I have installed on Fedora 35 jfrog-artifactory-oss (v7.31.11-73111900.x86_64) and enabled it as a system service to start at boot. But whenever I boot up my OS, the server never starts properly. I will always need to kill the PID of the active running Artifactory process. If I then do sudo service artifactory restart it will bring up the server cleanly and everything is good. How can I avoid having to do this little dance? Is there something about OS boot up that is causing Artifactory to get thrown off?
I have looked at console.log when the server is not running properly after bootup, I see some logs like:
2022-01-27T08:35:38.383Z [shell] [INFO] [] [artifactoryManage.sh:69] [main] - Artifactory Tomcat already started
2022-01-27T08:35:43.084Z [jfac] [WARN] [d84d2d549b318495] [o.j.c.ExecutionUtils:165] [pool-9-thread-2] - Retry 900 Elapsed 7.56 minutes failed: Registration with router on URL http://localhost:8046 failed with error: UNAVAILABLE: io exception. Trying again
That shows that the server is not running properly, but doesn't give a clear idea of what to try next. Any suggestions?
2 things to check,
How is the artifactory.service file in the systemd directory
Whenever the OS is rebooted, what is the error seen in the logs, check all the logs.
Hint: From the warning shared, it seems that Router service is not able to start when OS is rebooted, so whenever OS is rebooted and issue comes up check the router-service.log for any errors/warnings.

I'm working on a project for deploying pentest lab with terraform & ansible. All is working good except that last problem.
In my lab I have a nginx server running on a Windows server. Nginx with php works when I start them as Administrator with ansible but i need them to run with a non admin local account.
For the php i've made a wrapper using this tools : https://github.com/antonioCoco/RunasCs
But it doesn't work with nginx cause of a working directory problem :
Here is the error :
PS C:\Users\Administrator> .\RunAsCs.exe nginx ***** C:\Web\nginx-1.19.6\nginx.exe
[*] Warning: GetUserProfileDirectory failed with error code: 2
[*] Warning: Unable to obtain environment for user 'nginx'.
[*] Warning: Environment of created process might be incorrect.
nginx: [alert] could not open error log file: CreateFile() "logs/error.log" failed (3: The system cannot find the path specified)
2021/03/06 10:18:33 [emerg] 5556#6124: CreateFile() "C:\Windows\system32/conf/nginx.conf" failed (3: The system cannot find the path specified)
And that's normal because as you can see my wrapper start in Windows/System32
I would like to know if there is a solution either with nginx.conf or with ansible to start this exe as the "nginx" user.
This is a working code for starting nginx as Administrator
- name: Starting web server
win_shell: .\nginx.exe
args:
chdir: C:\Web\nginx-1.19.6
async: 180
poll: 0
I know that there is a psexec module in ansible but psexec will work only for Local Admin account and the goal of that is that my nginx don't run as Local Admin.
Thanks for the help !

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
● postgresql.service - LSB: PostgreSQL RDBMS server

but when i try to connect to postgres through the default port with odoo it says:

Is the server running locally and accepting

after many searches i made i found the posgres main cluster is also inactive or down i tried to start it with this command
pg_ctlcluster 11 main start
but i get this error

and when i run the command as requested

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 having trouble with setting up Sentry server in HTTPS mode. Every now and then, reasonably often while seemingly random, this error message gets written by Raven (Sentry client) into log files:
Unable to reach Sentry log server: <urlopen error [Errno 8] _ssl.c:504: EOF occurred in violation of protocol> (url: https://$(valid_server)/)
Web UI works fine. Vast majority of the messages from Raven are received fine and Sentry processes them into usable output. However, due to these errors, something gets lost from time to time.
I have tried to figure this one out, but dead ends seem to follow another. Basically it seems a lot like this:
Python Requests requests.exceptions.SSLError: [Errno 8] _ssl.c:504: EOF occurred in violation of protocol
But when testing my Sentry server with similar s_client query using TLS 1.2, it leads to a valid session unlike with the example there.
It's also not about this, since SNI isn't used:
python-requests 2.0.0 - [Errno 8] _ssl.c:504: EOF occurred in violation of protocol
I'm not able to reproduce the error coherently. Raven's tests are passed and nothing is acutely wrong, until an error pops up in the log.
My set up is: Raven 4.2.1 in Python 2.7.5, Nginx 1.6.0 as reverse proxy handling HTTPS, and finally Sentry 6.4.4 with default Gunicorn 0.17.4. Nginx configs are pretty much similar to official documentation (http://sentry.readthedocs.org/en/latest/quickstart/nginx.html) with a few alterations due to HTTPS.
I ran into the same issue and got it fixed by installing the following dependencies:
On Ubuntu:
sudo aptitude install libffi-dev
And then via pip:
pip install pyopenssl ndg-httpsclient pyasn1
The problem seems to be that Python 2.X doesn't support SNI (which is needed for TLS) out of the box as explained here.
My requirement is to create a dump file of heap memory of a remote server using Jmap.
I did this way.
jmap -dump:file=remoteDump.txt,format=b 3104
This worked fine as 3104 is the pid of a process from my local machine.
How do I do the same with remote server?
I tried
jmap -dump:file=remoteDump.txt,format=b 3104 54.197.228.33:8080
But it's failed.
I tried creating a debug server using jsadebugd, as below.
1.Started rmiregistry
rmiregistry -J-Xbootclasspath/p:$JAVA_HOME/lib/sa-jdi.jar
2.Ran jsadebugd
>jsadebugd 11594 54.197.228.33:9009
But the step 2 is throwing the following error:

Help me get out of it.
The reason why you can not attach to process could be that it is already attached to some other debuger or executed on other visual machine than your jmap is running.
Try to assure that process is not attached to any debuger and you attach to the same VM.
