I set up a test environment that I believe mirrors your= s: jail54# pwd /usr/home/glarkin jail54# ls -al testdir total 6 drwxr--r-- 2 root wheel 512 Apr 12 08:52 . drwxr-xr-x 5 glarkin glarkin 512 Apr 12 08:52 .. - -rw-r--r-- 1 root wheel 7 Apr 12 08:52 foo.txt jail54# # exit [glarkin@jail54 ~]$ cd testdir - -bash: cd: testdir: Permission denied [glarkin@jail54 ~]$ rm testdir/foo.txt rm: testdir/foo.txt: Permission denied [glarkin@jail54 ~]$ rm -rf testdir rm: testdir/foo.txt: Permission denied rm: testdir: Directory not empty My situation is slightly different than yours, since my jails are based on FreeBSD 6.4, instead of 7.x. As a first step to troubleshooting, please log in to your jail as your non-privileged user, run the following commands from its home directory, then post the permtest1.log and permtest2.log files somewhere that we can review them: truss -f -a -s 256 -o permtest1.log cd testdir truss -f -a -s 256 -o permtest2.log rm testdir/textfile.txt Also run the "df" and "mount" commands from the user's home directory inside the jail as well as from the same directory but outside of the jail context. Please post the output of those commands somewhere as well= . Thank you, Greg - -- Greg Larkin http://www.FreeBSD.org/ - The Power To Serve http://www.sourcehosting.net/ - Ready. Set.
