Permission problem in message command with guest ftp user

[Joel Hammer]

Boy, how wrong I was. There is a permissions problem, but not what I dreamt
of, with kedit %s as the message command.
Here is the message as it arrives on the client computer in /tmp:
-rw-------   1 ftp  ftp   1517 Nov  8 19:26 msg.20m8g9 
Yes, that's right, the client, who is not user ftp, cannot read this
message.
root can read it, but of course, he needs to be added to xhosts before he
can run kedit.
I tried to change the permission of kedit:
-rwsr-sr-x   1 root root  210589 Apr 3  1999 /opt/kde/bin/kedit            
but my regular user still can't read the message file.
That is puzzling, at least to me.
I guess this is a good reason not to use guest logons, at least for linux
clients.
I suppose a more careful choice of the guest account might get around this
problem.
