Stateful traits in Pharo?

by Johan Fabry

Hi all, I was wondering if there is an implementation of stateful traits that works in Pharo. If so, where can I get it, and is it stable ? -- Johan Fabry jfabry(a)dcc.uchile.cl - http://dcc.uchile.cl/~jfabry PLEIAD Lab - Computer Science Department (DCC) - University of Chile

Re: [Pharo-users] Newbie: Does Socket ping: 'addr' work in Pharo3.11.8 ?

by RickT

Thanks for the great response! I am not only a newbie to Smalltalk but also to any sort of network programming. I guess my exposure to 'ping' on other systems was always the ICMP flavor; so I was surprised by this implementation. As Mariano pointed out, the source code in Pharo1.0 indicates port 7: tcpPort := 7. "7 = echo port, 13 = time port, 19 = character generator port" It seems to me that a ping: method should be the ICMP kind, and a ping:port: method should be for the TCP variety. I presume an echo server could be run on ports other than 7 or 10, depending on preference. So maybe the port should be designated by the caller, and not hard-coded into the class method. I see the other reasoning from your response. Thanks again for clarifying this (and educating me). -- View this message in context: http://forum.world.st/Newbie-Does-Socket-ping-addr-work-in-Pharo3-11-8-tp22… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Alas.

So you can try the method #pingPortsOn: hostName which does: pingPortsOn: hostName "Attempt to connect to a set of well-known sockets on the given host, and answer the names of the available ports." "Socket pingPortsOn: 'www.disney.com'" ^ Socket pingPorts: #(7 13 19 21 23 25 80 110 119) on: hostName timeOutSecs: 20 ;) Mariano > > Here's the method comment, emphasis added > > "Ping the given host.
