New page

Access Control Lists (ACLs) are a way of modifying file permissions in a way that is far more granular and flexible than [[Unix File Permission Primer|standard Unix file permissions]]. Unfortunately, ACLs are also more complex and can lead to very confusing situations if you're not careful. Consequently, we don't recommend using ACLs unless you find yourself in a situation that cannot work with the standard permission model. (When in doubt, you can always email [mailto:support@cs.jhu.edu support@cs.jhu.edu] for help with our systems.)

There are two types of ACLs in use on our systems. This page covers ''NFSv4'' ACLs, which are used on our [[Linux Clients on the CS Grad/Research Net|graduate Linux clients]]. For our [[Linux Clients on the CS Undergrad Net|undergrad Linux clients]], please see the page on [[POSIX Access Control Lists]].

Unfortunately, we haven't had time yet to fully document NFSv4 ACLs on our systems, especially since the standard permissions work in a vast majority of cases. The ACLs are accessed via the <tt>nfs4_getfacl</tt> and <tt>nfs4_setfacl</tt> programs; interested parties are encouraged to read their man pages.
