Newbie: Does Socket ping: 'addr' work in Pharo3.11.8 ?

I installed the one-click version on Windows (XP) recently and am learning Smalltalk. I am under the impression that in a Shout Workspace I can execute the line
Socket ping: 'localhost' (or some valid address). But I always get a message that it timed out. I can successfully ping the same address in a command window. Any guidance would be appreciated. |

I am loving the Smalltalk environment and language very much, thanks! (But I remain an ignorant newbie nonetheless.) I hope to later explore Seaside with Pharo as well.
To my problem: With the Pharo 1.0 image, the classVarNamed:put: message was not understood. (Same for Linux version of Pharo 1.0). With the Pharo 1.1 image you linked me to, the message was understood, but had no effect. I still cannot get Socket>>ping: to work; it always times out. And yes, I meant the OS command window ping worked. For Windows XP it is what you would call the DOS command line. I also downloaded and tried the Pharo1.0 in my VirtualBox VM running Ubuntu. I have the same problem: I can ping localhost from the Linux command line, but Pharo 1.0 ping always times out. (I am running on a Dell M90 Precision laptop. FWIW) Thanks very much for your help.

Excellent. Just in case you don't know: http://pharobyexample.org/ http://book.seaside.st/book and in progress: http://book.pharo-project.org/ To my problem: Ups...sorry. Actually that was for breaking encapsulation as NetNameResolver does not have a setter for such class variable. To do a quick test just implement a class side method in NetNameResolver like this: useOldNetwork: aBoolean UseOldNetwork := aBoolean And then evaluate: NetNameResolver useOldNetwork: true.
Ok...the network package is not the best in Pharo and we had several problems :( And yes, I meant the OS command window ping worked. For Windows XP it is Ok...I know very little about network but maybe someone can help you. cheers mariano (I am running on a Dell M90 Precision laptop.

I bought the Seaside book and am reading it and PBE. (I also stumbled upon the other book in progress by reading one of your postings.)
In Pharo1.0 image, when I defined the class useOldNetwork: message, it did not understand the UseOldNetwork variable to be assigned aBoolean, so I had to declare the class variable. It did not help ping work either. Does the Socket>>ping: work for you? Or am I the only one breaking on this? Thanks for your help! |

Hello, RickT. On Sunday, May 16, 2010, at 1:14:14 PM, you wrote:
> Does the Socket>>ping: work for you? Or am I the only one breaking on this? I am seeing a failure similar to the one that you are when pinging localhost or my own web site from Pharao, or the example in the Socket class>>ping: method. I see this in Windows XP and .. hold on ... Windows 7. If I do Socket ping: 'localhost' I get a popup about "Continue to wait for connection to localhost". When I finally say Yes to this, it returns Socket class, as shown in the method: Socket class>>ping: hostName "Ping the given host. Useful for checking network connectivity.

in Pharo1.1 latest unstable
Socket ping: 'localhost' barks immediately Socket ping: 'www.google.com' gets blocked Yes we will have drastically improve the network. Stef _______________________________________________ Pharo-users mailing list [hidden email] http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-users |

Hi Ron,
Yes, you are having the same experience. Mariano asked me to try the UseOldNetwork in Pharo1.0, but as you say, it does not exist. It does in 1.1 image which is not yet released (I think). I think we are stuck with a non-working ping. Thanks for responding! |

Hi Stefan,
Mariano asked me to try using that method to set UseOldNetwork. I only was testing the class method Socket>>ping: from the workspace, and it always timed out. It also did not work in the Pharo1.1 image that Mariano asked me to try. Thanks! |

In reply to this post by Ron Jeffries
yes I get the same behavior
in 1.1, 1.0 and in latest squeak trunk. I tried to ping www.google.com or its ip. Network code is probably the same since Squeak3.9. in 1.0 mike rueger started to fix it. Then we had to rollback parts of the change because of IVP6 problems In 1.1 we have the version mike did and we should improve it. We are waited from feedback to see if we will do the same rollback as in 1.0. Stef On May 16, 2010, at 8:17 PM, Ron Jeffries wrote: > Hello, RickT.

Hi guys. No, it doesn't work for me neither. I have checked in Pharo 1.0 and 1.1 with both: useOldNetwork as true and false.
I have debugged a little the: Socket ping: 'localhost' And the problem I found is that after calling "connectNonBlockingTo: hostAddress port: port" self primSocketConnectionStatus: socketHandle. should answer something different thanUnconnected ( 0 ), like WaitingForConnection (1) or Connected (2) check Socket class >> initialize So....I should see in VM side why primSocketConnectionStatus: socketHandle. may be returning 0 (unconnected). Now...if I ping Socket ping: 'www.google.com' The result is different as I get WaitingForConnection (1) instead of 0....but it loops forever as I always get 1 and never 2....see the loop [(status = WaitingForConnection) and: [(msecsEllapsed := Time millisecondsSince: startTime) < msecsDelta]] whileTrue: [ semaphore waitTimeoutMSecs: msecsDelta - msecsEllapsed. status := self primSocketConnectionStatus: socketHandle]. in the method waitForConnectionFor: timeout ifTimedOut: timeoutBlock I will continue to check, but my knowledge in this area is almost nil.

Hi Mariano,
Your debugging efforts match what I was finding. I was originally having problems with Socket>>connect: , which kept failing. So I thought I would just try the most minimal thing, ping. There may be problems with Socket class in general. Thanks again. |
