If I remember correctly - the AS400 may be encoding EBCDIC and that's why it
looks like gobbedly-gook.. I could be wrong, but I think that's it...

Hello,
I have captured some AS400 telnet traffic with tcpdump on port tcp 23.
It seems to be encoded in some way, because I only can see a few
initial cleartext words, like: IBMRSEED, KBDTYPE, CODEPAGE, IBM-
3477. The following stream of words are unreadable with encoding or chiper.
When I see the dump with Ethereal, the decoded data are like:
\000\r\022\240\000\000\004 and goes on...
Does anyone known how to decode this capture to get the cleartext form?
Thanks in advance,
Gam.
