Re: disabling remote xdm logins
ipfwadm -I -a reject -P udp -S 0.0.0.0/0 -W eth0 -D 209.109.31.9 177 This only works for Linux, and only if IP Firewalling is enabled in the kernel, right? I need to be able to prevent xdm logins using the standard xdm stuff on Linux and possibly some non-Linux systems. Based on the xdm documentation, it does seem like I should be able to disable remote xdm logins using the Xaccess file. Unfortunately, I can't seem to configure xdm properly so that it will prevent remote xdm logins. (btw, it's not a broadcast -- the client sends a UDP broadcast.) Yeah? Heh, okay...my bad. :) So what actually happens? Is the xdm on the local machine listening for xdm requests?

Could someone please explain how I can configure my debian system to stop accepting xdm logins from remote machines? Look at the file /etc/X11/xdm/Xaccess, it is full of comments that describe the file's function and format: # The first form tells xdm which displays to respond to itself. # The second form tells xdm to forward indirect queries from hosts matching # the specified pattern to the indicated list of hosts. # The third form tells xdm to handle indirect queries using the chooser; # the chooser is directed to send its own queries out via the broadcast # address and display the results on the terminal. # The fourth form is similar to the third, except instead of using the # broadcast address, it sends DirectQuerys to each of the hosts in the list You are probably mostly interested in the first form. On my machine, where I haven't changed it, the first form entry reads: * #any host can get a login window If you change the * to localhost then I guess that would stop xdm from responding to any display (xserver) but the one on your console.
