I've created my own private torrent file, and I'm testing it on another PC with it's own completely separate internet connection, but it gets stuck on status 'connecting to peers' and nothing downloads.
Here's what I did in creating my private torrent file,
Enabled 'bt.enable_tracker' and reset BitTorrent.
Check port and checked that it's open.
Created new torrent and inserted the following trackers,
http://External-IP:Port-Number/announce
http://localhost:Port-Number/announce
(of course replacing 'External-IP' and 'Port-Number' with my own).
Ticked 'Start seeding' and created torrent file.
Torrent file is now present on host PC.
Opened torrent file on second PC, but this is where it gets stuck on status 'connecting to peers'. For http://External-IP:Port-Number/announce - the status is HTTP Error 401. For http://localhost:Port-Number/announce, the status is invalid info hash and/or peer id. Where should i get the username and password from for the embedded bittorrent tracker?
I've also tried connecting via a third PC on the same LAN, but it gets stuck with the same status.
All other torrents, public and private site trackers download and seed just fine.
Any ideas where I am going wrong please?
Thank you

An instance of a BizTalk send pipeline has started to run continuously. On 09/12/2021 an attempt was made to send a file via SFTP, which retried several times but ultimately failed due to a network issue. The error from the event logs is:
The adapter failed to transmit message going to send port "Deliver Outgoing - SFTP" with URL "sftp://xxx.xxxxxx.co.nz:22/To_****/%SourceFileName%". It will be retransmitted after the retry interval specified for this Send Port. Details:"WinSCP.SessionRemoteException: Network error: Software caused connection abort.
For some reason BizTalk made another send attempt at 1:49pm on 10/12/2021 which succeeded as confirmed by the administrator of the SFTP site. Despite this, BizTalk continued making intermittent send attempts and the pipeline instance is still running. The same file has been sent 4 times to the SFTP server.
The pipeline instance in theory should have suspended at 9:47pm on 09/12/2021. I have been able to confirm definitively whether anybody resumed it, but it seems unlikely at this stage. In any case, after sending successfully the pipeline instance should have terminated and should not be re-executing intermittently.
Does anybody know what could account for this behaviour? This is occurring on BTS2020 with CU2 applied.
I've sent messages over SFTP where the WinSCP interpretation of the date-modified attribute doesn't work with a specific type of SFTP server.
With the WinSCP GUI a dialogue box appears and you can disregard this error, but this option isn't available with BizTalk's GUI. This error appears when a file with the same filename already exists on the server and is supposed to be overwritten.
My solution was to create a pipeline component that removed %SourceFileName% on the server. The pipeline component (just like WinSCP GUI) can disregard the modified-date.
I have a VPN configured by ovpn in my mikrotik that already works, but whenever I connect both by android and Windows, I get the error:
ovpn,debug,error,,,,,,,,,l2tp,info,,debug,,,critical,,,,,,,,,,,,,warning duplicate packet, droppin
On console and terminal:
I have already looked for the official forum of mikrotik but neither has no clear answer or a definitive solution.
My goal is to remove this error from my terminal and from my console log.
My current setting:
OVPN SERVER:
PPP PROFILE:
#Edit:
After contacting support, I got this error message to have no impact on the VPN. Below is the email from Mikrotik Support:
Email:
"Hello,
This error message does not have any impact on the VPN connection
establishment, it simply warns you that the client sent duplicate
message which some client software (for example Windows) do.
Best regards, Emils Z."
Thank you all for your help.
I would advise that this is probably a bug in the OVPN implementation on Mikrotik's side. Please log a support ticket with them, and provide the supout.inf file as per the usual process.
Please see this link on how to make the support info file:
https://wiki.mikrotik.com/wiki/Manual:Support_Output_File
In short, open winbox, click the make support file on the left, and then go to files and download the file to your pc. Then attach this file to the support ticket.
All,
Here is my frustrating problem that I'm out of ideas how to troubleshoot. I have a code to upload a post to a .php script. It's a standard multi-form post request done with a URLSession and dataTask(with: request) method.
I got the following error at home, then I moved to a different home and get the same problem:
error=Optional(Error Domain=NSURLErrorDomain Code=-1005 "The network connection was lost." UserInfo={NSUnderlyingError=0x60800045eff0 {Error Domain=kCFErrorDomainCFNetwork Code=-1005 "(null)" UserInfo={_kCFStreamErrorCodeKey=-4, _kCFStreamErrorDomainKey=4}}, NSErrorFailingURLStringKey=http://www.somedomain.com/upload.php, NSErrorFailingURLKey=http://www.somedomain.com/upload.php, _kCFStreamErrorDomainKey=4, _kCFStreamErrorCodeKey=-4, NSLocalizedDescription=The network connection was lost.})
However, I went out of town on business and it worked fine from the hotel. Then I tried it at another location and it worked fine there too.
