 Very nice, thank you! Given that I also still have to test the fix you made for the crash problem with "shared" logbooks (I assume it's also present in 2244), I'll upgrade and report back (probably tomorrow).

 2244 is now running, and indeed, the "Size" attribute works now. Thank you!

By now, I've installed 2244 and ran some rudimentary tests. So far, I was not able to reproduce the crash anymore. Looking good!

icon5.gif   Strange problem with dates - need debugging help, posted by T. Ribbrock on Fri Feb 4 00:11:09 2011 

I have just installed elog 2.8.1 on my OpenBSD 4.8 server (I've added the necessary Makefile patch to "Contributions"). Everything seems to work fine, however, I ran into a very odd problems with the dates of the logbook entries: When I start a new entry, the current date/time is displayed correctly. When I submit the entry and look at it again, the date has changed to some value in 1996 . I've checked the actual logbook file and there, the entry has a Date line like this:

Date: Thu, 03 Feb 2011 23:53:28 -13049141
 

The "-13049141" looks very suspicious to me - but I have no idea whatsoever why this happens. I had elogd running with -v, but that did not give me any hints. Any ideas how to debug/resolve this would be much appreciated...

The problem is most probably related to the time zone. elogd contains a function:

/* workaround for wong timezone under MAX OSX */
long my_timezone()
{
#if defined(OS_MACOSX) || defined(__FreeBSD__)
   time_t tp;
   time(&tp);
   return -localtime(&tp)->tm_gmtoff;
#else
   return timezone;
#endif
}
 
from which you can see that there is a different behavior between different Linux flavors and OSX/FreeBSD. Maybe you need an additional
 
|| defined(__OpenBSD__)
 
if the pre-compiler directive __FreeBSD__ is not defined on your system.
[...]
 

 BINGO! That was it - thank you! I've added the || defined(__OpenBSD__) in the place you described above and now the dates are correct. While I was at it, I also had a look at what other ifdefs there are for FreeBSD and the only other one I found was also in elogd.c:

#if defined (_BSD_VA_LIST_) && defined (__FreeBSD__)

I'm far from being a C programmer, but I did some quick and dirty compile tests with various ifdefs set and apparently, _BSD_VA_LIST_ is not set on OpenBSD, so I guess that this statement does not need modification. I will keep my eyes peeled for strange behaviour, though...

Cheerio,

P.S.: One thing I noticed is that the OpenBSD variant of gcc throws these warnings when compiling elogd.c:

gcc -g -funroll-loops -fomit-frame-pointer -W -Wall -DHAVE_SSL -I../mxml -o elogd src/elogd.c crypt.o regex.o mxml.o strlcpy.o -lcrypto -lssl
/tmp//ccHhMZfy.o(.text+0xd2f): In function `int_vasprintf':
src/elogd.c:826: warning: vsprintf() is often misused, please use vsnprintf()
/tmp//ccHhMZfy.o(.text+0xae8): In function `xstrdup':
src/elogd.c:736: warning: strcpy() is almost always misused, please use strlcpy()
/tmp//ccHhMZfy.o(.text+0x13c7): In function `my_shell':

/tmp//ccHhMZfy.o(.text+0xf0ae): In function `el_correct_links':
src/elogd.c:5178: warning: strcat() is almost always misused, please use strlcat()

I'm not certain whether this is specific to this gcc variant, but I seem to remember that the OpenBSD folks added some extra warnings and suchlike as part of their overall code audit, so I thought I'd mention it.

icon4.gif   Odd bug with conditional and required attributes, posted by T. Ribbrock on Fri Feb 4 23:48:54 2011 

I just ran into an odd bug with conditional attributes: If I add a certain attribute to "Required Attributes", none of the conditionals will work anymore. I have tried to create a small logbook definition that will demonstrate the problem (the original logbook is more complex and uses two sets of conditionals, both of which will be disabled when the bug hits):

; General settings
Menu commands = List, New, Edit, Duplicate, Delete, Reply, Select, Move to, Download, Find, Logout, Help, Config,Admin
List Menu commands = New, Select, Find, Logout, Help, Config, Admin, Import, Download
Date Format = %d/%m/%Y
List conditions = 1
List display = Edit, Type, Created, StatusA, StatusB, Archived, Test Text, Public?

; Attributes
Attributes = Type, Created, StatusA, StatusB, Archived, Test Text, Public?
Required Attributes = Type

; Attribute Types
Type Created = date
Type Archived = date

; Options & Tooltips
Options Type = Type1{0}, Type2{1}
Options StatusA = Status-A-red, Status-A-orange, Status-A
Options StatusB = Status-B-red, Status-B-orange, Status-B
Options Public? = yes,no

; Conditionals
{0}Show Attributes Edit = Type, Created, StatusA, StatusB, Archived, Test Text, Public?
{1}Show Attributes Edit = Type, Created, StatusA, Archived, Test Text, Public?

The above logbook definition works. However, if I replace the Required Attributes = Type with Required Attributes = Type, Public?, the conditionals will no longer work. I can see the difference in the reactions of the browser - with the extra attribute, nothing happens when I change "Type". Without, the browser will spring into action and reload as soon as I change "Type". I've tested this with both Firefox 3.6.13 and Konqueror 4.4.5 on Kubuntu 10.04 as clients. Fortunately, this is not a showstopper for me, as it is not mandatory to have this attribute defined as required, but I find it a weird issue nonetheless.

Cheerio,

Thomas

P.S.: I'm currently running the latest SVN version of elogd on OPenBSD as I ran into the same problem as described in Message 66984. The above problem also happens with the 2.8.1 I was using before. Some feedback: The SVN version compiled and ran without any further intervention on OpenBSD - very nice!

Your problem is the "?" in the attribute Public?.  Attributes may only contain ordinary characters. Unfortunately I did not document this so far. Therefore I put some fix in SVN revision 2387 which allows your attribute Public?, but I'm not 100% sure if this works in all places. The safest is just to remove the question mark.

 Thanks Stefan, I'll try that. It's strange, though: At work, we're running 2.7.6 (and have used older versions in the past) and we have several logbooks with each at least one or two attributes with '?' and never had a problem with conditionals. Hence my surprise when this suddenly hit me with 2.8.1+ at home. Removing the '?' would be quite some work, as I'd have to change all logbooks and the associated data (the latter could probably be done with "rpl", I hope). I'll think about it.

icon5.gif   kerberos authentication , posted by Szu-Ching Peckner on Mon Aug 20 21:48:08 2012 

Hello, I have

authentication = kerberos

kerberos Realm = xxx

I ran tcpdump and know elogd server did attempt to contact kerberos server. I could run kinit username@realm_name, and klist shows my ticket fine. 

I receive "kerberos error 256: Decrypt integrity check failed. Please check your kerberos configuration" when I entered my password wrong purposely on login page.

I receive "Invalid user name or password!' when I entered my correct password. 

Please advise.

I forgot to mention, I also have Password file line in elogd.cfg file. Because without password file line, I wouldn't get login screen. I know my test account is not in the main.pwd file. I believe elogd does go to kerberos server to compare password. I just don't get why I get invalid username and password when I entered correct password, while kerberos error (expected) when I enter wrong password.  

Authentication = Kerberos

Kerberos Realm = xxx

Password file = main.pwd
