SSL Labs is the effficient way to find which SSL protocols are enabled on your webserver.
Enter your website url and click on submit
https://www.ssllabs.com/ssltest/
It generated ssl scan report for your web application. You can check tls protocol enable/disable list.
If you want to scan tls protocol version on your local, Run following commands for different versions of tls.
tls 1 and tls 1.1 are vulnerable versions.
openssl s_client -connect app.localhost:443 -tls1
openssl s_client -connect app.localhost:443 -tls1_1
openssl s_client -connect app.localhost:443 -tls1_2
openssl s_client -connect app.localhost:443 -tls1_3
If tls 1 or tls 1.1 is enabled for your webserver but you are not getting results on command line, you need to make configuration changes in your openssl.cnf file.
Take backup of your /etc/ssl/openssl.cnf
sudo cp /etc/ssl/openssl.cnf /etc/ssl/openssl.cnf.bkup
Add this to the beginning of your config file /etc/ssl/openssl.cnf
openssl_conf = default_conf
And then this to the end:
[ default_conf ]
ssl_conf = ssl_sect
[ssl_sect]
system_default = system_default_sect
[system_default_sect]
MinProtocol = TLSv1.2
CipherString = DEFAULT:@SECLEVEL=1
Now export path
export OPENSSL_CONF=/etc/ssl/openssl.cnf
Now check again
openssl s_client -connect app.localhost:443 -tls1
openssl s_client -connect app.localhost:443 -tls1_1
Now it should show enabled tls protocols on command line
You can disable these protocols in your webserver config.
If you get the error ngcc not found but you have already installed all required angular packages.
To solve the issue, run command
npm install @angular/compiler-cli --save
If npm takes registry url attribute from global npmrc config file and not from the file which is in your home directory then you want to modify global config npmrc but you can not update as you do not have root privileges.
You can set local registry url for your npm commands.
npm config set registry https://registry.npmjs.org/
Now the url which is mentioned in global npmrc file will not be effective and it downloads package from this url only.
When you close the terminal and open new terminal, you need to run this command every time. To get rid off this, you need to add this command in your ~/.bashrc file, now whenever you open terminal, this command will be executed automatically in the background.
Create another config file from openssl configuration file.
sudo cp /usr/lib/ssl/openssl.cnf /etc/ssl/app.localhost.cnf
Now copy below code in the respective section of copied configuration file /etc/ssl/app.localhost.cnf
[ v3_ca ]
subjectKeyIdentifier=hash
authorityKeyIdentifier=keyid:always,issuer
basicConstraints = critical, CA:TRUE, pathlen:3
keyUsage = critical, cRLSign, keyCertSign

subjectAltName = @alt_names
[ alt_names ]
DNS.1 = app.localhost
DNS.2 = localhost
DNS.3 = app1.localhost
Uncomment line.
req_extensions = v3_req
Create CA Certificate :
openssl genrsa -aes256 -out ca.key.pem 2048
chmod 400 ca.key.pem
openssl req -new -x509 -subj "/CN=applocalhostca" -extensions v3_ca -days 3650 -key ca.key.pem -sha256 -out ca.pem -config /etc/ssl/app.localhost.cnf
openssl x509 -in ca.pem -text -noout
Create Server certificate signed by CA :
openssl genrsa -out app.localhost.key.pem 2048
openssl req -subj "/CN=app.localhost" -extensions v3_req -sha256 -new -key app.localhost.key.pem -out app.localhost.csr
openssl x509 -req -extensions v3_req -days 3650 -sha256 -in app.localhost.csr -CA ca.pem -CAkey ca.key.pem -CAcreateserial -out app.localhost.crt -extfile /etc/ssl/app.localhost.cnf
openssl x509 -in app.localhost.crt -text -noout
Now add ca.pem in chrome and firefox,
Chrome > privacy and security > security > manage certificates > authority
firefox > privacy and security > view certificates > authority
Use these crt and key in web server as ssl certificates.
Now open this virtualhost with https. Warning should not be appeared.
To get this, /usr/bin/sar should be installed. It is a default package.
cpu logs should be there in /var/log/sa folder in centos or redhat
If there is no /var/log/sa folder in ubuntu so the logs are stored in /var/log/sysstat. There is daily file of stored log.
usrname@hostname:~/Desktop$ ls /var/log/sysstat
sa09 sa10 sa11 sa12 sa13 sa14 sa15 sar09 sar10 sar11 sar13 sar14
You can find last 30 days logs here.

