[Blind-sysadmins] Re: Cisco NetAcad Labs - Packet Tracer accessibility

Hi Billy Thats interesting, how does GNS3 present the virtual image of a router OS? Is it contained within the program, so you have to use the GNS3 interface to interact with it, or does it create something similar to a VM, so some type of guest running on top of the host? If it was the latter, I imagine it wouldn’t be so simple as to just SSH into the guest? Thanks for all the advice. All the best Luke

Hi Luke,

Thanks for previous email. Adding to the discussion... Tshark will work if you get the physical lab. I even tried GNS3 which is a similar environment to Packet tracer. It too isn't accessible accept for it allows you to load up router images as virtual OS. You would still have issues getting the interfaces to talk I think. The biggest barriers I've faced is the idiots who think Blind/visually impaired person's aren't capable of much.

Best,

Billy

Hi Jackie

That’s really helpful info, thanks. Do you think I’d be able to use Wireshark in the context of the CCNA course though? The labs from Cisco are specifically designed for packet Tracer and I’m not sure whether I’d be allowed, even if it were possible, to convert the lab activities into alternative form that would make use of wireshark.

I’ll enquire about that, and see what happens.

All the best Luke

Let me amend my statement re: Packet Tracer. When I taught at CAVI--which has been a very long time ago now--it was not accessible. If they ever implemented changes since then to make it so, I am unaware, which says absolutely nothing. The tools I mentioned should help. Wireshark is pretty dicey accessibility wise, but its cli counterpart, TShark, should work well for you, & they have improved Wireshark's accessibility somewhat.

Hope you’re well.

I’m half way through a degree with the Open University and as part of that I am completing the CCNA course from Cisco.

This course includes using labs in the network simulator software Packet Tracer. sadly, as far as I can tell, this is a drag-and-drop interface and isn’t usable enough with a screen reader for me to complete the labs independently.

Does anyone know of a solution or work around to this? Has anyone ever done the CCNA before that can give me any advice? The NetAcad content itself is mostly fine, and in my opinion, works best with NVDA, it’s just the labs that are causing me problems. And of course, what with everything still be in virtual, I don’t think there is a possibility of me being able to physically complete the labs with Cisco equipment and instructors.

Thanks for any help you can give. Kind regards Luke
