Did it ever occur to you that GNU Queue is something like a trojan horse? Here is why:
Have your admin install queued as root on any server so that you can submit jobs there from your computer (i.e. have your computer added to the qhostfile). Now log into your own computer as root and use a command like:
queue -h server -- passwd
and the server is yours!
This works because the queued daemon has root privileges on the server. When a job is transmitted, only the user id (not the password) is used by queued on the server to run the command. Thus it is possible to execute root commands on the server without the need for the root password.
This means never start queued as root!
An instant sollution would be to run queued as an unprivileged user. In that case, you could also ommit the no_root_squash option for the nfs-exported directory.
Another way would be to by default dissallow queued to execute commands as root.
