| | == How do I set the local timezone? == |
| This is a list of '''frequently asked questions''' about Alpine Linux. If your question is not answered on this page, use the search box above to find work in progress pages not linked here, or in case of no answer, edit this page and write down your question.
| |
| {{Tip| Prepare your question. Think it through. Make it simple and understandable.}}
| |
|
| |
|
| =General=
| | /etc/timezone and the whole zoneinfo directory tree are not supported. |
| | To set the timezone, set the TZ environment variable as specified in |
| | http://www.opengroup.org/onlinepubs/007904975/basedefs/xbd_chap08.html |
| | or you may also create an /etc/TZ file of a single line, ending with a |
| | newline, containing the TZ setting. For example |
| | echo CST6CDT > /etc/TZ |
| | ''Source: http://www.uclibc.org/downloads/Glibc_vs_uClibc_Differences.txt'' |
|
| |
|
| == I have found a bug, where can I report it? ==
| | For more information, see how other uClibc-based distributions do this: |
| You can report it on the [http://bugs.alpinelinux.org/ bugtracker].
| | * http://leaf.sourceforge.net/doc/buci-tz3.html |
| | * http://www.sonoracomm.com/index.php?option=com_content&task=view&id=107&Itemid=32 |
|
| |
|
| == Alpine freezes 1 minute when booting from Compact Flash, how can I fix? ==
| | For a more complete list of timezones, please see: http://en.wikipedia.org/wiki/List_of_tz_database_time_zones |
| Append '''nodma''' to the ''append'' line in syslinux.cfg.
| |
| | |
| == How can I contribute? ==
| |
| You can contribute by using the software and giving feedback.
| |
| You can contribute by documenting your Alpine Linux experiences on this wiki. You can contribute in many other ways. Please visit [[Contribute|Contribute page]] to read more about this topic.
| |
| | |
| Your contributions are highly appreciated.
| |
| | |
| == How do I remove the CDROM? ==
| |
| Since the modloop loopback device is on CDROM you cannot just 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 it's possible to run ''eject'' to eject the cdrom.
| |
| | |
| == Why don't I have man pages or where is the 'man' command? ==
| |
| The 'man' command and man pages are not installed by default.
| |
| | |
| * First, install the man package:
| |
| : {{Cmd|apk add man}}
| |
| * Once that's done, install the documentation for the packages that you require man pages for:<br />(Keep in mind, however, it's possible that not all packages will have a corresponding documentation package.)
| |
| : {{Cmd|apk add <pkg>-doc}}
| |
| : For example, say you installed iptables and you now require its man pages:
| |
| : {{Cmd|apk add iptables-doc}}
| |
| <br />
| |
| In our example above, we installed the man pages (and other documentation) for iptables. We can now read it:
| |
| {{Cmd|man iptables}}
| |
| | |

| |
| | |
| == 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 is set in the file /etc/TZ. If the timezone is not set, time will displayed in UTC. Set how other uClibc based distros do 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 of timezones see http://astronomy.physics.tamu.edu/Java/Tools/Misc/Clock/zones.html | |
| | |
| == OpenNTPD reports an error with "adjtime" ==
| |
| Your log contains 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, we probably can. Please create an [http://redmine.alpinelinux.org/projects/alpine/issues/new issue] in the [http://bugs.alpinelinux.org bugtracker]. Mark it as "feature" and 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.
