The unix rlogin and rsh commands permit users at remote trusted hosts to login to a local machine without specifying a password. It is possible for users at sites outside of York to masquerade as a trusted host and gain unauthorized access to systems that allow rlogin and rsh. Due to this problem and the rising number of computer security problems being reported everywhere in the Internet, machines managed by CCIS, which include all Mail servers, Synchronize servers and other timesharing servers at York, no longer accept rsh or rlogin connections from machines not belonging to the yorku.ca domain. If you are outside of the yorku.ca domain and need access to one of the above machines, please use telnet instead. We urge other system administrators at York to similarly restrict these services.
