The addition of openssl dependeny in the Makefile is needed to support e.g. authentification with SHA and encryption with AES. Signed-off-by: Christian Korber <ckorber@tdt.de>
This commit implements SNMPv3 functionality to snmpd.init. In particular it adds function snmpd_snmpdv3_add, which sets the needed options in /var/run/snmpd.conf. Signed-off-by: Christian Korber <ckorber@tdt.de>
This commit adds logging to syslog and to a logfile. Signed-off-by: Christian Korber <ckorber@tdt.de>

Please make this optional. Enabling this unconditionally would result in my images being too large for my APs with 16MiB flash. |

Also, I would not remove that deprecated setting just like that. Maybe make the init script very verbose about it being deprecated and removed in X time. Both in stdout and using logger. People might be using it, and possibly breaking existing configs without any warning is something I really cannot tolerate. |

I will look into your suggestions on Monday. I understand your point with the port topic and I can undo that. Thank you for the review! |

You could have a look at the lldp package for inspiration - it has optional snmp support. |

Description:
Openssl is needed to implement encryption and authentification for SNMPv3,
therefore the Makefile is modified for that purpose.
Also snmpV3 prerequisites are added to snmpd.init file and the possibility
to log messages to syslog or a log file.
At last the deprecated option to specifiy a port at
snmpd_trap_hostname_add()and
snmpd_trap_ip_add()is removed.
