I made copies of both servers' files and ran two elogd servers on my Mac on different ports, compiled from a fresh checkout of 2.8.0, and the same behavior was observed as I repeatedly made test entries and synchronized. This suggests it isn't specific to Linux architecture, 64-bit or otherwise.

We plan to use ELOG with mirror servers in a larger scale here, so I'm interested to know more about your problem.
Could you boil down your configuration to a minimum that still allows a reproduction of the problem and post those configurations as attachments?
Then I would try to reproduce it here. Best case I'll find a bug fix, worst case I'll reconsider the use of mirror servers ;-) |

I have been using the mirror mechanism for one year for the online T2K /ND280 (neutrino oscillation experiment at J-PARC, Japan). It has been a savior to allow access to all collaborators to the Elog. The experiment online computers are all behind a double firewall that allow only communication through ssh and http in one direction: from the inside to the outside. The master Elog is located in Canada and accessible remotely to all collaborators. The mirror Elog is located inside the firewall on one of the online machines in Japan and synchronization is setup to run automatically every 5 minutes. There are 10 logbooks defined for each of the sub-detector groups.
At first I encountered a big problem when messages were added on both sides. It turned out that Elog mirroring does not work when the two instances are running on different time zones. After I set the machine in Canada to run on Japan time (JST), no further problems have happened. Postings are routinely entered on either of the Elogs and synchronization works well. This feature is essential to having a workable Elog for the T2K experiment.
I had reported the problem of timezones to Stefan last year. He was going to put it on his wish list.

Thank you Andreas!
So I will generate the preset entry in a shell script.
And now to something completely different:
Is there a way to make the elogd options -x and -install work together?

I just got a Proxy error from your site: When I clicked on the change password link that was sent to my email, I entered my new password (which was the same that I believed to have used before) and after submitting this form, I got the Proxy error. Also I find that I can never login with my once set password. Is it the Email or username on gives in the login field? Other quirk: I never can preview my post. When I click preview, nothing happens. Submitting worked today but yesterday I was unable to submit a post. I clicked several times on the submit button and nothing happened. -- Christoph |

It seems that the submit/preview problem is solved. Submit/Preview buttons at the bottom of the page seem to work on the attachments only.
Sorry for the oversight on my side.

Let me add one observation though: I always have to put the Submit or Preview button twice in this forum. The first time no reaction happens. The secend click dows the action.

Yes this observation is right. It's related to a new "fix" I was asked for: People do not want an entry to be submitted if they fill in an attribute and hit <ENTER>. So I added some javascript to prevent this, but the bad side effect right now is that you have to click Preview or Submit twice. I'm working on it. |

Hello,
I'm new to elog. I've installed it under Slackware 11. Everything worked smoothly until I wanted to establish access control. I followed the steps described under Access control heading in Syntax of elog.cfg chapter. I specified a new password file name and the following steps with no problem. After having created a new user I stopped elogd and added Admin user to config file. And here is my problem - each time I want to login to elog, I get "Invalid user name or password!" message. The meaning of it is obvious. So I have repeated all the steps several times. Of course I paid attention to enter user name and password correctly but I can't get rid of this message. For sure I making something wrong, but what it is ?

Can you try the current SVN version?
http://savannah.psi.ch/websvn/filedetails.php?repname=elog&path=/trunk/src/elogd.c&rev=0&sc=0
There has been some issues with the password encoding, maybe this is fixed now.

Thank you Stefan, it works now
Best regards
