That worked well when elog was started by root (and falling to user elog),
but later, I moved all the elog tree to /home/my_name/.elog,
(I'd like to start it only when I'm logged, it's only for personnal data)
changed all the attributes/permissions ($chown -R my_name:my_group .elog)
and none of these commands still works ! I use the -x option to allow
shell substitution.
More surprisingly, even the fixed text doesn't work (???) |
First of all, you could use
Preset R-Date = $date
instead of the shell command. Secondly, the command
Preset $text = $shell(whoami && set)
is wrong. Replace it by
Preset text = $shell(whoami && set)
without the "$".

There is a good reason for that. If you run elogd as root, this can open a dangerous hole into your system. If there would be any bug in elog, an attacker could gain root access easily. By falling back to a non-root user, the damage can be minimized. As a precaustion, elog falls back to Usr and Grp "elog" if that setting is missing in the config file.
When you run elog under your user name, this fallback is not necessary. Why you got the message 'Falling back' is a mystery to me. I tried to reproduce that, so I run under a non-root account with following config:
[global]
port = 1234
[demo]
Attributes = Subject
Preset Subject = $shell(date +"%Y/%m/%d %H:%S")
and correctly got the date in the "Subject" field with ELOG V2.6.1-1640. |

I'm sorry ; even with this correction, none of the preset strings created with
a substitution mechanism (shell or built-in) works when elogd is started as
ordinnary user. I've tried the same config file /home/gv/.elog/elogd.cfg :
port = 8080
Language = french
Main Tab = Accueil
Usr = gv
Grp = users
Logbook dir = /home/gv/.elog/logbooks
[gauthier]
Self register = 1
Password file = passwd
Theme = default
Comment = Logbook personnel
Default encoding = 1
Time format = %a, %d/%m/%Y %H:%M
Attributes = Type, Statut, Priorité, Sujet, R-Date
Preset R-Date = $shell(/usr/bin/date +"%Y/%m/%d %H:%S")
Preset text = $shell(whoami && set)
;Preset text = Blablabla
;Preset text = $date
Start page = ?rsort=Record date
List display = R-Date, Type, Statut, Priorité, Sujet
Options Type = Divers, Lectures, Musique, Aca, Finances, Santé
Options Statut = A faire, Exécuté, Journal
Options Priorité = 0, 1, 2, 3
Preset Priorité = 0
Extendable Options = Type
Thread display = $sujet ($entry time)
Required Attributes = Type, Sujet
Page Title = ELOG - $subject
Reverse sort = 1
Quick filter = R-Date, Statut, Type
Sort Attributes = Priorité, R-Date
Started via root (# /usr/sbin/elogd -c /home/gv/.elog/elogd.cfg -x), it works,
but via "gv" ($ /usr/sbin/elogd -c /home/gv/.elog/elogd.cfg -x), it doesn't.
