Hi,
I need some advice for compiling and using net-snmp 5.2.1.2 on
HP-UX 11.0/11i in 64 Bit mode. (I need to link libnetsnmp with
my 64 Bit applications. We currently have development environments
for HP-UX 11.0 and 11i)
Because I found no 64 Bit binaries for net-snmp I tried to
compile net-snmp using aCC (version A.03.55 on HP-UX 11.0 and
version A.03.65 on HP-UX 11i).
I used the following configure options:
---------------------------------------------------------------------------------------------------
./configure --prefix=/home/gebauer/snmp/install64 --with-cc=aCC --with-ar=ar\
--with-cflags="-D_THREAD_SAFE -D_REENTRANT -DSS_64BIT_SERVER -DRW_MULTI_THREAD
+DA2.0w +DChpux -D_LARGEFILE64_SOURCE"\
--with-ldflags="+DA2.0w" --with-sys-location=Unknown --disable-developer
--with-libs=-lnm\
--with-sys-contact="System Administrator" --with-defaults
--with-mib-modules="host disman/event-mib smux"
---------------------------------------------------------------------------------------------------
Both configure and make report some warnings, but all seems to build well.
But when I try to run my applications or use the command line utilities of
net-snmp I run into some trouble.
I have to update the ipRouteTable in an bintec X8500 router. snmpwalk/snmpget
works
on this table, but it's impossible to add a new entry with snmpset:
---------------------------------------------------------------------------------------------------
[EMAIL PROTECTED]/home/gebauer/snmp/install64/bin]>./snmpset -v 1 -c bintec
172.16.0.2 .1.3.6.1.2.1.4.21.1.1 a 172.16.0.0 \
.1.3.6.1.2.1.4.21.1.2 i 100 .1.3.6.1.2.1.4.21.1.7 a 172.16.1.1
.1.3.6.1.2.1.4.21.1.8 i 3 .1.3.6.1.2.1.4.21.1.11 a 255.255.0.0
Error in packet.
Reason: (badValue) The value given has the wrong type or length.
Failed object: RFC1213-MIB::ipRouteDest
---------------------------------------------------------------------------------------------------
The badValue error is reported by the router, as it is also logged in the router
console.
If I remove the "+DA2.0w" flag from the configure options and build a 32-Bit
version of the libraries and utilities, the same snmpset commando works fine.
In order to analyse the problem I dumped the snmp-PDUs sent by snmpset via
the "-d" option and analysed them with ethereal.

Judging from the ethereal output I think that the 64-Bit build doesn't encode
the ip-address values correctly (it sends a 64-Bit value, the router and
ethereal
expects 32-Bit).
What can I do about this problem? Do I use the correct configure options?
Are there precompiled packages for HP-UX/64Bit available?
Thanks,
Christian
