Sharp SNMP Suite (#SNMP)

New Post: Get IF status/set/ errors

onEOFour — Fri, 09 Jan 2009 21:20:59 GMT

Turns out the issue I am expierencing is with the Walk function:

Manager.Walk(VersionCode.V2, New IPEndPoint(IPAddress.Parse(ip), 161), sCommunity, New ObjectIdentifier(IntNameOID), list, 30000, WalkMode.WithinSubtree)

If I increase the timeout to 30 seconds in this line of code, everything is successfull

Strangely, two of my xml commands will execute quickly, then there is a pause, then two more will execute quickly, and the cycle continues until all of my xml commands have been executed:

06:12:58: %SYS-5-CONFIG_I: Configured from 192.168.168.3 by snmp
06:12:58: %SYS-5-CONFIG_I: Configured from 192.168.168.3 by snmp
06:13:22: %SYS-5-CONFIG_I: Configured from 192.168.168.3 by snmp
06:13:23: %SYS-5-CONFIG_I: Configured from 192.168.168.3 by snmp
06:13:47: %SYS-5-CONFIG_I: Configured from 192.168.168.3 by snmp
06:13:47: %SYS-5-CONFIG_I: Configured from 192.168.168.3 by snmp
06:14:12: %SYS-5-CONFIG_I: Configured from 192.168.168.3 by snmp
06:14:12: %SYS-5-CONFIG_I: Configured from 192.168.168.3 by snmp

Is there any way to speed this up? Or is the problem just that the switch is not responding in a timely fashion?

Thanks again.

Hello all,

Thanks for the library!!

I've written a little app in VB.NET to get a Cisco interface status and to disable/enable the interface.

When the program is launched, it reads in an xml file with parameters like, switch IP address, port name, and what to do with the port(get status/enable/disable).

If I put only one or two lines/commands in the xml file, the program works fine. If I put several lines of things to do in the xml file, the program only completes a couple of the commands and the rest of them I get timeout/first change execption errors from the library. Heres the log of what happens when I run the program with 8 tasks to complete in the xml file.

Here's an example of what's in the xml file:

<device HDVName="GH5W" SwitchIPAddress="192.168.168.1" switchport="FastEthernet1/0/11" action="disable"></device>

sStatus = InterfaceStatus(ip, sCommunity, sIntName, IntNameOID, IntStatusOID)

' get interface status

'System.Threading.Thread.Sleep(5000)

'System.Threading.Thread.Sleep(5000)

Case "disable"

sDisableReturned = AlterState(ip, sCommunity, sIntName, IntNameOID, IntStatusOID, cAction, IntAdminStatusOID)

'System.Threading.Thread.Sleep(5000) ' wait for 5000 ms before proceeding

End Select ' end of Me.cAction

sOID = WalkNames(ip, octCommunity, sIntName, IntNameOID)

' get the string that contains OID of the interface we are looking for

If sOID <> "" Then ' if sOID is nothing it may mean the interface name was typed wrong in the workfile.xml

sInterFaceID = InterfaceID(sOID, sIntName)

' get the ID of the interface we want to control (i.e. 10037)

Dim DataArray() As String = Split(sInterFaceID, "; Data: Null", 2)

Dim LastNonEmpty As Integer = -1

For i As Integer = 0 To DataArray.Length - 1

If DataArray(i) <> "" Then

LastNonEmpty += 1

sOID = Trim(DataArray(i))

End If

ReDim Preserve DataArray(LastNonEmpty)

IntAdminStatusOID = IntAdminStatusOID +

"." + sOID ' combine the tree and the individual interface ID.

Try

Dim test As New Variable(New ObjectIdentifier(IntAdminStatusOID), New Integer32(sOIDSuffix))

Dim vList As New List(Of Variable)()

vList.Add(test)

Manager.[Set](VersionCode.V2,

New IPEndPoint(IPAddress.Parse(ip), 161), octCommunity, vList, 5000)

Catch ex As SharpOperationException

Console.WriteLine(ex)

End Try

End If

Any help you give would be appreciated. I'm not a programmer for sure, so any insight you have would be appreciated.

Thanks!!

New Post: Argument Out Of Range Exception!

ExtremeProg — Tue, 06 Jan 2009 20:13:50 GMT

Sense my last post I have added the sharpsnmplib source code project to my solution.
After doing so, I have identified the line of code that generates the error:

public static void Set(VersionCode version, IPEndPoint endpoint, OctetString community, IList<Variable> variables, int timeout)
{
    if (version == VersionCode.V3)
   {
        throw new ArgumentException("you can only use SNMP v1 or v2 in this version");
    }

   SetRequestMessage message = new SetRequestMessage(version, community, variables);
    GetResponseMessage response = message.GetResponse(timeout, endpoint);

    if (response.ErrorStatus != ErrorCode.NoError)
    {
        throw SharpErrorException.Create("error in response",
                            endpoint.Address,
                            response.ErrorStatus,
                            response.ErrorIndex,
                            response.Variables[response.ErrorIndex - 1].Id); <<<<< This line of code generates the error.
    }
}

The error occurs because "response.ErrorIndex" equals 0, making the array index equal to -1.
The response.Variables[ ] array is empty when this error occurs, therefore any index would
generate an error.

There are other open source projects in this field.

SNMP++.NET is a popular choice. However, it lacks of a natural API interface because it is based on SNMP++, a C++ project. And there is not enough documentation except this excellent Code Project article.
Indy for CLR is a .NET port of popular Delphi VCL library named Internet Direct (Indy). Now the project is hosted at here. However, the SNMP functions is not yet ported to .NET at this moment.

Project Description
Sharp SNMP Suite (#SNMP) is a free set of SNMP tools based on an open source library for developers who target Microsoft .NET/Novell Mono platforms. It is developed in C#.

