Bill, I attempted to look through my records for 138.88.77.89 on my interface and I see quite a bit of packets from you - so much so that it crashed my NetFlow console upon searching your IP with a setting of 10,000 flows. I am receiving encapsulated packets from you, and it seems you've pointed traffic towards me.

Need TraceRoute from UCSD router
by R P 28 Jan '20

28 Jan '20

Hi there Im trying to debug why one of our hams dont have tunnel up an running (or actually why one day it stopped working for him ) I suspect there are a routing problem from UCSD side to his ISP I wrote Brian mail asking to login to the UCSD HAM router and make a trace route to this local ham so i can track the problem Who can help me now ? is there anyone that have the ability to login and make trace route maybe Chris ? or any other solution ? The MikroTik Router he have declare that no route to UCSD and the tunnel status is down but from the router side ping can be done to UCSD ham router Is there any chance to do a web interface on UCSD Router that will give the option to the users to make trace route from there to a certain destination using the 44 and the non 44 interface ? something like this https://ping.eu/traceroute/ Thans forware for any assistance Ronen - 4Z4ZQ

Bill, The crash truncated the IPs in the search; showing my IP. Forcing a dynamic IP change on WAN helped me realize my error.

PKTerrors.

Hi, Just been looking through https://gw.ampr.org/private/pkterrors.txt and I noticed there's entries for the external IP for the net I run. I'm running 44.131.170.0/30 with a RaspberryPi on 44.131.170.1 using IPIP with amprd, external IP address 90.155.50.1 The errors are like: 90.155.50.1 51.89.173.198 2 [19] dropped: non-44 inner source address What does this mean? And I can't seem to ping to 44.131.170.1 from the big bad internet, is this related? Thanks. Bill (M1BKF)

Bill, That error means that you are encapsulating an IP that does not equal a 44 IP (e.g. you're improperly sending multicast, broadcast or your Public IP onto the tunnel). Ensure that you only send 44-net SRC IPs inside the tunnel. Also, any 44 IP that you want to reach the Internet must have a DNS entry in the AMPR.ORG and 44 reverse zones. That seems to be properly setup already: 1.170.131.44.in-addr.arpa name = m1bkf.ampr.org. --- I ping and receive no reply - this is a TCPDUMP of my tunnel: 21:23:10.793135 IP (tos 0x0, ttl 64, id 46020, offset 0, flags [DF], proto IPIP (4), length 104) 138.88.77.89 > 90.155.50.1: IP (tos 0x0, ttl 64, id 48759, offset 0, flags [DF], proto ICMP (1), length 84) 44.60.44.1 > 44.131.170.1: ICMP echo request, id 19216, seq 7, length 64 21:23:11.793459 IP (tos 0x0, ttl 64, id 46092, offset 0, flags [DF], proto IPIP (4), length 104) 138.88.77.89 > 90.155.50.1: IP (tos 0x0, ttl 64, id 48962, offset 0, flags [DF], proto ICMP (1), length 84) 44.60.44.1 > 44.131.170.1: ICMP echo request, id 19216, seq 8, length 64 21:23:12.793801 IP (tos 0x0, ttl 64, id 46294, offset 0, flags [DF], proto IPIP (4), length 104) 138.88.77.89 > 90.155.50.1: IP (tos 0x0, ttl 64, id 49447, offset 0, flags [DF], proto ICMP (1), length 84) 44.60.44.1 > 44.131.170.1: ICMP echo request, id 19216, seq 9, length 64 21:23:13.794158 IP (tos 0x0, ttl 64, id 46674, offset 0, flags [DF], proto IPIP (4), length 104) 138.88.77.89 > 90.155.50.1: IP (tos 0x0, ttl 64, id 49657, offset 0, flags [DF], proto ICMP (1), length 84) 44.60.44.1 > 44.131.170.1: ICMP echo request, id 19216, seq 10, length 64 21:23:14.794465 IP (tos 0x0, ttl 64, id 47472, offset 0, flags [DF], proto IPIP (4), length 104) 138.88.77.89 > 90.155.50.1: IP (tos 0x0, ttl 64, id 50140, offset 0, flags [DF], proto ICMP (1), length 84) 44.60.44.1 > 44.131.170.1: ICMP echo request, id 19216, seq 11, length 64 73, - Lynwood KB3VWG

Hello Matt, You may by now have found a solution to your problem; I had a similar problem when setting up a remote node last week via a mobile phone sim card ( cell net phone ! ). I found I could not connect from the remote node until I removed the default entry in iptables and used ip rules to get a two way connection. Regards, Ian.. A totally in-experienced user <smile>

Help troubleshooting AXIP link
by VE3OY Matt 24 Jan '20

24 Jan '20

Hello 44Net. I'm looking for some help from those who have experience! I have recently set up my first AXIP link through the 44Net, but I'm having trouble connecting to my AXIP partner. My IP is 44.135.88.200 and my partner is 44.135.32.201 So far I can TELNET and PING back and forth from ANY 44 node, yet all attempts to make a AX25 connection to my AXIP partner fail. I can TELNET/PING from my partner to my node okay. I can TELNET/PING to my partner from my node okay. I can PING the 44 gateway without issue. I have also been broadcasting my NODES table to my partner. My partner does not seem to "hear" my CONN REQ's or NODES broadcasts. My partner is also broadcasting his NODES table to me. I am not hearing his broadcasts. Using TCPDUMP and WIRESHARK, I can see the traffic going out my tunnel to my regional gateway. I have tried to capture AX25 packets FROM my partner ... nothing heard. I have been able to capture AX25 packets TO my partner ... all looks correct. I have been able to capture packets when TELNETing or PINGing. TRACEROUTEs to my partner work fine (2 hops). My situation is a little more complex because I am not going direct to the UCSD gateway. Instead, I am sending all my 44Net traffic through my regional gateway (44.135.88.252). It has been suggested that my ISP may be "source filtering", but i have no way of verifying that. I am running both my router and node on a Raspberry Pi (I know ... plug your nose! LOL) I am using IPTABLES, which I have disabled for testing to see if it was interfering (it wasn't). My router/node is behind a CPE router, and is in the DMZ. I have several AX-UDP ports working fine. So here are my questions: Does it sound like I am suffering from source filtering? How can I verify whether my ISP is source filtering? What have I overlooked in my troubleshooting? What would you suggest as my next step? Any and all suggestions are welcome. I'm going bald quickly pulling out my hair! Thanks in advance, Matt VE3OY (FN03gq) Toronto, Canada -- /My mind is like a web browser. 27 tabs are open, 9 aren't responding, lots of pop-ups...and where is that annoying music coming from?/
