Hi,
I successfully compiled net-snmp-5.7.3 for HP-UX ia64.
configure script was:
'--with-default-snmp-version=3' '--enable-ipv6'
'--with-logfile=/var/tmp' '--with-persistent-directory=/var/tmp'
'--with-perl-modules=no' '--enable-embedded-perl=no'
'--with-openssl=/home/dixon/HPUX11.23_IPF64/release'
'--enable-static=yes' '--enable-shared=no'
'--prefix=/home/dixon/buildoutput_hpuxia64' 'CC=cc +DD64'
'CFLAGS=+DD64'
But i am not able to get snmptrapd working.
snmptrapd is not processing traps at all.
I suspect the fd_set returned by snmp_select_info is corrupted somehow:
I added further debug lines in apps/snmptrapd.c
@@ -587,7 +587,17 @@

timerclear(tvp);

When i run snmptrapd as:
./snmptrapd -f -D all -Lo
...
snmptrapd:: before snmp_select_info numfds=0trace:

Note:
sess_select: for all sessions: 7 5 3
snmptrapd:: fd 35 is set
snmptrapd:: fd 37 is set
Also lsof shows:
# lsof -i :162
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
snmptrapd 3893 root 7u IPv4 0xe0000001be315380 0t0 UDP
*:snmp-trap (Idle)
Therefore, at select, it waits for wrong fds and ended up not
receiving any traps ?
Thanks in advance..

Dixon Xavier
