Hi,

What server ?

[A Former User]

server from TCP/IP connection

[the_]

@carter_james
Are there any services running on the server you want to connect to? Or do you only want to check if the server is still alive?

i have done TCP/IP connection between server and client in localhost.now i have cross compile the server in raspi2
with der localhost adress without a client ,in this case the server is started.But when i have changed a localhoast adress with a raspi2 adress in server code, i get this error :

Server has not started
QFile::open: File (file.log) already open

Are you starting your server twice on the same machine ?

[A Former User]

yes on the same machine. i solved the trouble i only needed to add the argument QIODevice::ReadWrite to the connectToHost fonction
thanks
