Query on SET phases for table objects

2018-04-04 Thread Madhusudhana R 
Hi Coders,

I have a query regarding the SET phases for table objects.

The phases of SET are as follows:
MODE_SET_RESERVE10
MODE_SET_RESERVE21
MODE_SET_ACTION2
MODE_SET_COMMIT  3
MODE_SET_FREE 4
MODE_SET_UNDO   5

SCALAR Objects:
When I do SET with multiple varbinds on scalar objects, say for below command.

snmpset -v2c -c private localhost  var1.0  i  123  var2.0 s "abcde"

the phases of SET are as follows called from handle_set_loop()

   var1 var2
 var1 var2  
   var1 var2
 var1 var2
MODE_SET_RESERVE1  ->  MODE_SET_RESERVE1 -> MODE_SET_RESERVE2 -> 
MODE_SET_RESERVE2 -> MODE_SET_ACTION -> MODE_SET_ACTION -> MODE_SET_COMMIT -> 
MODE_SET_COMMIT.



TABLE Objects:
When I do SET with multiple varbinds on Table objects, say for below command,

Snmpset -v2c -c private localhost  snmpvar1.1.4.5 i 123  snmpvar2.2.4.5 s 
"abcde"

the phases of SET are as follows called from handle_set_loop()

   Var1 var1
 var1 var1
MODE_SET_RESERVE1 -> MODE_SET_RESERVE2 -> MODE_SET_ACTION -> MODE_SET_COMMIT

   Var2 var2
 var2 var2
MODE_SET_RESERVE1 -> MODE_SET_RESERVE2 -> MODE_SET_ACTION -> MODE_SET_COMMIT
Here, the SET phases are completed for var1 first and then to var2. If there is 
any failure in setting var2, it won't affect the SET on var1.


The phases of SET are different for scalars and table objects. The phases for 
scalar objects is as per RFC 3416 but not table objects.

I need to understand whether netsnmp itself has a different SET phase for table 
objects and  scalar objects or have I done something wrong in coding ?

Appreciate any response.

Thanks in advance.

Regards,
Madhu

I don't have a preference.  I think you're collecting better information
to base a decision on than I am.

Attempting to talk HTTP to the IP gave the the impression that either
my ISP is cahoots with this company; or they're intercepting the IP
back to their advertisement page. On the upside, Google's and
cloudflare's DNS are not resolving; but, that still means point your

That means that your ISP is doing something dubious. Anyway, we could 
add a workaround for broken ISP DNS configurations using the same 
approach as for the domain names onea.net-snmp.org and twoa.net-snmp.org.

Hi Eric, Keith and All,

I am Ashutosh, and I work as a junior software developer. I got to know
about net-snmp thanks to my previous project.
I have just covered the basic source code as of now, (like snmpget.c,
snmpset.c, snmptable.c, etc.)  but would like to get involved and
contribute to the project to best of my abilities.

I'm willing to attend and any time between 1:30 AM to 3:30 AM UTC and 12:30
PM to 17:30 PM UTC would be fine by me, if that works for other developers.

Thanks,
Ashutosh

I'm wiling to take on testing BSD if you can give me the spec for the
you're using. Unfortunately, I don't  have access to an AIX hardware.

I actually found no.such.address in line 79 of T070com2sec_simple.
That host has been hijacked by barefruit.co.uk who "generates highly
targeted traffic for ISPs by replacing DNS and HTTP errors with
relevant advertising"; which is now causing the test case to fail.

Hello Keith,

This week 6 PM - 9 PM PDT works for me. Next week 6 AM - 7 AM MDT will 
work for me since I will travel to Colorado. Does this work for the 
others who are interested?
