|Title:||Check for Quote of the Day (qotd) Service (TCP)|
|Summary:||The Quote of the Day (qotd) service is running on this host.|
The Quote of the Day (qotd) service is running on this host.
A server listens for TCP connections on TCP port 17.
Once a connection is established a short message is sent out the connection (and any
data received is thrown away). The service closes the connection after sending the quote.
An easy attack is 'pingpong' which IP spoofs a packet between
two machines running qotd. This will cause them to spew characters at each other, slowing the
machines down and saturating the network.
- Under Unix systems, comment out the 'qotd' line
in /etc/inetd.conf and restart the inetd process
- Under Windows systems, set the following registry keys to 0 :
Then launch cmd.exe and type :
net stop simptcp
net start simptcp
To restart the service.
