I think I got this in the right section, but I'm not sure, so I would like to apologize in advance if you feel that this thread was categorized wrong.

Onto my question. In a few of the computer manuals I have read, there is a section about sending "forged" emails. I have a friend that I go to school with who is really into C programming but has been becoming more interested in network security lately. I loaned him one of my manuals "Hacking Exposed, 4th ed." and he came on MSN later that night asking me how to send forged e-mails. He said he couldn't figure it out, but the book told him about it.

I asked him what his problem was, and he said that he couldnt see a command line for the mail server. Apparently it was still the normal one for his C: drive. He is running on Windows XP. I asked him if he was using the GUI version of telnet or the command line version, and he said the command line one.

So I thought he needed to enable local echo. I wasnt sure how to do that on the command line telnet verion (the one that you use at the command prompt), so I told him to switch to the GUI version of telnet. Come to find out, that the GUI telnet isnt on his computer for some reason.

So I think he needs to enable the local echo from the command line. Is there anyone who knows how to do this? Also, is there anyone who knows what else could be wrong here?

I know this sounds noobish, but I honestly have no idea what is wrong here and have never encountered this problem.

EDIT: Sorry, but it seems the situation has changed a bit. He is somewhat blind, I suppose because the GUI telnet is there after all. He is able to enable the local echo, but is the odd part. He is telling me that once he enables local echo, it turns itself off. Maybe he is just trying to fry my brain, but I'm searching Google, and looking, but I can't figure this out! Help me please!
