I am assuming that the tail end is a source IP address. If this is the case, you could:-
  • Consider disabling the echo port.
  • Investigate why the source is polling you.
  • Remove xinetd entirely and force users to use SSH
To disable echo, have a look in /etc/xinetd.d/echo-dgram There is a statement that you can set disable = yes Restart xinetd to make this effective:-
Code:
service xinetd restart

The default is disabled, so I wonder what the requirement was.

Forcing SSH is always a little contentious though. If you need a telnet type client, there is of course putty, but we've gone for SecureCRT from Van Dyke Technologies and it's pretty good. You do pay for it though.




I hope that this helps,

XINETD.LOG(5)							File Formats Manual						     XINETD.LOG(5)

NAME
xinetd.log - xinetd service log format DESCRIPTION
A service configuration may specify various degrees of logging when attempts are made to access the service. When logging for a service is enabled, xinetd will generate one-line log entries which have the following format (all entries have a timestamp as a prefix): entry: service-id data The data depends on the entry. Possible entry types include: START generated when a server is started EXIT generated when a server exits FAIL generated when it is not possible to start a server USERID generated if the USERID log option is used. NOID generated if the USERID log option is used, and the IDONLY service flag is used, and the remote end does not identify who is trying to access the service. In the following, the information enclosed in brackets appears if the appropriate log option is used. A START entry has the format: START: service-id [pid=%d] [from=%d.%d.%d.%d] An EXIT entry has the format: EXIT: service-id [type=%d] [pid=%d] [duration=%d(sec)] type can be either status or signal. The number is either the exit status or the signal that caused process termination. A FAIL entry has the format: FAIL: service-id reason [from=%d.%d.%d.%d] Possible reasons are: fork a certain number of consecutive fork attempts failed (this number is a configurable parameter) time the time check failed address the address check failed service_limit the allowed number of server instances for this service would be exceeded process_limit a limit on the number of forked processes was specified and it would be exceeded A DATA entry has the format: DATA: service-id data The data logged depends on the service. login remote_user=%s local_user=%s tty=%s exec remote_user=%s verify=status command=%s Possible status values: ok the password was correct failed the password was incorrect baduser no such user shell remote_user=%s local_user=%s command=%s finger received string or EMPTY-LINE A USERID entry has the format: USERID: service-id text The text is the response of the identification daemon at the remote end excluding the port numbers (which are included in the response). A NOID entry has the format: NOID: service-id IP-address reason SEE ALSO
