  +--socks.server.Ident

public class Ident

extends java.lang.Object

Class Ident provides means to obtain user name of the owner of the socket on remote machine, providing remote machine runs identd daemon.

To use it:

Socket s = ss.accept();
Ident id = new Ident(s);
if(id.successful) goUseUser(id.userName);
else handleIdentError(id.errorCode,id.errorMessage)

Field Summary

static int	connectionTimeout Maximum amount of time we should wait before dropping the connection to identd server.Setting it to 0 implies infinit timeout.
static int	ERR_NO_CONNECT Identd on port 113 can't be contacted
static int	ERR_PROTOCOL Identd daemon responded with ERROR, in this case errorMessage contains the string explanation, as send by the daemon.
static int	ERR_PROTOCOL_INCORRECT When parsing server response protocol error happened.
static int	ERR_TIMEOUT Connection timed out
int	errorCode Error code
java.lang.String	errorMessage Error Message can be null.
java.lang.String	hostType Host type as returned by daemon, can be null, if error happened
boolean	successful If this is true then userName and hostType contain valid values.
java.lang.String	userName User name as returned by the identd daemon, or null, if it failed

Constructor Summary

Ident(java.net.Socket s)
Constructor tries to connect to Identd daemon on the host of the given socket, and retrieve user name of the owner of given socket connection on remote machine.

ERR_TIMEOUT

public static final int ERR_TIMEOUT

Connection timed out

ERR_PROTOCOL

public static final int ERR_PROTOCOL

Identd daemon responded with ERROR, in this case errorMessage contains the string explanation, as send by the daemon.

ERR_PROTOCOL_INCORRECT

Constructor Detail

Ident

public Ident(java.net.Socket s)

Constructor tries to connect to Identd daemon on the host of the given socket, and retrieve user name of the owner of given socket connection on remote machine. After constructor returns public fields are initialised to whatever the server returned.

If user name was successfully retrieved successful is set to true, and userName and hostType are set to whatever server returned. If however for some reason user name was not obtained, successful is set to false and errorCode contains the code explaining the reason of failure, and errorMessage contains human readable explanation.

Constructor may block, for a while.

Parameters:

s - Socket whose ownership on remote end should be obtained.
