  69104   Fri Jan 31 18:22:50 2020 Question Duarte Alexandre Vicente Paisduarte.pais@psi.chQuestionWindowselog-latestRunning ELOG as daemon in Windows not working

Hi, I tried to set up an ELOG from a windows machine. Its functionalities work without any problem, but I cannot access at all this ELOG from any other machine. I tried to search in this forum, but with no avail.

Could someone perhaps tell me know how to fix this problem? Or did I miss something obvious in the configuration of the ELOG?

Cheers,

Duarte

Probably a problem with your Windows Firewall. You have to convice your OS to let you in.

Do you know which settings in the firewall panel I should change (windows 10 machine)? I went over all the access rules and could not find anything corresponding to the ELOG.

I'm not a Windows user so I don't know details. But I believe you have to make an exception in the firwall for the elogd.exe executable. You can certainly Google how to do that for any executable.

A statement like "core dumped" does not help much. Same with valgrind memory leaks. I need a full strack trace with all parameters when the segment violation occurs. The easiest is when you run elogd vom inside gdb, and once you get the signal, do a "where" to see th full stack trace.

As you can see from this forum, there is absolutely no crash when you upload any file, so it must have to do with your config file or anything whcih is special in yoru environment. We have to find what this is so that I can reproduce it here.
