I updated the EL9 rpms, so please try again.

Great, thank you again. I have now installed the latest and the problem appears to be gone.

I changed elog to interprete the content-length header case in-sensitive and committed the change. Can you try again?

I'm trying to run elog behind haproxy, but get the error "Invalid Content-Length in header" on posting.

As stated in the manual, haproxy rewrites all headers to lower case.

elogd parses the content-length header case sensitive which is against the HTTP RFC. This might also apply to other headers that get parsed.

For now I'm using the workaround from the manual:

global
  h1-case-adjust content-length Content-Length
  h1-case-adjust content-type Content-Type

backend elog
  option h1-case-adjust-bogus-server
  server elog 127.0.0.1:8080

But as the manual states, this should not be  used as a permanent solution.

I put the ELOG service behind an Apache reverse proxy which is now sitting behind the HAProxy. It works like this, but it's just a workaround. I am pretty sure that ELOG has problems to communicate with HAProxy correctly and it seems that Apache is more forgiving. So that the chain HAProxy -> Apache -> ELOG and vice versa is working.

If anyone manages to figure out what's wrong, I am happy to get rid of the extra reverse proxy layer!

I am still struggling to get ELOG running behind a load balancer and hope to get some advice here. As already reported in https://elog.psi.ch/elogs/Forum/69542 I observed an infinite loop of redirects when prompted to log in and using a non-empty password file. Without a password, the service worked as expected. This was with version 3.1.3.

With the new version 3.1.4-3, I get another error: "Invalid Content-Length in header" when I click on "submit" of a new post. Viewing the logbooks works fine. The instance is currently live and running here: https://elog.test.km3net.de but I might change it anytime due to debugging etc.

This is a kind of difficult thing to debug (I spent the whole day and no progress). The only thing I've found was this post: https://techcommunity.microsoft.com/t5/iis-support-blog/invalid-content-length/ba-p/3038724 where it seems that some responses are not RFC conform and were rejected in the load-balancer.

The load balancer I use is HAProxy, the same as in my old setup where I got the infinite redirects, and I can't find any setting which would work. To my understanding, the most basic setup should work just fine. The SSL termination is on the load-balancer side so ELOG doesn't even have to know anything about it. The configuration is below. I am running a single instance, so there is not even replication with session keep-alive via cookies or anything fancy.

I also want to mention that I am runnin around 30 different services behind the load balancer and none of them are having any issues with the SSL termination or the load-balancing itself, that's why assume that something in ELOG is either non-conform or buggy.

Any thoughts? I'd really like to use the same infrastructure for the ELOG service as for every other service (automatic certificate renewal via letsencrypt, load-balancing, easy movement to other nodes, SSL termination etc.), to minimise the complexity of our Docker Swarm system.

Btw. I am running ELOG with -v but I don't see any error whatsoever in the logs:

Hi!

I am not sure if this is a know issue: it seems that the equation editor does not work anymore. Is there any fix or alternative method to type latex formula in the log? 

Thank you!

  69831   Tue Sep 24 19:38:23 2024 Entry Gabriel Lopezgabelopez@bnl.govBug reportLinuxelog-3.1.4-3Catgegory filtering

Currently have multiple logbooks hosted with elogd. One book is having an issue with Categories. The user regulary uses the category filtering to see one subject for the whole month. This past week it hasn't been working properly. When choosing a drop down category to filter there are not logs found. I've notice the fields under the categories change randomly. Sometimes it would add a % sign where there should be --. Some other fields go from displaying -- Subject -- to just the dashes, thats when the filtered eLogs do not show. Clearing out the erroneous characters can eventually load the specified logs. Has anyone else seen this? Should I just upgrade the system and hope for the best?

 

PS. while writing this I was able to mitigate the issue by removing the troubled fields from the quick filter section. I'm pretty sure this will not be an issue for my end user but any input is appreciated.
