Raspbian stuck at boot (at NTP server)

Hi, Today I tried to reboot my raspberry pi for a long time. During boot the system halts at "starting NTP server". Pressing ctrl+c or trying to open different consoles did not work. I disconnected all usb/lan and rebooted (ctrl+alt+del still works). The system now halts with an error message that s...

Re: PHP-MYSQL server to RasPi

Apache and mysql works just fine. I would prefer lighttpd because its faster with less resources.

Re: Temperature sensor

Yes, a 2 degrees Celsius resolution seems imprecise. but sensing precise temperatures is a lot harder than people realise! However the TMP102 has four times that resolution (0,5 degrees). You won't easily find a cheap solution with a better resolution. Also note that up to eight LM75 sensors or two...

Re: Samba Performance

do you guys run your pi 24/7 as a samba server? i've been wanting to order one for so long. but just read about the 1.8V LAN rail issue. And I'm not that keen, if its not stable or wont be stable for long. any experiences with stability? 24/7 operation is that ok? what kind of setups? are your LAN ...

Re: Temperature sensor

A breakout board such as http://www.hobbytronics.co.uk/sensors/temp-pressure/tmp102-temperature-sensor may be easier to handle. Seems a good options! It's has a much better accuracy and easy soldering. So if i connect the 3.3v, ground, sda, scl pin's directly to the raspberry pi this would work? I ...

Temperature sensor

Hi, I'm looking to buy some temperature sensors for my Raspberry Pi. I don't have much experience with buying sensors. What interface should I use? I2C, usb-serial, something else? I was thinking of I2C because i would not need any extra devices. This is wat i've found allready: LM 75Temperature Sen...

Re: Samba Performance

8-9megabyte/s with ext4 external hd (3.5"). Off course when transferring small files the speed drops. do you get this speed on reading or on writing data to the raspberry? I got around 4,5megabyte/s on reading and just 3megabyte/s on writing with an ext4 external hd. I've then added the following l...

Turn off screen

Is there a command that turns off the screen?

Something like: xset dpms off

But for the raspberry pi, in debian, running from the terminal.

OK led = off

Hi,

Can somebody explain the meaning of the ok led? Yesterday I rebooted my raspberry pi and since then the ok led is off.

Everything seems to be working on the raspberry pi. Is there some log file i can check?

mmcqd/0 using all the resources

Hi, I'm running debian on my raspberry pi. When I run the command 'top' the process mmcqd/0 is using allot of resources (also kswapd0). Does this mean that I'm using to much memory? I currently have no swap enabled, is it wise to enable swab on my sd-card ? Or will this shorten the life time to much?
