How can I close a tcp/ip socket without killing the owning process? | How can I close a tcp/ip socket without killing the owning process? – Dr Adam Stanton About Blog Published Work Projects Dr Adam Stanton Adaptive Informatician How can I close a tcp/ip socket without killing the owning process? 2016-05-16 by adamst Problem: a program has a socket open and you want to force it to close without killing the owning process. Solution: get the file descriptor of the socket, debug the process and manually call close on the file descriptor. On Linux systems: Find the offending process: netstat -np Find the socket file descriptor: lsof -np $PID Debug the process: gdb -p $PID Close the socket: call close($FD) Close the debugger: quit Profit. From here. On OSX the incantations are differently formed: Find the offending process and file descriptor: lsof -ni TCP Debug the process: lldb -p $PID Close the socket: call (int)close($FD) Close the debugger: quit Profit.
