New subject: Intermittent host connectivity issues Was: New to the Group
Chris KQ6UP,
I noted the same behavior last month regarding my station connecting to others. You may
wish to read over the January 2013 discussions regarding this.
It was determined that stations were using various Network Operating Systems and that
users assumed services are available that were not.
It was noted that there was difficulty with a JNOS stations reaching my station, this
problem dissappeard when I maintained an open Telnet connection to them.
We came to a concurrence that for testing it's good to have all online 44 IPs respond
to ping. Please note traceroute employs UDP ports 33434-33534, when setting up my
router's firewall, I had to especially make sure I permitted echo-request and UDP
ports 33434-33534 to my AMPR Hosts.
Others note that they perform a Telnet to AMPR Hosts in order to test them; that is not
advisable, as not all AMPR IP hosts are Telnet enabled.
Also, feel free to Ping or Traceroute from the following address:

New subject: DNS
All,
I'm currently able to perform zone transfers for ampr.org and 44.in-addr.arpa from the
AMPR Nameservers using BIND, I have a DNS server available at 44.60.44.3, it resolves the
entire Internet for 44 hosts.
Also, only RF transmissions in the US are governed by the FCC (for Part 97 purposes);
therefore, the ID must be in the transmission in some form or fashion, not necessarily in
the DNS record. As all IPs are issued to an amateur, the IP can be identified (for the
Internet's sake). If you are concerend about over the air ID, this will not solve the
issue, as you are not identifying yourself in the process (which is the requirement).
IP-over-AX.25 does not have such an issue as 802.11, which may use SSID, MAC Address
Encoding, or perform some other regular transmission over RF-method that identifies your
station.

It should be noted that Windows actually uses ICMP type 30 packets for
it's traceroute function:
ftp://ftp.iana.org/assignments/icmp-parameters/icmp-parameters.txt
where as most Unix systems use UDP port 33434 (I don't think it uses a
range of ports.. just this one):
ftp://ftp.iana.org/assignments/port-numbers
Ps. Thanks for putting up that AMPR test portal Lynwood.. VERY helpful!

Let me know if you're looking for VoIP peers. I've only got a very few
numbers, but I'm willing to let you call them toll free until or unless
things get out of hand.
