Hello

I tried to run the test suite to eventually create a test case with IPv6 IPs but found two problems:

a) The README says that I can specify certain environment variables but that does not seem to work:

$ TEST_PHP_EXECUTABLE="./sapi/cli/php" SNMP_MIBDIR="/var/lib/mibs/ietf/" ./run-tests.php ext/snmp/tests/snmp_read_mib.phpt

The output of phpinfo() called from this .phpt file shows that the environment seems to be cleared:
  Environment

  Variable => Value
  SCRIPT_FILENAME => /srv/home/james/workspace/php-src-5.4/ext/snmp/tests/snmp_read_mib.php

  Any other idea how to modify the MIB variable?


b) I propose to extract the snmpd config settings into a test-snmpd.conf and put the command line to execute the daemon with this file into the README. Saves the users from trying to figure out how to start snmpd.
In addition the below contains IPv6 IPs as well:

 $ cat ext/snmp/tests/test-snmpd.conf
 # Listen for connections from the local system only
 # Listen for connections on all interfaces (both IPv4 *and* IPv6)
 agentAddress udp:127.0.0.1:161,udp6:[::1]:161

 rocommunity public 127.0.0.1
 rwcommunity private 127.0.0.1

 rwcommunity6 private ::1
 rocommunity6 public ::1

 #Do not enable them - being set here they make appropriate OID switch into r/o
 #syslocation  "Somewhere in the world"
 #syscontact  "root"
 
 #SNMPv3 credentials
 rouser adminMD5
 rouser adminSHA
 rwuser adminMD5AES
 rouser adminMD5AES128
 rouser adminMD5DES
 createUser adminMD5 MD5 test1234
 createUser adminSHA SHA test1234
 createUser adminMD5AES MD5 test1234 AES test1234
 createUser adminMD5AES128 MD5 test1234 AES test1234
 createUser adminMD5DES MD5 test1234 DES test1234

 createUser noAuthUser
 authuser read noAuthUser noauth

And the snmpd command line would be:
  sudo snmpd -C -c test-snmpd.conf -f -Le
