Cron daemon error sudo /usr/local/vesta/bin/v-update-sys-que

[sanna]

Help me
I received this cron daemon error : sudo /usr/local/vesta/bin/v-update-sys-queue backup and
sudo /usr/local/vesta/bin/v-update-sys-rrd

sudo: parse error in /etc/sudoers near line 22
sudo: no valid sudoers sources found, quitting
sudo: unable to initialize policy plugin

I think after I use this because I had a bruteforce attack

thanks for support,
but if this file is corrupted, I cant access the Vesta CP ? With user Admin I have message : Invalid username or password.

I will try with VNC because with putty I cant access to root

[skurudo]

Sanna, why you can't connect as root?

but if this file is corrupted, I cant access the Vesta CP

Why is that? in sudoers you add some more permission to user.

Sanna, why you can't connect as root?

because I changed the port from 22 to another
I read here http://www.farinspace.com/secure-login-linux-server/
"Securing SSH Login
We will be using Public Key Authentication, so our first step will be to generate a public and private key. I recommend using PuTTYgen."
and now I cant access with putty : network error connection refused

but if this file is corrupted, I cant access the Vesta CP

Why is that? in sudoers you add some more permission to user.

With user Admin in Vesta CP I have message : Invalid username or password

[skurudo]

sanna, you can or not connect via ssh?

[sanna]

sanna, you can or not connect via ssh?

no I not connect via ssh
the only system is with VNC , right ?
many thanks

[skurudo]

Okey, vnc. But you can login as root?

[sanna]

Okey, vnc. But you can login as root?

no , invalid login or password incorrect

I ask to my VPS provider if I can do a rescue mode

[skurudo]

Try to ask provider and restore root password to your VPS.
