Lightbulb Checking concurrent SSHD connections

Hi Guys

i am facing an issue when SSH connections are overflowing on my server, i get connections from thousands of servers, out of which few does not close them after sending a file.

i want to pull some information about concurrent ssh connections

i used "netstat -an | grep 22"

i need to know what time that particular connection was made with my server. Can someone pls suggest me if i can get that information

Second thing is, can i enable the log somewhere which can gather all these information, so that i can check the results for couple of days. If yes, what should i be doing for that,

Thanks in advance
Smilie

MongoClient::close - Closes this connection

SYNOPSIS
public bool MongoClient::close ([boolean|string $connection]) DESCRIPTION
The MongoClient.close(3) method forcefully closes a connection to the database, even if persistent connections are being used. You should never have to do this under normal circumstances. PARAMETERS
o $connection - If connection is not given, or FALSE then connection that would be selected for writes would be closed. In a single-node config- uration, that is then the whole connection, but if you are connected to a replica set, close() will only close the connection to the primary server. If connection is TRUE then all connections as known by the connection manager will be closed. This can include connections that are not referenced in the connection string used to create the object that you are calling close on. If connection is a string argument, then it will only close the connection identified by this hash. Hashes are identifiers for a con- nection and can be obtained by calling MongoClient.getConnections(3). RETURN VALUES
Returns if the connection was successfully closed. EXAMPLES
Example #1 MongoClient.close(3) example This example demonstrates how to selectively close all connections for secondaries only. <?php // Connect to a replicaset $a = new MongoClient("mongodb://whisky:13000/?replicaset=seta"); $connections = $a->getConnections(); foreach ( $connections as $con ) { // Loop over all the connections, and when the type is "SECONDARY" // we close the connection if ( $con['connection']['connection_type_desc'] == "SECONDARY" ) { echo "Closing '{$con['hash']}': "; $closed = $a->close( $con['hash'] ); echo $closed ? "ok" : "failed", " "; } } ?> The above example will output: Closing 'whisky:13001;X;4948': ok CHANGELOG
+--------+---------------------------------------------------+ |Version | | | | | | | Description | | | | +--------+---------------------------------------------------+ | 1.3.0 | | | | | | | The $connection parameter to this function was | | | added in 1.3.0. Before that, only the write con- | | | nection would be closed by this method. | | | | | 1.2.0 | | | | | | | Before version 1.2.0 the driver would not use | | | persistent connections by default, and all con- | | | nections would be closed as soon as a MongoDB | | | connection went out if scope. Since version 1.2.0 | | | this is no longer the case and it is a bad idea | | | to call close as you might end up overloading the | | | server with connections under high load. | | | | +--------+---------------------------------------------------+ SEE ALSO
