Yeah, it is libdns_sd doing idiotic thing - trying to connect to mdnsd over and over despite it \
is not running. I commited a fix to 3.5 branch (i will backport it to 3.4 too) that first \
checks if mdnsd is really running before trying to make any publishing.As a workaround for \
users with kdelibs 3.4.0-3.4.2 you can use following code (from \
kdelibs/dnssd/servicebrowser.cpp) as a workaround: bool dnssdAvailable() {        QFile \
f("/var/run/mdnsd.pid");        if (!f.open(IO_ReadOnly)) return false; // no pidfile        \
QString line;        if (f.readLine(line,16)<1) return false;        unsigned int pid = \
line.toUInt();        if (pid==0) return Stopped;           // not a pid        return \
(kill(pid,0)==0 || errno==EPERM);        // signal 0 only checks if process is running, mdnsd \
is probably owned // by 'nobody' so we will  get EPERM, if mdnsd is not running error will be \
ESRCH} if (dnssdAvailable) \
setDiscoveryInfo("_ksirk._tcp");_______________________________________________kde-games-devel \
