- <para>Your best bet here is to rebuild &man.ppp.8; by adding
- <literal>CFLAGS+=-g</literal> and
- <literal>STRIP=</literal> to the end of the <filename>/etc/make.conf</filename>, then
- doing a <command>make <maketarget>install</maketarget>
- <maketarget>clean</maketarget></command> in <filename>/usr/src/usr.sbin/ppp</filename>. When &man.ppp.8; hangs, find the
- &man.ppp.8; process ID with <command>pgrep
- ppp</command> and run <command>gdb ppp
- <replaceable>PID</replaceable></command> (as <command>gdb ppp `pgrep ppp`</command>). From the <command>gdb</command>
- prompt, you can then use <command>bt</command> to get a
- stack trace.</para>
-
- <para>Send the results to &a.brian;.</para>
