[ILUG] problems running nessus

[Dave Burke]

<lazy mans update of what i did this afternoon>


22:18 < paul> Zefren: why not remove that /one/ module?
22:18 < paul> the one nessus open()'d and mmap()'d immediately before
segving.
22:18 < Zefren> paul: yeah...and then i removed another and then i
removed another and then i removed them all and copied one random one
 back...its the same prob
22:18 < paul> ah, nm so. :(
22:19 < Zefren> i have tried nuking it, and using the "lynx -source
                http://install.nessus.org | sh" method, to make sure it
was done thier way.
22:19 < Zefren> i tried the cvs version
22:19 < Zefren> i found a debian bug report which mentioed my prob
22:20 < Zefren> but it was closed with a "hey, works for me now, pls
close" msg, without any indication of a fix
22:20 < paul> odd.
22:20 < Zefren> it was on a deb/sarge box, so am gonna try it on woody
this evening to see if that makes any diff

</lazy>

And, as paul suggested, time for gdb.