Steps :
sudo apt install libnss3-tools -y
wget https://github.com/FiloSottile/mkcert/releases/download/v1.4.3/mkcert-v1.4.3-linux-amd64
sudo cp mkcert-v1.4.3-linux-amd64 /usr/local/bin/mkcert
sudo chmod +x /usr/local/bin/mkcert
mkcert -install
Now use your virtualhost name in the below command instead of app.localhost. You can generate same certificate for multiple virtualhosts. Add multiple virtualhosts space separated in the below command.
mkcert app.localhost localhost 127.0.0.1
Use certificates in Apache ssl config, and restart Apache. Now open localhost and other virtualhosts in the browser. it should be secured.
Run an already trained model instance
git clone https://github.com/IBM/MAX-Text-Sentiment-Classifier.git
cd MAX-Text-Sentiment-Classifier
docker build -t max-text-sentiment-classifier .
docker run -it -p 5000:5000 max-text-sentiment-classifierIt will create a build in a docker container. We can check the application on port 5000.
http://localhost:5000
Open it by a domain / subdomain or it can be accessed by http://ip:5000
It will open a web interface. Since its model is already trained and it gives you output as positive and negative.
We need to pass the sentence and it will tell you, either the sentence is positive or negative. Once docker container is running, we can send the request using curl and collect the output in response.
curl -d "{ \"text\": [ \"The Model Asset Exchange is a crucial element of a developer's toolkit.\" ]}" -X POST "http://localhost:5000/model/predict" -H "Content-Type: application/json"
Response :

When you run logrotate command manually, it creates archived gz files successfully in the directory which you mentioned in the config file /etc/logrotate.d/custom-config but it does not run this command using daily cron automatically.
This is the most common problem of logrotate generally which you do not get in Ubuntu. Even if you want to run logrotate for your default log directory i.e. /var/log in Redhat or CentOS, you might not get this issue. You are getting this issue because you want to run logrotate automatically for your non-default directory like /opt/httpd/logs, /opt/odoo/logs or /opt/tomcat/logs etc.
Anacron runs logrotate using cron.daily. The issue is SELinux does not provide access to run logrotate using anacron for non-default log directories. It needs to mention explicitly to run logrotate for non default log directories.
There are two solutions of this issue.
Solution : 1
Do not depend on anacron. Create your own cron using root user. Log into the terminal using root user and set daily cron.
00 05 * * * /usr/sbin/logrotate -f /etc/logrotate.conf
Solution : 2
Set SELinux to run logrotate using anacron for non-default directories.
Follow this solution.
https://access.redhat.com/solutions/39006
Run commands as root user.
semanage fcontext -a -t var_log_t '/opt/httpd/logs(/.*)?'
cat /etc/selinux/targeted/contexts/files/file_contexts.local
restorecon -Frvv /opt/httpd/logsIt will solve your problem to run logrotate using cron automatically.

participants = results[i]
TypeError: 'ChannelParticipants' object is not subscriptable
Solution :
You are getting this error because group has more than 5k or 6K members, you need to provide limit in your python script.
all_participants = []
all_participants = client.get_participants(target_group, aggressive=False, limit=5000)
Now try again, you should be able to export members less than 5000.

If you are trying to deploy an android application on Genymotion Android Emulator and you are getting following error, this solution is for you.
An error occurred while deploying the file.
This probably means that the app contains ARM native code and your Genymotion device cannot run ARM instructions. You should either build your native code to x86 or install an ARM translation tool in your device.
1. First start Genymotion virtual Android Device and connect your Genymotion Android Device to adb. Follow this link
2. Once it is connected to adb, run command
adb shell getprop | grep ro.product.cpu.abi
3. It shows the list of architecture supported by the device.
4. Now how can you find the architecture of the app?
An apk is a compressed file, you can extract the content and open the lib directory. Here it lists the architecture as a folder supported by apk.
5. Now this apk has armeabi-v7a architecture which is not aupported by the device by default but Genymotion provides ARM translation packages as patch to install such apps on the device.
https://github.com/m9rco/Genymotion_ARM_Translation/tree/master/package
and download the package according to your android version of virtual device. Now drag and drop the apk in the device. Once this ARM translation package is installed successfully, turn off the device and reboot again.
If your device is not getting started, turn off the Genymotion software completely, kill all the processes related to it and VBox and start again.
7. Now once the device is started successfully, check the supported architecture by the device using same command.
8. If you are still getting same error
adb: failed to install h.apk: Failure [INSTALL_FAILED_NO_MATCHING_ABIS: Failed to extract native libraries, res=-113]
Your app architecture might be arm64 / arm64-v8a
Currently Genymotion Desktop do not support applications for aarch64/arm64, even with ARM translation tools.
However, they offer Genymotion Device (PaaS)
Android 8.0 (Oreo), 9.0 (Pie), 10 and 11 images which run on an ARM64
virtual machine at AWS and Oracle Cloud Infrastructure (only Android
8.0).
If you are trying to perform UPI transactions using icici bank app iMobile Pay and it does not allow to transfer money using UPI and you get following error
Mobile number and profile id does not belong to same user
This is the solution for you.
Solution : 1
1. Close the app. Update iMobile Pay from Google Play Store.
Open settings of your mobile and clear only cache of the app iMobile Pay.

