gksu-polkit does not allow arguments with launched executable

hyperhead · 04-19-2013, 04:03 PM

I am running Slackware 14 64 Bit.

I am writing a python program to launch and monitor dnscrypt-proxy

I am trying to use gksu-polkit to launch dnscrypt-proxy with arguments

e.g. gksu-polkit /usr/local/sbin/dnscrypt-proxy -d -u user -l /var/log/dnscrypt

However whenever I try to use arguments from bash prompt I get the following:

gksu-polkit /usr/local/sbin/dnscrypt-proxy -d -u user -l /var/log/dnscrypt

Code:

** (gksu-polkit:10372): WARNING **: Unknown option -d

Usage:
  gksu-polkit [OPTION...] - run programs as root

Help Options:
  -h, --help       Show help options

If I wrap the executable and arguments in double or single quotes the I get the following error:

Code:

Failed to run /usr/local/sbin/dnscrypt-proxy -d -u username -l /var/log/dnscrypt

Failed to execute child process "/usr/local/sbin/dnscrypt-proxy -d -u username -l /var/log/dnscrypt" (No such file or directory)

Has anybody every successfully launched an executable with gksu-polkit and used arguments, as far as I can tell none of the switches that are available with gksu can be used with gksu-polkit.

The program "gksu-polkit" is not part of Slackware. Where did you obtain it? Are you running Slackware or one of its derivatives?

Hi, I'm running:

NAME=Slackware
VERSION="14.0"

I pulled gksu-polkit down with sbopkg.

gksu-polkit-20100909_d7e3160-x86_64-1_SBo
polkit-0.105-x86_64-3
polkit-gnome-0.102-x86_64-1
polkit-qt-1-0.103.0-x86_64-1

I remember something like gksu is not included in the Slackware (maybe I just didn't check?!), I'm going to have to go back and see why I came to be using this. I guess I will find some way of supporting several methods of invoking dnscrypt-proxy as root.

Thanks

you can try creating a wrapper script with the content

Code:

/usr/local/sbin/dnscrypt-proxy -d -u user -l /var/log/dnscrypt

and invoke that with gksu-polkit.

or try with ktsuss (but it doesn't use polkit).

but these programs (ktsuss and gksu-polkit) are often used to launch graphical apps that need to run as root under an user session.
if you just need to launch a console application, maybe could be easier to just switch to root (with "su -") and launch it.

ktsuss did the trick, thanks.

In terms of using su, dnscrypt-proxy is launched by a Python script which is running as the desktop user and has a GUI with notification icon, so I needed to grab the root password just to launch dnscrypt-proxy / alter /etc/resolv.conf. Dnscrypt-proxy actually does end up running as the desktop user, but needs to be launched initially as root

Thanks for the help
