While I was playing with net-snmp, my agentx client crashed
at send() in netsnmp_tcp_send.
Can anyone provide a clue on what this file is:
../sysdeps/unix/sysv/linux/powerpc/powerpc32/socket.S:87
is it a file generated by net-snmp or a file provided
by my OS?
I am running agentx as subagent on ppc-405, and configured
net-snmp using:
CC=ppc_405-gcc CXX=ppc_405-g++ ../../net-snmp/configure
--with-openssl=/usr/local/montavista/pro/devkit/ppc/405/target/usr/include
--with-mib-modules="host misc/ipfwacc" --without-rpm
--with-out-transports="AAL5PVC IPX" --with-endianness=big
--host=ppc-ibm-linux
Thanks for any info.
