I confirm that with this script (there is nothing else in the script except
this) :
import netsnmp
>
> profileNb = "25"
> qosType = "0"
> value = "rbQoSProfileType"
>
> oid = netsnmp.Varbind(value, profileNb, qosType)
> result = netsnmp.snmpget(oid, DestHost = "10.0.0.1", Community =
> "private", Version = 2)
> print("%s") %(result)
It gives the segmentation fault.
I'm sorry if I didn't gave you the entire script but just parts of it and I
apologize, I understand this can be waste of time for you.
So here is the script I used to notice that WALK doesn't crash :
import netsnmp
>
> profileNb = raw_input("Which QoS Profile to edit ?\n")
>
> print("-----------")
> print("QoS Profile")
> print("-----------\n")
>
> value = "rbQoSProfileName"
> oid = netsnmp.Varbind(value, profileNb)
> resultName = netsnmp.snmpget(oid, DestHost = "10.0.0.1", Community =
> "private", Version = 2)
> print("Name = %s") %resultName
>
> value = "rbQoSProfileType"
> oid = netsnmp.Varbind(value, profileNb)
> resultType = netsnmp.snmpwalk(oid, DestHost = "10.0.0.1", Community =
> "private", Version = 2)
> print("Type = %s") % (resultType, )
>
> value = "rbQoSProfileParam1"
> oid = netsnmp.Varbind(value, profileNb)
> resultParam1 = netsnmp.snmpget(oid, DestHost = "10.0.0.1", Community =
> "private", Version = 2)
> print("CIR = %s Kbps") %resultParam1
>
> value = "rbQoSProfileParam2"
> oid = netsnmp.Varbind(value, profileNb)
> resultParam2 = netsnmp.snmpget(oid, DestHost = "10.0.0.1", Community =
> "private", Version = 2)
> print("MIR = %s Kbps") %resultParam2
>
> value = "rbQoSProfileParamTime"
> oid = netsnmp.Varbind(value, profileNb)
> resultParamTime = netsnmp.snmpwalk(oid, DestHost = "10.0.0.1", Community =
> "private", Version = 2)
> print("CT = %s") % (resultParamTime, )
>
> value = "rbAQoSProfileRowStatus"
> oid = netsnmp.Varbind(value, profileNb)
> resultRowStatus = netsnmp.snmpwalk(oid, DestHost = "10.0.0.1", Community =
> "private", Version = 2)
> print("Status = %s") % (resultRowStatus, )
And the result in the shell :
m...@sumac-clusterhead-1:~$ python test2.py
> Which QoS Profile to edit ?
> 25
> -----------
> QoS Profile
> -----------
>
> Name = tests
> rbQoSProfileType 25 = None ( None )
> Type = ()
> CIR = 1100 Kbps
> MIR = 0 Kbps
> rbQoSProfileParamTime 25 = None ( None )
> CT = ()
> rbAQoSProfileRowStatus 25 = None ( None )
> Status = ()
But now, I understand that do a WALK after a GET is not a good adea. So
let's forget this.
Going back to the simple script at the very top of this mail, I found on
this page
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=497656<http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=497656>the
same problem as mine. This is a bug reported for Debian, and I am
under
Ubuntu 8.04 completely updated. So there should be a way to solve this
problem.
