I've seen this happen on our systems when somebody left a background process running on one of the pty's. If you're unlucky enough that the next free pty is the one with the process, telnet and rlogin will both successfully connect, but get no further. Killing the process, or modifying it to carefully close all files and dissociate itself from the terminal, will cure it. This could be why it's suddenly appeared, and is unpredictable.
