gsm7224 : at the end of my rope configuring ssh
I apologize for not selecting the correct "location" -- it won't let me select anything close to my model. Perhaps a moderator can put this post in the correct place. I am working with a gsm7442L...
Hi,
Sorry about this. I meant to write back in.
I have concluded that there are two possible problems here:
- Although the switch is supposed to support SSH 2, I suspect either that:
- It does not really support it
- It requires that, even if you have elected not use SSH 1, the presence of an SSH 1 key is required
- Alternatively, the nvram may be corrupted, and unfortunately there is no copy operation by which I could get back the key I downloaded and compare it with the one I have locally.
I looked into testing SSH 1 keys, but modern openssh just does not support it. I was unable to install an older version that would create SSH 1 keys.
I reached the point where the amount of time it was taking me to get this one to work exceeded its cost (it was pretty cheap on ebay -- I should have known there would be a catch), so I am returning it.
I ordered an M4100 to replace it. That one appears to date to circa 2015, so I hope that it will be relatively easier to get it working.
But this is all sketchy stuff and definitely not for the faint of heart. I have a cisco sg250-08 that I bought just a few years ago so it's pretty new. I had all manner of trouble getting ssh to work on it. The difference is that the ssh daemon starting was not dependent on the format of any keys (that is just a very poor design choice).. There were meaningful error messages. And the switch is new enough that I was able to find the solution using my google fu.
Thanks all for your replies. I do consider this a "solution": just don't given in to the sunken cost fallacy 🙂

No surprise given that this place is a rat's nest.
You might get more help, and find earlier questions and answers specific to your device, in the appropriate section for your hardware. That's probably here:
Discuss Ethernet Switches Plus and Pro Managed
You might like to search there for messages related to your problem.
I will ask the Netgear moderator to move your message.
In the meantime you could visit the support pages:
Support | NETGEAR
Feed in your model number and check the documentation for your hardware. Look at the label on the device for the model number.
Check for various troubleshooting tips.
You may have done this already. I can't tell from your message.
I mention it because Netgear stopped supplying printed manuals and CD versions some years ago and people sometimes miss the downloads.

Indeed 8-)
According the product documentation and downloads page https://www.netgear.com/support/product/gsm7224v1 Netgear does talk of the GSM7224v, a ProSAFE 24 Port Gigabit Managed Switch (dated from 2007).
This Managed Switches community section talking of Managed Switches Series including: M4100, M4200, M4250, M4300, M4500, M5300, M6100, M7100 was opened long before the area was generated.
Let's hope there is some related know-how and experience was left back here.
