Hi I’m looking for help and contacts for various connectivity options within Eswatini. Requirement is to have a minimum of two diverse operators. I haven’t ever deployed any connections in the country so would appreciate any references. Regards Ronald

Submarine cable root causation
by Ron B 08 Jun '24

08 Jun '24

The whole continent of Africa has connectivity dependant on a point 250km off Cote d’Ivoire and no causation about why this was deployed in this manner or how it’s been rectified. The immediate causation of rock falls doesn’t correlate to the terrain or repairs conducted. The canyon at Cote d’Ivoire is 20km across the continental shelf. The repair ships never entered this area. From the drop off on the shelf it has an offset starting 20km west that has been covered over by sedimentation flows during the past million years. Basically, from the continental shelf outwards the terrain is flat. The repair ships operated a further 20km east, from 100km out going as far out as 250km in a relatively straight line. Thus, about 40km east of the ancient remnants of the canyon. Although there are no route maps for the cables it seems SAT3 runs 100km parallel off the coast and WACS is at about 250km parallel off the coast. The Equiano cable is still further out but at what distance is unknown. This area has no similar flooding as the Congo where the river causes up to 1000km of high velocity flows off the coast. So why did this happen and why won’t it happen again?

Resilience
by Ron B 05 Jun '24

Maybe someone can help? Assume IP Transit A and IP Transit B. Ingesting routes from both. Transit B has a path failure but still advertises routes as preferable. They should stop advertising those routes but don’t. How does a person fix this cock up??? There should be an easier way than dropping Transit B until they fix their path.

Tik experts
by Ron B 04 Jun '24

04 Jun '24

Calling any Mikrotik experts I have a 30 AP site in Doornfontein that is desperately looking for a CAPSMAN implementation and troubleshooting. DM me for the details as I tapped out on this one. The disti referred someone but it didn’t work out. I’m certain there are people here who could do it with their eyes closed.

anyone know a suitable home for some WS-C2960S-24TS-L ?
by Nishal Goburdhan 27 May '24

27 May '24

does anyone know of a non-profit/community project/startup school something-something/blah that would want/ably use some WS-C2960S-24TS-L switches? (sorry, you homelab, does not count!). these are all in perfect working condition and were taken out of production, only because they are single-psu devices (and i hate the cisco RPS solution!). off-list responses welcome. —n.

FRR, IS-IS & unnumbered interfaces
by Hendrik Visage 16 May '24

16 May '24

Anybody else being as masochistic as I am to attempt using FRR's IS-IS with unnumbered interfaces? It works "like a charm" with IPv6, but IPv4 isn't routed if no IPv4 IPs on the IS-IS connected interfaces. Using Openfabric (based on and in the isisd code), it all just works... correctly (So why am I not using Openfabric? as I want to use it with multi node links/networks which Openfabric doesn't support/do, and I'm interested in interfacing with other network kit, so IS-IS is the beterer choice as openfabric is "dead" in IETF, replaced by the dist-opt-flood extensions to IS-IS) Though Openfabric will happily insert onlink routes on unnumbered interfaces, it seems that IS-IS "needs" to have an IPv4 address on the interface(s), else it doesn't have next hops to insert. I've searched high and low, and couldn't find any setting I've missed, and the source code hasn't been too helpful to see/understand if I'm missing something or if the needs haven't been coded into IS-IS yet. ``` Current configuration: !

by Yon Rosenthal 12 May '24

12 May '24

Hi We ran a zfs split to remove a drive from a 3 drive freebsd zfs mirror on our web server that hosts many client websites. The machine hung. We have not managed to get it up, even with trying to boot with each drive individually. The pool is unavailable. Is there a freebsd zfs expert who could please help us. We urgently need help. We will pay for their time. Thanks,
