- So far, I've come across two bugs in DEC TCP/IP Services (TPS?) for
- OpenVMS 2.0. First of all, binary telnet mode does not work properly. A
- carriage-return is interpretted literally as a CR, instead of a combination of
- CR and LF (line-feed), and control characters are interpretted as line
- terminators. This behavior was observed telnetting to a host running Ultrix
- 4.2A. For example, it's necessary to use CTRL/J at the Ultrix login prompt,
- rather than a CR (CTRL/M). It can also be observed by telnetting back to the
- same system. Enter a string at the DCL prompt and press CTRL/U; with line-
- editing, the line should be erased, but instead it's entered as a command.
-
- Here's an interesting one:

-
- In particular, look at what happened to the User_name: field. What's so in-
- teresting is that our rlogin service is defined with the rejection message
- "UCX RLOGIN connection refused"; if we replace "refused" with "rejected" we
- experience a similar corruption of the User_name: field for the rlogin service
- entry. Note that this corruption only seems to be in memory; adding the
- /PERMANENT qualifier to the SHOW SERVICE command reveals nothing out of the
- ordinary.
-
- Finally, has anyone figured out how to enable the binary (8-bit) option
- for outbound rlogin?
