[hobbit] Browser asks where to save bb-hostsvc.sh

[Marganne, Etienne]

I ran what you asked me to run. It directly generated a core file.
The output of the stuff:
./try: line 6:  6775 Segmentation fault      (core dumped)
~hobbit/cgi-bin/bb-hostsvc.sh

("try" is little script file which contains the command you aksed me to
type)

(no debugging symbols found)
Using host libthread_db library "/lib/tls/libthread_db.so.1".
Core was generated by `/home/hobbit/server/bin/hobbitsvc.cgi
--env=/home/hobbit/server/etc/hobbitserve'.
Program terminated with signal 11, Segmentation fault.

Sorry, I just read the other mails in this thread that you get a
"Premature end of script headers ..." which is an indication that the
bb-hostsvc.sh CGI crashed.

So - time to debug this. On your Hobbit server, run these commands:

    ulimit -c unlimited
    QUERY_STRING="HOST=YOURHOSTNAME&SERVICE=info"
    REQUEST_METHOD=GET
    SCRIPT_NAME="bb-hostsvc.sh"
    export QUERY_STRING REQUEST_METHOD SCRIPT_NAME
    ~hobbit/cgi-bin/bb-hostsvc.sh

Supposedly, this will crash - the last few linies it writes before the crash

are interesting. 

Hopefully, it will also dump a core file in your current directory.
Analyse this with gdb:

    gdb ~hobbit/server/bin/hobbitsvc.cgi ./core
and at the (gdb) prompt type the "bt" command:
    (gdb) bt

and send me the output.


Regards,
Henrik
