Hi,
After I apt-get update && apt-get upgrade my Raspberry Pi, Tor doesn't
work any more. What happen is :
root@raspberrypi:/opt/cjdns# /etc/init.d/tor start
*** stack smashing detected ***: /usr/sbin/tor terminated
/etc/init.d/tor : ligne 111 : 29830 Abandon $DAEMON
$VERIFY_ARGS > /dev/null
Checking if tor configuration is valid ... failed!
*** stack smashing detected ***: /usr/sbin/tor terminated
/etc/init.d/tor : ligne 111 : 29836 Abandon $DAEMON
--verify-config 1>&2
On the advice of sysrqb, I put DisableDebuggerAttachment 0 in my torrc
file.
Then :
root@raspberrypi:/var/log/tor# gdb tor
