Telnet failed to localhost.
Hi,
I am trying telnet to localhost 514. But the connection is refusing.
Port does not appear in netstat. IP table service is also off.

maxdb_ping
MAXDB_PING(3) 1 MAXDB_PING(3)
maxdb_ping - Pings a server connection, or tries to reconnect if the connection has gone down
Procedural style
SYNOPSIS
bool maxdb_ping (resource $link)
DESCRIPTION
Object oriented style
bool maxdb::ping (void )
Checks whether the connection to the server is working. If it has gone down, and global option maxdb.reconnect is enabled an automatic
reconnection is attempted.
This function can be used by clients that remain idle for a long while, to check whether the server has closed the connection and recon-
nect if necessary.
RETURN VALUES
Returns TRUE on success or FALSE on failure.
EXAMPLES
Example #1
Object oriented style
<?php
$maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s
", maxdb_connect_error());
exit();
}
/* check if server is alive */
if ($maxdb->ping()) {
printf ("Our connection is ok!
");
} else {
printf ("Error: %s
", $maxdb->error);
}
/* close connection */
$maxdb->close();
?>
Example #2
Procedural style
<?php
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s
", maxdb_connect_error());
exit();
}
/* check if server is alive */
if (maxdb_ping($link)) {
printf ("Our connection is ok!
");
} else {
printf ("Error: %s
", maxdb_error($link));
}
/* close connection */
maxdb_close($link);
?>
The above example will output something similar to:
Our connection is ok!
