<div class="moz-cite-prefix">So how do you go about using this:<br>
<br>
First you need to create one or two RBN user(s). Now you can use
any call you<br>
like and it won't be visible outside of the node. I call mine
SK0MMR<br>
and SK1MMR. One of these connects to the "standard" RBN port that<br>
outputs CW, BEACON, DXF, PSK and RTTY spots, and the other
connects to<br>
the RBN port that just outputs FT4 and FT8 spots.<br>
<br>
set/rbn sk0mmr sk1mmr<br>
<br>
Now create connect scripts in /spider/connect/sk0mmr (and
similarly<br>
sk1mmr). They look like this:<br>
<br>
/spider/connect/sk0mmr:<br>
<br>
connect telnet telnet.reversebeacon.net 7000<br>
'call:' '<node callsign here'<br>
<br>
/spider/connect/sk1mmr:<br>
<br>
connect telnet telnet.reversebeacon.net 7001<br>
'call:' '<node callsign here'<br>
<br>
Now put them in your local crontab in /spider/local_cmd/crontab:<br>
<br>
* * * * * start_connect('sk0mmr') unless connected('sk0mmr')<br>
* * * * * start_connect('sk1mmr') unless connected('sk1mmr')<br>
<br>
This will check once every minute to see if each RBN connection is<br>
active, you can check what is connected with the 'links' command:<br>

The RBN connections are sometimes dropped or become stuck. I have
a<br>
mechanism to detect this and it will disconnect that RBN
connection<br>
and, by this means,it will be automatically reconnected by the<br>
crontab, just like any other (normal) node.<br>
<br>
I use the crontab, rather than restarting immediately after<br>
disconnection, to prevent race conditions (or just slow them down
to<br>
one disconnection a minute).<br>
<br>
The first time a connection is made, after node startup, there is
a 5 (configurable)<br>
minute pause before RBN spots come out for users. This is done to
fill<br>
up (or "train") the cache. Otherwise the users will be overwhelmed
by<br>
spots - it slows down reasonably quickly - but experiment shows
that 5<br>
minutes is a reasonable compromise. The delay is configurable,<br>
globally, for all RBN connections, but in future is likely to be<br>
configurable per connection. Basically, because the FTx RBN data
is<br>
much more bursty and there is more of it (except on CW contests),
it<br>
could do with a somewhat longer training period than the CW etc
RBN<br>
connection.<br>
<br>
If a connection drops and reconnects. There is no delay or extra<br>
training time. If the node is stopped and restarted within a few<br>
minutes, then no training time will occur.<br>

<pre wrap="" class="moz-quote-pre">Hi All,
How to connect RBN SKIMMER on DXSPIDER ?
I have this information
IP for SKIMMER :
44.52.120.51
44.10.10.51
telnet.reversebeacon.net
And port is 7000 and 7001
Can you help me to connect sk0mnr and sk1mnr ?
Thanks for your answer.
