The first type of error occurs when I run the listener on my Windows 10 using a terminal (powershell). The listener (remixd) starts OK then when I go to connect to the browser session I get the following:

Fix Remixd EPERM error
npm uninstall -g remixd
npm install -g #remix-project/remixd --force

UPD: Problem solved after switching TURN server from reciprocate-turn-server 1.9.7 to coturn 4.4.2.1
For the life of me I cannot figure out how spammers are sendmail mail through my server with relaying off. I'm running Sendmail 8.14.7 on Slackware Linux 14.1. The spammers have not figured out a user's password and are therefore logging in first via SASL with AUTH LOGIN or I would see that in the log.
Heres an example from my logs, a spammer/bot from 182.234.55.47, off the top of someones head what would allow this? Any IP randomly in the world can do this, yet when I try it sendmail says "relaying denied...". I could not be more lost. I firewall them but it happens again an hour later from a different IP.

Is it possible to write in the couchdb server log (the one defined by default.ini or local.ini in [log]) from a couchapp? (But from somewhere else than a view)
If that's not possible, maybe there's a workaround which would allow to log successful or unsuccessful authentication attemps in the couchdb server log? I'd like to process this server side and would like to avoid logging all httpd activity and grepping for user logging patterns, which doesn't seem to be easy or pretty...
Cheers,
Jun
A year later I find that it was in fact possible to log from views (or lists or any Javascript Design Doc functions) using the log() function: http://docs.couchdb.org/en/1.6.1/query-server/javascript.html#log
log(message)
Log a message to the CouchDB log (at the INFO level).
Arguments:
message – Message to be logged
function(doc){
log('Procesing doc ' + doc['_id']);
emit(doc['_id'], null);
}
After the map function has run, the following line can be found in CouchDB logs (e.g. at /var/log/couchdb/couch.log):
[Sat, 03 Nov 2012 17:38:02 GMT] [info] [<0.7543.0>] OS Process #Port<0.3289> Log :: Processing doc 8d300b86622d67953d102165dbe99467
Who would have guessed :)
I'm pretty sure you can't write to couch.log from a view, it's a sandboxed system.
Getting a record of connections to the server is possible though. Here's a dump from my couch.log, with an HTTP error in there:

You can see it has the VERB PATH CODE format for each line, so you can filter that for whatever you need. (Unauthorized is 401) You can also access the log through /_log. Details on that are here:
http://docs.couchdb.org/en/latest/api/server/common.html#log
To get all that information, you'll need to have the log level set to info. You can do this at the config screen in futon.
To do it server-side, you'd probably need to use node.js or something like that. Just have it consume the /_log endpoint, and filter each line by the HTTP response code.
From Netbeans 6.9.1 I chose to include Glassfish 3 on install. I then created a new web application and selected JSF 2.0, so Netbeans created a "hello world" type app to start from. However, running it brings up errors, but it's better now that I've modified glassfish a bit. However, why is there still a database problem when I'm not even using a database?
now I'm getting:

However, that "database" still on the wrong port for some reason(?).
I modified one domain.xml, but there's also one in template:
thufir#tleilax:~$
thufir#tleilax:~$ nl /home/thufir/glassfish-3.0.1/glassfish/domains/domain1/config/domain.xml | grep 8081
189 <network-listener port="8081" protocol="http-listener-1" transport="tcp" name="http-listener-1" thread-pool="http-thread-pool" />
thufir#tleilax:~$
thufir#tleilax:~$
thufir#tleilax:~$ ll /home/thufir/glassfish-3.0.1/glassfish/lib/templates/domain.xml
-rw-rw-r-- 1 thufir thufir 12804 2010-06-08 15:37 /home/thufir/glassfish-3.0.1/glassfish/lib/templates/domain.xml
thufir#tleilax:~$
However, glassfish now seems to be running ok, although I would prefer it on 8080 as it would be by default. I just don't understand why there's a database connection to, apparently, no database -- certainly not one I selected.

It means the port 8080 has already been used by other process in your system.
try to run sudo lsof -i :8080 to see what process/service runs on that port and terminate it.
Another solution is to completely change the port number.
I had this kind of problem last time when installing Netbeans for second time a year ago but as far as I remember I had v2 glassfish and v3 beta (2 years ago).
What I did is to change the port number. Have a look at domain.xml (probably) and change the port number 8080 to something else (unoccupied port).
