Cannot generate ssh key

[baggins]

Hi,

Strange problem.
After a reboot, a script that uses ssh to another server stopped working.
I found that the ssh key had disappeared from /lib/genohm-scada/storage.

I wanted to generate a new key with:

Code:

key = '/lib/genohm-scada/storage/id_rsa'
res = os.execute('dropbearkey -t rsa -f ' .. key)
log(res)
keyinfo = io.readproc('dropbearkey -y -f ' .. key)
log(keyinfo)

but no key is generated:

Code:

testing 07.05.2021 17:26:49
* string:
testing 07.05.2021 17:26:49
* number: 35584

Any idea what might be going on?
Thanks.
