Incorrect implementation of TFTP? #63

Closed t-oster closed 4 years ago

t-oster commented 4 years ago

Hi, some of our users have a problem which boils down to LAOS TFTP server not correctly working with apache commons-net TFTP client. See here: https://github.com/t-oster/LibLaserCut/issues/131 It seems as if the LAOS tftp will answer from port 69, which should not be the case according to https://issues.apache.org/jira/browse/NET-414 (an incorrectly written TFTP server replies to a request from a control socket instead of building a new socket that attaches to an ephemeral port).

Maybe there is an easy fix for the LAOS firmware? Otherwise we will have to patch commons-net for VisiCut to work, I don't think they will revert their check.

Should be fixed in latest release. Tested against Visicut 1.9.41-ge370801a Try this firmware: laoslaser-2020-03-23-a459d9.bin

Thanks @pbrier, nice to hear you're still in business.

pbrier commented 4 years ago

Making my laser covid19 ready. I would not recommend to upgrade your firmware in a crises, but if you need: now it should work with the latest Visicut again.@t-oster: Did you test it?

t-oster commented 4 years ago

@pbrier no, but I trust in you ;). My lasercutter is not very busy atm.

(It might be a good idea to create a Release, that way people can easily get notified (after watching "Releases only")

It's great to see you both are still keeping things up to date :) I understood Fablab Amersfoort had to use an old version of Visicut because of this issue.

Should work - our change at makerspaceleiden.nl was virtually the same - except we also block a new incoming during the send port being active.

Thank u so much !! Never upgraded the firmware after first installing it :-| After the update it did not start up (stuck at start screen) I fixed it by upgrading the mbed LPC1768 firmware from 16457 to 141212

Hi @PieterBosNr1 I am facing the same problem, can you please tell me, how you updated the MBED Firmware? Isnt it compiled into the LAOS firmware?

Thanks!

PieterBosNr1 commented 2 years ago

Hi @MartiniMoe as far i can tel it is not (but i clould be wrong), so what i did was: connent de mbed. drag de firmware file to the mounted drive. disconnect en and connected de usb cable. after a short time de firmware should updated.

But is was stil having problems with it (not connecting at al)

Went ahead a bought a new brain for the laser i wanted the cohesion board but that was not avalable at the time (https://cohesion3d.com/) So i got the awesome tech mini gerbil mg3-mini-gerbil. This one also works with lightburn (which is worth every penny).

Hope this helps
