Constructor Details

Socks5BytestreamRequest

protected Socks5BytestreamRequest(Socks5BytestreamManager manager,
 Bytestream bytestreamRequest)

Creates a new Socks5BytestreamRequest.

Parameters:

manager - the SOCKS5 Bytestream manager

bytestreamRequest - the SOCKS5 Bytestream initialization packet

Method Details

getDefaultConnectFailureThreshold

public static int getDefaultConnectFailureThreshold()

Returns the default connection failure threshold.

Returns:

the default connection failure threshold.

Since:

4.4.0

See Also:

• setConnectFailureThreshold(int)

setDefaultConnectFailureThreshold

public static void setDefaultConnectFailureThreshold(int defaultConnectFailureThreshold)

Sets the default connection failure threshold.

Parameters:

defaultConnectFailureThreshold - the default connection failure threshold.

Since:

4.4.0

See Also:

• setConnectFailureThreshold(int)

getConnectFailureThreshold

public int getConnectFailureThreshold()

Returns the number of connection failures it takes for a particular SOCKS5 proxy to be blacklisted. When a proxy is blacklisted no more connection attempts will be made to it for a period of 2 hours. Default is 2.

Returns:

the number of connection failures it takes for a particular SOCKS5 proxy to be blacklisted

setConnectFailureThreshold

public void setConnectFailureThreshold(int connectFailureThreshold)

Sets the number of connection failures it takes for a particular SOCKS5 proxy to be blacklisted. When a proxy is blacklisted no more connection attempts will be made to it for a period of 2 hours. Default is 2.

Setting the connection failure threshold to zero disables the blacklisting.

Parameters:

connectFailureThreshold - the number of connection failures it takes for a particular SOCKS5 proxy to be blacklisted

getTotalConnectTimeout

public int getTotalConnectTimeout()

Returns the maximum timeout to connect to SOCKS5 proxies. Default is 10000ms.

When accepting a SOCKS5 Bytestream request Smack tries to connect to all SOCKS5 proxies given by the initiator until a connection is established. This timeout divided by the number of SOCKS5 proxies determines the timeout for every connection attempt.

You can set the minimum timeout for establishing a connection to one SOCKS5 proxy by invoking setMinimumConnectTimeout(int).

Returns:

the maximum timeout to connect to SOCKS5 proxies

setTotalConnectTimeout

public void setTotalConnectTimeout(int totalConnectTimeout)

Sets the maximum timeout to connect to SOCKS5 proxies. Default is 10000ms.

When accepting a SOCKS5 Bytestream request Smack tries to connect to all SOCKS5 proxies given by the initiator until a connection is established. This timeout divided by the number of SOCKS5 proxies determines the timeout for every connection attempt.

You can set the minimum timeout for establishing a connection to one SOCKS5 proxy by invoking setMinimumConnectTimeout(int).

Parameters:

totalConnectTimeout - the maximum timeout to connect to SOCKS5 proxies

getMinimumConnectTimeout

public int getMinimumConnectTimeout()

Returns the timeout to connect to one SOCKS5 proxy while accepting the SOCKS5 Bytestream request. Default is 2000ms.

Returns:

the timeout to connect to one SOCKS5 proxy

setMinimumConnectTimeout

public void setMinimumConnectTimeout(int minimumConnectTimeout)

Sets the timeout to connect to one SOCKS5 proxy while accepting the SOCKS5 Bytestream request. Default is 2000ms.

Parameters:

minimumConnectTimeout - the timeout to connect to one SOCKS5 proxy

getFrom

public Jid getFrom()

Returns the sender of the SOCKS5 Bytestream initialization request.

Specified by:

getFrom in interface BytestreamRequest

Returns:

the sender of the SOCKS5 Bytestream initialization request.

getSessionID

public String getSessionID()

Returns the session ID of the SOCKS5 Bytestream initialization request.

Specified by:

getSessionID in interface BytestreamRequest

Returns:

the session ID of the SOCKS5 Bytestream initialization request.

accept

public Socks5BytestreamSession accept()
                               throws InterruptedException,
XMPPException.XMPPErrorException,
Socks5Exception.CouldNotConnectToAnyProvidedSocks5Host,
SmackException.NotConnectedException,
Socks5Exception.NoSocks5StreamHostsProvided

Accepts the SOCKS5 Bytestream initialization request and returns the socket to send/receive data.

Before accepting the SOCKS5 Bytestream request you can set timeouts by invoking setTotalConnectTimeout(int) and setMinimumConnectTimeout(int).

Specified by:

accept in interface BytestreamRequest

Returns:

the socket to send/receive data

Throws:

InterruptedException - if the current thread was interrupted while waiting

XMPPException.XMPPErrorException - if there was an XMPP error returned.

SmackException.NotConnectedException - if the XMPP connection is not connected.

Socks5Exception.CouldNotConnectToAnyProvidedSocks5Host - if no connection to any provided stream host could be established

Socks5Exception.NoSocks5StreamHostsProvided - if no stream host was provided.

reject

public void reject()
            throws SmackException.NotConnectedException,
InterruptedException

Rejects the SOCKS5 Bytestream request by sending a reject error to the initiator.

Specified by:

reject in interface BytestreamRequest

Throws:

SmackException.NotConnectedException - if the XMPP connection is not connected.

InterruptedException - if the calling thread was interrupted.
