Log files and disabled "who" command...

[root <root @ selket . van . wa . us>]

I have installed majordomo 1.93 on my Linux box (kernel version 1.2.9, 
perl 4.036) and everything works perfectly except that it won't write 
anything to the log file.  No errors, no "out of memory" explosions, 
nothing at all!

Here's the line from majordomo.cf that specifies the log file:

   $log = "/var/spool/majordomo/majordomo.log";

Here's the permissions for the path to /var/spool/majordomo/majordomo.log:

   drwxr-xr-x  13 root     root         1024 Jun 24 16:16 var/
   drwxr-xr-x  15 root     root         1024 Jun 19 04:20 spool/
   drwxrwxr-x   5 majordom majordom     1024 Jun 22 16:29 majordomo/
   -rw-rw-rw-   1 majordom majordom        0 Jun 22 15:05 majordomo.log

Ironically, I had it working just fine, and in my attempts to streamline 
the directory tree, I messed something up.  Does anyone see any glaring 
errors in the permissions or configuration?

And a second question... I am running a list for an organization that 
doesn't want anyone to be able to access the names of all the members of 
the list - not even the subscribers themselves!  Don't ask me to explain 
this particular bit of paranoia, because I don't quite understand it 
either.  I can only think of two solutions:

1)  Don't tell anyone about the "who" command, and hope that no one 
figures it out on their own.  :)

2)  Hack something to disable the "who" command.

The slick solution would be some way of disabling "who" for the 
particular list only, but honestly, I don't care if it's disabled 
totally.  Can anyone suggest a fix?  I'm not much of a perl programmer, 
and I'd rather not go fooling with it myself if someone can provide me 
with a patch.  :)

Thanks in advance, and have a great week!  Elena
