Fequently Asked Questions
General
I have found a bug, where can I report it?
You can report it on the bugtracker.
Alpine freezes 1 minute when booting from Compact Flash, how can I fix?
Append nodma to the append line in syslinux.cfg.
How can I contribute?
You can contribute by using the software and give feedback. You can contribute by helping with the documenting your experiences using this wiki.
Your contributions are highly appreciated.
How do I remove the CDROM?
Since the modloop loppback device is on CDROM its no just to run eject. You need to unmount the modloop first. Unmounting both the modloop and the cdrom in one step can be done by executing:
/etc/init.d/modloop stop
Then its possible to run eject to eject the cdrom.
Audio
How do I play my .ogg/.mp3 files?
First, the sound card should be recognized (you must have /dev/snd/***** files)
sox, mpg321, mpg123, oggplay, etc all use the oss sound driver, while Alpine uses ALSA drivers. So you need to load the snd-pcm-oss compatibility module. While you're at it, you might need aumix to turn up the sound volume
echo snd-pcm-oss >> /etc/modules modprobe snd-pcm-oss apk_add aumix sox aumix (set volume settings) play really_cool_song.mp3
Time and timezones
How do I set local timezone?
Timezone if set in the file /etc/TZ. If this is not set time will displayed in UTC. Set how other uClibc based distros does this: http://leaf.sourceforge.net/doc/buci-tz3.html http://www.sonoracomm.com/index.php?option=com_content&task=view&id=107&Itemid=32
For a more complete list over timezones see http://astronomy.physics.tamu.edu/Java/Tools/Misc/Clock/zones.html
OpenNTPD reports an error with "adjtime"
Your log display something like:
reply from 85.214.86.126: offset 865033148.784255 delay 0.055466, next query 32s reply from 202.150.212.24: offset 865033148.779314 delay 0.400771, next query 3s adjusting local clock by 865033148.779835s adjtime failed: Invalid argument
openntpd is supposed to make small adjustments in the time without causing time jumps. If the adjustment is too big then something is clearly wrong and ntpd gives up. (its actually adjtime(3) that has a limit on how big adjustments are allowed)
You can make ntpd set the time at startup by adding -s option to ntpd. This is done by setting NTPD_OPTS="-s" in /etc/conf.d/ntpd.
Packages
Can you build an apk package for ...?
Yes, I probably can. Please create an issue in the bugtracker. Mark it as "feature" include a short description (one-line), an url for the home page, and an url for the source package.
How can i build my own package?
Please see the Creating an Alpine package page.
