Thanks to you, Stefan !

You software is very usefull for us and it's nice to have support.

Have a nice day !

Thanks for the detailed investiations and report. Finally I could reproduce the problem by having messages with a text body size close to 250000 bytes (some internal limit). Never thought that someone really has the patience to write 250'000 chars in a single message, but I guess you did some copy/paste from a large file. Thought in such cases people use attachments. Nevertheless, I fixed an internal memory allocation problem, now it shoudl be fine to have such large messages. Change is committed.

Stefan,

I cut the log in two parts w/o modifying the content and the search runs. It seems that the size of this entrie 426 is closed to a limit (as during testing, i met a message after clicking save to recompile elog to increase a size of something), so it could be the problem.

I reduced the entrie size by extracting the last part in a new entrie and it seems to be OK.

The old size was 250099 bytes. New size is 240084.

I hope this will be OK.

Regards

Hi,

You rights, CFLAGS should not be in specfile to take care of distrib env.

Btw, I sent in the past an update for build process of Stefan delivery to generate src.rpm file copatible to tarball version. I think Stefan did not have time yet to test and to check.

With the enclosed SPEC file, you can build ELOG with options at rpmbulld command w/o modifying sources. For exemple,

rpm -i elog-.....src.rpm

rpmbuild -bb --with ssl --with pam --with ldap --with krb5 ~/rpmbuild/SPECS/elog.spec

 

I enclosed also the SRPMS i used for my projects. Be careful, It's maybe not uptodate of last GIT version or PSI releases... but you can test it on your RPM distrib. It should be nice to hare your feedback.

Bye,

Laurent

Hi, 

in commit 1812e7c, specifying CFLAGS to make command in elog.spec, renders all other settings in Makefile void. That is, if I want to include any of KRB5, LDAP, PAM support, and change makefile accordingly, then when producing rpm they are not taken into account. Anyway, CFLAGS in Makefile are already set to the same defaults, so why it is redefined in spec file?

Hi,

It seems that ELOG does not support LDAPS but only simple LDAP connection.

Hi Sebastian,

 

Nice to hear !

So i retried some tests and in fact, as my NAS LDAP is using self-signed certificate, connexion is refused by openldap libs from ELOG (ldap_simple_bind_s Can't contact LDAP server).

By disabling certificates verification in ldap.cfg on ELOG VM, i could connect using LDAPS URL...

Maybe it should be an option to add in elog.conf... :-)

 

 

Thanks for information,

Laurent

Hi,

Maybe it could be useful to add new parameters in elogd.cfg to define the attribute name to use to retrieve the given name, login name and email from LDAP server.

By example :

LDAP email attribute = mail
LDAP surname attribute = id
LDAP givename attribute = gn

 

So users can define them according to their exotic LDAP schema ;-)

Hi Stefan,

I've seen that ELOG is build now with gcc-c++ now, so i tried to check rpmbuild script with all options. It seems that ldap api is different with c++ (quick search : https://www.openldap.org/lists/openldap-software/200706/msg00177.html) and elogd can not been build anymore with ldap support. :-(

Hi Stefan,

I don't find any howto to build elog under windows, so i tried to compile elog-latest sources with cygwin (packages gcc + openssl-devel + openldap-devel + make). 
It builds, i could start elogd.exe and connect to localhost:8080 ! 
I generate a zip with cygwin dll needed to launch elogd and tools. I think they could be enclosed (maybe the cygwin licence file have to be added ?).

Btw it should be possible to crossbuild it under Mac or Linux. The problem is to test it ;-). On Mac, you can use UTM to create a Windows VM to do the work.

Bye
Laurent

Hi,



We discussed on windows build some weeks ago and i tried to make one to check if it’s possible.

The result is in https://elog.psi.ch/elogs/Forum/69491

This could help you up to official new build.
