My System : Windows 7 64-bit. While instaling Datastax Community Edition of cassandra,
As mentioned in the Prerequisites here :
http://www.datastax.com/documentation/gettingstarted/index.html#getting_started/gettingStartedWindows_t.html
I tried enabling SSL using instructions given here
http://www.datastax.com/docs/opscenter/configure/configure_ssl#config-ssl-win
but below is the error I get.
C:\>python "C:\Program Files\DataStax Community\opscenter\bin\setup.py"
File "C:\Program Files\DataStax Community\opscenter\bin\setup.py", line 51
print "Error when creating opscenter SSL files. Error was:\n"
^
SyntaxError: invalid syntax
What's wrong here?
What version of openssl did you install? That error is indicating the openssl command complained about a syntax error. OpsCenter specifically requires openssl 0.9.8 on windows.
http://www.datastax.com/docs/opscenter/configure/configure_ssl#enabling-ssl-windows
Edit the file create-file-pair.bat and set the variable OPENSSL_EXE to the path where your installation of OpenSSL is.

When I run xampp on fedora this error is showing up on application log
Starting Apache Web Server...
Exit code: 8
Stdout:
apache config test fails, aborting
Stderr:
httpd: Syntax error on line 522 of /opt/lampp/etc/httpd.conf: Syntax error on line 10 of /opt/lampp/etc/extra/httpd-xampp.conf: Cannot load modules/libphp7.so into server: libnsl.so.1: cannot open shared object file: No such file or directory
can anyone tell me how can I solve this?
it seems you're missing libnsl. install it through this command:
sudo dnf install libnsl
In case this doesn't work you can then download it manually:
Visit https://pkgs.org/
In the search box (pkgs.org of course) type libnsl.so.1 and choose the appropriate OS. The version shown might be higher e.g libnsl-2.28-9.fc29.x86_64.rpm, but it doesn't matter, the file needed is also included in this very package.
In the terminal, navigate to the directory where the .rpm was downloaded.
Type the following command to install it:
sudo rpm libnsl-2.XX-X.fc29.x86_64.rpm
Upon completion everything should be working fine.
A quick Google search returns this: https://www.reddit.com/r/Fedora/comments/8hlhlv/xampp_with_fedora_28/
The suggested fix is installing libnsl from this source:

I'm seeing the following error message when starting Spyder over a remote connection through MobaXTerm:
$ spyder
QXcbConnection: XCB error: 145 (Unknown), sequence: 171, resource id: 0, major code: 139 (Unknown), minor code: 20
Spyder still appears to work normally, but the error message pops up every time. A search on this error blames Qt5 and says there's no fix for X11 connections. I'm using Python 3.5.4, Spyder 3.2.3, and MobaXTerm Personal Edition v10.7 Build 3650 connecting to a system running RHEL 6.6.
How can I avoid the error message?
After trying the methods I could find on various websites:
conda install pyopengl on the base python installation
Adding both from OpenGL import GL and import ctypes; ctypes.CDLL("libGL.so.1", mode=ctypes.RTLD_GLOBAL) to site-packages/spyder/app/start.py
various Qt environment variable settings
EDIT:
I was finally able to stop the error messages by disabling only the "RANDR" MobaXTerm X11 extension:
Interestingly, the MobaXTerm documentation also has this extension disabled in the settings screenshots.
I ran into a similar issue when running rviz for ros2 from the Windows 10 WSL2 Ubuntu 20.10 Terminal with the command:
ros2 launch turtlebot3_bringup rviz2.launch.py
I tried unchecking the RANDR extension in MobaXterm to no effect. I was finally able to resolve the issue and launch rviz after issuing the following command:
export LIBGL_ALWAYS_INDIRECT=0
and then re-issuing the ros2 launch command above.
I downloaded the setup from official site and executed ./setup.py but got following error
File "./setup.py", line 54
print "Error when creating opscenter SSL files. Error was:\n"

SyntaxError: Missing parentheses in call to 'print'
any alternatives?
I am installing the ElastiCache Cluster Client for PHP on Red Hat 7.2 and centos 6.5 Amazon AMI , but issue still same on all.

after install elastcache cluster cleint for php i got this error
php -v
PHP Warning: PHP Startup: Unable to load dynamic library '/etc/php/lib/php/extensions/no-debug-non-zts-20131226/amazon-elasticache-cluster- client.so' - libsasl2.so.2: cannot open shared object file: No such file or directory in Unknown on line 0
PHP 5.6.15 (cli)
i have installed php by compiling/configure.
please let me know how to get out from this error, i tried everything but issue still same.
On some systems, notably CentOS7 and Red Hat Enterprise Linux (RHEL) 7.1, libsasl2.so.3 has replaced libsasl2.so.2. On those systems, when you load the ElastiCache cluster client, it attempts and fails to find and load libsasl2.so.2. To resolve this issue, create a symbolic link to libsasl2.so.3 so that when the client attempts to load libsasl2.so.2, it is redirected to libsasl2.so.3. The following code creates this symbolic link.
cd /usr/lib64
sudo ln libsasl2.so.3 libsasl2.so.2

I am using Ubuntu 12.04 LTS, and Apache 2.4.
I've installed TLS by following the steps on this link: https://help.ubuntu.com/community/GnuTLS
When restarting Apache I get the following error:
apache2: Syntax error on line 212 of /etc/apache2/apache2.conf:
Syntax error on line 1 of /etc/apache2/mods-enabled/gnutls.load:
Cannot load /usr/lib/apache2/modules/mod_gnutls.so into server:
/usr/lib/apache2/modules/mod_gnutls.so: undefined symbol: unixd_config
If I remove the #gnutls.conf file from the /etc/apache2/mods-enabled directory Apache restarts.
What is causing the module not to load?
Your level of mod_gnutls isn't aware of Apache 2.4, one breaking change in 2.4 is the symbol unixd_config is replaced by ap_unixd_config. There will probably be a slew of similar issues.
