This article covers the various errors and reporting message that can occur when SNIP<\/strong><\/span> is operating in a closed<\/strong> <\/span>mode such that every new user (every NTRIP Client) must present a valid account and a password in order to log in.<\/p>\n

If SNIP<\/strong><\/span> is operating in a open<\/strong><\/span> mode, the messages described here will not apply.\u00a0 Under open mode connections all a user (an NTRIP Client) needs to do is request a mountPt that matches to those in the current Caster table. A similar article dealing with the general debugging of client connections (operating in the open mode) can be found here<\/a>.<\/p>\n

It should also be noted that MountPt strings are always<\/span> case sensitive.<\/p>\n

Background Article<\/h3>\n

Adding new users is covered in general terms in this article<\/a>.\u00a0\u00a0 This article may be of use in understanding how to operate the various console filters<\/a> which SNIP<\/strong> <\/span>provides.\u00a0 Effective filtering is of great benefit when trying to debug a problem connection in the presence of many other server events in the log.<\/p>\n

Closing the SNIP Caster<\/h3>\n

The critical check box\u00a0Allow Anonymous access for Users<\/strong> which is used to enable or disable the open\/closed mode of the SNIP<\/strong> <\/span>Caster is described in this<\/a> article.<\/p>\n

Watching User Connections as they Occur<\/h3>\n

The console log can be used to view each NTRIP Client dialog as it occurs.\u00a0 The critical check box to enable this is to set Display New User Connection Details<\/strong> which found on the Caster and Clients<\/a> tab.\u00a0 Be sure to also set the Log threshold to “minor” and enable client message types in order to see these details.\u00a0 When checked, after each connection is processed, a report of its outcome is presented in the console log. Additional analysis details are provided when the Caster is closed and the connection attempt failed.<\/p>\n

A Typical NTRIP Client connection<\/h3>\n

Looks like the below when all goes well. In these examples we presume that we have created an account set up with the credentials of:\u00a0\u00a0 user:password<\/em> \u00a0 (all lower case).\u00a0 When the user:password pair sequence is sent, they are encoded in a Base64<\/a> format.\u00a0 The NTRIP Client will connect to a mountPt which is called:\u00a0 MOUNTPT<\/p>\n

[C56]: Client [#C56] appears to an NTRIP Client connecting with:\r\n[C56]: An NTRIP Client sent: ======================\r\n[C56]: \r\nGET \/MOUNTPT HTTP\/1.0\r\nUser-Agent: NTRIP RTKLIB\/2.4.2\r\nAuthorization: Basic VXNlcjE6bm9uZQ==\r\n[C56]: ======================\r\n[MOUNTPT]: Mount Pt [ MOUNTPT ] is a match - allow connection IF credentials match a user entry.\r\n[MOUNTPT]: Credentials for user accepted.\r\n[MOUNTPT]: Client #C56 [69.75.31.227:61916] Connected to MOUNTPT at 05:45:33 PM (local)\r\n<\/pre>\n
When a problem occurs, the analysis details explain what was found and what it likely means (corrective action).\u00a0 Resolving the problem may mean a change in what the NTRIP Client device sends, or it may mean that you (as the SNIP<\/strong><\/span> operator) must adjust the table entry for this user.<\/p>\n
