Hi Gonzalo,

Below is how to reproduce it,

1. Check out #SNMP Change Set 41774
http://sharpsnmplib.codeplex.com/SourceControl/list/changesets

2. Use xbuild to build SharpSnmpLib.sln.

3. Go to TestAgent/bin/Debug, open a prompt.

4. Use su to run mono snmpd.exe.

5. Click Disabled button so this application starts to monitor port 161 on all
incoming SNMP messages.

6. Then open SharpSnmpLib.sln in MonoDevelop.

7. Open the Unit Tests panel and go to TestGetRequestMessage.TestTimeOut test
case.

8. Execute this test case.

The test case is simply that I send a UDP packet to a nonexisting IP address in
my network and expect a SocketException for timeout.

On Windows, a SocketException whose ErrorCode is 10060 is there, so #SNMP will
package it up to TimeoutException.

But on Mono/openSUSE, I receive a SocketException whose ErrorCode is 10035.
This breaks the test case.

I am not the only one who hits this issue, and you can check this StackOverflow
post,
