Hi all,
On Linux, I'm afraid snmpd doesn't respond correct value on ipReasmTimeout.
Currently, it looks at the value of ipReasmTimeout in /proc/net/snmp.
However, it's the number of IP pacakets the kernel is not able to reassmble
because of the timeout. /proc/sys/net/ipv4/ipfrag_time is correct proc file.
Here's the patch for CVS (2007/Feb/20)
I confirmed this patch with linux-2.6.20 and OpenSUSE 10.2.
I didn't any change at agent/mibgroup/mibII/kernel_linux.c where
ipReasmTimeout is got before because I think the value is overridden by
new code, and I fear the modification at the file affects the other objects.
If you think it's necessary to modify that file, please let me know.
I will create a revised patch.
Thank you,
