I have a virtual Linux server,
that failed to boot because a disk is not connected.
But it is just for the backups, so nothing critical on it.
Why can't it boot and just warn me.
Problem is, because it doesn't do a full boot. I can't ssh to it.

Supper exactly, what I needed.

Is there a command to test the hard disk speed ?

I got a problem with my swap space.

I got a small server with 1Gb ram.
It is getting to its limit.
It want to swap out memory but because there is no partition for swap,
so it is killing some processes.

How can i fix this, without adding a partition ?

I have a problem with openVPN.

My certificates can't connect.

In the log of the server, I got: Anyone know what the cause is ?

Is there an easy way to scan the network for all computers?
like ping, but not do all the 254 ip's by hand ?

I found the problem.
I sued the same key for server and client,
in the config of server and client (ta.key).

But the key was updated on the server,
and not in the client ovpn-file.

Put it in the ovpn-file,
send it to the client and it was ok.

Hello,

I have a problem with connecting my client with my openvpn server.
got the error:
Authenticate/Decrypt packet error: packet HMAC authentication failed

after a few tries,
I found another errors message :

Hi,

how do I change the ntp server on which my pc is synced ?
I have Debian / Ubuntu.
I searched for /etc/ntp.conf (was on my old linux)
couldn't find it.
