Repeatedly message "Error returned from read()" in log file #70

Closed reinerwill closed 2 years ago

reinerwill commented 2 years ago

Hi, I've installed the current ircDDBGateway package on our CentOS 7 gateway DB0HRF, already running ICOM G3. On an old G2 installation I found the trick of Hansjuergen DL5DI to replace the script gwstart.sh with a dummy loop script. This seems to work so far. So G3 is runniing the database for registration only, while dplus and dsm is stopped. But short after the start "systemctrl start ircddbgatewayd.service" I see messages "Error returned from read()" raising in the log file, about 190 time every second. On my radio I hear the messages like "Not connected", but can't connect to any reflector for test.

grep "00:06:06: Error" /var/log/opendv/ircDDBGateway-2022-01-03.log
...
E: 2022-01-03 00:06:06: Error returned from read()
E: 2022-01-03 00:06:06: Error returned from read()
E: 2022-01-03 00:06:06: Error returned from read()
...
[root@dstar dsgwd]# grep "00:06:06: Error" /var/log/opendv/ircDDBGateway-2022-01-03.log | wc -l
192
[root@dstar dsgwd]# grep "00:06:07: Error" /var/log/opendv/ircDDBGateway-2022-01-03.log | wc -l
191
[root@dstar dsgwd]# grep "00:06:08: Error" /var/log/opendv/ircDDBGateway-2022-01-03.log | wc -l
192

I can't figure out the root cause of this problem. Any idea how to debug this? I'm thinking of strace or so, but have not really an idea where to start. Please help!

Hi,

Nobody can help me, as it seems, but I still hope someone can. In the meantime I have the idea that it could be a rights issue. In this version the daemon is started as user opendv. To what groups do this user need to belong to? The current config is like this:

[root@dstar ~]# grep opendv /etc/group
dialout:x:18:opendv
audio:x:63:opendv
opendv:x:993:

Is there any group missing maybe?

Hi,

There was an idea if the permission for the log file and folder are wrong, but they are good, logs are written. In the beginning of the log everything looks good, but after a while it continuously shows this error:

It's very sad that this amazing project is not monitored, and no one can help. I'm still facing continuously "Error returned from read()" messages in the log. The system is not usable. You can't transmit neither link to any reflector. In the meantime I tried also on a Debian server beside the CentOS I tried before. Same problem.

I'm really sad! :-( Reiner, DH9FAX

g4klx commented 2 years ago

Please ask on the OpenDB@groups.io group, that is where support occurs.

reinerwill commented 2 years ago

Hi Jonathan,

I didn't found OpenDB group related to amateur radio. I guess you meant OpenDV, but I've already placed my issue there two month ago with no luck. I will try again...

IvanGirderboot commented 2 months ago

@reinerwill I ran into this issue today and traced it down in the code. You may or may not care, but I'm posting it here for posterity.

My guess is that you're not running this as root, which is good practice. However, the binary needs root-level access in order to manipulate the networking stack, including being able to create interfaces for the data module (if you have one defined).

You have two choice here:

To add the capability, run sudo setcap 'cap_net_admin=ep' /path/to/ircddbgateway-binary and restart the process.

Hope this helps someone in the future!

Note: A trailing space in the module name (A vs A) will trick the code into thinking a data module is in the system (normally named AD) and attempt to create the data device,
