I've Bcc:'ed the list, per your permission, to at least capture the results for posterity. I'm glad that things now work for you. Your understanding of the RFC is not a fault; the negotiation hack for stack identification of the client machine is not well documented anywhere; it's "black magic" that you have to find a practitioner to pass the secret on to you, or find some older source code that has it noted in the comments from someone who has also has the problem, fixed it, and commented their code as a result. Hopefully now that this is documented in the -hackers list archive, if someone else has the problem, a search engine will find this message for them. If anyone else is having a problem with a telnet client that is unable to talk well to FreeBSD (I think there are two Linux-based terminal server products that have this problem, since I know I've used one of them ;-)), consider this a clue to send to the manufacturer. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
