[Spread-users] Trouble Talking Between 2 Servers

In your config you set up Spread to use port 4803, and you said you opened
your firewall for traffic on that port, in addition you need to make sure
that 4803 is open for both UDP traffic as well as TCP/IP traffic. Also you
need to open port 4804 for UDP traffic, and if you want to use spmonitor,
you will also need to open UDP port 4805.

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).
