connx | A simple tcp server/client go framework | TCP library

I'm using a bash script to make changes to an SQL database. One of the values i'm updating uses dollar signs. The current value being something like "$$$$$" and i need to change it to "$$$$$$$$$$". However, a a $ in a bash script is used for variables.

How can i allow this small section of my bash script to used a $ as a normal character?

Current Situation : In my company we are using a windows server, in which we have installed Docker Quickstart Terminal. We have made a mysql-container and made a DB inside. We access the DB with python apps in remote pcs by using the server's IP in the code (host argument):

connx = mysql.connector.connect(user='root', password='somepass', host='192.XXX.XX.XX', port=3306, database='db_name', auth_plugin='mysql_native_password')

but we used port-forward in the server-side to access the dockerised DB, thus the packets are forwarded to 192.168.99.100 (default docker IP)

Future Situation: The company has decided to change the server and use Ubuntu instead (v18.04 i think). Unfortunately i have very little experience with linux and could not find a simple answer as the following online :

'Which IP should we use on the host argument above ?' Docker installation on linux does not seem to install a VM, so will the new server's IP be enough to access the dockerised IP remotely ?

PS : we will probably do a 'docker run -p 3306:3306 mysql:latest' command on the server to expose the ports

Currently Im facing problem in importing csv file to devexpress gridview,When i execute the code, the following error showed 'C:\New folder\QtimeAutomotiveByLot_new.csv' is not a valid path.

I want to connect to a WebSphere MQ Queue using SSL authentification from a PHP application (script).

• Queue Manager Version is 7.0 or 7.5
• MQ Client Version is 8.0
• PHP Version is 7.0 (docker)
• Using PHP mqseries pecl extension v0.15 (with custom fixes)

So far I was able to connect without SSL connection.

Here are the steps I have to done so far:

• I have installed the WebSphere MQ Client v8 for Linux (CentOS in my case)
• I have downloaded the PECL 0.15 version of the mqseries php extension. (There as a small bug in the extension, I had to recompile it to make it work properly. I used to get a segmentation fault on MQGET).
• I linked the the mqseries.so to php and enabled the extension.

I succesfully (without SSL)

1. Connect to the queue manager
2. Open the queue for reading
3. Get messages on the queue
4. Close the connection

When I set the USE_SSL in my script to true, I get the error code 2393 that means "An MQCONN or MQCONNX call was issued with SSL configuration options specified, but an error occurred during the initialization of the SSL environment." This error message is very generic and does not help me pin point where is the problem.

The MQ_KEYSTORE is set as /path/to/my/key and my filename is key.kdb and has at the same level key.sth as suggested by this documentation

The MQ_SSL_CIPHER_SPEC is the same in the script than specified by on the queue manager for the specified MQ_CHANNEL_SSL. Checked multiple times. These are NOT the Cipher Suite used with JMS connections

The security cache has been refreshed on the queue manager.

On the server side, I checked the error logs for the queue manager and didn't seem to see my channel name. I say "seem" because there was a lot of noise and there were a few ??? channel name in the lot. So I feel like it did not reach the queue manager for some reason.

I also used the "amqssslc" command found in the MQ Client installation bin folder to test my ssl config. I get the same error than using the PHP script.

I also used WireShark to sniff packets on the corresponding MQ_PORT. The content of the packages contained certificate information. So there is something that looks like a SSL hand shake going on.

I am now out of ideas as of how to debug the case. Does anyone has an idea of what to check next? Is there connection logs on my MQ Client installation that I should check?

Here is an example of a connection using SSL in PHP

Here is a simplified version of my MQ script (I removed the outputs). Some of the constants are not disclosed for security purposes.

All MQSERIES_* constants are defined in the extension

All MQ_* are hardcoded parameters to test my script but their definition does not appear in the script excerpt.

I'm new to PHP (just teaching myself) and have the following error in PHP but I cant get my head arround the problem:
