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.

Hi Finn,

I've just tested the same archive on new laptop with Windows 11. 
I unzip it and double-click elogd.exe file, bypass defender warning and the server is running.
To test, i open localhost:8080 on web client and it displays the demo logbook.

Btw i didn't test it as a service. What are the 2 libs you said it misses ?

Hi,

I use some CSS for each elog to resize column correcly and it seems that current ELOG version 3.14 available from EPEL for EL7 has a problem (maybe others also).

The browser console displays an error when loading ELOG logbook page (french locale ):

La feuille de style https:/xxxxx.xxx.xx/elog/MCO/1130_171749_REUNION_20221130_Q01.jpgelog-mco.css n’a pas été chargée car son type MIME, « text/html », n’est pas « text/css ».

It seems ELOG server send the css link with enclosure path (https:/xxxxx.xxx.xx/elog/MCO/1130_171749_REUNION_20221130_Q01.jpg) + css file (elog-mco.css) ?!?

I tryed to rebuild the last source from git under EL7 but it fails with LDAP libs (C++ regression already reported in elog:forum/69478). :-(

Thanks for help.

Hi Stefan,

It seems buildrpm should be updated to take care of cpp files. Plz replace "cp <blahblah>.c ..." by "cp <blahblah>.cxx ..." .

Also, uncomment the hostname test witch activates all authentification options by default. It should be done by adding options as follow : buildrpm ver rel -ldap -ker ...

By default, i can not build elog with LDAP.

After that mods, rpms are builded under EL7 (w/o LDAP support which is not useful for me).

Bye

Laurent

Update : i tryed with last git, w/o ldap support and it seems the problem is solved with CCS URL on same machine (just replace the elogd binary from EPEL by new one just build w/o LDAP support and fallback on File to login for testing).

So my problem is the error during build with LDAP auth (since using C++) :-(

Updated :

1. from google (https://www.openldap.org/lists/openldap-technical/201104/msg00030.html), it seems it's necessary to add before "#include ldap.h" in src/auth.cxx

#define LDAP_DEPRECATED 1

2. A cast must be added to src/auth.cxx:593 as already done somewhere with C++ commit :

         if (get_user_line(lbs, (char *) user, NULL, NULL, NULL, NULL, NULL, NULL) == 2) {
 

-> elogd builds now with ldap :-) .

I installed elogd binary and i could login and the css url problem is gone.

Thanks to update auth.cxx (2 mods) and buildrpm (2 mods) in git (sorry, no pull request).

NB : PAM can not be activated under EL7 with same type of error. I disabled the feature as i do not use it.

Hi,

I currently testing last ELOG version from git in a docker with LDAP activated (https://hub.docker.com/r/usinagaz/elog-ldap). The goal is to use it on Synology NAS server, associated with local LDAP server.

The reverse proxy is done by embedded DSM nginx, according to FDQN associated to ELOG service (elog.corp.com). In Docker, URL is set to elog.corp.com.

All is good, but when I post any enclosure in any elog post, the elogd exits and docker is automatically restarted. The browser shows an error 405 generated by nginx server.

Do you have any idea of the cause of this problem  ?

Thanks for help.

Laurent

Hi Giuseppe,

The new certificate files should be copy under ssl folder (/usr/local/elog/ssl or /usr/share/elog/ssl by example, closed to templates and script directories) in place of the embedded (autosigned) certificate files enclosed with ELOG source.

It seems that there is no parameter to set a custom path.

SSL = <0 | 1>
Turn on Secure Socket Layer transport. If SSL is on, one can connect via https://... to the elogd daemon. If the URL = directive is used, make sure to use https://... instead of http://... there. The ELOG distribution contains a simple self-signed certificate in the ssl subdirectory. One can replace this certificate and key with a real ceritficate to avoid browser pop-up windows warning about the self-signed certificate. The default for this option is 0.

Hi Daniel,

The RPM has been build for EL7 so SSL share libs should be different with the one provided by EL9. :-)

Try to rebuild from tarball source with enclosed buildrpm script (or with elog srpms if you find any : rpm -i elog*.src.rpm && vim ~/rpmbuild/SPEC/elog.spec # update build options as SSL/LDAP/PAM... && rpmbuild -bb ~/rpmbuild/SPEC/elog.spec ).
