socks programming

Hi people; i've been doing some soket programming; yet i got stuck; i was wondering if anybody could help me.
I can conect to hosts with the connetc( ) ; and recv() from them; yet; when i send() sth; the server does not respond to me.
I am trying to log into a POP server; i connect to it and recive the welcome page; yet when i send user Myuser; i get no response.
I think i'm missing the EOL; which would it be is '\n' fine?
myu script after recieveing the welcome screem go sotheing like:
send(sockfd, "user myuser'\n'" (in fact i use a cahr array here but it's the same), arraylength, 0);
is the EOL wrong; because i believe that my command is not being intepreted by the server.
Well I hope someone can help me...
thanks.

You didn't tell us, you're using what language in what platform. Anyway, POP3 daemon commands must be ended by CR (hex 0d, dec 13) LF (hex 0a, dec 10) sequence. Taken from RFC 1939:

Quote:

---

Commands in the POP3 consist of a case-insensitive keyword, possibly
followed by one or more arguments. All commands are terminated by a
CRLF pair. Keywords and arguments consist of printable ASCII
characters. Keywords and arguments are each separated by a single
SPACE character. Keywords are three or four characters long. Each
argument may be up to 40 characters long.

Try
send(sockfd, "user myuser\n", arraylength, 0);
not
send(sockfd, "user myuser'\n'", arraylength, 0);
don't quote the \n .

Just make sure the string ends with CRLF.

Peace always,

Thanks jdenny you are my saviour; it worked just fine when I added the string you told me i should cat at the end of my string...
