is there a written spec for exactly what the amprnet portal needs to do and keep track of? Might it be available for review and reading? Thanks, Eric Fort AF6EP

Brian, Interesting, thanks for sharing. Amplifiers are something I really think the ham community needs to think about. They exist, but like you say, but at outrageous prices. i.e.: http://www.shireeninc.com/300-500mhz-20-watts-outdoor-amplifier/ I have been reading Dubus magazine (focused on microwave), hoping to read more data oriented construction articles. I am much in the same line of thinking. 1200 and 9600 is really not worth re-deploying in 2014. The regulatory landscape needs some major changes so that manufactures can put something different in the hands of many. Steve

My segment 44.98.254.0/24 is being used for one PtP data link now, and some asterisk based repeater controllers. I have email for kb9mci.net on it (but need to get SWIP/PTR going Brian ;). My intent is to fire up some of the doodle labs 23cm link cards as we get another repeater site and link it over on that space. As this grows over the next couple years it will be quite a high speed data network with VoIP as the primary purpose. Doing all the RF links in the ham bands is part of the fun. (anyone have a OFDM rated 20-30 watt amp for 23cm that's not $2k?) One of the pet peeves I've have is not being able to access the other AMPR net space with out tunnels. I think tunnels are just an ugly hack IMO. I'd like to see us transition into more of a regionally routed network, rather than the few BGP nets and UCSD gateway. Well aware of how much time this would take I'm not ready to write up a proposal just yet (ampRFC?). If anyone wants a subnet I'd be happy to route it to you, as I'm not using the whole /24 and won't be for some time. Global routing policies being what they are, a /24 is the smallest subnet you can announce. My interest lies in high speed networks, and see little to no value in 9600 baud IP networks in 2014 :) 73's -- Bryan Fields 727-409-1194 - Voice 727-214-2508 - Fax http://bryanfields.net

Along the same lines, I have been wondering: Will the portal design/code be available for other regional BGP enabled 44net gateways to implement? It would be interesting to hear more about how those other BGP announced chunks of 44net are using the space.

Are there (still) issues with SMP and/or x86_64 and AX25 on linux?
by Robert Brose 25 Jan '14

25 Jan '14

For a quite a while I've been getting "bugs in scheduling while atomic" kernel messages. I seem to recall there were some issues with SMP and mkiss at some point in the past. This isn't a hardware problem since the issue remains after putting together a completely new system. This is currently a machine running debian wheezy i386 userland with a x86_64 kernel. ax25_rebuild_header is in all of these dumps. Seems suspicious. The hardware is a i7-4770K CPU @ 3.50GHz with 16 gigs of ram, dual ethernet ports (acting as a router), a serial kiss port to a TNC and an AXIP port. ham related modules in use: ipip 12941 0 tunnel4 12629 1 ipip ip_tunnel 21436 1 ipip netrom 36534 4 mkiss 17161 2 ax25 54676 60 mkiss,netrom dmesg [10433.518914] Hardware name: MSI MS-7850/Z87-G41 PC Mate(MS-7850), BIOS V1.2 06/07/2013 [10433.518915] 0000000000000000 ffff88002e21e7c0 ffffffff814b98af ffff8803f603e000 [10433.518917] ffffffff814b6f16 ffff88040eb93800 ffffffff814bd1ad 0000000000000000 [10433.518918] ffff88041fac3bd8 ffff8803f603ffd8 ffff8803f603ffd8 ffff8803f603ffd8 [10433.518919] Call Trace: [10433.518920] <IRQ> [<ffffffff814b98af>] ? dump_stack+0x41/0x51 [10433.518927] [<ffffffff814b6f16>] ? __schedule_bug+0x46/0x55 [10433.518928] [<ffffffff814bd1ad>] ? __schedule+0x5cd/0x780 [10433.518931] [<ffffffff8108d3dd>] ? __cond_resched+0x1d/0x30 [10433.518932] [<ffffffff814bd3d7>] ? _cond_resched+0x27/0x30 [10433.518934] [<ffffffff814bc209>] ? mutex_lock_interruptible+0x9/0x40 [10433.518942] [<ffffffffa0309c08>] ? rp_write+0x68/0x340 [rocket] [10433.518943] [<ffffffffa08adf0d>] ? ax_xmit+0x1ad/0x440 [mkiss] [10433.518946] [<ffffffff813d2669>] ? dev_hard_start_xmit+0x319/0x500 [10433.518948] [<ffffffff8106ac18>] ? internal_add_timer+0x18/0x50 [10433.518950] [<ffffffff813f010d>] ? sch_direct_xmit+0xfd/0x1d0 [10433.518951] [<ffffffff813d2a40>] ? dev_queue_xmit+0x1f0/0x490 [10433.518954] [<ffffffffa08988f8>] ? ax25_rebuild_header+0x108/0x2b0 [ax25] [10433.518956] [<ffffffff813d9e3d>] ? neigh_compat_output+0x8d/0xa0 [10433.518957] [<ffffffff8140a4d1>] ? ip_finish_output+0x1b1/0x3a0 [10433.518959] [<ffffffff8143ec85>] ? igmp_ifc_timer_expire+0x175/0x280 [10433.518960] [<ffffffff8143eb10>] ? igmp_group_added+0x170/0x170 [10433.518962] [<ffffffff8106ab1c>] ? call_timer_fn+0x2c/0x100 [10433.518963] [<ffffffff8143eb10>] ? igmp_group_added+0x170/0x170 [10433.518964] [<ffffffff8106c0d5>] ? run_timer_softirq+0x1f5/0x2a0 [10433.518967] [<ffffffff812860f1>] ? timerqueue_add+0x61/0xb0 [10433.518969] [<ffffffff81063bbe>] ? __do_softirq+0xde/0x220 [10433.518970] [<ffffffff814c875c>] ? call_softirq+0x1c/0x30 [10433.518973] [<ffffffff810155b5>] ? do_softirq+0x75/0xb0 [10433.518974] [<ffffffff81063e65>] ? irq_exit+0xa5/0xb0 [10433.518977] [<ffffffff810407cb>] ? smp_apic_timer_interrupt+0x3b/0x50 [10433.518979] [<ffffffff814c7a9d>] ? apic_timer_interrupt+0x6d/0x80 [10433.518979] <EOI> [<ffffffff814c8a2c>] ? sysenter_dispatch+0x7/0x21 Thanks for any ideas.

