Append with offset > 9 does not work
Hi,
I have the following problem:
When using append and the file i try to append to is not bigger than a size of 9 bytes, everything works fine. I can append 1, 3, 20 or even 200 bytes.
But when the file is bigger than 9, i can not even append 1 single byte.
This log shows that i started with a size of 3 and append 3 more bytes every time. It works 3 times but as soon the offset is 12, nothing happens. (I cancled the connection after 10 seconds because I know I would get a timeout, that's why it says "kicked").

Any ideas on that?

Any ideas on that?

Re: Append with offset > 9 does not work
There's nothing special about 9 or any other offset.
A Wireshark dump of the network traffic would be interesting to see here.

Re: Append with offset > 9 does not work
Hi, thanks for your reply.
Sure i can do that. I recorded the failed append attemp, but my record has like 1500 entries.
You want me to apply any filters? Or maybe just a specific range of entries? Because i don't really want to post the whole record.
Maybe you can tell me what i should look for?

Re: Append with offset > 9 does not work
Everything on the control connection from the PASV command to the 421 reply. Also everything that is happening on the data connection, check the PASV reply to see which port it uses.
Re: Append with offset > 9 does not work
Hi botg,
as you suggested, i checked the data connection and compared the < 9 offset and >9 offset connection. (see attachments)
For some reasons, the FTP-data are not sent with offset > 9. You need any of these messeges more detailed?

Re: Append with offset > 9 does not work
What's with the duplicate/out-of-order packets?
Are you using any third-party software firewall?

Re: Append with offset > 9 does not work
Hi botg,
i have no idea where these packets come from.
But i can show you a detailed view of these packets.
Well i am not quite sure, i can descripe my setup.
I am sending the FTP commands from a SPS via a network adapter to my laptop. The laptop uses a virtual machine where the FileZilla Server is running. The VM has no firewall or anti virus installed, even windows firewall is disabled and all relevant ports are opened. In my host machine there are some firewalls, but the network adapter is directly briged to the VM, so i don't think these host machine firewalls should block anything?
So here is for example the out-of-order packet.

Re: Append with offset > 9 does not work
According to the dump the client simply hasn't sent any data on the data connection.
It's highly likely that it's a client-side problem. PLCs aren't known for having great networking capabilities, quite the opposite actually.I am sending the FTP commands from a SPS
If it is merely bridged then any host firewalls could still interfere with it. One way around that would be virtualizing the physical network adapter through I/O MMU virtualization, usually available through Intel VT-d or AMD-Vi. I have no idea how to configure any of that though,The laptop uses a virtual machine where the FileZilla Server is running.

Re: Append with offset > 9 does not work
Yea thats what i thought too, thats really strange.
Ok so you think with my Filezilla Server everything is fine right?
Then i have to check if there is really any firewall in my host machine that blocks the communication.
Anyway thank you a lot for your time. Even if we could not solve the problem, you helped me a lot.
Have a great day.

Re: Append with offset > 9 does not work
Yes, log and dump show nothing wrong with FileZilla Server.Ok so you think with my Filezilla Server everything is fine right?
