| I run the speech check fucntion at 0.2 seconds. Call me crazy... but I do. In a small mod I dont see any performance hit from this. Maybe (and a I do mean maybe... I am not sure) in a large mod with lots of people talking at once I may see the mod heartbeat take 7 or 8 seconds to come around again instead of 6. |

Ok, I've got a question. The readme says that the plugin has to run with root privs so it can bind to the network interface. Can that be done by just making the nwnx_speech.so file SUID root? Because I am not keen on the idea of having to run the nwserver application as root just to make this work....
Anyone know?

I have no idea. You could try that out. The plugin needs rights to be able to access the network interfaces. If you can set those on another way, please let me know so I can update the documentation  . |

Naw, no love there.  I tried setting nwn_speech.so and even nwnx2.so as SUID root, but all I got for my effort was a core dump. I'm not real happy at the prospect of running my nwserver application as root, but I suppose it's not that much of a security risk - it's not like someone could crash the server process and be sitting in a shell.
So, I was running this in a test directory to see how things would work. Started it up, and got:
$ sudo ./nwrun

Now this was before I ran the "Talus Speech Setup" module. Here, it's just a copy of my main game module (which has not yet had the talus .erf file imported into it), but it's running in my test server directory, which listens on port 5125, not the standard 5121 of the main game server. What's with the "seems to be hanging here " message?
Now then, I start up the setup module:
$ sudo ./nwrun

Again, what's with the "seems to be hanging here " message? What does it think is hanging?
Some other questions: I typed "*help*" as the readme in the talus system archive says to do. It doesn't say what is supposed to happen when you type it. But from within the module where I typed it, nothing happened. What is it supposed to do, and do you have any suggestions as to why it didn't do whatever? This was inside the speech setup module.
Also, why (how?? ) does it listen to what *both* the main and test servers are listening to? Is there a way to restrict it to just listen to the server application that it's running on? Something like a "port=5125" option that can be put in the [Speech] section of nwnx2.ini?
And what about the database tables being used? Do they just grow forever until your database sucks up all available disk space, or does this thing automatically get rid of old entries?
Are there scripting commands provided by this system that lets you log the output to your main nwnserverLog1.txt file? And which would then let you send output to a DM's chat window (a'la the way the DMFI listening stuff outputs what NPCs hear)?
I suspect that as I delve further into this, I'll figure out the answers to some of these. But in case I won't, I figured I'd better ask now.
Thanks!

| Though it's delving a bit on the linux heavy side I found this: http://killa.net/infosec/acls/ would probably be a right pain to get working espically since the latest 2.4 kernel is a few revisions on from the latest patch on the page, but there might be other ACL systems which allow non-root access to packet sockets. |

Does anyone have a listing of what [Speech] options can go into the nwnx2.ini file? In particular, I'd sure like to know how to set the "servername" name that's going to be in that particular column of the database row....

If you let the server run with root privileges, I would suggest using a chrooted environment, or even user mode linux.

Heh.. that was just a debug line which I forgot to remove  . I will do that soon, when I will port the new non-database functionality to the linux speech module.
Everything seems to run normal as it receives the talke strings from people. So, you are on the good way! The Talus NWScripts take care of the database. They fetch a line from the database and immediately removes it. Then it will process the line and does what requested.
You should run Talus demo module which can create the database entries neccessary and then import the ERF in your own module and place a placeable (see documentation) somewhere in your module. Finally set up the onload (I think  ) script. The servername is just written to the database in case of a multi server environment. |

Um, what was just a debug line?

I *do* have a multi server environment. Go back and read my earlier message. I have a test server on the machine, as well as the main server. They live in two separate directories. But somehow, while running the Talus Speech Setup module (which is the demo module) on the test server (which listens on port 5125), I noticed in the nwn_speech.txt log file that it was also capturing text going through the main server, which listens on port 5121 (the regular port). Like I said, I'd really like it if there was some kind of port= parameter for the [Speech] section of nwnx2.ini, so that I can tell it to just listen to the one server port. As to the "servername" thing, here's the problem: The demo Speech Setup module is NOT getting anything from the database and deleting it. The reason is this: The listener is writing to the database with a blank "servername" field/column. In the lds_speech_db script, it does a:
string sServer=GetModuleName();
which in the demo module is "Talus Speech Setup". As a result, its call to:
"select {blah} from nwn_speech where servername = '"+sServer+"'"
doesn't find anything that matches.
This is why I'm asking if there's a way to tell the nwnx_speech.so plugin what to put in that last "servername" column when it does its insert into the table. I tried doing a:
servername=Talus Speech Setup
and a:
module=Talus Speech Setup
in the [Speech] section of nwnx2.ini just as a wild guess, but they didn't do anything. So if there's a way to do this, could you please tell me what it is? And if there isn't currently, could you add it?
BTW, is there any kind of documentation that lists what the various types of messages are? One of the things it store is a numeric message type, which ends up being 1, 4, 14, etc. It would be nice to know what those codes mean.
Thanks.

