44.133.48.66 !!!
by Maiko Langelaar 12 Apr '14

12 Apr '14

Good afternoon, It would see that 44.133.48.66 is popping, snmpding, and other amounts of traffic from time to time to various ampr.org systems and doing so *without warning* type of thing. I just got hit with a bunch of SNMP requests, others have been hit with POP requests. Can anyone find out who the owner of that particular system or network is, so that I can contact the entity or person. Or perhaps a bit more draconian, can someone deal with it. Thanks in advance.

Pi bug for ipencap?
by Brian Rogers 07 Apr '14

07 Apr '14

Greetings; I've noticed recently after doing a package update on the iproute packages I can no longer configure my tunnel interface tunl0. Mainly I'm trying to reset the ttl to 64 for traceroute to properly work. Everything I've searched comes up empty. Here's what I see: root@gw:/usr/local/bin# iptunnel show tunl0: ip/ip remote any local any ttl inherit nopmtudisc root@gw:/usr/local/bin# ifconfig tunl0 tunl0 Link encap:IPIP Tunnel HWaddr inet addr:44.88.0.1 Mask:255.255.255.255 UP RUNNING NOARP MULTICAST MTU:0 Metric:1 ttl is stuck on inherit and MTU autoconfigs to 0. This I know is set by nopmtudisc however if I try to adjust things: root@gw:/usr/local/bin# ip tunnel change tunl0 ttl 64 ttl != 0 and noptmudisc are incompatible root@gw:/usr/local/bin# ip tunnel change pmtudisc mode ipip add tunnel tunl0 failed: No such file or directory Why would it try to ADD? the command is CHANGE. Has anyone else suffered this before and if so what was the fix? Thanks in advance. -- 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.

Hack fix for Pi
by Brian Rogers 09 Jan '14

09 Jan '14

Greetings list members; While I still search for a true fix, a hack fix would be to create a tunl1 and route via that interface, however if you take tunl0 down, for some reason rip fails. If anyone has a better solution or a true fix, please relay it. Thanks in advance... -- 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.

Brian, I found the following in a Linux manual for the 'ip tunnel' command: nopmtudisc -- disable Path MTU Discovery on this tunnel. It is enabled by default. Note that fixed ttl is incompatible with this option: tunnels with fixed ttl always make pmtu discovery. If you create a tunnel that does not care about MTU state, it's also unconcerend about the 'distance' the packet has traveled, your eth interface would handle both tasks in that instance (being a 'dumb tunnel,' if you will). With nopmtudisc on, your 44Router would properly fragment the packet when transmitting on eth and sets the ttl on the ARPA Internet, as opposed to AMPRnet. If this command worked before you updated your IP utilities, it was probally due to the previous version not being written true to RFC. 73, Lynwood KB3VWG

How did you get that update? is it an update that is currently queued on "apt-get upgrade"? or was it something you installed yourself? (my Pi is still working but I'd like to know what to avoid) Rob

John, AFAIK, encap.txt file available via ftp site is updated once per hour, whilst encap.txt file available via portal.ampr.org is updated once update was made on the portal - immediately! -- Best regards. Tom - sp2lob

data bandwidth in other countries
by kb9mwr＠gmail.com 23 Dec '13

Hello all, I don't like the idea of regulatory discussions on this list. However, I am curious (as it's pertinent to what we do on this list) what the rules are in other counties for ham radio.. So far I haven't had much luck finding the answers on the web. Presently in US ham radio data bandwith: 2 meters is 20 khz max, 19.6 kilobauds 70 cm is 100 khz max, 56 kilobauds Ironically, while there is plenty of space on 70 cm, other modes like ATV are permitted to occupy up to 6 MHz of bandwidth. Since we have a nice mix of hams from all over the world on this list, I'd appreciated a reply (can be off list) on what is permitted in your country on 2 meters and 70 cm. Thanks, Steve, KB9MWR
