Hello,

I just gave it a quick try to the command line client, to see if I can use it to access our institution service. 

[root@host ~]# cd /tmp/
[root@host ~]# mkdir elog
[root@host ~]# cd elog
[root@host ~]# wget https://elog.psi.ch/elog/download/RPMS/elog-3.1.4-2.el7.x86_64.rpm
[root@host ~]# rpm2cpio elog-3.1.4-2.el7.x86_64.rpm | cpio -idmv
[root@host ~]# cd usr/local/bin/
[root@host ~]# ./elog --help
[root@host ~]# ./elog -h <hostname> -l <logbook> -u <myusername> <mypassword> -w last
"Message successfully transmitted, ID=-1"

Is that the expected output? I was expecting to see info about the latest message in the server.

Cheers,

Jose

Hello,

We used the Elog RPM binary installation method to install Elog. Our security scanners are complaining that Elog discloses the version information when you hit a missing page (404 error).  How can I hide this version info? Is there a snippet of code somewhere that I can comment out?

Any help is appreciated.

Dear all,

I had some difficulty to upload large files (>20MB) with SSL connection. I think it is also related to https://elog.psi.ch/elogs/Forum/68636

During debuging, I found that, when uploading large files, ssl connection is dropped since 'SSL_read' function returns -1.

But it doesn't alway mean broken connection. It may be "SSL_ERROR_WANT_READ".

I changed the "server_loop" function in the source code to "continue" when it is SSL_ERROR_WANT_READ. And it fixed the problem.

Here is my code.

## elogd.c "server_loop" function L30031

                        if (FD_ISSET(_sock, &readfds)) {
#ifdef HAVE_SSL
                          if (_ssl_flag){
                            i = SSL_read(_ssl_con, net_buffer + len, net_buffer_size - len);
                            if(i<=0){
                              int ssl_error=SSL_get_error(_ssl_con,i);    ## check ssl error code
                              if(ssl_error==SSL_ERROR_WANT_READ||ssl_error==SSL_ERROR_WANT_WRITE) continue;    ## if ssl wants more, continue
                            }
                          }
                          else
#endif
                            i = recv(_sock, net_buffer + len, net_buffer_size - len, 0);
 

I am ignorant about networking. Some experts on ssl connection would know a better way to deal with this problem.

Best,

I removed the version info from the 404 error, but you have to recompile elogd from sources. The fix will be included in the next RPM, but that can usually take a few weeks.

The <hostname> you have to actually replace with your real host name. Same for logbook, username and password. 

On my local test system I get (actual password hidden here with "...")

~$ elog -h localhost -p 8080 -l demo -u stefan ... -a Authort=SR -a Subject=test  test
Message successfully transmitted, ID=5

Hello,

I'm new to elog software and I could not find a solution to my configuration issue. I would like to setup a configuration file similar to MEG experiment's elog.

https://elog.psi.ch/elogs/meg/

I'm interested in creating similar to the structure: "General", "Collaboratoin", "Sub-groups (with sub-sub groups "Software", "Hardware" etc). I cannot tell if this was created by using Top Group feature.

Can someone explain how this design structure can be achieved?

Thanks,

Daniel