You can try restarting your mobile too.
If you still get same error by touching any option of UPI like 'Send', 'Pay to Contact', 'Transaction History', 'Collect', 'Scan any QR' etc, Follow solution 2.
Solution : 2
1. Make sure your registered mobile number is active and you are able to send and receive sms.
2. Close the app iMobile Pay. Open settings and clear all data of the app iMobile Pay App.
3. Open the app iMobile App. Re register yourself on the app by selecting sim of your registered mobile no. (if dual sim).
4. Select your account number from drop down and confirm code of alphabets written at back side of your debit card.
5. Once you are registered successfully, Visit Section BHIM UPI in your app and try to open option 'Send','Pay to Contact', 'Transaction History', 'Collect', 'Scan any QR' etc
Now you should be able to transfer money using UPI
You can try restarting your mobile too.
If you are still facing same issue, write an email to customer care of icici on customer.care@icicibank.com or call them on their customer support number.

FloodWaitError - A wait of 30 seconds is required / Telegram Export Group Members more than 10000
aggressive=True attribute was used to export group members more than 10 K.
This attribute was used in the following line of code of Telegram export group members python script.
all_participants = client.get_participants(target_group, aggressive=True)But recently telethon has started giving FloodWait error with this attribute.
all_participants = client.get_participants(target_group, aggressive=False)
But Removing the attribute or making it false can export members of a group which has less than 10K members but it gives following error for the groups which have more than 10k members.
TypeError: 'ChannelParticipants' object is not subscriptablegithub page of this issue suggests a solution for the error. Upgrade your Telethon package to 1.24.0 using following command.

There are two conditions to Import / Export members of a telegram channel.
1) You should be an administrator or owner of the channel, then only you will be able to import or export members.
2) If a member has selected ‘My Contacts’ option in ‘who can add you to groups and channels’ then you should be added in his/her contact list only then you can import him/her in the channel.
To import channel members, First Generate api id and api hash in your telegram account. To do this, open my.telegram.org

Telegram Import Channel Members :
https://linuxamination.blogspot.com/2022/03/telegram-import-members-of-channel.html
There are two conditions to import group members of a telegram public group.
1) It should be a Public group but you do not need to be an administrator or owner of the group, You can import / export members of any public group, just you should be a member of the group.
2) If a member has selected ‘My Contacts’ option in ‘who can add you to groups and channels’ then you should be added in his/her contact list, only then you can import him/her into a group.
To import group members, First Generate api id and api hash in your telegram account. To do this open my.telegram.org
Login using your registered phone number.
Now Open Link Development Tools and copy your api id and hash
We will use the api id and hash in the Python Script
Create virtual environment with python 3 and install Telethon using pip.
virtualenv telegram -p /usr/bin/python3
source telegram/bin/activate
pip install Telethon==1.23.0
Update API ID, API hash and telegram registered phone number in the following python script import.py.

python import.py members.csv
Pass members.csv as an argument. It has all the exported group members. members.csv should be in same directory where you are running the script.
It will list all your public groups. Choose number of the channel into you want to import members. Members will be imported in the group.

Telegram Import Group Members :
https://linuxamination.blogspot.com/2022/04/telegram-import-members-of-public-group.html
Your export group python script was working fine but recently you tried to export members of one of your public group and it is showing following error.
telethon.errors.common.MultiError: ([None, FloodWaitError('A wait of 30 seconds is required (caused by GetParticipantsRequest)')Solution :
You need to make one change in your export script.
Remove
aggressive=True
from the line
all_participants = client.get_participants(target_group, aggressive=True)
Above line should be appeared like this
all_participants = client.get_participants(target_group)
and you will not get the following FloodWaitError anymore.

To see the steps :
1) Download existing code and database and put code into htdocs and import sql file or if it is new setup, follow this url.
https://framework.themosis.com/docs/2.0/installation/
2) If wp_options has different domain on production, Use same domain in virtualhost for local setup.
3) Point the domain upto htdocs (folder inside project root dir) and open it in browser.
4) If you get error
Unable to define the environment. / Unable to locate your environment configuration file. / Missing environment variables. / Error establishing a database connectionSolution :
<?php
return array(
'local' => ['xyz.local', 'xyz2.local'],
'staging' => 'dev.xyz.co.uk',

]
sudo chown -R apache:apache xyz.comIt is not able to create files in xyz.com/storage/views, that's why you are getting blank page once necessary files are created, site can be opened.
7) After doing all above things but still you get 'Error establishing a database connection'. Check if you have created wp-config.php inside cms folder.
This creation is the reason of database connection error. There should be only one wp-config.php and it is in xyz.com/htdocs/wp-config.php
wp-admin Details :
http://xyz.co.in/cms/wp-login.php8) Fix issue 'Error establishing a database connection' in existing setup.
Username - admin
Password - xxxxxxxxxxxxx
cd xyz.comRemove same domain from staging and production.
nano config/environment.php
nano .env.production.phpMake credentials and DB Variable correct.
rm htdocs/cms/wp-config.php
