Re: Announcing netctl

It seems like you have a more broad use case than myself for sure.  I think if you want to get a for sure answer about whether or not you should be filing bug reports, you should ask on [arch-projects], as jouke does not seem to have posted in this thread beyond the OP.  But the development of netctl seems to primarily take place on that mailing list.

I only ever use a few wireless networks, and typically my machine is sleeping between each connection.  So I have not noticed all these things.  But I am sure that jouke would really appreciate this input, as he has been working very hard on this project.

Maybe first though, you should install the netctl-git package from the AUR and report against that since I am fairly certain there have been commits since the netctl package in testing was put together.

Re: Announcing netctl

So, I was setting up a machine with a fresh arch install, when I discovered netctl. I've opted to replace netcfg, and now I have a few questions.
I've managed to setup two profiles, one wired, one wireless. Now I have enabled both of them with

netctl enable pfname

I've also enabled via systemctl:

ifplugd.service
netctl-auto@.service
netctl-ifplugd@.service
netctl-sleep.service
also both
netctl@profile.services

I want my system configured in such a way, that when a cable is connected, ifplugd brings up the link, and ideally downs the wireless in case its up.
When no cable is available it should just use the wireless.
Apart from the 'auto-down' for the wireless, things seem to work.
But I'm getting timeout-error messages during/after startup regarding wired and strangely enough also the wireless connection when no cable is plugged. Both wireless and wired connect if cable is present during boot, but I still get the following message:

Timed out waiting for device sys-subsystem-net-devices-multi-user.service
[DEPEND] Dependency failed for Automatic wired/wireless network connection using netctl profiles

I'm sure this is because I've somehow misconfigured this, but I've read the man pages, and to be frank, info is pretty sparse atm.

Re: Announcing netctl

Hello,

how are the hooks supposed to work?
I want to rmmod my wireless module before suspending and modprobe it after resuming.
Should I simply place a bash file with commands in the /etc/netctl/hooks directory?
Till now - with netcfg - I had a root-suspend and root-resume systemd service file as described in the wiki.

Thanks in advance.

PS: the netctl-sleep.service works fine, though it hangs sometimes due to the ath9k_htc module which needs to be unloaded.

Re: Announcing netctl

Here's a python script to convert netcfg profiles. It's not at all complete (just covers the stuff I needed), but could be fancied up with special handling of keys, etc.

#!/usr/bin/python2

from re import sub

ALLCAPS = '[A-Z]{5,}'
QUOTEDP = "='.*'"

def read_file(filename):
  with open(filename, 'rb') as f:
    return f.read()

def save_file(text, filename):
  with open(filename, 'wb') as f:
    f.write(text)

def camelcase(m):
  text = m.group(0)
  return ''.join([text[0].upper()] + [l.lower() for l in text[1:]])

def unquote(m):
  text = m.group(0)
  return ''.join([l for l in text if l is not "'"])

def remove_generic(text):
    lines = text.split('\n')
    conds = \
      [ lambda l: len(l) > 0
      , lambda l: not 'Automatically' in l
      , lambda l: not 'A simple' in l
      ]
    for cond in conds:
        lines = [l for l in lines if cond(l)]
    return '\n'.join(lines)

def convert_profile(filename):
  text = read_file(filename)
  text = sub(ALLCAPS, camelcase, text)
  text = sub(QUOTEDP, unquote, text)
  text = remove_generic(text)
  text = text.strip() + '\n'
  save_file(text, filename)

if __name__ == '__main__':
  from sys import argv
  convert_profile(argv[1])

I call it like this:

for f in $(ls /etc/netctl | grep -v interfaces | grep -v examples | grep -v hooks); do ./convert_profiles.py $f; done

But you could use the glob module instead.

Re: Announcing netctl

Out of curiosity; why are the example profiles stored in /etc/netctl/examples instead of somewhere in the /usr, considering that they are not "active" nor meant to be configured by the user?

maybe the location was chosen based on /etc/skel? Another possible location would be soemthing like /usr/share/doc/netctl/examples/ I think.

It may not be standard path, but it's surely more at hand in /etc/netctl/examples than somewhere under /usr/share/...

'More at hand'? Tab-completion means the difference isn't much...

Even with tab-completion, from /etc/netctl it's *much* quicker to go into ./examples than into /usr/share/doc/netctl/examples, don't you think?

In practise that hardly makes a difference considering that the file is probably copied over only once or twice in the lifetime of the system.

Keep an eye on these, where the magic happens;

It's all there in the manpages, etcetera.

Well netctl does list ppp as an optional dependency so I would guess yes it does support it.

but that seems only in reference to pppoe.  with netcfg, I can use ppp for a pptp VPN connection.  I would like to do the same with netctl but don't see how to do.

i3status used to show the correct nework status (wireless ESSID, signal strength, DHCP state, IP address...) when I was using NetworkManager.
Now everything went 'down'.
I know it's not a netctl problem, but I'd like you help me fix this because I don't know the internals of this...

We could probably help you trouble-shoot that, but you should open a new thread for this. Please post as much related info as you can in the new thread.

Re: Announcing netctl

My netctl-ifplugd only works once.  Suppose the systemd unit is running, and I plug in my ethernet cable.  The interface is successfully configured.  Then I unplug the cable, and the interface is deconfigured.  But now the systemd unit also STOPS!  So if I plug in the cable again, nothing happens.

Basically, netctl-ifplugd has to be manually restarted every time a cable is unplugged.  This can't possibly be right.
