Are underground utility markers essential workers?
by Sean Donelan 22 Apr '20

22 Apr '20

Utility markers don't get the recognition they deserve. If they aren't essential workers, they should be.... and get hazard pay. They help protect everyone's fiber and cables and pipes that go boom.

https://www.9news.com/article/news/local/fiber-line-damage-colorado-811-out… Construction crew hits underground fiber line, causes outage of 'call before you dig' hotline Through the 811 hotline you can call to have utility lines marked before doing any digging. DENVER — It looks like someone may have forgotten to call before they started digging and now others are unable to do so due to an outage of the Colorado 811 hotline caused by a busted fiber line. A message on the Colorado 811 website says there's an outage in the communication system. It says an underground fiber line was damaged and it's causing "significant" outages in the Denver area. Construction activity caused underground damage, according to the website. Crews are working to repair the damage, but repairs are not expected to be completed until around 8 p.m. Tuesday. [...]

Enforcement Bureau requests interested consortia to file Letters of Intent to conduct private traceback efforts pursuant to section 13(d) of the TRACED Act https://www.fcc.gov/document/eb-requests-letters-intent-traceback-consortium The Pallone-Thune Telephone Robocall Abuse Criminal Enforcement and Deterrence Act (TRACED Act) was signed into law on December 30, 2019. Congress required the Federal Communications Commission, not later than 90 days after that date, to “issue rules to establish a registration process for the registration of a single consortium that conducts private-led efforts to trace back the origin of suspected unlawful robocalls.” The Commission adopted rules to require any consortium that seeks to be selected as the single registered consortium to file a Letter of Intent to conduct private traceback efforts and directed the Enforcement Bureau to issue a public notice to that effect no later than April 28th each year.

Re: IS-IS Error (FRR)
by Mark Tinka 20 Apr '20

20 Apr '20

So we've been discussing this on Slack. It seems the packet handlers for IS-IS in FRR and how they work on FreeBSD is not completely optimized (not an issue on Linux). FRR-based IS-IS on FreeBSD is sending PSNP's that are 6,020 bytes large. However, FreeBSD's BPF (Berkeley Packet Filter) has a packet data limit of 4,096 bytes. This is what is causing the error. While it is possible to set the IIH MTU in FRR with the "lsp-mtu" command, there is not way to set the PSNP MTU. In short, IS-IS on FRR does not understand that there is an MTU limit for PSNP's on FreeBSD. I'm working with the IS-IS FRR team, but as of now, no idea on if/when there will be a fix for this. While routes are being successfully exchanged between FRR and Cisco IOS XE for IS-IS, this is a show-stopper! So for the moment, I cannot recommend anyone runs IS-IS on FRR in production. As it stands, it appears that this is the only thing standing in the way of a successful deployment, as far as simple Anycast services go. Will keep you all posted as this develops. Mark.

Constant Abuse Reports / Borderline Spamming from RiskIQ
by Kushal R. 19 Apr '20

19 Apr '20

From the past few months we have been receiving a constant stream of abuse reports from a company that calls themselves RiskIQ (RiskIQ.com) The problem isn’t the abuse reports themselves but the way they send them. We receive copies of the report, on our sales, billing, TECH-POCs and almost everything other email address of ours that is available publicly. It doesn’t end there, they even online on our website and start using our support live chat and as recently as tomorrow they I see that they have now started using Twitter (@riskiq_irt) to do the same. We understand these reports and deal with them as per our policies and timelines but this constant spamming by them from various channels is not appreciated. Does anyone have a similar experience with them?

IS-IS Error (FRR)
by Mark Tinka 18 Apr '20

18 Apr '20

Hi all. I'm almost there getting IS-IS to work without issue. I'm now faced with the following error log: 2020/04/17 10:02:01 ISIS: IS-IS bpf: could not transmit packet on em0: Input/output error 2020/04/17 10:02:01 ISIS: [EC 67108865] ISIS-Snp (1): Send L2 PSNP on em0 failed This repeats every second. Anyone know what this could be? Systems is FreeBSD-12.1-RELEASE-p3. Despite the error, IS-IS is running and routing is good, talking to a Cisco IOS XE implementation on the other side. So the error is throwing me off. No feedback from the Slack feed, Google doesn't say much, and waiting to hear back from the FRR list. Mark.
