Secure Shell for Google Chrome – REMOTE HOST IDENTIFICATION HAS CHANGED!

If you are using Secure Shell for Google Chrome and you change the IP address of a server to one that you used before :

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@    WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!     @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.
The fingerprint for the ECDSA key sent by the remote host is
c0:67:7b:9d:f5:4f:9d:57:43:44:67:7b:44:67:7b.
Please contact your system administrator.
Add correct host key in /.ssh/known_hosts to get rid of this message.
Offending ECDSA key in /.ssh/known_hosts:23
ECDSA host key for [test.host.local]:22 has changed and you have requested strict checking.
Host key verification failed.
NaCl plugin exited with status code 255.
(R)econnect, (C)hoose another connection, or E(x)it?

You will need to remove the known host from “/.ssh/known_hosts”.

You will use the command bellow in Ctrl+Shift+J ( Dev Tools ):

term_.command.removeKnownHostByIndex(HOST_NUMBER);

HOST_NUMBER is the one that appears in the error at :

Offending ECDSA key in /.ssh/known_hosts:23

Proxmox – Move Swap Partition from USB Boot Disk to another disk


First remove swap & partion
swapoff /dev/pve/swap
lvchange -a n /dev/pve/swap
lvremove /dev/pve/swap

Make swap file on another disk:
dd if=/dev/zero of=/pathondisk/swapfile bs=1024 count=2000000
chown root:root /pathondisk/swapfile
chmod 0600 /pathondisk/swapfile

mkswap /pathondisk/swapfile
swapon /pathondisk/swapfile

To activate /pathondisk/swapfile after Linux system reboot, add entry to /etc/fstab file.
nano /etc/fstab
/pathondisk/swapfile none swap sw 0 0

Save and close the file. After reboot, it enables the new swap file for you automatically.

To check swap is working:
free -m

Enabling Docker Remote API on Ubuntu


Edit the file /lib/systemd/system/docker.service
I used the nano editor:

sudo nano /lib/systemd/system/docker.service

Modify the line that starts with ExecStart to look like this:

ExecStart=/usr/bin/docker daemon -H fd:// -H tcp://0.0.0.0:2375

Save the modified file & restart Server

Test that the Docker API is indeed accessible:

curl http://localhost:2375/version

You should see output similar to this as the result:

{"Platform":{"Name":""},"Components":[{"Name":"Engine","Version":"17.12.1-ce","Details":{"ApiVersion":"1.35","Arch":"amd64","BuildTime":"2018-02-30T17:46:05.000000000+00:00","Experimental":"true","GitCommit":"4440fc6","GoVersion":"go1.10.1","KernelVersion":"4.15.0-32-generic","MinAPIVersion":"1.12","Os":"linux"}}],"Version":"17.12.1-ce","ApiVersion":"1.35","MinAPIVersion":"1.12","GitCommit":"4440fc6","GoVersion":"go1.10.1","Os":"linux","Arch":"amd64","KernelVersion":"4.15.0-32-generic","Experimental":true,"BuildTime":"2018-02-30T17:46:05.000000000+00:00"}
