<Mjolnir> Ok - I'm helping Skeelow on a private channel. He's got a mess and it's handy to be able to paste w/o flooding things or messing with pastebin.
<AlexB> ^DX^: Get courier-imapd, which also has a POP3-server.
<^DX^> according to inetd.conf I already have pop3/pop3s/imap2/imaps running
<^DX^> pointing at /usr/sbin/popd
<^DX^> how do I add users?
<pb24ss> adduser? ldapadd? how are your users added?
<pb24ss> errr managed>
<^DX^> adduser
<pb24ss> so add system users for your pop accounts
<^DX^> how do I disable shell access though?
<pb24ss> change their shell to /bin/false or /sbin/nologin or something valid from /etc/shells
<pb24ss> vipw
<pb24ss> or chsh
<^DX^> thanks a lot
<pb24ss> np
<ruffe> anyone that know something about enabeling DMA in linux?
<pb24ss> hdparm
<Qwell[]> -d
<pb24ss> -qwell
<Mjolnir> ruffe - hdparm works, but some distros have an option in /etc/sysconfig to do it permanently.
<ruffe> HDIO_SET_DMA failed: Operation not permitted
<Mjolnir> ruffe - do it as root.
<ruffe> was rot
<ruffe> root
<Mjolnir> May not be supported by the driver or some such then. What device did you try to set it on?
<ruffe> hdparm -c1d1X66 /dev/hdc
<Mjolnir> Try each option one at a time and see which ones work
<ruffe> ND-6500A
<ruffe> it's d1 that don't work
<Mjolnir> What controller are you using? Any idea?
<Qwell[]> ruffe: does -d by itself say it's off?
<Qwell[]> no reason to chase a problem that doesn't exist in the first place
<ruffe> 915GM
<ruffe> ?
<ruffe> Qwell, and by that you mean?
<Qwell[]> hdparm -d /dev/hdc
<ruffe> doesn't work
<Qwell[]> umm
<Qwell[]> it should
<Mjolnir> What does hdparm /dev/hdc return?
<Mjolnir> Normally -d is included in that list
<ruffe> /dev/hdc:
<ruffe> IO_support = 1 (32-bit)
<ruffe> unmaskirq = 0 (off)
<ruffe> using_dma = 0 (off)
<ruffe> keepsettings = 0 (off)
<ruffe> readonly = 0 (off)
<ruffe> readahead = 256 (on)
<ruffe> HDIO_GETGEO failed: Inappropriate ioctl for device
<IdiotStic> NO PASTING
<ruffe> k
<Qwell[]> no pastel either
<IdiotStic> ruffe: use uuoc.com or pastebin.com if it's more than a line or 2
<Idle`> Mjolnir: theres a lot of lakes that we can use... the problem with the great lakes is that it gets really messy during bad weather... :S
<n00m> hey thanks for that set ruler tip...
<n00m> vim doesnt support it nvi does which i managed to smuggle onto this rhe box nicely
<bougyman> what version of vim doesn't suport ruler?
<Qwell[]> bougyman: 0.96
<bougyman> heh
<jjshoe> qwell[]
<jjshoe> it's going to cost me about $100 to fly home again in a few weeks :P~
<Mjolnir> YEah. We just need one a few miles long
<Mjolnir> However we can avoid bad weather.
<Idle`> theres a lake near me, but thats a long ways for you... and we're limited to a 2-3 month test window
<Idle`> and theres no sufficient landing space
<Idle`> I've been to the great lakes... theyre not very calm
<Mjolnir> Yeah
<Mjolnir> There are places around here we could theoretically test.
<Idle`> we should find another one, perhaps closer to you... where do you live? somewhere where we have > 3 months of test time
<Idle`> yea
<Mjolnir> I'm much more familiar with getting FAA waivers than trying to manipulate whatever the Canadian aviation authority is.
<Idle`> canadian aviation == uhm, whats a plane?
<Idle`> hehe
<Mjolnir> I live in central Virginia. Look for Roanoke, VA on Mapquest. I'm thinking that NC has a flatter area available though.
<Idle`> FAA does a lot of control in canada too, but still
<Mjolnir> I'd have to ask around to find what it takes to get waivers up there.
<Mjolnir> Probably it's a bigger mess than here.
<Idle`> yea, agreed
<Mjolnir> I know their model rocketry regs are stricter.
<Idle`> plus, more tinker time down there
<ruffe> i'm not able to enable dma, is it possible that i don't have chipset driver installed?
<Mjolnir> Yeah. I'd get with the NC rocketry crowd and work with their waivers. That'd give us 8000 feet to do whatever the hell we wanted and a 4 hour window to 12000 feet.
<Mjolnir> ruffe - quite possible, but there are other reasons as well.
