Revisiting Linux Part 1: A Look at Ubuntu 8.04

Test Setup
Since this first part is more about the applications and the user experience than the performance, we’re going to keep the benchmarks short. Along with looking at 9.04, part 2 will focus on a greater level of benchmarking, particularly graphics benchmarking.
For now we’re going to be taking a look at general situations – encoding, compression, file operations, etc. Because there’s a lack of a solid benchmarking suite that’s compatible with both Windows and Linux (e.g. PCMark), we don’t currently have a way to benchmark multitasking scenarios. So this is largely a look at single application performance.
Due to some initial issues with the 64bit version of Hardy, all of the following testing is done of the 32bit versions of Hardy and Windows Vista respectively. Future articles will be done with 64bit operating systems.
Our test setup was as follows:
| Software Test Bed | |
| Processor | Intel Core 2 Quad QX6850 (3.00GHz/1333MHz) |
| RAM | G.Skill DDR2-800 (2x2GB) |
| Motherboard | Gigabyte GA-P35-DR3R (Intel P35) |
| System Platform Drivers | Intel 8.1.1.1012 |
| Hard Drive | Seagate 7200.11 500GB SATA |
| Video Cards | 1 x GeForce 8800GTX |
| Video Drivers | NV ForceWare 186.18 |
| Power Supply | OCZ GameXStream 700W |
| Desktop Resolution | 1600x1200 |
| Operating Systems | Windows Vista Ultimate SP2 32-Bit Ubuntu 8.04 "Hardy Heron" |

...sorry, I think it's Alt+F2 by default. I'm talking about the 'Run Command' dialog.Eeqmcsq - Wednesday, August 26, 2009 - link
Oh, yes you're right. I stand corrected.sprockkets - Wednesday, August 26, 2009 - link
Ubuntu doesn't ship with the firewall on eh? Weird. SuSE's is on, and that has been the default for quite some time. GUI management of it is easy too.clarkn0va - Wednesday, August 26, 2009 - link
For incoming connections I don't quite grasp what good a firewall will do on a system with no internet-facing services. With no open ports you stand little to gain from adding a firewall, and any internet-facing service you might add, well, you don't want to firewall that anyway.I can see two theoretically plausible arguments for a host-based firewall, but even these don't really stand up in real-world use: 1) a machine that has open ports out of the box (I'm looking at you, Windows), and 2) for the folks who want to police outgoing connections.
In the case of the former, why would we open ports and then block them with a firewall, right out of the box? This makes as much sense to me as MS marketing their own antivirus. Third-party firewalls were rightfully introduced to remedy the silly situation of computers listening on networks where they shouldn't be, but the idea of MS producing a host-based firewall instead of just cleaning up their services profile defies common sense.
In the case of outbound firewalling, I've yet to meet a home user that understood his/her outbound firewall and managed it half-way effectively. Good in theory, usually worse than useless in practice.

Just because a port/service is open, doesn't mean you want it open to the whole world.Examples:
SMB
NFS
VNC
RDP
SSH
Web (intranet sites, for example)
And the list could go on... and on and on and on, really.
Also, it's erroneous to assume that only 1st party software will want to open ports.
And that is to say nothing of the possibility of ports being unintentionally opened by rogue software, poorly documented software, naughty admins, or clumsy admins.
Host-based firewalls help with all of these situations.

Windows firewall doesn't filter by source. In other words, if you want SMB or any other service open to some peers and not others, Windows firewall can't help you; you'll need a more sophisticated product or a hardware firewall for that.I'm not saying there's no case for host-based firewalls, I'm just saying it's pointless for most users out of the box, where Ubuntu doesn't need it and Windows should be looking at fixing the problem of unneeded services running, rather than just bolting on another fix.

"I can see two theoretically plausible arguments for a host-based firewall, but even these don't really stand up in real-world use"That sounds to me like a claim that there is little or no case for a host-based firewall; at least, that's how I interpreted it.
"Windows firewall doesn't filter by source. In other words, if you want SMB or any other service open to some peers and not others, Windows firewall can't help you"
That is incorrect, and you should check your facts before making such statements. The Windows Firewall can filter by source. Any firewall exception that is created can be made to apply to all sources, to the local subnet only, or to a custom list of IPs and subnets.
The firewall in Vista and Windows 7 goes a step further, as it is location aware. Different ports and services are opened depending on the network you're plugged into, as exemplified by the default behavior of treating all new networks as "Public" (unknown and untrusted) until instructed otherwise.

"The Windows Firewall can filter by source. Any firewall exception that is created can be made to apply to all sources, to the local subnet only, or to a custom list of IPs and subnets. "In that case I retract my assertion that an out-of-the-box firewall makes no sense in the case of Windows.
As for Ubuntu, or any other desktop OS having no open ports by default, I still see including an enabled firewall by default as superfluous. Meanwhile, firewall GUIs exist for those wishing to add them.

...not enough pictures. admittedly my interest additionally waned when i read the newest ubuntu isn't be reviewed.philosofool - Wednesday, August 26, 2009 - link
I'm not done with this article, which I'm loving. However, there's a grammatical/spelling quibble that's driving me nuts: "nevertheless" is one world.
