Hello,

We use ELOG for many years and enjoy it's functions every day!

Lately, we see errors whenever we add an entry in elog: 554 MailTransferAgentServer ESMTP not accepting messages

We see this from various ELOG servers. Other (non ELOG) servers using the same MailTransferAgentServer do not heve this error.

We are able to send mail messages from the ELOG machines manually via TELNET. So, from a functional point of view, all works well.

We had this error in the past and found out that the cause of this error lies in (network) time-outs.

Questions:
1) Has anyone seen this error before?
2) Is it possible to increase the timeout value used by ELOG?
3) Are the emails that could not be sent stored in a queue/resent later or are they lost?
4) is there a fix?

Any replies are highly appreciated!

T I A !
 

Could you run elogd interactively with the "-v" flag to log the communication between elogd and the ESMTP server and send me the traffic log? 

Hello Stefan,

Thanks you for entering this thread !

Fortunately, we were able to solve the problem. A reboot of the DNS server used by the MTA (Mail Transfer Agent Server) to check the from and to address did the trick.

This server now responds within the timeout period in ELOG.

It still would be handy if you could add a parameter to the config file that allows us to fiddle with the timeout value. The DNS server used by the MTA has to deal with heavy load.

Best regards,
Ron

After installing ELOG on a new Windows 8 machine, I found everything working fine... until I went to make a new entry.   New entries work... but the FCKEditor toolbars do not show up.  I tried a variety of things (start as a service, start not as a service, run as administrator), but nothing made the toolbar appear that I coumd find.  The ELCode editor toolbar appears, but the nifty FCKEditor toobar never appears.  I could not figure out how to debug FCKEditor.  Any ideas?

Thanks for reporting that problem. Indeed the elog292-1.exe distribution has a bug in the directory structure. I fixed that in elog292-2.exe, which you can download from here:

Thank you.. that version works fine for me.

  67462   Fri Mar 1 16:35:21 2013 Warning Mark Bergmanmark.bergman@uphs.upenn.eduBug reportLinux2.9.2elogd crashes with malloc() memory corruption

 I'm having an issue with ELog 2.9.2 revision 2455 where it crashes consistently with:

*** glibc detected *** /usr/local/sbin/elogd: malloc(): memory corruption: 0x0000000014977210 ***

(the address varies). The crash seems to be triggered by the attempt to email a log entry. The log entry itself is saved. If I open the existing message for editing, make no changes, then Submit the message (in order to send email), the daemon crashes.
 
The behavior is consistent on multiple servers, each running CentOS5.9.

  67469   Fri Mar 22 19:41:31 2013 Warning Konstantin Olchanskiolchansk@triumf.caBug reportLinux2.9.2Incomplete SSL proxy instructions, insecure result.
The instructions for securing elogd using an SSL proxy are incomplete.
http://midas.psi.ch/elog/adminguide.html#secure
http://midas.psi.ch/elogs/contributions/11

If you follow these instructions, elogd will still listen for and accept non-SSL connections on it's own TCP port bypassing the SSL proxy.

(True, the elogd TCP port number is somewhat secret, so there is some security-by-obscurity here).

To secure the elogd TCP port against connections that bypass the SSL proxy, elogd has to be started
with the "-n localhost" command line options.

To add this option, one has to edit /etc/init.d/elogd. I do not know if this change will be lost when the elog rpm package is updated.

It would be better if this option could have been specified through elogd.conf.

The "-n" command line option is not documented here
http://midas.psi.ch/elog/adminguide.html#config
but is visible if you run "elogd -h".

P.S. Even with "-n localhost", users of the local machine can bypass the SSL proxy.

K.O.

I added the option "interface" to the config file. So you could do

[global]
...
interface = localhost


It was not there originally since most people who care about security use a firewall. The firewall (either locally or one another machine), opens only port 443 for the secure connection and 
not the non-secure one (typically 80 or 8080). This way this has not been an issue in the past. As you guessed correctly the -n option would be overwritten by an rpm package update, so 
that's why I added the "interface" option.
  67474   Thu Apr 4 17:47:12 2013 Question Daniel Camporadcampora@cern.chBug reportLinux2.9.2Checking logging before posting

Hi there,

 

Here's a bit of a special scenario. There's no server-side check the user is logged in upon posting, but it rather seems the server relies on the post data sent from the form.

An example of this can be triggered on a write restricted elog, by hitting on New and logging out in another tab. Then posting, from the first tab, will post as if the user was logged on. Hitting back and posting again also works.

 

Cheers
