Reverse Delegation
by Fredric Moses 03 Oct '15

03 Oct '15

I know a couple of groups now have proper reverse delegation of DNS for their subnets… Wondering who to drop a line to so I can get 44.103.0.0/19 delegated to a.ns.mi6wan.net and b.ns.mi6wan.net ? Didn’t see it in the portal or wiki and my notes from a few months ago are foggy... -- Fredric Moses - W8FSM - WQOG498 fred(a)moses.bz

AMPRNet Munge script package

Folks: I am using a pretty old munge package. I looked on the wiki/portal but I could not find the scripts, just references to it. Is it hidden somewhere? Thank you, Assi

Just a friendly reminder that M$ will be releasing Windows 10 online, and millions of desktops are expected to suck up bandwidth because of this. Packet loss may be a very normal thing tomorrow. -- A computer once beat me at chess, but it was no match against me in kick-boxing - Emo Phillips 73 de Brian Rogers - N1URO email: (see above) Web: http://www.n1uro.net/ Ampr1: http://n1uro.ampr.org/ Ampr2: http://nos.n1uro.ampr.org Linux Amateur Radio Services axMail-Fax & URONode http://uronode.sourceforge.net http://axmail.sourceforge.net AmprNet coordinator for: Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, Pennsylvania, Rhode Island, and Vermont.

It is interesting to see that the implementation of home connections varies so much over the world. Over here there is a legal obligation to always be able to produce the name and address of the subscriber that owned an IP address at a certain point in time, and it appears that most providers have taken the easy way of assigning a fixed IP to each subscriber. DSL connections all have a fixed IP. Cable connections usually have an IP that is fixed as long as you do not turn off the cable modem for a few days or so. There is no hourly or daily cycling of addresses anywhere. Truly dynamic IP is only in use here on mobile connections, and often they are behind NAT so not possible to use an ipip tunnel on them anyway. I have implemented OpenVPN and IPsec on our gateway so those users still can get connected to AMPRnet. I would think that when your address really changes hourly, and you want to be on an AMPRnet tunnel, it would be best to arrange something similar, a VPN to a system on a fixed address. It should be easy to arrange for such a thing, e.g. with a group that share a cheap VPS for it that can also be used for mail, a webpage etc. Rob

So presumably something is wrong, but it may not be the same firewall rules. Those were probably applied to input, while this is something at output or a problem with the routing / rules. I think it worked OK before. Rob

ipip.routes and rc.local
by Assi Friedman 27 Jul '15

27 Jul '15

More of a Linux question, but worth a shot since others have probably been to this rodeo before. I have come across an issue starting AMPRnet automatically at boot. The ipip.routes script seems to fail starting the tunl interface when ran by the system by the rc.local script. Interestingly, when ipip.routes is ran in the crontab (nightly update) there are no issues. So this is specifically related to the rc.local script. Anyone else run into this issue? Thanks, Assi kk7kx

Packet loss through UCSD?
by Assi Friedman 27 Jul '15

27 Jul '15

Folks: I just brought my ampr host back online after moving to a new facility. My initial configuration is to enable internet <-> amprnet connectivity. So I have all traffic in both incoming and outgoing directions routed IPIP'd via UCSD. The host is Linux Fedora based (will be transitioning to CentOS sometime...) and I used the guidelines set on the wiki. One unexpected thing is packet loss. I am seeing very slow performance using this approach and rather poor packet loss. Are there any issues or QoS policies implemented on the amprnet router at UCSD? Thank you, Assi kk7kx/4x1kx AMPRNet host: kk7kx.ampr.org (icmp & http only for now) Internet host: phantom.kiloxray.com (hosts kk7kx)

Are there benefits to using the API as compared to wgeting (yup, it's a word) the encap file?
