For _following_ symlink, permissions of symlink are not checked (at least not checked 'traditiomally' on unix -- I do not know about Linux.) On some systems for reading value of symlink if symlink is on NFS server, permissions of symlink are checked. I actually do not know is permissions of symlink checked (on various OSes) if sysmlink value is readed. / Kari Hurtta - To unsubscribe from this list: send the line "unsubscribe linux-newbie" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.linux-learn.org/faqs
