  • lag bolts into shields into concrete may be secure if its done really carefully. it still leaves possible issues with the frame integrity - there are quite a few low quality frames and cabinets out there and mechanical stress on those vertical rails and all of the connection points in-between when equipment is extended on rails is no joke.

    I am used to datacentre grade mounting gear (even in my home lab), so I am a bit spoiled. however… take a look at Rack Solutions for harder-to-find quality mounts, rails and adapters. a source for excellent quality steel open racks/frames and enclosures is x-mark (now owned by belden). thats the stuff I use for myself.

    edit: as was mentioned in another comment, OEM rails are almost always your best bet, however high quality 4-post sliding shelves have saved my butt on ocassion. Rack Solutions also offers those.



  • thanks for the excellent reply. will check out all of your links.

    I do like built-in light weight threading, so Go is still on the to-play-with list and I am currently tracking a few Go projects to get my feet wet.

    you have given me options and impetus to get out of my decades long rut and, honestly, that is the best gift any programmer can give to another. thank you, friend.


  • thanks for the reply. C++ never really clicked for me. I started out decades ago with C and enjoyed living on the edge with older hardware and OSes - when neither the OS nor the hardware will defend itself from an application, things get real fun, real fast.

    as PC hardware matured, python filled in the safety spaces when needed and I eventually just used python with C bindings to balance speed and safety as needed for any particular project.

    I have never seriously looked at ada, but your comment piqued my interest, so I may just play with it for a bit. Go… what can I say about Go… like C++ its just feels “odd” to me. cant really explain why, perhaps it just feels too… “google”?

    I am going to be taking some time to really try groking Rust over the next 6 months… from what I have seen so far, Rust is the language that I wanted C++ to be so many years ago… fills in many more gaps and gives an expansive playground for various types of projects - many of the benefits of python-like and C-like languages in a nice, unified space.

    would love to get your thoughts on that if you have time.





  • if two devices in the same LAN have the same IP address, the sending host or switch gets confused and tries to sent packets to the wrong receiving device. this can cause long periods where devices seem to “drop off” the network, or only get some of the packets they are expecting.

    if you have no issues with device-to- device connectivity (e.g. large, long lived files transfers between your PCs are fine), then its likely not the problem.


  • is your ISP double NATing you? specifcally, are they providing a public IP address to your EdgeRouter? ISPs will often provide a residential router/modem combo and their router will distribute a private IP to your router - a double NAT. double NAT is usually not a huge issue, but its not nice to live behind one. if the ISP confirms that their equipment is bridging (and not routing), then the double NAT issue goes away.

    all of the symptoms you describe sound like intermittent packet loss and there are lots of possible reasons for this including poor signalling from your ISP and misconfigured routers (possibly your ISP customer premesis equipment)

    as long as your have verified good LAN cabling, including the ISP CPE to your router (you indicated a switch to GigE+ speeds - that needs good copper), the fact that you get this possible packet loss from devices behind your router but not between your router and the ISP CPE may mean your router and the ISP CPE are not playing well together due to double NAT.

    hope that helps.
