Greetings, If someone from Intuit can contact me off list, I would highly appreciate it. We have a client that is not able to access QuickBooks Online from one of our specific IP blocks. The IP for https://qbo.intuit.com/ responds to ping, but any web request results in a connection timed out.

Catalyst 4500 listening on TCP 6154 on all interfaces
by frederic.jutzet＠sig-telecom.net 09 May '18

09 May '18

Hi, We have Cat 4500 series on SUP7L-E with IOS/XE 03.06.02.E/152(2).E2 which have TCP port 6154 listening on all interfaces. Any idea what it could be ? #show tcp brief all TCB Local Address Foreign Address (state) ... 5A529430 0.0.0.0.6154 <<<<<<<<<<<<<<<< #show tcp tcb 5A529430 Connection state is LISTEN, I/O status: 1, unread input bytes: 0 Connection is ECN Disabled, Mininum incoming TTL 0, Outgoing TTL 255 Local host: 0.0.0.0, Local port: 6154 Foreign host: UNKNOWN, Foreign port: 0 Connection tableid (VRF): 1 Maximum output segment queue size: 50 Enqueued packets for retransmit: 0, input: 0 mis-ordered: 0 (0 bytes) Event Timers (current time is 0xF58354): Timer Starts Wakeups Next Retrans 0 0 0x0 TimeWait 0 0 0x0 AckHold 0 0 0x0 SendWnd 0 0 0x0 KeepAlive 0 0 0x0 GiveUp 0 0 0x0 PmtuAger 0 0 0x0 DeadWait 0 0 0x0 Linger 0 0 0x0 ProcessQ 0 0 0x0 iss: 0 snduna: 0 sndnxt: 0 irs: 0 rcvnxt: 0 sndwnd: 0 scale: 0 maxrcvwnd: 4128 rcvwnd: 4128 scale: 0 delrcvwnd: 0 SRTT: 0 ms, RTTO: 2000 ms, RTV: 2000 ms, KRTT: 0 ms minRTT: 60000 ms, maxRTT: 0 ms, ACK hold: 200 ms uptime: 0 ms, Sent idletime: 0 ms, Receive idletime: 0 ms Status Flags: gen tcbs Option Flags: VRF id set, keepalive running, nagle, Reuse local address Retrans timeout IP Precedence value : 0 Datagrams (max data segment is 516 bytes): Rcvd: 0 (out of order: 0), with data: 0, total data bytes: 0 Sent: 0 (retransmit: 0, fastretransmit: 0, partialack: 0, Second Congestion: 0), with data: 0, total data bytes: 0 Packets received in fast path: 0, fast processed: 0, slow path: 0 fast lock acquisition failures: 0, slow path: 0 TCP Semaphore 0x5BEB9B10 FREE (The command "show control-plane host open-ports" is not available on this platform/code) I also think that if it would be a local socket for internal process communication, it would be 127.0.0.1:6154 instead of 0.0.0.0:6154. So this is listening on all interfaces, virtuals and physicals and seam not to be for internal internal process communication. Fred

REMINDER: Call for Participation -- ICANN DNSSEC Workshop at ICANN62 Panama City, Panama - June 25, 2018
by Jacques Latour 09 May '18

