>Description:
I have set the shell for the root user to bash. The system has a PPPoE configuration to connect to Telekom DSL. In /etc/rc.conf, the following PPP configuration is entered:
ppp_enable="YES"
ppp_nat="NO"
ppp_profile="telekom"
ppp_mode="ddial"

On boot, the system does not activate this configuration. The ppp daemon is not started. Starting it manually works fine.


>How-To-Repeat:
Use bash (/usr/local/bin/bash) as shell for root. The Internet connection is not established on system boot after that.
>Fix:
In the Internet, I found a forum entry from 2005 describing the same problem (https://www.bsdforen.de/showthread.php?p=82530). The solution was to use /bin/csh as shell for root. After this change, the PPP configuration at system boot works as expected. I did no further debugging of this problem yet, but I assume that somewhere in the rc.d scripts /bin/csh is assumed to be the shell of the root user. This is clearly a bug which should be fixed.
