I have a simple script that runs from a shared folder on a server.
When I run it from the same network where the server is, everything runs smooth, but when I'm not on the same network and I establish a VPN connection before running it, it returns an error message.
The script:
url = %1%
reservation = %2%
status = %3%
uid = %4%
ex_id = %5%
variables = {"id":"%reservation%", "status":"%status%", "uid":"%uid%",
"ex_id":"%ex_id%"}
WebRequest := ComObjCreate("WinHttp.WinHttpRequest.5.1")
WebRequest.Open("PUT", url, false)
WebRequest.setRequestHeader("Content-Type", "application/json")
WebRequest.Send(variables)
Return
The error is 0x80072726 - An invalid argument was supplied.
Specifically: Send
WebRequest.Send(variables)

Any help would be greatly appreciated because I'm stuck here.

I am trying to make a connection from a server running Ubuntu to a Beckhoff PLC with TwinCAT 3. With Windows everything works fine but with the same server on Linux I can't get a connection.
The Linux server has a static IP and in the route manager in the PLC I can find the route and see the server. I have tried adding the route by the route manager in the PLC and with "add_route_to_plc" but both ways my connection is refused. I have already turned off all firewalls. Any of you guys any idea what goes wrong here? In the attachment I have added some picture to see my settings and code that I try to run.
Python error: "connection closed by remote"
Python code:
import pyads
SENDER_AMS = '192.168.1.180.1.1'
PLC_IP = '192.168.1.100'
PLC_USERNAME = 'Administrator'
PLC_PASSWORD = '1'
ROUTE_NAME = 'GID_TEST_ROUTE'
HOSTNAME = 'Grid-stabilizer'
pyads.open_port()
pyads.set_local_address(SENDER_AMS)
pyads.add_route_to_plc(SENDER_AMS, HOSTNAME, PLC_IP, PLC_USERNAME, PLC_PASSWORD, route_name=ROUTE_NAME)
pyads.close_port()
plc=pyads.Connection('192.168.1.100.1.1', pyads.PORT_TC3PLC1)
plc.open()
plc.read_state()
If you are running python on linux and the plc on windows try
plc=pyads.Connection('192.168.1.100.1.1', pyads.PORT_TC3PLC1, PLC_IP)
This will create a route on the linux system. In your code the ip is missing to create a proper route.
Check the port of your plc. It should be 851.
I've created a script which sends messages using telethon. The receivers are not always the same: the number of receivers and their IDs are taken from a MySQL table. The multi processing script runs okay in the expected loop when started from the command prompt. But as soon as it's started as a service the messages are not send.
Please see the code below which includes the function to send out the messages. This function is called by another function which loops over the result of a MySQL query.
Can someone shine a light on the question why the function runs fine from the prompt and not as a service?
import configparser
# get configuration
config = configparser.ConfigParser()
config.read('/etc/p2000.cfg')
telegram_api_id = config.get('telegram','api_id')
telegram_api_hash = config.get('telegram','api_hash')
telegram_bot_name = config.get('telegram','bot_name')
client = TelegramClient(telegram_bot_name, telegram_api_id, telegram_api_hash)
def p2k_send_telegram(PeerID,Message):
async def main():
await client.send_message(int(PeerID), Message)
with client:
client.loop.run_until_complete(main())
Okay, the answer was easy and right in front of me! The issue could be isolated to the client variable. When running as a service under systemd the session (file) has to be defined with its full path!
Something like this:
client = TelegramClient('/full/path/to/my.session', telegram_api_id, telegram_api_hash)
I've developed a .Net console application to run as a webjob under Azure App Service.
This console app is using WinSCP to transfer files from App Service Filesystem to an on-prem FTP Server.
The connectivity between App Service & the on-perm FTP server is Okay.
Most of the time the job succeeds ,the files are synced, and log files written as well.
Sometimes, the job fails, no files synced, and no Log is NOT being written as well.
The Exception that is being fired intermittently on ALL of our Azure environments (Dev, Test, Prod):
WinSCP process terminated with exit code -1073741819 (C0000005). There was no output. Response log file D:\local\Temp\wscp550C.03E988EE.tmp was not created. This could indicate lack of write permissions to the log folder or problems starting WinSCP itself.
Any Clues ?
My code snippet ..
///Session Options
var sessionOptions = new SessionOptions
{
Protocol = Protocol.Sftp,
HostName = host,
UserName = userName,
Password = password,
SshHostKeyFingerprint = sshHostKeyFingerprint
};
///Opening Session & Sync Files
using (var session = new Session())
{
var timestmp = DateTime.Now.ToString("MMddyyyyHHmmss") + ".txt";
session.SessionLogPath = ConfigurationManager.AppSettings["SessionLogPath"] + timestmp;
session.XmlLogPath = ConfigurationManager.AppSettings["XmlLogPath"] + timestmp;
session.XmlLogPreserve = true;
session.FileTransferred += FileTransferred;
session.Open(sessionOptions);
var syncResult = session.SynchronizeDirectories(SynchronizationMode.Remote, localFolder, remoteFolder, false,false);
syncResult.Check();
}
WinSCP process terminated with exit code -1073741819 (C0000005). There was no output. Response log file D:\local\Temp\wscp550C.03E988EE.tmp was not created. This could indicate lack of write permissions to the log folder or problems starting WinSCP itself.
The error messages shows that you don’t give an write permission on production. Please give all write permission in Production Environment.
WinSCP could not create/write to log file that it uses to report back to the .NET assembly . Make sure your process has write permissions to the temporary folder. Alternatively, you can use (undocumented) property Session.XmlLogPath to change the log file location.
Refer here
C0000005 means "(memory) access violation". That probably indicates that WinSCP has crashed. It might mean a bug in WinSCP. Make sure you have the latest version. Otherwise, you better report this on WinSCP support forum, as software bugs do not really belong to Stack Overflow.
Got a trouble:
IBM MQ Server v9.1.0.0
pymqi==1.11.1
When trying connect to server got an error:
pymqi.MQMIError: MQI Error. Comp: 2, Reason 2035: FAILED: MQRC_NOT_AUTHORIZED
When I check traffic in Wireshark i got that:
And in server log this:
07/31/2020 10:08:02 AM - Process(27333.5) User(mqm) Program(amqrmppa)
Host(host) Installation(Installation1)
VRMF(9.1.0.0) QMgr(queue_manager)