DNS records 44.131.56.0/24
by Nick G4IRX 20 Jan '14

20 Jan '14

Hi, I've checked DNS A records for various hosts in the net that I'm co-ordinator for and they resolve but to to obsolete records. I've entered some new records via portal.ampr.org, expecting them to come to me for approval but as yet, no email! The correct entries should be - gw.g4irx.ampr.org IN A 44.131.56.9 g4irx.ampr.org IN A 44.131.56.10 Ideally the entire 44.131.56.0/24 block could be deleted as we've started afresh re-allocating addresses. Any suggestions to get this fixed? Thanks, Nick G4IRX.

Nick, I think this part of the portal does not work. It would be better if it were disabled until time can be spent on it. You need to send the updates of your address space to the ampraddr robot as before. To delete a block, first download the existing allocations from ftp://hamradio.ucsd.edu/pub/ampr.tar.gz, isolate what you want to delete, edit the "IN" to "DEL" and submit it to the robot. Rob

new ip
by Brian Rogers 20 Jan '14

20 Jan '14

For those who wish to try and relink my new IP is: 76.28.121.159 I haven't received an encap file yet and the ISP screwed things up on their end which most likely will be resolved sometime tomorrow. If I set you up double check your startup file to see if I put in a static route to myself in your file. If so please delete it and let RIP handle the rest. -- 73 de Brian Rogers - N1URO email: <n1uro(a)n1uro.ampr.org> Web: http://www.n1uro.net/ Ampr1: http://n1uro.ampr.org/ Ampr2: http://nos.n1uro.ampr.org Linux Amateur Radio Services axMail-Fax & URONode AmprNet coordinator for: Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, Pennsylvania, Rhode Island, and Vermont.

Re: [44net] Help with 44.152 subnet
by Gabriel Medinas 19 Jan '14

Hello friends, After a hard weekend installing 2 JNOS machines to serve each a middle split 44.152.0.0./16 The 44.152.128.1 working the second part of the subnet (yv5sat.ampr.org) 44.152.128.0/17 in this first time the second subnet that cover all cities out of Capital District in YV. The other first split 44.152.0.0/17 Capital District with yv5kxe.ampr.org 44.152.0.60, this machine now with ubuntu desktop (3 formats this weekend) to reach the cause of the problem with RIP and encap tunnels. Thanks to Tom SL2LOB and Pedro LU7ABF, that help me to test and find the solution of why dont work the ampr tunnels in my system. Yet the RIP dont work but may find a solution, the mayor problem is the impossibility to SYN encap packets datagrams trougth Internet, think first the Ubuntu, then the JNOS, or any ISP ADSL filter, and last find the problem in the Tp-Link firewall TL-R480T that dont want pass any encapsulated datagram, I check all parameters but dont is possible, change to other D-link with DD-WRT v24-sp2 and work perfect. Meanwhile I find other firewall to change the TL-R480T TPLINK the first 44.152 split subnet is down, only with comercial IP yv5kxe.org. Thanks for your attention. 73 de Gabriel YV5KXE.
