running net-snmp agent in windows
Hi, I'm able to compile the code with basic settings. My Configuration: net-snmp version: net-snmp-5.4.2.1 environment: cygwin operating system: windows XP Now i would like to run the snmp agent on windows. I created a snmpd.conf file in /usr/local/share/snmp with following entry: rocommunity private When i tried to do a snmpget i'm getting the following error. $ snmpget -c private localhost sysUpTime Timeout: No Response from localhost. and when i do a snmpget for netSnmpExampleInteger, i'm getting the following error: (i have compiled this by including in ./configure ... -with-mib-modules"examples/static_int") $ snmpget -c private localhost netSnmpExampleInteger.0 netSnmpExampleInteger.0: Unknown Object Identifier (Sub-id not found: (top) -> netSnmpExampleInteger ) I'm not sure whether snmp agent is running or not. How can i check this. I make sure that snmp port is not blocked (I allowed UDP port 161 in firewall settings). Can any one help me out in resolving this issue. Thanks in advance. -- ___ Net-snmp-users mailing list Net-snmp-users@lists.sourceforge.net Please see the following page to unsubscribe or change other options: https://lists.sourceforge.net/lists/listinfo/net-snmp-users

Net-SNMP 5.4.3.2.1 V3 encryption and decrytion code
Hi all, Is anymore who knows what c code does v3 encryption and decryption such as the type 'AES' in net-snmp-5.4.2.1? I want to look at the logic but so far I have no luck to find the code. What file does have the logic?

That seems to be a consequence of patch #2890931
(to add support of Counter64 values within the perl module).
I've had a quick attempt to add 'snmplib/strtoull.c' to the Win32 build
environment, but without any success. I'm inclined to reverse the
above patch (and re-open the tracker entry), so that we can get the
releases out with no further delay.
Unless anyone can provide a fix for the strtoull compilation problem
Note that the only other occurance of this call are as follows:
mibgroup/util_funcs
sctp-mib/sctp{Scalars,Tables}_linux.c
udp-mib/data_access/udp_endpoint_linux.c
(all Linux-only code)
if-mib/data_access_interface.c
(any architecture)

I doubt that will work.
Fundamentally, you need to invoke some form of shell (sh, bash, csh, etc),
since that is what will interpret the pipeline.
Anything based on "exec" will invoke the binary that's specified first
on the command line - unless this is a shell binary, then it won't understand
the pipeline syntax.
As I said to Harsszegi earlier today, the simplest answer is to use the
utility function 'run_shell_command' which explicitly invokes a shell to
run the specified command.

Another thought would be:
Since that command line actually had to spawn 3 sub-processes sort of
daisy-chained,
perhaps this might work instead (where a single sub-process is created, that
then creates
the daisy-chain (note: I haven't tried it, but its a simple experiment):
( /bin/cat /proc/cpuinfo | /usr/bin/grep vendor_id | /usr/bin/awk '{print
$3}')

RE: SNMP subagent in C + exec_command or similar
Yeah, actually I've done that :(
Copy-pasted the run_shell_command merely to my agent
(since after all it is just a system() invocation with output piped to a
temporary file).
Thanks a lot Dave for the hint!!

No - exec_command won't really help you here.
Try using "run_shell_command" instead.

No Such Instance currently exists at this OID
Hi. I have NET-SNMP 5.4.1 installed. Shortly: I can't get the values in the table Long story: I've generated template code with mib2c for tables. -mib2c -c mib2c.mfd.conf pTable Then I started the binary as an subagent: sudo ./pTable -f -L I set MIBS env -export MIBS=+ANU However, I can't get the values in the table. The following command "snmpget -v 2c -c public localhost ANU::runTime.0" gives "ANU::runTime.0 = No Such Instance currently exists at this OID". -- ___ Net-snmp-users mailing list Net-snmp-users@lists.sourceforge.net Please see the following page to unsubscribe or change other options: https://lists.sourceforge.net/lists/listinfo/net-snmp-users

RE: SNMP subagent in C + exec_command or similar
Hi,
have tried exec_command not much luck :(
I am trying to run scripts, like
cat /proc/cpuinfo | grep vendor_id | awk '{print $3}'
and similar.
No matter how I tried using SHPROC or EXECPROC (although I don't really
see SHPROC being handled at all anywhere in net-snmp)
I didn't get the pipes being executed at all.
Naturally I had to replace the command like this:
/bin/cat /proc/cpuinfo | /usr/bin/grep vendor_id | /usr/bin/awk '{print $3}'
but the output was
"processor : 0"
so 'grep' was not taking place at all :(
Any idea how to overcome this and make sure that system() is called instead of
execv()
?
