Description :
Internal xinetd simple services (not very useful one):
- chargen
Chargen is short for Character Generator and is a service that generates
random characters either in one UDP packet containing a random number (between
0 and 512) of characters, or a TCP session. The UDP Chargen server looks for a
UDP packet on port 19 and responds with the random character packet.
With TCP Chargen, the server sends as a continuous stream of TCP packets once
a connection is made, and until the session closes. The data is thrown away.
Chargen is used to find the cause for dropped packets. It uses TCP/UDP port
19. An infiltrator can create a DoS attack by spoofing an IP address and
causing two devices to send random traffic to each other.
RFC 864 describes the Chargen service.
- daytime
The Daytime protocol is another testing tool and uses port 13 for both UDP and
TCP versions. On receipt of a datagram to port 13, the server in the UDP
version, sends the current date and time in ASCII format in a datagram. The
TCP version, on receipt of a datagram to port 13, and once the connection is
established, sends the date and time in ASCII format and closes the
connection.
RFC 867 describes the Daytime service.
- echo
Echo uses UDP and TCP port 7 and is used as a debgging tool to send any
datagrams received from a source, back to that source. The risk with this is
that someone who has access to the network can overload devices via the Echo
service amounting to a DoS attack.
RFC 862 describes the Echo service.
