Re: [webmin-l] RPC + iptables

[Andrew K. <ak...@co...>]

I recently picked up Jamie's new book and it specifically mentions 
Webmin's RPC
mechanism. There is an old method and a new method. The old method uses HTTP
requests exclusively and the new method uses a permanent TCP connection 
which
is faster and more reliable, but may fail if a firewall is blocking 
traffic between the master
and managed hosts. It uses ports 10001 and above, by default. The old 
protocol just
used the port on which Webmin accepts normal connections (10000). The 
range on
the new RPC mechanism which you will need for clusters are anywhere from 
10001
to 10100.  Hope this helps.
