Hi Andreas. 

It seems I didn't fully understand the comment by Stefan when he said "Have you tried to connect directly to elogd and not going through Apache?". My bad.

elogd is a web service. You connect to it with a web browser. You don't pass arguments at startup of the service that refers to specific atrributes. I have no idea what you intend to do, you need to explain a lot more.

Hi Andreas,

I realize from your response that my question was not clear. I was not asking how to get it. Note that I am just a regular user, I am not the administrator of the service.

My question was about how to use it. From the man page, or from the explanation in the Administration Guide, it is not clear to me how to pass the same arguments I have been trying for /usr/bin/elog. For example, how to pass the list of attributes. I don't see a "-a" option for elogd. 

Thanks.

It is the default. If you install ELOG on your PC and run it, then every access will be directly to the ELOG web service. If you want to have Apache inbetween, it is some extra effort.

Nope. How? Is it documented?

  69063   Fri Nov 22 02:55:50 2019 Warning John S. Haggertyhaggerty@bnl.govBug reportMac OSX3.1.4Trouble on Catalina

I decided to rebuild elog 3.1.4 in Catalina (MacOS 10.15.1), XCode 11.2.1.  As in previous builds, I needed to add to the Makefile pointers to openssl:

CFLAGS += -I/usr/local/opt/openssl/include

LIBS += -L/usr/local/opt/openssl/lib

The make builds cleanly, no errors, no warnings.  After make/make install, elogd segfaults immediately.  I saw the same behavior with the version in gitlab.  I kept my (very) old build and was able to make install it without recompiling and it still works.

I'll crack out the debugger when I have a chance to get more information, but has anyone else seen this problem?

I am running the server on kubuntu 8.x, and have the same issue with chrome 1.x.
Is is possible the corporate elog server is running behind apache or in some
other proxy config while the one you are having issues with is being connected
to directly by chrome?

I just brought up the current head release of elog, and the problem is fixed. Looks like it 
was some sort of cookie issue IIRC the log entry.

So build a new elogd and you should be all set.

I'm actually still having this issue in Ubuntu and I'm running elog version 2.7.5. In fact, now it's worse in 2.7.5 than in previous version because sometimes I have to restart the machine to get elog working again.

Is there anything I can do to help you find potential bugs with Ubuntu?


What does "lsof -p pid" on the elogd process show, how about "strace -p pid"?

Since you are using elogd with an apache providing reverse proxy, I wonder if one of
the httpd processes isn't properly closing it's connection when it's done. That would
hang the elogd process since it's single threaded and non forking (IIRC).

Also why do you need to restart the box, does killing and restarting the elogd process not work?
When you kill elogd, does 'sudo netstat -anp' show anything listening at the elogd port?

Hello:

I am running release 2.7.8 of elog. I am using the cloning/syncing features
to maintain a backup/slave and at some point it stopped cloning the password
file.

Operating systems/software:

   master: ubuntu 10.4 using locally compiled elog 2.7.8-2278
   slave: solaris 10 using locally compile elog 2.7.8 without SSL support

A sample run (hostname edited - available by private email if needed) is:

  $../elogd -C http://host.example.org:8080/ 
  Overwrite local "elogd.cfg"? [y]/n:  y

  Remote configuration successfully received.

  Option "Mirror server = http://host.example.org:8080/" added to config file.
  Option "URL = xxx" has been outcommented from config file.

  Retrieve remote password files? [y]/n:  y
  Received invalid response from elogd server at http://host.example.org:8080/Discussion/

Running with -v doesn't produce any useful diagnostics as to what the invalid response is.

Trussing the process (again with host name editing) shows:

send(3, 0xFFBEE890, 93, 0)                      = 93
   G E T   / D i s c u s s i o n / ? c m d = G e t P w d F i l e  
   H T T P / 1 . 0\r\n C o n n e c t i o n :   C l o s e\r\n H o s
   t :   h o s t . e x a m p l e . o r g : 8 0 8 0\r\n\r\n
poll(0xFFBEC070, 1, 30000)                      = 1
recv(3, 0x011057B0, 251000, 0)                  = 119
   H T T P / 1 . 1   4 0 4   N o t   F o u n d\r\n S e r v e r :  
   E L O G   H T T P   2 . 7 . 8 - 2 2 7 8\r\n C o n t e n t - T y
   p e :   t e x t / h t m l ; c h a r s e t = I S O - 8 8 5 9 - 1
  \r\n C o n n e c t i o n :   C l o s e\r\n\r\n

If logged in as myself I go to http://host.example.org:8080/Discussion/?cmd=GetPwdFile
I do get the data so this looks like a password/authentication issue.

I have added Mirror user = rouilj to elogd.cfg, and it is present in the cloned elogd.cfg
but still no joy. I also copied the passwd file to the clone and made sure that it was being
successfully found and opened during the clone operation.

So where do I go from here in trying to troubleshoot the problem?
