Hi,
that Sebastian would be me. I replied to the first entry, as it was a draft (site reloaded incorretly...) and now I can't see the post anywhere. But this is off topic.

We have elog running on port 8000 and forward the traffic via Apache to it. Apache handles the SSL and other sites on the server.
All you need is a apache site configuration like the following. The parameter you want is CustomLog. (Have a look in the internet for options.)
I have also used nginx as webserver and know it can also handle this proxy setup.
If you use the following config, the elog config needs the URL attribute in the (global) config.

Best wishes,
Sebastian

Hi again everyone; a Sebastian suggested I use a reverse proxy to complete my need to have logs show up when someone 'lands' on my first entry page. I see that Elog will only start recording logs when someone has actually started to do some work.. like login, read a post, etc... but NOT when they first enter the login page or 'listings' pages. I have tried fowarding from my router (both lighty and Apache) but so for no good. I will also look into  a vhost option and shareing the same port (very difficult- if even possible)  to  solve my dilema.

Hi, I have been trying for a long time to get my web server logs to record when someone accesses my Elog server. I've tried Apache2, Lighttpd, and others, all with no luck. Either the web servers complain that the port I have Elog on is in use, or I just don't get any readings. I need to see who is accessing my  Elog from the web, and I hope there is a way.

Thanks again for such a wonderful program,

Thank you soo much Sebastian once again for helping me!! This is something that will help me very much in the future with other situations similiar!

Obviously there is: this logbook does add line breaks?!?

Maybe it is only a problem with entries made by the "elog" command?
I'll find it out and re-post.

Okay, I found two ways to add very long lines:
- if the very long line does not contain a space then this will screw the printout.
- if the line has been added as plain text using the elog command, there will be no line breaks added.

It would be nice if the elog command would have an option to break lines to a maximum line length.
But for the moment I'll just modify the applications that make use of the elog command.

Yepp, this is a (missing) feature of the elog command. Can you pre-process your messages outside of it, or do I have to add code to elog to do that?

Well I answered part of my own question already.. I can have a start page different from what is default, and I can edit the orginal one by simply copying it and modifiying it to my hearts desire. I still have isues  after making menu selections from that page tho,  when the program (server) takes me to a site called  for example: ../forum/index.html?cmd=Config. I cannot find out how to prevent or modify this behaviour. I am supposing tho, that because I am using my own original index.html (start page), that the program is not modifying it (on the fly), like it does with the oringal web pages?  I am also still currious if the program does indeed create/modify pages on the fly, and if it does, where does it store them on my hard drive (or is it only put in memory temporaly?). Thanx again :)

Hi and thanx for such a wonderful program! I was wondering how I might edit, change or add to the landing pages. In other words the first pages that show up (or any for that matter) when you login to a book. I can view the code ok in my browser using that function, but when I search for the actual page and it's locale, I cannot find it. Is it created on the fly by the server? If so, how can I change them.. as I want to add for instance javascripts to manipulate the pages and data more, without actually loosing the main essence of the program (log books). Thanx

Per default, all pages are created dynamically by elogd directly from its C code. So nothing to change easily except hacking the code. There is one exception which is the start page you found already. To change any other page, you have to modify the C code. There is one more (dirty) trick: You can sneak in JavaScript code on every page via the "bottom text" option. This code can then modify the DOM tree and changes pages, but you need to program this in JavaScript.
