I need login to manjaro from windows.
I found that on ubuntu or else xrdp is used, but not found on manjaro. sudo pacman -S xrdp wont work.
xrdp is in aur: https://aur.archlinux.org/packages/xrdp/
You could run for example yay -S xrdp
you can install remmina from snap store, no need to aur
sudo snap install remmina
Remmina supports multiple network protocols in an integrated and consistent user interface. and currently RDP, VNC, SPICE, NX, XDMCP, SSH and WWW are supported.
here is the link to snap store : snapstore/remmina

I have a running system with Ubuntu 16.04, Apache 2.4.18, PHP 7.3 and 7.4, PHP-FPM, PHP FastCGI, MPM event.
I wanted to upgrade to the latest Apache version (2.4.46-2+ubuntu16.04.1+deb.sury.org+3 amd64 [upgradable from: 2.4.18-2ubuntu3.17]) as follows:
add-apt-repository -y ppa:ondrej/apache2
apt update
apt-get --only-upgrade install apache2
service apache2 restart
Job for apache2.service failed because the control process exited with error code. See "systemctl status apache2.service" and "journalctl -xe" for details.
journalctl -xe
apachectl[9010]: [:crit] [pid 9013] (38)Function not implemented: AH00141: Could not initialize random number generator
I checked and /dev/random and /dev/urandom are installed.
Kernel: 4.4.0-042stab141.2 and libc6: 2.23-0ubuntu11.2
Happened to me after upgrading apache to version 2.4.46 on Ubuntu as well. I found out it was the kernel version.
I knew I did apt-get upgrade and the kernel should be latest version, Also running
sudo update-grub
Showed me newer versions, but running uname -r showed very old kernel.
After a long investigation that took almost all day and trying everything I found online about upgrading Ubuntu kernel - I found out it was Digitalocean, not me. Old droplets use external managed kernel - so no matter what you do on your environment, it will always take the external kernel. The solution was here:
https://www.digitalocean.com/docs/droplets/how-to/kernel/grubloader/#switch
If you do see the drop down & change button in your droplet settings in Digital ocean control panel, then your kernel is externally managed. In that drop down type “grub” and choose GrubLoader v0.2, press “change” button & that’s it!
Now you’ll need to shut down & turn back on your server, but before you do so I suggest to run the following commands:
sudo apt-get update
sudo apt-get upgrade
The above upgrade will update the whole system. To update just kernel run the above update command followed by:
sudo apt-get upgrade linux-image-generic
Now shut down (sudo poweroff or power off from DigitalOcean interface, though doing it from CLI is preferred). Note that reboot is not sufficient in this particular case and a complete shut down is needed (Thanks #gauss256 for your comment). Then power it back on from digital ocean interface, And upon startup you should see a new kernel version.
Tip - you might want to delete old Kernel files after the reboot, this can be done by:
sudo apt-get purge $( dpkg --list | grep -P -o "linux-image-\d\S+" | grep -v $(uname -r | grep -P -o ".+\d") )
Trying to get up my VPN interface with sudo wg-quick down wg0;sudo wg-quick up wg0 raised:
RTNETLINK answers: Operation not supported
Unable to access interface: Protocol not supported
I am not sure what happened but the only thing I did was reboot. I did not update my packages. Still something apparently changed.
In my case there were no appropriate kernel headers installed.
First you need to know your current kernel version:
# uname --kernel-release
4.19.0-14-cloud-amd64
Important part here is "cloud-amd64" (there are several versions of "linux-headers-..." package, use apt list linux-headers-* to see what is available).
Then install appropriate kernel headers (I'm using Debian):
# apt install linux-headers-cloud-amd64
Then re-install wireguard-dkms package:
# apt install --reinstall wireguard-dkms
Reboot your OS:
# reboot
In my case (Debian 10, PiVPN) i had to:
Install linux headers:
apt-get update
apt-get install linux-image-amd64 linux-headers-amd64
reboot
apt reinstall wireguard-dkms
reboot
Running apt update / upgrade revealed that there are wireguard updates available. Install those (you might have to reboot as well) and all will work fine again.
Secure boot as the internet suggests was a false trail in my case.
solution can be simple:
set in
[Interface]
MTU = 1412
to avoid packet limitations.
Done.
You may elaborate a smaller fitting size.
In my case it was enough:
sudo apt update
sudo apt upgrade
sudo reboot
Installed a new vmware player 15.5.1 on win10 pro, using guest linux/unbuntu 18.04 server
Trying to get to install the vmware tools (not sure what options I may have selected when I installed the work station). But the install vmware tools menu is disabled. When I run my VM get the re-install menu that too is disabled.