<Idle`> thatd do it
<Idle`> thatd be enough for 1 attempt at least
<ruffe> i can't play DVD without dma
<Idle`> http://maps.google.com/maps?f=q&hl=en&q=Roanoke,+VA&ie=UTF8&ll=34.685734,-76.545868&spn=0.336513,0.723724&om=1
<Idle`> hmmmm
<n00m> bougyman as far as i can tell standard redhatish vim-minimal rpms do not support ruler :(
<Idle`> probably too windy since its the ocean, but those sounds look like they could block a significant ammount of waves
<Mjolnir> It got the wrong place.
<Idle`> no no, just scrolling around
<Mjolnir> Hold...
<Mjolnir> No ocean anywhere close.
<bougyman> vim-minimal would be bad
<Idle`> jacksoneville NC, out at the ocean
<n00m> yes its horrid and i need the character position to write files that db2 can eat up
<Mjolnir> Our usually flying area is around Whittakers, NC.
<Idle`> ah, haha
<Mjolnir> Also, spring and fall we fly at Battle Park, Va
<Mjolnir> But they have crops in during the summer.
<Idle`> yea, we just need something out of a flight path that we can get clearence
<Idle`> 8000 ft would be OK
<Idle`> we would need to test every component, 1 by one...
<Idle`> perhaps even test fire the rocket off a cesna to check the launch mechanism, and see how much it pulls the clamps (if at all)
<Idle`> we need to put together a professional looking research package to see how 'possible' it is, so we can start finding sponsors
<Mjolnir> I could ground-launch the rocket.
<Idle`> yea,
<Idle`> I'm thinking super-stubby wings, that are decently long, just so it retains altitude
<Mjolnir> In fact, I'll talk to my club and maybe we can put the rocket together over the next few months. Actually, Jim probably has a couple we could use right now.
<Idle`> there we go ;0
<Idle`> :)
<Idle`> the real $$ will be in the launch vehicle
<Mjolnir> Remember this - rockets like the sidewinder missle etc. fly horizontally with standard fins.
<Mjolnir> Doing this is not difficult.
<Idle`> I dont just want to cheat, and strap a clamp onto a cesna... :P
<Idle`> yea, thats true :)
<statickao> when upgrading a kernel can i use the old config file to compile or do i need to make a new one
<Mjolnir> I don't want to launch off of a real plane. Too much can go wrong.
<Idle`> for the first prototypes, well do standard fins, but when we get a return mechanism well need wings
<Mjolnir> statickao How much of an upgrade?
<statickao> 2.6.16-r9 to 2.6.17-r4
<Mjolnir> Yeah. If you want to glide down. However some of the NC group already has this.
<Idle`> well, yes and no. :S with a real plane your right there with it to fix malfunctions, but you can take down your own plane... I think it would be much nicer if it was from an RC plane
<Mjolnir> Oh, you can probably pull the config file then and do it. It's stored as /proc/config.gz
<statickao> is it safe?
<Idle`> statickao: in the new linux source dir, theres a util that can extract it if theres no /proc/config.gz
<Idle`> statickao: oh yes, very safe
<Idle`> statickao: cp /proc/config.gz .
<Mjolnir> As safe as building the kernel.
<Idle`> gunzip config.gz
<Mjolnir> Idle` If you ever get down here I'll have to show you some RC boost gliders - go up like a rocket and then use RC control to glide back down.
<Idle`> Mjolnir: for now, I think a parachute return is going to be fine
<Mjolnir> Yeah, same here.
<Idle`> yea, I've seen those
<Idle`> heres one problem tho
<Mjolnir> Need GPS tracking though. We'll have stuff coming down all over the place.
<Idle`> it needs to decelerate... it doesn't have gravity for that...
<Mjolnir> Oh, it'll decelerate. Don't worry about that.
<Idle`> we're going to need some kinda airbrakes otherwise the chute will tear
<Mjolnir> Actually, no.
<Mjolnir> Drag at that kind of speed is horrific. turn off the engine and you'll drop down to 200-300mph very rapidly.
<Idle`> ah, :)
<Mjolnir> Then a standard drogue and main recovery will work just fine.
<Idle`> well, I knew at high speed
<Idle`> but I thought at 6 -> 300mph it would mostly cruise
<Idle`> yea, thatll do it :D
<Mjolnir> Actually, after all the fuel is burnt, terminal velocity will probably be closer to 150
<Idle`> we want it to decelerate before it looses too much altitude, otherwise we're going to end up with a lawn dart
<Mjolnir> Main thing is we won't have much in the way of weight. Where things get complex is when you start trying to carry a warhead like Hezbola. The forces involved in doing that are a lot larger.
<Idle`> yea, thats true