(C) 2008 Malcolm Crowe, University of the West of Scotland
(C) 2008 Lex Y. Li
(C) 2008 Steve Santacroce

History
This project is based on Malcolm Crowe's research on this topic at University of the West of Scotland. You can find the original code written by Malcolm here. Now Lex Li and Steve Santacroce are the maintainers.

Design Aims of #SNMP Library

A natural API interface to encapsulate SNMP functions
A 100% Mono friendly implementation
Open source under LGPL (can be referenced by both commercial and open source applications).

Design Aims of #SNMP MIB Browser

A MIB browser that contains basic functionalities for freelance developers who cannot afford those expensive commercial tools.
Open source under BSD (can be used in most applications).

Specification Document
Specification document for #SNMP Suite is still under way. The public draft is available here.

Notice

#SNMP Library can be used in any .NET language, such as VB.NET, Managed C++, and Delphi Prism.
SNMP v2c support is almost complete in TwinTower RC2. SNMP v3 support is not yet started.
Solution and project files of #SNMP for both Visual Studio 2005 and 2008 are provided in the repository.
Sample projects are distributed in source code form only. Please find them in the source code package.
#SNMP MIB Browser is for Windows Forms only. Because of DockPanel Suite, it can only run on Windows at this moment.

License Notice
Source code of #SNMP Library is released under LGPL. BackgroundWorkerEx component authored by Roy Osherove is used, which is available here.
Source code of #SNMP MIB Browser is released under BSD. DockPanel Suite component is used, which is available here.
Source code of other samples is released in public domain.

Contact Information
You can find more information about me at my home page. Latest news about this project is always published there, too. Stay tuned.

Updated Wiki: FAQ

lextm — Tue, 30 Dec 2008 11:39:40 GMT

Is this library free for commercial projects?
Answer: It is really hard to start an open source project because you need to find a proper license. In my case, I want this library to be both strict open source and friendly to commercial world. Therefore, at last I use Less GPL to cover the code. This means if you follow LGPL rules, you can use this library in commercial projects for free.

Does it support SNMP v3?
Answer: Right now I am working hard to make most SNMP v2 support complete. Once v1 and v2c support accomplished, I can do an evaluation to see if I am capable of developing something difficult like v3.

What's the current version?
Answer: Please refer to our roadmap here.

Why should I use this library?
Answer: It is hard to explain.
On one hand, there are indeed a lot of commercial packages available throughout the market. However, my evaluation shows that most of them are too expensive and a few of them only provides limited functions a developer may need.
On the other hand, there are few open source packages existing on .NET platform. For example, I cannot compile SNMP++.NET successfully and I don't think that library provides a natural enough API interface.

Could I join this project?
Answer: Welcome. You can do a lot to help even if you may not have the chance and ability to contribute patches and new functions.
Here are a list of items I expect,
*Comments on the API. "Is it natural enough? What changes should be made to make it more natural".
*Bug reports. "Does it work in your case? What's wrong then"?
*Patches. "I found a bug and created a patch to fix it". I am more than glad to integrate patches into next release.

Does it support SNMP v3?

Answer: Right now I am working hard to make most SNMP v1 support complete. Once v1 and v2c support accomplished, I can do an evaluation to see if I am capable of developing something difficult like v3.

What's the current version?

Answer: I am working on the 0.5 builds right now because there are still lots of pieces missing. 0.5 focuses on three tasks,
SNMP v1 trap support
A friendly API interface
Make me more familiar with SNMP
Once the version number increases to 0.9, I believe it is stable enough for normal usages. And 1.0 release is going to provide full SNMP v1 coverage.

Why should I use this library?

Could I join this project?

Answer: Welcome. You can do a lot to help even if you may not have the chance and ability to contribute patches and new functions.

Patches. "I found a bug and created a patch to fix it". I am more than glad to integrate patches into next release.
New functions.
It is always hard to run a successful project myself. Thus this time I expect to have other members on board.

Why choose CodePlex.com as host?

Answer: I am not familiar with CVS or SVN and also there is no natural UI free CVS or SVN clients on Windows. Therefore, I think Teamprise's TFS client and CodePlex.com's TFS server a good match. That was why I hosted Alex, a plug in for SharpDevelop there, too.

Roadmap

Version 0.5 (Obsolete) codename: Halfbaked

A natural API interface was done in this release for major SNMP v1 related functions, including GET, GETNEXT, SET, and TRAP.

Version 0.9 (Obsolete) codename: NineHeaded

Basic MIB documents support was added in this version to make a feature complete SNMP v1 library.

Version 1.0 (Obsolete) codename: UnicornHorn

The 1.0 release was a performance tuned and bug fixed version over 0.9 with few API changes.

Version 1.1 (Obsolete) codename: UnicornHorn Refresh

The 1.1 release is a performance tuned and bug fixed version over 1.0 with a few API changes.

Version 1.5 (Current) codename: TwinTower

#SNMP MIB Browser is to be implemented in this release.

Version 2.0 codename: CrossRoad

SNMP v2c support should be completed in 2.0 release.

Version 3.0

SNMP v3 support should be completed in 3.0 release.

Other References
Two important books are read over and over again during my development. They are,

In the source code comments, a few words are cited from the books to illustrate how the code is designed.

Other Open Source Projects
There are other open source projects in this field.

SNMP++.NET is a popular choice. However, it lacks of a natural API interface because it is based on SNMP++, a C++ project. And there is not enough documentation except this excellent Code Project article.
Indy for CLR is a .NET port of popular Delphi VCL library named Internet Direct (Indy). Now the project is hosted at here. However, the SNMP functions is not yet ported to .NET at this moment.
