Yes. Which is the best approach depends upon whether the connections
are related in any way.
For the case where the connections are all independent (e.g.
telnet/FTP/HTTP servers), using fork() is preferable.
For the case where the connections are related (e.g. a MUD or
conferencing system), then either use select() or threads.

You shouldn't need to use both select() and fork(). If you use fork(),
then each process only deals with a single connection, so there is no
need to use select().

You are probably including the line terminator. The expression
strlen("nemanuel\r\n")
will return 10.
