## Documents for inetd

Code [inet001e]

One or the other of the two listed files are unavailable. These files are required for the checks to proceed. This either indicates an incorrect configuration, or that a port to this machine has not been completed.

Code [inet002f]

The indicated service is assigned to the wrong port. This indicates either a misconfiguration in the services database, or a possible sign of an intrusion. This should be checked and corrected. If it is not apparent why it is like this, the system should be checked for other signs of intrusion.

Code [inet003w]

The indicated port number is assigned to another service. This indicates either a misconfiguration in the services database, or a possible sign of an intrusion. This should be checked and corrected. If it is not apparent why it is like this, the system should be checked for other signs of intrusion.

Code [inet004i]

The indicated service has been added to the services database as distributed. These are normal output, but you should be familiar with what is there, and note any changes.

Code [inet005w]

'inetd' is using the indicated binary for the listed service instead of what is normally expected there. Unexpected differences should be checked, and if anything unusual is found, the system should be checked for other signs of intrusion.

Code [inet006f]

The 'rexd' service is very insecure and should never be enabled. It should be disabled immediately by editing the inetd.conf file and removing the 'rexd' entry, and sending a HUP signal to the 'inetd' process.

For AIX systems, CERT Advisory CA-92:05 is applicable.

Code [inet007w]

'inetd' is using the indicated executable for a port other than what would normally be expected for this port. This may indicate a backdoor into the system and should be checked. If anything unusual is found, the system should be checked for other signs of intrusion.

Code [inet008]

The owner of the indicated executable is not 'root'. The owner of the executable should be root in order to reduce the possibility of it being altered or replaced.

Code [inet009]

The indicated executable is group writable, world writable or both. The executable should be owned by root and writable only by the owner. This reduces the possibility of it being altered or replaced.

Code [inet010i]

The program listed in the `inetd' configuration file does not exist or is not executable.

Code [inet011i]

The listed entry is a local addition to the `inetd.conf' file. This should be checked to see if it is a valid addition. If it is not, it should be removed.

Code [inet012w]

sysstat enabled

Code [inet013w]

netstat enabled

Code [inet014i]

The listed entry was protected by tcp wrappers by the default installation and is currently protected this way too. This is a good thing!

Code [inet015i]

The listed entry has been modified in order for it to be protected by using tcp wrappers. This has been changed from default installation (which did not provide it) but is probably a better setup.

Code [inet016f]

The listed entry was protected by tcp wrappers by the systema but has, for some unknown reason, changed to no longer be protected by them. Make sure that the service is secured since, if not using tcp wrappers, access control for it might be disabled.
