I am passing empty string (but not null) as ip and ports in range
12345-12445. If I use 127.0.0.1 as ip, it fails in bind socket

still investigating ;)<br>

right now one of the player creates socket and just

I am testing connectivity on the same machines
constantly, so I dont see any reason why it should work
for 3 times in a row and then wouldnt... and it's a bit
weird moment - creating host, i would expect it to fail
when actually trying to connect<br>

If both your players try to connect at the same time
then they should get through after a retry or two.<br>
<br>
Although there is many types of nat's so it might
not always work.<br>

I am using enet library in conjunction
with gamespy. I use gamespy to create
socket, connect to lobby, select
opponent and do the NAT punch-through.
In next step I close gamespy socket,
initialize enet library and try to
create enet host with same port (in my
case I pass ip as empty string) and then
start connection to other party. It
works, but not always. I am using three
computers right now: pc vista, pc xp and
mac osx 10.7.4. On mac sometimes (not
always) I cannot create enet host (even
if i try to create host with different
ports, 100 retries), here's the code: <br>
<br>
retries = 101; <br>
enet_address_set_host
(&enet.gAddress, ip); <br>
do { <br>
enet.gAddress.port = port; <br>
enet.gHost = enet_host_create
(&enet.gAddress , 1 , 2, 0 ,0 ); <br>
<br>
if (enet.gHost == NULL) <br>
{ <br>
printf ( "An error occurred
while trying to create an ENet
host(%s:%d).\n",ip,port); <br>
port++; // HACK <br>
} <br>
else <br>
printf( "host created.\n"); <br>
} while (enet.gHost == NULL
&& (--retries > 0)); <br>
<br>
Any ideas? <br>
Thank you! <br>
Martin <br>
