bb-rep.sh & bb-snapshot.sh 🔗 link

Hi all -

I'm running into a problem creating the availability report and the snapshot
on 4.3.0-beta2.  Every time I run either command I get an "Internal Server
Error".  The apache logs show "Premature end of script headers" and the
syslog shows that a buffer overflow was detected.

The system its on is a Ubuntu 9.04 64b server.

I have gone through the archives and based on what i did find i
double-checked permissions(all were good)..

Any ideas?

The other option I have is to try to recreate the report manually..  Any
ideas what datasets go into the report?

thanks!

I was having exact same error. I am running xymon version 4.4 beta. It is svn
revision 6311. I compiled it on ubuntu 10.04.

I see only google-chrome able to generate report.

It is failing with FF 3.6.3 on ubuntu 10.04, FF 3.5.8 on opensolaris
snv_134, and IE 8 on win xp

I went ahead and changed the CFLAGS on build/Makefile.Linux like this

  before:

  CFLAGS = -g -O2 -Wall -Wno-unused -D_REENTRANT $(LFSDEF) $(OSDEF)

  after:

  CFLAGS = -g -O2 -Wall -D_REENTRANT $(LFSDEF) $(OSDEF)

and recompiled using gcc version 4.4.3 and I don't see the "Premature
end of script headers"
any more. However, now I see a message in the browser, stays for a
quick second, right before
the report shows up. I can live with that pre-report message until I
find a substitute for -Wno-unused.

-Wno-unused does not show as a valid switch for gcc version 4.4.3

A: Because it messes up the order in which people normally read text.
Q: Why is top-posting such a bad thing?

After debugging together with some colleagues, I found a solution for
this problem.

In the source code of report.c and snapshot.c (in the map ./web) there
is a declaration in the main function: "char htmldelim[20];". In the
same main function we can find: " sprintf(htmldelim, "xymonrep-%u-%u",
(int)getpid(), (unsigned int)getcurrenttime(NULL));"

Because the size of "char htmldelim[20];" is not sufficient enough
(requires around 25 or so) this process will crash. I changed this char
value into 100 and after a "make && make install" command the issue
seems to be resolved!

Thank You! Very nice catch - good to have this done before the
4.3.0 release.

There is also a potential crash that can be induced by feeding the
report CGI a long "style" setting. I've fixed that as well in a
commit just now.
