grepping the source:
if (!verify(wd.wd_hostname, sizeof wd.wd_hostname)) {
syslog(LOG_WARNING, "malformed host name from %x",
from.sin_addr);
continue;
}
So it's a hex representation of the IP address
02 38 d4 8d = 2.56.212.141 (or 141.212.56.2, I'm never sure about this)
wd_hostname is *your* hostname, as initialized at the begin of main().
/*
* Establish host name as returned by system.
*/
if (gethostname(myname, sizeof(myname) - 1) < 0) {
syslog(LOG_ERR, "gethostname: %m");
exit(1);
}
if ((cp = index(myname, '.')) != NULL)
*cp = '\0';
strncpy(mywd.wd_hostname, myname, sizeof(mywd.wd_hostname) - 1);
mywd.wd_hostname[sizeof(mywd.wd_hostname) - 1] = '\0';
So, what is the hostname of your machine?
It shouldn't contain anything but 0-9, a-z and A-Z and its size
should be >0. See the verify function for this (hmmm... shouldn't
the minus (-) be allowed in this?)
Edwin, loves having the source-code!
