User [email protected] added comment http://bugzilla.novell.com/show_bug.cgi?id=547120#c486904 Summary: System.Net.NetworkInformation.Ping throws InvalidOperationException "Process has not been started" on OSX Classification: Mono Product: Mono: Class Libraries Version: 2.4.x Platform: Macintosh OS/Version: Mac OS X 10.5 Status: NEW Severity: Normal Priority: P5 - None Component: System AssignedTo: [email protected] ReportedBy: [email protected] QAContact: [email protected] CC: [email protected] Depends on: 486904 Found By: --- This bug is still reproducing on MAC OS X 10.5.8 with Mono 2.4.3_6. I've tested with the following code: using System; using System.Net.NetworkInformation; namespace ConsoleApplication { class Program { static void Main(string[] args) { Console.WriteLine("Environment.OSVersion.Platform : " + (int) Environment.OSVersion.Platform); Ping x = new Ping(); PingReply response = x.Send("www.google.com"); Console.WriteLine(response.Status.ToString()); } } } Results: Environment.OSVersion.Platform : 4 Unhandled Exception: System.InvalidOperationException: Process has not been started. at System.Diagnostics.Process.get_HasExited () [0x0003b] in /private/tmp/monobuild/build/BUILD/mono-2.4.2.3/mcs/class/System/System.Diagnostics/Process.cs:205 at (wrapper remoting-invoke-with-check) System.Diagnostics.Process:get_HasExited () at System.Net.NetworkInformation.Ping.SendUnprivileged (System.Net.IPAddress address, Int32 timeout, System.Byte[] buffer, System.Net.NetworkInformation.PingOptions options) [0x000fd] in /private/tmp/monobuild/build/BUILD/mono-2.4.2.3/mcs/class/System/System.Net.NetworkInformation/Ping.cs:283 at System.Net.NetworkInformation.Ping.Send (System.Net.IPAddress address, Int32 timeout, System.Byte[] buffer, System.Net.NetworkInformation.PingOptions options) [0x00067] in /private/tmp/monobuild/build/BUILD/mono-2.4.2.3/mcs/class/System/System.Net.NetworkInformation/Ping.cs:190 at System.Net.NetworkInformation.Ping.Send (System.String hostNameOrAddress, Int32 timeout, System.Byte[] buffer, System.Net.NetworkInformation.PingOptions options) [0x00007] in /private/tmp/monobuild/build/BUILD/mono-2.4.2.3/mcs/class/System/System.Net.NetworkInformation/Ping.cs:165 at System.Net.NetworkInformation.Ping.Send (System.String hostNameOrAddress, Int32 timeout, System.Byte[] buffer) [0x00000] in /private/tmp/monobuild/build/BUILD/mono-2.4.2.3/mcs/class/System/System.Net.NetworkInformation/Ping.cs:159 at System.Net.NetworkInformation.Ping.Send (System.String hostNameOrAddress, Int32 timeout) [0x00000] in /private/tmp/monobuild/build/BUILD/mono-2.4.2.3/mcs/class/System/System.Net.NetworkInformation/Ping.cs:154 at System.Net.NetworkInformation.Ping.Send (System.String hostNameOrAddress) [0x00000] in /private/tmp/monobuild/build/BUILD/mono-2.4.2.3/mcs/class/System/System.Net.NetworkInformation/Ping.cs:149 at (wrapper remoting-invoke-with-check) System.Net.NetworkInformation.Ping:Send (string) at ConsoleApplication.Program.Main (System.String[] args) [0x00000] The application was terminated by a signal: SIGHUP In Ping.cs I see that in BuildPingArgs method is tested that the code is running on Mac OS using "bool is_mac = ((int) Environment.OSVersion.Platform == 6);" but in my test application I get from Environment.OSVersion.Platform - 4 (UNIX). Maybe this is the problem.... +++ This bug was initially created as a clone of Bug #486904 +++ User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.2; en-US; rv:1.9.0.7) Gecko/2009021910 Firefox/3.0.7 (.NET CLR 3.5.30729) The problem occurs when calling Send(). Here's some source/sudo code that reproduces the problem. string machineName = "some_machine"; Ping ping = new Ping(); PingReply reply = ping.Send( machineName, 500 ); // throws the exception I took a look through the Mono source for the Ping class, and I'm assuming that the SendUnprivileged option is being used because it uses an actual ping Process. I think the problem might be in the BuildPingArgs function, because the arguments it's using are from the Linux version of ping. The OSX version has different usage options: usage: ping [-AaDdfnoQqRrv] [-c count] [-i wait] [-l preload] [-M mask | time] [-m ttl] [-p pattern] [-S src_addr] [-s packetsize] [-t timeout] [-z tos] host ping [-AaDdfLnoQqRrv] [-c count] [-I iface] [-i wait] [-l preload] [-M mask | time] [-m ttl] [-p pattern] [-S src_addr] [-s packetsize] [-T ttl] [-t timeout] [-z tos] mcast-group Reproducible: Always Steps to Reproduce: 1. See source above. The line that sends the ping results in the exception. Actual Results: InvalidOperationException "Process has not been started" Expected Results: Not throw an exception, and return the appropriate PingReply result. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug.
