distinguishing eBGP from show ip BGP
by Reza Motamedi 11 Mar '15

11 Mar '15

Hi Nanog, For a research I want to distinguish the external AS peering from "show ip BGP". In other words I want to see which entry show a path that immediately sends packets to another AS. My understanding is that *status code* shows if the route is internal, right? Does this mean if the *'i' *is not present, the route is goes out of the AS in the next hop. On the same note, can I use "Next Hop" to identify such entries? I just included a sample report from a public looking glass in XO. show ip bgp 207.108.0.0/15 longer-prefixes BGP table version is 529230540, local router ID is 65.106.7.145 * * *Status codes: s suppressed, d damped, h history, * valid, > best, i - internal, r RIB-failure, S Stale, m multipath, b backup-path, x best-external, f RT-Filter, a additional-path Origin codes: i - IGP, e - EGP, ? - incomplete Network Next Hop Metric LocPrf Weight Path * 207.108.0.0/15 216.156.2.164 3 0 2828 209 i * 65.106.7.101 2 0 2828 209 i * 65.106.7.246 3 0 2828 209 i * 65.106.7.55 3 0 2828 209 i *> 216.156.2.162 2 0 2828 209 i * 65.106.7.54 3 0 2828 209 i * 65.106.7.252 2 0 2828 209 i * 216.156.2.160 2 0 2828 209 i * 65.106.7.56 3 0 2828 209 i * 216.156.2.165 2 0 2828 209 i * 65.106.7.144 2 0 2828 209 i Best Regards Reza Motamedi (R.M) Graduate Research Fellow Oregon Network Research Group Computer and Information Science University of Oregon

Purpose of spoofed packets ???
by Matthew Huff 11 Mar '15

11 Mar '15

We recently got an abuse report of an IP address in our net range. However, that IP address isn't in use in our networks and the covering network is null routed, so no return traffic is possible. We have external BGP monitoring, so unless something very tricky is going on, we don't have part of our prefix hijacked. I assume the source address was spoofed, but this leads to my question. Since the person that submitted the report didn't mention a high packet rate (it was on ssh port 22), it doesn't look like some sort of SYN attack, but any OS fingerprinting or doorknob twisting wouldn't be useful from the attacker if the traffic doesn't return to them, so what gives? BTW, we are in the ARIN region, the report came out of the RIPE region. ---- Matthew Huff | 1 Manhattanville Rd Director of Operations | Purchase, NY 10577 OTA Management LLC | Phone: 914-460-4039 aim: matthewbhuff | Fax: 914-694-5669

Nmap has an option to "hide" your real IP among either a provides or IP list of IP addresses. " D *<**decoy1**>*[,*<**decoy2**>*][,ME][,...] (Cloak a scan with decoys) Causes a decoy scan to be performed, which makes it appear to the remote host that the host(s) you specify as decoys are scanning the target network too. Thus their IDS might report 5–10 port scans from unique IP addresses, but they won't know which IP was scanning them and which were innocent decoys. While this can be defeated through router path tracing, response-dropping, and other active mechanisms, it is generally an effective technique for hiding your IP address." http://nmap.org/book/man-bypass-firewalls-ids.html On 11 Mar 2015 02:17, "Steve Atkins" <steve(a)blighty.com> wrote: On Mar 10, 2015, at 4:40 PM, Matthew Huff <mhuff(a)ox.com> wrote: > We recently got an abuse report of an IP address in our net range.

Either the reporter doesn't know what they're talking about (common enough) or someone is scanning for open ssh ports, hiding their real IP address by burying it in a host of faked source addresses. That's a standard option on some of the stealthier port scanners, IIRC. Cheers, Steve

[Deadline Extended] IEEE International Workshop on Manageability and Security of Network Function Virtualization and Software Defined Network (MASONS)
by Chen Liu 11 Mar '15

11 Mar '15

--------------------------------------------------------------------------------------------------------------------------- Apologies for cross-postings! --------------------------------------------------------------------------------------------------------------------------- Call for Papers IEEE International Workshop on Manageability and Security of Network Function Virtualization and Software Defined Network (MASONS) With ICCCN 2015 at Las Vegas, Aug 3 – 6, 2015 http://www.icccn.org/icccn15/ MASONS 2015 is Technically Co-Sponsored by the IEEE Communication Society 1. Theme Today, many research organizations in academia, government labs and industry are exploring SDN and NFV technologies to study and materialize their benefits in real world networks. These benefits are enabling automation, reducing time to market in case of new service introductions, optimization and/or improving overall economics of network and system management and operations. However to materialize the benefits of SDN and NFV at larger scale across multiple domains, similar to today’s internet, additional investigations are needed which should focus beyond the core SDN, NFV features and functionalities. This involves: development of multi-domain SDN network to support Internet; large scale deployment of novel applications, identification of technological and operational gaps in research and development over the longer term to increase the capability of SDN and NFV powered networks, and better integrate them with existing public Internet and emerging cloud technologies; Identification of security, manageability gaps, including opportunities to build in additional levels of security, resilience and management capabilities. 2. Topics of interest This workshop aims to show case and disseminate new ideas and high quality research on manageability and security of Software Defined Network and Network Function Virtualization. We solicit original research articles, review papers, theoretical studies, and practical software systems incorporating new paradigms, experimental prototypes, and insightful requirement analysis with the above theme including, but not limited to the topics below: * Design, requirements and prototypes of Software Defined Exchanges (SDX) to enable interoperability and use of new approaches with the current Internet infrastructure. * Security, privacy, authentication, trust, verification for SDN and NFV. * Integration of compute, storage and network under the Software Defined Infrastructure (SDI) paradigm. * Analysis of new management challenges that SDN and NFV has introduced. * Network management practices and business processes for SDN and NFV, in service provider and data center infrastructures. * Tools and operational procedures for managing SDN. * New paradigms in network operations, administration and management (OAM), service orchestration, service engineering, converged network-compute and data center management. * Software Defined Network (SDN), abstraction, programmability, application Interface, south and northbound API. * Network Function Virtualization (NFV), distributed control, virtual switches, routing virtualization. * Network system management, orchestration, resource management and optimization, integration, interoperability. * Network operations management related automation, troubleshooting and management tools. * Cloud based network and system management application paradigms. * Application of artificial intelligence (AI), machine learning (ML), analytics and big data in network and system management. * Insights about Network Management System architectural requirements analysis. * Scalability of SDN, NFV, SDI, NMS systems. * User experience, user interface design issues and challenges in NMS for SDN, NFV, ethnographic studies on network operations centers, usability studies of management applications. 3. Speakers and Industry Panel * Morning keynote: Dr. Gee Rittenhouse, SVP, Cloud & Virtualization Group, Cisco System * Industry panel: Microsoft, IBM, Google, Cisco 4.
