Strange Names in Stack Traces

Question

Hi,

Exceptions from REBEX SFTP FileServer connected with Expandrive

I have many exceptions with strange stack traces.
What is "zoqqa.tvtif.gvkkf"?
What is an invalid packet?
How can I handle an invalid paket gracefully?
How can i avoid invalid pakets?

Stack Trace e.g.
2021-07-06 15:27:53.175 ERROR FileServer(1)[2129] Server: Session 728: Error: Rebex.Net.SshException: Received invalid packet.
at zoqqa.sddkl.qsfvu(Byte[] p0, Int32 p1, Int32 p2)
at zoqqa.tvtif.gvkkf()
at zoqqa.tvtif.bglrx(Int32 p0, Int32 p1, Int32 p2, Int32 p3, SocketException p4)

Thanks
Kai

Hi,
'Received invalid packet' exception is a very low-level exception that is thrown when the, well, invalid (has bad/unexpected shape) packet is received from the remote party. It is not expected that you would be able to handle/prevent this kind of exception.

To be able to tell more about what is going on and why the SSH packet is invalid, please create the communication log on the Debug level and send it to us (support@rebex.net) for analysis.

'Strange' names in the stack trace come from the obfuscator - unfortunately, our code must be obfuscated to prevent stealing our intellectual property.
