how to increase TCP window size in android for FTP? -


i trying develop simple ftp client using open source ftp4j library android. wanted know if there way can change/increase tcp window size data transfer. have tried changing receive buffer size on data socket, when checked wireshark logs window size not changing @ all, stays around 195232.

    protected socket tcpconnectfordatatransferchannel(string host, int port) throws ioexception {     socket socket = new socket();     int size = (1024*1024);     socket.setsotimeout(readtimeout * 1000);     socket.setsolinger(true, closetimeout);     socket.setreceivebuffersize(size);     socket.setsendbuffersize(size);     socket.connect(new inetsocketaddress(host, port), connectiontimeout * 1000);     log.d(tag,string.valueof(socket.getreceivebuffersize()));     return socket; }

thanks

you've done it. setting receive buffer size determines maximum receive window. platform free adjust size requested or down. check after set see value kernel gave you.

195232 pretty decent size. there's no advantage making larger bandwidth-delay product.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
