Access locally hosted website from LAN?

I have a Ubuntu web server running locally on 192.168.0.x. I have port forwarded my public IP to to this local IP. I have configured my DNS servers to point to my public IP, and now the web server is accessible through domain example.com.

However, when I want to access example.com on a local computer on the network, it doesn't work. Of course, the server is always accessible through 192.168.0.x, but I need for it to be accessible through the domain.

Is there any way I could get this to work?

IPV4 address waiting list

Hi Redditor’s,

Giving that the ripe is running out of IPV4 address space, is there anyway that I can access the Non-allocated waiting to list to understand where I would be in the queue?

Any help and advice would be great!

Thanks in advance

Simulating connectivity issues

I work for a software company that wants the ability to simulate network errors. For example, we might want to block traffic on specific ports (eg 1883) for certain IP-addresses to test the system under different scenarios. We are testing a closed system so the "blocking-functionality" is only needed on one single LAN. No changes to incoming or outgoing traffic. Current gear is Unifi combined with some Cisco Firewalls.

How would you go about this? A completely separate piece of gear that developers can have unlimited access to? Any tips would be much appreciated!

Why is my flask website thats hosted on Virtualbox unreachable to other devices outside of network?

i made a flask website on the virtualbox Virtual machine that i can access on the virtual machine but on other computers i cannot access the website because it says "website is unreachable" ive tried many different ip addressess still nothing is working, any clues why and any solutions? maybe i have to do port forwarding? or i have to allow trafffic of a certain port coz its blocked? i dont know alot about networks.

Also whenever i run my flask website, i notice instead of running at "0.0.0.0" it runs at "10.0.2.15", which is strange coz i set it to run "0.0.0.0" in the code of the flask app, so coz its a virtual machine for some reason its running at "10.0.2.15" which i think is the guest ip address of the virtual machine so maybe thats why the website aint accessible outside the virtual machine.

Nornir multiple different task concurrency?

Nornir looks great for concurrently running the same command to your selection of inventory devices but what about having the same concurrency but with different tasks for each device? I take a stack of different tasks meant for different switches. Does that mean I'd have to implement threading on top of nornir tasks?

Example:

I want switch 192.168.150.10 to set port te0/0 - down and switch 192.168.150.20 to set port te0/7 up. Those are two different tasks that I would like to run concurrently.

Reliable repeater solutions?

So a client needs a solution for office/storage containers. There should be some sort of antenna or repeater, no big range required, which would be on the outstide (because of Faraday cage effect obviously), receiving an external Wifi network, and an internal part which would be repeating the network on the inside.

Also, the parts need to be very reliable. Price is no issue.

Any suggestions?

Router swap for transit peer

I've inherited responsibility for a small network that resells fiber connections for some local business and commercial customers. The previous network guy just up and left one day and cannot be contacted. Naturally, documentation is sparse. I've been tasked with cleaning up and rebuilding the network to prepare for a new hire or onboard.

My last task is to replace the core router, which advertises the local public network to the transit peer. I do not have access to this router nor do I have access to the account from the transit provider as the previous guy was the only person named. The company is working on that.

In the meantime, my plan is to replace the router with something I can access. I have enough information to mirror the BGP configuration to a new device, mostly. I was given the port IPs, peer IP/gateway, subnets.

I don't have the AS numbers for the local network or the peer listed. I've got the local AS from a quick WHOIS but the peer IP is a private address. If I do a WHOIS on the next hop IP, is it safe to assume that is the target AS?

Should I just wait until I can confirm the peering info with the ISP? I'm not really expecting that to happen any time soon.

***Seeking SFP+/QSFP/CFP2 EEPROM Programming Solution***

Seeking a solution for read/write EEPROM info to CFP2 devices.

So far I have only encountered solutions with DC powered boards and software that takes 20-30 min to perform a change on a single pluggable.

FWIW I also do a lot of SFP+/QSFP programming and currently use Elnec and find myself frequently longing for an easier solution. Even being able to copy/paste into the "view/edit" part of the software would greatly increase productivity!

Cisco SDA - Custom Config on Edge Node?

Hello folks,

We've got a site with a switch stack that's part of our SDA deployment, but only over a single 10G link. the second 10G link is on it's way, but is a few months away from being installed.

As a backup, we're looking at getting a 5G link to connect back to the VPN in the main site, but there's no way I can find in the SDA to make a backup link with a floating static, and the remote site is part of the shared address pool for the SDA.

Could I manually build a VRF and VLAN's on the Edge stack, so that in the event of the main 10G link dropping, I could move VLAN's manually (by going in over the VPN) and have the edge users connected to the new vrf and connect through the VPN.

Has anyone attempted anything like that? Will DNAC be rather upset that I've put that sort of config on an edge switch? Or will DNAC not care because it's not its config?

Best,

CC

Looking for a canadian supplier to replace CDW

It's taken over a week to get branded optics; like I couldn't get fs.com stuff tomorrow. Need Cisco, Dell, Arista, Fortinet, and Palo Alto (and Ubiquity, but let's not talk about that....) in a one stop shop, with access to vendor SE's on the table too. Softchoice comes to mind? Anyone else you want to recommend?
