Re: [MooseFS-Users] main master server module: packet too long

[Jacob D. <jac...@ci...>]

Hi Agata,

thanks a lot for the clarification and nice insight!
Seems to be something that happens on boot only. Restarting the service afterwards gives me no such message.

Hi,

I decoded the bytes sent to your master module and they look just like this:

GET /met

So, this is definitely not MooseFS protocol. It looks like good old
HTTP. And the connections are coming from localhost (127.0.0.1). Do you
have a local process that scans open ports?

Anyway, master (and other MooseFS modules) will just ignore any
communication that is not in MooseFS protocol and close the connection.
So it will not stop the system from working, however, you will be
notified in logs each time this happens.

Regards,
Agata