Tried manual install of vmware tools - but that also did not do the trick:
apt-get install open-vm-tools
apt-get install open-vm-tools-desktapop
systemctl status open-vm-tools
sudo shutdown -r now
ps | grep vmtoolsd
How do I fix this. (just start over with fresh install and all that or try use some other player (!?))
I did not get any response here and could not figure it out - tried many options. (same problem with VirtualBox)
But the good news, at least from cut-n-paste perspective- use alternate client. You can use ssh to login into the machine using your favorite tool - putty or even cmd will work. This actually is a better solution - no need to muck with mouse capture and all that.
So just setup a ssh server
sudo apt update
sudo apt install openssh-server
sudo systemctl status ssh
Active: active (running)
Open firewall
sudo ufw allow ssh
Check IP address
ip a
SSH in with PUtty or Cmd or ..
ssh username#ip_address
You are Done - will work like a charm
Note: This ssh works only from local host as the VM only has Pvt IP. If you can create public IP on VM (that is another arduous adventure - still working on it) - you will be able to remote ssh
I Try access pgAdmin4 via browser instaled in another Notebook with Linux Ubuntu 16.04 in the same network in my house, but not access.
In localhost... Ok
But REMOTELY... DOES NOT ACCESS
You need to add the following config options:
DEFAULT_SERVER = '0.0.0.0'
in config_local.py (in "pgAdmin4" folder).
If you also want to change the default port then also add
DEFAULT_SERVER_PORT = 5050
First change the line in config.py from DEFAULT_SERVER = '127.0.0.1' to DEFAULT_SERVER = '0.0.0.0'
Config.py is located in the same directory as pgAdmin4:
sudo find / -name "*pgAdmin4"
Start pgAdmin4 in the same directory (use tmux or as service to keep in background):
sudo python3 pgAdmin4.py
If you don't know the login, you can delete/move this file and restart pgAdmin.py:
sudo find / -name "*pgadmin4.db"
This should work on both Ubuntu Server and Desktop. You should preferably keep the 127.0.0.1 and use nginx or Apache in front.
Weird enough, in my case I have to manually run the command
$ pgadmin4
and then the dashboard will be presented in the default browser automatically.
It seems you are trying to open pgadmin client at server.
I suggest you to install pgadmin client from where you want to connect this , add server in pgadmin and do connect.
Tested on ubuntu 20.04
apt install pgadmin4-apache2
nano /usr/share/pgadmin4/web/config.py
Change 127.0.0.1 by 0.0.0.0
Don't forget to copy the key in the shell when you launch pgadmin4 in the remote web browser by replacing 127.0.0.1 by pgadmin4 host IP
E.G. : Something like this in your remote web-browser
http://192.168.1.56:43223/?key=5f45c8ee-4593-41d0-9ae1-06d6dd1d8280
PS : If you don't find config.py
apt install mlocate
updatedb
locate pgadmin4 | grep config.py$
All commands are in root don't forget sudo if you are not root
On macOS, I figured out that pgAdmin 4 web interface uses the port 61886.
Try to access it using http://localhost:61886/browser.
If not, run the command netstat -atp tcp | grep -i "listen" and check what ports are listening.
I need to monitor the performance of a raspberry PI (with raspbian), I tried to use new relic, but it doesn't support ARM architecture, so it's impossible to use.
I even tried graphdat but seems to have the same problem.
Any alternative to suggest me?
Linode Longview does support arm architecture:
https://www.linode.com/longview
The free tier have 12-hour retention but that may be enough for most cases.
I know this is old, but New Relic has ARM and ARM64 infrastructure agents now:
https://download.newrelic.com/infrastructure_agent/binaries/linux/arm/
I've tested this on a Raspberry Pi 4 (8GB) on Debian (32-bit) and it's been working fine so far.
In case anyone else tries, here's what I did:
Download the Infrastructure Agent:
sudo curl https://download.newrelic.com/infrastructure_agent/binaries/linux/arm/newrelic-infra_linux_1.20.5_arm.tar.gz --output newrelic-infra_linux_1.20.5_arm.tar.gz
Extract the files
sudo tar -xf newrelic-infra_linux_1.20.5_arm.tar.gz
Add license key to the config script:
echo "license_key=\"<YOUR_LICENSE_KEY>\"" | sudo tee -a ~/newrelic-infra/config_defaults.sh
Install the Infrastructure Agent
sudo ~/newrelic-infra/installer.sh
Check service status to make sure it's running:
sudo systemctl status newrelic-infra
By default, process information is not sent to New Relic, so I had to enable it manually:
echo "enable_process_metrics: true" | sudo tee -a /etc/newrelic-infra.yml
Finally, restart the service:
sudo systemctl restart newrelic-infra
