[Spread-users] Trouble Talking Between 2 Servers

[Cameron Stuart]

Thanks for your help dustin, we actually had a couple of problems,

1) We use FreeBSD, so the port had to be opened in /etc/services
2) The network addresses we were using were incorrect.
For our internal network (10.1.1.x)
the segment address should be 10.255.255.255, instead of 10.1.1.255 which is what we had

On a 192.168.1.x network 192.168.1.255 as a segment address will work

Thanks again
Cheers,
Cam

I keep having problems like this, usually caused by:
 * firewalling 4803 or 4804
 * different names for boxes in different configuration files
 * different IPs for boxes in different configuration files

Diagnostics that I have usd involve:
 * watching spread's logs to see what daemons it thinks are in the
   group:

[Fri 13 Oct 2006 02:43:50] Configuration at box1 is:
[Fri 13 Oct 2006 02:43:50] Num Segments 1
[Fri 13 Oct 2006 02:43:50]  4   192.168.1.255     4803
[Fri 13 Oct 2006 02:43:50]      box2                    10.1.1.102
[Fri 13 Oct 2006 02:43:50]      box1                    10.1.1.101
[Fri 13 Oct 2006 02:43:50]      box3                    10.1.1.103
[Fri 13 Oct 2006 02:43:50]      box4                    10.1.1.104
[Fri 13 Oct 2006 02:43:50] ====================

 * watching spmonitor to see if the token is circulating between boxes (rounds
   should be counting up in sync)

 * using spuser to join the same group on each box

That takes any question about the scripts out of the picture (although from my
understanding of Perl, they looked fine).
