Today i got a call from a concerned individual who is alleging that trough the /usr/local/libexec/popper one can get into the system. Indicator is the syslog entry like this: Jul 20 11:23:33 ns popper[23620]: @ip250.white-plains3.ny.pub-ip.psi.net: -ERR POP EOF received ns popper[23623]: @ip250.white-plains3.ny.pub-ip.psi.net: -ERR Unknown command: "^P^P^P^P^P^P^P^P^P^P...many times ^P^P^P^P^P^P^P" Did anyone hear about this problem? What is the usual way for resolving these other than learning C and looking in the source code? thanks. Val.
