[Solved] package required: ChinaDNS ( in AUR repo )

dfeng · 2014-08-19 03:18:24

I live in China where the GFW blocks many good services overseas.
I need and like a small tool ChinaDNS to get rid of dns pollution.
https://github.com/clowwindy/ChinaDNS
I'm not good at packaging and programming.
Can somebody help to make this package?

See Legality at the bottom. It would be against local Chinese laws to circumvent the Great Fire Wall. However, the cultural values of the West do not agree with the GFW so there is a disconnect over which should be applied to your thread.

Moving to AUR Issues...

dfeng · 2014-08-19 05:27:42

@headkase, no laws but only government orders which are actually against the constitution in China are about the GFW. and the government has never admitted the existence of GFW.
@jasonwryan, thx.

Well, you don't need any programming skills for this. When you say you're "not good at packaging", does that mean you have tried and it didn't go so well? There are a million¹ examples of packages built with setup.py in the Arch repos and the AUR, I'd suggest you use any or all of them for inspiration.

¹Exaggeration - there are actually only half a million.

I got it to build and install fine, but got an error about shadowsocks when I tried to run it.
also I'm not sure whether it should depend on python or python2, which could be part of the issue.

anyway, here's the PKGBUILD if anyone wants to work on it

depends=('python' 'shadowsocks')
makedepends=('git' 'python-setuptools')

md5sums=('SKIP')

pkgver() {
  cd "$srcdir/$_realname"
  git log -1 --format="%cd" --date=short | tr -d -
}

package() {
  cd "$srcdir/$_realname"
  python setup.py install --root="$pkgdir/" --optimize=1
}

@tomk, Because of lack of skills, I have to spend hours of searching and learning to make a package. However, an expert like you can make it within half an hour.
@ooo, In setup.py, it requires shadowsocks==2.0.11 and depends on python2.7. shadowsocks is in the community repo.

OK, if you say so. That's why I suggested you take a short cut by examining how similar packages are built. But never mind, you got someone else to do it for you, so everyone's happy.

It's builded and installed fine.

What's wrong?

Sorry, I have turn off journal log, so miss some important message.

sudo journalctl _PID=672
-- Logs begin at ***, end at ***. --
*** DFENG chinadns[672]: *** INFO     starting dns at 127.0.0.1:53
*** DFENG chinadns[672]: *** ERROR    [Errno 13] Permission denied
*** DFENG chinadns[672]: *** INFO     please use sudo to run this program

To fix it, just delete User=nobody in chinadns.service:
chinadns.service
