After understanding how to add an ospd scanner, verify it etc ...
I though I could finally use it but got an error through UI to add it to a task.
In my case, I run OpenVAS 9 on a debian 9 and I'm trying to include a w3af scanner but I got the same issue with every OSP scanner I add.
my pip freeze :
ospd==1.2.0
ospd-debsecan==1.2b1
ospd-nmap==1.0b1
ospd-w3af==1.0.0
Note that here is an example of w3af but the issue is the same for debsecan scanner and nmap scanner.
my openvas-check-setup :
Step 1: Checking OpenVAS Scanner ...
OK: OpenVAS Scanner is present in version 5.1.1.
OK: redis-server is present in version v=3.2.6.

To create the scanner in openvas, I use:
openvasmd --create-scanner="w3af" --scanner-host=127.0.0.1 --scanner-port=1235 --scanner-type="OSP" \
--scanner-ca-pub=/usr/local/var/lib/openvas/CA/cacert.pem \
--scanner-key-pub=/usr/local/var/lib/openvas/CA/clientcert.pem \
--scanner-key-priv=/usr/local/var/lib/openvas/private/CA/clientkey.pem
To run ospd-w3af scanner, I use:
~# ospd-w3af -b 127.0.0.1 -p 1235 -k \
/usr/local/var/lib/openvas/private/CA/clientkey.pem -c \
/usr/local/var/lib/openvas/CA/clientcert.pem --ca-file \
/usr/local/var/lib/openvas/CA/cacert.pem -L DEBUG
When I verify the scanner with openvasmd --verify-scanner xxxxx I got
Scanner version: 2018.8.22.
note: in the logs of the scanner I got this for every verify I do, I don't know if it's related or no and I didn't find a way to fix this:
2018-10-15 14:27:47,413 ospd.ospd: DEBUG: New connection from 127.0.0.1:60078
2018-10-15 14:27:49,430 ospd.ospd: DEBUG: Error: ('The read operation timed out',)
2018-10-15 14:27:49,433 ospd.ospd: DEBUG: 127.0.0.1:60078: Connection closed
So, my verification made, I want to create a task that uses this scanner but I can't save it due to error "Given scanner_type was invalid" :
https://i.stack.imgur.com/fvIJd.png
I got 0 connection to the chosen scanner at this moment and I can't find anything in the logs (maybe I can't search). I suspect the gsad UI being responsible for this but I can't find it.
I don't know what to do and if someone more expert than me (not very hard) could help that'd be great :)
Thanks in advance.
I solved this issue by creating a scan configuration for the ospd scanner (I though it didn't need one since it import them)
I faced another issue concerning ospd-w3af configuration, I couldn't create one because it needs ospd 1.0.0 installed, I modified the dependencies few days ago and it doesn't work with ospd 1.2.0
Now I'm facing the issue where the scans doesn't start properly. It stops at 1%
Getting openvas 9 running on new install of Ubuntu 18 was a pain. once i got past all my errors by creating files and ln -s for redis-server socks connections my tasks crapped out at 1%. My fix was install sudo apt install libopenvas-dev after that scans work and check-setup worked. Check-setup report no scanner but openvassd was running and openvasmd --verify-scanner (uuid) showed the scanner.

I was trying to install minishift on my local laptop.
I was following the below said steps as part of the process.
https://docs.okd.io/3.11/minishift/getting-started/preparing-to-install.html
Set up your virtualization environment
Download Minishift software for your operating system from the Minishift Releases page
Install Minishift

Configure Minishift so you can use it efficiently
I did install VirtualBox (6.1.16) as part of virtualization. And disabled the Hyper-v and Windows Hypervisor platform (Windows Program Features on/off). But after downloading and installing minishift by configuring it under PATH environment variable. I run the the below command - minishift start from command prompt.

Error starting the VM: Error creating the VM. Error with pre-create check: "This computer doesn't have VT-X/AMD-v enabled. Enabling it in the BIOS is mandatory"
I verified the BIOS Setup for VT-x/AMD-v, and it is enabled already, so I am wondering why it is still throwing this error -
This computer doesn't have VT-X/AMD-v enabled. Enabling it in the BIOS is mandatory
I used this commands cdk-scripts to verify that machine is capable of virtualization before running minishift on it. Should work for win 10 and 7.
Feel free to check the commands out on your machine. You will need powershell for that purpose.
To answer to my question here -
I uninstalled the existing virtual box and managed to run the minishift from windows hypervisor option (Hyper-v Manager). I adjusted my application processes (to control RAM usage) and launched minshift successfully using available 4GB RAM (out of total 8 GB in my machine).

