Hi Ben,
I looked into the implementation of X10 and found the lines that cause
the error in tcp.cc.
----------------------------------------
int TCP::connect(const char *host, unsigned port, unsigned retries,
bool noDelay)
{
int rc;
hostent *remoteInfo = gethostbyname(host);
fprintf(stderr, "Hostname: %s \n", host); // added by me for debug
purposes
if (!remoteInfo) FATAL("cannot resolve remote hostname");
----------------------------------------
The host that is resolved is "E6410.site" and not localhost. Adding my hostname
E6410.site to /etc/hosts solved my problem.
I don't know why, but X10 tries to start places using my hostname and
not localhost
as name.
Cheers,
Andreas
