Scanning traffic; How much does the gateway get?

by Jeremy Cooper

Since taking on a BGP routed /24 several weeks ago I've occasionally watched my gateway firewall logs in realtime to get a sense of how much traffic I get from the Internet at large for my little section of the AMPRNet. I get an average of 2.7 packets a second in random scanning traffic. Scaling this up to the /8 that comprises AMPRNet, I surmise that the UCSD gateway must get something like 176k packets a second. Assuming an average SYN packet of 20 bytes, this is something like 283 gigabytes per day. Is that about right, Brian? -J

Re: [44net] Why if you are yahoo.com or gmail.com mail user, you probably won't see this message :-)

by Rob Janssen

> The subject line of this message is clearly wrong. > 255 of the 821 subscribers to this mailing list use @gmail.com > mailboxes. > If there were a problem with gmail, it would have shown up long > ago. I have a bit mixed feelings about it. As a coordinator I get regular mail from gmail users and often experience that my replies do not arrive or get marked as SPAM. I get reminders about requests that I have already processed, and sometimes a message "oh sorry I found your reply in the SPAM folder". At first I blamed my use of an @amsat.org address, and also using that address as a From: address in my replies. Due to the SPF record on amsat.org it can be expected that such use leads to marking of mail as suspicious. So I switched to using another alias service (@vrza.nl being offered by one of our amateur radio societies), but the situation did not improve. I still get reports of my mail ending up in the SPAM folder at gmail. But the vrza.nl domain has no SPF record. Apparently there is some relation to the user receiving the mail. Some users receive all my mail without problem, no matter if sent from @amsat.org @vrza.nl or another source. Others report that it is treated as SPAM for each of those. Not being a gmail.com user myself, I do not exactly know what features it offers for whitelisting or other special treatment of mail, or maybe what it learns automatically. It could be that sending back and forth several mails eventually leads to an address getting on the whitelist automatically. The same could be true for mail server IP addresses (like a mailinglist server), and it could be that knowledge built in the past also affects the results of new SPAM criteria added later. It is all a bit opaque, and when you want reliable and predictable mail service, using those mailservices certainly is not the best choice... or at the least check the SPAM folder regularly. (but I have also received reports of mail being dropped and not placed there) Rob

Why if you are yahoo.com or gmail.com mail user, you probably won't see this message :-)

by Neil Johnson

TL;DR: In never ending battle against SPAM and phishing attacks, some email providers are now using DMARC, rejecting or marking as SPAM email if the originating mail server doesn't match the authorized ones for the provider's service. For example: - Yahoo! is flat out rejecting e-mail from yahoo! mail users if it comes from non-authorized servers. - Google is marking e-mail from gmail users as SPAM if it comes from non-authorized servers. Unfortunately this breaks mailing list software like mailman (used for this list) which tries to make e-mail from the list appear as if it is coming from the original sender. The changes that are required to fix the issue change the functionality of the list software in ways users may not like. I found this out while applying DMARC for my my own domains. More info can be found at these sites: https://wiki.list.org/DEV/DMARC https://dmarc.org/ Fun. -Neil -- Neil Johnson

FYI - Amazon acquires 3.0.0.0/8 from GE

by Neil Johnson

https://news.ycombinator.com/item?id=18407173 Note: I'm NOT advocating anything like that for 44.0.0.0/8. It's just going to be fun to watch the market for IPv4 address space boom and then bust when IPv6 adoption finally reaches critical mass. -Neil, N0SFH -- Neil Johnson

Doing Gateway from Cellular Modem feed ?

by R P

Hi there Has someone tried doing A gateway with cellular modem ? I understand that cellular modems (at least in our country) do few times NAT (carrier-grade nat) and therefore the IP it get is not an IP accessible from the outside world so probably cant do any IPIP to the 44 net router Is that true ? or is there any solution ? We dont have IPV6 systems here yet which might overcome this problem only IPV4 any Info on the subject is appreciated Regards Ronen -4Z4ZQ http://www.ronen.org [http://www.ronen.org/My-QSl.jpg]<http://www.ronen.org/> Ronen Pinchooks (4Z4ZQ) WebSite<http://www.ronen.org/> ronen.org (Ronen Pinchooks (4Z4ZQ) WebSite) is hosted by domainavenue.com www.ronen.org

Re: [44net] Unregistered gateway?

by Rob Janssen

> Possibly a router not having updated the script to 3.2 after upgrade to > ROS 6.41 and later. Yes, that would be the reason for sending MNDP broadcasts. Actually I don't mind that those are sent, it can be useful as it provides the info I gave in the first post. But of course it would be nice when system->identity is changed e.g. to the callsign so it is easier to contact people when something is wrong. However, the main issue is that it is using a public IP that is not in the gateway list so these packets cause a log message and are dropped here. Likely the public IP has changed without the owner noticing it or without him realizing that he needs to update the portal entry. (of course this can be avoided when using a DNS name in the portal and some dynamic DNS update script, or even simply "IP Cloud" when this MikroTik is directly in the public IP) Rob

Unregistered gateway?

by Rob Janssen

Who is running an unregistered gateway at public IP address 72.192.178.228 ? (Cox communications) It is a MikroTik RB750Gr3 router running 6.42.6 firmware with default identity "MikroTik" broadcasting MNDP packets to all other gateways, apparently running Marius' ampr-rip script, but the address is not appearing in the portal. Maybe its address has changed but not updated in the portal? Rob
