Printer error: Connection closed by remote host #278

According to the error log and from other sources, this is the error that the PhD's in the physics department are receiving.

Can confirm. Got this error message several times earlier today as I was printing some files. Worked after a couple of tries though.

Isn't this just chalmers blocking too many unsuccessful password attempts?

Kalior commented 7 years ago

Could have been, but it did not seem that way. In abbreviation I went through the following steps:

  1. Write wrong password (Got wrong password error message)
  2. Got this error message
  3. Successfully printed file
  4. Got this error message again two times
  5. Successfully printed file

So I guess it could still be the case if I was blocked on one of Chalmers' hosts but not the other?

Kalior commented 7 years ago

In any case, the error message could be clearer

I may be wrong, but I think the printer script will randomly try one of the two servers available. Thus the server IP may have been banned on one server, and not the other.

But I agree with @Kalior that the error message may be improved. Also, we should probably implement "banning" after x tries to avoid DOSing ourselves...
