Users of our Sun 4/280 who have been remotely logging in via the Internet have occasionally been having problems establishing rlogin and telnet sessions. 'netstat' reports that tese sessions are ESTABLISHED and in a CLOSE_WAIT state. The users just see their rlogin command hang - they get no response from our Sun. The problem is intermittent on the Sun, and it doesn *not* happen on our Vax which sits on the same Ethernet and is configured like the Sun. Users get around the hanging sessions by doing an rlogin to the Vax, and then doing an rlogin from there to the Sun. The hanging session problem only happens when users are establishing the connection over the slow, sometimes unreliable Internet. (We are running SunOS 4.0.1 on the Sun, and Ultrix 3.0 on the Vax.) Any thoughts about what is causing this and how to fix it? Has anyone seen this problem before? David Gingold gingold@think.com Thinking Machines Corporation (617) 876-1111
