+Subject: Patch for libsnmp (openwrt) to work with ipsec-if
+Content-Type: text/plain; charset=ISO-8859-1
+Content-Transfer-Encoding: 7bit
+
+Hello,
+
+I've a small patch for net-snmp (5.1.2) which is needed to work with
+ipsec-interfaces. Otherwise snmpd will segfault which means snmp is not
+really usable.
+
+The patch is from me, but the source for the fault is from:
+
+http://lists.openswan.org/pipermail/users/2004-August/001773.html
+
+It works, because this  email is going out over ipsec using a
+snmp-monitored wrt54g. ;)
