 
different reasons.

GDB stracktrace not possible as shellinabox  has no debug symbol options i.e no 
./configure --enable-debug

It builds everything with "-g" by default. No need to set any options.

the default fedora rpms have no -g enabled.

http://gcc.gnu.org/onlinedocs/gcc/Debugging-Options.html helped 
 CFLAGS="-ggdb -g" ;./configure --prefix=/usr

but :
(gdb) run

I would recommend not building the RPM while debugging. Instead, just build the 
source tree that you can check out from Subversion.

./configure && make

should do the trick.

NO that don´t solve it.

(gdb)  run -d -n -v -t -u root
Starting program: /root/rpmbuild/BUILD/shellinabox-2.10/shellinaboxd -d -n -v 
-t -u root

ok i may think i looked at the wrong way.

the apache part is the issue.

mod_security stops shellinabox from working ;(
