My problem is that I don't even reach the page where I can enter a password. If you go to https://elog.test.km3net.de and click on a logbook, you'll see that it immediately goes into a redirect loop. I already logged the routing but there is nothing else...

Yeah, after you enter a password, elog redirects to what it finds in "URL". You can trace that by opening "development tools" in Google Chrome, go to "network" and watch packets going back and forth. I never worked with the load balancer, but maybe you need a different "URL" containing a '/' at the end?

I also tried the default configuration (example config) and it that works behind the load balancer. So I guess it's related to the password-page, which causes this redirect loop? Our logbooks are all password protected, so when a logbook URL is clicked, it should first present the login-form, and that's where it chokes.

Thanks for the quick reply! Sorry, I forgot to paste the "global" part of the config, I have that URL already set:

[global]
;Main Settings
;=============
Usr = elog
Grp = elog
port = 8080
SSL = 0
URL = https://elog.test.km3net.de
Title image = <img border=0 src="KM3NeT_logo.png" alt="KM3NeT logo" height="35px">
;SMTP host = smtp.fau.de
Display mode = summary
Thumbnail size = 500>
List Menu text = clock.html
Menu text = clock.html

Probably you need a setting

URL = https://elog.test.km3net.de

or so in your elogd.cfg file.

We were running ELOG for many many years in our experiments and the instance was operated on a Debian XEN server as a container. I am now trying to migrate it into our Docker Swarm cluster and I am using the https://hub.docker.com/r/de1lz/elog-docker Docker image, which works very well with our logbooks when I run it as a single container. However, when I put the container behind my load balancer (HAProxy) using the simple HTTP mode (which works very well for all the other HTTP-based services) with this simple configuration:

backend be_elog.km3net.de
    mode http
    server-template km3net-elog- 1 km3net-elog_elog:8080 check resolvers docker init-addr libc,none

I get a "too many redirects" error when I try to access one of the logbooks. The starting page works fine, but every other link leads to a pile-up of redirects.

Here is the current instance running, where you can see the behaviour: https://elog.test.km3net.de (all log entries deleted and only two logbooks activated)

My question is: what kind of redirect could go wrong here? I don't know how the internal HTTP server of ELOG works, but maybe someone faced similar issues.

My ELOG configuration is also pretty basic, and as I wrote above, everything works when I run it without the load balancer (single instance at the moment). Here is the top part of the configuration, it contains a few dozens of logbooks but they are configured the very same way.

Hi, I have an issue with my local elog setup. it's usable but one function is just not working.

Problem

I'm getting weird error messages when trying to write or read entries from the CLI client.

I have googled a lot and most elog client examples are not giving the actual output, more like elog -h <host> -p <myport> -a ... -x -m "myfile" but I hope I got the options right.

Upgrading did not change the behaviour.

Question?

• anyone see problems in the commands I tried below
• with OSX in general
• have a recent setup on OSX that just works

Env

I'm running elog on my OSX laptop for tracking issues / improvements on client's IT systems. It's proven really good for storing my notes.

One "kink" is I kinda need both of them on the laptop since I cannot assume to have working network connectivity, i.e. when documenting network outages or datacenter maintenance where everything is off.

One thing I couldn't get to work was the CLI. Today I upgraded to the latest build, and tried again.

Env: OSX 12.4 (x86_64)

elog Client compiled from latest source tree (bcd7b50edd3d687425e6c5b0906dc02c8690a24e)

with minimal adjustments (turn off SSL since I can't get it right on OSX, rename two .c files in mxml to .cxx)

Outputs

$ echo "blah" | ./elog -h 127.0.0.1 -p 8080 -l intern -r 2 -x
Cannot retrieve host name: Undefined error: 0
$ echo "blah" | ./elog -h 127.0.0.1 -p 8080 -l intern -r 2 -x

As per the messages, I'm not entirely sure if it's an issue with the client or the server. upgrading both components made no difference.
