Hi
our server is running 4.10.1-1+squeeze1~bpo50+1 on debian lenny and
recently we have started seeing gazillions of log messages from this
code in network.c:
if (se->data.server.userdb == NULL)
{
c_complain (LOG_NOTICE, &complain_no_users,
"network plugin: Received signed network packet but can't verify it "
"because no user DB has been configured. Will accept it.");
return (0);
}
Could someone more familiar with the code explain what would trigger this?
The clients are a mix of various 4.x versions, none are 5.x.
See the cryptographic setup section:
https://collectd.org/wiki/index.php/Networking_introduction
My guess is that at least one of the clients sending to your server has
been configured in their network plugin with SecurityLevel of either
"Sign" or "Encrypt".
But your server hasn't defined the AuthFile attribute in their network
plugin configuration.
