I tried to change them back as best I could by comparing them to an older directory, but some things are still not right. Trying to log in, via either console or ssh  as anyone other than root. Ssh gets:

Console complains about the /home/user directory not being there (though it is and the permissions look normal), says it's logging in with slash instead, then says "/bin/tcsh: no such file or directory", though /bin/tcsh is there and permissions look fine. I'm attaching a screenshot of the message log that shows up on console logins.

/home is normally a link to /usr/home

lrwxr-xr-x root wheel home -> usr/home
drwxr-xr-x root wheel usr

is that what you have?

if it was done with -R then best bet is to restore from backup.


# mkdir foo
# ln -s foo boo
# ls -l
total 2
lrwxr-xr-x  1 root  wheel    3 Nov 14 15:46 boo -> foo
drwxr-xr-x  2 root  wheel  512 Nov 14 15:46 foo

# chmod 600 *
# ls -l
total 2
lrwxr-xr-x  1 root  wheel    3 Nov 14 15:46 boo -> foo
drw-------  2 root  wheel  512 Nov 14 15:46 foo

# chmod 755 *
# ls -l
total 2
lrwxr-xr-x  1 root  wheel    3 Nov 14 15:46 boo -> foo
drwxr-xr-x  2 root  wheel  512 Nov 14 15:46 foo
