I am using Plone for my site When i am trying to run following command it gets an error :
Plone/zinstance $ bin/instance fg
Traceback (most recent call last):

ZConfig.ConfigurationError: There was a problem starting a server of type "HTTPServer". This may mean that your user does not have permission to bind to the port which the server is trying to use or the port may already be in use by another application. (Address already in use)
If you did not change the Plone configuration, it is trying to bind to port 8080. The error message indicates the port is already in use.
The most common reason is that this or another Plone instance is using the port. If you don't have another Plone install, then it may be the current Plone install, with the Plone daemon running as a background process. Try using bin/instance stop.
If that doesn't work and this is a development machine that you control, you may wish to simply reboot it. Otherwise, use your operating system's process-monitor mechanisms (ps aux | grep python on a Linux system) to find out if Plone is already running. If so, kill the process.
Plone is not the only package that uses 8080 as its default port. If the above has failed, use a network monitor program (netstat or sockstat on a Linux system) to track down the other process listening on the port. Change its configuration or Plone's.
sudo netstat -lnap | grep 8080
Check which process is using the port 8080 and use "kill " command to kill it and then again restart it.
I was facing the same error. I got some hint from this post http://plone.293351.n2.nabble.com/Address-Already-in-Use-error-td328781.html
I went to back to my command and seen that I was using wrong user in command with sudo.
sudo -u plone_daemon bin/instance fg --- Wrong command
sudo -u [Change_user_respectively] bin/instance fg -- It worked for me.

I created a Flask app that uses Beautiful Soup and Selenium to scrape and track Amazon product prices. The data was stored using CS50's version of SQLalchemy.
I then created an account to use Oracle's always free VM, with Ubuntu. I followed this excellent guide to the dot https://asdkazmi.medium.com/deploying-flask-app-with-wsgi-and-apache-server-on-ubuntu-20-04-396607e0e40f and set up Apache's conf file and the Wsgi file. I also added the network rules on Oracle's Virtual Cloud Network and to iptables, which I believe works fine.
Following this, the website still couldn't launch. Apache's error log showed a "PermissionError: [Errno 13] Permission denied: '/flask_session'". Based on this post Permission issue when writing file on webserver (flask, apache & wsgi) I changed the OS env to my env os.chdir('/home/ubuntu/flaskapp') and used chown to give rights
sudo chown -R ubuntu:www-data flaskapp
sudo chmod -R g+s flaskapp.
Now, my front page is accessible on http://129.150.38.171/ . However, upon any request to the server, Chrome displays "This page isn’t working 129.150.38.171 didn’t send any data." Apache's log shows a "segmentation fault (core dumped) python flask". Based on the sequence of my code, the error begins when I try to execute SQL, e.g. rows = usersdb.execute("SELECT * FROM users WHERE username = ?", request.form.get("username")).
I do not think that it is not my codes' error as it runs fine locally and the production server also worked when I set it up on Oracle VM using this guide https://docs.oracle.com/en-us/iaas/developer-tutorials/tutorials/flask-on-ubuntu/01oci-ubuntu-flask-summary.htm .
I've found this guide on debugging https://www.bustawin.com/debug-segmentation-faults-in-apache-from-mod_wsgi/ using gdb. But with source /etc/apache2/envvars
sudo -E gdb /usr/sbin/apache, it just tells me "No executable file specified".
Any ideas on what could be the error?
I'm just trying to do a POC test with Telium's HAAst before we offer it to a customer, but I've stalled before I start the haast daemon. Currently I have a single VM with Ubuntu 16.04 LTS with Digium's basic Asterisk 13 installation. I've configured haast.conf, it seems good, but I cannot start haast daemon, it stops after a few seconds. Here is the relevant log output:
General, HAAst version 2.3.2.1 starting as daemon under process ID 2409
Controller, Local peer HAAst state changing to service start
License, License file not found. Switching to Free Edition
General, Settings contained 0 information; 0 warning; and 0 error messages.
Asterisk Controller, Unable to located executable to control Asterisk
Controller, Local peer HAAst state changing to service stop
Controller, Stopped
General, HAAst terminating with exit code 158 (failure to find asterisk control files) after running for 2 seconds
It seems, haast misses the event controller to start Asterisk daemon, unfortunately it didn't contain the installation package. I've tried to make these files (asterisk.start & asterisk.stop) based on the other sample event files, I've set the executable bit, I've wrote the shebang to the first line based on the installation guide, but nothing helped.
Is somebody experienced about this case?
Thanks, Zsolt
This error means that High Availability for Asterisk (HAAst) is unable to find the service/executable file needed to control Asterisk. Since the 'distribution' setting in the [asterisk] stanza of the haast.conf file is it to 2 (Digium Asterisk), it means there's a problem with the Asterisk service file.
Ubuntu 16 uses systemd so have you installed Digium's asterisk.service (systemd) file? If you chose to install an initd service file for Asterisk instead then you may have to explicitly tell HAAst which to look for. If you installed neither then that's your problem. The maker of HAAst (Telium) has a support forum where this topic is addressed (click here).
The pre and post Asterisk event handlers are available in the commercial versions of HAAst only - so that won't help (but it's also the wrong way to solve the problem). There are also a few Ubuntu specific topics on the support forum https://www.telium.io/haast in case that helps.
If you can't find an Asterisk systemd service file here's a sample:
[Unit]
Description=Asterisk PBX and telephony daemon
Documentation=man:asterisk(8)
Wants=network.target
After=network.target
[Service]
Type=simple
User=asterisk
Group=asterisk
ExecStart=/usr/bin/asterisk -f -C /etc/asterisk/asterisk.conf
ExecStop=/usr/bin/asterisk -rx 'core stop now'
ExecReload=/usr/bin/asterisk -rx 'core reload'
[Install]
WantedBy=multi-user.target
Just save that file as 'asterisk.service' and place in /etc/systemd/system/ and ensure permissions match other service/unit files.
Haast configuration is missing or not correct:
Unable to located executable to control Asterisk
How can I stop the http server, downloaded using 'npm install http-server" comand in terminal (console) and launched then?
Simply Ctrl+C, if you read the output after you launch it, you should see:
Starting up http-server, serving xxx
Available on:
http://<some ip>:<some port>
Hit CTRL-C to stop the server
Its built on node so Kill the node process for stopping it if it stuck. You can find all the node process ids and see what I'd your server have and kill that.
I did an update on my opensuse box and networking stopped working. The system is trying to use networkmanager, even though it isn't installed. I am using yast to try and get it to use ifup, but it complains about no network connection. I tried running:
ifup eth0
and I get back:
Network is managed by '' -> skipping
Does anyone out there know why it is coming back empty and if there is a config file that I can manually tweak to fix this?
I'm assuming you are running 12.3 or 13.1 with systemd.
Disable network manager if it exists:
systemctl disable networkmanager.service
Enable network.service:
systemctl enable network.service
Make sure ifcfg-eth0 exists with a configuration in /etc/sysconfig/network/
Run ifup eth0
Hope this will help someone.
1. Disable NetworkManager, Stop is and then enable it and restart it respectively.
2. All this happens in console. Check the status for NetworkManager and in the status messages it should show that the interface(wierless) is disconnected. Confirm this by typing command "sudo nmcli c"
3. Type command "sudo iwlist (wireless-interface) scan" to show you the available wireless networks
4. If you see the network that you want to connect to listed, type command "nmcli a" and enter the corresponding connect phrase/password to connect
I have devstack installed on a ubuntu 12.04 and I could get logged into Dashboard , Now I changed the IP of my ubuntu machine. After changing the IP, I couldn't log into Dashboard anymore
I gets the following error message. I can see my old IP in the error message.

Is there a documented procedure available to change the IP address manually ?
My New IP doesn't have connection to internet so I wouldn't be able to redeploy devstack
Thanks guys for your answers..
I missed to update my answer, I fixed that issue in an easy way.
Solution is first run unstack.sh and then run stack.sh once more. It will do the necessary fix. Since I haven't made much progress with Devstack after installation it makes me more confident to run stack.sh
For the second time when you run stack.sh its not needed to connect to internet, So my issue is fixed.
Feel free to share your thoughts on this.
You will need to change the IP address hard-coded in OpenStack configuration files generated by devstack. They are stored in /etc/ and elsewhere.

Here's a few steps I've taken to get back online.
backup the answers file...
cp packstack-answers-20130417.txt packstack-answers.txt-SAVE
replace ip addresses...
sed -i '/s/10\.10\.248\.11/10\.32\.70\.10/g' packstack-answers-20130417.txt
Delete the cinder loopback devices, installer fails if it exists
losetup -d /dev/loop0
List what's left mounted via the loop.
losetup -a
rm /var/lib/cinder/cinder-volumes
Now rerun the deploy scripts
packstack --answer-file=packstack-answers-20130417.txt
Fix up other IP addressing concerns with nova-manage in the CLI.
Should work from here.
