Thanks sven I will check with the guys that wrote the socket chapter if we can add this snippet.

Re: [Pharo-users] Socket plugin signature - Urgent

by Sven Van Caekenberghe

Again, Pharo is a high-level language, not a low-level one. Here is a working, standalone example: "An UDP echo server on port 6666" [ Socket newUDP in: [ :socket | | loop buffer result input | buffer := String new: 256. loop := true. socket setPort: 6666. [ loop ] whileTrue: [ [ result := socket receiveUDPDataInto: buffer. result first > 0 ] whileFalse: [ (Delay forMilliseconds: 10) wait ]. input := buffer copyFrom: 1 to: result first. socket sendUDPData: input toHost: result second port: result third. (input beginsWith: #quit) ifTrue: [ loop := false ] ]. socket closeAndDestroy ] ] forkAt: Processor userBackgroundPriority named: 'UDP echo server'. "Any message sent gets echoed back" Socket newUDP in: [ :socket | | buffer result | socket sendUDPData: 'testing ', 99 atRandom asString toHost: NetNameResolver localHostAddress port: 6666. buffer := String new: 256. [ result := socket receiveUDPDataInto: buffer. result first > 0 ] whileFalse: [ (Delay forMilliseconds: 10) wait ]. socket closeAndDestroy. { result. buffer. buffer copyFrom: 1 to: result first } ]. "Send quit to stop the server" Socket newUDP in: [ :socket | | buffer result | socket sendUDPData: 'quit' toHost: NetNameResolver localHostAddress port: 6666. buffer := String new: 256. [ result := socket receiveUDPDataInto: buffer. result first > 0 ] whileFalse: [ (Delay forMilliseconds: 10) wait ]. socket closeAndDestroy. { result. buffer. buffer copyFrom: 1 to: result first } ]. In a terminal (OSX or Linux), you can send a message like this: $ nc -u 127.0.0.1 6666 foo bar foo bar quit quit HTH, Sven > On 20 Oct 2014, at 22:39, Annick Fron <list(a)afceurope.com> wrote: > > In your answer you mention 1 2 3 4 data, without specifying how many bytes they have. > Typically the IP address needs 4 bytes, so your answer 1 2 3 4 is quite incomplete. > When I receive data like that > > [28 0 203 204 â¦â¦.] > > I donât know if I have only the datagram or if I have also the IP header. > So my question is how do you group the bytes to get the IP address ??? > Where do the data start ?

Re: [Pharo-users] Socket plugin signature - Urgent

In your answer you mention 1 2 3 4 data, without specifying how many bytes they have. Typically the IP address needs 4 bytes, so your answer 1 2 3 4 is quite incomplete. When I receive data like that [28 0 203 204 â¦â¦.] I donât know if I have only the datagram or if I have also the IP header. So my question is how do you group the bytes to get the IP address ??? Where do the data start ? What headers do I have and with which syntax ????

The repositories are hosted on a private GitLab instance and the url required was of the form: ssh://git@mygitlabserver/username/project.git Everything worked fine after adding my ssh key to the ssh-agent by running the following line in a console: ssh-add ~/.ssh/private_key Maybe this helps.
