why is there 4 of each? is there a legitimate need for the loopbacks? also, may i turn off the 4 udp and leave only the 4 tcp? if so how please. and furthermore, i beleive tls is security over tcp , if so, how may i turn on tls ?
thanks aaron

There was a privious post on this exactly like yours. Anyway...
"children=4" mean that there will be 4 UDP, 4 TCP and 4 loopback listenters on your SER, when you start it (you can check with "serctl ps" to verify).

In fact this number is the number of listeners for each interface you bind SER to.
So, if you only have tcp listen statements there won't be UDP nor loopback listeners.
Making serctl ps will present this information together with the rest of processes that SER starts.

There are plenty of legitimate uses for having SER listen on a loopback address. I have one server that runs two instances of SER, one for SIP messaging and the other as a SIMPLE<->XMPP (jabber) gateway. They communicate over the loopback interface.
To turn off different interfaces just modify your listen statements. For instance if you only want things to listen on eth0 add 'listen=eth0' to your global statements. If you want just UDP on eth0 use 'listen=udp:eth0'.
FWIW, a good rule of thumb is to run services blacklist centric (ie. deny everything by default and then allow only the things you want) so the more specific your listen statements are the easier it is to anticipate the traffic you will receive.
