Board – Yeri Tiete

Selling: Pandaboard

Yeri Tiete — Mon, 26 Sep 2011 13:25:50 +0200

I’m selling my Pandaboard* board. Never used.

Selling because I could use some cash and I do not have the time (or any particular use) for it anymore. It was a dev project for a project of mine.

I’m selling my IGEPv2* board. Rarely used and works perfectly.

After upgrading my Guruplug Display from Lenny to Squeeze I came along an odd error; every non-root user was unable to access anything related to the internet.

NTP:

Mar 26 20:31:50 localhost ntpd[1055]: ./../lib/isc/unix/ifiter_ioctl.c:348: unexpected error: Mar 26 20:31:50 localhost ntpd[1055]: making interface scan socket: Permission denied Mar 26 20:35:09 localhost ntpd[1055]: ntpd exiting on signal 15

Regular user:

yeri@gplugD ~ $ ping google.be ping: unknown host google.be yeri@gplugD ~ $ ping 85.12.6.171 socket: Permission denied yeri@gplugD ~ $ ssh localhost socket: Permission denied ssh: connect to host localhost port 22: Permission denied

Root:

gplugD ~ # ping 85.12.6.171 -c 1 PING 85.12.6.171 (85.12.6.171) 56(84) bytes of data. 64 bytes from 85.12.6.171: icmp_req=1 ttl=58 time=37.1 ms — 85.12.6.171 ping statistics — 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 37.145/37.145/37.145/0.000 ms

Solution? It’s an issue (well, not really an issue, more working like intended) of this kernel flag

CONFIG_ANDROID_PARANOID_NETWORK

And you can fix it by adding the aid_inet group – and adding your user(s) too it. Don’t forget to add NTP etc as well.

gplugD ~ # groupadd -g 3003 aid_inet gplugD ~ # usermod -G -a aid_inet $YOUR-USER

Special thanks to Tim Besard!

Edit, from the Serverfault page:

On Android Jelly Bean (4.1) used on the Nexus 7, I had to use the group name inet instead of aid_inet, thus:
$ groupadd -g 3004 inet
I used 3004 instead of 3003 because 3003 was already taken by aid_inet
$ usermod -G inet Some code snippets from the Android Kernel related to this go here: http://blog.appuarium.com/2011/06/23/how-android-enforces-android-permission-internet/

Got this error on my Guruplug Display after messing with it.

Neither was I able to use su, or any other important command.

After many chmods, chowns, and cursing – check your mount (in /etc/fstab) options… ;)

Be sure / is not mounted with

nosetuid

Reboot and enjoy!
