We are running UCX v1.3A. (The "A" if for a patch recommended by CSC that was applied). Our hardware is 2 6210s running VMS 5.4, clustered. We have an elusive problem, where at times, and not always on the same node, when a user tries to access the VAXcluster with a telnet process from a CDCnet device, (TDI) the user gets the message "USER AUTHERIZATION FAILURE", after typing in the password. However the password is correct and not expired, or preexpired. Has any body any ideas about this situation? Thank you!

I have no idea on the "USER AUTHORIZATIOn FAILURE", but we also have trouble with CDCnet -> UCX1.3A Our problem: If somebody trys to connect from a CDCnet node to our VAX, the connection sets up, but he get no prompt, until he/she types in a Break-character. With some debugging, we found out, that the VAX doesn't respond immediately with a login prompt, if the other side doesn't support the Terminal Type option (as in CDCnet!). The prompt appears after some input, like a local terminal. That dolt CDCnet isn't able to send a character at this stage, only BREAK got it to send something! So there are two problems, one side is UCX which barfs on a missing Terminal Type Option, and CDCnet which isn't able to send at this stage.

Implementations of TELNET client based on the old Berkeley 4.2 code have a bug when binary mode is negotiated whereby they end the line with LF instead of CR. This causes your VMS username and password to never validate. This is not noticed on UNIX servers but for a few editors that run in raw mode and get confused by such clients. I've not experienced this problem with UCX, but that was because the broken Berkeley TELNETs have all been replaced around here long before UCX ever existed. /Kevin Carosso Innosoft

There is a patch available for this particular problem in UCX, which you should be able to get from your Customer Support Center (CSC). CDCnet I can't help you with. -- Spider Boardman spider@decvax.dec.com DEC OSG/CSSE ...!decvax!spider I don't speak for DEC, and vice versa.
