<font face="Georgia">Hello Mathias,<br>
<br>
I got the same problem when I played with Polygraph installed on
Debian4.<br>
For older kernel version (2.4) there was some trick to modify kernel
headers to convince Polygraph for more file descriptors.<br>
</font><font face="Georgia">Unfortunately I've found nothing for 2.6
kernels.<br>
<br>
</font><font face="Georgia">It seems that during compilation and
runtime Polygraph is not taking these "ulimits" but some kernel headers.<br>
I decided to use FreeBSD because Polygraph was written on this
platform. With FreeBSD of course problem is gone.<br>
<br>
On the other hand... it would be nice to use Polygraph with other
platforms too... Alex?<br>

<pre wrap="">I am trying in vain to increase the number of file descriptors that web polygraph uses:
when starting polyctl, I get the following message:
== snip ====
000.01| FDs: 65535 out of 65535 FDs can be used; safeguard limit: 983
== snip ====
=> Why does the safeguard limit stay at such a low level?
Additional information here:
============================
Limits:
-------
ulimit -n => 8192
ulimit -Hn => 65535
cat /proc/sys/fs/file-max => 205300
System information:
-------------------
OS: Ubuntu Linux, version: gutsy
Kernel: 2.6.22-14-server
g++ version: 4.1.3
CPU: Dual-Intel Xeon CPU 3.20GHz
polygraph information:
----------------------
version: 3.0.6
configured: with option: --without_ssl
=> when running ./configure, these might (?) be the interesting lines:
checking for set_new_handler... no
checking Default FD_SETSIZE value... 1024
checking Maximum number of filedescriptors we can open... 65536
I am clueless. Are there other parameters to check/change?
Thanks in advance for a hint!
BTW: web polygraph really rocks! Although I had a quick look on the application before, I just realized how powerful the whole suite is!
