I'm currently installing the listener; just a minor: the init script nwnspeech is missing 
EDIT: Ok, another problem: The NWNX log says SPEECH is registered, with nwnx_speech.txt holding all those verbs. But the logfile of nwnspeechd (nwnspeech.txt) is non-existent, and no nwnspeechd in process table. I tracked it down to a problem with setsid(). Keep up the good work.
Details: running Debian linux 2.6.8,
| Code: | root@debian:# ldd /usr/bin/nwnspeechd
libpthread.so.0 => /lib/tls/libpthread.so.0 (0x4002a000)
libpcap.so.0.8 => /usr/lib/libpcap.so.0.8 (0x40039000)
libmysqlclient.so.12 => /usr/lib/libmysqlclient.so.12 (0x4005f000)
libstdc++.so.5 => /usr/lib/libstdc++.so.5 (0x4009d000)

Ah, I couldn't sleep till I figured this one out. I simply made a little fix, and it works nicely now (in a first test):
In nwnspeech/daemon/nwnspeechd.cpp search the lines | Code: | pid_t sid = setsid();
if (sid < 0) {
exit (EXIT_FAILURE);
} |
and replace it with | Code: | | pid_t sid = setsid(); |
(setsid() returns -1 when the process is already a process group leader and has nothing to do)

Erk; so it is (missing). And thanks for the info on setsid, I'll include it in the next update. I wonder why it works correctly for me.
As an aside, I also found a very minor issue, in which the "POP" commands getting received are getting logged at the "INFO" level, making a lot of spam at the default logging level.
Here's the init script, you can copy into /etc/init.d/nwnspeech, and should then be able to chkconfig --add

I'm not sure, but I think this line will not work, $app is not initialized. However, with debian linux this script won't work anyway. I adopted it for Debian users. Place it into /etc/init.d/ | Code: | #!/bin/bash

As a side note: You may not want to call the init script nwnspeechd, or it will be killed like the daemon when you try to stop the daemon (because of the same name; all processes called nwnspeechd get killed). Call it nwnspeech 
BTW. what's that setsid() for anyway? sid doesn't get used anywhere else.

Correct, my copy is saved as "nwnspeech". Just rereading some of that init script, and your observation about [ -f $app] is obviously correct. Once again, I'm left wondering how it works on my systems.
Also, some comments near the top of the file (regarding options and settings) that are a carryover from the first linux version I had done, which took those options as command line parameters. (The -f $app was a carryover from an earlier version as well).
| Quote: | | BTW. what's that setsid() for anyway |
Found reference to that for use in creating daemon procs ... that was /supposed/ to be in the chunk of code that was commented out for my own later research into how to best write daemons.
... bear with me here, I'm a recovering Windows programmer learning linux ins and outs by trial and error. Not that this excuses these particular issues, but I can try and hide behind it for a little while at least |

I haven't had a chance to download and look at it yet, but am I correct in guessing that there's some kind of .conf file for the listener program that tells it what database, table, username, pw, etc., to use?

Yes. /etc/nwnspeech.conf, included. The default settings run in 'plugin' mode and don't create a database setting.
seem to have found a bug, too tired to think it through tonight, but doing a netstat after the server has been running for a while, I see 8-10 open streams to the /tmp/nwnspeech, all from nwnspeechd, same pid.
I do know that the connection was restarted a couple of times (there's a 10 or 100 ms timeout on the socket to prevent from hanging the game), I'm wondering if that's the cause of this. I'll have to dig into it tomorrow (this is mostly just a note to self so I don't forget ) |

I messed around with it and after some trouble on a RHEL4 system with it not finding the libmysqlclient (added -L /usr/lib/mysql to fix to Makefile) I got it to compile.
I can launch it and it just runs then immedately dies without saying anything else. No log, no socket, nothing.
I will look into why this is, might have to do with new 2.6 kernel or something?

Try removing the lines 851 to 854 of file daemon/nwnspeechd.cpp | Code: | pid_t sid = setsid();
if (sid < 0) {
exit(EXIT_FAILURE);
} |
Then recompile the daemon.

Following all the instructions here, I got this all up and running. The socket exists, and the "/o" reports as tells back to my PC.
In nwnx_speech.txt I've got a slew of errors reporting:
Attempting to connect to server.Connecting to speech server.
Connected to speech server.
ERROR: Server closed connection with RC 11. Will attempt to reestablish on the next call.
over and over again.
Also, *help* and /o help don't seem to report anything.
This is on RHEL4. |

Hi,
The [ -f $app ] test returns true on your system (or any system using bash for that matter), because $app isn't initialized and you didn't enclose the variable in quotes. Essentially, the expression evaluates to this:
[ -f ]
which will always return true. (Try it if you don't believe me =))
The proper way to do this is to quote the variable like this:
[ -f "$app" ]
then it will do what you think it should.
It works like this because uninitialized variables do not evaluate to null when evaluated if they aren't quoted. Why that is, I don't know.
Pretty much, you probably want to enclose any variables in double quotes if you are going to use them in a test to protect yourself from this kind of thing.

Yes, I've got it working pretty well, although I did see a nwserver lockup this evening after pulling the lever to grant my test character access to the extended commands.
I have seen the stale connections like you saw. They are definitely due to nwserver exiting. For some reason the connection to the socket stays open.
I will probably look at this in depth tomorrow.
Otherwise, it's working great!

Have there been any new developments on this? Any updates, etc.? Any stability problems reported?
Am getting to the point where I'd like to try this out, since I *really* don't like running nwserver as root....
