[Solved] ssh stopped working (connection refused)

Try re-installing EnableRootSSH once more.

Are you remembering to connect as the 'root' user?

Done again got the

Successfully enabled root SSH access. The root password is now the same as your admin password.

in the log

but when accessing via putty on windows with the root user i still get "Network error: Connection refused"

I have even truned off the firewall and directly connceted to the readyNAS can ping and get tot fronview.

Can you try the suggestion here?: http://sphardy.com/web/readynas/restoring-ssh-access/

Downloaded file, restored to NAS and rebooted still get "Network error: Connection refused"

also nmap show's

PORT   STATE  SERVICE

22/tcp closed ssh

i don't think the ssh services is running or is failing to start or crashing

You probably better contact NetGear support (http://www.readynas.com/support). They might be able to tell from the logs what has happened and suggest a fix or remotely login and investigate.

thanks for the help.

i will try support but last time i had something like this i had to do a factory reinstall delete all my data. my photos and doc's are backed up elsewhere but reripping my music, movies and other media takes weeks.

OK did a Factory reinstall frimware 4.2.21 - all ok started putting files back
- installed enable root add-on
- rebooted got ssh access
- installed git via apt-get
- install plex add-on
- install python 2.7 add-on
- install sabnzbd add-on

rebooted all still ok -have ssh access
- still moving files on 2nd day
- setup couchpotato via git
- setup sickbeard via git
rebooted all still ok -have ssh access
- still moving files 3rd day
- have a play at building a couchpotato add-on
- do a few build with the add-on sdk -no install yet

- 4th day finshed moving files
- reboot and no ssh access
- yell and scream (other f'n 6 days moving files)
- try install frimware 4.2.19
- reboot got ssh access

will try updateing frimware when i get home and see what bracks...

ok some more info
- once logout out of ssh i then get the "connection refeused"
- doing a frimware update from file gives me ssh again (any frimware 4.2.19 - 4.2.21)
- logging out again breaks ssh (have to firmware reinstall)
- with a ssh session open first time i get connection refused on any other session
- googling and then looking at /var/log/auth.log with cat auth.log | grep ssh i get

- Googling and adding sshd to /var/run/ with mkdir sshd, chmod 0755 sshd
- I can open a 2nd session and reopen 1st session but i get

in the auth.log

do i need to do anything about "WARNING: /etc/ssh/moduli does not exist, using fixed modulus"??
i'll leave it for now and see how my ssh access goes on frimware 4.2.21

that didn't survive a reboot
- reinstalled firmware to get access back
- sshd missing from /var/run/ again
- 2nd session wont connect

- mkdir /var/run/sshd
- chmod 0755 /var/run/sshd
- 2nd session will connect again

- restart ssh with /etc/init.d/ssh restart
- error: ssh Could not load host key: /etc/ssh/ssh_host_dsa_key

- googled and found

ssh-keygen -t rsa1 -f /etc/ssh/ssh_host_rsa_key
ssh-keygen -t dsa -f /etc/ssh/ssh_host_dsa_key

- tried and is now working after reboot
- will give it a few days and see what happens. would like to know why these files go missing

ok been a few days and eveythings working think it's solved
