• zmodem transfers failing

    From Deon George@3:633/509 to Vince Coen on Sat Sep 22 23:27:34 2018

    Hello Vince!

    21 Sep 18 15:38, you wrote to me:

    I did get it working, I changed it from fido:// to telnet:// and it
    worked a treat. I was suspecting that MBSE was not calculating the
    checksum - possibly because fido:// over TCP is by definition
    reliable? Anyway, using EMSI over telnet was the thing.

    You have lost me on this one :(
    Do not understand the usage of fido - telnet etc but I do not have
    telnet installed any more only use ssh - Security issues with telnet
    as it has no security.

    I dont have telnet installed - it is an alternative to BINKD. Binkd sessions are over 24554. fido:// ones are 60177 and the telnet:// ones are 60179. I think the later two are modem emulated IP connections(?) - IE: I needed EMSI to the old board, and it expires the "connector" to transmit some special chars to destingish between a mailer calling and human (wanting to go into the BBS)...

    Now this I can relate to as I get bad packets from my up link almost weekly.

    I just delete them.

    Let me know the results of your examinations as it might relate.

    I'm guessing, that these were "dummy packets" from my old BBS - there was a zmodem option enabled to send a dummy zmodem transfer. Those dummy packets were zero bytes in size - and they stopped once I turned that option off...