AMQ9557E: Queue Manager User ID initialization failed for 'haha'.
EXPLANATION:
The call to initialize the User ID 'haha' failed with CompCode 2 and Reason
2035. If an MQCSP block was used, the User ID in the MQCSP block was ''.
ACTION:
Correct the error and try again.
My code sample:
import pymqi
host = "host"
port = 1416
conn_info = f"{host}({port})"
channel = "channel"
queue_manager = "queue_manager"
def main():
manager = pymqi.connect(queue_manager=queue_manager, channel=channel, conn_info=conn_info)
if __name__ == '__main__':
main()
I tried to execute the code from other devices and there, accordingly, the account under which I ran was taken as the UserID.
After that I asked our support to deal with the problem, after which I was able to connect with an account haha, but the solution with the creation of a list of allowed users does not suit me. Is there any way to control the UserID that is sent by pymqi?
UPD 04.08.2020
The support team said that the user phoenix was created on the IBM MQ server with the password 123456789, tried to send an MQSCP:
manager = pymqi.connect(queue_manager=queue_manager, channel=channel,
conn_info=conn_info, user="phoenix", password="123456789")
And got similar error MQRC_NOT_AUTHORIZED and server log contains error as above with username of machine where code launches (not phoenix).
We have been trying to use a SqlConnection within a TransactionScope. When we build the site and try this database call we run into an error:
A transport-level error has occurred when receiving results from the server. (provider: TCP Provider, error: 0 - An existing connection was forcibly closed by the remote host.)
The error involved occurs on the line cnn.Open().
using (var scope = new TransactionScope())
using (var cnn = new SqlConnection(connectionString))
{
cnn.Open();
int result = cnn.QuerySingle<int>("SELECT 1");
Console.WriteLine(result);
}
We created a console application to figure out what was wrong and discovered that by changing our connection string keyword 'Pooling' from 'false' to 'true' allows this to run in the console application and successfully return our result.
We made the same change to our site connection string, the same error as before returns.
Is there any reason this code is not working?
I was under the assumption that the web.config was law, as viewing the file through the Kudu service showed my expected connection string, but apparently this isn't the case in Azure.
I discovered that Azure Publish Profile is overriding our web.config connection string, this override still contained 'Pooling=false'.
Removing this now allows our code to run as intended.
This blog post explains more:
"When this code runs on a developer’s local machine, the value returned will be the one from the web.config file. However when this code runs in Windows Azure Web Sites, the value returned will instead be overridden with the value entered in the portal"
