Please forgive me if I'm going too basic.  I noticed that this hasn't been
brought up yet, but by default, both Telnet and FTP servers are typically
serviced by inetd (or xinetd), and not started via the init.d scripts.

Check your /etc/inetd.conf file (or in the /etc/xinetd.d directory).  Both
inetd (older) and xinetd (newer) listen for requests for different services.
When the request is received, it starts up the respective daemon.

A side note, though.  You should really consider using SSH instead of telnet
(or FTP, for that matter).  OpenSSH (which is almost always installed by
default) runs as a daemon (typically, /etc/init.d/ssh start or
/etc/init.d/sshd start).  To remotely connect to the host, type "ssh
username@host".  To FTP files to or from the host, type "sftp
username@host".  Or, if you know the file's location, and you just want to
issue a remote copy command (to or from), type "scp <file>
username@host:<path>"

Hope that helps.
