The AS400 does use EBCDIC. -----Original Message----- From: Art Cooper [mailto:acooper () pop innerwall com] Sent: Thursday, April 20, 2006 7:12 PM To: gamgamus () yahoo com; pen-test () securityfocus com Subject: Re: AS400 telnet traffic 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... On 20 Apr 2006 16:37:33 -0000, gamgamus wrote
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.
