Summary: Agent compilation failed on Digital Unix

Initial Comment:
Compilation of agent failed on OSF1 V5.1 Digital Unix in ucd-snmp version 4.2
File agent/mibgroup/mibII/tcpTable.c is not compiled because of problems with IPv6 and IPv4. inpcb structure on DU V5.1 contains IPV6 parts - s6_addr but tcpTable.c assumes that s_addr(IPv4) is used.

Solution:

replace
&inpcb.inp_laddr.s_addr
with
&IN6_EXTRACT_V4ADDR(&inpcb.inp_laddr)

and

if (inet_lnaof(inpcb.inp_laddr) == INADDR_ANY) {
with
if (IN6_IS_ADDR_UNSPECIFIED(&(inpcb.inp_laddr))) {

WARNING: udp mib seems to block snmpd in endless loop !?!?

Also, define s/osf5.h:

#include "generic.h"

#define osf4

#undef TCP_TTL_SYMBOL
#define TCP_TTL_SYMBOL "tcp_ttl"

/* var_route.c nlist symbols */
#undef RTTABLES_SYMBOL
#define RTTABLES_SYMBOL "rtable"
#undef RTHASHSIZE_SYMBOL
#define RTHASHSIZE_SYMBOL "rhash_size"


Compile standard snmpd (without any additional mibs)
./configure

Habi

Message:
So, a s_addr field doesn't exist at all?  Can you submit the compilation errors that you're seeing?  I'm confused at why it would fail to compile (I can see it failing to work properly on a ipv6 machine, but...)
