Is apt-listbugs part of the default installation? In this case this
could be easily accomplished with a bug report with severity >serious
that includes the work-around.

OK, message got, we inherited a bug from Debian stretch, we are sorry
for that, but having a Beta of ASCII was intended to identify and
solve such glitches :)

Would you please mind testing the wicd package available in
ascii-proposed, and report any regression and any success, so that we
can include it in the forthcoming ASCII RC?

Thanks

KatolaZ

Dear Rowland,

please try the wicd package available in ascii-proposed. It should
work OOTB. The only change is a hard dep on net-tools, which should
solve your issue.

Please report any problem.

Hi Didier, all of what you say is true, but if there is a wicd package,
then it needs to work as expected.

As for anybody using wicd on Devuan and having slight problems, just
feel glad you are not using Ubintu 18.04. This has something called
'systemd.resolved', which, for some unknown reason, puts yet another
layer in the resolv stack and refuses to let you change
 /etc/resolv.conf

2018-03-12 Thread Didier Kryn 
    This is just to remind everyone that wicd isn't necessary - at 
least if it doesn't provide anything more than wifi config.


    I've been living without it - and without network-manager - for 
many years. All I need is wpa_spplicant and wpa_gui.


    Put the following line in wpa_supplicant.conf:

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=dialout
update_config=1

    Then make yourself a member of group dialout

    Put the following in your /etc/network/interfaces - I know it's 
deprecated, but it just works.


allow-hotplug wlan0
auto wlan0
iface wlan0 inet manual
    wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf

iface default inet dhcp

    Now everytime you want to connect to a new wifi station, open 
wpa_gui; it's intuitive. If you want wpa_supplicant to remember that 
station, then save the config.


    If you have both Ethernet and wifi, then you also need ifplugd. I 
know it's potterware, but it works and is still not infected by the disease.


    Done.

[DNG] Wicd + dhclient no longer sends the correct host name and doesn't request search domains anymore in ascii.

2018-03-11 Thread Daniel Abrecht 
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA256

I don't have time to do something about this at the moment, so I'll
just inform everyone here about this problem and add the debian
maintainers to the CC of this mail, so whomever has time or needs to
know about this at least knows about this issue.

In devuan/debian jessie, wicd does send the hostname and requests the
search domains in the DHCP reply, but in ascii/stretch, it no longer
does so. I believe it uses dhclient with a different dhclient.conf
than before, but I don't know what exactly changed. There is an option
to set the hostname in wicd, but using it doesn't have any effect and
it's off by default.

The hostname option is often used by dhcp servers to notify the local
dns resolver about new clients, which makes it possible to use their
hostname instead of their IP to access them. I think the default
should be for the hostname to be sent, because it used to be that way,
it may break existing setups and cause a lot of troubleshooting
otherwise, and I don't think not having it helps with anything.

The domain search option is important to get all search domains. A lot
of networks, mine too, are split into different parts. One for lan and
one for dmz for example. In that case, it's quiet common to have both
in the search domain list. My search domains are "dmz.abrecht.li
lan.abrecht.li". This way, I can access both, local clients and my
servers using just the hostname and don't have to write out the whole
domain. There are some other use cases too. I've only ever seen
Windows machines not requesting search domains before, but I alway
took for granted that they work everywhere else. They work by default
on iOS, Android, Mac, and usually Linux, except if using wicd+dhclient
in ascii/stretch. Not requesting the option also won't add any
security benefits, because in that case the domain name is used as
search domain. But that's insufficient for multiple domains.

I'm still on wicd version 1.7.4+tb2-4, which is the same in debian and
devuan, and not on the devuan version from backports, but that
shouldn't make a difference since these versions only differ in some
dependencies and nothing else.


I've used "tcpdump -vvv port 68 or port 67" on my dhcp server to
capture the DHCP requests. Here is one when using wicd:

Here we see that "$_HOSTNAME" was sent as hostname, instead of the
real hostname. I think this is clearly a bug. Also Option 119 wasn't
requested, which is the
