- DS5000/240, Ultrix 4.3.
-
- Under what circumstances should a rlogin return 'Host unknown', but
- telnet "Do the right thing?".
-
- A professor here is trying to get to inel for some work.
-
- schizo:~ % rlogin inel.gov
- inel.gov: Host is unreachable
-
- schizo:~ % telnet inel.gov
- Trying 134.20.1.1...
- Connected to inel.gov.
- [stuff deleted]
- SunOS UNIX (mica)
- login: Connection closed by foreign host.
-
- schizo:~ % rlogin inel.gov
- inel.gov: Host is unreachable
-
- schizo:~ % which rlogin
- /usr/ucb/rlogin
-
- schizo:~ % which telnet
- /usr/ucb/telnet
-
-
- Any suggestions appreciated.
-
- I can't think of anything on my end that would do such a thing, so maybe
- it's on their end. Perhaps a gateway that only allows connections on certain
- ports? ie, it blocks connections to 513, but allows connections to 23?
-
- Anybody heard of anything like this?
