Telnet has the concept of the Network Virtual Terminal, for which it sends control codes in-band. The escape codes you are seeing are those control codes. Think of it as kinda like curses for the NVT. For details see: http://www.scit.wlv.ac.uk/~jphb/comms/telnet.html Skip On Thursday 20 April 2006 09:37, gamgamus () yahoo com 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?