SO
My old home and new home: doesn't work
Hotel two states away, and
near my office: works fine
ALSO, old home used cable modem/router combo and new home uses a different device (DSL modem/router combo), so I don't think old home and new home have anything in common.
I've got traceroutes and a wireshark capture file for connections at my new home, hotel, and near my office.
When the problem happens, there is a tcp stream that transfers lots of data, but always gets RST packets from the server before it can finish.
I realize that this appears to be a tcp/ip networking problem more than it is a Swift/Xcode problem, but I'm not sure where exactly the problem lies.
Any troubleshooting ideas?
My site sends confirmation emails from a purchase. 95% of the time, it works. The other 5% after clicking the 'Confirm' button that runs the payment and should send the email, i get the following exception:
Details:
Exception: Failure sending mail.
Inner Exception: Unable to connect to
the remote server
Inner Exception
(2): A connection attempt failed
because the connected party did not
properly respond after a period of
time, or established connection failed
because connected host has failed to
respond 72.167.234.197:25
The code to send the email is this:
Dim smtpClientPayPalSuccess As System.Net.Mail.SmtpClient = New System.Net.Mail.SmtpClient()
smtpClientPayPalSuccess.Host = "relay-hosting.secureserver.net"
smtpClientPayPalSuccess.Send(mailMessagePayPalSuccess)
FYI: I have confirmed with the hosting that I don't need any credentials, or a different port number than 25. This is also running over https.
Any idea why this would be happening only a small percentage of the time?
Thanks.
Dave
I don't know why the mail fails part of the time. As far as I know it could be scheduled maintenance of the firewalls or the mail server itself.
I would advise you to send the mail asynchronously, and not as part of the 'Confirm' button process. Just put the mail on a (persistent) store and keep trying to send it with some time in between.
Alternatively (and heartily recommended) is to send the mail from your app to a local mail server, and let that mail server forward the mail to 72.167.234.197:25. That way you get the retries for free and the chance that sending mail to localhost fails is quite small (or it should be small).
It is possible and quite likely based on your exposition, that there are actual network errors that prevent your site from connecting/communicating with the SMTP server. This could be the result of too much traffic, or maybe slow network connections. My recommendation would be to put a try/catch around the emailing code, and maybe retry sending the e-mail a few times before giving up.
When you mention that this is working 95% of the time it shows that the problem most likely lies outside of your control.
As a side note, you should maybe consider not giving up the actual IP address of your SMTP server (it is of no consequence to the question)
I have a Flex client using a Flash binary (TCP) socket for communication with a Java server. I have a localhost (Apache) server providing a crossdomain.xml file which is wide open just while I am testing.
My code successfully loads the policy file on startup.
I then connect the socket to the server without any difficulty and send a message and get a response. All good so far.
However, when I send a second message through the same socket I get a pause of about 12 seconds then a sandbox violation error:
Security Error: Error #2048: Security sandbox violation: file:///C:/apache_root/ttt1/ttt1.swf cannot load data from localhost:45455.
This is the same port and socket through which the first message succeeded.
I tried re-loading the policy file before every send, but I get the same result.
Any idea why this might be happening? I clearly have an open socket at one point. I am flushing the socket after each send and I tried doing that after each read as well, but the same result.
Thanks in advance
EDIT:
If I recreate the socket prior to every call my code works. I am struggling to believe that this is correct, but maybe there is a Socket setting I am missing.
As far as I know if you're doing binary sockets the crossdomain.xml is not loaded via http.
Have you checked your apache's access logs if the crossdomain is even queried?
You might get connection from flash via tcp from flash asking for the file on your java server (not using http. It just sends the string "" or similar). Look out for them. If you don't answer them within 3 seconds (or so) flash throws an sandbox violation.
The first thing you have to do when you want to make a socket connection is to load the policy file. This only has to be done once per load of the SWF.
Security.allowDomain(host);
Security.loadPolicyFile("xmlsocket://"+host+":"+port);
The request will be made on the assigned port(45455 in your case) your server will have to listen on that port for a request "<policy-file-request/>" without the quotes.
When that request is found then you need to return to the client the crossdomain.xml
with node <allow-access-from domain="*" to-ports="*" />
After the cross domain is sent you need to close the socket on the server side
On the client side you need to ignore the domain response as Flex will handle that however at that time you can reconnect to the socket server.
At this time you can do your data send/receive.
I have a feeling the reason it actually worked for you is because you were using the connection for the policy file to transmit your data before it timed out.
I would suggest reading up on the new style of crossdomain policies and also reading up on the protocol you are using for your socket server
I think it depends on the sandbox-policy you used in the compilation process of your swf not on your crossdomain.xml... maybe this docu helps you:Security sandboxes
But I'm not 100% sure
This sort of sounds like a cache problem. Perhaps you're pulling the first socket connection out of cache and the second one gets rejected because it's getting a 200 from the server.
You might want to add localhost to your flash security exceptions list for debugging. that will quiet the sandbox errors until you get your piece to it's production environment.
