See that + on the end of the mode field? That means there are ACLs in affect; and my guess is one of the ACLs allows your uid to change to that directory even though the owner of the directory does not have the same permissions. > $ getfacl /c > # file: /c > # owner: ???????? > # group: ???????? > user::--- > group::--- > group:root:rwx > group:SYSTEM:rwx > group:Users:r-x Yep - just as I said. The actual uid/gid owner (which is probably being treated as -1 meaning your /etc/group and /etc/passwd are incomplete) is different than the 'root', 'SYSTEM', or 'Users' groups, all of which have an additional ACL allowing you to chdir into the directory. --=20 Eric Blake eblake AT redhat DOT com +1-919-301-3266 Libvirt virtualization library http://libvirt.org --------------enig056E41CF93BF0C4775E3177C Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Public key at http://people.redhat.com/eblake/eblake.gpg Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQEcBAEBCAAGBQJO1P9zAAoJEKeha0olJ0NqsV4IAJK8YZM0PjRmcVYu9gY1nWPd ULa3Mf/tZ3elQ0OVcS9E3ds9iVLnvK3CIFyLwx7SwKwStRUOgEQVyQaXqBLBeSEo UmDumZf5dEGCUNgcpmxAZbsZyPO9KIz2pGT1Frg07dQPHPOVMJxisy3GImueOzpU Cq6oH/djfGFAOEIJHFTo3GqmllAqy4cKTQ90EfKx9MtAOjjMmj94moLHg4l18yqb FYYnm9bJdEMZ0r+oAnlkkQferbbHgKBt2LsmDiUYkwtUNTbpV8OGlWxDvisLjow1 9Rh2Ea8AezZwmYFSk7D0k9caW0pO/kTCLOXipeiSce+V3EGvz7Xgf9V/Cz8kUGU= =hzzm -----END PGP SIGNATURE----- --------------enig056E41CF93BF0C4775E3177C--