I found
the same error question. This question discussed a my.conf file.
~/.my.conf did not exist on my mac
/etc/my.conf did not exist on my mac
this question teach me the my.conf location.
Finally I found my.conf in /usr/local/etc/my.cnf.Certainly the settings for mysqlx-bind-address were written in my.conf.
So rm /usr/local/etc/my.cnf, then brew reinstall SUCCESS!.
The permission was irrelevant at all.
this work for me:
rm /opt/homebrew/etc/my.cnf

I have a VPS hosting with a domain redirecting to it.
I have LAMP stack for my main website using WordPress CMS.
Plus I am using Odoo as my back-end with python and PostgreSQL in a sub-domain.
Everything was working fine until I installed Certbot Let’s Encrypt to obtain an SSL certificate by following these tutorials
For My Wordpress i installed this plugin:
WP Encryption – One Click single / wildcard Free SSL certificate & force HTTPS
Which got me in a loop because it forced the https i will explain it later on
So when the plugin didn't work i searched for another way for the whole VPS with these tutorials:
How To Secure Apache with Let's Encrypt on Ubuntu 16.04
How To Secure Apache with Let's Encrypt on Ubuntu 18.04
After completing the second tutorial for ubuntu 18.04 i noticed that all my domain traffic is going to https and it got stuck in a loop saying same as i said above
"ERR_TOO_MANY_REDIRECTS which means Site redirected too many times"
and couldn't access the website front-end for the wordpress in the doamin.
Then when i applied
"Step 3 — Allowing HTTPS Through the Firewall"
my internet connection got interpreted and when i got back to the ssh session i found my self locked out of the server and did not find any way to get back in.
And when i tired to use the sub-domain that has Odoo on it i have got the same error
"ERR_TOO_MANY_REDIRECTS which means Site redirected too many times"
Until here i was hopeless and did't know what to do.
I contacted my VPS server provider and told him about what exactly happened. Then some how he managed to get me into the server again with a URL to the terminal i still couldn't access the server using ssh clients like putty.. so when i entered the server after he provided me with the URL first thing noticed is that he "rebooted the VPS" will get to this in a second.
So first thing i did was removing the wordpress plugin "WP Encryption" and update the wordpress site-url in wp_options table in mysql database because the plugin changed it from http to https so i changed it back and that solved the ERR_TOO_MANY_REDIRECTS for my wordpress website.
Then the second thing i did was disabling the ufw firewall that i enabled in the tutorial in Step 3 above.
I instantly got my connection to the server back using ssh client putty but what i have noticed again is the postgres service was inactive and went down with the reboot of the VPS. i tried to start the service but it didn't a gave me this error.
Failed to start postgresql.service: Unit postgresql.service is masked.
i searched for a solution and found these commands to unmask
sudo systemctl unmask postgresql
sudo systemctl enable postgresql
sudo systemctl restart postgresql
and then the service has started and everything sames OK when i run the status command
service postgresql status
the response is

after many searches i made i found the posgres main cluster is also inactive or down i tried to start it with this command

