Operating system: ReHat 9.0
PHP version: 5.0.3
PHP Bug Type: SNMP related
Bug description: OID's missing from PHP snmpwalk compared with command line
snmpwalk
Description:
------------
Running:
PHP-5.0.3
Net-SNMP-5.2.1
Apache-(httpd-2.0.530)
PHP config Line
./configure --with-apxs2=/usr/local/apache2/bin/apxs --with-snmp
No changes to php.ini
-----------------------------------------------------------------------
Executing snmpwalk from command line (RH Linux 9) produces different
results from snmpwalk called from php.
I have a Cisco 6509 configured for Server Load Balancing.
The MIB tree for this starts at OID .1.3.6.1.4.1.9.9.161
With the following command from the Linux shell I get the folowing
results:

Most of the indexed items are missing from the output. I believe this is
because
the php snmpwalk function does not actually call snmpwalk. It uses a
combination
of snmpget and snmpgetnext calls which do not visit every branch in the
MIB tree.
Because the indexes are part of the OID field the output of snmpget and
snmpgetnext
calls are missing vital information.
I would suggest the php snmpwalk function be coded to call the actual
snmpwalk routine.
There would then be no need for the snmprealwalk and snmpwalkoid
functions.
Reproduce code:
---------------
command line call:
