Please ignore. I'm trying to see if the list mangles mails sometimes... . Johnny --

I read the hecnet list using VMS Mail and I therefore get to see all the headers in their gorey detail. I've never seen any mail from the list arrive with base64 encoding. I've had a quick look through the headers for all the hecnet mail for the last few days. I find some mails have Content-transfer-encoding: 7BIT and others have Content-transfer-encoding: 8BIT (including some that are not from Hans). Just one mail (the HTML section of a mail from Jordi Guillaumes i Pons) had Content-transfer-encoding: quoted-printable and none at all had Content-transfer-encoding: base64. In particular, the ones from Hans do not arrive here with Content-transfer-encoding: base64 I can't see anything special about the mails from Hans that would be causing those and only those to result in difficulties on a 7bit only system. Perhaps a mail transfer agent processing mail for the system experiencing the problem is making incorrect assumptions about some of the mails going through it and somewhat arbitrarily deciding to convert some of them to base64? (I do see some headers such as X-Spam-Status: containing references to base64 but this should have no bearing on how the mail is processed.) No. Some mails from Hans was encoded in Base64. If you didn't see that, then there is something going on at your side to hide it. But I think Hans solved this.

DECnet User Mode Router - Encapsulation Formats

It is going to be a while before I am ready to debug seriously against an existing tunnel, but if you could make one available in any case that would be great so I can start to see what things look like.

Ciscos can encapsulate DECnet within either GRE or L2TP. -Dave -- Dave McGuire, AK4HZ New Kensington, PA I hope GRE and L2TP aren't too complex. It *looks* like GRE can be transported over UDP. L2TP looks a bit more complex, but I have skimmed the Wikipedia page for all of 15 seconds so I may have missed something. Regards Rob