but i get this error

I guessed Let's Encrypt added an ssl configuration to the pg_hba.conf and postgres.conf like id did with apache so i searched for them and commented the "ssl on" lines and restarted postgres service along with the main cluster but nothing happened still the the same error which is
Error: Could not find pg_ctl executable for version 11
I know i shouldn't run pg_ctl directly under Ubuntu/Debian. I must use pg_ctlcluster instead, which is installed by postgresql-common. I saw the main page documentation. But when i run "sudo pg_ctlcluster 11 main reload" command i always get the above Error telling me that he could not find pg_ctl executable
I have searched a lot for this problem but nothing worked how can i solve the pg_ctl executable in version 11 ??
Ps:
I am using Ubuntu 19.10 (GNU/Linux 5.3.0-24-generic x86_64)
Odoo 11 with postgres 11 as the database odoo can't connect to postgres as i mentioned before
edit:
Unfortunately i can't do a restore or recover the server to fix postgres package because my last backup of the server was on 19/3 and today is 26/3 i have an important data between this period
Update 27/3/2020 4:06 AM
I compared my last server backup with the production server and found a lot of postgres files missing!! like int this path /usr/lib/postgres/11/ and /etc/postgres/11/ i think postgres some how got damaged and lost some files in the reboot of the server >>> but found the data files of the database located in /var/lib/postgres/11/ <<< Can i read them in my backup server ? i will try and let you know
So finally after a hours of digging
All PostgreSQL files where damaged and missing and i lost hope of repairing them i don't know what caused that but it has a relation with the accidental reboot of the server.
So i managed to find the main cluster data file for my important database information for the production server in this path
/var/lib/postgres/11/
and i took a backup from it by zipping the whole folder using this command
zip -r main.zip main/
then i did a full purge and reinstall for postgres usuing these commands from here
apt-get --purge remove postgresql\*
to remove everything PostgreSQL from your system. Just purging the postgres package isn't enough since it's just an empty meta-package.
Once all PostgreSQL packages have been removed, run:
rm -r /etc/postgresql/
rm -r /etc/postgresql-common/
rm -r /var/lib/postgresql/
userdel -r postgres
groupdel postgres
Then i installed postgres with this command to match odoo11
sudo apt-get install postgresql libpq-dev -y
then creating the ODOO PostgreSQL User
sudo su - postgres -c "createuser -s odoo" 2> /dev/null || true
Now everything is okay odoo should work fine but you still don't have any database
So to bring back the backup from the cluster folder we took earlier we need to move the zip file to the same directory we took it from which is
/var/lib/postgres/11/
but before that you should stop postgres service
sudo systemctl stop postgresql
and make sure it has stopped
sudo systemctl status postgresql
after that rename the main cluster that postgres uses right now because its empty and we don't need it because we are replacing it with our backed up cluster
mv /var/lib/postgres/11/main /var/lib/postgres/11/main_old
then move the zip file from where you backed it up to the postgres cluster folder with this command
mv /backups/main.zip /var/lib/postgres/11/
unzip the folder in the same path by using this command
unzip -a /var/lib/postgres/11/main.zip
after unzipping the folder give the ownership to your postgres user and group
chown -R postgres:postgres main
Then you are good to go. Start Postgres service
sudo systemctl start postgresql
sudo systemctl status postgresql
and make sure you also start the main cluster service
pg_ctlcluster 11 main start
if you stopped odoo make sure to start it also
service odoo-server start
Ps: I solved ERR_TOO_MANY_REDIRECTS for the odoo sub-domain by commenting ssl configurations in my odoo.config Apache2 virtual host that lets encrypt updated before and everything got back to where left it before installing lets encrypt.
I guess i will leave it here and won't use ssl in production again till i figure out how to use it in a test server .. thanks for your time i hope my question and answer helps someone in the future
Try adding 'pg_path' in your odoo configuration file.
Like: pg_path = /path/to/postgresql/binaries
Generally '/usr/lib/posrgresql/11/bin' is the binary directory.
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
I have a new version of R installed on an aws-machine (which always come with an old version for some reason and it's near impossible to just have yum or apt-get to work). I want rstudio to point to this new version which I've built from source without throwing the old version away. I therefore go to /etc/rstudio/rserver.conf (documentation) and change the contents to:

What am I to do?
Below worked for me:
1) check the process that used 8787
sudo fuser 8787/tcp
2) with the -k option to kill all process.
sudo fuser -k 8787/tcp
3) Start RStudio Server
sudo rstudio-server start
The solution above is provided here by Leon Zhang.
The first thing to do is to check your configuration with:
rstudio-server verify-installation
a number of times when updating R or RStudio I have run into the same error as you have and get the following error message.
-bash-4.1$ sudo rstudio-server verify-installation
29 Sep 2015 18:24:11 [rserver] ERROR system error 98 (Address already in use); OCCURRED AT: rstudio::core::Error rstudio::core::http::initTcpIpAcceptor(rstudio::core::http::SocketAcceptorService<boost::asio::ip::tcp>&, const std::string&, const std::string&) /root/rstudio/src/cpp/core/include/core/http/TcpIpSocketUtils.hpp:103; LOGGED FROM: int main(int, char* const*) /root/rstudio/src/cpp/server/ServerMain.cpp:436
rstudio-server start/running, process 48632
Although I have never been able to figure out the cause, I can suggest the following workaround:
1. change the port /etc/rstudio/rserver.conf for example from 8787 to 8788
2. open the new ports in your firewall settings. (allow access to the new port in /etc/sysconfig/iptables)
3. update your firewall: sudo /sbin/service iptables restart
4. restart Rstudio server: sudo rstudio-server restart
This has worked for me each of the ~4-5 times this has happened. Although I am not 100% sure this can help with your use case, it may. As an alternative, if you can use containers in your AWS setup, you may be interested in a great off-the shelf docker image with the latest R/Rstudio.
It happened for me on my Cento-7.x machine while I upgraded from old RStudio server to the new version. Rebooting the machine seems to have fixed the problem.
