Access network from within proot?

[almr...@gmail.com]

Hi,

I cant get network to run in proot jail.

I have a 3.4 arm kernel (kitkat android with selinux) and I am root.

I start proot with:

./proot-arm -R /data/archlinux/

This happens when I run ping:

[root@localhost ~]# ping

Usage: ping [-aAbBdDfhLnOqrRUvV] [-c count] [-i interval] [-I interface]

Do you have any ideas?

Selinux/bind issue?

No selinux-specific prints are printed in logs...

This is unexpected, and I can't reproduce this on x86_64. Maybe it's
a PRoot bug on ARM, I'm investigating it. In the mean time, could you
test with another network command (like telnet) ?

This seemed to me to be connected to the fact that ping is a setuid
binary, when I was working with PRoot on android.

Hope that helps! :-)

Did you test with another command (like telnet) ? It could help me to
know where this issue comes from.

Hi,

No, sorry did not get around to test... I found what I needed in one of the other threads.. The gnuroot-guy had already done what I wanted to do... So i decided to go with his stuff...;)
