Except for the fact that it isn't at all in the FHS which already has enough problems with it being very open to interpretation (and sometimes extended... RHEL, what's/net, how does it differ from/srv). Symlink farms mean that you're doing something wrong.
I've already seen distros symlinking/srv/httpd to/var/www, because that's where apache has been for the last fifteen years! If you have a place for servers, then, what belongs in/opt and what belongs in/srv? If it's a network server, does it go in/opt,/srv or/net? If it's over NFS, does it go in/export/home,/data/home or/home? You cannot separate directory structures by use because much of the data we have has multiple uses.
IIRC, nessus does network security scans that check for holes in software on the network (missing patches, etc.). You could do a pen. test using a live CD like Arudius, INSERT, PHLAK, etc. Check out the security live CDs at Frozentech's Live CD site. Many have the nessus package on board.

Were you able to tell if the cause was actually VMWare itself or the cores ping-ponging the cache? I've got a dual socket, eight logical core Xeon box at work, and I always suspected that the SMP performance was off, but I could never narrow it down to where I could say for sure that it was VMWare (and say, not a saturated front side bus).
This was my idea while using iSCSI with VB (except using LVM snapshots, but same idea - the backing stores are actually 20GB 'dd' raw files for performance and flexibility), except that it's a pain to snapshot the whole RAID array/zpool for a single VM, and it's just one more PuTTY session that I have to leave open to execute a snapshot every hour or so. Granted, ZFS has much more flexible options than LVM, but it would be great to have an integrated interface accessible from the GUI. Nothing breaks my concentration better than alt-tabbing and desktop switching to find a window/app.
I know I'm nit-picking, but it really was a turn off for me when I realized that I'd have to repartition and setup LVM for the same functionality that I already have on VMWare on both Windows and Linux. The reason I started to look at VB in the first place was for its native iSCSI support, so that I didn't have to deal with mounting directory structures on two desktops.
Well, from time to time, I use the "()" notation as a subtle "RTFM" if I'm mentioning something obscure or complex. For me, it's kind of like linking to wiki when the discussion of something is well out of scope for the topic on hand.
When you see the "()"s, you know exactly where you get more info on the subject. I think this is somewhat usual for mailing lists and multiple CC'ed emails where you have people of varying degrees of experience. I think it really does help S/N ratio, IMHO.
And then do that again when you uninstall and are left with dead entries because the uninstaller can't handle a task so difficult as finding its executable in the start menu. That is, if it doesn't blow up upon not being able to find it, and leave you to manually pull the shrapnel from the registry ('cause it'll leave its entry in "Add/Remove Programs" and then not run when you try to remove it). And as a bonus, if you update the program, you get to this twice!
I'd be surprised to hear that it beats out Xen! Isn't Xen a lower level hypervisor as compared to the VMWare ESX kernel hypervisor? Although, I have heard that ESX has been sped up quite a bit recently - I just assume that whomever is riding closest to the hardware wins the speed race...
For me, the Big Win is native iSCSI support.
I was about to fire up a Xen solution on RHEL-5.2 tomorrow. I've got an eight logical core Xeon box that my boss and I were thinking about hosting a few VMs on, so this throws me for a loop now!

Would you be referring to BSD, or LSD? *Sorry, I couldn't help myself when I read that!*;)
Would it be the Ford & Topp version of "Data Structures with C++ using STL" like the old beat up version that I'm looking at on my shelf? Worth its weight in gold and has a permanent place on my shelf! Good point.
I go to a decent school, Kutztown University (PA, USA), and as a freshman I was expected to ssh to our Solaris box to write C++ code using vi (or emacs, if you like that kind of thing). Sophomore year was SPARC assembly, C, Java. Junior year for me (give or take a few semesters, I tend to do poorly in non-CS courses) was functional languages with ADA95, AI using PROLOG and LISP, Operating Systems we got to choose our languages (I used Perl and Java), and a little more lower level C stuff, with the usual maths and theoretical obligations.
Although, we have three tracks (they might as well be majors, they decide your course path from your second semester on mostly), software development, IT (traditional CS), and networking/administration (they get to play with all the cool hardware, I'm kinda' jealous). I'm doing software development, but I think that the other paths are equally skewed so far as learning curve steepness.
Time does funny things to the memory. Perhaps I'll feel the same way thinking back on the "good 'ol days" and how I used to use a magnet and a steady hand to write to a whopping 1 TB harddive, back when they were still mechanical and magnetic. OK, I'm getting off your lawn now.:)
Yeah, no doubt, I just decided whose chipset will be on my next wireless board. Just FYI, hardware supported by these drivers (shamelessly ripped from wireless.kernel.org):
And I'm sure they've got their heads so far up their butts, they'll be surprised when the masses shout back, "Cut the TV service, we'll take the internet package!" They. Just. Don't. Get. It.
I have an example of that from just the other week. Take it as you will, but I found it to be a trend that emerges the more I talk to techs from both the open source and closed (be it developers, admins, general IT guys).
The other week I mentioned to someone (a studied but not certified MCSE) that RHEL 5.2 not only ships with Xen support out-of-the-box, but has a full LDAP server. "Oh? LDAP... so it does Active Directory?" was his reply. I fumbled over my thoughts and managed to get out, "let me see if it has the schema" and got the feeling that he didn't know that LDAP has many uses that aren't Active Directory. I RTFM (something he doesn't seem to like me doing, as I often say "gimme' a minute to read the manual", look up the pertinent information and present it much to his indifference, while I usually wonder how many hours will pass before he'll ask me a question whose answer will rely on the understanding of the information I'm currently presenting) and say "Yeah, it looks like it does have the schema for it", to which I was given a prompt, "Well, that's a long way off for us."
True, but wouldn't it be nice if we had some kind of place to put that customer list and information that has redundant information covering several MB of poorly named ("Copy of Copy of temporary people list.xls")Excel spreadsheets? I've mostly given up on even presenting the possibilities out there to this person because they are locked in this mindset of a vertical, pre-integrated, pre-configured, program set (stack, as the lingo goes, apparently). He doesn't know that AD is a schema with extensions for an LDAP/X.500 DIT, and refuses to go further than "Microsoft does that, it's called...". This same thing has happened over and over with this person, and I always get a dismissive attitude when I say (as a software development major) "I could program that for you, it's just library x interfacing service y with z GUI, and on sourceforge there are twenty projects that do specifically that."
It's like the very idea that you can learn the underlying technologies and interface them at certain layers, to create a more powerful and better suited, is so foreign to closed source that the very suggestion of doing so is such that the mind recoils in horror.
Rather, the idea is that you buy something that somewhat fulfills your needs (and includes the kitchen sink you've never wanted) and then work around its limitations until it is EOL'ed and you upgrade (backwards compatibility optional). This, of course, is preferred because "... we don't know how it works..." for singular values of 'we'. Note that regardless of how much technical data from documentation, demos, proofs of concepts, emails from authors regarding our ideas, and source code is provided to debunk this notion, 'we' will never know how it works and will have to deal with this inconvenience until someone markets a solution with a heavy price tag to do it. No, 'we' won't ever know how it works because 'we' don't care and couldn't be bothered to step out of our comfort zone and do our homework. Doubly so if our homework entails learning about something that isn't absolutely necessary to understand what we're studying.
This, of course, is my personal experience and a general trend I've noticed. Take it with a grain of salt, knowing that there will be cases where the opposite is true.

OK, that actually makes sense. I've always mounted network file systems under /mnt/hostName, but /net is a better solution. Thank you!

Yeah; I sleep well at night knowing my secrets are safe.
