Debugging aprsc issues, tips and tricks

Enabling debug logging

Change the log level to debug by changing "-e info" to "-e debug" on the aprsc command line. Insert "-e debug" if you don't have an -e parameter.

On Debian and Ubuntu the parameter goes in /etc/default/aprsc, on the DAEMON_OPTS line. On CentOS it goes to /etc/sysconfig/aprsc. On other systems it typically goes in the init script.

Enabling core dumps on Linux

Allow binary doing setuid() to dump core:

echo 2 > /proc/sys/fs/suid_dumpable

Tune core file name pattern:

echo "/var/core/core.%e.%p.%s" > /proc/sys/kernel/core_pattern 

Create a directory within the aprsc chroot where the core can be dumped:

mkdir -p /opt/aprsc/var/core
chmod a+w /opt/aprsc/var/core
