Oops, there was a bug. I added the resource directory in front of the logfile name, 
which is not correct if the logfile name contains an absolute path. I fixed that in 
the current CVS version. As a temporary fix, remove the resource dir in your elogd.cfg 
or remove the full path in the logfile (the file will the be put into the resource dir 
of course...).

I have had this installed for about two weeks now and it seems to be working
fine. I haven't seen any problems at all and none of the other users have
reported any.

Thanks.  This is very helpful.

That's really weired. The file is displayed at the bottom of single messages, 
and the message list, but NOT at the form, which you reach with the "Edit" 
command. So all I can suggest ist the following:

- Hit the reload button on your browser each time you change that file, to 
make sure the browser does not display a page from its cache

- The HTML file is *included* in the normal page, so it should not contain 
<HTML> or <BODY> tags. Start with a simple file containing something like

<center>Test</center>

and see what you get.

- Make sure the file is in the elog "resource" directory, which gets 
displayed if you start elogd with the "-v" flag.

Let me know if any of this helped.

Due to frequent requests, the elog utility reads the message body text from the 
console (stdin), if it's missing on the command line (like in your case). Under 
Linux, you can then pipe some text into elog

cat message.txt | elog -h ...

or under Windows

type message.txt | elog -h ...

If you enter the text directly, you have to finish it with Ctrl-Z / Return
(Windows) or Ctrl-D (Linux). If you do not want any text, you can write

elog -h .... -a Status=operational " "

to submit an empty text (well, almost empty, contains single blank).
  414   Sat Jul 26 10:29:33 2003 Reply Stefan Rittstefan.ritt@psi.chQuestion 2.3.9Re: Need fault-tolerance recommendations for using ELOG for Server Logs
I was thinking since some time already about mirroring between elog servers, 
and actually started already some implementation.

The problem with mirroring on the file level does not work. Assume two 
servers "serv1" and "serv2". Then assume that one message gets submitted on 
serv1 and at the same day another message gets submitted on serv2. Now you 
have on both servers a file 030726a.log, but you cannot copy this file 
simply from one server to the other, since you would overwrite the message 
submitted on the other server. Furthermore, you need file level access, 
which is maybe easy between your laptop and your desktop computer, but not 
if the two mirror servers are in different countries. Like in our 
collaboration we have three servers located in Switzerland, Italy and Japan 
(meg.psi.ch, meg.pi.infn.it, meg.icepp.s.u-tokyo.ac.jp), where we cannot 
have direct disk access.

So what I propose is the following mirror scheme:

o Each elog server may contain a list of mirror servers in the configuration 
file

o Each elog server calculates an MD5 checksum from all local messages

o Synchronization between servers can be triggered manually (by clicking 
on "Synchronize") or automatically at a given time and interval

o On Synchronization, the elogd server fetches the MD5 list from the mirror 
server and compares it with the local list

o If a message has been edited remotely but not locally, it's fetched and 
stored locally, same in the other direction

o If a message got edited on both sides since the last synchronization, the 
user is asked to resolve the conflict (keep local or keep remote message)

o If there is a new message locally, its submitted at the remote server, but 
with the same submission date/time as locally, same in the other direction

o If new messages are present on both sides, their message ID is changed so 
that it is unique, then they are copied over. If there are already replies 
to this message, their link (using the message ID) is changed accordingly

So I plan to implement this scheme in the next time. The MD5 checksum is 
already there. If anybody has comments or additional wishes concerning 
mirroring, telling them right now would be great, since I then can 
accomodate them easier during the implementation.

No, it cannot be done right now, but it's on the wishlist since some time. 
So I added your vote there.

Ok, added to the wishlist.

I had that request more than once. The problem with it is that I cannot 
implement it, since he have no LDAP server here at our institute to try it. So 
if someone teaches me how to do LDAP authorization correctly, I can put it in, 
but not before.

I'm German as well, but cannot understand your question. Can you write an 
email in German directly to me?

Ich kann Deine Frage leider nicht verstehen. Kannst Du sie mir direkt in 
Deutsch per Email schicken?
