Sudden SSH problems
I have had my ReadyNAS Pioneer Pro running for a couple of years with the EnableSSH add-on. Sometime in the past week I have lost the ability to ssh to the ReadyNAS. When attempting to SSH as root I g...
The ReadyNAS was not connected to an internet connected network so hacking is unlikely. (Network was a dumb switch connected to the NAS and to two Macs without internet connectivity.)
Repeated reinstalls of the OS from flash has not resolved the issue. However, I have noticed that the end of the /etc/sshd_config appears to be truncated in the zip file obtained when backing up the settings. I have also noticed that the shutdown and reboot operations via the web interface appear to work (in that the shutdown dialog is displayed and an entry is placed in the web log), but the NAS never shuts down.
I have pulled all the drives and factory reset the NAS with a fresh drive. After this factory reset the NAS was behaving correctly and would allow ssh access. So it would appear that the hardware is happy.
I have put the original drives back in the NAS, performed an OS reinstall and am working to copy the data off via NFS. Once I have the data backed up I plan to reset the NAS to factory defaults, build my volume with dual redundancy from the beginning, and then restore my data.