The "seems to be hanging here .. " line was used for debugging.
The server name is what is listed in the Server window. If you don't fill in a name, there won't appear a name in the database (I am not sure if you ment that you gave the server the "Talus .." name). If you have filled in a Server Name, then something is obviously wrong
And no, there currently is no option for disabling one server yet in the sources as the original code didn't have it either. I might be able to add it but that will happen then when I will port the new changes of the windows version to Linux which will happen at earliest next week. |

Oh, ok.

Um, what Server window are you talking about? Not sure I'm following you here. I start my Linux stand alone server from a shell prompt (command line). There is no "window" for me to fill in with anything. The nwnx_speech.so plugin is doing INSERTs into the database with a "servername" field that is blank. But the module is doing a SELECT from that database, and it has a line which says:
string sServer=GetModuleName();
If you edit module properties, you will see on the Basic tab an entry called Name. In the case of the Talus Speech Setup demo module, that value is set to "Talus Speech Setup." So when the module does its SELECT, it's doing it with a servername value of "Talus Speech Setup."
Now obviously, the work around would be to change that above line in the module to:
string sServer="";
And in fact I've already verified that it works. Now that's all find and well and good, but if I'm running my main server module, and then start up the test server with a new version of that module to do some testing before making it live on the main server, nwnx_speech.so is going to be listening to both of them and recording to the database. Problem is, many times when I do this kind of testing, I just use the same database. If I were using two different databases, it wouldn't matter because nwnx2.so in each server would be writting to two different databases, and there'd be no crossover problems. However, if they're both pointing to the same database, then you have both of the plugins dumping to the same database, that both modules are looking at. I'm afraid that at this point you cold end up with the test server module grabbing something that was stored there, and now the main server doesn't see it, and you've got players wondering why their emotes, etc., aren't working right.
Thus, my desire for an option in nwnx2.ini in the [Speech] section which lets me set what the "servername" is going to be that that instance of nwnx_speech.so is going to be writing to the database.
I.E., in server/main/nwnx2.ini, under [Speech], have "servername=Main Server" and in server/test/nwnx2.ini have "servername=Test Server" - then the plugin uses that when writing to the database. The test and main modules can then both share the same database and they won't interfere with each other.
I hope that more clearly explains what my concern is.

If by that you mean no ability to tell it which port to listen to, that's ok. It would be nice to be able to do that, but it's not criticial. However, I do consider the ability to set what it's going to use as a "servername" column when it does its INSERT to be more critical, for the reasons I mention above. Any chance that can be added at some point?

What do you give as servername parameter? In the nwnstartup.sh is this option listed and you should have a valid name for it. If you don't supply this option with a valid name the GetServerName will ofcourse return an empty string as there is no server name.

This is a bad workaround in your case as you (soon) have 2 servers listening. With an empty string the wrong server can fetch the message from the database which is not expected. Thats where the server name comes for. Then the scripts will only fetch rows mentioned for that server.
But I will see if I can add such a functionality to the plugin some time. I am now to busy with studying, so I will probably have some time next week. |

Here's how I start the module:

#!/bin/bash
#
mod="CHAINMAIL_Beta"
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/mysql
export LD_PRELOAD=./nwnx2.so
./nwserver -module "$mod" "$@"
unset LD_PRELOAD
|
As you can see, I'm setting the -module parameter where it starts the server. So I don't know why the plugin is drawing a blank....

Uh, yea. I thought I mentioned that. This being my concern. Now, I'm pretty sure that if I'm running two databases, one for each module, I don't think it will be a problem. However, there are many times when I'm testing a new version of a module and just using the same database is more convenient. That's what concerns me.
