Summary: SNMP: general child_process = spopen (command_line); problem

Initial Comment:
SNMP problem - No data received from host

check_snmp.c

for testing purpose i did replace
- child_process = spopen (command_line);
with
- child_process = spopen ("/usr/bin/ldd /opt/changed_root/bin/snmpget");
and then you can see the problem

manual test:

export LD_LIBRARY_PATH=/opt/changed_root/lib:/opt/changed_root/ssl/lib

ldd /opt/changed_root/bin/snmpget
        libnetsnmp.so.15 =>      /opt/changed_root/lib/libnetsnmp.so.15
        libgen.so.1 =>   /usr/lib/libgen.so.1
        libcrypto.so.0.9.8 =>    /opt/changed_root/ssl/lib/libcrypto.so.0.9.8
        libkstat.so.1 =>         /usr/lib/libkstat.so.1
        libelf.so.1 =>   /usr/lib/libelf.so.1
        libm.so.1 =>     /usr/lib/libm.so.1
        libnsl.so.1 =>   /usr/lib/libnsl.so.1
        libsocket.so.1 =>        /usr/lib/libsocket.so.1
        libadm.so.1 =>   /usr/lib/libadm.so.1
        libc.so.1 =>     /usr/lib/libc.so.1
        libgcc_s.so.1 =>         /usr/local/lib/libgcc_s.so.1
        libdl.so.1 =>    /usr/lib/libdl.so.1
        libmp.so.2 =>    /usr/lib/libmp.so.2
        /usr/platform/SUNW,Sun-Fire-V210/lib/libc_psr.so.1

where the generated command from check_snmp.c works fine

/opt/changed_root/bin/snmpget -t 1 -r 5 -m '' -v 2c -c gn1r0t1n0m at notsoc1 10.1.100.50:8196  .1.3.6.1.4.1.140


./check_snmp -P 2c -C gn1r0t1n0m at notsoc1 -H 10.1.100.50 -p 8196 -o .1.3.6.1.4.1.140 -v

Message:
Alex,

I think this is more a problem with your snmpget executable. You can use
crle on Solaris if you want to force /opt/changed_root/ssl/lib to be in the
LD_LIBRARY_PATH.

check_snmp has been converted so it uses a different command run library
so stderr messages will be captured better.

Marking this call in pending, so will auto close in 7 days if there is no
response.

Ton

Solution added:

Is it possible change the code so that ./configure has a parrameter
LD_LIBRARY_PATH
that then is passed in popen.c please

Ohterwise we need everytime change again your code. Thanks in advance


popen.c

FILE *
spopen (const char *cmdstring)
{
-        char *env[2];
+       char *env[3];

        env[0] = strdup("LC_ALL=C");
-       env[1] = '\0';
+       env[1] =
strdup("LD_LIBRARY_PATH=/opt/changed_root/lib:/opt/changed_root/ssl/lib:/usr/local/lib");
+      env[2] = '\0';
