Tools and procedure for Network testing
by Joe Yabuki 26 Aug '21

26 Aug '21

Hi all, I just wanted to know how you do your network testing when validating a new design/technology in your Network, especially to ensure that it will meet your SLA requirements for example that a voice call will not be dropped in case of a network element failure ? Do you test with IXIA, multiping, launch somes VM using ping with -i option, Windows ping by setting the timeout interval, or may be directly from the Network device (routers...), Many thanks, Joe

Network Documentation Application Recommendations
by JoeSox 25 Aug '21

25 Aug '21

Hello, I first learned of NETDOT by Oregon State from this list but I have lost the prebuilt VM image I had on file and looks like the source code out on github doesn't compile anymore. So I liked how NETDOT was 1) Free 2) Created Topology image on the fly 3) Connected to network devices via SNMP to get version and interface details. Any NETDOT replacement recommendations? I have an https://www.networksecuritytoolkit.org box but not sure if any of the builtin apps can do it yet, I don't remember seeing one in the build but I may be missing it. -- Thank You, Joe

Newbie Questions: How-to monitor/control unauthorized uses of our IPs and DNS zones?
by Pirawat WATANAPONGSE 23 Aug '21

23 Aug '21

Dear Gurus, Background Information Part: We rent an IP Address Block and a DNS zone. [We have to pay the annual fees, so they are renting, yes? :-) ] We run our own DNS authoritative server, with DNSsec on. We register our IP block on both IRR and ROA, and monitor them both for ‘poisoning records’. Authority over DNS records, ROAs, and BGP table are with us, but authority over the Web Servers are (naturally) not. Question Part: 1. How (or where) can I monitor/control such that no one can ‘map’ my IP addresses to external FQDNs [hijacking my IPs] without me knowing about it? 1.1. My understanding is that, as long as I control the authoritative (DNSsec)server and people out there validate the DNS responses, hijacking my IPs outright for use somewhere else is (theoretically) impossible, yes? [leaving out Route Hijacking for now] 2. But, web admins can still essentially ‘rent out’ part or whole of my websites by hosting 'forreign' pages/codes and allowing in ‘external redirection’ from outside (to use my hardware! my IPs!) anyway, yes? 3. How (or where) can I monitor/control such that no one can ‘map’ FQDNs from within my DNS zone to external IP addresses [hijacking my hostnames] without me knowing about it? 3.1. My understanding is that, web admins can write all sorts of ‘redirect’ in such a way that parts or even my whole websites can be ‘hosted’ on external IPs/hardware, yes? 4. Does that mean I need a big Web Application Firewall (WAF) or something worse to monitor/control those above scenarios? The thing is, no one should be able to use organization resources [IPs, FQDNs, and Web Services, for a start] for his/her own purpose without asking permission. Thanks in advance for any pointers, -- Pirawat.

Setting sensible max-prefix limits
by Lars Prehn 22 Aug '21

22 Aug '21

As I understand by now, it is highly recommended to set a max-prefix limit for peering sessions. Yet, I can hardly find any recommendations on how to arrive at a sensible limit. I guess for long standing peers one could just eyeball it, e.g., current prefix count + some safety margin. How does that work for new peers? Do you negotiate/exchange sensible values whenever you establish a new session? Do you rely on PeeringDB (if available)? Do you apply default values to everyone except the big fishes? Apart from your peers, do you also apply a limit to your transit sessions? Best regards, Lars
