"su -m" will be a solution only if "/bin/bash" is a valid shell and the caller is root : "The invoked shell is your login shell, and no directory changes are made. As a security precaution, if the target user's shell is a non-standard shell (as defined by getusershell(3)) and the caller's real uid is non-zero, su will fail." But apparently, Brandon can't login anymore with "root" account because "/bin/bash" doesn't exist (so isn't a valid shell...). --=20 Jean-Pierre FORCIOLI OpenPGP: 1024D/CF173713 Cyber Networks http://www.cyber-networks.fr/ Tl : +33 (0)1 42 04 95 89 Fax : +33 (0)1 42 04 95 87 --=-oLL4nkW6vSiHXSKQChCW Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (FreeBSD) iD8DBQBA7jFQaKwq8c8XNxMRAivrAJ4kIX759foMlTISJePcQ5wccee+iACgui6t 4ET+DgqT/rzCJ07J/vR1R2Y= =Zh71 -----END PGP SIGNATURE----- --=-oLL4nkW6vSiHXSKQChCW--
