Hi Siddharth, I just found the problem. Go to the Coordinator and attach your user AS to another point other than ISD18 (WISC). There is a problem with that attachment point for some time now, so don't use it. Thanks and regards, Juan A.

Hi Siddharth, We don't have any experience with OpenVPN for Windows. I would suggest these two steps to troubleshoot your setup: - Check with a VM that your user AS runs correctly. Since we have lots of experience in Ubuntu 16.04, install first a VM like that, or eve better, install the Vagrant-Virtual Box VM that you see being installed in the `run.sh` script in your configuration from the Coordinator. - If the previous step worked, check only the VPN connection. As you were saying, it will probably fail. Tell us and we will investigate further. Thanks and best regards, Juan A.

Hi Siddharth, It seems to me that `network-test` is to blame. Try running it in other machines and it will always complain, if my hypothesis is correct. Also if you open it you will see these lines: ``` [ -z "$CHECK_WEB_URL" ] && CHECK_WEB_URL="http://network-test.debian.org/moo " [ -z "$CHECK_WEB_MD5" ] && CHECK_WEB_MD5="5cd5515e6d2f9026fef667cdef4cda42" ``` If you follow the usage of them you'll see there is a call to curl and a md5sum on the content. But that URL returns a 404, so I would not trust the test itself. Best regards, Juan A.

Hi Siddharth, There is no attachment: http://lists.inf.ethz.ch/pipermail/scion/2019-August/thread.html#4 Also, I don't understand when you say there is a change in a file when connecting to SCIONLab. Maybe if I can see the file it would be more clear (what was the file?). What is it changed and when exactly ? And what do you mean by "The md5 hash value of *some* file was changed when received." ? when received from where? Thanks and best regards, Juan A.

Change in md5 values
by Siddharth Mehrotra 13 Aug '19

Hi all, I noticed an interesting error while connecting to SCION. As soon as I typed vagrant ssh to connect to SCION network, I noticed system reporting modified files. The md5 hash value of *some* file was changed when received. I am not sure whether this has anything to do related with SCION or my internet issue ? Suggestions? Best Regards, Siddharth Siddharth Mehrotra Working Student Usable Security & Privacy Group, Informatik 4 Rheinische Friedrich-Wilhelms-Universität Bonn Bonn, Germany.

Re: [Scion] Beacon server log generation problem with SCIONLab VM
by Frei Matthias 08 Aug '19

08 Aug '19

Dear Merlec, the screenshot seems to indicate that none of the SCION services was able to start, and the log of the beacon server hints at an invalid topology file. My guess is that your configuration folder contains configuration files for an old, incompatible SCION version (*). If this is the case, the simplest way to fix this would be to go to the scionlab.org website, download a fresh copy of the configuration for your SCIONLab AS and re-initialize the VM (again, sorry). Best Regards, Matthias (*) My guess is that your AS had previously been working because it received newer configuration through automatic updates. It's possible that this automatic update process does not work as expected when recreating the SCIONLab VM starting from an old configuration. ________________________________ From: mlecjm mlec <mlecjm(a)gmail.com> Sent: Monday, 5 August 2019 1:30 PM To: scion(a)lists.inf.ethz.ch Subject: Beacon server log generation problem with SCIONLab VM Hello SCIONLab Team, I am facing some problems with my SCIONLab VM ( 17-ffaa_1_228), which is not able to generate the beacons server log. The following is the error message shown after running "checkbeacons" or "tail -f $SC/logs/bs*.DEBUG" command. [image.png] Could you held me to figure out what is the problem and how to fix this it ? Basically, the VM was working well until I updated VirtualBox form 5.2.28 to 6.0.10 version, which asked me to update also vagrant from 2.1.1 to 2.2.25 Version, and after that the SSH PublicKey authentication and password failed, I could not access again to the SCIONLab VM. So I decided to destroy and reinitialize the VM, that why I am facing this situation. Sincerely, ----- Merlec Mpyana M. Ph.D Candidate, Embedded Software Engineering Lab.
