    Packet Capture Documentation? Networking

    Packet Capture Documentation?

    Posted: 01 Nov 2020 08:56 AM PST

    Passing along. Here's a good book discussing the different packet capture techniques on Cisco devices.

    Anyone came across something similar for Juniper they can share?

    Infosec guy here looking to dip my toes into the ISP space because (to me) it's the most interesting industry I haven't done anything with yet. I've been at this for 20 years and know we can be a pain in the ass, what should I be thinking about now if I want to a) do my job AND b) let you do yours.

    Title pretty much covers it. I was an infosec consultant for 15 years and security architect at some pretty large companies for ~5 years. Have seen quite a few things in public and private sector, but have never worked for an ISP.

    Opportunity has recently surfaced at a carrier/ISP that I would like to take advantage of but would like to hear from folks that are in engineering/operations at ISPs today how your security team could be a net positive force in your daily grind. Assuming they have a job to do, what could they do less/more of to be effective while still letting you do your job.

    That's all. Thanks in advance!

    Switch Stacking or Router VRRP for Redundancy from Dual ISP

    Posted: 01 Nov 2020 10:20 AM PST

    Hi Reddit,

    ​

    Currently trying to design a network diagram that allows for two ISP's with full redundant/fault-tolerant setup.

    ​

    Current implementation is using two Dell OS10 switches that uses VLT, or I can use Switch stacking, and this way I can plug ISP1 into top Switch A, and ISP2 into bottom Switch B. That way if ISP 1, or Switch B fails, the network continues to operate on the redundant pair.

    I need to support two ISP's, two Routers or Switches for the ISP hand-off that feeds into two/dual Firewalls that support High Availability or active/passive fault tolerance.

    I want to know what is the optimal solution. Using dual routers and VRRP? Or switches that support stacking and utilize LAG to achieve redundancy.

    ​

    I need to support 50 users, hopefully this paints a better picture.

    ​

    tl;dr - Switch Stack with LAGs, or Dual Routers with VRRP? Need to have total fault tolerance and redundant network setup to ensure uptime.

    Interview help

    Posted: 01 Nov 2020 12:12 PM PST

    Hello,

    I am interviewing for an Consultant/Architect role in the coming weeks and I am looking for help as I have been at the same company my whole career that I am extremely nervous and dont know how to approach this.

    The job I believe is largely inline with my skillset but I am trying to figure out how an interview / technical interview will be structured and how do I prepare for this.

    My main fear is that I wont get across my skillset and project experience and just answer questions with short meaningless answers. Does anyone have any good advice for structuring an interview? Is there any resource where I could possibly listen to or watch back a real life interview?

    Sorry for the strange questions, but as I said, this is very new to me and I just dont know how to approach it...

    Looking to get WiFi across the street

    Posted: 01 Nov 2020 11:23 AM PST

    Hey all, apologies if this is not the right sub; I was referred here by r/homenetworking. Most of the other posts in this sub are a lot more technical than this one, so if I have the wrong place I would appreciate being pointed in the right direction.

    On to my issue - I work for a nature preserve and I have been tasked with getting wifi down to our parking lot from our office. After some research, it seems that an access point is what I need, but I have absolutely 0 experience with them and I don't know if they will do what I need them to do. I will list all of the relevant information I can think of below, but if you need any more info I am happy to provide it.

    • We currently have internet in our office building, but the office is about 200-350 feet away from the parking lot (depending on which end of the lot you are in). Ideally we want people at our map shelter (where we have the map of our trails and other information about the preserve) to have internet. This is about 350 feet away from the office building.

    • There is a road between the office and the parking lot, meaning that we cannot bury any lines across the road. The closest we could get would still leave us about 200+ feet away from the map shelter. This is going to be our biggest issue.

    • Our parking lot has a capacity of ~30 cars (and cars often park along the street when the lot is full, especially since COVID hit). With that being said, as this is the start of a 5 mile trail we will never have that many people trying to access the WiFi at once (unless we have a group hike scheduled, in which case we can just warn them ahead of time).

    • We do not need to support a bunch of people streaming or playing games or things like that -- we mostly need it so people can call an uber (there is 0 cell service in the area), check the map, and so staff can check emails and things on their phones from the lot.

    • There are some trees between the office and the parking lot, so line of sight isn't perfect. I can see the lot and most of the cars in it from the office, but there is a thin strip of forest between the office and the parking lot.

    • Price is a secondary concern, however it will certainly be considered. We likely don't want to spend $10,000 on an access point, but we would rather have something that is reliable and has a good range than save a few bucks.

    First of all, given the distance we need the wifi to travel, is an access point what we should be looking at or is there some other solution we should be considering? Based on the googling I did before posting it seemed like the only reasonable solution, but as I mentioned earlier, I am not experienced with them at all.

    Secondly, if an access point is what we need, do you have any suggestions? The first unit I was considering was this Engenius model, and another redditor recommended the UniFi HD. The UniFi HD seems like the better unit, and as long as my boss OKs the cost, that is the unit I am leaning towards.

    Thanks in advance for the help! Our hikers from next season also thank you!

    Configuring Azure Sonic on Celestica Seastone DX010

    Posted: 01 Nov 2020 10:58 AM PST

    Hi! I have Azure Sonic running on above hardware. I have installed Sonic on the hardware. However, I have no clue how to configure it. I am just ok with allowing all traffic from any ethernet port to ethernet port for testing. Then I would want to restrict all traffic but among two devices connected to two different eth ports. I would really appreciate if someone could help with it. I have checked GitHub but didn't really understand anything.
