what does error -2077 trying to add listener mean

Hi,

I've configured rsyslog to use relp as transport protocol.
sw version: rsyslog-relp-3.21.3-4 and rsyslog-3.21.3-4.

in the log I see these messages:
2009-03-16T16:12:10.769408+01:00 zeus-log01-2 rsyslogd: [origin
software="rsyslogd" swVersion="3.21.3" x-pid="3239"
x-info="http://www.rsyslog.com"] restart
2009-03-16T16:12:10.769447+01:00 zeus-log01-2 rsyslogd: error -2077
trying to add listener
2009-03-16T16:12:10.769458+01:00 zeus-log01-2 rsyslogd: the last error
occured in /data/etc/rsyslog/rsyslog.conf, line 6
2009-03-16T16:12:10.769470+01:00 zeus-log01-2 rsyslogd: the last error
occured in /data/etc/rsyslog/rsyslog.conf, line 7

The config line in question read:

------snip
# Global
$ModLoad imudp.so
$ModLoad imtcp.so
$ModLoad imrelp.so
$UDPServerRun 514
$InputTCPServerRun 514 <-- line 6
$InputRELPServerRun 2514 <-- line 7

$DirCreateMode 0755

-------snap

netstat -an| grep 514 shows all configured udp and tcp ports open.

So where can I find a description of error -2077?

Thanks in advance

Thomas

There should be informtion on that error on the web, but 2077 is "could not
bind to port". A short reference can be found in git in file
./runtime/rsyslog.h

Not sure where it orginates from in this case...

Hi Rainer,

there is only one place where RS_RET_COULD_NOT_BIND is returned:

runtime/nsd_ptcp.c

numSocks = 0; /* num of sockets counter at start of array */
for(r = res; r != NULL ; r = r->ai_next) {
sock = socket(r->ai_family, r->ai_socktype, r->ai_protocol);

[ lots of magic ]

}

if(numSocks == 0) {
dbgprintf("No TCP listen sockets could successfully be
initialized");
ABORT_FINALIZE(RS_RET_COULD_NOT_BIND);
}

I have no idea why the OS reports the Sockets open and messages get
received, maybe there is a minor problem in the code, but somehow it
works...

This sounds like some quirk with IPv6...
