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. ;)
