I automatically install software on 3 machines in our lab, and at the end of the process, use eLOG to record relevant information for each machine (all running Windows XP) via the command line program elog.exe.  2 of the machines log their info correctly, but on third machine, I get the following error:

    Cannot retrieve host name: No error

The error is not very clear (i.e., the error is "no error"?), and furthermore, operationally, the error makes no sense to me, for the three machines are supposedly configured the same.  Additionally, the elog.exe used is stored on a network drive, as are the other batch files that all3 machines use, so it is not as a problem could creep in due to differing versions/configurations of files.

Just in case I am overlooking something, here's the command line invocation (I've X'd out sensitive information):

C:\>x:\@adat\tools\elog.exe -h max13 -l "Maxtee" -u xxxxxxxxxx xx1234   -a Tester=AULS_xxx_y    -a M
achine="Mercury 99"   -a "Module Type"=Controller   -a "Action Description=Configuration Change"   -
a Title="AULS upgraded to 1.2.7344 from [1.1.7343]."   -a "Card Count=998352"   -m X:\@ADAT\InterimP
F\MERCURY29.Blat_Msg1_PostBoot.TXT 1>X:\@ADAT\InterimPF\MERCURY29_eLog_CmdLineOutput1_(PostBoot).txt

Cannot retrieve host name: No error

Obvoiusly, there *must* be some configuration difference between the 2 working and 1 non-working machine, but I am at a loss to figure it out.

I am not sure which version of eLOG is being used, but the size of the elog.exe is 139,264. 

I suggest a new option be added to display the version information, or display the version info whenever eLOG is execute, or display the version info when "-?" option is used.

Stefan:

Thanks for the analysis and information.  Why am I not surprised that the "No error" came from Windows!? 

I tried some of your suggestions with the following results:

1.  Ping ==>= works as expected on the failing machine; that is, can successfully ping "max13"  I also can ping successfully in the reverse direction; that is, from "max13" to my "client" machine.

2.  NSLookUp ==>does not work on any of the 3 machines.

3.  Added the computer name "max13" to HOSTS file; ==> observed no change in behavior (i.e., still fails)

I did notice that on the 2 machines that function as desired that there is no anti-virus software installed, while on the non-funcational machine there is A-V SW installed.  I am able to bring up eLOG via the browser on the non-functional machine, so am unsure if the A-V SW is a factor; that is, why does ELOG via browser work as expected, but not via command line. 

QUESTION:  does command line ELOG connect differently than ELOG through the browser?

I ask this question for perhaps the A-V SW *is* blocking some port or whatever, and I will need to ask our IT department how to remove such a restriction.

Since both my machine and the Elog server PC are inside my company's "security zone", I am not running a firewall on my machine.

For what it's worth:  in trying to research the "No error" message, I did come across this information on MS's website; that is, their statement is:

The gethostbyname function retrieves host information corresponding to a host name from a host database.

Note  The gethostbyname function has been deprecated by the introduction of the getaddrinfo function. Developers creating Windows Sockets 2 applications are urged to use the getaddrinfo function instead of gethostbyname.

I tried to paste an Image from Clipboard into the CKEditor 4.5.1. Unfortunatelly, that doesn't work. I used Firefox, version 42. When I  looked in the javascript error console, it reported that "TypeError: b is undefined, ckeditor.js:1139:112". The variable  d.config.filebrowserImageUploadUrl could not be found.

I set the variable in the file ckeditor-config.js in the folder scripts, but that didn't solve the problem. As far as I can tell, Pasting Image from Clipboard does not work in this forum neither, but I don't know whether this is in purpose.

Pasting via the button "Paste from Word" works as it inserts a 64base formated image, but that's not what I'm searching for. Also normal upload of files works fine and puts the file in the correct folder (logbook/year/)

Updating CKeditor did work, thanks for the tip.

Hi Stefan,

The bad news is that elogd is still crashing even after disabling Image Magick.  The good news is that this time it was reproducible and I did obtain a
stack trace using gdb.  In this instance, a user was attempting to edit an entry he had just successfully posted.  In the crash shown below, he just Clicked
on "Edit" to edit the entry and then "Submit" without changing any text.  In the previous crash (that I don't have a stack trace for), he did actually try
to update the text of the entry.

Please let me know if there is any more information I can provide.

Many thanks,
Devin

The seg fault reported above seems to be related to a specific elog entry combined with sending email notifications.  When trying to submit changes to that entry while sending email notifications, elogd seg faults.  We can edit the entry before it and create and edit a new entry after 
it.  Trying to edit that one entry and send notifications, however, reliably crashes elogd.  If I check "supress email notification", elogd does not seem to crash.  I have replicated this on separate elog servers running both SL4 and on SL5.  To compare with SL4, here is the trace I see on SL5 (Scientific Linux 5).

Once I receive the OK, I will send you the actual file that stores the problematic entry.  Please let me know if there is anything else I can send you.

Many thanks,
Devin

Hi Stefan,

I hope I'm not bombarding you, but we seem to be seeing crashes in two separate scenarios.  In addition to the crashes I previously reported (editing a problematic entry and sending notifications), we 
have a (seemingly) separate means of crashing elogd.

One of our users connects from home using a satellite network (bursty and high latency).  Any time he attempts to upload an image from this connection, elogd crashes.  He has not yet seen any 
problems when using the same computer on site.  Here are the stack traces I've obtained, first on SL4, then on SL5.  Again, please let me know if there is any other information I can provide.

Thank you very much for your time and effort.

Sincerely,
Devin