09 May '18

Hi All! ****Apologies there was some earlier problems with the mailing list so if you have submitted prior to today we may have not received the request. Would you please resubmit to the list and we will be sure to get a response to you as soon as possible? Thank you. **** The next ICANN DNSSEC Workshop will be on Monday, June 25, 2018 in Panama City, Panama. If you are interested in participating, please send a brief (1-2 sentence) description of your proposed presentation to dnssec-panamacity(a)isoc.org<mailto:dnssec-panamacity@isoc.org> by **18 May 2018** The committee is also thinking of having a panel on the Post-KSK-Rollover. We’d like to see if anyone from the DNSSEC community can identify ways that can help end users have a better idea of what they should look for and how they might be able to know if the KSK rollover has or has not effected them & their use of DNS (i.e. 1 second after the change). Thanks, Jack REMINDER: Call for Participation -- ICANN DNSSEC Workshop at ICANN62, Panama City, Panama. June 25, 2018 The DNSSEC Deployment Initiative and the Internet Society Deploy360 Programme, in cooperation with the ICANN Security and Stability Advisory Committee (SSAC), are planning a DNSSEC Workshop during the ICANN62 meeting held from 25-28 June 2018 in Panama City, Panama. The DNSSEC Workshop has been a part of ICANN meetings for several years and has provided a forum for both experienced and new people to meet, present and discuss current and future DNSSEC deployments. For reference, the most recent session was held at the ICANN Community Forum in San Juan, Puerto Rico on 14 March 2018. The presentations and transcripts are available at: https://61.schedule.icann.org/meetings/647563[61.schedule.icann.org]<https://urldefense.proofpoint.com/v2/url?u=https-3A__61.schedule.icann.org_…>,https://61.schedule.icann.org/meetings/647564[61.schedule.icann.org]<https://urldefense.proofpoint.com/v2/url?u=https-3A__61.schedule.icann.org_…>, and https://61.schedule.icann.org/meetings/647565[61.schedule.icann.org]<https://urldefense.proofpoint.com/v2/url?u=https-3A__61.schedule.icann.org_…>. The DNSSEC Workshop Program Committee is developing a 3-hour program. Proposals will be considered for the following topic areas and included if space permits. In addition, we welcome suggestions for additional topics either for inclusion in the ICANN62 workshop, or for consideration for future workshops. 1. DNSSEC Activities Panel (Regional and global) For this panel, we are seeking participation from those who have been involved in DNSSEC deployment in the region and also from those who have not deployed DNSSEC but who have a keen interest in the challenges and benefits of deployment, including Root Key Signing Key (KSK) Rollover activities. Now that DNSSEC has become an operational norm for many registries, registrars, and ISPs, what have we learned about how we manage DNSSEC? What is the best practice around key rollovers? How often do you review your disaster recovery procedures? Is there operational familiarity within your customer support teams? What operational statistics have we gathered about DNSSEC? Are there experiences being documented in the form of best practices, or something similar, for transfer of signed zones? If you have a specific concern about the Root Key Rollover, or believe you have a method or solution to help address impacts, we would like to hear from you. 2. DNSSEC Deployment Challenges The program committee is seeking input from those that are interested in implementation of DNSSEC but have general or particular concerns with DNSSEC. In particular, we are seeking input from individuals that would be willing to participate in a panel that would discuss questions of the nature: - Are there any policies directly or indirectly impeding your DNSSEC deployment? (RRR model, CDS/CDNSKEY automation) - What are your most significant concerns with DNSSEC, e.g., complexity, training, implementation, operation or something else? - What do you expect DNSSEC to do for you and what doesn't it do? - What do you see as the most important trade-offs with respect to doing or not doing DNSSEC? We are interested in presentations related to any aspect of DNSSEC such as zone signing, DNS response validation, applications use of DNSSEC, registry/registrar DNSSEC activities, etc. In addition, we welcome suggestions for additional topics. If you are interested in participating, please send a brief (1-2 sentence) description of your proposed presentation to dnssec-panamacity(a)isoc.org<mailto:dnssec-panamacity@isoc.org> by **Friday, 18 May 2018** Thank you, Kathy and Julie On behalf of the DNSSEC Workshop Program Committee: Mark Elkins, DNS/ZACR Jean Robert Hountomey, AfricaCERT Jacques Latour, .CA Xiaodong Lee, Chinese Academy of Sciences (CAS) Russ Mundy, Parsons Ondrej Filip, CZ.NIC Yoshiro Yoneya, JPRS Dan York, Internet Society

In response to feedback from operational security communities, CAIDA's source address validation measurement project (https://spoofer.caida.org) is automatically generating monthly reports of ASes originating prefixes in BGP for systems from which we received packets with a spoofed source address. We are publishing these reports to network and security operations lists in order to ensure this information reaches operational contacts in these ASes.

I saw that list, but understood the numbers there to be IDS signature numbers, rather than port numbers. Am I misreading something?

Is there a good Hulu contact for situations where IP addresses are being incorrectly flagged as anonymous proxy? I see 'ipadmin@hulu' but suspect that's not exactly what I need. Thanks, David. -- David Brain - MCNC - 919.248.1998

How are you configuring BFD timers?
by Jason Lixfeld 07 May '18

07 May '18

Hey, For those running BFD on your land-based point-to-point links, I’m interested in hearing about what factors you consider when deciding how to configure your timers and multiplier. On paper, BFD between two devices over a local or metro dark fibre or wave seems pretty trivial: Assuming your gear can a) support echo mode b) hardware offloads echo processing c) automatically treats echos as vital and puts them into the appropriate high priority queue, then setting the timers down to their lowest possible values (3ms on some of the gear that I’ve seen) and some low multiplier seems more than reasonable. But? From another angle, your link isn’t dark fibre or a wave but, for example, ethernet over some sort of IP based L2 Transport, and is still a low (sub 1ms) one-way latency local or metro link. How do you set your timers, and what do you base that on? From yet another angle, what if your link is a long-haul wave, or for that matter a wave of any distance that imposes a one-way latency that is higher than the minimum tx and rx timers that are supported by your gear? We’ll assume an unprotected wave, because I’m sure if it’s protected, you have no choice but to consider the one-way latency of the longest of the two segments. I made some assumptions above about support for echo mode and hardware offload, but what if (some of) your gear doesn’t support some or all of that stuff? How do you factor your configuration decisions? Thanks!
