What I want to do is measure broadband speed using c#.
To do this, I use NetworkInterface.BytesReceived and BytesSent to get the current amount of bytes sent and received from my network adapter and get the DateTime.
Then I download/upload a file and get the BytesReceived/BytesSent and DateTime again. The download/upload speed is just the the difference between the BytesReceived/BytesSent divided by the time difference.
Now I am wondering if there is a public FTP server where I can download and upload files.
Tele2 provides ftp://speedtest.tele2.net , you can log in as anonymous and upload anything to test your upload speed. For download testing they provide fixed size files, you can choose which fits best to your test.
You can connect with username of anonymous and any password (e.g. anonymous ). You can upload files to upload folder. You can't create new folder here. Your file is deleted immediately after successful upload.
Found here: http://speedtest.tele2.net/
Try ftp://test.rebex.net/
It is read-only used for testing Rebex components to list directory and download. Allows also to test FTP/SSL and IMAP.
Username is "demo", password is "password"
See https://test.rebex.net/ for more information.
Currently, the link dlptest is working fine.
There's lots of FTP sites you can get into with the 'anonymous' account and download, but a 'public' site that allows anonymous uploads would be utterly swamped with pr0n and warez in short order.
It's easy enough to set up your own FTP server for testing uploads. There's plenty of them for most any desktop OS. There's one built into IIS, for instance.
NO LONGER VALID. Don't use it.
You use http://test.talia.net/
FTP Test You may also test download and upload rates by anonymous FTP. Use the following settings:
Server: test.talia.net
Username: anonymous
Password: <your email address>
To test upload, first cd to the "incoming" directory. Files uploaded here are periodically removed, and cannot be downloaded again.
I have found an FTP server and its working. I was successfully able to upload a file to this FTP server and then see file created by hitting same url. Visit here and read properly before use. Good luck...!
There are both HTTP and FTP servers for upload and download.
HTTP server for upload:
FTP server for upload:
I'll keep on adding more.
