Comment Re:Interesting, but compiler settings aren't optim (Score 1) 44 44

Well with the possible exception of those running gentoo, 99% of end users will be running precompiled software that has to be compiled for a generic cpu as the distributor doesn't know exactly what type of processor its going to end up running on.

At some point you have to trust someone, be it the distributor from whom you're getting the os, the manufacturer or reseller supplying the hardware or even the supplier of the compiler...

The only thing you can practically do, is ensure everything you use is available from multiple opposing sources... Something that's in use by both the us and russian governments is unlikely to be backdoored as both organisations have sufficient resources to perform the due diligence checks.

Most of the things out their targeting ssh are just trying to brute force accounts, so they don't care what platform your ssh service is running on... If they are successful in getting in its highly likely that they wouldnt have a payload compatible with your system... I've setup a few such boxes as honeypots just to see what people would do with them.

Comment Re:Gigabit speeds, though? (Score 3, Insightful) 118 118

Speedtest sites don't tell the whole story, especially at higher speeds...
Some of the speedtest sites are only on 100mbit themselves, even those on gigabit are usually sharing the bandwidth at their end... And then there's peering, the interconnect between your isp and the speedtest site might not have 1gbit of free capacity at the time your testing. The end devices (or the software running on them) might also not be up to the 1gbps rate - lots of cheaper gigabit nics can't handle wire speed, long or bad cabling, flash based speedtest apps etc.

I've had a box with 1gbps in a data centre for a few years now, and i can quite happily pull 1gbps doing torrent downloads and from some linux mirror sites, but i get a lot less from speedtest sites and many things download a lot slower because the other end or something in between can't handle it.

You need to test a variety of different things, and at different times of the day...

Comment Re:I sent mail... (Score 1) 617 617

Anybody with sufficient technical knowledge can fake an email to pass a casual user, but most people don't have that knowledge...

Just doing a spoofed SMTP transaction won't change the source ip that the message originates from, which will fail things like SPF checks and likely get flagged as spam (i.e. the recipient may never even see it)... And then there's things like S/MIME and PGP.

Faking a letter on the other hand may require a little effort as you describe, but anyone can do that... It's not really a lot of effort, doesn't require any specialist skills and would be extremely difficult (if not impossible) to prove it was fake.

I'm 33, and I listened to Neil for most of my life.
Old man, Heart of Gold, The needle and the damage done, Hey Hey my my, out on the weekend, Southern Man.
Those are all good powerful songs. He doesn't always sing perfectly in tune, but I find it acceptable since he really brings emotions to his songs.
