Dear Stefan,
Thank you for your comment. I successfuly compiled the latest elog from source code, and now elogd could work with SSL.
In fact, I reported the case of installation with rpm file. Maybe, the latest elog rpm doesn't support SSL, I guess.
The installtion with rpm file is easier to build the common environment, so I hope the next rpm will support the SSL.
best regards,
Hisataka YOSHIDA

When you compile elog from the soruces, you need the OpenSSL library to be installed. The CMake build process will then find it and include it in the compile process. When you use the "make" build process, you have to make sure that SSL is enabled there:
USE_SSL = 1
To install the OpenSSL library, you can do on most systems something like "sudo yum install openssl-dev" or "sudo apt-get install openssl-dev"

Hello.
I installed the latest elog (3.1.4-2) in CentOS 7, and it is working well without SSL.
When I enalbled SSL option (SSL = 1) in the "elogd.cfg", and tried to start the elogd, the message below was shown and failed to run.
SSL support not compiled into elogd
If I switched the elog to older one (3.1.4-1), I could successeed to run the elogd with SSL option.
Is there any other option required in the latest elog to run with SSL? Or is this bug in the latest version?
Thank you,
Hisataka YOSHIDA

Unfortunately I locallly don't have Webserver authentication, so I cannot check or debug. If you send me a diff that works for you, I'm happy to incorporate it.

Our setup uses "Authentication=Webserver" + no automatic user registration. Thus, logbook admins should add a user by clicking "Config" and then "New user". However, no matter what they fill in in the "new user " dialog, as soon as they hit "Save" an error pops up saying that their username (the admin one, not the new one) already exists. I found the following code:
int save_user_config(LOGBOOK * lbs, char *user, BOOL new_user)
{
char file_name[256], str[256], *pl, user_enc[256], new_pwd[80], new_pwd2[80], smtp_host[256],
email_addr[256], mail_from[256], mail_from_name[256], subject[256], mail_text[2000], str2[256],
admin_user[80], url[256], error[2000], sid[32];
int i, self_register, code, first_user;
PMXML_NODE node, subnode, npwd;
/* if we outsourced the authentication, use external username */
getcfg(lbs->name, "Authentication", str, sizeof(str));
if (stristr(str, "Webserver")) {
/* do not allow HTML in user name */
strencode2(user_enc, http_user, sizeof(user_enc));
} else {
strencode2(user_enc, user, sizeof(user_enc));
}
which seems to be the culprit: the admin user is logged using his/her Webserver (http_user) credentials and this overrides anything that he/she might fill in. If I remove the "Authentication" check then I can create a new user without problems. So, how to fix this? should the "Authentication=Webserver" check be extended with a self/auto registration check?

Today I succeeded with the help of L.JR to produce a new RPM which contains SSL, KRB5, PAM and LDAP support. It's uploaded to https://elog.psi.ch/elog/download/RPMS/elog-3.1.4-2.el7.x86_64.rpm

How can one add an attachment to a new or existing entry with py_elog?
E.g. if I want to upload an image.

elog server go to high CPU and hangs, posted by Stefano Lacaprara on Thu Feb 18 09:14:28 2021

Dear expert,
I'm running the latest git version of elog ELOG V3.1.4-395e101a on ubuntu 20.04.2.
I'm experiencing frequent hangs of the elog server: the status is always reported as running, but the web server is not responding.
The only hint I have of something strange is that the elogd process is using a lot of CPU (50-100%), the log do not show anything suspect
as far as I can see.
Has anyone experienced something similar or has any idea how can I start to debug the problem?
Sorry for lack of many information, but I don't know what to look at.
Thanks in advance

Usually a restart of the elogd server helps. If the problem persists, one of the logbooks might be corrupt. Try to disable one logbook at a time to figure out which one it is. Then
remove that one and set it up freshly.

here's the patch that I use to enable use creation and deletion in combination with Webserver authentication.
The idea behind the patch is that if the user logged in via "http_user" is an elog admin, then {s}he is allowed to save a random user configuration, including creating or deleting a user.
