RE: [Chrootssh-users] chroot() not happening here either

New_root
new_root

C is case sensitive - you might want to check that you have got the right
capitalizationsin the code.  But actulaly they are just warnings, what
happens when the code is compiled - does it run?

Subject: [Chrootssh-users] chroot() not happening here either


I'm using OpenBSD 3.1 and 3.3.  I've got the tarball
openssh-3.6.1p1-chroot.tar.gz

When it's compiling I notice in the warnings:
session.c: In function Do_setusercontext':
session.c:1217: warning: unused variable New_root'
session.c:1216: warning: unused variable User_dir'

It seems to me from looking at the code that do_setusercontext() is where
the actual chroot() happens, based on whether /./ is found in the variable
new_root, but that's only if CHROOT is defined.  CHROOT is defined,
unconditionally, just after the #includes.

The lines 1217 and 1216 where the warnings originate are inside an #ifdef
CHROOT, as is the chroot() call itself, based on the condition:
if(strncmp(new_root, "/./", 3) == 0) {

It seems like new_root is kind of a critical variable to get warnings about
it being unused.

I haven't done any programming under OpenBSD at all, only some C under
FreeBSD, and C isn't my forte anyway, being more of a Pascal/Delphi type.
This just looks odd.

The chroot just doesn't happen, but the sshd itself seems to be working, and
according to this I'm running the patched version I expect to be:
  leto:alan {102} ssh -V
  OpenSSH_3.6.1p1, SSH protocols 1.5/2.0, OpenSSL 0x0090602f
